SURGICAL STAGE-IV ENDOMETRIAL CARCINOMA - A STUDY OF 47 CASES

Between 1976 and 1991, 47 patients with surgical Stage IV endometrial carcinoma were treated. Patients were identified from the tumor registry and charts were retrospectively reviewed. Survival curves using the Kaplan-Meier product-limit method and Cox regression analysis were used to identify independent prognostic factors. Overall, median survival was only 12 months. Using univariate analysis there was no statistically significant difference in survival between age (P = 0.41), histology (P = 0.54), grade (P = 0.91), disease site (P = 0.32), or clinical stage (P = 0.87). In patients whose disease was surgically cytoreduced, the median survival was 18 months compared to 8 months in those who did not undergo surgery (P = 0.0001). Evaluation of other treatment modalities by univariate analysis revealed improved survival in those patients who received cyclophosphamide, doxorubicin, and cisplatin (P = 0.0007), decreased survival in those who received radiation therapy compared to surgery (P = 0.023), and no statistically significant difference in survival with progestins. By multivariate analysis successful cytoreduction was the only statistically significant prognostic variable (P = 0.04). This 15-year retrospective review confirms that prognosis for women with Stage IV endometrial cancer is extremely poor. However, if hysterectomy with cytoreduction is feasible, surgery should be performed because survival may be improved. © 1994 Academic Press, Inc.
