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

Status: Active

Description

This phase II trial studies how well chemotherapy, surgery, and radiation therapy work in treating patients with newly diagnosed rhabdomyosarcoma that has spread to other parts of the body. Drugs used in chemotherapy, such as vincristine sulfate, dactinomycin, and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving combination chemotherapy and radiation therapy after surgery may kill any tumor cells that remain after surgery.

Trial Objectives and Outline

PRIMARY OBJECTIVE:

I. Estimate event-free survival for intermediate risk participants treated by vincristine sulfate, dactinomycin, cyclophosphamide (VAC) with the addition of maintenance anti-angiogenic therapy.

SECONDARY OBJECTIVES:

I. Estimate the false negative rate and incidence of additional positive lymph nodes in participants undergoing sentinel lymph node biopsy followed by limited nodal dissection.

II. Maintain a high local control rate in participants treated with surgery and/or limited volume proton and photon radiation without dose escalation.

III. Define the incidence and type of failure in participants who receive risk-adapted local therapy relative to the primary tumor volume.

IV. Establish the feasibility of delivering 4 cycles of maintenance antiangiogenic chemotherapy (bevacizumab/sorafenib [sorafenib tosylate]/low dose cyclophosphamide) in intermediate and high risk patients following standard chemotherapy.

V. Estimate the event-free survival for high risk patients receiving interval dose compressed therapy and maintenance anti-angiogenic therapy.

VI. Define the incidence of Common Toxicity Criteria (CTC) grade 3 and higher toxicities (and specific grade 1-2 toxicities) related to proton beam therapy.

EXPLORATORY OBJECTIVES:

I. Study the association between radiation dosimetry in participants receiving proton beam radiation therapy (PBRT) and musculoskeletal toxicity.

II. Compare dosimetrically, the ability of PBRT to spare adjacent normal tissues compared to photon-based radiation therapy.

III. Define the relation of distribution, intensity and change in carbon (C)11-methionine computed tomography positron emission tomography (CTPET) imaging of the primary site to local control and disease specific survival.

IV. Compare quantitative functional imaging parameters obtained in tumor and adjacent normal tissue at base line and following therapy with diffusion weighted imaging (DWI) and to local control and disease specific survival.

V. Evaluate if patterns of metabolic and functional imaging at baseline and response are consistent and reproducible to allow for the development of a biologically guided target volumes (BTV) for radiation therapy planning in subsequent trial.

VI. Evaluate the feasibility of contrast-enhanced ultrasound of primary tumors at baseline, day 7, and subsequent protocol driven imaging time-points during neoadjuvant therapy in intermediate and high-risk patients.

VII. Obtain tissue to better identify genetic subgroups of rhabdomyosarcoma.

VIII. Assess serial changes in genetic lesions during therapy and at recurrence.

IX. Assess potential of serum microribonucleic acid (RNA)-206 levels as biomarker of disease status.

X. Collect additional pharmacokinetic (PK) and pharmacogenomic (PG) datasets in a newly diagnosed patient population to further refine sorafenib PK models.

XI. Relate toxicities seen during the maintenance phase of therapy to sorafenib exposure levels.
