Abstract
Six patients with epithelial ovarian cancer had clinical diagnoses of central nervous system (CNS) metastases during a four-year period. A thorough review of the literature shows that involvement of the CNS by ovarian cancer is a rare phenomenon. Four of the six patients developed parenchymal brain metastases whereas carcinomatous meningitis was detected in the other two. These patients were younger and survived longer from initial diagnosis than the majority of women with ovarian cancer. Five of the six patients had previously received chemotherapy and had developed metastatic spread to extraperitoneal sites. Following extensive surgical resection, chemotherapy may provide intraperitoneal and systemic control, thereby extending survival and permitting occult CNS metastases to become apparent.
