Why is this study being done?

OBJECTIVES: Primary - Compare the early response rates in patients with intermediate-risk rhabdomyosarcoma (RMS) treated with vincristine, dactinomycin, and cyclophosphamide (VAC) vs VAC alternating with vincristine and irinotecan hydrochloride (VI) in combination with radiotherapy. - Compare failure-free survival (FFS) and overall survival of patients treated with these regimens. Secondary - Compare FFS, local control, and survival of patients with intermediate-risk RMS treated with VAC and early (week 4) radiotherapy vs delayed (week 10) radiotherapy, using data from IRS-IV for historic comparison. - Compare the acute and late effects of VAC vs VAC alternating with VI, including the toxicity associated with concurrent VI and radiotherapy. - Compare the acute and late effects of VAC as delivered on this study to that administered on COG-D9803. - Correlate change in fludeoxyglucose F^18 positron emission tomography (FDG-PET) maximum standard uptake value from week 1 to week 4 and 15 with FFS. - Correlate UGT1A1 genotype with VI toxicity in patients receiving VAC alternating with VI. - Correlate CYP2B6, CYP2C9, and GSTA1 genotypes with VAC toxicity. - Prospectively evaluate and validate gene expression values with the intent to define the best diagnostic predictors and more powerful prognostic classifiers. OUTLINE: This is a prospective, historic control, randomized, multicenter study. Patients are stratified according to histology, disease stage, and clinical group (group III, stage 2 or 3 embryonal rhabdomyosarcoma [RMS] vs group I, stage 1 alveolar RMS vs group II or III, stage 2 or 3 alveolar RMS). Patients are randomized to 1 of 2 treatment arms. within 42 days of initial surgery or biopsy. - Arm I (VAC): Patients receive VAC chemotherapy comprising vincristine IV over 1 minute on day 1 of weeks 1-13, 16, 19-25, 28, 31-37, and 40; dactinomycin IV over 1-5 minutes on day 1 of weeks 1, 4, 13, 16, 19, 22, 25, 28, 31, 34, 37,and 40; and cyclophosphamide IV over 1 hour on day 1 of weeks 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, and 40. - Arm II (VAC/VI): Patients receive VAC chemotherapy alternating with VI chemotherapy comprising vincristine IV over 1 minute on day 1 of weeks 1-13, 16, 17, 19, 20, 22-26, 28, 31-34, 37, 38, and 40; dactinomycin IV over 1-5 minutes on day 1 of weeks 1, 13, 22, 28, 34, and 40; cyclophosphamide IV over 1 hour on day 1 of weeks 1,10, 13, 22, 28, 34, and 40; and irinotecan hydrochloride IV over 90 minutes on days 1-5 of weeks 4, 7, 16, 19, 25, 31, and 37. In both arms, treatment continues in the absence of disease progression or unacceptable toxicity. Patients* in both arms also undergo radiotherapy 5 days a week for 4-6 weeks beginning in week 4 (except patients with alveolar RMS rendered group I by amputation OR patients needing week 1 emergency radiotherapy for symptomatic spinal cord compression). NOTE: *Individualized local control plan that deviates from protocol-mandated radiotherapy allowed for patients ≤ 24 months of age After completion of study treatment, patients are followed periodically for ≥ 10 years. PROJECTED ACCRUAL: A total of 486 patients will be accrued for this study.
