Epidemiology and Demographics
Ewing sarcoma is the second most common malignant bone tumor in patients younger than 20. The most frequent is osteosarcoma.[1]
Incidence
- The incidence of Ewing sarcoma has remained unchanged for 30 years.
- The overall incidence of Ewing sarcoma is 0.1 cases for 100,000 individuals.
- The incidence of Ewing sarcoma in children aged 10 to 19 years is 1 case for 100,000 individuals.
Race
- Incidence of Ewing sarcoma in the United States is nine times greater in whites than in African Americans, with an intermediate incidence in Asians.
- The relative paucity of Ewing sarcoma in people of African or Asian descent may be explained, in part, by a specific polymorphism.
- The polymorphism associated with the increased risk is found at a much higher frequency in whites than in blacks or Asians, possibly explaining the epidemiology of the relative infrequency of Ewing sarcoma in the latter populations.
- Caucasians more frequently develop Ewing's sarcoma than Asians. Also, African Americans and Africans rarely suffer from this disease. There was a study done between 1973 and 1985, and out of 650 cases only three of them were from African descent.[1]
Age
- Ewing sarcoma typically occurs in children and adolescents between 10 and 20 years of age (95% between 4 and 25 years of age).
- The median age of patients with Ewing sarcoma is 15 years.
- Well-characterized cases of Ewing sarcoma in neonates and infants have been described.
Gender
Men are slightly more affected with Ewing sarcoma than women.
