Overview
Epidemiology and Demographics
Rhabdomyosarcoma is a relatively rare form of cancer. It is most common soft tissue sarcoma in children.
Incidence
Incidence may depend on the histologic subtype of rhabdomyosarcoma:
- Embryonal rhabdomyosarcoma: Embryonal rhabdomyosarcoma peaks in 0 to 4 year age group at approximately 0.4 cases per 100,000 children, with a lower rate in adolescents, approximately 0.15 cases per 100,000 adolescents.
- Alveolar rhabdomyosarcoma: The incidence of alveolar rhabdomyosarcoma does not vary by gender and is constant from ages 0 to 19 years at approximately 0.1 case per 100,000 children and adolescents.
- Undifferentiated sarcoma: Infants younger than 1 year have a higher incidence of undifferentiated sarcoma.
Age
- Rhabdomyosarcoma is most commonly seen in children aged one to five years old.
- Less commonly, it can also present in teens aged 15 to 19, and can even develop in adulthood, though this is even more rare.
- The incidence is 0.45 cases for 100,000 children and 50% of cases are seen in the first decade of life.
