Summary

This study will treat participants with newly diagnosed, low, intermediate and high risk rhabdomyosarcoma (RMS) using multi-modality risk-adapted therapy with standard or intensified dose chemotherapy, radiation and surgical resection. Intermediate and high risk participants will receive an additional 12 weeks (4 cycles) of maintenance therapy with anti-angiogenic chemotherapy.

PRIMARY OBJECTIVE:

* Estimate event-free survival for intermediate risk participants treated with vincristine, dactinomycin and cyclophosphamide with the addition of maintenance anti-angiogenic therapy.

SECONDARY OBJECTIVES:

* Estimate the false negative rate and incidence of additional positive lymph nodes in participants undergoing sentinel lymph node biopsy followed by limited nodal dissection.
* Maintain a high local control rate in participants treated with surgery and/or limited volume proton and photon radiation without dose escalation.
* Define the incidence and type of failure in participants who receive risk-adapted local therapy relative to the primary tumor volume.
* Establish the feasibility of delivering 4 cycles of maintenance anti-angiogenic chemotherapy in intermediate and high risk patients following standard chemotherapy.
* Estimate the event free survival for high risk patients receiving interval dose compressed therapy and maintenance anti-angiogenic therapy.
* Define the incidence of CTC grade 3 and higher toxicities (and specific grade 1-2 toxicities) related to proton beam therapy.

Conditions

  • Rhabdomyosarcoma

Interventions

DRUG

Vincristine

Dosage and route of administration: * \< 1 year of age=0.025 mg/kg intravenously (IV) * \> 1 year and \< 3 years= 0.05 mg/kg IV * ≥ 3 years=1.5 mg/m\^2 IV. Maximum dose 2 mg in all participants.

DRUG

Dactinomycin

Dosage and route of administration: * \< 1 year=0.025 mg/kg IV push * ≥ 1 year=0.045 mg/kg IV push over 1 to 5 minutes.

DRUG

Cyclophosphamide

Dosage and route of administration: During VAC chemotherapy: * \< 3 years of age = 40 mg/kg IV * ≥ 3 years of age = 1200 mg/m\^2 IV, with MESNA. During maintenance for intermediate-risk participants: * oral cyclophosphamide 50 mg/m\^2/dose/day (liquid or tablet)

PROCEDURE

Surgical Resection

Surgery will be performed for the primary site tumor with the goal of removing tumor cells while maintaining function in the organ or adjacent organs involved.

PROCEDURE

Radiation

Radiation therapy will be delivered at approximately week 13 (intermediate risk) or week 19 (high risk) after initiation of chemotherapy. Certain patients will receive radiation at week 4.

DRUG

Bevacizumab

Dosage and route of administration: 15 mg/kg/dose/day IV.

DRUG

Sorafenib

Dosage and route of administration: 90 mg/m\^2/dose twice daily.

DRUG

Myeloid Growth Factor

If a participant's chemotherapy has been delayed or modified for hematologic toxicity, or if participant experiences a significant life-threatening toxicity due to bone marrow suppression, myeloid growth factor (either filgrastim or peg-filgrastim) will be given per institutional practice. High Risk participants receive filgrastim 5 micrograms/kg/day (maximum 300 micrograms) subcutaneously beginning 24-36 hours after the last dose of chemotherapy. Continue at least 7 days, or until the ANC ≥750/µL whichever comes last. Sargramostim or peg-filgrastim may not be used.

PROCEDURE

Lymph Node Sampling

Clinical and/or imaging evaluation of regional lymph nodes will be conducted pretreatment and preoperatively as part of staging. This will aid in determining the efficacy of this procedure in defining involved lymphatics in "at risk" patients.

DRUG

Irinotecan

Dosage and Route Administration: During interval compressed therapy - irinotecan 50mg/m\^2 IV (maximum dose 100 mg/day) daily x 5.

DRUG

Ifosfamide

Dosage and Route of Administration: During interval compressed therapy - Age \> 1 year: 1800 mg/m\^2/day IV x 5 Age \<1 year: treat with 50% doses calculated on a m\^2 basis.

DRUG

Etoposide

Dosage and Route of Administration: Age \>1 year 100 mg/m\^2/day IV x 5 Age \< 1 year treat with 50% doses calculated on a m\^2 basis

DRUG

Etoposide Phosphate

Dosage and Route of Administration: Used in substitution for etoposide in participants who experience allergic reaction. It will be administered 100 mg/m\^2/day IV.

DRUG

Doxorubicin

Dosage and route of Administration: Age ≥1 year, 37.5 mg/m\^2 IV over 1 hour x 2 days Age \<1 year, 18.75 mg/m\^2 (i.e., a 50% dose reduction) IV over 1 hour x 2 days.

DRUG

Dexrazoxane

Dosage and Route of Administration: Dexrazoxane dose should be 10x that of doxorubicin. Age ≥1 year, 375 mg/m\^2 IV over 15-30 minutes Age \<1 year, 187l.5 mg/m\^2 (i.e., a 50% dose reduction) IV over 15-30 minutes.

DRUG

^1^1C-methionine

Participants receive \^1\^1C-methionine to relate the distribution, intensity and change in \^1\^1C-methionine CTPET imaging of the primary site to tumor control and patient outcome.
