ENDOMETRIOID CARCINOMA OF THE OVARY - RETROSPECTIVE REVIEW OF 145 CASES

From 1967 through December 1987, 145 patients with endometrioid carcinoma of the ovary were treated at the University of Texas M. D. Anderson Cancer Center. Thirty-eight patients (26.2%) had stage I disease, 28 (19.3%) stage II, 60 (41.4%) stage III, and 11 (7.6%) stage IV; 8 patients (5.5%) were unstaged. Grade 2 or 3 histology was seen in 119 patients (82.1%). In addition to surgical therapy, 128 patients underwent chemotherapy, including single-agent therapy, noncisplatin combination therapy, and cisplatin-based therapy. No statistically significant improvement in median survival was noted among these three chemotherapy groups for stages II, III, and IV (P = 0.22). A significant improvement in median survival was noted for those patients who achieved a complete clinical response, regardless of type of chemotherapy (96 or more months for single-agent therapy, P = 0.001; 31.5 months for noncisplatin combination therapy, P = 0.016; and 85 months for cisplatin-based therapy, P = 0.0001). Synchronous ovarian and uterine malignancies were seen in 18 patients (12.4%). No difference in survival was seen for patients with endometriosis (P = 0.13) or endometrial cancer (P = 0.09) when compared with those who did not have these histologic findings. © 1990.
