Rhabdomyosarcoma is the most common soft tissue sarcoma in infants and children. The peak incidence of rhabdomyosarcoma occurs in children between 2 and 5 years of age, and a second peak is seen in teenagers between 15 and 19 years of age. In the final report of 686 patients from the First Intergroup Rhabdomyosarcoma Study (IRS), the median age at diagnosis for a child presenting with rhabdomyosarcoma of any primary site was 7 years; 4% of patients were less than 1 year of age at presentation; 38% were younger than 5 years of age, and 63% were 10 years of age or younger.
