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. In the current study, the authors compared germ cell tumor trends between men of Hispanic and non-Hispanic origin as a function of age at diagnosis.
Trends in testicular germ cell tumor incidence among white men were analyzed according to Hispanic ethnicity in 2 data sets of the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, spanning from 1992 to 2010 and from 2000 to 2010 and sampling 15% and 28% of the United States population, respectively. Rates were age-adjusted to the year 2000 US standard population.
Between 1992 and 2010, the annual incidence of testicular germ cell tumors among Hispanic whites ages 15 to 39 years increased 58%, from 7.18 cases per 100,000 in 1992 to 11.34 cases per 100,000 by 2010 (P<1 × 10−9). Their incidence rates increased in metropolitan areas for both seminoma and nonseminoma subtypes and for all stages at diagnosis. During the same 19-year interval, incidence among non-Hispanic white young adults increased 7%, from 12.41 to 13.22 per 100,000. During the 2000 to 2010 interval, no significant trends were observed in incidence among non-Hispanic whites.
There has been a recent substantial increase in testicular germ cell tumor incidence among Hispanic adolescents and young adults in the United States. Similar trends were not observed in non-Hispanic whites. Cancer 2014;120:2728–2734. © 2014 American Cancer Society.
