View post ↗Full ATOMIC trial coverage on KOL Pulse →Also approved: HER2CLIMB-05 tucatinib maintenance — KOL Pulse profile →A radiation oncologist's question about neoadjuvant chemo-immunotherapy in stage III NSCLC drew a thread on patient selection, MDT discord and whether surgery after chemo-immunotherapy is really superior to definitive chemoradiation plus immunotherapy, with PACIFIC as the anchor and InDuRanS as the trial that may answer it; Dr. Drew Moghanaki, Dr. Rohit Singh, Dr. Banu Atalar and Dr. Linda Martin weigh in below. In the same stage III setting, the LAURA post-progression analysis is now online in Clinical Cancer Research: osimertinib after definitive chemoradiation improved TFST (HR 0.13), PFS2 (HR 0.62) and TSST (HR 0.51), with a second interim OS of HR 0.67 (95% CI 0.40–1.14, 31% maturity) — Dr. Stephen V Liu and Dr. Masahiro Torasawa post the numbers. Separately, the Phase 3 FURVENT trial of first-line firmonertinib in EGFR exon 20 insertion NSCLC did not meet its primary PFS endpoint.

“Very well stated. Unfortunately, I'm continuing to meet thoracic oncologists who have become blinded by their enthusiasm for nCIO and are not actually thinking about the consequences of poor patient selection. And when radiation oncologists question recommendations for a surgical management plan, they are cast as biased. It is my opinion that the discord among specialists taking care of stage III NSCLC has reached unprecedented levels in the history of lung cancer care. This is simply not acceptable, and our patients expect more of us while we keep touting that we provide "MDT care". We need more people to speak up and ask the difficult questions needed to optimize patient selection and match the best treatment for each and every patient with stage III NSCLC. We also need more adults in the room to make it clear that it's okay to question our recommendations. ”

“It seems more pronounced among med oncs who were previously biased to over-recommend PACIFIC, and not necessarily thinking about the local therapy type. I’ve discussed this with several influential medoncs who hesitated to agree, but eventually saw the light. Curious of your perspective.”

“The distinction I think gets lost is between proving that perioperative IO improves a surgical strategy and proving that the surgical strategy is superior to definitive CRT + IO. We have excellent evidence for the former, but not the latter. INT0139/ESPATUE never demonstrated an OS advantage for surgery, while modern perioperative trials have dramatically improved surgical outcomes. Conversely, PACIFIC cannot establish superiority of CRT in operable disease. That is genuine equipoise, particularly in N2 disease, and exactly why trials such as InDuRanS are important. Until then, careful MDT selection; not “resectable = surgery” or “stage III = CRT”; seems the most evidence-based approach.”

Trial PI Dr. Erika Hamilton welcomed a maintenance option for HR-negative patients; the discussion then turned to where the regimen fits against T-DXd, DESTINY-Breast09 and PATINA. The same week Dr. Paolo Tarantino published "Right-sizing treatment for HER2-positive breast cancer: evolving algorithms across the disease continuum" in Nature Reviews Clinical Oncology with Valenza, Segui, Lin, Prat, Curigliano, Waks and Tolaney — his thread below walks through how T-DXd and the other antibody-drug conjugates are reshaping the curative and metastatic algorithms. Dr. Neil Vasan, Dr. Yakup Ergün and Dr. Mali Barbi lay out their sequencing.

“2/ In the curative setting, therapy can be finally tailored to the tumor biology and patient features. Many patients can get away with abbreviated THPx12. Adding T-DXd can boost pCR rates (DB11) or rescue resistant tumors (DB05). AC is mostly gone, TCHP rapidly losing ground.”

“Although the FDA approval of tucatinib based on HER2CLIMB-05 expands maintenance options after first-line therapy, when considered alongside the DB-09 and PATINA data, it is unlikely to be my preferred option. If I were to use it, I would consider maintenance tucatinib + trastuzumab + pertuzumab particularly for patients with HER2 3+ disease, no visceral metastases, HR-negative disease (if used in HR-positive disease, please use it together with endocrine therapy), and PIK3CA wild-type tumors.”

“FDA approved #HER2CLIMB05. Metastatic HER2+ #breastcancer is now crowded, and there is no sequencing trial. Until there is one, here is how I think about it. Most of my patients will see T-DXd in the neoadjuvant or adjuvant setting. When they recur, HER2CLIMB-05 with tucatinib comes into play. If she is HR+, palbociclib per PATINA. If she has not seen T-DXd, I start with T-DXd. Brain metastases are the hard part. If I use T-DXd up front and she develops brain metastases, tucatinib is what I have left. So do I hold T-DXd for the brain, or use it first and keep tucatinib for the brain? I use it first as soon as I can and hope to better sequencing trials or new agents for subsequent lines”
— @DrBarbiOnc · Sequencing T-DXd, tucatinib and brain metastases · View post ↗On October 8 the FDA approved atezolizumab with a fluoropyrimidine and oxaliplatin as adjuvant treatment for patients 2 years and older with stage III dMMR colon cancer, based on ATOMIC (investigator-assessed DFS HR 0.50, 95% CI 0.35–0.73; median DFS not reached; OS immature; no companion diagnostic, per the FDA notice). Dr. Ilyas Sahin summarizes the NEJM data (3-year DFS 86.3% vs 76.2%) and the side-effect trade-off; the ASCO 2025 plenary cited 86.4% vs 76.6%. The day-one debate is adjuvant vs neoadjuvant: today's top story asks how much the chemotherapy backbone adds, and Dr. Yakup Ergün argues for NICHE-2-style neoadjuvant immunotherapy with reflex MMR testing.

“The FDA has approved atezolizumab + chemotherapy after surgery for stage III colon cancer with mismatch repair deficiency (dMMR: 10-15% of all Stage III colon cancer cases). A subcutaneous formulation (Tecentriq Hybreza) was also approved. In the phase III ATOMIC trial (712 patients, NEJM): - 3-year disease-free survival: 86.3% vs 76.2% - 50% reduction in the risk of recurrence or death (HR 0.50) In the trial, treatment was 6 months of FOLFOX + atezolizumab, followed by 6 months of atezolizumab alone. An important advance for patients with this type of colon cancer, although increased side effects remain a consideration.”

“The scientific evidence is clear, and I have nothing to argue with there. However, with the NICHE-2 data available, I still find it difficult to accept this adjuvant approach. I think MMR status should be routinely assessed by reflex IHC testing on endoscopic biopsy specimens in all patients with colon cancer, and neoadjuvant immunotherapy should be seriously considered in eligible patients with dMMR tumors🕵♂️”

A Phase 2 randomized trial of PSMA-PET-guided radiotherapy intensification in prostate cancer did not meet its primary endpoint of 5-year failure-free survival (66% vs 62%, p=0.14), though it did improve the secondary endpoint of biochemical failure-free survival (72% vs 65%, p=0.048). Discussion is also focusing on NECTIN4 as a predictive biomarker for enfortumab vedotin, with emphasis on the need to prospectively validate standardized scoring of membranous expression before clinical use.
