Adult Rhabdomyosarcoma Embryonal Childhood Rhabdomyosarcoma Embryonal-botryoid Childhood Rhabdomyosarcoma Previously Untreated Childhood Rhabdomyosarcoma | Procedure: conventional surgery Drug: dactinomycin Drug: cyclophosphamide Drug: vincristine sulfate Radiation: radiation therapy | Phase 3 |
PRIMARY OBJECTIVES:
I. Determine the failure-free survival of patients with newly diagnosed low-risk rhabdomyosarcoma treated with vincristine (V), dactinomycin (A), cyclophosphamide (C), and radiotherapy.
SECONDARY OBJECTIVES:
I. Determine local control rates in patients treated with this regimen. II. Determine the rate of second-look surgery in patients with bulk residual tumor at diagnosis (clinical group III) and the proportion of second-look surgeries that render patients treated with this regimen tumor-free or with microscopic tumor only and evaluate the pathologic significance of that residual tumor.
III. Determine the local control rates in patients with clinical group III disease treated with response-adjusted radiotherapy doses after second-look surgical resection.
OUTLINE: This is a nonrandomized, multicenter study. Patients are assigned to 1 of 2 treatment regimens according to disease stage and clinical group.
REGIMEN I (subset 1 patients) [closed to accrual as of 08/13/2010: Patients receive VAC chemotherapy comprising vincristine IV over 1 minute on day 1 of weeks 1-9 and dactinomycin IV over 1 minute and cyclophosphamide IV over 1 hour on day 1 of weeks 1, 4, 7, and 10; VA chemotherapy comprising vincristine IV over 1 minute on day 1 of weeks 13-21 and dactinomycin* IV over 1 minute on day 1 of weeks 13, 16, 19, and 22; and radiotherapy**, 5 days a week, beginning on week 13 and continuing for 4-7 weeks, depending on prescribed dose.
REGIMEN II (subset 2 patients)[closed to accrual as of 9/23/2011]: Patients receive VAC chemotherapy and radiotherapy** as in regimen I and VA chemotherapy comprising vincristine IV over 1 minute on day 1 of weeks 13-21, 25-33, and 37-45 and dactinomycin* IV over 1 minute on day 1 of weeks 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, and 46. Patients with clinical group III disease may undergo second-look surgery at week 13 followed by response-adjusted radiotherapy, and continued VA* chemotherapy. In both regimens, treatment continues in the absence of disease progression or unacceptable toxicity.
NOTE: *For both regimens, dactinomycin is omitted during radiotherapy.
NOTE: **Clinical Group I tumors and those with Clinical Group III uterine/cervix primary disease with negative nodes who have undergone a complete resection (i.e. hysterectomy) at Week 13 do not receive radiotherapy at Week 13
Patients are followed up every 3 months for 1 year, every 4 months for 2 years, every 6 months for 1 year, and then annually thereafter.

Experimental: Regimen I (chemotherapy, radiotherapy)
Patients receive VAC chemotherapy comprising vincristine sulfate IV over 1 minute on day 1 of weeks 1-9 and dactinomycin IV over 1 minute and cyclophosphamide IV over 1 hour on day 1 of weeks 1, 4, 7, and 10; VA chemotherapy comprising vincristine sulfate IV over 1 minute on day 1 of weeks 13-21 and dactinomycin IV over 1 minute on day 1 of weeks 13, 16, 19, and 22 (dactinomycin is omitted during radiation therapy); and radiation therapy, 5 days a week, beginning on week 13 and continuing for 4-7 weeks, depending on prescribed dose. Some patients do not receive radiation therapy; some start it at week 24. (closed to accrual as of 08/13/2010)

- Cumulative Incidence of Patients Who Receive Reduced Doses of Radiation Therapy [ Time Frame: From enrollment up to 5 years ]The local failure rate will be estimated using cumulative incidence curves.
- Percentage of Patients With Delayed Surgical Procedures [ Time Frame: At 13 weeks after induction ]The decision to perform second-look surgery should be based on the physical examination and imaging studies at Week 12 and should only be considered if a reasonable functional and cosmetic result is anticipated.
- Cumulative Incidence of Group III Patients Who Received With Reduced Radiotherapy Dose [ Time Frame: From enrollment up to 20 weeks ]The local failure rate will be estimated using cumulative incidence curves for Group III patients who received reduced doses of radiation therapy after second look surgical resection.
