Temporal Trends in the Incidence of Testicular Cancer in the United States over the Past Four Decades.

Testicular cancer is the most commonly diagnosed solid-organ neoplasm among young men, with variable incidence across racial groups. Testicular cancer incidence has increased since the 1970s, most notably among white men. Such trends in testicular cancer remain poorly understood. We investigated age-adjusted incidence rates of testicular cancer from 1975 to 2015 using Surveillance, Epidemiology and End Results data to further understand the nature of the temporal trends and potential drivers of disease. Across this time period, white men had the highest incidence and the largest increase in rate; however, we also note more recent increases in the incidence of testicular cancer across all racial groups being examined. PATIENT SUMMARY: We analyzed the rate of testicular cancer in the United States between 1975 and 2015. In that time, white patients had the highest rate and increase in rate of testicular cancer, but non-white patients also had increasing rates of disease.
