AbstractGynecologic malignancies represent some of the commonest causes of cancer in the female population. Despite their overall high prevalence, gynecologic malignancies have seldom been reported to metastasize to the brain. The incidence of gynecologic cancers spreading to the brain has been rising, and the optimal management of these patients is not well defined. A retrospective analysis of patients treated over the past ten years with gamma knife radiosurgery (GKRS) for metastatic gynecologic cancer to the brain was performed. Radiographic treatment response, tumor control, metastatic disease progression and survival data were analyzed. Eight patients with ovarian cancer, six patients with endometrial cancer and two separates who carried a diagnosis of cervical cancer or leiomyosarcoma harbored metastatic disease to the brain that was treated with GKRS. The median dose to the tumor margin was 20 Gy (range 10-22 Gy), and the median maximum radiosurgical dose was 31 Gy (range 16-52.9 Gy). Tumor control was achieved in all patients who had follow up imaging studies. Patients with ovarian cancer had prolonged median survival following GKRS compared to patients with endometrial cancer (22.3 vs 8.3 months, p = 0.02). The patient with cervical cancer survived 8 months following her GKRS in the setting of metastatic brain tumor progression, whereas the patient with leiomyosarcoma passed away within several weeks of treatment secondary to disseminated extracranial primary disease. GKRS is a safe and effective means of achieving intracranial tumor control for patients with gynecologic cancer that has spread to the brain.
