Summary

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma.

Description

PRIMARY OBJECTIVES:

I. To evaluate the failure free survival (FFS) of patients with very low-risk (VLR) rhabdomyosarcoma (RMS) (fusion negative [FN], stage 1, clinical group [CG] I, MYOD1 wildtype [WT], TP53 [WT]) when treated with 24 weeks of vincristine and dactinomycin (VA).

II. To evaluate the FFS of patients with low-risk (LR) RMS (FN, stage 1 CG II, or stage 2 CG I/II or CG III [orbit only], MYOD1 WT, TP53 WT) when treated with 12 weeks of vincristine, dactinomycin and cyclophosphamide (VAC) followed by 12 weeks of VA.

SECONDARY OBJECTIVES:

I. To evaluate the overall survival (OS) of patients with VLR RMS treated with 24 weeks of VA.

II. To evaluate the OS of patients with LR RMS treated with 12 weeks of VAC followed by 12 weeks of VA.

III. To demonstrate the feasibility of central molecular risk stratification of patients with newly diagnosed RMS in the context of a prospective clinical trial.
