The oncology KOL conversation on X today is led by Lung Cancer, Breast Cancer, GI Cancers, GU Cancers, Multiple Myeloma, Leukemia & Lymphoma. The KOL Pulse Daily Digest of what verified physician (KOL) voices are discussing on X across lung, breast, GI, GU, multiple myeloma, and leukemia & lymphoma, ranked by engagement over the last 48 hours.
The thoracic oncology community is discussing several trial results. In ES-SCLC, a study of consolidation thoracic radiotherapy showed no PFS or OS benefit and was stopped for toxicity. In NSCLC, the phase 3 ZEAL-1L trial of niraparib plus pembrolizumab maintenance was negative, and a secondary analysis of LIBRETTO-431 found no benefit from adding pembrolizumab to chemotherapy for RET fusion-positive patients. A business development is also noted: a deal to bring the EGFR exon 20 inhibitor sunvozertinib to the US.

“No benefit in PFS or OS with consolidation XRT vs atezo alone. Trial stopped early due to toxicity.”

“Negative results from phase 3 ZEAL-1L trial @JTOonline. Pts with NSCLC completed induction chemo-immunotherapy, randomized to pembro maintenance with PARP inhibitor niraparib or placebo.”

“FINALLY! AstraZeneca reaches deal with Dizal to bring sunvozertinib to the US! Approved for EGFR exon 20 NSCLC over a year ago but only available in China (and at a different dose).”

“A secondary analysis of LIBRETTO-431 found no significant differences in PFS or OS between chemoimmunotherapy (n=83) and chemotherapy alone (n=19).”

Other topics include a Phase I/II trial of 3-fraction accelerated partial breast irradiation (Tri-APBI) for early-stage disease and the long-term risk of distant recurrence in premenopausal patients.

“SERENA-6 Phase 3: Switching to camizestrant upon ctDNA-detected ESR1 mutation BEFORE progression (1L HR+/HER2- advanced BC) → Median PFS: 16.8 vs 9.2 months (HR 0.45) → Also significant PFS2 benefit”

“This is really important. Too many docs and patients underestimate the long term risk for distant recurrence in breast cancer. In premenopausal breast cancer these risk are VERY high.”

Other topics include translational research on how steatosis shapes liver metastasis heterogeneity in colorectal cancer, and a multicenter study suggesting staging laparoscopy may improve surgical outcomes for intrahepatic cholangiocarcinoma.

In renal cell carcinoma (RCC), topics include investigational approaches such as a CAIX-targeted imaging tracer for staging, the validation of KIM-1 as a biomarker, and adjuvant treatment decisions post-nephrectomy.

“An important approval for EV pembro for periop treatment of bladder cancer!”

“Staging kidney cancer with FDG PET has never really worked. A tracer aimed at CAIX, the antigen clear cell RCC almost always expresses, just showed why a target-specific approach fits the biology better.”

— @yao_zhu_sh · RCC biomarkers · View post ↗The myeloma/hematology community is discussing two new meta-analyses. One systematic review of 1,900 patients confirmed high activity for BCMA- and GPRC5D-directed bispecific antibodies in RRMM, with an overall response rate of 65.9% and median PFS of 8.8 months. A separate CAR-T analysis of over 7,600 patients found a non-relapse mortality rate of 6.8%, with the highest rate for ciltacel (15%). Also noted was the FDA's acceptance of the new drug application for mezigdomide based on SUCCESSOR-2 results.

“✅ ORR: 65.9% ✅ ≥VGPR: 51.0% ✅ ≥CR: 38.2% ✅ Median PFS: 8.8 months These results reinforce bispecific antibodies as an effective off-the-shelf immunotherapy option.”

“Future studies should focus on: ✅ Head-to-head comparisons ✅ Biomarker-driven patient selection ✅ Optimal sequencing after CAR-T or prior bispecific therapy ✅ Strategies to reduce infections and prolonged cytopenias.”

Also trending is the recent approval of imetelstat, a first-in-class telomerase inhibitor for transfusion-dependent anemia in MDS. Other topics include the integration of radiation with bispecific antibodies in B-cell lymphoma and a case report of a secondary T-cell lymphoma following bispecific CAR-T therapy.
