Brain metastases are the most common intracranial tumors. Overall, the only accepted prognostic factors are patient age and performance status. However, several other factors are considered before surgery. We performed a retrospective analysis of 309 patients who underwent surgical resection of newly diagnosed brain metastases between 1994 and 2004. Univariate survival analysis revealed age, performance status, extracranial metastases, complete resection, radiotherapy and re-craniotomy as prognostic indicators. Multivariate analysis determined that patient age, performance status, extracranial metastases, radiotherapy and re-craniotomy are independent factors of prolonged survival. We statistically estimated the age threshold separating patients with favorable outcomes from those with unfavorable prognoses. Using the Kaplan–Meier analysis this threshold can be set at 65 years. Multivariate analysis of patients >65 years revealed the presence of co-morbidities, the number of brain metastases, post-operative performance status and radiotherapy as independent prognostic factors.
