[Treatment of Ewing's tumor (author's transl)]

Eight cases of Ewing's tumor are reported. Four cases (50%) were localized forms at diagnosis and the remaining presented metastasis. The localized forms were treated with a combination of irradiation at dose of 4,500-5,000 rads and chemotherapy with vincristine and cyclophosphamide during two years. Three of these patients (75%) are alive and free of disease for more than two years. In the metastatic forms the treatment used was radiotherapy and diverse chemotherapy combinations with palliative intention. Bibliography related with this subject is reviewed and new chemotherapeutic combinations are discussed, the superiority of any treatment being not yet established.
