Risk-Adapted Focal Proton Beam Radiation and/or Surgery in Patients With Low, Intermediate and High Risk Rhabdomyosarcoma Receiving Standard or Intensified Chemotherapy

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.

About this study

Participants will be stratified based on both a pretreatment staging system and a post-surgery surgico/pathologic clinical grouping system. Treatment for low-risk (subset 1) participants will consist of chemotherapy and radiation. Low-risk (subset 2) and intermediate-risk participants will receive chemotherapy and radiation and/or undergo surgery to destroy/remove the tumor. Intermediate-risk participants will also receive 16 weeks of maintenance chemotherapy. High-risk participants will receive chemotherapy and radiation therapy. High-risk participants will also receive additional maintenance therapy with anti-angiogenic chemotherapy.
