Fourty-six cases of trophoblastic tumor were experienced in our Clinic from 1951 to 1963. All cases were re-examined histologically and classified into chorioepithelioma, chorioadenoma destruens and undetermined group. 24 cases of chorioadenoma destruens were confirmed histologically and macroscopically by the presence of well preserved villi in the uterine muscle or parametrium. 13 cases of chorioepithelioma were diagnosed histologically. The remaining 9 cases could not be confirmed histologically, because the trophoblastic growth was not found in all removed specimens, or the amount of trophoblastic tissue was too scant to confirm the disease.
But all cases were diagnosed as trophoblastic tumor chorioepithelioma or chorioadenoma destruens by the presence of metastasis. The survivals over one year after surgery, whose pregnancy test continued negative, were 75% in chorioadenoma, 61.5% in chorioepithelioma and 66.7% in undetermined group. When 3 cases of undetermined, which were clinically supposed as chorioepithelioma, are added to chorioepithelioma group, its survival rate are reduced to 50%. 16 cases of 24 chorioadenoma, 7 cases of 13 chorioepithelioma and 5 cases of 7 undetermined group developed after hydatidiform mole.
