A series of uterine leiomyosarcomas was reviewed in an attempt to assign prognostic significance to clinical and pathologic features. Extension of the sarcoma at the time of initial diagnosis was associated with a dismal outcome; no patient with disease beyond the confines of the uterus survived. Histologic grade was a useful prognostic feature, although low-grade sarcoma can be associated with metastases. Mitotic count was also useful in prognosis, although it did not correlate as well with clinical outcome as did histologic grade. There was no number of mitoses below which the diagnosis of leiomyosarcoma was excluded.
