Endometrioid carcinoma of the ovary. A clinicopathologic study of 75 cases

Abstract

A clinicopathologic study of 75 endometrioid carcinomas of the ovary was carried out. Thirty‐six of the patients were in clinical Stages I and II and 39 in Stages III and IV. There were 49 histologically “pure” endometrioid carcinomas. the remaining 26 showed histologic admixtures of other neoplasms of Müllerian derivation. Thirty‐six of the 75 cases were adenoacanthomas. By histologic grading, 45 were classified as Grades 1 and 2, 30 as Grades 3 and 4. Thirteen of the ovaries with carcinoma also harbored endometriosis. in 11 patients, there was a concomitant endometrial carcinoma. the 5‐ and 10‐year survival figures for the entire series were 40.5% and 32.7%. Survival did not differ significantly between various subgroups or with different modalities of treatment and correlated best with clinical staging. Five‐year survival was 92.5% in Stage I and 27.8%, 3.7%, and 0% in Stages II, III, and IV. Copyright © 1970 American Cancer Society
