(HealthDay News) — Incidence rates of testicular germ cell tumors have been increasing among young Hispanics in the United States, according to research published online July 14 in Cancer.
Franklin L. Chien, of the University of Washington in Seattle, and colleagues analyzed data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program. The authors sought to compare the incidence of testicular germ cell tumors in white men of Hispanic and non-Hispanic origin.
The researchers found that the annual incidence of testicular germ cell tumors among Hispanics, aged 15 to 39 years, increased significantly from 7.18 cases per 100,000 in 1992 to 11.34 cases per 100,000 in 2010 (58 percent increase). During the same time period, the incidence among non-Hispanic white young adults increased from 12.41 to 13.22 cases per 100,000 (7 percent increase). The incidence rates for testicular germ cell tumors among young Hispanics increased in metropolitan areas for both seminoma and nonseminoma subtypes and for all stages at diagnosis.
“There has been a recent substantial increase in testicular germ cell tumor incidence among Hispanic adolescents and young adults in the United States,” the authors write. “Similar trends were not observed in non-Hispanic whites.”
