Adjuvant chemotherapy in Ewing's sarcoma patients

At the Istituto Nazionale Tumori of Milan 60 patients with clinically localized Ewing's sarcoma were treated during 1965-1978 according to three different protocols. From 1965-1971, 18 patients received almost exclusively local therapy and 17 of 18 (94%) relapsed in a median time of 6 months. From 1971-1978 adjuvant chemotherapy according to two different drug schedules was employed after radiotherapy. Twenty-five of 42 (59%) are surviving and relapse-free at this time (follow-up 20-101 months).
