Ewing Sarcoma (EWS) is a rare and aggressive cancer that primarily affects children and young adults. This tumor can arise in bones or soft tissues and is particularly dangerous when it spreads to other parts of the body (metastasis) or returns after treatment (relapse), with survival rates dropping below 30%. No progress has been made for these patients in decades, despite ongoing clinical trials, and these patients are required to endure intense chemotherapy every other week with significant short- and long-term side effects.
