The oncology KOL conversation on X today is led by Lung Cancer, Breast Cancer, 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 positive topline results from the Phase III OptiTROP-Lung06 trial, where the Trop-2 ADC sacituzumab tirumotecan (sac-TMT) plus pembrolizumab demonstrated superior PFS with a positive trend in OS versus chemo-IO in first-line PD-L1 negative non-squamous NSCLC. Also trending is the Phase III ELEVATE trial, which showed adjuvant ensartinib improved disease-free survival in resected ALK-positive NSCLC. A new meta-analysis found chemoimmunotherapy superior to PD-(L)1 monotherapy in advanced NSCLC with PD-L1 ≥50%.

“A meta-analysis of 24 phase III trials (5,546 patients) found superior outcomes with chemoimmunotherapy over PD-(L)1 monotherapy in advanced NSCLC with PD-L1 ≥50%: • OS: HR 0.85 • PFS: HR 0.61”

“Phase III OptiTROP-Lung06 meets primary endpoint. First-line sacituzumab tirumotecan (sac-TMT, Trop2 ADC) + pembro vs chemo + pembro in PD-L1 negative non-squamous NSCLC. Sac-TMT + pembro had superior PFS with OS trend. Will ADCs push out chemo?”

“The phase III ELEVATE trial demonstrated that 2 years of adjuvant ensartinib after complete resection significantly improved disease-free survival in patients with ALK-positive NSCLC.”

“Key point: We should NOT use of afatinib outside of EGFRm NSCLC”

Key clinical questions include the choice between doublet vs. triplet regimens and sequencing considerations for patients with ESR1 mutations. Separately, physicians are weighing the sequential use of tucatinib and trastuzumab deruxtecan (TDXd) for HER2+ brain metastases.

“Gedatolisib now approved for PIK3CAwt ER+ MBC. Very active regimen, many open questions: - triplet vs doublet. I’d favor doublet to optimize the benefit/risk ratio - IV infusions clearly add burden, shared decision making is key - if ESR1 mutant, SERD combos may be prioritized”

“FDA approved gedatolisib ((RPI3K/AKT/mTOR-PAM inhibition) + fulvestrant ± palbociclib for PIK3CA-WT HR+/HER2- mBC post-CDK4/6i. First PAM inhibitor to land in the WT space.”

“Tucatinib and TDXd are the two most effective drugs for patients facing HER2+ breast cancer brain metastases. Adding them together led to a PFS of 20 months for BM patients. For now best to use these agents sequentially and not together.”

In prostate cancer, the Phase 3 PROTEUS trial of perioperative apalutamide plus ADT met its dual primary endpoints in patients with high-risk localized/locally advanced disease. In kidney cancer, key topics include the updated NICE 2026 guideline and a new adjuvant treatment algorithm. One physician noted that '87% of stage 1a RCC in the UK is diagnosed incidentally,' highlighting challenges in early detection.

“87% of stage 1a RCC in the UK is diagnosed incidentally. A reminder of how challenging early detection remains in everyday clinical practice.”

There is also a focus on the safety of advanced therapies, including real-world data on the risk of second primary malignancies with CAR T-cell therapy and the management of common toxicities. Ongoing debates center on the future of CAR-T and the development of fixed-duration therapeutic approaches.

“Retrospective study suggests high FCRL5 expression predicts poor treatment response & survival (median PFS 10.6 months vs. not reached, P = 0.002) and OS 13.2 months vs. not reached, P = 0.02)) in newly diagnosed myeloma:”

Other discussions include a newly identified mechanism of resistance to tagraxofusp in BPDCN, linked to decreased TXNRD1, and monitoring strategies for patients on menin inhibitors.
