title: [Ewing's sarcoma. Results of treatment in 16 consecutive cases].
abstract: In the period January 1974-August 1981, 16 previously untreated cases of Ewing's Sarcoma have been diagnosed at the Giannina Gaslini Children's Hospital Genova. Eight were male, eight female. Median age at diagnosis was 11 years. Two patients presented with a unique metastatic lesion, in the right lung and in an illiac lymph node, respectively. Fourteen patients have been initially treated with local radiotherapy (dosages ranging form 4,800 to 6,600 rads) in association with antiblastic polichemotherapy utilizing 4 drugs (Adriamycin, Actinomycin D, Vincristine, Cyclophosphamide). The Rosen et al.'s T-2 protocol was adopted, modifying the initial phase in order to give more weight to Adriamycin and reduce the toxic effects related to radio-chemotherapy combination. Two patients bearing a costal primary were immediately treated with a more complex and aggressive chemotherapy (T-6 Protocol), followed by local irradiation (in one case preceded by surgical ablation) and then chemotherapy again (T-2 protocol, second phase) for 10 months. Treatment determined a fast subjective relief in the 13 symptomatic patients. All 16 cases achieved a status of complete remission. Four of them subsequently relapsed: locally in two, in distant sites in the remaining 2. All 4 died 12-27 months form diagnosis. Twelve patients are presently alive without evidence of disease at 3-92 months (median 37 months) following diagnosis. Treatment has caused early and delayed toxicity in all cases. However, the entity of these complications varied considerably from one patient to an other. Age at diagnosis and site of primary tumor were the factors most relevant in this respect.
