A retrospective study on combination therapy with ifosfamide, adriamycin and cisplatin for progressive or recurrent uterine sarcoma

There is currently insufficient evidence to recommend a specific chemotherapeutic regimen as standard treatment for uterine sarcomas. In this study, we investigated the toxicity and effectiveness of ifosfamide, adriamycin and cisplatin (IAP therapy) in patients with progressive and recurrent uterine sarcoma. A total of 11 patients with progressive or recurrent uterine sarcoma containing leiomyosarcoma (LMS), undifferentiated endometrial sarcoma (UES) or adenosarcoma, who were diagnosed at our institution, were retrospectively investigated. We recorded the adverse events, response rate and progression-free survival in these cases. The histological types included LMS (54.5%), adenosarcoma (27.3%) and UES (18.2%). Grade ≥3 leukopenia or neutropenia were observed in all the cases, febrile neutropenia developed in 45.5% of the patients and grade 4 thrombocytopenia developed in 3 cases (27.3%). With IAP therapy, the response rate was 36.4% and the disease control rate was 90.9%. Therefore, IAP therapy may be a viable option as chemotherapy for uterine sarcoma.
