Testicular Cancer Incidence and Mortality Within Rural and Urban Regions

Purpose: Testicular cancer (TCa) is among the most common cancers within adolescent and young adult (AYA) male populations. However, information is limited to variations in incidence and mortality outside of racial/ethnic subgroups. Rural regions historically have a greater overall cancer incidence than urban regions, although some key differences exist regarding site. TCa-specific incidence and mortality disparities are not commonly reported in this context. This study aims to help fill that gap by providing discovery evidence if there is an association between US rural/urban regions and TCa incidence and mortality. Methods: Secondary analysis of Surveillance, Epidemiology, and End Results incidence and mortality data were employed to determine if rural/urban TCa incidence and mortality disparities exist among U.S. males. Results: There was a 2.6% increased rate of TCa in U.S. urban as compared with rural geographic regions from 2011 to 2015. When geographic region is disaggregated, rural regions see higher rates than urban. When factoring in race/ethnicity, White/Caucasians and Hispanics had statistically higher urban rates whereas American Indian/Alaskan Natives and Asian/Pacific Islander groups had statistically higher rural rates. Conclusion: Geographic regional TCa variation research is virtually nonexistent for U.S. males, specifically AYAs of color. Determining preliminary trends in rural and urban regions can assist in the creation of more targeted services, particularly among underserved and vulnerable populations that have tenuous access to health care, to reduce disparate health outcomes. Exploring geographic differences in TCa incidence and mortality can have implications within service industry, health care accessibility, and public health justice areas of research and outreach.
