Testicular cancer rates for young Hispanic American men have risen dramatically in recent years, according to a study published online in the American Cancer Societys journal Cancer.
The researchers analyzed trends in testicular cancer rates in two datasets of the National Cancer Institutes Surveillance, Epidemiology and End Results program. The datasets spanned 1992 to 2010 and 2000 to 2010 and sampled 15% and 28% of the U.S. population, respectively.
The investigators found that between 1992 and 2010, the annual incidence of testicular germ cell tumors in 15- to 39-year-old Hispanic white men increased 58% from 7.18 cases per 100,000 in 1992 to 11.34 cases per 100,000 by 2010. Incidence rates increased in metropolitan areas for different subtypes of testicular cancer and for all stages of disease at the time of diagnosis. In the same 19-year interval, testicular germ cell tumor incidence among non-Hispanic white men increased 7%, from 12.41 to 13.22 per 100,000. During the 2000 to 2010 interval, incidence rates rose in Hispanic white men but no significant trends were observed in incidence rates among non-Hispanic white men, according to a news release.
The researchers noted that, historically, non-Hispanic white men have had the highest rate of testicular cancer of all racial and ethnic groups in the U.S.; however, this studys findings suggest that if the current trends continue, the rate of testicular cancer among Hispanic Americans will outpace that of non-Hispanic white men within the next few years, according to a news release.
Hispanic Americans comprise the fastest growing ethnic group in the U.S., Rebecca Johnson, MD, of Seattle Childrens Hospital, study co-author said in the release. Until only recently, cancer incidence data for this population has been too sparse to accurately analyze testicular cancer trends among Hispanic men. The increasing rate of testicular cancer in adolescent and young adult Hispanic males, combined with the rapid expansion of the Hispanic population in the U.S., is projected to have a measurable impact on the U.S. healthcare system.
The findings indicate that greater awareness is needed concerning the increasing risk of testicular cancer in Hispanic adolescents and young adults, and that research efforts are needed to determine the cause of this trend, according to the release.
