🚨Rare cancers account for 25% of all cases, yet face trial designs built for the common. Limited accrual, scarce funding, rigid endpoints—these barriers persist. But hope lies in: 🔹 Basket & adaptive designs 🔹 Tumor-agnostic therapies 🔹 N-of-1 & AI-driven trial matching 🔹

Navigational bronchoscopy as the new standard for biopsy of lung nodules? Non-inferiority trial NEJM compared robotic bronch to transthoracic needle biopsy with similar accuracy (79% vs 74%) but bronch with lower risk of pneumothorax (3.3% vs 28.3%). nejm.org/doi/full/10.10…

Dr. Herbert Loong, MBBS, FASCO at #ASCO25 with update on SOHO-01 with sevanertinib (BAY 2927088) in #HER2 NSCLC. RR 60.5% in pts with prior treatment (no HER2 therapy), DOR 9.2m. In 1L setting, RR 59% and most ongoing. Safety notable for >80% of pts with diarrhea though.

Real world outcomes in #BRAF NSCLC reported Clinical Lung Cancer. 1L dabrafenib + trametinib RR 67%, PFS 13.1m compared to chemotherapy RR 39%, PFS 6.1m. D+T performed similarly across lines. Question remains: targeted vs immunotherapy first? I prefer targeted. clinical-lung-cancer.com/article/S1525-…

Comparison of EGFR NSCLC transformed to #SCLC vs de novo SCLC Lung Cancer Journal. OS shorter with transformed SCLC esp with high neuroendocrine marker expression. In transformed SCLC, OS with chemo-immunotherapy superior to chemo +/- TKI (15.4m vs 8.5m). lungcancerjournal.info/article/S0169-…
