| Abstract: | A clinicopathologic evaluation of 60 patients (median age, 66 years) presenting for primary treatment of uterine malignant mixed müllerian tumors between 1959 and 1982 was conducted. Surgical stage was utilized for assessment of survival by stage. With a minimum follow-up of 5 years, overall 2- and 5-year Kaplan-Meier survival estimates were 53 and 39%, respectively; they were 75 and 58% when disease was confined to the uterus and 27 and 15% when disease extended beyond the uterus. By log-rank and logit-rank analysis, surgical stage and depth of invasion stratified by stage were significant prognostic determinants; no significant association was found with carcinoma grade, sarcoma mitotic figure count, sarcoma histologic subtype, sarcoma necrosis, or capillary-like space involvement. No significant survival advantage was found for surgery plus irradiation or surgery plus chemotherapy compared with surgery alone after stratification according to stage. Progression-free survival after complete extirpation of macroscopic disease was not significantly different, stage for stage, between surgery alone and surgery plus radiotherapy. |
