🚀Upper GI oral abstracts #ESMO26 Day 1 summary results
1) Arcotatug tavatecan improved PFS in CLDN18.2+ G/GEJA in the 3L+ setting
2) SANO trial, OS at 5 years similar between active surveillance and surgery in patients with oesophageal cancer and a complete clinical response after nCR, despite more distant metastasis
3) Adding pembrolizumab to dCRT did not improve EFS in untreated unresectable esophageal or GEJ cancer with PD-L1 CPS ≥10
4) Daraxonrasib demonstrated consistent OS benefit in different RAS mutatin subgroups in RASolute-302
5) mKRAS-specific lymph node targeted amphiphile immunotherapy in PDAC did not met primary DFS endpoint.
6) Zani + CT +/- tisle keep OS benefit in at IA2 of HERIZON-GEA-01
7) Anbenitamab plus ChT improved OS in patients with HER2-positive GC/GEJC adenoca after previous trastuzumab
8) TQB2102 (HER2 bispecific antibody-drug conjugate) plus bemotrizumab and capecitabine demonstrates promising antitumor activity in 1L of advanced GC/GEJC
9) Dostarlimab in Pts with localized dMMR/MSI-H GEA led to a 62.5% 1y-cCR at the first interim analysis, enabling organ preservation.
10) FOLFIRI and Ram vs paclitaxel in taxan-pretreated GEA imporved PFS but no OS
11) Stage II–IIIB gastric cancer after D2 resection, four months of adjuvant XELOX was noninferior to six months for 3-year DFS
12) Adding durvalumab to dCRT in locally advanced esophagus carcinoma did not improve PFS
13) Adding SBRT to MFOLFIRINOX in high risk, borderline resectable or locally advanced pancreatic cancer mproved LRR and PFS
14) FGFR2b expressing GC/GEJ with co-existing FGFR2 amp may define a biologically distinct subset with potential sensitivity to bemarituzumab

🚨 Perioperative immunotherapy in MIBC at #ESMO2026. Three phase III trials, three different answers, and one uncomfortable lesson for those of us who report pCR. 🔬
📊 NIAGARA (durvalumab + GC, n=1,063): pCR 37.3%, EFS HR 0.68 (0.56–0.82), OS HR 0.75 (0.59–0.95) ✅
📊 KEYNOTE-866 (pembrolizumab + GC, n=907): pCR 44.4%, EFS HR 0.88 (0.71–1.10), OS HR 1.00 (0.76–1.27) ❌
📊 CA017-078 (nivolumab + GC, n=653): pCR 39.1%, EFS HR 0.94 (0.71–1.25), OS HR 0.88 (0.64–1.21), OS immature ❌
Cross-trial, not head to head. Populations, schedules, follow-up (34 to 55 months) and statistical design all differ, so the ranking is exploratory.
But look at the direction. The trial with the highest pCR returned an OS hazard ratio of exactly 1.00. 🧠
Three points from the pathology side:
1️⃣ pCR is a response marker, not a surrogate. Comparable absolute pCR gains of roughly 9 to 10 points across all three, divergent survival. If pCR tracked cure, that pattern should not be possible. pCR remains elusive at least for standard chemotherapy plus IO.
2. And pCR itself is not standardised across trials. ypT0N0 depends on sampling protocol, block numbers, regression assessment and whether review is central or local. The NIAGARA figure quoted here comes from a reanalysis, which tells you the endpoint moved on re-review. A 9-point difference is not comfortably above that measurement noise.
Also worth noting: NIAGARA and KEYNOTE-866 both gave adjuvant IO, CA017-078 did not. So adjuvant continuation alone does not explain the split either. We genuinely do not know why these diverged. 🎯
Which is the real message. We are comparing trials on an endpoint we produce, that is not validated, not standardised, and not stratified by biology. Fixing that is a pathology job, and it is overdue. We need that now more than ever with neoadjuvant systemic phase becoming SOC.

Great summary below from Niklas Klümper.
Overall Day 1 message in bladder cancer: Not all perioperative IO strategies are equal. Adding PD-1/PD-L1 inhibitors to cisplatin-based chemotherapy has now failed in two large Phase 3 trials (KEYNOTE-866 and ENERGIZE), while EV + pembrolizumab-based approaches (and NIAGARA) have succeeded. Biomarker selection is increasingly important.

thanks for your reply.
Actually, neoadjuvant pembro is not necessarily the standard for resectable Stage III; based on the NADINA study and on clinical judgement, ipi/nivo combo neoadjuvant therapy is often used instead of single agent pembro.
It is paradoxical but true; the more approved or "proven" (but not FDA approved) therapies there are, the harder it is to design the next study. What is the "standard" treatment you compare to? Will all experts/investigators be able to agreed to such a standard? Will the comparison remain meaningful through trial data completion?
There are also other historical comparison trials of single agent adjuvant immunotherapy for #melanoma, whose patient cohorts and endpoints may be more comparable.
Again, it all comes down to full data disclosure tomorrow (and the inevitable simultaneous @NEJM or other publication).

Some tentative good news today for a vaccine in pancreas cancer.
- 7-valent mutant KRAS vaccine (G12D, G12R, G12V, G12A, G12C, G12S and G13D) given after surgery and completion of chemotherapy (with or without radiotherapy) in patients with stage I-III KRAS-mutant pancreas cancer.
- This did not prevent recurrence in the overall population.
- But, when split into pre-specified groups: ctDNA+ vs. ctDNA-, or presence/absence of prior radiation, there was significant (and substantial) protection.
- It's unclear how this KRAS vaccine will interact with KRAS inhibitors in the future.
The vaccine is made by Elicio Therapeutics, the data were presented by Eileen O'Reilly at ESMO - it's now moving to phase 3.

🩸🇪🇸 ESMO 2026 MYELOMA + MADRID GUIDE
Myeloma in the morning. Tapas at night. 😆
📍 Madrid | Oct 23–27
⭐ Essential session: Sat Oct 24, 08:30–10:00
Salamanca Auditorium, Hall 10
Three myeloma oral presentations:
1️⃣ 1454O—Bela-DRd in transplant-ineligible NDMM
High MRD negativity sounds excellent—but what does belamaf truly add beyond DRd? We need durable PFS, tolerability and ocular-treatment burden—not another impressive MRD snapshot.
2️⃣ 1455O—Long-term BelaRd
The important question is durability. Is frontline BCMA exposure justified when CAR-T and bispecific antibodies may be needed later?
3️⃣ 1456O—LBL-034, a new GPRC5D×CD3 bispecific in heavily pretreated RRMM
Phase I and single-arm: promising, not practice-changing. Watch duration of response, infections, EMD activity and the familiar GPRC5D taste/skin/nail toxicities.
BOTTOM LINE:
ESMO myeloma is small but focused:
➡️ Belamaf moving earlier
➡️ Another GPRC5D bispecific moving forward
➡️ No phase III result likely to change practice immediately
🍖 NOW THE IMPORTANT SESSION: IBÉRICO!
Easiest post-ESMO stop:
🥇 Cinco Jotas Padre Damián—excellent 100% ibérico de bellota and convenient after taking Metro Line 8 from IFEMA toward Nuevos Ministerios.

🍤 La Casa del Abuelo—gambas al ajillo
🍳 Casa Lucio/Huevos de Lucio—huevos rotos
🍺 Bodega de La Ardosa—tortilla, vermouth and old-Madrid atmosphere
Scientific rule: Do not confuse MRD negativity with cure.
Madrid rule: Do not confuse ordinary ham with jamón ibérico de bellota. 😆

These Kaplan-Meier curves finally separate… by about the width of a pixel...
The curves ride on top of each other for years before a modest late subatomic divergence, and then the blue arm takes a dramatic vertical plunge at the far righ, right about the time the numbers at risk collapse to single digits. Truly a triumph of statistical significance over clinical drama.
Novartis is already calling a ~20% relative reduction “clinically meaningful.” Somewhere a health economist is quietly calculating the cost per life-year for treating 5,100 patients to avert ~27 deaths.@5_utr

MASTERPLAN full publication is out!!
The RT volumes are worth a closer look. CTV = primary GTV + nodal GTV + tumour-vessel interface. The TVI extends 5 mm proximally and 5 mm distally along involved/closely adjacent vessels, for patients where surgery is likely. PTV = CTV/ITV + 5 mm. No elective nodal irradiation, and no elective perineural or celiac/SMA plexus volume specified in the protocol. That is a focused target, with gross nodal disease included.
Real-time RTQA is a big part of this story. Review identified 36 major planning deviations in 12 patients, reduced to 2 deviations in 2 patients after QA. All plans passed independent review before treatment. As a radiation oncologist, I want that detail alongside the outcomes. Reproducing the treatment means reproducing the contour review, OAR constraints and image guidance too.
Also worth keeping the treatment delivery denominator in view: only 40/49 patients assigned to SBRT actually received it (82%). The efficacy analysis is intention-to-treat. It should not be read as an outcome series of patients who all completed SBRT.
The surgical numbers need some unpacking. All comparisons below are chemo + SBRT vs chemo alone:
✅ Underwent surgery: 62% vs 44% (29/47 vs 11/25).
✅ Completed resection: 53% vs 44% (25/47 vs 11/25).
✅ R0 among all resected patients: 52% vs 36% (13/25 vs 4/11).
✅ R0 in the resected POPC subset: 62% vs 40% (13/21 vs 4/10).
POPC is the potentially operable cohort. So the 62% surgery figure includes exploration without resection, while the 62% R0 figure applies only to resected POPC patients. These are different endpoints with different denominators. None of those between-arm surgical comparisons was statistically significant. The paper also defines R0 as more than 1 mm clearance.
Adjuvant chemo is another important difference: 80% vs 36% of resected patients received it (20/25 vs 4/11). That complicates attribution within the treatment pathway. Early progression in the control group may have contributed, so this is a post-randomisation imbalance with more than one possible explanation. The post-hoc analyses were directionally consistent, but the authors explicitly caution about selection bias.
For the planning details: PTV_EVAL excluded the GI PRVs, with a minimum 3 mm PRV expansion. OAR constraints took priority over target coverage. Duodenum, stomach and small bowel D0.5cc were each constrained to <33 Gy, with V30 <5 cc. Delivery used standard linacs; breath hold was recommended, and fiducials were placed in 35/40 patients (88%). This is relevant to how we would implement the approach in practice.
With no elective nodes, isolated regional nodal relapse was 4% vs 8% (2/49 vs 2/25). Reassuring, although that does not establish the optimal elective volume (especially considering these patients went to surgery - ASTRO/NRG recommends inclusion of elective perineural coverage). Overall G3+ AEs were 70% vs 64% (33/47 vs 16/25). One G3 pancreatitis and one G2 small bowel obstruction were attributed to SBRT. The practical takeaway for me is to keep the target definition and prospective QA attached to the results, and to be precise about what the surgery and R0 numbers actually measure.
Delighted to join Dr Yi-Chen Zhang, Dr Calvo de Juan and Prof Yi-Long Wu in discussing the role of local therapy in non-small cell lung cancer at #ESMO26 in #Madrid this afternoon.

INCB123667 + bev in #PROC. Selective CDK2 inhibitor, n=23. ORR 48%, mPFS 7.4 mo, responses after PARPi and after prior bev.
Single arm. Bev alone in PROC was about 16%. MAESTRA 3 will test CDK2i + bev vs bev.
87% cyclin E1 overexpressed, so IHC barely selects. We need response by CCNE1 amplification.
Endometrial was in phase 1. All three pivotal trials are ovarian. 28% of p53abn endometrial cancers carry CCNE1 amplification, enriched in carcinosarcoma. That cohort deserves its own trial. #gyncsm #ESMO26
Sad that the @myESMO embargo was broken...
It is difficult to compare results between an adjuvant study and a neoadjuvant study (ie, S1801) in any cancer, including #melanoma. The patient populations were different and the primary endpoint (RFS vs EFS) was of necessity different for technical reasons that as @adamfeuerstein points out don't translate well to this platform. Until tomorrow's presentation we won't have all the data necessary to even try and compare.
It is also important to note that NO drugs are technically @FDA approved for neoadjuvant treatment for melanoma. It's a moot point as several studies including S1801 and NADINA have made neoadjuvant therapy standard of care in some situations.
I think it's great that the study (that I participated in) appears to have hit its primary endpoint, which typically ultimately translates into FDA approval.
Tomorrow (1030 ET) will be interesting...

8/8 My takeaways: cyclin E1 overexpression by IHC is becoming the selection biomarker for CDK2 and WEE1 programs, reaching more patients than amplification.
7/8 Tolerability is the issue to solve: dose interruptions 57%, reductions 43%, discontinuations 20%, grade ≥3 fatigue 16% and thrombocytopenia 12%. Mitigation in Part 2a reportedly halved discontinuations to ~10%. https://t.co/SBSZhPia0X
6/8 OS benchmarks: ~13 mo with single-agent chemo (AURELIA), 16.9 mo with mirvetuximab in FRα-high disease (MIRASOL). High cyclin E1 usually carries worse prognosis, so a longer OS in cyclinE1+ tumors points toward a drug effect.
But: cyclin E1 status was assigned retrospectively with a proprietary cutoff, the CIs overlap and there is no control arm. ASPENOVA (azenosertib vs chemo, n≈420) and DENALI Part 2 will tell us if this holds.
5/8 Cyclin E1 IHC+ (n=48):
ORR 33.3% (37.2% in response-evaluable)
mDOR 5.5 mo
mPFS 4.1 mo (confounded by early withdrawal)
mOS 15.9 mo (95% CI 8.7–21.2)
Cyclin E1 IHC− (n=46): mOS 7.5 mo (5.8–12.3) https://t.co/k48dqY829t
3/8 Next: MAESTRA3 (NCT07797283), a phase 3 of INCB123667 + bev vs bev as first-line maintenance in cyclin E1-overexpressing EOC, starts in 2026. Cyclin E1 biology is heading to the front line.

2. Pts who do not get cCR could have a very poor prognosis under bladder-saving approaches > intensification with RC/chemoRT is very much needed

@myESMO 1st Gyn Session is here! Let's start with cervical cancer.
Tisotumab vedotin set the bar in innovaTV 301 (cORR 17.8%, mPFS 4.2 mo, OS HR 0.70). At ESMO, JSKN033, a subQ co-formulation of a biparatopic HER2 ADC + PD-L1 inhibitor, in pretreated cervical cancer (75% prior IO). At RP2D 8.4 mg/kg: ORR 52.9%, DCR 94%, mPFS 8.2 mo. ORR 56% in HER2 IHC 0 and 48% after prior IO.
SHR-A2102, a nectin-4 ADC (topo-I payload), after platinum (78% prior IO, ≤2 lines). At 6 mg/kg: cORR 47.2%, DCR 89%, mPFS 7.0 mo, mDoR 7.1 mo. G≥3 TRAEs 53% (mostly heme), no discontinuations. Phase 3 underway. #gyncsm#gyncsm
Two nectin-4 ADCs now in cervix. CRB-701 (MMAE, ASCO 2026): cORR 34%, keratitis the main issue. SHR-A2102 (topo-I, ESMO 2026): cORR 47% at 6 mg/kg, myelosuppression the main issue. Populations differ (median 3 prior lines vs ≤2), so we need randomized data.

Iza-Bren is a promising ADC, but its toxicity profile looks challenging.
Hematologic toxicity is notable, so prophylactic G-CSF may be worth considering.
Non-hematologic toxicities, such as nausea, diarrhea, and stomatitis, also appear more frequent than with TPC.

“Prespecified descriptive OS analysis.” Those words should give us pause. Calling this a “positive OS result” in a phase 3 trial manuscript is misleading when OS was outside the formal testing strategy. The results are encouraging, but an OS benefit has not been formally demonstrated in this analysis.
I’m surprised this framing passed journal review. Oncologists and patients shouldn’t need to close-read a manuscript like English professors to understand whether a trial formally demonstrated an OS benefit. Put the bottom line up front.

NATALEE 6-y results are out! #ESMO26
2.1 delta in survival at 6 years.
Thanks @Annals_Oncology for reporting subsequent therapy data!
👉Only 44.4% of control arm patients with distant recurrence received a first-line CDK4/6i
Does this survival difference truly inform clinical practice in settings where CDK4/6i are standard of care for metastatic disease?
In my opinion, the answer is no.
Look forward to INTerpath NSCLC trial data, especially in stage I. Neoadj ICI better than adj ICI, but when we miss this window INT could be a great option.
Also, maybe ICI+INT works well on micrometastatic cells that haven’t yet built an immune exclusive TME around themselves. https://t.co/IXcKC1gN36

ctDNA analysis from the EVP vs chemotherapy muscle invasive bladder cancer trial (B15/EV304) shows ctDNA is strongly prognostic at all time points for both arms. EVP has higher clearance rates across time points, underlining its ⬆️ activity. Results for the control arm are strikingly similar to the ctDNA results in the chemo control arm in the NIAGARA trial. This consistency underlines the utility of ctDNA from a prognostic perspective.#ESMO26 @OncoAlert

Perioperative EV + Pembro momentum by #DrAndersUllen in KEYNOTE-905 Ph.III ad hoc analysis of cis-ineligible MIBC.
2-yr EFS: 75.8% EV/Pembro vs 55.8% Pembro vs 41.0% surgery alone.
EFS HR 0.40 vs 0.71 (each vs control).
pCR 58.8% vs 25.3% vs 10.3%.
#ESMO26 #BladderCancer @myESMO @OncoAlert
The KN905 MIBC trial includes a 3rd, less celebrated arm of single agent pembro. Results show pembro delivers an important contribution to the EVP. The trial is small and EVP performs better, but pCR rates for pembro of 35% are in the same range as neoadjuvant cisplatin chemo while EFS/OS HRs of 0.71/O.76 vs surgery are impressive. Pembro had about half the toxicity of EVP, underlining the relevance of therapy duration. VOLGA (3 cycles of EVD), is a half way between Pembro alone and 9 cycles of EVP. @Annals_Oncology #ESMO26 @Annals_Oncology @OncoAlert
Caveats: ctDNA % drives sensitivity, and deletions are hardest. PTEN loss is spatially heterogeneous, with discordance both ways, so neither tissue nor plasma is a gold standard. PTEN loss in ctDNA only → worst OS (mOS 11 mo). Matched WBC DNA is a must: 10 "hits" were CHIP. 2/2 https://t.co/Qdfx6jaien
SANO 5-year update, #ESMO26 LBA78.
Some surprises.
Study Design:
Surveillance vs surgery after cCR to CRT in locally advanced esophageal cancer (n=309).
5-year OS ~50% vs 54% (NS), HR 1.17 (95% CI 0.77–1.77)
Distant mets 46% vs 29% (P<.01). This met rate is higher and now significant.
Reminder: only 41.4 Gy/23 fx. A pre-op, arguably non-definitive dose, especially with ~75% adenocarcinoma.
Does this apply in the DFLOT + post-CROSS era? Either way, upper GI harder to tackle non-op than hoped.

The triplet of SG (TROP2 Topo1), EV (Nectin4/MMAE) and PD-1 triplet therapy has a response rate of 81% in 21 patients in advanced bladder cancer. Complimentary targets and payload make sense .

An increasingly crowded ADC landscape in HR+/HER2− mBC, with multiple positive trials but unanswered questions about optimal sequencing.
From Dr. Babrara Pastilli’s excellent discussion at #ESMO26 https://t.co/5wLSXrSg6X
It hard to explain why 1 trial with gem/cis +/-PD(L)1 (NIAGARA) is +ve for EFS/OS and 2 very similar trials (presented today) are negative in MIBC. Potentially NIAGARA has the highest risk population, not all respond to IO and the maintenance phase the most effect- but the OS of gem/cis pembro HR of 1 is concerning. This reflects what we saw in metastatic disease with contradictory results for the big combination trials. Overall EVP looks better and more consistent #ESMO26 @myESMO @Annals_Oncology @OncoAlert

Mechanism wise there has got to be a bi-directional crosstalk between wild type RAS and PRMT5
First Daraxonrasib has greater ORR than Zoldonrasib per press release, and second:
“and partly because targeting PRMT5 may attenuate some of Rasonque’s toxicities”
Tango reports 82% tumor response rate in trial of combo therapy (Daraxonrasib plus vopimetostat) for advanced #PancreaticCancer at #ESMO26
https://t.co/iaYLkWsnsl
Reduced toxicity data is particularly important as a lower Daraxonrasib dose can be used.
I note of skepticism that the the adjuvant individualized neoantigen therapy data is not meaningful progress
In case of NSCLC- we shall learn as there are 3 separate studies ongoing (one just completing accrual!)
But scientifically…
Neoadj IO works better compared to adj IO as activated T cells need to see the “in situ vaccine” of the native tumor for long-standing benefit. Postop in micromet setting simply stated there is just no cancer cells to work with- as an analogy, for T cells to build muscles they need machines in the gym… otherwise, no lifting- no muscle…
Now the beauty of INT is that it does provide an excellent gym with the best tailored neoantigen weight machines for the immune system to work with!
So w results of Interpath-001 i’d say- T cells and all of us, lets go to the gym and Cheers on a first set of great results!

🚨 #ESMO26 Lung Cancer: the 10 studies that best capture where the field is moving
@OncoAlert
What stands out to me from the @OncoAlert faculty selection is how much the lung cancer landscape is shifting toward smarter sequencing, biomarker-defined combinations, and more selective treatment intensification.
🫁 Top Ten from Madrid:
1️⃣ DeLLphi-305 — tarlatamab + durvalumab in 1L ES-SCLC maintenance
2️⃣ Krascendo 1 — divarasib vs sotorasib/adagrasib in KRAS G12C NSCLC
3️⃣ SAFFRON — osimertinib + savolitinib after osimertinib in EGFRm/MET+ disease
4️⃣ OptiTROP-Lung04 — sac-TMT after EGFR-TKI
5️⃣ OptiTROP-Lung06 — sac-TMT + pembrolizumab in PD-L1-negative NSCLC
6️⃣ PERSEE — pembrolizumab ± chemotherapy in PD-L1 ≥50%
7️⃣ SANOVO — savolitinib + osimertinib in 1L EGFRm/MET-overexpressed NSCLC
8️⃣ IFCT-2103 DIAL — continue pembrolizumab vs observation at 6 months
9️⃣ PANKU-Lung01 — iza-bren after third-generation EGFR TKI
🔟 SARON — consolidation RT in oligometastatic NSCLC
🎯 Why this matters: these studies are not just adding new drugs. They are refining when to intensify, when to combine, when to continue, and when biology should drive the next step.
That is the real value of a “Top Ten” list: not more information — better prioritization of the data most likely to influence practice.

From all the social media reaction to yesterday’s embargo break I get the impression everyone expected a cure for melanoma.
These patients had already had their melanoma removed. They were cancer-free. The whole question was who stays that way.
These are the numbers:
82% of the vaccine group had no recurrence, against 70% without.
And the part being missed everywhere: the comparison wasn't vaccine versus nothing. Everyone got immunotherapy, already the most effective treatment we have in melanoma. The vaccine had to improve on something that already works well. That's a much harder test than most drugs ever face, and it's exactly why the number looks smaller than people hoped.
But this wasn’t about one drug that ends cancer, but treatments stacked on treatments until a disease that killed most people kills fewer.
Nobody cured melanoma this week. A therapy built individually for each patient gave a proof of concept, not a cure for everything, but that wasn’t the goal to begin with.
For many (future) melanoma patients this is still a big win. Now we need to make this progress scalable for each patient around the world.
Today at #ESMO26, the 6-year results of NATALEE will be presented. Ahead of the presentation, my personal view on the survival gains with adjuvant CDK4/6 inhibitors…
The 6-year OS rates in NATALEE were 91.86% vs 89.73%: an absolute gain of 2.1 percentage points (HR 0.809; 95% CI 0.661–0.989; nominal one-sided p=0.019).
The absolute 7-year OS gain in monarchE was 1.8 percentage points (HR 0.842; p=0.027). I do not think these gains should be dismissed as “only 2%.”
In the EBCTCG analysis, adding taxanes to anthracycline-based chemotherapy—an approach we have accepted as standard for years—provided an absolute 5-year OS gain of approximately 1.9 percentage points. The populations and follow-up periods differ, so we cannot directly compare treatment efficacy. However, the standards we use to judge a few percentage points of survival benefit should be consistent.
Moreover, 95.4% of patients in monarchE had already received chemotherapy. This survival gain represents an additional benefit on top of chemotherapy and endocrine therapy.
Patient selection, toxicity, treatment duration, and cost certainly deserve discussion. However, the survival benefit of adjuvant CDK4/6 inhibitors in appropriately selected patients should not be underestimated.

At 35.3 months of follow-up, zanidatamab + CT now shows a significant OS benefit over trastuzumab + CT: 22.9 vs 19.6 months (HR 0.76; p=0.0088).
With the addition of tislelizumab, median OS increased to 27 months, but the additional benefit was statistically borderline (HR 0.81; p=0.0502).
Considering toxicity, we need to carefully analyze which patients should receive the triplet regimen.

@myESMO @FAndreMD @curijoey @FedefedeFri @OncoAlert
Some thoughts on the INTerpath-001 backlash, and the simplistic "neoadjuvant already does better, so why bother" take. I think it misses a few important things.
➡️ First, the neoadjuvant data (S1801, NADINA) come from patients with macroscopic, clinically detectable nodal disease. INTerpath-001 also includes node-negative IIB/IIC and patients whose nodal disease only showed up on sentinel node biopsy. In the big SLN trials, about two thirds of SLN+ patients had deposits ≤1 mm. None of these patients are neoadjuvant candidates. We see the same confusion in #NSCLC all the time, when people compare stage IIIA from adjuvant trials (pathological staging) with stage IIIA from neoadjuvant trials (clinical staging). Same stage on paper, not the same patients.
➡️ Second, INTerpath-001 was designed before NADINA read out, when adjuvant anti-PD-1 was still the default for resected stage III. Judging it against today's practice is a bit of hindsight.
➡️ Third, I suspect the most logical place for a neoantigen vaccine is after neoadjuvant ICI in patients who don't reach pCR. INTerpath-009 is already testing exactly this in NSCLC, so we'll get some hints there.
➡️ And all of this comes with only an absolute ~3% increase in grade ≥3 toxicity, which also belongs in the balance.
For macroscopic stage III, the critique lands. I want to see the full data and the stage breakdown at LBA1. But I'd be careful firing at this result before we've even seen it properly.

#ESMO26 | NSABP B-42 – 15-year final analysis
After 5 years of AI-based therapy, an additional 5 years of letrozole:
• DFS: 61.6% vs 56.5% (HR 0.85).
• Distant recurrence: 6.9% vs 9.7% (HR 0.72).
The sustained reduction in distant recurrence is valuable. Given changes in post-recurrence treatment over such a long follow-up, I do not consider OS alone decisive.
However, SALSA did not demonstrate superiority of 10 over 7 years, nor did IDEAL demonstrate superiority of 10 over 7.5 years. B-42 compares 5 with 10 years.
Several questions remain:
• In which patients is 10 years superior to 7–8 years?
• Should we go beyond 10 years?
• When adjuvant CDK4/6 inhibitors are added, should we still extend endocrine therapy for this long?
Personally, I favour extending treatment to 10 years, particularly in patients at high risk of late recurrence who tolerate therapy well, and perhaps longer in selected patients.
As we reflect on the @moderna_tx adjuvant vaccine data I wanted to remind all @myESMO @sitcancer @ASCO the force that was Jeffrey W Weber @nyulangone - we will all feel his presence as data are presented. True mentor, leader, friend. https://t.co/TPDGXqCc0L
Topline ESMO data from INTerpath-001 (#Moderna's personalized cancer vaccine) reportedly leaked elsewhere: RFS HR 0.58
(Honestly shame on people for breaking embargo’s).
There is a huge divide here between physicians and non-physicians on the outcome.
To me, this was huge and clearly worked.
This hazard ratio puts it in the company of the most paradigm-changing adjuvant trials in oncology history.
Yes, the same outcome can be generated from giving pembro in the neoadjuvant space
[SWOG S1801 neoadjuvant + adjuvant pembro vs adjuvant pembro alone: EFS HR 0.58.]
That isn't the point. A peptide vaccine strategy yielded the same outcome as having a tumor in vivo. This demonstrates the tech worked, now it can be applied more broadly or potentially even supercharge the neoadjuvant space with less immunogenic tumors. Time to do better and apply to more things (like colon cancer pls).

🚨 Scientific embargoes exist for a reason: fair access to data, scientific integrity and, ultimately, patients.
Seeing a major #ESMO26 study disclosed ahead of schedule is disappointing.
I think ESMO takes its embargo policy seriously, and I would expect a breach of this magnitude to have consequences.
Science should set the timeline, not the stock market 😡
With INTerpath-001, someone clearly took a shortcut on the path to the data.

🚨 #ESMO26 | Phase III INTerpath-001 🚨
After an early embargo breach, @myESMO brought the abstract release forward!!!!!!
And yes, it’s clearly positive:
📉 RFS HR 0.58
📉 DMFS HR 0.62
But here’s the uncomfortable part: SWOG S1801 also reported an HR 0.58…simply by moving 3 doses of pembrolizumab BEFORE surgery…
☝🏼Not the same population. Not the same endpoint. Not a cross-trial comparison.
Still, in 2026, should a personalized mRNA vaccine really be benchmarked against adjuvant pembro alone?
Before calling this a new standard, I want to see the vaccine face the NEOADJUVANT era.
Same HR. Different path. And that may be the real INTerpath question 👀

#ESMO26 | TALENT
Neoadjuvant T-DXd showed very low pCR rates in HR+/HER2-low early breast cancer:
- T-DXd: 7%
- T-DXd + anastrozole: 3%
- T-DXd → chemotherapy: 9%
We should remember that pCR is a limited surrogate endpoint in HR+ disease. However, these results do not support T-DXd as an alternative to standard neoadjuvant chemotherapy.
Moreover, given the heterogeneity of HER2-low disease, I find it unsurprising that the success of T-DXd in the metastatic setting does not translate into similar outcomes in early-stage disease, despite the lower tumor burden.

Congrats to the SARON investigators! Important randomized data for a question we face all the time. 👏
Consolidation RT improved local control and PFS, but no OS benefit demonstrated: HR 0.99 (95% CI 0.63-1.55).
The RT details caught my eye. Of 62 pts who received RT, 51 had conventional treatment to the primary and only 11 had primary SABR. About 53% of the full cohort had N2/3 disease.
Side note: in the separate 13-pt ESTRO safety substudy, the most common schedules were 55 Gy/20 fx to the primary (10/13 pts) and 27 Gy/3 fx to thoracic mets (4/14 lesions). Those are substudy doses, not the dose distribution for the whole trial.
Curious how pts who actually received SABR to all sites did. That would be exploratory, but I'd like to see the dose/volume details and patterns of failure before generalizing these results to patients receiving total consolidation.
Looking forward to the full paper! #ESMO26 #radonc

GY020 didn't meet its primary endpoint: 3y success 70% w/ pembro+RT vs 73% RT alone. Leaving study counted as failure.
KM RFS numerically favored pembro, but CI crossed 1. G3/4 toxicity 43% vs 15%. RT alone remains my default here.

Encouraging pancreas SBRT data from MASTERPLAN. Adding 40 Gy/5 fx cut 12mo locoregional recurrence from 52% to 20% (P=.022).

14.8% invasive local recurrence at 5y after BCS alone in TOP-1.
Age 70+, small low-grade ER+ tumors, no RT or ET.
Most recurrences were salvaged, but that is still more treatment. I'd be cautious about routinely omitting both.
#ESMO26 #radonc
https://t.co/QD1spCSEAb
HR 0.58 is right where the phase 2b was, and they used a real pembro control, which I give them credit for.
Unfortunately this is RFS on top of a pembro backbone that was itself approved on RFS. COMBI-AD showed big adjuvant RFS and DMFS gains with no significant OS difference.
Patients who recur now have good salvage options, so treating earlier isn't necessarily curing more people.
Fever in 52% vs 8% means nobody was really blinded. I'd want OS before calling this a new standard.
‼️ Interesting commentary on INTerpath-001
No need for vaccine if pembro given neoadjuvant? Wow, await further details / data here, but what a dud!

Lots of exciting developments at #ESMO26! Several important studies were also published simultaneously in major medical journals. A few highlights:
1. Small-cell lung cancer (NEJM): Adding tarlatamab to first-line durvalumab maintenance improved median overall survival from 12.7 to 21.1 months in the phase 3 DeLLphi-305 trial.
2. HER2-positive breast cancer (NEJM): Anbenitamab, a HER2-targeted bispecific antibody, plus HB1801 improved 24-month progression-free survival to 58.5% vs 34.4% with standard therapy (HR 0.46).
3. Muscle-invasive bladder cancer (NEJM): Perioperative durvalumab plus neoadjuvant enfortumab vedotin improved 24-month event-free survival to 63.5% vs 45.1% with surgery alone.
4. HR-positive, HER2-negative breast cancer (Lancet): The EGFR/HER3-targeted bispecific antibody-drug conjugate izalontamab brengitecan doubled median progression-free survival versus chemotherapy (8.2 vs 4.0 months; HR 0.41) in the phase 3 PANKU-Breast01 trial.
5. Melanoma (Nature Medicine): Five-year RELATIVITY-047 results showed sustained overall survival benefit with nivolumab + relatlimab vs nivolumab alone (HR 0.78).

#ESMO26 Very thoughtful and balanced discussion of VOLGA trial by @MichvdHeijden , putting EV-D in perspective with EV-303/B15 on efficacy & safety.
Adding treme = more tox, no efficacy/OS gain.
Less is more!
Takeaway for next steps:
response-adapted adjuvant therapy?
@myESMO @tompowles1 @brian_rini @Uromigos
#ESMO26 Dr. Michiel van der Heijden discussed the implications of VOLGA alongside KEYNOTE-905 and KEYNOTE-B15:
🔹 EV + durvalumab doublet: EFS HR 0.51; OS HR 0.58, a 42% reduction in the hazard of death.
🔹 Triplet (+ tremelimumab): EFS HR 0.61; OS not yet significant. More toxicity, without a demonstrated advantage from CTLA-4 blockade.
🔹 Crucial difference: VOLGA used only 3 neoadjuvant cycles of EV, followed by RC and adjuvant durvalumab, without adjuvant EV.
🔹 The unresolved question: Which patients need adjuvant therapy? pCR is informative, but does not guarantee eradication of micrometastatic disease.
🚨Key message: The doublet is the regimen most likely to move forward. The next breakthrough may come from response-adapted treatment, not adding another drug.

🚨⭐ #ESMO26 | GU ONCOLOGY — DAY 2 HIGHLIGHTS
@urologysummit
A major day for both #BladderCancer and #ProstateCancer — with one message coming through clearly:
intensification only matters when it delivers durable, clinically meaningful benefit.
🟠 VOLGA | LBA2 — MIBC
Perioperative durvalumab + neoadjuvant EV in cisplatin-ineligible/refusing MIBC:
✅ 2-year EFS: 64% vs 45% | HR 0.51
✅ 2-year OS: 78% vs 69% | HR 0.58
Important survival signal — but not a head-to-head comparison with EV + pembrolizumab.
🔵 DASL-HiCaP | LBA4
Darolutamide + ADT + RT in very-high-risk prostate cancer:
✅ 4-year MFS: 95% vs 88% | HR 0.42
OS remains immature; still investigational.
🔵 PEACE-1 | 2215O
After 7.7 years of follow-up in de novo mCSPC:
✅ Median OS: 6.2 vs 4.4 years
✅ 8-year OS: 40.3% vs 27.1%
This is what durable treatment intensification looks like.
🔵 PROTEUS substudy | LBA53
Perioperative apalutamide + ADT around prostatectomy:
✅ EFS HR 0.38
Promising — but longer follow-up and setting-specific interpretation are essential.
🧬 STAMPEDE / Decipher | 2045O
Genomic risk may help identify who derives greater benefit from abiraterone for distant-metastasis prevention.
Interesting biomarker signal — not yet a basis for de-escalation.
🟠 NIAGARA molecular analysis | 4741RO
Exploratory EFS signals across molecular subtypes, including basal-squamous disease.
Still no validated biomarker to withhold perioperative durvalumab.
🟠 EV-103 | 4740RO
Long-term EV + pembrolizumab follow-up:
✅ Estimated 5-year OS: 33%
Durability matters — and so does late toxicity.
🟠 GDFATHER-NEO | 4757RO
Visugromab + nivolumab:
✅ pCR: 33.3% vs 7.7%
Intriguing, but exploratory in a small dataset.
⭐ MY CLINICAL PEARL
Not every form of intensification is equal.
What matters is proven survival or metastasis prevention, weighed against toxicity, patient selection, quality of life, and long-term treatment burden.
Precision + durable benefit — not just higher response rates.

TROPION-Breast02, brain mets subgroup at ESMO 2026. First-line Dato-DXd vs chemo in mTNBC, n=61.
CNS PFS 9.5 vs 2.6 mo, HR 0.27. Intracranial ORR 62.5% vs 37.5%. Longest intracranial response about 27 mo.
In TNBC, brain mets come early and we usually treat them locally first. This makes me ask whether a patient with small asymptomatic lesions could start Dato-DXd and defer /combine SRS
Not ready for clinic. This is a post hoc subgroup, n=30 with untreated brain mets. And even on Dato-DXd, median OS was 11.6 mo with brain mets vs 23.7 mo without. The CNS benefit is real; the prognosis is still poor. The answer needs a dedicated CNS trial. #bcsm #ESMO26

Putting STAMPEDE, ENZARAD, PROTEUS & DASL into context with the latest #ESMO26 updates:
STAMPEDE: Abiraterone-based intensification improved MFS AND OS, predominantly with RT. New #ESMO26 Decipher data suggests differential abi benefit in cN0 disease (interaction P=.01); using this to omit treatment still requires validation.
ENZARAD: At 8 years, MFS was 74% vs 72% (HR 0.88; P=.34). No significant overall MFS benefit from enza + ADT/RT. The cN1/planned pelvic RT subgroup signals remain hypothesis-generating.
DASL: new at #ESMO26: 1,106 patients; 96 weeks of daro v. placebo + ADT + prostate/bed AND pelvic RT. Four-year conventional-imaging MFS: 95% vs 88% (HR 0.42). Very-high-risk population, including selected postoperative patients. Interim analysis; OS immature.
PROTEUS main trial: Perioperative apa + ADT improved 5-year PSMA-inclusive MFS versus ADT alone: 78.2% vs 73.5% (HR 0.80). Conventional-imaging MFS was not statistically significant. #ESMO26 post hoc PSA-response analysis adds prognostic information.
PROTEUS randomized substudy: new at #ESMO26: Perioperative apa/ADT + RP/PLND (n=102) v. immediate RP/PLND (n=306). At 37.8 months’ follow-up:
• 3-year EFS: 63.0% vs 41.4%; HR 0.38.
• Secondary PSMA-inclusive MFS: HR 0.49; nominal P=.0193.
• Subsequent postoperative RT: 20% vs 43%.
The substudy strengthens a "perioperative strategy". But conventional-imaging entry followed by PSMA-inclusive endpoints matters. PSA-based EFS, conventional MFS and PSMA-inclusive MFS are different endpoints.
These trials support specific intensification strategies; they cannot rank the drugs or establish RP-versus-RT superiority. The decision remains who benefits enough to justify the ENTIRE treatment burden.
The moment I saw the overall survival curves, I wanted to stand up and applaud! 👏

Starlatamab takes a huge BiTE today out of small cell lung cancer!
Amazing PFS (0.34) and OS (0.42) HR and truly manageable added tox- 50% CRS but almost uniformly gr 1/2 and near non-existent ICANS, no new safety signal w durva combo just makes this one of the most impressive SCLC trials/ cancer trials ever..
Given extreme need for better treatments for our pts w ES-SCLC, unprecedented benefit seen in DeLLphi-305 plus availability/experience with use already it is a no-brainer to incorporate into our practice as SOC maintenance therapy on Monday… well, not Mon- whenever your flight takes you back post-#ESMO26
Amazing job by @sands_jacob and Amgen/DeLLphi team- glad we had a chance to offer such a transformational trial to our pts as well at Monte/Einstein!
With these extraordinary results starlatamab is likely to continue to expand into 1st line/LS-SCLC settings and lets just dream on- if we as a field have taken such a tasty first BiTE, can hardly wait for the next one!
Standing ovation- well deserved!

ctDNA analysis is an increasingly utilised prognostic tool in muscle invasive bladder cancer. In VOLGA 78% of the muscle invasive bladder cancer patients were ctDNA positive at baseline which was prognostic. Also, the combination of perioperative durvalumab and neoadjuvant EV cleared ctDNA in 60% of patients (using the Natera Genome assay which has increased sensitivity). Clearance was associated with much better outcomes. #ESMO26
My first ESMO oral! 🇪🇸
Our study: immunotherapy around cancer surgery becomes standard of care before we know if patients live longer, mature survival data should come first.

VOLGA also explored short periods of EV with duvalumab and tremelimumab in muscle invasive bladder cancer #ESMO26 @NEJM. Results showed EVDT improved EFS vs cystectomy (HR 0.61). Significant OS was not reached at this interim (HR 0.77 -ongoing analysis). EVDT = 10% higher rates of G3/4 toxicity and less EV delivery than the EV durvalumab arm. More is not always better. It appears the addition of treme partly compromised delivery of EV, which likely accounts for the more modest results compared to the doublet @OncoAlert
Six phase III trials. Six different stories.
Higher pCR does not guarantee better survival.
In muscle-invasive bladder cancer, EFS and OS matter more than impressive response rates.
Are we measuring what truly matters to patients?
@myESMO @OncoAlert @OpenMedicineHQ #ESMO26 @tompowles1 @urologysummit @Uromigos @Uroweb @urotoday
VOLGA explored short periods of EV (3 cycles) with duvalumab in muscle invasive bladder cancer #ESMO26 @NEJM. Results showed EVD was associated with better EFS + OS vs cystectomy alone (0.51 and 0.58 respectively). pCR 40-45% with ctDNA clearance rates of 60%. High rates of adjuvant IO therapy uptake and low rates of neuropathy suggest potential advantages of this approach which focuses the ADC in the neoadjuvant phase. It’s likely to be attractive for patients.
I thought #ESMO26 was the year of IO and this CART just came out of nowhere to smash expectations

• ORR 66.7% (4 CR, 4 PR) • 4 SD, 0 PD • mDoR not reached in responders • mPFS 24.7 mo
• 4 of 12 patients died, all labeled non-cancer related. In a cell therapy dataset I need to know what killed them.
• The 12 mix a Phase 1/2 that started in 2026 with expanded-access patients. A 24.7 mo median PFS likely utilizes the compassionate-use cases.
• SL-28 runs on "TezR" receptors, a system first described by the company's founders (one of whom presented today). I'd love to see someone else replicate it.
Have we finally entered the era of solid tumor CAR-Ts?

👑 Presidential #ESMO26! INTerpath-001: personalized mRNA vaccination reaches phase III in melanoma.
Resected stage IIB–IV melanoma, N=1,137: intismeran + pembrolizumab vs pembrolizumab.
💥 At 24 months:
• RFS: 82.2% vs 70.0% → HR 0.58
• DMFS: 88.5% vs 80.2% → HR 0.62
• Absolute gains: +12.2% RFS / +8.3% DMFS
• Benefit emerges mainly after 6 months
• Grade ≥3 AEs: 23.6% vs 20.3%
• OS still immature
A clinically meaningful new mechanism, but the real question now is positioning 🤔
For macroscopic stage III: adjuvant personalized vaccine after surgery, or neoadjuvant ipi/nivo before it? Biomarkers may ultimately decide.
Congrats to @ProfGLongMIA and all the team! 👏🏼

I admit i am very much into intismeran…and it seems many others too as it is standing room only here…
Fabulous presentation/data on the Interpath-001 trial demonstrating clear benefit of this space age bespoke neoantigen vaccine along w pembro for pts w resected high risk melanoma as to 40% or so improvement in RFS/distant met free survival
Indeed a landmark trial for precision medicine and hopefully not too Long before we see confirmation in nsclc/other trials!
Interpath- indeed makes us foresee a wonderful path and light ahead for our field!

8 Grade 5 AEs in the experimental arm, 0 in the control arm.
Of course, it could all be pure coincidence! After all, 6 of the 8 events were not considered TRAE
Perhaps it was just the excitement of being randomized to the experimental arm?
I'm genuinely curious about the independent causality assessment.

Two #ovariancancer ADC readouts at ESMO 2026, and together they challenge how we select patients.
#BEHOLD_1 mocertatug rezetecan (B7-H4, TOPO1 payload), platinum-resistant ovarian: confirmed ORR 62% at 5.8 mg/kg, median DoR 12.2 mo. Responses at every B7-H4 level. Response tracked with cathepsin B, the enzyme that cleaves the linker, and with TOP1, the payload's target.
Torvutatug samrotecan (FRα, TOPO1 payload): ORR 48% in FRα ultralow/null, 57% low, 62% high, with overlapping CIs. ctDNA complete molecular response 47%, no clean link to FRα.
What I make of it: With mirvetuximab, a DM4 payload, FRα-high was the gate. With TOPO1 payloads, the gate is falling. Nearly half of FRα-null tumors respond. The biology that predicts response sits in the payload path: release and sensitivity, not antigen density. That changes three things. Who we test: target IHC may exclude patients who would respond. How we sequence: after one TOPO1 ADC, the question is payload resistance, not a new target. How we design trials: stratify by payload biology, not by the antigen on the label.
Exploratory and single arm. But the direction is consistent, and it is where the field should look next. #gyncsm #ESMO26 @myESMO
#ESMO26 | INTerpath-001: My Personal Perspective Ahead of the Presidential Session
This innovation deserves recognition: a groundbreaking result for personalized cancer vaccines. However, in patients with macroscopic stage III melanoma who are eligible for neoadjuvant IO, this trial does not establish the added value over contemporary perioperative strategies. Neoadjuvant treatment can produce substantial responses while allowing some patients to avoid adjuvant therapy.
The trial design I would prioritize is:
Neoadjuvant IO → surgery → standard adjuvant therapy ± a personalized vaccine in patients without a major pathological response.
Here, “failure to achieve a major pathological response” is a more appropriate selection criterion than “any residual disease.” Patients with minimal residual viable tumor who still achieve a major pathological response should not automatically receive additional treatment.
This approach would direct treatment intensification toward patients at higher risk of recurrence. The key biological uncertainty, however, is that IO-resistant residual disease is not necessarily vaccine-sensitive. Whether vaccination can overcome that resistance needs to be demonstrated.
This criticism should remain specific to that population: INTerpath-001 retains distinct clinical value for patients with stage IIB/IIC disease and those who underwent surgery without neoadjuvant therapy.
NICHE-2. Keeping it short because the plot speaks for itself.
1. Rename it Chalabi's disease
2. Stop operating on patients first
For those who don't know: 111 patients with locally advanced dMMR colon cancer got one dose of ipi and two of nivo, then surgery. Zero events. A flat line.
Next up? Avoid the surgery altogether.

DESTINY-Breast Guide: 1795TiP at #ESMO26 🌍
In triple-positive mBC, can we do DB-09 induction and PATINA maintenance?
DB-09 made T-DXd + pertuzumab a 1L option. PATINA showed palbociclib + ET + HP maintenance improves PFS after induction (HR 0.75). DB-Guide puts them together.
How long to induce? In a DB-09 post hoc analysis, median time to maximal tumor reduction was ~11 mo (~16 cycles) overall and ~13 mo (~19 cycles) in HER2+/HR+ disease. A 6-cycle stop (~4 mo) lands well before most patients hit their best response.
DESTINY-Breast Guide (N=200, single-arm): 1️⃣ T-DXd + pertuzumab for 18-24 cycles (12m), or switch after 8 cycles with confirmed CR 2️⃣ Palbociclib + ET + HP maintenance 3️⃣ T-DXd retreatment at progression.
Primary endpoint: 24-mo PFS. QOL built in.

6/The ctDNA data deserve a flag: 47% complete molecular response, 87% any molecular response, with no clean relationship to FRα level. https://t.co/IZIeeOHbyL
So many highly active topo1 ADCs. The emerging biomarker work will help us better plan when to use these agents, whether the target matters, how to sequence and selection may be based on schedule and toxicity profiles. We are so close to prioritizing efficacy AND tolerability - wow.
5/ Torvutatug samrotecan (FRα/topo1)
ORR 48.1% in FRα ultralow/null, 57.1% low, 61.7% high. A gradient, yes. But the confidence intervals overlap , and nearly half of FRα-null tumors responded. So do we need a biomarker at all here? https://t.co/m2mYihxMDD
4/ In the MoRez trial, 96% of the tumors were B7-H4 + and responses occurred at every expression level. Correlative work suggests Cathepsin B, TOP1 expression and matrix remodeling all associated with response. https://t.co/cwJWw8ydje
3/ The dose story is the toxicity story. From 4.8 to 5.8 mg/kg:
Grade ≥3 neutropenia 24% → 60%
Any-grade neutropenia 49% → 87%
ILD or pneumonitis 7% overall, 8/9 grade 1-2

#ESMO26 Day 1 highlight for me: MASTERPLAN, now in Lancet Oncology.
Radiation and pancreatic cancer have a complicated history. ESPAC-1 suggested adjuvant chemoradiation hurt. LAP07 and CONKO-007 couldn't show an OS benefit after chemo. A021501 closed its RT arm for futility. PREOPANC-2 was a draw. We walked through the adjuvant side of this story in Sem Rad Onc last year: https://t.co/qGkMfyjghA
So why is MASTERPLAN different?
Phase 2, 14 sites in Australia and NZ (can i just say I love the Aus-NZ studies). 74 patients with high-risk localized PDAC, randomized 2:1 to chemo ± SBRT 40 Gy/5 after induction.
12-mo locoregional recurrence 20.2% vs 52.0%, sHR 0.44, p=0.022
PFS 11.9 vs 6.3 mo, HR 0.44
OS 22.0 vs 14.0 mo, HR 0.45
Grade ≥3 AEs 70% vs 64%.
Why did this one work when others didn't? The rad oncs can explain the physics better than I can. I just read it as better tumor zap zap.
Does it change practice? Maybe. I think we need to have a deeper conversation at every tumor board, but the juice seems worth the squeeze.

Phase III postMONARCH: Final OS Analysis
#ESMO26
@KalinskyKevin
Abemaciclib + fulvestrant numerically improved OS after CDK4/6i (32.1 vs 24.6 months; HR 0.80, P=0.11), without statistical significance.
PFS (HR 0.78), PFS2 (HR 0.76), and time to chemotherapy (HR 0.76) favored abemaciclib.
#ESMO26 | postMONARCH – Final OS
After progression on CDK4/6i + ET, median OS with abemaciclib + fulvestrant was 32.1 vs 24.6 months, but statistical significance was not reached (HR 0.80; 95% CI 0.60–1.06; p=0.11).
The 7.5-month difference in median OS is noteworthy, but these results do not make this combination a preferred second-line option for me, given the availability of biomarker-directed therapies.
#ESMO26 | Anbenitamab + HB1801
Am I reading this correctly?
55% of patients were HR-positive, yet none received endocrine therapy during the trial!
This trial started in 2023, and the comparator was THP.
Given the established role of endocrine therapy in HR+/HER2+ metastatic breast cancer, particularly during maintenance, how can we interpret these results without accounting for its omission?
This raises serious concerns about the trial design and the applicability of its findings to contemporary clinical practice.
Great session on the multidisciplinary management of uterine #sarcoma #ESMO26
Unfortunately, the “typical” presentation of a case is still an unexpected diagnosis after histerectomy for presumed fibroids.
Key take-home: refer patients early (pre-op ideally) for a center with experience in both sarcoma and Gyn malignancies; avoid morcellation at all cost; discuss with MTB since level of evidence across the care continuum is very low.

Giredestrant + everolimus improved PFS vs standard ET + everolimus in HR+/HER2− advanced breast cancer (HR 0.56; ESR1m: HR 0.38). Benefit was generally consistent across ESR1 variants, clonality, and poor-prognosis genomic subgroups.
Fantastic presentation by Karim Fizazi! PEACE-1 at 7.7 years: adding abiraterone to ADT + docetaxel improved median OS to 6.2 vs 4.4 years (HR 0.68) in de novo mCSPC. Durable benefit from upfront intensification! @myESMO #ESMO26 @oncoalert https://t.co/C6GdCHh36O

🔥 TODAY COULD BE ONE OF THE DEFINING MOMENTS OF #ESMO26! 🔥
The ESMO Presidential Symposium is always one of the highlights of the congress, and today’s session promises some truly extraordinary science!
If I had to pick ONE study with the greatest potential to change clinical practice at ESMO 2026, my choice would be DeLLphi-305.
For decades, SCLC has been one of the most challenging diseases in oncology, with far too little progress and far too few therapeutic breakthroughs.
Could DeLLphi-305 finally represent the major leap forward we have been waiting for? We already know that adding tarlatamab to durvalumab as first-line maintenance significantly improves OS compared with durvalumab alone. But today, we will finally see the numbers. And I am genuinely excited to discover just how transformative this benefit might be! My personal bet for the biggest breakthrough of #ESMO26? DeLLphi-305. @StephenVLiu @sands_jacob
Of course, the magnitude of survival benefit, safety and clinical applicability will ultimately determine its impact. But the potential is enormous. Don’t miss today’s Presidential Symposium!

⚠️ Different populations and designs—avoid cross-trial comparisons. VOLGA and EV-303 importantly include surgery-alone control arms without neoadjuvant therapy.
🔑 The next challenge: identifying who truly needs adjuvant ADC therapy—and who can safely avoid it.

#ESMO26 | DeLLphi-305 – Phase III | Presidential Symposium-1
In ES-SCLC, tarlatamab + durvalumab maintenance significantly improved outcomes vs durvalumab alone following first-line chemotherapy + durvalumab:
OS: 21.1 vs 12.7 months (HR 0.42)
PFS: 7.4 vs 1.9 months (HR 0.34)
CRS: 49.6%; grade ≥3: 0.4%.
An impressive OS benefit! Atezolizumab + lurbinectedin maintenance also demonstrated an OS benefit in IMforte (HR 0.73). Although cross-trial comparisons are inappropriate, the magnitude of the OS benefit with tarlatamab appears numerically much greater.
#ESMO26 | KEYNOTE-B49
In patients with PD-L1 CPS ≥1, HR+/HER2− mBC previously treated with ET, pembro + chemo was compared with chemo
- PFS: 6.7 vs 6.0 mo (HR 0.74)
- OS: 21.0 vs 22.2 mo (HR 1.04)
- CPS ≥10: PFS HR 0.59
I’m curious to see the subgroup analyses presented at ESMO. However, in the ADC era, this modest PFS benefit without an OS advantage has little clinical relevance to me.
Evaluating immunotherapy in combination with ADCs or after ADC treatment may be more rational in today's treatment landscape.
#ESMO26 | PREDICT-HER – Phase II
Can we biopsy every metastatic lesion in breast cancer? No.
But can we indirectly assess whole-body HER2 expression using HER2-PET? Possibly!
In 89 patients receiving T-DXd, median PFS was 27.5 vs 13.6 months in HER2-PET-positive vs negative patients (HR 0.11).
In HER2-low/zero patients, HER2-PET positivity had a 93.8% positive predictive value for response.
An exciting approach to capturing HER2 heterogeneity and refining patient selection for T-DXd.
Context: the LBA17 abstract in this post reports median PFS 13.6 vs 5.1 months in HER2-PET-positive vs negative patients (multivariable-adjusted HR 0.11, 0.05-0.26); a positive predictive value of 93.8% (15/16) in HER2-positive patients; and a negative predictive value of 100% (10/10) in HER2-low/zero patients (PREDICT-HER, ESMO 2026).

Day 3 at #ESMO26: five studies worth a closer look through a radiation oncology lens. My take on the key results and what they could mean for practice in GU, GI and lung cancers.
#RadOnc #SBRT https://t.co/iYTssWpk8o
🎯 #ESMO26 | Excellent discussion by @benlevylungdoc on SARON and PERSEE!
Two trials, two important lessons for advanced NSCLC.
🔹 SARON: Consolidative radiotherapy improved PFS and local disease control in oligo metastatic NSCLC, but no OS benefit (HR 0.99).
🔹 PERSEE: Pembrolizumab + chemo met its primary endpoint PFS but not OS though numerically better (not powered for OS) in PD-L1 ≥50% NSCLC.
Key messages from @benlevylungdoc :
• Oligometastatic disease needs better biological definition, beyond the number of lesions.
• Treatment intensification should be guided by better patient selection.
• More treatment does not automatically mean better outcomes!
- Lower threshold to add chemo to pembro in PD-L1 >50%
👏 A thoughtful discussion with practical implications for our clinics.

Another practice changing result for lung oncology at #ESMO26: PERSEE trial
👉 Academic 🇫🇷 multicentre study
👉 Which is best in 1L PD-L1 >50% NSCLC: pembro (P) or chemo+pembro (CT-P)?
What do we know already?
🔹Retrospective study suggested modest benefit of CT-P
What did this study do?
🔸 Phase 3, multi-centre, randomised
🔸 Local PD-L1 testing
🔸 1:1 P or CT-P
🔸 1’ end-point = PFS
What was found? CT-P…
✅ Improved mPFS in whole popn (HR 0.56)
✅ Improvement was in all PD-L1 levels (50-74; 75-90; 90-100%)
✅ Improvement in mOS (HR 0.77), not powered for significance
✅ Increased ORR: 77% v 50%
✅ Reduced early progression
Thoughts:
🤔 An easy way to improve the outcome for most of your PD-L1 >50% pts: add chemo to the pembro
🤔 CT-P still not for everyone: less/no benefit in >70yrs, and squamous histology
🤔 Shame PS=2 not included, to make this more real-world
🤔 Had not expected CT-P to be better across all PD-L1 levels
🤔 Pembro only still has a role in select PD-L1 high, especially >90% with KRAS G12C
Will this change my practice?
👉 I already use CT-P in PD-L1 50-80%, but I will now use it in >80% for most (but not all) pts
👏 Great study. Congratulations to authors #LCSM

📉 Grade ≥2 anorexia 15% vs 26%
⚠️ 2 treatment-related deaths in the 14-day arm
This is the regimen that I already use in practice. However, I must still say that this is the trial I wish we had more of: academic, pragmatic, about 1,000 patients, and asking how to give a drug we already use.
The 14-day schedule keeps survival and drops severe neutropenia from 39% to 13%.
In the refractory setting, where every clinic visit and every treatment delay due to neutropenia costs valuable quality time, that matters.
That said, I hope we will have better options than Lonsurf in the near future.

At the Presidential Session, the KRASCENDO-1 discussant seems to be getting more applause than the actual study presentation. Quite telling, isn't it? I wonder why… 🤔 @SuyogCancer
💊 Sotorasib and adagrasib were fundamental proof of concept drugs approved for a clear unmet need even none of them never demonstrated overall survival benefit.
🤯 Today those drugs are part of the past in oncology history.
Divarasib improve ORR, PFS and OS in previously treated KRAS G12C mutant NSCLC with a better safety profile in Krascendo1 Ph3 randomized clinical trial.

#ESMO26 Optimal induction treatment in non-metastatic bladder cancer @niklas_kluemper @urotoday
Depth of response tracks with benefit: Absolute pCR gain vs EFS HR https://t.co/L7T3XcdOuD
Rina-S vs Mirvetuximab: Same target. Different payload!
Two FRα-directed ADCs in platinum-resistant ovarian cancer — but important differences.
🔹 Rina-S (RAINFOL-02): Exatecan/TOP1 payload, broader FRα eligibility. Impressive Phase III PFS (HR 0.29) and OS (HR 0.43) results.
🔹 Mirvetuximab (MIRASOL): DM4 payload, established benefit in FRα-high disease.
🔹 The big question: Can Rina-S work after mirvetuximab? Early activity is encouraging, but definitive sequencing evidence is awaited.
⚠️ Cross-trial HRs cannot establish superiority.
Different payloads. Different populations. Sequencing remains the key question.
#ESMO26 #OvarianCancer #ADC #MVOnco @myESMO @OncoAlert
Honoured to have had the opportunity to present "Optimal induction treatment in non-metastatic bladder cancer" at #ESMO26 in Madrid!
🚨 Does a deeper pathological response translate into greater survival benefit in perioperative MIBC?
An intriguing pattern across four phase III trials:
🔹 NIAGARA: ΔpCR +10 pp | EFS HR 0.68
🔹 KEYNOTE-B15: +23 pp | HR 0.53
🔹 VOLGA: +32 pp | HR 0.51
🔹 KEYNOTE-905: +49 pp | HR 0.40
Larger absolute pCR gains appear to track with greater EFS benefit.
But the comparator matters!
KEYNOTE-905 and VOLGA used surgery-based controls without neoadjuvant systemic therapy (control "pCR" ~8–9%), whereas NIAGARA and KEYNOTE-B15 used active neoadjuvant cisplatin-based chemotherapy.
Thus, the magnitude of ΔpCR is not directly comparable across trials.
The key question: Can pCR, combined with utDNA + ctDNA clearance, become a reliable tool for response-adapted treatment intensity?
⚠️ This is an exploratory, trial-level observation—not proof that pCR improvements cause EFS benefits or that pCR is a validated surrogate endpoint!
Better biomarkers could help us maximize cure while minimizing overtreatment. 🔬

We already know that ivonescimab is effective. However, something else caught my attention on this slide.
In the control arm, 7% of patients received “Traditional Chinese Medicine” as subsequent antitumor therapy, compared with only 0.6% in the ivonescimab arm.
What exactly are these treatments? Have they demonstrated any survival benefit, or is their efficacy no better than placebo?
And the crucial question: Could this imbalance have influenced OS, given the substantially higher use in the control arm?
Have similar treatments been reported in other randomized oncology trials?

We should judge trials by the quality of their data and the benefit they bring to patients, not by their country of origin. Scientific scrutiny should follow the same standards for everyone; political biases must not delay patients’ access to effective treatments. Clearly, these studies were considered scientifically worthy of presidential presentation—just look at how many came from China!

@myESMO @ASCO
The Trojan horse was successful.
In patients with pretreated and metastatic gastric/esophageal cancer sonesitatug-vedotin doubled survival to 10.0 versus 5.0 months with standard chemo, risk of death down 53%.
And it worked even in tumors with lower levels of the target label, widening eligibility to around 60% of patients in this setting, not a narrow slice.
In a cancer where later line treatment has meant 5-9 months for my whole career, doubling that isn't small.
It’s a great success for a majority of patients, and there are more ADCs coming, also with Claudin18.2 as a target.
#ESMO26 | CLARITY-Gastric01
Doubling OS from 5 to 10 months with the CLDN18.2-targeted ADC sonesitatug vedotin in ≥3L is impressive (HR 0.47). Benefit even in patients with lower CLDN18.2 expression is encouraging.
However, the primary PFS endpoint was not met in the ITT population. Its role in 2L and efficacy after zolbetuximab remain unclear.
one question: Given that CLDN18.2 expression can change after treatment, should a fresh biopsy have been mandatory at study enrollment? Or does lowering the positivity cutoff to ≥25% reduce the clinical relevance of this discordance, making archival tissue sufficient?
Other presentación to make a reflection.

Exciting emerging data in 1L R/M #HNSCC at #ESMO26!
🔹 OrigAMI-4: Amivantamab (EGFR×MET) + pembrolizumab + carboplatin: ORR 77% in HPV-unrelated disease (n=22), CR 14%.
🔹 Iza-bren (EGFR×HER3 bispecific ADC) + pembrolizumab: ORR 58–63% across two dose cohorts, mDoR 13.6–17.8 months.
Two different approaches to EGFR targeting: dual receptor blockade versus dual targeting + cytotoxic payload delivery.
Key questions:
🔬 How do HPV status, PD-L1 CPS and EGFR/MET/HER3 expression influence benefit?
🔬 What is the incremental contribution of each component?
🔬 Can we identify who needs an ADC payload versus receptor blockade alone?
Promising early signals, but small cohorts, different populations and no head-to-head comparisons.
The next challenge is moving beyond response rates towards biomarker-guided treatment selection.

A very unexpected recognition from #ESMO26 🙏
Named a Top KOL Voice in #Melanoma alongside people I’ve learned from for years.
I’m still young, early in my career, and very aware of how much I have left to learn. But I’ve discovered that one of the best ways to learn oncology is to communicate it: read the study, question the methodology, challenge the conclusions, discuss it with colleagues…and try to explain why it actually matters!
Still learning. Just doing some of it out loud🗣️

One biomarker, three trials, three different answers. #Endometrialcancer at ESMO 2026.
#DUO_E: stage III to IV or recurrent, first line. Three arms, all with chemo: chemo alone, chemo + durvalumab, or chemo + durvalumab followed by durvalumab + olaparib maintenance. Both regimens beat chemo on PFS. Survival tells a different story by MMR status. dMMR: durvalumab drives the benefit, OS HR 0.57. Olaparib adds nothing, PFS HR 0.97. pMMR, 80% of patients: durvalumab alone, OS HR 0.95. Olaparib adds modest PFS, HR 0.76, no survival benefit shown, and grade ≥3 AEs rise from 26.8% to 49.5%. Olaparib was never formally tested against durvalumab alone. That comparison is exploratory.
#KEYNOTE_B21: after surgery, stage III to IVA, or stage I to II serous, clear cell or carcinosarcoma. Chemo ± pembro. Negative overall. dMMR 3-yr DSFS 95% vs 80%, large but descriptive.
#NRG_GY020: stage I to II endometrioid dMMR, high-intermediate risk. Radiation ± pembro. Negative, 73% vs 77%. 21% stopped pembro for toxicity.
My read: after surgery, pembro helps where risk is high and adds little where cure is already likely. In pMMR, we keep adding drugs and buying PFS, not survival. Olaparib is not the partner for IO in endometrial cancer. In ovarian, PARP inhibition rides on homologous recombination deficiency. More on the mechanism in a separate post.
How I will practice: 1- dMMR, advanced or high risk: IO in first line. 2- dMMR, early stage: radiation alone. 3-pMMR: I discuss olaparib honestly, a few months of PFS for real toxicity.
Molecular profile first, trials early.
Where I am putting my effort: the
pMMR, with ADCs and selection by tumor biology.#gyncsm #ESMO26 @myESMO
Slides: Vicky Makker's discussion, ESMO 2026.
Full UNION paper is out in Lancet Oncol. Supplement Table S4 caught my eye: median time from RT start to surgery was 72 vs 113 days (SCRT/IO vs control), yet pCR was 39.8% vs 15.3%.
I would've expected LOWER pCR with surgery that much sooner(!), as we've seen in past short-course RT trials. Makes that response signal even more interesting!
Adding ICI in rectal cancer sure seems enticing! Are we entering a new frontier?!?
---
#ASTRO26 STELLAR II (Li): phase 2/3, 588 pts w/ pMMR LARC, SCRT 25/5 → CAPOX x4 +/- sintilimab. Adding sintilimab increased CR (pCR + cCR) from 27% → 52% (p<0.001). pCR among operated pts went from 19% → 42%. G3-4 toxicity also went up, 20% → 28%. Looking forward to the primary phase 3 endpoint, 3y DFS, which is still pending.
---
#ASTRO26 TORCH-iTNT (Wang) asks a different question: randomized phase II, pMMR LARC, CAPOX + toripalimab x6 w/ vs w/o SCRT 25/5. CR was 37% w/o RT → 62% w/ SCRT. IO in both arms here.
---
Unlike UNION, both ASTRO trials allowed watch-and-wait / organ preservation, so CR includes cCR. These aren't all pCR comparisons. Oh and of course standard caveat that cross trial comparisons are a sin.
UNION enrolled only surgery-intended pts, and both arms got just 2 cycles of consolidation chemo vs the 4-6 now recommended. I wonder how this compares w/ modern TNT, especially when organ preservation is the goal.

My vote for maddest new drug at ESMO: a tri-functional immune-activating fusion protein.
SIRPα inhibition — activates macrophages.
PD-L1 inhibition — reactivates T cells.
TGF-β inhibition — deplete fibrotic barrier surrounding tumors, for better T cell infiltration. https://t.co/sNKPDdTulF
PD(L)1-VEGF bispecifics are already beating PD1 inhibition alone in trials, so what's next?
This trial (BioNTech, DualityBio, BMS) adds a new B7-H3 ADC to a PDL1-VEGF bispecific, with potential synergy:
1) VEGF blockade: normalizes tumor vasculature, improves ADC delivery and T cell infiltration.
2) B7-H3 ADC: kills cancer cells, triggers immunogenic inflammation.
3) PDL1 blockade: releases immune suppression, allows T cells to exploit immune response induced by ADC.
Confirmed ORR up to 71% -- in immune-cold platinum-resistant ovarian cancer.
The broader, ongoing phase 2 includes colorectal cancer, pancreatic cancer and other tumor types.

Malheureusement, les essais cliniques ne donnent pas toujours les résultats espérés.
J’ai eu la chance de participer à l’étude internationale de phase III IROCAS (PRODIGE 52), à laquelle je croyais beaucoup, dont les résultats viennent d’être présentés à l’ #ESMO2026 et publié dans @Annals_Oncology
L’objectif était simple : améliorer les chances de guérison des patients opérés d’un cancer du côlon de stade III à haut risque de récidive.
Nous espérions qu’en ajoutant une troisième molécule de chimiothérapie, l’irinotécan, au traitement standard FOLFOX, nous pourrions guérir davantage de patients.
Malheureusement, ce n’est pas le cas.
Chez 795 patients, la survie sans récidive à 3 ans est quasiment identique :
➡️ 65,6 % avec FOLFIRINOX (3 molécules)
➡️ 66,3 % avec FOLFOX (2 molécules)
Et davantage de diarrhées sévères et de fatigue avec le FOLFIRINOX.
Une déception, évidemment, pour tous ceux qui ont participé à cet essai.
Mais c’est aussi cela, la recherche clinique : accepter que nos hypothèses soient parfois démenties par les résultats.
Faire plus ne signifie pas toujours faire mieux.
Et démontrer qu’un traitement plus lourd n’apporte pas de bénéfice, c’est aussi faire progresser la médecine.
Can ADCs replace chemotherapy in NSCLC? 🫁
Key message from #ESMO26:

🔹 OptiTROP-Lung04: Proof of potential.
🔹 ADC toxicity and dose optimisation remain critical.
🔹 OptiTROP-Lung06: Promising synergy with immunotherapy.

⚠️ Grade ≥3 TRAEs: 54% (Combo) vs 19% (Mono)
🔥 The PFS benefit of Combo was maintained even in the ultra-high PD-L1 (90-100%) subgroup (25.4 vs 7.1 months)
This is a game changer!!
45% durable ORRs at higher dose levels.
READY for prime time and will change early treatment lines.
As excited as when I first saw PD1 results in RCC.
This will transform front lines and cure more patients. https://t.co/ENyrFI7KyT

Personalized cancer vaccination is moving from concept to clinically meaningful signal.
INTerpath-001 is positive.
Dr. @MarioBalsaMD discusses pembrolizumab + personalized mRNA vaccine V940 in resected #Melanoma.
📊 2-year RFS: 82% vs 60%
HR 0.58
📊 DMFS: 88.5% vs 80.2%
HR 0.62
🎯 Why this matters: this is not simply another adjuvant immunotherapy study. It is a proof-of-concept that a patient-specific neoantigen vaccine can add meaningful disease-control benefit to PD-1 blockade.
For me, the next questions are even more important:
🧬 Who benefits most?
⏳ Will this translate into an OS advantage?
🔄 How should it be positioned relative to neoadjuvant immunotherapy?
🎯 Can biomarkers identify the patients who truly need this degree of personalization?
Excellent discussion by @MarioBalsaMD, building on important work from @ProfGLongMIA @jasonlukemd and the INTerpath-001 investigators.

DUO-E | ESMO 2026 — PFS PASSED. OS STILL AWAITS VERDICT!
Three-part analysis of advanced/recurrent endometrial cancer.
Part 1: Rationale, trial design & PFS benefit.
Part 2: Median OS 51.1 vs 39.6 months (HR 0.77). An 11.5-month numerical gain, but formal interim significance not reached.
Part 3: Does olaparib truly add value? Incremental PFS benefit, greater toxicity, but unproven additional OS benefit over durvalumab alone.
The clinical question: Is the added PFS worth the toxicity while final OS remains awaited?

How is the vaccine personalised? Scientists compare the patient’s tumour DNA with their normal DNA to identify cancer-specific changes. These inform a bespoke mRNA vaccine encoding up to 34 tumour-specific targets, designed to help T cells recognise and attack that patient’s cancer.
This is what makes these results so compelling: treatment designed around an individual cancer’s molecular signature, translating into meaningful clinical benefit. Eagerly awaiting the cardiac safety data in the full publication in @NEJM in November.

For the final act of CheckMate 8HW, we finally have the significant OS data the doubters have been asking for.
What happens when you have a great treatment and an even better one for a study (and almost everyone crosses over)? You have to wait a really, really long time for OS. Also, some thoughts on splitting the alpha I won’t get into here.
Nivo/ipi vs nivo alone vs chemo, MSI-H/dMMR mCRC. Final OS analysis.
Response rate 72% with nivo/ipi, 58% with nivo alone.
Median OS still not reached.
OS HR 0.66 for nivo/ipi over nivo, statistically significant.
77% of nivo/ipi patients alive at 5 years.
Three out of four patients alive at five years. In metastatic colorectal cancer. 🤯
Not even going to talk about the chemo arm. It's clearly worse, and there is never a time to give chemo in MSI-H unless someone has extreme, active autoimmune disease. “Debulking” is absolute nonsense.
Bottom line: the doubters got their OS. Nivo/ipi is the first-line standard for MSI-H mCRC.
Next steps: how do we decide length of therapy, and how do we manage oligometastatic progression?
#ESMO26 @OncoAlert @TheGutOncLab @OncoAlert
Longer follow up of LS-11 showed lenvatinib/belzutifan vs cabozantinib did not reach significant OS HR 0.85 (0.70-1.03). #ESMO26 Other endpoints of RR (54%) and DFS (HR 0.75) remain positive and impressive. TRAEs are 73% vs 66%. This is the most robust 2nd line strategy IMO, as many patients don’t make it to 3rd line. Nevertheless the lack of OS means other sequencing strategies seem reasonable. @DrDanielHeng @OncoAlert
More is not always better in 1L RCC! Presenting LITESPARK-012 Ph.III: adding belzutifan or CTLA-4 blockade to Pembro/Len failed to improve PFS or OS.

LITESPARK-12 tested Len/pem/bel (VEGF/PD1/HIF) vs Len/pem in 1st line RCC #ESMO26 (supported by a RII +ve PFS R2 @AlbigesL @crisuarez08). In the R3 both PFS and OS hasd HRs~1 with ⬆️ tox for triplets. Belzutifan doublets seem active so why do the triplets fail. It’s likely due to the increased toxic compromising dose intensity of the extremely active Len/pem (2 yr PFS). There seems a limit to tolerable drug intensity- triplets (COSMIC313 too) maybe a step too far. @OncoAlert @DrChoueiri

PFS-positive. But is that enough to change practice?
KEYNOTE-B49: after endocrine therapy in PD-L1 CPS ≥1 HR+/HER2− advanced breast cancer, pembrolizumab + chemotherapy met its primary PFS endpoint:
• Median PFS: 6.7 vs 6.0 months; HR 0.74
• Final OS: 21.0 vs 22.2 months; HR 1.04 — no significant improvement
• Grade ≥3 treatment-related AEs: 37.6% vs 32.7%
The PFS result is statistically positive. The clinical decision is harder.
Does this benefit justify adding immunotherapy for the broad CPS ≥1 population—or do we need better selection?

It was a great honour to present the results of the phase 3 INTerpath-001 clinical trial at the #ESMO26 Congress in Madrid.
This international trial included 1137 patients, across 157 sites, whose melanoma had been surgically removed, but who were at very high risk of it returning. The trial showed adding #intismeran autogene, an mRNA based individualised neoantigen therapy, to pembrolizumab reduced the risk of recurrence or death by 42%.
This is the first phase 3 study to show that a treatment built from the unique ‘fingerprint’ of a patient’s own tumour can reduce the risk of recurrence or death from cancer. That fingerprint is read by sequencing the tumour, then a ‘wanted poster’ of the cancer is made as mRNA, showing the immune system exactly what to look for and attack. Having succeeded in melanoma, this proof of concept could mark the beginning of a foundational shift in how we treat cancer.

WHAT IF THE NEXT CANCER VACCINE IS MADE FROM YOUR OWN TUMOR?
CANCER VACCINES MAY HAVE JUST ENTERED A NEW ERA!
At ESMO 2026 investigators presented Phase 3 results that could reshape how we prevent melanoma recurrence!
The INTerpath 001 trial enrolled 1137 patients with surgically removed high risk melanoma!
Researchers combined pembrolizumab with a personalized mRNA cancer vaccine called intismeran autogene!
THE RESULTS ARE REMARKABLE!
The relative risk of cancer recurrence or death fell by 42%!
At two years 82.2% of patients receiving the combination remained recurrence free compared with 70% receiving pembrolizumab alone!
The risk of distant metastasis or death also decreased by 38%!
But the most extraordinary part may not be the numbers!
IT IS THE BIOLOGY!
Every cancer carries a unique collection of mutations!
Some mutations produce abnormal proteins called neoantigens!
These molecular abnormalities can distinguish malignant cells from healthy tissue!
Investigators sequence the tumor and select up to 34 personalized neoantigens!
They then manufacture an individualized mRNA therapy designed to teach the immune system to recognize those targets!
Pembrolizumab helps release inhibitory brakes on T cells!
The vaccine attempts to teach those cells exactly what to attack!
Imagine treating cancer using a molecular fingerprint taken directly from the patient's own tumor!
THIS IS NOT YET A CURE!
Overall survival data remain immature!
The vaccine remains investigational!
Fever! Injection site reactions! Fatigue! Manufacturing time! And access must all be considered!
BUT HERE IS WHERE I WOULD TAKE THE SCIENCE NEXT!
Why wait until radiographic recurrence to discover that microscopic cancer survived?
Could circulating tumor DNA identify patients harboring molecular residual disease?
Could personalized vaccines be adapted when new resistant tumor clones emerge?
Could T cell receptor sequencing reveal which neoantigens generate durable immune memory?
Could we combine personalized vaccination with strategies that reverse T cell exhaustion?
And perhaps most importantly!
Could this approach extend beyond melanoma into pancreatic cancer! Lung cancer! And other malignancies with high recurrence rates?
I would propose a prospective trial combining personalized neoantigen vaccination with serial circulating tumor DNA and longitudinal T cell profiling!
We should test whether molecular clearance predicts durable remission and whether persistent molecular disease identifies patients needing additional treatment!
The next frontier should not simply be treating visible cancer!
It should be identifying and eliminating the microscopic disease that eventually causes relapse!
Congratulations to Professor Georgina Long and the international INTerpath 001 investigators!
The future of oncology may become increasingly individualized!
ONE PATIENT!
ONE TUMOR!
ONE MOLECULAR FINGERPRINT!
ONE IMMUNE SYSTEM TRAINED TO RECOGNIZE IT!
Could personalized cancer vaccines eventually transform cancer from a disease we repeatedly treat into one we prevent from returning?

🚨 Two major ARPI trials in high-risk localized prostate cancer, each adding a drug to standard local therapy 🧵 #ProstateCancer #RadOnc #pcsm https://t.co/bgjcc8ckZL
Today, the Phase 3 results of DeLLphi-305 (@AmgenOncology @AstraZeneca) were presented by @sands_jacob at #ESMO26.
DeLLphi-305 delivered an unprecedented OS improvement (21.1 vs 12.7 mo, HR 0.42) for patients receiving tarlatamab + durvalumab, compared to durvalumab alone, in 1L maintenance after chemoIO induction for ES-SCLC. Studies like these provide renewed hope.
However, this data brings forth multiple concerns regarding international access to care, interpretation of contribution of parts, patient selection, and sequencing.
1️⃣ Equitable access to cross-over: at time of POD, only 12.2% of ITT population in the durvalumab arm (34/278) and 18.9% (34/179) of those who received subsequent anti-cancer therapies had access to tarlatamab.
This speaks to the global need to expand access to this life-saving therapy, as DeLLphi-301 demonstrated this impact with accessibility promptly available here in the USA as early as May 2024. Yet, @SclcSMASHERS all over the world still do not have this option even at relapse.
2️⃣ Line of therapy: while attrition to 2L may be significant in some practices & highlights the need to maximize proactive support & early palliative care, is there clear evidence of synergy with ICI+DLL3 TCE to transform outcomes, or is the effect additive? Preclinical data suggested synergy with this combination approach.
However, within subgroup analyses of those receiving tarlatamab in subsequent treatment, particularly in the USA, it appears there is signal of additivity, given the nullification of OS benefit with DLL3 TCE cross-over (in those receiving it as 2nd LOT).
Outside of risk of attrition, what variables favor using tarlatamab in 1LM vs 2L? Is the NE biology still preserved? Is the function of the immune system equivalently preserved following <4 weeks post chemoIO with myelosuppression?
3️⃣ Patient selection: Stratification with effective predictive biomarkers are key to know who can avoid any intensification, as they may be a durable ICI responder to monotherapy ICI.
Who can we avoid tarlatamab every 2 weeks indefinitely? Who should receive lurbi + atezo? Or durva + tarla?
More translational SCLC based biomarkers, beyond DLL3, are clearly of high unmet need to guide strategies.
4️⃣ Sequencing: if we use tarlatamab+durvalumab in the 1LM, what’s next? At POD, what approved option remains? Lurbi remains approved in the 1LM, but not at relapse. I-DXd BLA was voluntarily withdrawn. Trials are key, but enrollment for most global studies is brisk, particularly in the USA where enrollment is ~20% or less of the total cohort.

#ESMO26 One of my favorite discussant. Dr @JordiRemon discusses early stage immunotherapy abstracts. Many options in the neoadjuvant and perioperative space, summarized beautifully. What is the value of adjuvant immunotherapy? Is receipt of adjuvant therapy a surrogate for fitness? #ESMOAmbassadors
🔬 Four important discussions from the final Presidential Sessions at #ESMO26!
💊 KEYNOTE-C93: Pembrolizumab monotherapy improved PFS in dMMR advanced or recurrent endometrial cancer, although the prespecified non-inferiority criterion was not met. An important step toward chemotherapy-free treatment.
🎯 Sacituzumab tirumotecan (sac-TMT): Impressive results in previously treated endometrial cancer, with improved PFS (7.2 vs 3.9 months) and OS (19.0 vs 12.1 months). ADCs are clearly changing the landscape!
🧬 MOIO trial: Can we safely extend immunotherapy intervals to every 3 months? The trial stopped early, leaving the question statistically unresolved and highlighting the challenges of treatment de-escalation.
📊 Non-inferiority: Who decides how much efficacy we can afford to lose? A great reminder that statistical margins must also reflect clinical judgment and patient preferences.
Four discussions that could shape how we design trials and treat patients in the coming years. 💚

Key takeaways on EGFR + MET TKI strategies:
▪️ SAFFRON (Osi + Savo vs Chemo): PFS 7.6 vs 5.4 mo (HR 0.55), OS 17.8 vs 12.9 mo (HR 0.68) post-3rd gen TKI.
▪️ SACHI (Osi + Savo): PFS 8.2 vs 4.5 mo (HR 0.34) | ORR 63% vs 36%.
▪️ MARIPOSA-2 Benchmarking: Ami-chemo gives PFS 8.3 vs 4.2 mo (HR 0.44), but without MET selection.
Dr. Heist highlighted critical open questions: defining optimal MET cutoffs, balancing oral vs IV regimens, and distinct AE profiles across combinations!

Tom Powles@tompowles1
The MOIO randomised phase 3 non-inferiority trial (n=340) explored early discontinuation of ICI therapy be SOC in advanced patients responding to therapy. It had many flaws (mixed tumors and treatments, small size, early discontinuation etc). Also, due to the statistics, it’s not possible to say whether non-inferiority was achieved (OS HR 1.89 [95%Cl: 1.03,3.48]). Despite these problems it highlights a concern around early discontinuation, which should be taken seriously. Tumour specific trials are needed, but I’m not sure it will be easy to randomize patients . #ESMO26 @OncoAlert @myESMO @Annals_Oncology

🔬 Four important discussions from the final Presidential Sessions at #ESMO26!
💊 KEYNOTE-C93: Pembrolizumab monotherapy improved PFS in dMMR advanced or recurrent endometrial cancer, although the prespecified non-inferiority criterion was not met. An important step toward chemotherapy-free treatment.
🎯 Sacituzumab tirumotecan (sac-TMT): Impressive results in previously treated endometrial cancer, with improved PFS (7.2 vs 3.9 months) and OS (19.0 vs 12.1 months). ADCs are clearly changing the landscape!
🧬 MOIO trial: Can we safely extend immunotherapy intervals to every 3 months? The trial stopped early, leaving the question statistically unresolved and highlighting the challenges of treatment de-escalation.
📊 Non-inferiority: Who decides how much efficacy we can afford to lose? A great reminder that statistical margins must also reflect clinical judgment and patient preferences.
Four discussions that could shape how we design trials and treat patients in the coming years. 💚

Every company developing G12X drugs should pay attention to this data at #ESMO26
Zecdarasib (G12Di) plus chemo in 1L metastatic PDAC, phase 1
ORR 89% with mFOLFIRINOX (n=27) ORR 69% with gem/nab-paclitaxel (n=26)
Awesome safety for early DE.
For context, other early 1L PDAC response rates (cross-trial which we would neeeeever do):
Zoldonrasib + FOLFIRINOX: 82% Zoldonrasib + gem/nab-P: 61% Daraxonrasib + gem/nab-P: 59% Daraxonrasib alone: 47%
Chemo clearly still matters. Starting to think about this like Breakwater…
In PDAC, monoallelic inhibitors are extremely effective, just more effective with a little extra oomph behind them.
They will land in adjuvant, neoadjuvant, metastatic and every space you can imagine in the next few years.
Question is do we combo single plus pan or single plus chemo, and what is the added agent (especially in CRC)?

MOIO at #ESMO26: 12-week vs standard ICI in patients responding at 6 months. Stopped early, futility bar not crossed.
📉 mITT PFS HR 1.35, median 21.9 vs 25.0 months
⚠️ OS HR 2.04 (1.08 to 3.85), 31 vs 16 deaths (stopped by DSMC)
🧪 UC PFS HR 2.91 (1.27 to 6.67), RCC 0.68 (0.32 to 1.44).
Hypothesis-generating. No safety advantage. Results can't support 12-week dosing in responders. Congrats on this huge effort, inferiority trials hard to run, pragmatic trial to better understand schedule of IO therapy.

TroFuse-005/GOG-3095 (Lorusso, #ESMO26): Options after carbo/paclitaxel/ICI in recurrent endometrial cancer are limited and poor. Sac-TMT is the first TOP1 ADC to read out positive in phase 3: PFS HR 0.59 (7.2 vs 3.9 mo), ORR 35% vs 17%, plus an OS benefit. That is clinically meaningful and warrants use.
The tox is a concern. Stomatitis 57% (mostly low grade, needs prophylactic steroid mouthwash), ocular 31%, anemia 71%. Requires aggressive counseling and mitigation. Several other ADCs are in phase 3, and I hope they match this efficacy with better tolerability. Time will tell. @myESMO
#ESMO26: Another flawless discussion by @JordiRemon on the perioperative IO session:
✅ 5 trials with reported OS benefit of a periop approach
❌ Biomarkers: PDL1 suboptimal and inconsistent, TMB prognostic, without defined cutoff, TcellGEP sign prognostic
❓ Still the question of the contribution of adjuvant component remains, de-escalation/ intensification trials ongoing
#ESMOAmbassadors
🚨 3rd Presidential Session at #ESMO26!
💉 Can we safely reduce the frequency of immunotherapy in advanced solid cancers?
The phase III MOIO trial tested 12-weekly versus standard immune checkpoint inhibitor administration in responding patients.
⚠️ Unexpected and concerning results!
📉 PFS: HR 1.35 (96.16% CI 0.90–2.04)
🚨 OS: HR 2.04 (95% CI 1.08–3.85), favouring standard treatment!
The trial stopped enrolment early following an unexpected OS imbalance.
A superb and thought-provoking discussion by @DrJNaidoo
Her key messages:
-Statistically inconclusive , but clinically reassuring? Certainly not!
-Non-inferiority margins matter! Would we really be comfortable accepting a potential 30% increase in the hazard of progression simply to reduce treatment frequency?
-One size does not fit all! Different tumour types, different immunotherapy regimens, different biology. Can a pan-tumour de-escalation strategy really work?
-Pragmatic does not mean compromising scientific rigour.
The take-home message: De-escalation remains an important goal, but it must be biologically justified, clinically meaningful and supported by robust evidence.
Doing less is only progress if we can demonstrate that patients are not paying the price in efficacy or survival.
👏 Congratulations to @DrJNaidoo for an outstanding discussion!
#ESMO26 #ESMOAmbassadors #Immunotherapy #MOIO #DeEscalation #Oncology
What an elegant discuss. for a negative trial. Managed to contextualize, compare trial designs, and, even when considering worsening HRs when using IO only for 3 months, @DrJNaidoo managed to be quite hopeful on how future IO trials, for de-escalation, are to be designed. #ESMO26 https://t.co/VW8da7Dwoy

@DrJNaidoo : Excellent job summarising the MOIO data and asking key questions. Heterogenous population and choice of endpoints perhaps not ideal. Who defines non-inferiority? Can we use biomarkers? Are there better designs? A brilliant, thought provoking discussion, #LCSM #ESMO26 https://t.co/h6Yp1kbjh4
In pancreatic cancer, surgery is the only real chance of cure, and most patients never get there, because of distant metastases or the tumor is wrapped around vessels that can't be removed.
This trial from China tried shrinking it out of the way first, with a KRAS drug AND immunotherapy before the operation.
In the group that also got immunotherapy, 97% reached surgery, and every surgery removed the tumour completely with clear margins.
Usual caveats: It’s a small trial of 30 per group with no control arm, no reportable survival data yet, and as far as I know Chinese data from one hospital.
But this is the first KRAS data in the curable setting in this era. More trials are needed to confirm this early signal, but it’s only a matter of when, not if, that KRAS inhibitors also improve the curative setting. A lot of trials including with daraxonrasib are already running.
#ESMO26 Dr. Jarushka Naidoo @DrJNaidoo with a fantastic discussion on de-escalation trials in oncology. A call out on why de-escalation studies are important and their limitations. And for MOIO in particular - lessons on trial design, non-inferiority, and pragmatism. A must-listen to all involved in trial design. #ESMOAmbassadors
Gravis: MOIO study looking to show that reduced frequency IO is non-inferior to SoC. Non-inferiority not met. Study stopped early because reduced IO did not reduce toxicity or appear to improve survival. Pragmatic but messy design and small numbers. #LCSM #ESMO26 https://t.co/0qh2ZCBLvK

A new standard of care arrives in advanced KRAS G12C NSCLC: Divarasib (Krascendo-1)
🔸 Global, randomised, phase 3
🔸 Compared to current KRASi (mainly sotorasib)
🔺 No cross-over
What do we know so far?
🔹 2L sotorasib or adagrasib show modest PFS benefit vs docetaxel, but no OS benefit
What did we see at #ESMO26?
✅ Improved PFS, 9.8 v 4.7m: HR 0.58
✅ Improved ORR, 58% v 32%
✅ Improved OS, 17.7m v 12m: HR 0.56
⚠️ Lower Gr3+ AEs, but more Gr1-2 AEs - especially GI
What does this mean?
❗️New standard of care for KRAS G12C
✅ Clearly superior to current options
🤔 Need QoL & PRO data
🤔 Need intra-cranial activity data
⚠️ Side effects remain an issue, albeit lower grade (Gr2 diarrhoea is still pretty miserable)
❗️Drug access will be the main issue, especially with Sotorasib withdrawal of funding in many countries
🤔 1L, in combination with other agents, likely to be ultimate place for this drug

#ESMO26 Some very important points brought up by Dr. @JordiRemon on the real value of adjuvant immunotherapy for resected NSCLC. What is the value of improving DFS without OS benefit? Neoadjuvant approach much clearer but perhaps we need to develop smarter.
Happy Birthday to Dr. Remon!!
#ESMO26 One of my favorite discussant. Dr @JordiRemon discusses early stage immunotherapy abstracts. Many options in the neoadjuvant and perioperative space, summarized beautifully. What is the value of adjuvant immunotherapy? Is receipt of adjuvant therapy a surrogate for fitness? #ESMOAmbassadors
CLARITY-Gastric01 at #ESMO2026: a significant overall survival benefit with sonesitatug vedotin (Sone-Ve), a CLDN18.2-targeted ADC, in previously treated advanced gastroesophageal cancer.
This global phase III trial compared Sone-Ve with investigator’s choice of therapy:
• Third line and beyond: Median OS 10.0 vs 5.0 months, HR 0.47 (95% CI 0.36–0.62), meeting the primary OS endpoint.
• Overall second-line-and-beyond population: Median OS 10.6 vs 6.4 months, HR 0.58 (95% CI 0.47–0.73), a key secondary endpoint.
• PFS by blinded central review did not reach statistical significance: 4.2 vs 3.8 months, HR 0.77. Understanding the OS–PFS discordance remains important.
• Safety: Grade ≥3 treatment-related adverse events occurred in 36.4% vs 44.8%, although grade ≥3 gastrointestinal toxicity was higher with Sone-Ve: 11.1% vs 6.3%.
Testing thresholds matter: Enrollment required CLDN18.2 membranous staining in ≥25% of tumor cells at any intensity, making it much broader. Zolbetuximab eligibility uses ≥75% with moderate-to-strong staining. “CLDN18.2-positive” needs an assay-specific, treatment-specific definition.

🔥 CLARITY-Gastric01 - Phase 3 (AstraZeneca release, ESMO LBA7)
🎯 Previously treated (≥2L) CLDN18.2+ gastric, GEJ or oesophageal adenocarcinoma
- How positive, you may ask? Not the usual 75%, but rather 25% expression.
💊 Sonesitatug vedotin (CLDN18.2 ADC) vs investigator's choice
👥 532 patients
✅ 3L+ OS 10.0 vs 5.0 mo, HR 0.47
✅ ITT OS 10.6 vs 6.4 mo, HR 0.58
➖ PFS co-primary missed, HR 0.77, p=0.053
⚠️ 2L-only OS HR 0.88, CI crosses 1
⚠️ Prior zolbetuximab exposure, if any, not reported
In 3L+, mOS doubles from 5 to 10 months, in a population defined at 25% CLDN18.2 expression, far broader than the zolbetuximab cut-off.
Now read the second line carefully: PFS missed, and the second-line OS HR was 0.88 with a CI crossing 1, so the ITT result leans on later lines.
Let’s please approve this already, at least for 3L. 🙏 But wait!! What can be said about patients with prior exposure to zolbetuximab ???
Also, G-HOPE-001 (see below), selected patients at a much stricter threshold (2+ in 75% or more), so do not compare the hazard ratios head to head. The open question for both ADCs is activity after first-line zolbetuximab.

Tarlatamab-durvalumab maintenance by Perol and @sands_jacob @NEJM for ES-SCLC discussed by @StephenVLiu at @myESMO
Take: DeLLphi-305, phase 3, n=563, maintenance after 1L chemoimmunotherapy without progression. Median OS 21.1 vs 12.7 months (HR 0.42, P<0.001). Median PFS 7.4 vs 1.9 months (HR 0.34). 12-month OS 79.4% vs 53.3%. Grade ≥3 events 46.8% vs 40.6%; CRS, mainly grade 1-2, in nearly half the tarlatamab arm.
As expected D-305 moves tarla into first-line maintenance and nearly doubles median survival in a disease where 12-13 months has been the ceiling for years. If we are honest, unless we make big change due to CRS and tocilizumab it will be hard to make tarlatamab mainstream to most patients even in the US and LMICs.

🔥 Outstanding piece of work published today in Nature Medicine!
Huge congratulations to @MartinReck2 ,@NadalErnest , @DoctorJSpicer and @AndrearicFili , and the entire MDT-BRIDGE team on this important publication! 👏👏
The phase II MDT-BRIDGE trial, investigating neoadjuvant durvalumab plus chemotherapy in resectable or borderline resectable NSCLC, tackles a clinically relevant question: how can we push the boundaries of multidisciplinary treatment and offer more patients a chance of curative-intent therapy?
This is exactly the kind of collaborative clinical research we need: challenging established boundaries, asking meaningful questions, and ultimately striving to improve outcomes for our patients.
Congratulations to everyone involved! 👏

Mali Barbi, MD MSc | Breast & Gyn Oncologist@DrBarbiOnc
Why does T-DXd stop working? Paired biopsies before and after ADCs, presented by @PTarantinoMD at ESMO 2026, give a clear first answer: the tumor rarely loses HER2.
Instead, several mechanisms coexist in the same tumor: Drug pumps up: ABCB1 rose in 5 of 7 T-DXd-treated tumors, ABCC1 in 4 of 7. Uptake down: MAN2A2, a glycosylation enzyme, fell in 5 of 7. In cell models, silencing it reduced T-DXd binding and internalization. After sacituzumab, no recurrent pattern at all.
For clinic: a repeat biopsy that only re-checks HER2 will usually come back "still positive" and explain nothing. The resistance happens after the drug reaches the cell.
Seven patients, hypothesis-generating. But it tells us what the next biopsy should measure. #bcsm #ESMO26
@myESMO
Congrats to Reck, Spicer, Filippi and team on the full MDT-BRIDGE paper in Nature Medicine! Really appreciate seeing the RT protocol and full denominators alongside the ASTRO results. 👏
This single-arm ph2 enrolled 142 pts with resectable or borderline-resectable stage IIB-selected IIIB, EGFR/ALK-wt NSCLC. Durvalumab + platinum chemo x2c→ MDT reassessment→ additional chemoimmunotherapy and surgery, or CRT, followed by durvalumab.
Resection was 74.6% (95CI 66.7-81.6), with R0 in 96.2% of those who started surgery. pCR was 27.3% in the resectable analysis cohort. The 12-mo EFS estimates are 88.5% overall and 90.1% in that resectable cohort. Different denominators, same readout.
The RT protocol details are useful: nominal 60/30 (60 Gy ±10% in 2 Gy fx), 5 fx/wk for ~6 wk, concurrent or sequential platinum chemo. SBRT was not allowed. IMRT with daily CBCT was preferred, then consolidation durvalumab q4w up to 12c.
All 25 pts who started CRT completed it: 21 concurrent, 4 sequential. 23 received consolidation durvalumab. The post hoc CRT-treated analysis estimated 12-mo PFS at 85% (95CI 59.8-95.0), measured from the FIRST study-treatment dose, including induction.
CRT-period G3/4 AEs were 28%; pneumonitis 8% (2 pts, both G2). During consolidation, G3/4 AEs were 17.4%, AE discontinuation 13%, and pneumonitis 8.7% (G1/2). One cardiac-failure AE death occurred during consolidation; the paper reports no treatment-related AE deaths in that period. The safety windows extend beyond treatment delivery and can overlap.
The ESMO ctDNA analysis adds an interesting association. Pre-Sx/CRT clearance occurred in 33/90 evaluable pts (36.7%). C2D1 clearance had an 83.3% PPV for pCR (95CI 43.6-99.1).
Among resected pts, no EFS events occurred with pre-Sx clearance (n=28); 12-mo EFS without clearance was 88.9% (n=40). In CRT-treated pts, 12-mo PFS was 100% with pre-CRT clearance vs 77.5% without. The paper now supplies those subgroup sizes: just 4 vs 16 pts, with 2 vs 6 at risk at 12 mo. One later event occurred in the clearance group, so 100% is a timepoint estimate, not no events throughout follow-up.
Useful prospective evidence that patients can reach definitive CRT after starting on a surgical pathway. The unanswered question remains who benefits from that sequence versus going directly to CRT or selecting for NAC-ICO with intent for organ preservation. Selected cohorts, immature EFS/PFS and no reported OS cannot settle that, and ctDNA does not yet tell us which local therapy to choose or omit.

How long should we continue anti-HER2 therapy in long-term responders? Can ctDNA help answer this?
Among 37 evaluable patients with HER2+ advanced breast cancer responding for ≥2 years, 81% remained persistently ctDNA-negative; 86% were negative at final assessment, including all 23 without radiological residual disease.
At 17.8 months’ median follow-up, 29/30 persistently negative patients remained progression-free.
Encouraging support for ctDNA-guided de-escalation trials; safe treatment discontinuation still needs to be demonstrated.

#ESMO26 | Bulumtatug fuvedotin
An important phase II study for ADC-after-ADC sequencing. In metastatic TNBC previously treated with Topo-I ADCs, this Nectin-4–targeted ADC carrying an MMAE payload achieved a 30% response rate.
Switching to a payload with limited cross-resistance may be key. Here, however, both target and payload changed, so the activity may reflect their combined contribution.
Switching ADC target does not work. Switching payload does.
Among 60 TOPO1-ADC-pretreated patients with MBC, using a microtubule (MMAE) ADC led to 30% ORR and DoR of 8.8 mo. #ESMO26 #ESMOAmbassadors https://t.co/uctYMRwtEx

It's understandable why oncologists and patients want crossover, and it's easy to argue for it after a positive trial. But when the trial was designed, no one knew divarasib would win, and G12Ci after G12Ci was unproven. Crossover makes sense when the later-line benefit is already established.
Anyone interested in cancer medicine needs to see the current front page of @NEJM

It's one historic advance after another after another on there right now https://t.co/twlEoVkqQO
This one bothers me. When SAFFRON opened in Aug 2022 there was real equipoise, savo + osi only had single arm data and chemo was the post-osi standard.
That changed in June 2025 when SACHI, a randomized phase 3 of the same combo, showed a big PFS benefit over chemo and China approved it. I can see the case for SAFFRON continuing to randomize, SACHI was China only and mostly after 1st or 2nd gen TKIs.
I can't see the case for still denying chemo pts the combo once they progressed. Every one of them got in because a biopsy showed MET-driven resistance, and outside China savo was essentially unavailable. That includes pts randomized before June 2025 who progressed after it. SACHI, same combo and same PI, let chemo pts cross over and 43% did.
KRYSTAL-12 allowed crossover to adagrasib, and GEOMETRY-E, capmatinib + osi in this same setting, added it by amendment.
No SAFFRON amendment adding crossover has been reported, and that likely made the OS gap bigger than it would have been with MET-directed therapy available after chemo.
PE-PE is a fantastic study, giving us randomized data on adding pembrolizumab to MDT in oligometastatic RCC!
Phase II, open-label, multicenter trial: 85 pts with prior nephrectomy and ≤3 mets within 5y of nephrectomy or previous metastasectomy, all amenable to surgery or SABR. Randomized 2:1 favoring pembro: MDT alone (n=29) vs pembro + MDT (n=56).
Pembro 400 mg q6w x9c (1y). First dose BEFORE MDT; registry specifies MDT on C1d21-42.
At MFU 17.5 mo, median RFS was 11→ 25.4 mo (HR 0.47, 95CI 0.24-0.92, p=0.024), MDT alone→ pembro + MDT. 35 RFS events, 16→ 19.
SABR 72→ 73%; surgery 28→ 23%. SABR dose/fx and per-site data weren't reported. I'd like to see those details along with local vs distant relapse.
Any AE 21→ 80%; G3 AEs 3→ 7%. The 21% control rate is with no study systemic therapy. Pembro-related AEs occurred in 59%, including G3 in 2 pts; no G4/5 pembro-related events were reported. Four pts stopped pembro for AEs.
Both groups received MDT, so the randomized question is what pembro adds. This doesn't establish the benefit of MDT itself or RT-ICI synergy. With 1 death/arm and no QoL results reported, an OS/QoL benefit remains unestablished.
I'd also like the prior systemic therapy history and the timing/burden at first metastatic presentation. The eligibility window alone doesn't tell us whether these pts were oligometastatic from the outset.
Congratulations to the investigators on this important work!

Four important studies from #ESMO26 today:
1. Endometrial cancer (Lancet): Sacituzumab tirumotecan (TROP2-targeted ADC) improved median overall survival from 12.1 to 19 months after prior chemotherapy and immunotherapy.
2. dMMR endometrial cancer (Lancet): First-line pembrolizumab alone improved median PFS (time without progression) from 8.4 to 38.2 months vs chemotherapy alone. A promising chemo-free option, although chemo plus immunotherapy remains the current standard.
3. Osteosarcoma (ARTEMIS-011): Risvutatug rezetecan (B7-H3-targeted ADC) improved median PFS from 1.4 to 5.5 months vs chemotherapy in heavily pretreated patients, including adolescents. A rare positive phase 3 trial in this disease.
4. An important caution (MOIO): In patients whose advanced cancer was responding after 6 months of immunotherapy, extending treatment intervals to every 12 weeks was unexpectedly associated with higher observed mortality (19.9% vs 10.5%) compared with standard dosing. The phase 3 trial was stopped early.
Important advances, but also a reminder that less treatment is not always better.
My *practice changing* take home messages from #ESMO26 to NHS lung cancer teams:
Immediate change:
1. PERSEE. Bottom line - Chemo still alive for PDL1 >50%. Median OS 50.2m Vs 29.9m. Works just as well for 90-100% group too
Fitter, younger should get Chemo even PDL1 100%
#ESMO26
A lot of new data on 2L post-EGFR TKI NSCLC treatment options in #ESMO26. What can we make of it all?
OptiTROP-Lung04:
👉 Sacituzumab-TMT (TROP2 ADC) vs. chemo
🔹 China-only, Ph3, randomised, open-label
✅ Previously positive PFS (ESMO 2025)
✅ Improved OS, 25.9 v 17.4m: HR 0.69
⚠️ Similar TRAEs, slightly more Gr1-2 with Saci-TMT
SAFFRON:
👉 Adding Savolitinib to Osimertinib in MET over-expressing (OE) / amplified
🔹 Global, Ph3, randomised v chemo
✅ Improves mPFS 7.6m v 5.4m: HR 0.55
✅ Similar benefit for OE & amplified pts
✅ Improved OS 17.8m v 12.9m: HR 0.68
⚠️ Lower Gr3+ AEs (40% v 52%) but higher Gr1-2 toxicity - oedema as expected
PANKU-Lung01:
👉 Iza-Bren (EGFR x HER3 ADC) v chemo
🔹 China-only, Ph3, randomised
✅ Improved mPFS 11.7 v 5.7m: HR 0.40
✅ Improved ORR 60% v 34%
❓OS, immature
⚠️ Higher Gr3+ AEs (78% v 62%). Mainly myelosupression
⚠️ High dose interruption (53%) & reduction (60%)
⚠️ Needs GCSF prophylaxis
HERON-Lung01:
👉 Rus-Rez (HER3 ADC) v chemo
🔹 China-only, Ph3, randomised
✅ Improves mPFS, 8.3m v 5.4m: HR 0.47
❓OS, immature
⚠️ Similar Gr3+ TRAEs, but higher Gr-2 AEs. Mainly myelosupression
…and add to this current / other options:
🔸 Pemetrexed & carboplatin
🔸 COMPEL: Osimertinib + chemo
🔸 MARIPOSA-2: Amivantamab + chemo
🔸 HARMONi: Ivonescimab + chemo
🤯
So, how do we interpret this?
🤔 Extraordinary proliferation of 2L options. Impossible to know today which is best
🤔 China-only studies needs global validation, as EGFR population different to rest of world
🤔 A biomarker driven option (SAFFRON) appealing, although only minority of patients MET OE/amp
🤔 Arrival of active ADCs very welcome, but biomarkers needed to better select patients
🤔 ADCs not necessarily less toxic than chemo: perhaps no increase in Gr3+, but a lot of Gr1-2 AEs
🤔 What is available 2L will impact on what we choose in 1L. In turn, what we choose 1L may impact on what we can use 2L (e.g. different MET alterations with Ami/Laz)
Conclusions: hugely complex. Only answerable with longer follow up & global studies.
#LCSM
At #ESMO26, the discussion on molecular profiling in early-stage melanoma highlighted a fundamental principle of precision oncology: clinical actionability matters more than genomic complexity.
BRAF V600 remains the key actionable biomarker, guiding targeted therapeutic decisions in eligible patients.
While broad NGS may provide deeper biological insights, its routine use requires evidence of meaningful clinical utility.
More molecular data does not necessarily translate into better patient outcomes.

I was waiting for this one. Everyone treating #endometrialcancer needs to see it: sac-TMT should become our second line after chemo-IO.
#TroFuse_005 sac-TMT, a TROP2 ADC, vs doxorubicin or weekly paclitaxel, 776 patients. OS 19.0 vs 12.1 mo , 32% lower risk of death. PFS 7.2 vs 3.9 mo, HR 0.59. Response rate 35% vs 17%.
For years, the patient progressing after chemo-IO left my clinic with doxorubicin or weekly paclitaxel and short control. This is the first ADC to improve survival in that setting.

Melanomda UV hasarı yüzünden tümör hücresinde çok sayıda mutasyon birikiyor. Bu mutasyonlar normal hücrede bulunmayan yeni protein parçaları üretiyor, bunlara neoantijen diyoruz
Çıkarılan tümör dizileniyor, hastanın normal DNA'sıyla karşılaştırılıyor, bağışıklık sisteminin en iyi tanıyacağı 34'e kadar neoantijen seçiliyor
Bunları kodlayan mRNA sadece o hasta için üretiliyor. Kas içine yapılıyor, hücre bu parçaları üretip bağışıklık sistemine gösteriyor, T hücreleri vücutta kalmış olası tümör hücrelerini tanımayı öğreniyor
Pembrolizumab da T hücresinin üzerindeki PD-1 frenini kaldırıyor, ikisi birlikte veriliyor
Rakamlar (INTerpath-001, Faz 3, evre IIB-IV melanom, 1137 hasta)
Nüks ya da ölüm riski %42 azalmış (HR 0,58)
2 yılda nüksüz kalan oranı %70,0'dan %82,2'ye çıkmış
Uzak metastaz ya da ölüm riski %38 azalmış (HR 0,62)
3. derece ve üstü tedaviye bağlı yan etki %14,2'ye %13,4, pembrolizumab tek başına verilenle neredeyse aynı
Mekanizmayla çok uyumlu bir ayrıntı daha var
İlk 6 ayda iki grup arasında fark yok (HR 0,99), fayda 6. aydan sonra ortaya çıkıyor (HR 0,42). T hücre yanıtının oturması zaman alıyor
Eksik kısım genel sağkalım. Şu an HR 0,77 ama güven aralığı 0,45-1,31, anlamlılığa ulaşmadı, takip sürüyor
Üretim tarafı da kolay sayılmaz. Taranan 1749 hastanın 302'si yeterli tümör örneği olmadığı için çalışmaya alınamadı, ameliyattan ilk doza kadar ortanca 64 gün geçiyor
FDA değerlendirmesi de henüz bekleniyor
Son olarak, aylardır "mRNA kanser yapar" diye yazan hesaplar bu çalışmayı nasıl açıklayacak merak ediyorum
757 hastaya mRNA verildi, kanserin geri dönme riski düştü ve ilacın kendisine bağlı tek bir ölüm olmadı
Bunu turbo kanser anlatısının neresine koyacaklar??
I opened the paper behind your list (Kim et al., Biomarker Research 2025). The hazard ratios match. Let me explain, the way I'd explain it to a med student, why they can't carry the "mRNA turbo cancer" headline.
1. The same signal shows up without mRNA. The paper reports that cDNA vaccines, the adenovirus vector ones like AstraZeneca, were associated with higher thyroid, gastric, colorectal, lung and prostate cancer. mRNA was associated with thyroid, colorectal, lung and breast. Two platforms with completely different biology, almost the same list. A cause inside the mRNA vial can't explain a vaccine that has no mRNA in it.
2. The time window. Follow-up was 1 year. Lung, prostate, colorectal and breast cancers grow for years before they reach a size that can be diagnosed. A tumor diagnosed within months of a shot was most likely there before the shot.
3. Korea itself. Look at thyroid, the top HR on the list. Ahn, Kim and Welch showed in NEJM 2014 that Korea's thyroid cancer diagnosis rate in 2011 was 15 times the 1993 rate while thyroid cancer mortality stayed flat, more than 40,000 diagnoses a year against 300-400 deaths. That rise came from ultrasound screening. In a country where how often you're scanned decides how often thyroid cancer gets found, people who show up for vaccination are also the people who show up for checkups. More contact with the health system, more diagnoses. The database can't separate "more cancer" from "more cancer found."
4. Design. Retrospective insurance data. The authors don't claim causation. They write that further research is needed.
And one more data point on mRNA and cancer, from a randomized trial this time. In INTerpath-001, 757 melanoma patients received a personalized mRNA therapy on top of pembrolizumab. Risk of recurrence or death fell by 42% versus pembrolizumab alone (HR 0.58).
If mRNA drove cancer, how would it lower cancer recurrence in a randomized trial?
🧑🔬I recently posted data from G-HOPE-001 and CLARITY-Gastric01, two phase 3 trials evaluating their respective ADCs in previously treated CLDN18.2-positive gastric, GEJ, or esophageal adenocarcinoma.
🧐 Can you spot the differences between arcotatug tavatecan and sonesitatug vedotin?
Btw, pay attention to the interesting design trade-off between retaining versus silencing the antibody’s Fc region.
😲Non-Fc-silenced ADCs (sonesitatug vedotin): Because ADCC and CDC provide an additional mechanism of tumor-cell killing, this ADCs may retain activity even in tumors with lower levels of CLDN18.2 expression.
- Trade-off: Preserving Fc activity may also increase the potential for immune-mediated toxicity, particularly because normal gastric mucosa expresses CLDN18.2.
🤐Fc-silenced ADCs (arcotatug tavatecan): Without additional ADCC/CDC-mediated killing, the ADC depends more heavily on target binding, internalization, and intracellular payload release. As a result, higher levels of CLDN18.2 expression may be needed to achieve sufficient payload delivery and tumor-cell killing.

KEYNOTE-177 vs CheckMate 8HW: PD-1 alone or dual IO?
Two landmark trials reshaping first-line treatment of MSI-H/dMMR metastatic colorectal cancer.
🔹 KEYNOTE-177 (André et al.) — Pembrolizumab established chemotherapy-free PD-1 monotherapy, with durable responses and a favourable toxicity profile.
🔹 CheckMate 8HW (Lonardi et al.) — Nivolumab + ipilimumab demonstrated significant survival benefit, with 5-year OS of 77% in the first-line cohort and 74% versus 62% against nivolumab across treatment lines.
⚠️ 77% vs 54.8% is NOT a head-to-head comparison! Different populations, trial designs and biomarker assessment preclude claims of superiority.
The question now: Who truly needs dual IO, and who can do just as well with PD-1 monotherapy?

ESMO26: New vaccines. Better survival. Negative trials.
My takeaway: progress isn’t more treatment. It’s the right treatment, for the right patient, within reach.
@myESMO @OncoAlert @OpenMedicineHQ #ESMO26 https://t.co/YEfGPhKvEl
CAR-T cells - the engineered immune cells that can cure blood cancers - shrank tumours in 89% of patients with advanced liver cancer in a trial presented today at ESMO.
Unfortunately the success wasn’t durable: The cancer started growing again after about four months.
What happens here? A patient's own immune cells are engineered twice, once to recognise the tumor, once to ignore the signal solid tumors use to tell immune cells to stop. That signal is why CAR-T has failed outside blood cancers for a decade.
It seems to work initially: 36 patients, all having failed four prior treatments, 89% with shrinkage, amazing results. But not for long, now we wonder why.
My 3 theories:
1) The engineered cells don't last, they expand and do their work, but are cleared over time, so the cancer has open season again. And something always survives.
2) These immune cells recognise one specific marker, and not every tumor cell carries it. They might get rid of 89% of the mass and you've precisely selected for the cells that were invisible to the attack. So you select for the disease basically.
3) The stop signal is only one of several. The tumor also starves immune cells of glucose, floods them with waste, recruits suppressive cells, exhausts them. There are always escape routes.
There is an interesting signal there, again 89% is impressive, these patients had nothing left, and also months matter when you only have few.
But now we need a more durable response, and also: the technique is not scalable today for the short lived result. Financials and access do matter, so this needs to be addressed alongside a more durable effect.

Ooo, supportive care. Easy win for patients.
Looks like swapping olanzapine out for mirtazapine significantly reduces nausea. Relevant to every oncologist.
Randomized trial from India at #ESMO26. 120 chemo-naive patients starting highly emetogenic chemo, randomized 1:1. Both arms got fosaprepitant + palonosetron + dex. Fourth drug was mirtazapine 15 mg vs olanzapine 5 mg, days 1–4.
Mirtazapine vs olanzapine: Acute 78.5% vs 56.4%, p=0.01 Delayed 52.3% vs 25.5%, p=0.003 Overall 46.2% vs 21.8%, p=0.005

What were your highlights from ESMO 2026? https://t.co/JEg2kYYhDB
Cancer Vaccines: From Immune Activation to Durable Clinical Benefit
At #ESMO26, Prof. Juliane Walz highlighted five key principles shaping the future of therapeutic cancer vaccines:
1. Antigen selection: Immunopeptidomics can help identify clinically relevant tumor targets.
2. Timing matters: The adjuvant/MRD setting may offer the greatest opportunity for vaccine-induced immunity.
3. Better combinations: Novel adjuvants, checkpoint inhibitors, and bispecific antibodies may enhance T-cell responses.
4. Encouraging early data: In CLL, a personalized peptide vaccine induced T-cell responses in 95% of patients, with MRD reduction in 90%.
5. Toward personalization: Fusion-derived antigens and individualized vaccine platforms are opening new therapeutic possibilities.
The key question is no longer just whether cancer vaccines induce immunity, but whether that immunity translates into durable clinical benefit.

#ESMO26 | ADC Resistance??
Paired pre-treatment and post-progression biopsies from 26 patients: HER2 decreased after T-DXd but never disappeared completely; no consistent TROP2 reduction occurred after SG. Drug efflux transporters increased in >50% of patients.
A small yet valuable translational study. The implication: switching targets within the same payload class may not overcome resistance. Alongside new ADCs, we need greater focus on different payloads and resistance biology.
Great work @PTarantinoMD 👏👏
#ESMO26 is a wrap. A few thoughts.
It is a privilege to be an oncologist. To everyone who took the time to meet with me, lend their expertise or mentor me in some way: thank you. I am grateful. Also, to the patients who contributed their time, hope and lives to allow these studies to happen, thank you. This is what allows progress.
1. ESMO absolutely brought incredible advancements. So did China. This was the first global conference where the USA has clearly been dethroned as the de facto biomedical trial leader (5 of the 7 Presidential Symposium late-breakers focused on new drugs were Chinese developed). Chinese patients will be getting access to the latest biomedical advances, first.
2. The molecular era is here for KRAS. Expect it to come to early lines, in every tumor, fast. Expect sexy combos. (I am personally very excited about Genmab + Incyte's LGR5-EGFR + G12D but also think Verastem’s and RevMed’s G12D’s look great.)
3. Some advances look meaningful but are minor. PD1-VEGF beats PD1, but it wasn't compared to PD1 + VEGF. The benefit looks similar to adding bev (duh).
4. Cellular therapy is finally here for solid tumors. Get your systems ready now, it takes years to truly prepare. The 66% response rate for TezR (SL-28) across all-comer solid tumors blew my mind.
5. ADCs will hit CRC/GI quickly, and in a few years there will be many questions about sequencing. Please please please stop using the same payloads.
6. Medical education is more important than ever with how fast the field is moving. If anyone has advice on how @TheGutOncLab can disseminate information better (like the people at @OpenMedicineHQ and @OncoAlert do), please let me know.
Here's to next year. Already getting ready for @ASCO GI

1/4 We know geriatric assessment can help tailor cancer treatment in older adults. But tumour-specific, real-world data are still limited.

For those interested in the details: Presented by Georgina Long at ESMO 2026 (LBA1, Presidential Symposium). Full paper in NEJM on Nov 11. Trial: INTerpath-001, 1,137 patients with resected stage IIB-IV melanoma, randomized 2:1. Benefit emerged after month 6 (HR 0.99 before, 0.42 after). 24-month RFS 82% vs 70%
Imagine being told you have cancer. You undergo surgery, and your doctor says:
"We can make a personalized vaccine based on your tumor's unique mutations that may meaningfully reduce the risk of your cancer coming back."
Would you take it?
That's what a phase 3 trial in melanoma (skin cancer) showed at #ESMO26. Adding a personalized mRNA cancer vaccine (intismeran) to immunotherapy after surgery reduced the risk of recurrence or death by 42% (HR 0.58) compared with immunotherapy alone.
It is not yet known whether it extends survival, and the vaccine is not yet approved. But this is an exciting step toward truly personalized cancer treatment.

Can We Move From Vaccine-Induced Immune Responses to Predictable, Durable Clinical Benefit?
At #ESMO26, Prof. Patrick A. Ott reviewed a decade of progress in personalized neoantigen cancer vaccines and highlighted five key messages:
1. Clinical benefit: INTerpath-001 demonstrated improved recurrence-free survival with intismeran plus pembrolizumab in resected melanoma (HR 0.58).
2. Immune memory: Neoantigen vaccines can induce durable T-cell responses, immune memory, and epitope spreading.
3. Beyond melanoma: Early renal cell carcinoma studies show encouraging results, although randomized validation remains essential.
4. Current limitations: Vaccine-induced T-cell responses still recognize only a fraction of the selected neoantigens.
5. The next generation: Better neoantigen prediction, vaccine platforms, delivery systems, and immune adjuvants may improve clinical efficacy.
The next challenge is not simply generating immunity, but translating it into predictable and durable clinical benefit.

A pleasure to catch up with so many terrific people at #ESMO26! @tompowles1, @DrChoueiri, @FedefedeFri, @alshamsi2000, @DrYukselUrun, @ProfSyedHussain, @ErikaHamilton9, @jrgralow, @MatteoSantoniMD, @chadinabhan, @OncHahn, @TiansterZhang, @AnaVManana - and that's just skimming the surface! #Oncology truly takes a village & this meeting has brought so many drivers of progress under one roof!
IROCAS: PIII adjuvant mFOLFIRINOX vs mFOLFOX6 in high-risk stage III colon cancer, now in Annals of Oncology.
TLDR: Adding irinotecan did nothing (because it has never worked in the adjuvant setting)📉
Key Points • Adjuvant colon, pT4 and/or pN2 • mFOLFIRINOX vs mFOLFOX6, 12 cycles, n=795
Results • 3-yr DFS 65.6% vs 66.3%, HR 1.07 • 3-yr OS 91.2% vs 86.7%, HR 0.85 • Grade ≥3 AEs identical at 62% (little surprising, just more diarrhea and GCSF use)
Importantly, the DFS curves sit on top of each other.
Irinotecan doesn’t work in the adjuvant setting, which brings me to my next point, CIRCULATE-US 👀
The escalation arm is cooked.
I wonder if there is still equipoise to enroll there?
After this and DYNAMIC-III failed, do we have enough data? I guess OS is still immature here so there is a minuscule glimmer of hope?
ctDNA keeps getting better at finding the patients who need better treatments, the problem is we didn’t have them until recently.
My pitch? Let’s use the new meds, G12Xs, anti-HER2, ADCs with non-irinotecan payloads. We have to do better for our patients. No one should be reaching for Irinotecan as adjuvant in 2026.

Congrats @drchoueiri @danafarber on a very well delivered presentation, encompassing a lot of the data we need to understand the "why" (i.e., toxicity burden, discontinuation, etc.).
I personally think the next phase of 1L drug development with #kidneycancer (if we are to proceed with triplets) will have to involve agents with a wide therapeutic index so administration of Drug 3 does not cause delays/interruptions w Drug 1 + 2.
In this regard, hopeful for @SWOG #S2419 (#BIOFRONT) led by @PBarataMD, investigating IO-backbone +/- #MO03 (a live bacterial product). #ESMO26 @oncoalert @brian_rini @tompowles1

ESMO 2026 | A cautionary tale for immunotherapy de-escalation!
MOIO Trial (LBA10) – Phase III non-inferiority trial testing 3-monthly immunotherapy vs standard dosing in responding patients with advanced/metastatic cancer.
📊 Key results (N=308):
• Median PFS: 21.9 vs 25 months (reduced vs standard; HR 1.35)
• Risk of death: HR 2.0 (95% CI 1.1–3.9; p=0.0143) ⚠️
• PFS HR in urothelial cancer: 2.9
• Grade 3–4 immune-related AEs: 9.5% vs 10.5%
❌ Non-inferiority NOT demonstrated.
❌ No meaningful safety advantage.
⚠️ Signal of inferior survival with reduced-frequency IO.
💡 Take-home: Less frequent immunotherapy is not necessarily equally effective!
Important: These are interim results with relatively small numbers and heterogeneous tumour types.

What are the 3 biggest non-GI-cancer results of ESMO 2026?
1) A vaccine built for one person worked. You sequence a patient's melanoma and find the mutations unique to them, before you manufacture a vaccine for that individual. At two years together with immunotherapy, 82% had no recurrence versus 70% with immunotherapy alone. First time in 30 years of trying that a cancer vaccine has succeeded. Access and price will remain an issue going forward.
https://t.co/XTuRLoFqEm
2) A drug called tarlatamab, which basically handcuffs your immune cells to the cancer cells, so they finally recognize and kill them, moved into first line treatment for advanced small cell lung cancer.
This has to be the daraxonrasib-moment for the lung guys, finally some really meaningful progress in an otherwise dire disease with little success in the last decades. Huge!
3) The KRAS-revolution continues in lung cancer. A next generation G12C-inhibitor beat the older ones head-to-head in advanced and pretreated patients: 17.7 months median survival against 12. Next stop might be first line?
https://t.co/8EqVAh9blk
2026 has been a historic year for cancer patients and care across - especially very dire - diseases. Congratulations to everybody involved as well as all the patients participating in these trials. You have truly made a difference for everyone!
📊 HARMONi-GI1 - Phase 3 (Akeso release, ESMO LBA8)
🎯 First-line advanced biliary tract cancer, China
💊 Ivonescimab (PD-1/VEGF) + gem-cis vs durvalumab + gem-cis
👥 682 patients, interim analysis
✅ OS 14.9 vs 12.1 mo, HR 0.75
✅ PFS 8.4 vs 5.8 mo, HR 0.61
📈 ORR 53.8% vs 32.5%
🩸 Grade ≥3 bleeding 1.5% vs 1.8%
⚠️ China only, interim analysis
A head-to-head win over TOPAZ-1. The US ECOG-ACRIN trial will decide it for Western patients.
Potential new SOC? Yes, but:
⚠️ This is an interim analysis with immature follow-up. Median follow-up was 14.3 months, and the 18-month OS difference rests on few patients still at risk. TOPAZ-1's benefit grew with longer follow-up (HR 0.80 → 0.76 → 0.74 → 0.75). Durability needs to be confirmed in both directions.
⚠️ Post-progression treatment was imbalanced. Only 31.8% of the ivonescimab arm received further therapy vs 45.9% of controls. This would normally dilute an OS benefit, so the HR may be conservative. However, the reasons for the gap (clinical decline, toxicity, how the denominator was defined) need to be in the full report.
⚠️ Subsequent therapy differs from US practice. In the US, second-line care for BTC increasingly involves targeted agents for FGFR2, IDH1, HER2, and others. Whether a China-only OS result carries over depends partly on that downstream care. FDA has stressed that subsequent therapies must match US practice when OS is the endpoint

ESMO 2026: whats new in liver and bile duct cancer?
1) Engineered immune cells: Solid tumors defeat CAR-T by telling immune cells to stand down. These new cells in the trial presented were built to ignore that signal, and tumors shrank in 89% of patients with advanced liver cancer who'd failed four treatments.
The catch: unfortunately it lasted only about 4 months, which is not enough yet for a very expensive treatment. But the response rate is very impressive.
https://t.co/hPUU20JmeI
2) Way closer to the clinic is a trial in bile duct cancer: An antibody combined with chemo doing two jobs beat the current best treatment of chemo and immunotherapy on survival. First time that's ever happened. Though the trial ran entirely in China, so it needs confirming elsewhere.
https://t.co/nTcMDuo8oQ
The field is moving forward with new ideas stimulating the immune system to fight the cancer, in my opinion the most promising route for durable treatment success.
An important development in rectal cancer treatment. The Phase II AZUR-1 trial, published in Annals of Oncology, found that 68% of evaluable patients with dMMR/MSI-H locally advanced rectal cancer achieved a sustained clinical complete response for at least 12 months following dostarlimab immunotherapy alone, without surgery.
For selected patients, this raises the possibility of avoiding the considerable morbidity associated with chemotherapy, radiotherapy and rectal surgery. The results are encouraging, although longer follow-up and confirmatory evidence remain important. The FDA granted accelerated approval for this indication on 19 October.

How it works: tarlatamab is a "bispecific." One arm grabs DLL3, a flag on most small cell cancer cells. The other arm grabs a T cell. It physically pulls your own immune cell onto the tumor. Off-the-shelf, no custom manufacturing.
Progression-free: median 7.4 vs 1.9 months.
The trial: DeLLphi-305, 563 patients, NEJM and ESMO this week. After standard chemo plus immunotherapy: durvalumab alone vs durvalumab + tarlatamab as first-line maintenance.
Median survival: 21.1 vs 12.7 months.
Death risk: 58% lower (relative, HR 0.42).
One of the most rewarding moments in early phase drug development is “passing the baton” 🏃♀️

As #ESMO26 ends in Madrid, eight trials caught my attention from a radiation oncology perspective.
From treatment intensification to organ preservation, positive and negative results give us plenty to discuss at our MDT meetings.
My highlights below 👇
#RadOnc #SBRT https://t.co/IqszNOxeNe
ESMO 2026 - pancreatic cancer, all you need to know.
1) KRAS is finally druggable, which slammed the door open for a new era in treating this disease. This week, two drugs added to chemotherapy shrank tumors in 63–87% of patients, not just stabilization, numbers nobody has seen in this disease.
https://t.co/ZBfE4vIyYt
2) And one moved to where cure lives. Given before surgery, 97% of patients reached the operating table and every operation removed the tumor completely. Add immunotherapy to the mix and we might increase efficacy further.
https://t.co/HjQg049eL8
Caveats throughout: early-phase, small, survival data immature, much of it from single countries. But this means progress never seen in treating this disease.
3) Daraxonrasib was the very first drug to revolutionize pancreatic cancer care and we continue to learn. Very early data seem to indicate a better efficacy of daraxonrasib with KRAS-G12V mutations rather than the more common G12D. Which in turn makes combinations with a dedicated G12D inhibitor like zoldonrasib very promising. Data pending, we should know more next year.

LEAP-012 long-term overall survival results presented at ESMO 2026
In unresectable non-metastatic hepatocellular carcinoma, the addition of lenvatinib plus pembrolizumab to TACE improved progression-free survival (14.6 vs 10.2 months; HR 0.70) but did not demonstrate an overall survival benefit (40.4 vs 40.8 months; HR 0.98). Grade ≥3 treatment-related adverse events were substantially more frequent with the combination (72% vs 32%).
Median overall survival of approximately 40 months in both arms establishes a new benchmark for this population. These data raise important questions about the role of systemic therapy added to TACE in intermediate-stage disease.

ESMO 2026, what’s happening in stomach and oesophageal cancer?
1) Chemotherapy, delivered as a Trojan horse. Some of these tumors carry a protein called Claudin 18.2, a label healthy tissue keeps hidden. A new drug called sonevitatug-vedotin chains chemotherapy to an antibody that finds it. In patients who'd already run out of options, survival doubled: 10 months against 5.
https://t.co/ltarTXPe36
2) Some patients kept their stomach. In those with a broken DNA spell-checker, immunotherapy cleared the cancer in 62%, no operation needed. It is a rare occasion, but organ preservation is now an option for those patients, who qualify.
https://t.co/9POEVfEomO
Both start with a cheap test on a biopsy. Ask whether it's been done, it might change everything.
When ~1/2 of patients w/ #mTNBC never receive 2nd-line treatment, improved PFS & OS in previously treated patients is especially encouraging! Sac-TMT improved median OS from 9.9 to 14.7 months. More treatment options, more time, more hope! THIS is progress! 👏 #ESMO2026 #bcsm https://t.co/nIwkXabBIr

ESMO 2026: colorectal cancer, what was important?
1) Surgery became optional for a few. In the small group whose tumors have a broken DNA spell-checker, immunotherapy alone made the cancer vanish in 71%. Most needed no surgery, no chemo, no radiation at all. Approved by FDA last week.
https://t.co/NTu2CKVLuY
2) And for everyone else - the 19 in 20 without that feature - a Chinese trial added short-burst radiation plus immunotherapy to standard treatment. At three years, 91% were alive without recurrence, against 77% without immunotherapy and longer radiation.
https://t.co/NTu2CKVLuY
3) You associate KRAS most likely with pancreatic or also lung cancer where it made the headlines in the last months. But it is also very prominent in colorectal cancer, where we have seen the first data in combination with other targeted drugs after many lines of chemotherapy. Monotherapies won’t be enough here, but it’s the first sign of hope also in colorectal, way more to come!

KEYNOTE-C93 (#ESMO26 LBA12): Chemo-free first-line option in dMMR endometrial cancer?
In 299 patients with advanced/recurrent dMMR endometrial cancer:
Pembrolizumab monotherapy vs carboplatin + paclitaxel
• Median PFS: 38.2 vs 8.4 months | HR 0.57 (p=0.0002)
• 36-month OS: 70.7% vs 62.0% | HR 0.77 (not significant)
• Grade ≥3 TRAEs: 18.1% vs 50.7%
• Better quality of life with pembrolizumab
Strong PFS benefit and markedly lower toxicity with a chemo-free approach.
But OS not yet significant (high crossover in the chemo arm), and it was not compared to chemo + immunotherapy.
Would you offer pembrolizumab monotherapy as first-line for selected dMMR patients?

Mali Barbi, MD MSc | Breast & Gyn Oncologist@DrBarbiOnc
@GIMedOnc @PTarantinoMD Yes, and ESMO 2026 showed it could work: bulumtatug fuvedotin (nectin-4, MMAE payload) gave a 30% ORR in TNBC after a TOPO1 ADC. But efflux pumps can take MMAE too, so switching isn't 100%. Timing between ADCs may matter too.
TroFuse-005 (#ESMO26 LBA11): Practice-changing in endometrial cancer?
In patients with advanced/recurrent endometrial cancer (including carcinosarcoma) after platinum + PD-(L)1 (n=776):
sac-TMT (TROP2 ADC) vs doxorubicin or paclitaxel:
• Median PFS: 7.2 vs 3.9 months | HR 0.59 (p<0.0001)
• Median OS: 19.0 vs 12.1 months | HR 0.68 (p=0.0001)
• ORR: 35.1% vs 17.3%
First ADC to show dual PFS + OS benefit in this setting.
Grade ≥3 TRAEs higher (54.4% vs 41.4%), mainly anemia and stomatitis. Treatment-related deaths 0.8% in both arms.
A clear step forward, but how do we manage the toxicity and sequence it with other ADCs?
@myESMO @OncoAlert @DLorusso @Annals_Oncology
#ESMO26 #EndometrialCancer #ADC #TroFuse005 #GynOnc @oncodaily
Congratulations to the authors and also prize for ADCs most likely to be confused with each other - Ruzaltatug Rezetecan (EGFR mutant lung) and risvutatug rezetecan (sarcoma presidential at #ESMO2026 - Ruz Rez vs Ris Rez anyone? 😀 https://t.co/w1OmBwciNW
3 practice refinements after #ESMO26:
1. Always offer screening brain MRI at metastatic diagnosis (HER2+/TN) and offer 1L ADCs in case of BM
2. Consider adding tucatinib to HP after local therapy for brain-only PD while on 1L HP maintenance
3. Limit sequential TOPO1 ADCs
The PE-PE trial at #ESMO26: Adding pembrolizumab to metastasis-directed therapy in oligometastatic RCC improved median RFS (25.4 vs 11 months). OS benefit remains unproven, with higher toxicity. https://t.co/FMDlALqoTO
TURNING PAGES TUESDAY | ESMO 2026 SPECIAL EDITION
ESMO was dominated by solid tumours. But what should an Indian haemato-oncologist take home?
Five abstracts. Four themes. Myeloma and lymphoma in focus.
1️⃣ BELANTAMAB: MOVING EARLIER, DOSING DIFFERENTLY
Bela-DRd / BelaRd | 1454O–1455O
🔴 In transplant-ineligible newly diagnosed myeloma:
• Bela-DRd: MRD negativity in 13/16 evaluable patients.
• BelaRd: 24-month PFS of 74.9% in 42 patients treated at the recommended dose.
These small studies, including previously reported follow-up data, explore earlier BCMA targeting and longer belantamab dosing intervals.
🇮🇳 The question for India: can we preserve efficacy while reducing treatment burden? Frontline use remains investigational, and interval optimisation must retain appropriate eye monitoring.
2️⃣ GPRC5D: ANOTHER BISPECIFIC TO WATCH
LBL-034 | 1456O
🔴 Median PFS of 21.8 months in 41 patients at active doses. Responses in extramedullary disease and after prior BCMA-directed therapy are encouraging.
PFS remains immature; cross-trial comparisons cannot establish superiority.
🇮🇳 The relevance: more options for studying target switching and sequencing after BCMA exposure.
3️⃣ BTK INHIBITION IN FRONTLINE LYMPHOMA
🔴 Rocbrutinib + R-CHOP | 1457O
A phase Ib exploration of adding BTK inhibition to an established chemotherapy backbone.
🇮🇳 Worth following. Routine addition of a BTK inhibitor to R-CHOP requires stronger evidence.
4️⃣ CD20 TARGETING THROUGH AN ADC
🔴 TRS005 | 1458O
In transformed DLBCL, 14/28 evaluable patients responded; median PFS was 8.7 months.
🇮🇳 A potential future option, with comparative benefit, safety, availability and affordability still to establish.
🛎️ WHAT CHANGES IN OUR PRACTISE TODAY?
These findings strengthen the case for clinical trials, coordinated eye-care pathways and measuring the full cost of treatment- including travel, toxicity & caregiver time. They do not yet establish new routine regimens.
➡️ For India, the next breakthrough must be something patients can ACCESS, TOLERATE and SUSTAIN

Triplets in 1st line RCC failed in LS12 @Annals_Oncology @brian_rini (n=1500!). There are not many combinations with HIF/VEGF/PD1 left to test and this approach has probably run its course. It’s time for a new chapter in RCC with T cell engagers and bispecifics #ESMO26 @montypal @DrChoueiri @OncoAlert
Goodbye to #ESMO26! It feels like the pace of innovation is accelerating and it’s hard to keep up but wonderful for patients. Great to catch up with old friends, make new ones, and congrats to a stellar @bmsnews team for a strong showing in Madrid! https://t.co/YxV1kfHZb4

Lots of excitement #ESMO2026🇪🇸 for IO in
MSI-H CRC with NICHE-2 & AZUR-1
Some say it’s the end of surgery but I think it
has just taken on a different role as salvage tx
By definition you need an operation for pCR😉
Perhaps may even expand OR indications🤔
#adjuvantsurgery https://t.co/T3Zk7cxASC
I think pragmatic trial designs should match common sense of daily practice.
I guess most of us do not expect "3-months" when reduced frequency IO.
It is 2-week nivo to 3-week, 3-week pembro to 4-5 weeks etc..
Moreover I believe that patients also would not be comfortable with 3 months.
12-week is too long as a common sense. A criteria such as "50% or double increase frequency for each IO regimen" would be meaningful.
Solid tumour oncologists will now have to get used to tongue twisters like "Izalontamab Brengitecan" like heamtologists pronouncing "Axicabtagene ciloleucel"

☂️ 5 MORE YEARS OF LETROZOLE — WORTH IT?
NSABP B-42 | Final 15-year analysis | #ESMO2026
After 5 years of endocrine therapy:
• DFS: 61.6% vs 56.5% (HR 0.85)
• Distant recurrence: 6.9% vs 9.7% (HR 0.72)
• OS: No significant benefit (HR 0.92)
• No significant increase in fractures or arterial thrombotic events.
Fewer recurrences. No proven OS gain.
Extended endocrine therapy is an option — not a necessity for everyone.

NSABP B-42 | ESMO 2026 🎗️
5 MORE YEARS OF LETROZOLE — WORTH IT?
After 5 years of endocrine therapy, does extending letrozole improve outcomes in HR+ early breast cancer?
📉 Distant metastases at 15 years: 9.7% → 6.9% (HR 0.72)
✅ ~3 fewer distant recurrences per 100 women
❌ No significant overall survival benefit (HR 0.92)
💡 The lesson: Extended endocrine therapy is not for everyone. Individualize based on recurrence risk, bone health and tolerability.
FEWER RECURRENCES. NO PROVEN OS GAIN. EXTEND SELECTIVELY!

Surgical conversion after induction chemoimmunotherapy in CTONG 1804 part 3 (LBA65).
📌 Prospective, single-arm phase 2, 215 pts w/ stage III NSCLC. 196 unresectable; 19 potentially resectable at baseline MDT assessment.
📌 Induction chemoimmunotherapy → MDT reassessment → surgery in 105 (48.8%); CRT in 60 (27.9%).
📌 Median follow-up 31.3 mo. 12-mo EFS: 84.6% after surgery vs 66.7% after CRT; mEFS NR vs 20.5 mo.
📌 Among surgical pts: R0 98.1%; pCR 48.6%.
📌 2 treatment-related pneumonitis deaths during induction.
Side note: Surgery/CRT groups were selected after induction, so EFS isn't a randomized comparison. CRT had 16/30 events labeled 'Local'; the abstract doesn't define 'local' or clarify nodal involvement or in-field vs out-of-field failure. @DrewMoghanaki

We are all done with #ESMO26! 10+ studies that were on our radar and the updated data around them.
Out in the community settings, it’s tough to keep up with all that is happening here in the world of cancer (and this was just ONE conference).

2. MOIO: PhIII, non-inferiority of reduced-frequency (q3mo) vs standard IO in responders with advanced cancer
- PFS 25 vs 21.9 mo (HR 1.35) - Death HR 2.0 - No clear safety gain. This is disappointing to see. We need more guidance on who we can de-escalate IO for.
4. KEYNOTE-C93: PhIII, pembro mono vs carbo/paclitaxel in 1L dMMR advanced/recurrent endometrial ca
- mPFS 38.2 vs 8.4 mo (HR 0.57) - G≥3 TRAEs 18.1% vs 50.7% - DoR NR vs 10.2 mo - OS immature. IO/ICI regardless of aite, in dMMR, this remains the preferred backbone.

KEYNOTE-C93 | ESMO 2026 🔬
Can we skip chemotherapy in 1L dMMR endometrial cancer?
PFS: 38.2 vs 8.4 months (HR 0.57)
ORR: 64% vs 62%
Grade ≥3 TRAEs: 18% vs 51%
Similar response. Longer control. Less toxicity.
⚠️ OS not significant. Comparator was chemo alone, NOT chemo-IO.

@myESMO @OncoAlert @larvol #MVOnco
The MOIO trial sparked an important discussion on immunotherapy de-escalation and the challenges of non-inferiority trials. So many valuable insights!
It was a real pleasure to follow your excellent presentation in person, Dr. Naidoo. The room was packed, and the discussion was truly engaging! 👏 #ESMO26
Following up on our commentary on global validation for Chinese CPIs:
Presented at #ESMO26: The US randomized ASTRIDE study marks the first bridging trial to validate a Chinese anti-PD-1 CPI (serplulimab) in a US population! 🇺🇸
Key findings vs standard atezolizumab + chemo:
🔹 mOS: 12.4 vs 10.2 mo (HR 0.82)
🔹 24-mo OS: 32.2% vs 17.6%
🔹 Safety: Comparable profiles

💊 ADC SEQUENCING: TARGET OR PAYLOAD?
Does changing the ADC really change the weapon?
✅ Same target + different payload: T-DM1 → T-DXd
✅ Different target + different payload: EV → SG
⚠️ Different target + same payload class: T-DXd → SG
⚠️ Same target + same payload class: Dato-DXd → SG
🔬 DXd and SN-38 are different drugs, but both are TOP1 inhibitors.
🎯 Changing the TARGET ≠ changing the WEAPON!
SWITCH + SATEEN highlight potential payload cross-resistance. Sequencing remains context-dependent, not an absolute YES/NO rule.

What are the 3 biggest non-GI-cancer results of ESMO 2026?
1) A vaccine built for one person worked. You sequence a patient's melanoma and find the mutations unique to them, before you manufacture a vaccine for that individual. At two years together with immunotherapy, 82% had no recurrence versus 70% with immunotherapy alone. First time in 30 years of trying that a cancer vaccine has succeeded. Access and price will remain an issue going forward.

2) A drug called tarlatamab, which basically handcuffs your immune cells to the cancer cells, so they finally recognize and kill them, moved into first line treatment for advanced small cell lung cancer.
This has to be the daraxonrasib-moment for the lung guys, finally some really meaningful progress in an otherwise dire disease with little success in the last decades. Huge!
3) The KRAS-revolution continues in lung cancer. A next generation G12C-inhibitor beat the older ones head-to-head in advanced and pretreated patients: 17.7 months median survival against 12. Next stop might be first line?

2026 has been a historic year for cancer patients and care across - especially very dire - diseases. Congratulations to everybody involved as well as all the patients participating in these trials. You have truly made a difference for everyone!

Quoting the great @DavidHongMD - First in class is not always the best in class.
We will keep seeing this more often.
#ESMO26
When I qualified lung cancer was with small cell or non small cell. Now look - we’ve got 9 to 11 driver genes, and these commonly include EGFR, ALK, ROS1, BRAF V600E, MET, RET, KRAS G12C, HER2, NTRK, and NRG1(with at least 11 major mutations clinically targetable with specific agents!!!!

Interesting data from Phase 2 study #COMRADE at #ESMO26: Early on-treatment #ctDNA may help identify patients at risk of progression after just one cycle of #radium223. Possibly one more step toward biomarker-guided, adaptive radiopharmaceutical therapy.
We are getting more and more evidence about a potential key prognostic role of ctDNA also in #ProstateCancer including evidence that it may be used as a guide for treatment modulation - it will be most important now to prospectively include ctDNA in more trials and further validate it #mCRPC #RLT #Olaparib #radium223 @urotoday @oncodaily @OncoDailyGU @DrRanaMcKay
👏 Huge congratulations to my colleague @Maxime_Borgeaud for presenting his excellent poster on liquid biopsy in fusion-driven NSCLC at #ESMO26!
Great to see the results of his work at Gustave Roussy!
And on a personal note, I couldn’t be happier to welcome him back to Geneva @hug_ge after a fantastic year at Gustave Roussy!
Looking forward to having you back on the team, Maxime! 🚀

TURNING PAGES TUESDAY | ESMO 2026 SPECIAL EDITION
ESMO was dominated by solid tumours. But what should an Indian haemato-oncologist take home?
Five abstracts. Four themes. Myeloma and lymphoma in focus.
1️⃣ BELANTAMAB: MOVING EARLIER, DOSING DIFFERENTLY
Bela-DRd / BelaRd | 1454O–1455O
🔴 In transplant-ineligible newly diagnosed myeloma:
• Bela-DRd: MRD negativity in 13/16 evaluable patients.
• BelaRd: 24-month PFS of 74.9% in 42 patients treated at the recommended dose.
These small studies, including previously reported follow-up data, explore earlier BCMA targeting and longer belantamab dosing intervals.
🇮🇳 The question for India: can we preserve efficacy while reducing treatment burden? Frontline use remains investigational, and interval optimisation must retain appropriate eye monitoring.
2️⃣ GPRC5D: ANOTHER BISPECIFIC TO WATCH
LBL-034 | 1456O
🔴 Median PFS of 21.8 months in 41 patients at active doses. Responses in extramedullary disease and after prior BCMA-directed therapy are encouraging.
PFS remains immature; cross-trial comparisons cannot establish superiority.
🇮🇳 The relevance: more options for studying target switching and sequencing after BCMA exposure.
3️⃣ BTK INHIBITION IN FRONTLINE LYMPHOMA
🔴 Rocbrutinib + R-CHOP | 1457O
A phase Ib exploration of adding BTK inhibition to an established chemotherapy backbone.
🇮🇳 Worth following. Routine addition of a BTK inhibitor to R-CHOP requires stronger evidence.
4️⃣ CD20 TARGETING THROUGH AN ADC
🔴 TRS005 | 1458O
In transformed DLBCL, 14/28 evaluable patients responded; median PFS was 8.7 months.
🇮🇳 A potential future option, with comparative benefit, safety, availability and affordability still to establish.
🛎️ WHAT CHANGES IN OUR PRACTISE TODAY?
These findings strengthen the case for clinical trials, coordinated eye-care pathways and measuring the full cost of treatment- including travel, toxicity & caregiver time. They do not yet establish new routine regimens.
➡️ For India, the next breakthrough must be something patients can ACCESS, TOLERATE and SUSTAIN
#TurningPagesTuesday #LymSM #MMsm
HER2+ MBC with CR/PR ≥2 years, ctDNA monitored every 3 months.
81% remained ctDNA-negative without radiographic PD.
In all patients with baseline radiographic RD who progressed, ctDNA positivity preceded or coincided with PD.
🌅The era of ctDNA-guided trials is here.

📊 HARMONi-GI1 - Phase 3 (Akeso release, ESMO LBA8)
🎯 First-line advanced biliary tract cancer, China
💊 Ivonescimab (PD-1/VEGF) + gem-cis vs durvalumab + gem-cis
👥 682 patients, interim analysis
✅ OS 14.9 vs 12.1 mo, HR 0.75
✅ PFS 8.4 vs 5.8 mo, HR 0.61
📈 ORR 53.8% vs 32.5%
🩸 Grade ≥3 bleeding 1.5% vs 1.8%
⚠️ China only, interim analysis
A head-to-head win over TOPAZ-1. The US ECOG-ACRIN trial will decide it for Western patients.
Potential new SOC? Yes, but:
⚠️ This is an interim analysis with immature follow-up. Median follow-up was 14.3 months, and the 18-month OS difference rests on few patients still at risk. TOPAZ-1's benefit grew with longer follow-up (HR 0.80 → 0.76 → 0.74 → 0.75). Durability needs to be confirmed in both directions.
⚠️ Post-progression treatment was imbalanced. Only 31.8% of the ivonescimab arm received further therapy vs 45.9% of controls. This would normally dilute an OS benefit, so the HR may be conservative. However, the reasons for the gap (clinical decline, toxicity, how the denominator was defined) need to be in the full report.
⚠️ Subsequent therapy differs from US practice. In the US, second-line care for BTC increasingly involves targeted agents for FGFR2, IDH1, HER2, and others. Whether a China-only OS result carries over depends partly on that downstream care. FDA has stressed that subsequent therapies must match US practice when OS is the endpoint

An important development in rectal cancer treatment. The Phase II AZUR-1 trial, published in Annals of Oncology, found that 68% of evaluable patients with dMMR/MSI-H locally advanced rectal cancer achieved a sustained clinical complete response for at least 12 months following dostarlimab immunotherapy alone, without surgery.
For selected patients, this raises the possibility of avoiding the considerable morbidity associated with chemotherapy, radiotherapy and rectal surgery. The results are encouraging, although longer follow-up and confirmatory evidence remain important. The FDA granted accelerated approval for this indication on 19 October.

🚨 ASCO 2026: PARP inhibitors in ovarian cancer. What has changed?
The new ASCO Living Guideline, published in @JCO_ASCO, reviewed 31 pivotal trials and 13 HRD assays.
1️⃣ First-line maintenance: The preferred window for PARPi
🔹 SOLO-1: Olaparib established durable benefit in BRCA-mutated disease.
🔹 PRIMA / PRIME: Niraparib improved PFS, with the greatest benefit in HRD-positive disease.
🔹 ATHENA-MONO: Rucaparib demonstrated PFS benefit, particularly in HRD-positive tumors.
🔹 PAOLA-1: Olaparib + bevacizumab benefits patients with HRD-positive disease following platinum + bevacizumab.
2️⃣ Biomarker selection is critical
✅ BRCA-mutated or HRD-positive: Offer first-line PARPi maintenance after platinum response.
❌ BRCA-wild-type / HRD-negative: Not routinely recommended, despite modest PFS signals in PRIMA and ATHENA-MONO.
3️⃣ Recurrent ovarian cancer: A major restriction
🔹 SOLO-2 / NOVA / ARIEL3: PFS benefits established, but mature OS findings raised concerns in some subgroups.
➡️ Recurrent maintenance is now primarily reserved for PARPi-naïve, BRCA-mutated patients responding to platinum.
4️⃣ PARPi as treatment, not maintenance?
🔹 SOLO-3 / ARIEL4: Concerning OS findings altered the risk-benefit assessment.
❌ PARPi monotherapy is NOT recommended for treatment of recurrent ovarian cancer outside clinical trials.
5️⃣ What about PARPi rechallenge?
🔹 OReO / ENGOT-ov38: Modest PFS benefit, but insufficient evidence for routine PARPi rechallenge.
The clinical takeaway:
PARPi treatment is moving from broad use across multiple lines toward earlier, biomarker-selected maintenance.
The question is no longer simply “Is the patient platinum-sensitive?”
It is “BRCA? HRD? Prior PARPi exposure? Which line of therapy?”

Phase III bladder cancer trials at #ESMO26.
Different outcomes. Same question:
Progress isn’t more treatment.
It’s the right treatment, for the right patient, at the right time.
Can AI actually help us get there or are we still optimizing for “more”?

Proud to present our team’s latest research from @LurieCancer at #ESMO2026! 📊🤖
"Characterizing Hallucinations in Large Language Models (LLMs) Using Real-World Oncology Cases for Clinical Decision Support"
Key takeaways from evaluating LLMs on 20 first-line NSCLC cases against NCCN Guidelines:
💡 High Accuracy ≠ Clinical Safety: Even top-performing models exhibit clinically significant hallucinations, emphasizing that high accuracy does not guarantee hallucination-free outputs.
💡 High Confidence Risks: Confident but incorrect responses pose critical risks to clinical decision-making, requiring strict human oversight.
💡 Input-Length Dynamics: The impact of input length on accuracy varies widely across models—longer inputs correlated positively in some models, but negatively in others.
Huge thanks to lead author Dr. Jiyon Lyu,, and all co-authors for this impactful work on AI safety in oncology! 🩺👏

ESMO 2026: whats new in liver and bile duct cancer?
1) Engineered immune cells: Solid tumors defeat CAR-T by telling immune cells to stand down. These new cells in the trial presented were built to ignore that signal, and tumors shrank in 89% of patients with advanced liver cancer who'd failed four treatments.
The catch: unfortunately it lasted only about 4 months, which is not enough yet for a very expensive treatment. But the response rate is very impressive.
https://t.co/hPUU20JmeI
2) Way closer to the clinic is a trial in bile duct cancer: An antibody combined with chemo doing two jobs beat the current best treatment of chemo and immunotherapy on survival. First time that's ever happened. Though the trial ran entirely in China, so it needs confirming elsewhere.
https://t.co/nTcMDuo8oQ
The field is moving forward with new ideas stimulating the immune system to fight the cancer, in my opinion the most promising route for durable treatment success.
Incredible talk at #ESMO26 on reharnessing the historical success of interleukin therapy in RCC/melanoma through cytokine-armored T cell approaches.
🎯 Cytokine-armored CAR-T cells allow targeted delivery of cytokines and even T cell repurposing

SMALL CELL LUNG CANCER MAY HAVE JUST ENTERED A NEW ERA!
For decades extensive stage small cell lung cancer has challenged oncologists with rapid growth! Early dissemination! Initial chemotherapy sensitivity! And devastating relapse!
Today at ESMO 2026 we witnessed something remarkable!
The Phase 3 DeLLphi 305 trial enrolled 563 patients whose cancer had not progressed following platinum etoposide and durvalumab!
Investigators compared maintenance durvalumab alone against durvalumab combined with tarlatamab!
THE RESULTS DEMAND ATTENTION!
Median overall survival improved from 12.7 months to 21.1 months!
The hazard ratio for death was 0.42!
Median progression free survival increased from 1.9 months to 7.4 months!
At one year approximately 79% of patients receiving the combination remained alive compared with 53% receiving durvalumab alone!
These are not simply changes in tumor measurements!
These are meaningful survival gains in one of the most aggressive malignancies we treat!
BUT WHY DOES THIS MATTER BIOLOGICALLY?
Small cell lung cancer frequently expresses DLL3!
Tarlatamab is a bispecific T cell engager that binds DLL3 on malignant cells and CD3 on T lymphocytes!
It physically brings the immune system into contact with cancer!
Durvalumab blocks PD L1 mediated immune suppression!
Together these agents may help overcome complementary barriers to antitumor immunity!
This raises an extraordinary possibility!
Perhaps the future of small cell lung cancer is not simply stronger chemotherapy!
Perhaps it is earlier and more effective immune redirection!
BUT WE MUST ASK HARDER QUESTIONS!
Why do some patients achieve durable disease control while others progress?
Could circulating tumor DNA identify molecular relapse before radiographic progression?
Could single cell sequencing reveal exhausted T cell populations that predict resistance?
Could spatial transcriptomics identify tumors where T cells cannot effectively reach DLL3 expressing malignant cells?
Could serial tumor and blood sampling reveal whether DLL3 expression changes under treatment pressure?
And could adaptive trials use these biomarkers to identify who benefits from earlier treatment?
We must also confront toxicity!
Cytokine release syndrome occurred in approximately half of patients receiving the combination and was predominantly low grade!
Neurotoxicity and the need for specialized monitoring cannot be ignored!
Longer survival must be accompanied by preserved quality of life!
THE NEXT EXPERIMENT MATTERS!
I would propose a prospective translational study combining serial circulating tumor DNA! DLL3 expression! T cell receptor sequencing! And immune profiling before and during maintenance!
The goal would be to identify the biology of durable responders and develop rational combinations for patients who develop resistance!
As an oncologist caring for patients with advanced cancer I believe our responsibility extends beyond celebrating positive trials!
We must determine how to convert longer survival into durable remission!
And eventually cure!
Congratulations to Jacob Sands and the international DeLLphi 305 investigators!
The next chapter should be written through collaborative science!
Could DLL3 directed immune engagement combined with molecular monitoring become the foundation for preventing small cell lung cancer relapse?
