Clinical study on the treatment of malignant ovarian tumor--particularly the clinical management of dysgerminoma and common epithelial carcinoma.

In the department of Obstetrics and Gynecology of Kurume University, I, 355 cases of ovarian neoplasma were treated from 1960 to 1979, and of these cases 336 belonged to the semimalignant group and the most malignant group of the Japanese Ovarian Committee (J.O.C.). These groups are substantially grouped together into the category of malignant tumor by J.O.C., but their 5-year survival rates are considerably different, i.e., 67.6% for the semimalignant group and 30.8% for the most malignant group. Particularly, since tumors of the semimalignant group often occur in young women who must retain their generative functions, they must be treated differentially from the group of adenocarcinoma which appears frequently in rather aged patients. The present paper describes the clinical management of dysgerminoma, the incidence of which is high in the semimalignant group, and common epithelial carcinoma, the incidence of which is high in the most malignant group.
