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 Phase 3 SAFFRON trial met its primary endpoints, showing that investigational savolitinib plus osimertinib significantly improved both PFS and OS versus platinum-based chemotherapy for patients with EGFR-mutated NSCLC with MET overexpression/amplification after progression on osimertinib. Additionally, the Phase 3 DESTINY-Lung04 trial demonstrated that investigational trastuzumab deruxtecan (T-DXd) improved PFS compared to pembrolizumab plus platinum-based chemotherapy in the first-line setting for metastatic HER2-mutant NSCLC. Discussion is also noting a JTO update on harmful outcomes of neoadjuvant chemoimmunotherapy in poorly selected patients with stage III NSCLC.

Separately, real-world data on metastatic breast cancer post-T-DXd suggests switching the chemotherapy's mechanism of action is the most effective strategy, while the benefit of early ctDNA-guided intervention in triple-negative breast cancer remains uncertain.

Separately, an upcoming symposium will focus on young adult cancers, including colorectal and genitourinary malignancies, and supportive care.

In favorable intermediate-risk prostate cancer, stereotactic body radiation therapy (SBRT) with 5 fractions was not superior to 20–28 fractions for 3-year disease control, though it offers greater convenience. For urothelial cancer, high blood levels of IL-6/CRP are associated with an immunosuppressive tumor microenvironment, suggesting a potentially targetable axis of resistance to immunotherapy.

Separately, discussion from the #SeattleCT26 summit on choosing between cilta-cel and teclistamab-daratumumab at first relapse concluded there is no single right answer, but recommended early involvement of a CAR-T center to preserve future options.
