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