Highlights: Upfront LT delay intracranial progression, but do not prolong OS in oncogene-driven NSCLC. Use of stereotactic versus whole-brain radiotherapy and primary tumor TP53 status do not significantly affect brain control. Non-del19 EGFR mutations and ‘short’ EML4-ALK fusions are independent predictors of earlier intracranial failure. Results: Median overall survival (OS) was 49.1 months for ALK+ and 19.5 months for EGFR+ patients (P = 0.001), with similar median intracranial progression-free survival (icPFS) (15.7 versus 14.0 months, respectively; P = 0.80). Despite the larger and more symptomatic BM (P < 0.001) of patients undergoing early LT, these experienced longer icPFS [hazard ratio (HR) 0.52; P = 0.024], but not OS (HR 1.63; P = 0.12), regardless of the radiotherapy technique (SRT versus WBRT) and number of lesions. High-risk oncogene variants, i.e. non-del19 EGFR mutations and ‘short’ EML4-ALK fusions (mainly variant 3, E6:A20), were associated with earlier intracranial..... READ ARTICLE
