Aims and Objectives: To review a series of patients with brain metastases from ovarian cancer at a single institution. To describe treatment modalities, their outcomes and to determine prognostic factors. Patients and Methods: Between January 1995 and December 2014, 25 patients with ovarian cancer brain metastases were treated at The Sheba Medical Center. The medical records were retrospectively reviewed to collect demographic, clinical, and imaging data as well as the information on the treatment modalities used and their outcomes. Results: Mean patient age at the time of brain metastasis diagnosis was 62.7 years. The median interval between the diagnosis of primary cancer and brain metastasis was 42.3 months. Neurologic deficits, headache, and seizure were the most common symptoms. The brain was the only site of metastasis in 20% of the patients. Active ovarian cancer at the time of diagnosis of brain metastasis was observed in half of the patients with systemic disease. Multiple brain metastases were observed in 25% of the patients. We treated 11 patients with surgery plus radiation therapy protocols in various orders: surgery followed by complementary whole-brain radiation therapy (WBRT), surgery followed by stereotactic radiosurgery (SRS), and surgery followed by WBRT and then by adjuvant SRS. Five patients underwent surgery alone and nine patients were treated with radiation alone (WBRT, SRS, or both). Univariate analysis for predictors of survival demonstrated that age above 62.7 years at the time of central nervous system involvement was a significant risk factor and leptomeningeal disease was a poor prognostic factor in reference to supra-tentorial lesions. Multivariate analysis for predictors of survival, however, showed that multiple brain lesions (>4) were a poor prognostic factor, and multivariate analysis of the time to progression revealed that combined treatments of surgery and radiation resulted in longer median periods of progression-free survival than each modality alone. Conclusion: We conclude that the only significant predictors of survival or progression-free survival in our cohort were the number of brain metastases and the treatment modality.
