Prognostic indicators of survival in advanced endometrial cancer.
Advanced endometrial cancer represents 14% of all stages but 54% of all deaths attributed to endometrial cancer. From 1973 to 1990, the charts of 137 patients with endometrial cancer (Stage III and IV) treated by the section of Gynecologic Oncology at Rush Medical College were retrospectively reviewed. The log rank method was used for univariate analysis and Cox proportional hazards regression was used for multivariate analysis. The patients were stratified as follows: Stage III, 92 (67.2%), Stage IV, 45 (32.8%); Grade 1, 15 (10.9%), Grade 2, 47 (34.3%), Grade 3, 67 (48.9%); adenocarcinoma, 93 (67.9%), adenosquamous, 18 (13.1%), adenoacanthoma, 2 (1.5%), clear cell, 1 (0.7%), papillary serous, 23 (16.8%). Using univariate analysis, median survival was 1.71 years for Stage III versus 0.68 years for Stage IV. Median survival based on treatment was as follows: radiotherapy (RT) only (n = 16), 0.89 years, surgery only (n = 36), 0.75 years, preoperative RT+surgery (n = 7), 2.5 years, surgery+postoperative RT (n = 56), 2.63 years, and other treatments (hormonal only n = 12, chemotherapy only n = 1, and no treatment n = 9), 0.6 years. Patients with vaginal extension survived a median of 0.82 years, versus 2.49 years without this factor (P = 0.002). Patients with clinically apparent parametrial involvement survived a median of 0.70 years versus 2.65 years without this factor (P = 0.0003). Multivariate analysis was possible via a surgical database (n = 99). Age > 60 (P = 0.01), parametrial involvement (P = 0.04), and abdominal metastases (P = 0.003) were significant prognostic indicators. Papillary or clear cell histology, advanced grade, and mode of treatment were not significant. Patients with abdominal metastases or parametrial extension of tumor have a significant decrease in mean survival.
