Background
While overall pediatric cancer patient survival rates have significantly improved over the past 40 years, poor prognosis persists in the aggressive pediatric cancer, alveolar rhabdomyosarcoma (aRMS). aRMS survival rates for high risk groups have not significantly improved in decades, due to an incomplete understanding of the underlying disease mechanisms. Many aRMS tumors harbor an aRMS-specific gene mutation, known as PAX3-FOXO1. However, using experimental approaches, this mutation alone is not sufficient for tumor formation.
