Mixed Mullerian tumors of the uterus: clinical and pathologic correlations.

The 10-year experience at The Johns Hopkins Hospital with 61 cases of mixed Mullerian tumors were reviewed. The patients had a mean age of 63.7 years and the similar constitutional factors of diabetes mellitus, hypertension and nulliparity of endometrial adenocarcinoma. Only one patient had estrogen exposure. Eighteen percent had had prior exposure to pelvic radiation. The life table survival of the 61 patients was 41.1% at 5 years. The 2-year life table survival was 76% for disease confined to the uterus and 16.5% for extrauterine disease. There was no difference in survival between homologous and heterologous tumors. The surgical staging and the autopsies reviewed documented widely disseminated disease even when the tumor appeared to be confined to the uterus. It thus appears essential in order to improve survival these patients require aggressive staging and consideration of systemic adjuvant chemotherapy.
