A clinico-pathologic study of 20 consecutive patients with leiomyosarcoma of the uterus seen over a 12-year period has been evaluated. Tumor extent at the time of diagnosis seems to be the main prognostic factor: 62.5% of the patients in stage I are alive and well from 1 to 7 years after the diagnosis as compared to 0% of the patients in all the other stages. The age of the patients and the number of mitotic figures also appear to have some prognostic value.
