Radiotherapy for patients with brain metastases and leptomeningeal carcinomatosis: prognostic factors and clinical outcomes.

ABSTRACT: Brain metastases and leptomeningeal carcinomatosis (LC) are complications of advanced-stage malignancies, associated with a poor prognosis. This study aimed to evaluate the role of prognostic factors and radiotherapy (RT) treatment approaches while taking toxicity into account. We performed a retrospective study and compared clinical characteristics, prognostic factors, toxicities and outcomes in patients with (1) parenchymal brain metastases (PM) (n = 275) vs. LC (n = 35) and (2) in patients with whole brain radiotherapy (WBRT) (n = 52) vs. WBRT + boost (n = 201). We found poorer survival (OS) of the LC group compared to PM patients in univariable analysis (not in multivariable analysis). LC patients predominantly underwent WBRT only, received surgical resection before RT less frequently
