Bladder Cancer Incidence and Survival in the United States and Texas Non-Latino Whites and Latinos

Abstract

BACKGROUND: Bladder cancer (BC) poses an enormous burden on health care systems. Latinos in Texas (TX) were underrepresented in previous studies on racial/ethnic disparity of BC in the US. OBJECTIVE: To examine whether BC incidence and survival rates differ among Latinos compared to non-Latino whites (NLW) in South TX, TX, and the US SEER. METHODS: Data was collected from the US SEER Program and the Texas Cancer Registry. Annual age-specific and age-adjusted BC incidence rates and annual 5-year relative survival were calculated. RESULTS: South TX and TX had significantly lower BC incidence rates than SEER for both Latinos and NLW regardless of gender (Ps<0.05). South TX women had worse BC survival rates than SEER women for both Latinos and NLW (Ps<0.05). TX NLW had worse BC survival rates than SEER NLW for both genders together and men only (Ps<0.05). All Latino groups had lower incidence but worse survival rates than NLW groups for both men and women in each geographic area (all Ps<0.05). Women had significantly lower BC incidence but worse survival rates than men regardless of race/ethnicity in each geographic area (all Ps<0.05). CONCLUSIONS: South TX women had lower BC incidence but worse survival rates than US SEER women for both Latinos and NLW. Latinos had worse survival but lower incidence rates than NLW. Women had lower BC incidence but worse survival rates than men. The study identifies the BC distribution and high-risk population, racial/ethnic disparities, and geographic differences. It facilitates health care services planning.
