Is stereotactic radiosurgery of brain metastases in patients with poor performance status worthwhile

192Background: Performance status is a consistent predictor of outcome in people with advanced disease. Variable prognosis has not led to the exclusion of patients with Karnofsky performance scores of < 70 from treatment of brain metastases (BRM) with stereotactic radiosurgery (SRS). The role of SRS for BRM in individuals with poor performance status (PPS) has not been elucidated to date. To better understand the prognostic utility of SRS in this particular patient cohort, we assessed the longevity periods of our treated PPS subjects with BRM. Methods: A retrospective review of patients with BRM treated by SRS during a 10-year period (2000-2009) identified 22 adult individuals with PPS; PPS was defined by the presence of severe hemiparesis or cerebellar ataxia. The primary endpoint of the analysis was survival because of some limitations in the obtained data. The mean follow-up was 26 months (range: < 1 to 144 months). Results: The mean age was 55.8 years, and the majority of the subjects were female. Mos...
