Objective: To study the results of combination chemotherapy of uterine sarcoma after operation and recurrent tumor.
Methods: One hundred seventy-four cases of three major pathological subtypes of uterine sarcomas were treated in the Cancer Hospital from 1960 to 1996. Clinical data were analyzed of 51 cases of uterine sarcomas treated with postoperative adjuvant chemotherapy and 38 cases with recurrent tumors received 98 courses of chemotherapy. They were divided into 4 groups according to the adjuvant chemotherapy regimen: single drug, VAC, VAD, and other regimens. Chemotherapy regimens for recurrent tumors were VAD, PA/PAC, and other combination regimens including etoposide, ifosfamide, cisplatin, adriamycin.
Results: The 5-year survival rate of stage I-II uterine sarcoma patients was 54.9% receiving adjuvant chemotherapy. It was 72.7% in VAD group which was significantly higher than that in other regimen groups. The survival rate was related to the number of chemotherapy course. The chemo-sensitivity of various pathological types of recurrent uterine sarcomas was not different.
Conclusion: The 5-year survival rate does not improve in patients with stage I-II uterine sarcomas given postoperative chemotherapy. VAD is among the best regimens and at least 3 courses should be performed. The results of new treatment regimens such as EPA, IA, etc., must await further clinical observation.
