Mixed müllerian tumors of the uterus: a clinicopathologic study

Abstract

Forty-seven cases of mixed müllerian tumors of the uterus were analyzed clinically and pathologically. All patients but one were postmenopausal. Vaginal bleeding was the most frequent presenting symptom, followed by abdominal mass and pelvic pain. Long-term survival was found only in those cases in which the tumor was localized to the uterus (surgical stage I), particularly if it arose from a benign endometrial polyp. No correlation could be established between survival and tumor size, depth of myometrial invasion, or histologic type of sarcoma. Tumors arising after previous irradiation had a poor prognosis. Treatment included surgery, radiation, and chemotherapy. The cumulative probability of 5-year survival was 35%.
