Real-world analysis of different intracranial radiation therapies in non-small cell lung cancer patients with 1–4 brain metastases

Stereotactic radiosurgery (SRS) has become a standard approach for the treatment of patients with few metastatic brain lesions. This study aimed to compare the survival outcomes and intracranial local control in NSCLC patients with 1–4 BMs who are treated with SRS using linear accelerators (LINAC-SRS), whole-brain radiotherapy (WBRT), or WBRT plus radiotherapy boost (WBRT+RTB).
