Ten years' experience with trophoblastic tumors in Portugal.

Between 1971 and 1980, 220 patients were observed and treated. The patients were classified according to various parameters: age, previous pregnancies, pathology reports of specimens obtained from the uterus, and site of metastasis. The study stressed the possibility of 100% cure in patients with hydatidiform mole, while in choriocarcinoma, late diagnosis was responsible for the failure in effective treatment.
