Abstract
A retrospective analysis was performed of 20 patients with Ewing's sarcoma treated by combined modality therapy, consisting of surgery, radiotherapy, and chemotherapy. Fourteen patients (70%) achieved complete remission and 5 patients (25%) were in partial remission at the end of treatment. One patient (5%) failed to respond to combined modality therapy. The overall 5 year actuarial survival was 64% and the disease free survival, 55%. Persistent or recurrent disease occurred in 8 patients (40%); one of them was salvaged by surgery and chemotherapy. Site and extent of primary lesion were prognosticators of patients' outcome. One patient developed radiation‐related‐sequelae. The efficacy of aggressive management consisting of wide surgery, radiotherapy and intermittent high dose chemotherapy is discussed.
