Fig. 3From: Real-world analysis of different intracranial radiation therapies in non-small cell lung cancer patients with 1–4 brain metastasesComparison of cumulative incidence of OS, iPFS, DBF-FS for patients with neurological symptoms (a, b, c) and for asymptomatic patients (d, e, f) among LINAC-SRS, WBRT group and WBRT + RTB groups. Abbreviations: LINAC-SRS, stereotactic radiotherapy based on linear accelerators; OS, overall survival; iPFS, intracranial progression-free survival; DBF-FS, distant brain failure-free survival; m, months; RTB, radiotherapy boost; WBRT, whole-brain radiotherapyBack to article page
