Abstract
Between 1977 and 1981 21 patients with metastatic ovarian germ cell tumours received sequential combination chemotherapy; 18 had malignant teratomas and three dysgerminomas. Thirteen patients with malignant teratoma have had no treatment for up to 45 months (mean 27.5 months) and one patient is still having treatment. Life table estimate of survival on 1 July 1981 projects a survival of 71% in those with malignant ovarian teratomas. Four patients with malignant teratoma have died. Two of these had received extensive treatment before referral and a third achieved complete remission but relapsed and did not subsequently respond fully to further treatment. A fourth patient had an undifferentiated tumour compatible with an embryonal carcinoma which proved refractory to all treatment. The three patients with advanced dysgerminomas are all in remission and have had no treatment for 5, 14 and 33 months respectively. The majority of metastatic germ cell tumours of the ovary now appear to be curable provided that effective treatment is begun early.
