Brief Summary
This phase III trial compares higher dose chemotherapy, with vincristine, dactinomycin and cyclophosphamide, over a shorter amount of time to lower dose chemotherapy plus maintenance, with vincristine, dactinomycin, cyclophosphamide, irinotecan and vinorelbine, over a longer amount of time, along with standard of care surgery and radiation, in patients with newly diagnosed intermediate risk rhabdomyosarcoma. Vincristine and vinorelbine are in a class of medications called vinca alkaloids. They work by stopping tumor cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy (antineoplastic antibiotic). It works by damaging the cell's DNA and may kill tumor cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells. It may also lower the body's immune response. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. It is not yet known if the higher dose chemotherapy over a shorter amount of time or the lower dose chemotherapy with maintenance over a longer amount of time is more effective in the treatment of patient with newly diagnosed, intermediate risk rhabdomyosarcoma.
Brief Title
A Study Comparing Higher Dose Chemotherapy Over a Shorter Amount of Time to Lower Dose Chemotherapy Plus Maintenance Over a Longer Amount of Time in Patients With Newly Diagnosed Intermediate-Risk Rhabdomyosarcoma (IR RMS)
Detailed Description
PRIMARY OBJECTIVE:
I. To determine if the event free survival (EFS) of patients with intermediate risk rhabdomyosarcoma (IR RMS) treated with surgery, radiotherapy, and vincristine, dactinomycin, cyclophosphamide (VAC) (2.2 g/m\^2/cycle cyclophosphamide) chemotherapy (regimen A) is better than that of patients treated with surgery, radiotherapy, and VAC alternating with vincristine, irinotecan (VI) (VAC/VI) (1.2 g/m\^2/cycle cyclophosphamide) chemotherapy plus 24 weeks of maintenance chemotherapy with vinorelbine and cyclophosphamide (regimen B).
SECONDARY OBJECTIVES:
I. To determine if the overall survival (OS) of patients with IR RMS treated with surgery and/or radiotherapy, and VAC (2.2 g/m\^2/cycle cyclophosphamide) chemotherapy (regimen A) is better than the OS of patients treated with surgery, radiotherapy, and VAC alternating with VI (VAC/VI) (1.2 g/m\^2/cycle cyclophosphamide) plus 24 weeks of maintenance chemotherapy with vinorelbine and cyclophosphamide (regimen B).
II. To compare clinician-reported treatment-related adverse event (AE) rates between two regimens.
III. To determine what proportion of patients deemed eligible for delayed primary excision (DPE) on retrospective central review undergo DPE and to assess the concordance of DPE eligibility between the central review and local site.
IV. To compare the 4-year local failure (LF) rate of patients deemed DPE-eligible by retrospective central review who undergo DPE with the 4-year LF rate of patients deemed DPE-eligible by central review who do not undergo DPE.
V. To determine the feasibility of reporting diagnostic tumor molecular features identified via the Molecular Characterization Initiative (MCI) within 6 weeks of treatment initiation for clinical group III patients.
EXPLORATORY OBJECTIVES:
I. To prospectively evaluate the following somatic molecular features (PAX3 or PAX7 and FOXO1 fusion, MYCN amplification, TP53 mutation, MYOD1 mutation, CDK4 amplification) via MCI and determine their association with EFS and OS.
II. To explore the relationship between methylation patterns in IR RMS and EFS and OS.
III. To test the use of digital pathology/artificial intelligence to refine the diagnosis of IR RMS.
IV. To assess the differential impact of regimen intensity on gonadal toxicity experienced by patients.
V. To determine the proportion of patients having fertility discussions and fertility preservation procedures prior to starting treatment.
VI. To collect biospecimens for patient-derived xenograft (PDX) RMS model generation.
VII. To bank biospecimens for future research. VIII. To evaluate the association between Household Material Hardship (HMH) measures and EFS and OS.

FOXO1 fusion status must be determined prior to enrollment. RMS types included under embryonal rhabdomyosarcoma (ERMS) include those which are reclassified in the 2020 World Health Organization (WHO) classification as ERMS (typical, dense and botryoid variants) and spindle cell/sclerosing RMS (encompassing the historical spindle cell ERMS variant and the newly recognized sclerosing RMS variant). Classification of alveolar Rhabdomyosarcoma (ARMS) in the 2020 WHO Classification is the same as in the International Classification of Rhabdomyosarcoma (ICR) and includes classic and solid variants.
* FOXO1 fusion negative (FN)

FOXO1 fusion results should be SUBMITTED as an upload to RAVE at study enrollment because this information is required for randomization.
Please note the following:
* Institutional PAX3 versus (vs.) PAX7 determination is not required but should be submitted if available. Institutional FOXO1 testing may be performed at a contract or commercial lab as long as reports can be submitted and uploaded to RAVE. Additional molecular pathology reports, including the MCI report, are not required but should be submitted if available.
* Patients who are \< 10 years old with distant metastatic disease (Stage 4) who have institutional molecular testing indicating fusion negative (FN) RMS but are later found to have fusion positive (FP) RMS by MCI or other testing will be considered to have metastatic FP disease and will go off study
