[A clinical study of the continuous intra-arterial infusion chemotherapy of Ewing's sarcoma]

Eight cases of Ewing's sarcoma were treated by continuous intra-arterial infusion chemotherapy (i.a. infusion). Five cases gave no evidence of disease (mean 4 yr. 7 mos.), and 3 cases died (3 mos, 1 yr. 11 mo, 2 yrs. 5 mos.). The term of i.a. infusion was 3 mos. to 2 yrs. 3 mos. (mean 12 mos). Except in 2 cases, the primary tumors were suppressed by i.a. infusion, so these cases were not operated and no relapse resulted. The cumulative survival rate by Kaplan-Meier's method was 56.3%. The i.a. infusion for Ewing's sarcomas implies the possibility of limb-saving treatment with no operation.
