Treatment of recurrent and metastatic adenocarcinoma of the endometrium with cisplatin, doxorubicin, cyclophosphamide, and medroxyprogesterone acetate.
We conducted a retrospective review of 44 patients with metastatic or recurrent endometrial carcinoma treated with cisplatin, doxorubicin, cyclophosphamide, and medroxyprogesterone acetate. Thirty-six women had metastatic disease; eight had recurrent disease. In the metastatic group, 12 women had positive peritoneal cytology as the only criterion for metastatic disease. Grade 1 tumors represented 25%, grade 2, 47.7%, and grade 3, 27.3%. The series was divided into four groups based on disease volume before chemotherapy: positive peritoneal cytology only (N = 12), microscopic (N = 11), macroscopic less than 2 cm (N = 6), and macroscopic greater than 2 cm (N = 15). Fifteen patients had measurable disease and eight (53%) had an objective response. The median survival was 31 months for the whole group. Median survivals were not reached for the positive peritoneal cytology only and the microscopic groups. Median survival for the macroscopic less than 2 cm and greater than 2 cm groups were 15 and 10 months, respectively (P less than .0001). The volume of disease was the most important factor in determining survival as well as the time to progression (P less than .0001). The distribution of grade was similar in all groups (P = .88), and grade did not predict survival (P = .80) or recurrence (P = .87). The significant number of low-grade lesions in our series as well as the importance of positive cytology as a predictor of survival underscore the need for surgical pathologic staging in an effort to identify those patients in need of adjuvant therapy.
