HealthDay News — Incidence rates of testicular germ cell tumors have increased among young hispanics in the United States, according to researchers.
“Although rising incidence rates of testicular germ cell tumors have been well documented in white men, relatively little is known about rates in men of hispanic origin,” wrote Franklin L. Chien, BA, of the University of Washington in Seattle, and colleagues in Cancer.
To compare the incident of testicular germ cell tumors in white men of hispanic and non-hispanic origin, the investigators analyzed data from the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program.
The annual incidence of testicular germ cell tumors among hispanic patients 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% increase).
During the same time period, the incidence among non-hispanic white young adult patients increased from 12.41 to 13.22 cases per 100,000 (7% 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,” wrote the researchers. “Similar trends were not observed in non-Hispanic whites.”
