[Studies of solid ovarian tumors in Tokai District (author's transl)]

The prognosis of patients with ovarian carcinoma is believed as worst among malignant diseases in the field of gynecology. Multiple factors including clinical stage, histologic type and grade may play an important role in the prognosis of patients. Because of these factors and the few cases of ovarian carcinoma seen in any one center over a short period, the ability to make valid evaluation of these factors has been limited. We organized ovarian tumor studying group in Tokai district with eleven member hospital and analyzed 453 cases of solid ovarian tumor retrospectively. 1) Cumulative survival rate was calculated according to the clinical stages. Five year survival rate of stage 1 was about 80%, that of stage 2 was about 30% and that of stage 3 and stage 4 were around 10% respectively. 2) Cumulative survival rate was calculated according to histologic types. There was minor variation of survival by histologic types. When we compared with different histologic types by same clinical stages such as stage 1 and stage 3 there was no definite differences of survival rate except slightly poor prognosis in case of mucinous cystadnocarcinoma. 3) Cumulative survival rate was calculated according to histologic grading. Histologic grade affects the prognosis of patients with ovarian carcinoma.
