    Abstract:
    Between 1957 and February 1981, 782 patients received cytotoxic chemotherapy for gestational trophoblastic tumors (GTT) in the Department of Medical Oncology, Charing Cross Hospital (London, England). Sixty-nine (8.8%) patients had central nervous system (CNS) metastases. Thirty-three of them (48%) presented with CNS disease prior to treatment (CNS presentation group), and 36 (52%) developed CNS disease while on treatment, or relapsed in the CNS after an initial complete or partial remission (late CNS group). Treatment included systemic and intrathecal chemotherapy, and, in several cases neurosurgery, whole brain irradiation, and immunotherapy. Life-table analysis projects an overall survival of 49% for the CNS presentation group and 6% for the late CNS group. Prognosis has improved with time; prior to 1974, 38% of the CNS presentation group and none of the late CNS group survived. After 1974 overall survival has been 80% in the CNS presentation group and 25% in the late CNS group. The principal elements in the successful management of such cases are: (1) CNS prophylaxis with intrathecal methotrexate for patients at risk of developing brain metastases; (2) early detection of CNS lesions by prompt recognition of their clinical features, measurement of the ratio of CSF to serum human chorionic gonadotropin concentration, and appropriate use of computerized tomography of the brain; and (3) a combination of systemic and intrathecal therapy for patients developing brain secondaries.
