    Added text to state that the duration of primary chemotherapy ranges from 6 months to approximately 1 year. Also added text to state that a randomized clinical trial from the Children's Oncology Group showed that for patients presenting without metastases, the administration of cycles of cyclophosphamide, doxorubicin, and vincristine alternating with cycles of ifosfamide and etoposide at 2-week intervals achieved superior event-free survival (EFS) than alternating cycles at 3-week intervals (cited Womer et al. as reference 20).

    Added text to state that the cumulative incidence of subsequent neoplasms in children treated for Ewing sarcoma between 1970 and 1986 at 25 years after diagnosis was 9.0%. Most of these patients received radiation therapy; comparable long-term data do not yet exist for significant numbers of patients who did not receive radiation therapy (cited Ginsberg et al. as reference 65).

    Ewing Sarcoma: Localized Tumors

    Revised text to state that patients randomly assigned to the every 2-week interval of treatment had an improved 5-year EFS (73% vs. 65%, P = .048) (cited Womer et al. as reference 14).

    Ewing Sarcoma: Recurrent Tumors

    Added Malempati et al. as reference 18.
