Adjuvant chemotherapy with cisplatin, ifosfamide, and doxorubicin followed by radiotherapy in localized uterine sarcomas: results of a case-control study with radiotherapy alone

Uterine sarcoma is a poor prognosis disease, with a high risk of metastatic relapse. We conducted a study of adjuvant chemotherapy with cisplatin, ifosfamide, and doxorubicin followed by radiotherapy (n=18). The results were then compared in a matched case-controlled study to radiotherapy alone (n=16) or no therapy at all (n=2). Chemotherapy consisted in three cycles of adriamyein-platinum-ifosfamide (API) (doxorubicin 60 mg /m2 on day 1; cisplatin 100 mg /m2 on day 2; ifosfamide 5 g /m2 on day 1+mesna 5 g /m2 on day 1+granulocyte colony-stimulating factor; q 3 weeks). Drug doses were reduced (20% for ifosfamide and cisplatin) four times (four patients) due to hematologic toxicity. Compared to a case-control study of adjuvant radiotherapy alone, results were not decreased by the addition of a toxic chemotherapy. CONCLUSION: Adjuvant API chemotherapy followed by radiotherapy is a feasible protocol; a multicenter phase III study comparing radiotherapy alone versus API chemotherapy followed by radiotherapy just began in France.
