The GPO Cooperative Ewing's Sarcoma Study (CESS) 81 with 10 months four-drug combination chemotherapy (vincristine, actinomycin D, cyclophosphamide, and adriamycin = VACA) and local control with surgery and/or radiation, following week 18, resulted in a Kaplan-Meier estimated disease-free survival of 51% after 6 1/2 years (51/93 patients disease-free). Tumor volume and histological response to primary chemotherapy were identified as most significant prognostic factors. As a consequence, the CESS 86 regimen was stratified according to risk of relapse. Standard risk patients (extremity tumors < 100 ml tumor volume) were continued on VACA chemotherapy. In high risk patients (extremity tumors > 100 ml tumor volume, central tumors), cyclophosphamide in conventional dose (1200 mg/m2/course) was replaced by high doses of ifosfamide (6 g/m2/course) with mesna uroprotection (VAIA). Local control was obtained following week 9. Patients with radiation were randomised for conventional fractionation or accelerated split-course hyperfractionation. The study was piloted from February to December 1985. 27/37 patients were disease-free on October 1, 1987. The ongoing trial was started on January 1, 1986. On October 1, 1987, 63/66 patients were disease-free. In patients with large primaries, according to Kaplan-Meier life-table analysis, the disease-free survival was significantly better in patients receiving VAIA chemotherapy, compared to the previous VACA regimen. The toxicity of both combination chemotherapy regimens was comparable.
