A clinical and pathologic study of 34 sarcomas of the uterus.

The clinical and pathologic features of 34 uterine sarcomas were studied to determine the natural history of the disease. Sixteen patients had leiomyosarcoma, five mixed mesodermal sarcoma, ten endometrial stromal sarcoma, two carcinosarcoma and one endolymphatic stromal myosis. The patients were treated without an unique protocol. At 3 years the actuarial relapse-free survival was 53.6%: 68.4% in stage I-II patients and 22.2% in stage III-IV patients. As regards the histologic subtype mixed mesodermal sarcomas had the best prognosis; endometrial stromal sarcomas the worst. The necessity of a uniform clinical and histologic classification as well as the importance of controlled clinical trials are pointed out.
