Abstract
Between 1977 and November 1979 we have treated 53 patients with malignant teratomas (43 males, 10 females). Thirty (70%) out of the 43 male patients had advanced and bulky disease at the time of presentation. Using different drug combinations in a sequential manner as described below, results are as follows: of the initial 33 male patients, 22 (67%) have discontinued treatment (mean 9.5 months). Nineteen have responded completely and 3 have static computed tomography (CT) nodules. Life-table analysis projects a survival of 66% (analysis at 1 December 1979). Nine out of 10 ovarian teratoma patients are alive. Adverse prognostic factors at the start of treatment were recognized in 9/10 male patients and the 1 female patient who have died. Although the survival of patients with malignant teratomas has improved dramatically, there are still problems with drug resistance in patients with very advanced disease. Patients with these tumours should continue to be treated in centres specializing in managing what has now become a potentially curable disease in most cases.
