[Radiotherapy for brain metastasis of malignant trophoblastic tumor]

From 1982 to 1985, 26 patients with malignant trophoblastic tumor were treated. Of them, 8 patients developed brain metastasis. Seven out of these 8 patients were treated with 60Co whole brain radiotherapy. The total dose on the longitudinal mid-plane of brain was 3300 cGy/2-3 weeks. Four patients were cured, 3 of them have survived without recurrence or sequelae for 6.5, 6 and 4.5 years, respectively; the other one died of liver metastasis 1 year after radiotherapy. Radiotherapy is an effective method in the combined treatment for brain metastasis of malignant trophoblastic tumors.
