- Intermediate-risk: Embryonal, botryoid, or spindle cell RMS Stage 2 or 3 and Group III; Alveolar, undifferentiated, or anaplastic RMS: Stage 1-3, group I-I; I)
- High-risk: Embryonal, botryoid, spindle cell, alveolar, undifferentiated, or anaplastic RMS with metastatic disease at diagnosis (stage 4).
- Participants treated on this protocol in the low or intermediate risk arm who experience disease progression prior to week 13 will transfer to the high risk arm and proceed with high risk chemotherapy starting at week 1 of the protocol.
- Age < 22 years (eligible until 22nd birthday)
- Performance level corresponding to ECOG score of 0, 1, or 2. The Lansky performance score should be used for participants < 16 years
- Participant has received no prior radiotherapy or chemotherapy for rhabdomyosarcoma (excluding steroids) unless an emergency situation requires local tumor treatment. Prior biopsy, surgical resection and lymph node sampling is allowed.
- Initiation of chemotherapy is planned within 6 weeks (42 days) of the definitive biopsy or surgical resection.
Adequate bone marrow function defined as:
- Peripheral absolute neutrophil count (ANC) ≥ 750/μL
- Platelet count ≥ 75,000/μL (transfusion independent)
- Adequate liver function defined as total bilirubin ≤ 1.5 x upper limit of normal (ULN) for age. Participants with biliary or hepatic primaries with bilirubin values greater than 1.5 x ULN may be enrolled on study if all other eligibility criteria are met.
Adequate renal function defined as:
- Creatinine clearance or radioisotope GFR ≥ 70 mL/min/1.732 or
- Serum creatinine based on age and gender
- Participants with urinary tract obstruction by tumor must meet the renal function criteria listed above AND must have unimpeded urinary flow established via decompression of the obstructed portion of the urinary tract.
- Patients requiring emergency radiation therapy are eligible for enrollment on this study.
- Females of child-bearing potential cannot be pregnant or breast-feeding. Female participants ≥ 10 years of age or post-menarchal must have a negative serum or urine pregnancy test within 24 hours prior to beginning treatment. Female participants who are breast feeding must agree to stop breast feeding.
- Sexually active patients of childbearing potential must be willing to use effective contraception during therapy and for at least 1 month after treatment is completed.
- No evidence of active, uncontrolled infection.
- All participants and/or their parents or legal guardians must sign a written informed consent.
Exclusion Criteria:
- Participants who fail to meet one or more of the inclusion criteria will be excluded.
Inclusion Criteria for Contrast-Enhanced Ultrasound (CEUS) Sub-Study:
- Newly diagnosis or suspected diagnosis of previously untreated participants with rhabdomyosarcoma (RMS). NOTE: Patients with suspected diagnosis of RMS may enroll on screening part of study but must have histologic diagnosis to enroll on treatment part of study.
- Must have either intermediate-risk or high risk disease.
- 0-21 years of age.
Exclusion Criterial for CEUS Sub-Study:
- Undergoing upfront surgical resection of the primary tumor.
- History of allergy to Optison(TM) contrast agent or blood products.

Lymph node sampling will take place pretreatment and pre-surgery. Participants receive 12 weeks of chemotherapy (vincristine, dactinomycin and cyclophosphamide). They are then evaluated to determine how the tumor responded to treatment. Twelve additional weeks of chemotherapy (vincristine and dactinomycin) is given, followed by evaluation for tumor response. No further treatment is given, and participants are observed closely. Myeloid growth factor is given if needed. Participants also receive ^1^1C-methionine as described in the intervention section.
Lymph node sampling will take place pretreatment and pre-surgery. Participants receive 12 weeks of chemotherapy (vincristine, dactinomycin, cyclophosphamide). The tumor is evaluated to determine how it responded to treatment. Radiation therapy and/or surgical resection is performed to destroy or remove the remaining tumor. Twelve additional weeks of chemotherapy (vincristine, dactinomycin, cyclophosphamide) is given, followed by evaluation for tumor response. If delayed for medical reasons, radiation therapy and/or surgical resection is done at this time. Participants then receive 16 weeks of additional chemotherapy (vincristine, dactinomycin and cyclophosphamide). No further treatment is given, and participants are observed closely. Myeloid growth factor will be given if needed. Participants also receive ^1^1C-methionine as described in the intervention section.

If delayed for medical reasons, radiation therapy and/or surgical resection is done at this time. Participants receive 16 weeks of chemotherapy (vincristine, dactinomycin, cyclophosphamide) followed by 12 weeks of maintenance treatment (bevacizumab, sorafenib, oral cyclophosphamide). No further treatment is given, and participants are observed closely. Myeloid growth factor is given if needed. Participants also receive ^1^1C-methionine as described in the intervention section.
Lymph node sampling takes place pretreatment and pre-surgery. Participants receive 6 weeks (2 cycles) chemotherapy (vincristine and irinotecan). The tumor is evaluated for treatment response. 3 cycles of chemotherapy [vincristine, doxorubicin, cyclophosphamide/ifosfamide, etoposide (or etoposide phosphate) (VDC/IE)] are given. Dexrazoxane is given prior to each dose of doxorubicin. Radiation therapy begins at week 4 or 20 (depending on tumor location) while receiving vincristine and irinotecan. 2 cycles of VDC/IE, 4 cycles of modified vincristine, dactinomycin, cyclophosphamide (VAC), then 2 cycles of modified vincristine/irinotecan (total of 54 weeks). High risk participants also receive additional maintenance therapy beginning week 55 with anti-angiogenic chemotherapy (bevacizumab, sorafenib, cyclophosphamide). Myeloid growth factor is given as needed. Participants also receive ^1^1C-methionine as described in the intervention section.
