MONDAY, June 22 (HealthDay News) -- Ewing sarcoma disproportionately affects Caucasians, but outcomes are not affected by race, according to a study published online June 22 in Cancer.
Muhammad U. Jawad, M.D., of the University of Miami Miller School of Medicine, and colleagues analyzed 1,631 Ewing sarcoma cases from the Surveillance, Epidemiology, and End Results database that were diagnosed between 1973 and 2005.
The researchers found that the incidence of Ewing sarcoma per 100,000 population was highest among Caucasians (0.155), and that the incidence has increased among Caucasians since 1973. They also found that female sex was associated with a survival benefit among Caucasians, but not among other races. Incidence rates were significantly lower for Asians/Pacific Islanders and African Americans (0.082 and 0.017, respectively), and outcomes were similar between races.
"The current study constitutes a significant step toward identification of independent demographic and clinical factors associated with improved survival and clarifies some of the associated controversies in incidence patterns that could have an impact on the treatment of patients with Ewing sarcoma," the authors conclude.
