Uterine sarcoma in the south of Israel: study of 36 cases.

BACKGROUND

Uterine sarcomas are rare, charaterized by rapid clinical progression and poor prognosis, and their management has been a challenge. The purpose of this study was to investigate the clinical and histologic findings, treatment, and outcome of patients with uterine sarcoma in the south of Israel.

METHODS

Data from the files of 36 patients with uterine sarcoma who were managed at the Soroka Medical Center between January 1961 and December 1994 were evaluated.

RESULTS

The 5-year survival rate was 32% overall; 63% for 9 patients with endometrial stromal sarcoma (ESS). 30% for 14 patients with mixed mesodermal sarcoma (MMS) and 18% for 13 patients with leiomyosarcoma (LMS): 41% for 22 patients with Stage I and 19% for 14 patients with Stages II, III, and IV. Only the difference in the 5-year survival rate between ESS and LMS was statistically significant (P < 0.05). Eleven patients (30.6%) were treated with surgery alone, 4 (11.1%) with surgery followed by pelvic radiotherapy, 11 (30.6%) with surgery followed by chemotherapy, 8 (22.2%) with surgery followed by pelvic radiotherapy and chemotherapy, one (2.8%) with chemotherapy alone, and one (2.8%) had no treatment.

CONCLUSIONS

Uterine sarcomas are aggressive tumors with a poor prognosis. The treatment is surgery generally followed by adjuvant pelvic radiotherapy and/or systemic chemotherapy.
