[Therapy of non-metastatic Ewing's sarcoma (pelvis excluded). Results obtained in 48 cases combining local therapy (radiation and/or surgical) and adjuvant chemotherapy with vincristine, adriamycin, dactinomycin and cyclophosphamide]. / Terapia del sarcoma di Ewing non metastatico (pelvi esclusa). Risultati ottenuti in 48 casi associando alla terapia locale (radiante e/o chirurgica) una chemioterapia adiuvante con vincristina, adriamicina, dactinomicina e ciclofosfamide.

ABSTRACT

Combined therapy was used on a consecutive series of 48 patients with extrapelvic Ewing's sarcoma at the Rizzoli Orthopaedic Institute. The adjuvant chemotherapy protocol (VCR, ADM, D-ACT, EDX) was identical in all patients whereas local treatment consisted of amputation, resection and radiation treatment or radiation alone. At a mean follow-up of 58 months (39-78) 30 patients (60%) were free of the disease. This is a significantly higher percentage than that obtained in the same period with adjuvant chemotherapy using only 3 drugs (VCR, ADM, EDX). As far as the type of local treatment is concerned, the percentage of local recurrences and metastases was lower when the primary lesion was treated with surgery or surgery combined with radiotherapy, rather than radiation treatment alone. These suggest that if associated with radiation treatment and chemotherapy, surgery can play an important role that should be considered in the treatment of extrapelvic Ewing's sarcoma.
