Overview
Rhabdomyosarcoma is a relatively rare form of cancer. It is most common soft tissue sarcoma in children. The overall incidence of rhabdomyosarcoma in children is approximately 0.45 cases per 100,000 children. Rhabdomyosarcoma tends to affect individuals <45 Years.
Epidemiology and Demographics
Rhabdomyosarcoma is a relatively rare form of cancer. It is most common soft tissue sarcoma in children. It accounts for 5-8% of childhood cancers and and 19% of all pediatric soft tissue sarcomas.
Incidence
The overall incidence of rhabdomyosarcoma in children is 0.45 cases for 100,000 children and 50% of cases are seen in the first decade of life. 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
In general, rhabdomyosarcoma tends to affect individuals less than 45 years of age.
- Rhabdomyosarcoma is most commonly seen in children aged one to five years old. Overall, 65% of all rhabdomyosarcomas are diagnosed in patients under 10 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.
