Popis: INTRODUCTION Ovarian cancer is a rare cause of brain metastasis requiring neurosurgical intervention. Management strategies vary and prognostic factors are not well known. OBJECTIVE We aim to systematically review the literature on management and outcomes of ovarian cancer brain metastasis and compare it with our experience. METHODS Systematic review was performed using PRISMA guidelines. Databases were sourced from inception to April 2022. Study selection was based on predetermined inclusion/exclusion criteria. A simultaneous retrospective analysis was performed on patients from our institution who underwent evaluation and treatment for metastatic intracranial lesions of ovarian origin. RESULTS Literature search generated 214 articles. Twelve were ultimately selected, representing 428 brain metastasis (BM) patients from ovarian cancer. Patients age from 27-80 years. The interval from cancer diagnosis to BM ranged from 0 – 226.2 months. Surgical resection (SR), stereotactic radiosurgery (SRS), and whole-brain radiotherapy were the most frequently used treatment modalities. Individual patients’ overall survival following BM diagnosis ranged from 0 – 173 months. For our institutional analysis, 9 patients were included with median age of 56 years. Median interval from diagnosis to BM was 51 months. Four patients were treated with SR and adjuvant SRS. Two patients had SR and SRS with additional extraventricular drain placement. Two patients had SR only, and one received only SRS. Median radiation dose received was 20 Gy. For those who experienced progression, median progression-free survival was 14 months. One patient exhibited no progression at the time of analysis. Three patients were alive at the time of analysis with two others lost to follow-up. CONCLUSION brain metastases following ovarian cancer are a rare outcome carrying a poor prognosis. Multimodal therapies, specifically SR and SRS, correlate with increased survival. Further study is needed to better guide optimal management, with particular attention to the benefits of resection with targeted adjuvant radiation.
