Treatment of uterine leiomyosarcoma.

We reviewed 46 cases treated at the Gynecology Service of Memorial Sloan-Kettering Cancer Center from 1970-1984 to evaluate the impact of modern multimodal therapy on survival of patients with uterine leiomyosarcoma. Eighteen patients had their primary treatment at Memorial Hospital, whereas the remaining 28 patients were referred either after primary surgery (ten) or after the development of recurrent disease (18). Thirty-four patients initially had disease confined to the uterus. Twelve of these patients received various adjuvant treatment regimens after hysterectomy, and 83.3% developed recurrent disease; 68.2% of 22 patients who received no adjuvant therapy developed recurrent disease. Twelve patients who presented with extrauterine disease all died within two years of initial treatment. Thirty-seven patients were treated for persistent or recurrent disease after primary treatment. No objective responses to radiation therapy were seen in these patients. Doxorubicin used alone or in combination produced a 16.7% response rate (average duration four months), whereas there were no responses to chemotherapeutic regimens not containing doxorubicin. The disease-free survival rate for all patients in this study was 22%; those patients who presented with stage I and II disease had a 29% survival rate.
