Treatment, results and prognostic factors in stage I and II sarcomas of the corpus uteri

Abstract

One-hundred and four cases of Stage I and II uterine sarcomas treated at Rosewell Park Memorial Institute over a 27 year period are reviewed. Included are 30 cases of mixed mesodermal tumor, 27 cases of carcinosarcoma, 25 cases of endometrial stromal sarcoma, and 22 cases of leiomyosarcoma. Prognostic factors were found to include histologic classification, stage, uterine size, depth of myometrial invasion, and type of treatment. Endometrial stromal sarcomas had the best over-all prognosis. Radiation therapy alone was inadequate treatment, but was of adjunctive value to surgery in terms of increasing survival and decreasing pelvic recurrences in patients with endometrial stromal sarcoma, mixed mesodermal tumor, and carcinosarcoma. Patients with leiomyosarcoma did not benefit from adjunctive radiation therapy.
