Unveiling trends in urinary tract cancer mortality among older adults in the United States (1999-2022): a CDC WONDER perspective.

BACKGROUND

Urinary tract cancers (UTCs), including bladder cancer, remain a significant public health challenge, particularly among individuals aged 75 and older. Despite declining bladder cancer-specific mortality rates between 2015 and 2020, the broader trends in UTC mortality and associated demographic disparities remain underexplored.

METHODS

We analyzed mortality data from 1999 to 2022 using the CDC WONDER database. UTC deaths were identified using ICD- 10 codes C64 to C68. Age-adjusted mortality rates (AAMRs) per 100,000 population were calculated, stratified by sex, race/ethnicity, and census regions. Joinpoint regression identified annual percent changes (APCs) to assess temporal trends.

RESULTS

From 1999 to 2022, 477,157 UTC deaths were recorded, 66% of which occurred among individuals aged 75 and older. The AAMR increased from 97.1 in 1999 to 103.5 in 2022, with a rise between 1999 and 2007 (APC: 0.63%), a decline from 2007 to 2019 (APC: - 0.33%), and a resurgence from 2019 to 2022 (APC: 2.42%). Older males exhibited higher AAMRs than females (178.7 vs. 53.6 in 2022), and Whites had the highest AAMR (108.5) among racial groups. The Western region recorded the highest AAMR (84.3) during the study period.

CONCLUSION

The resurgence in UTC mortality post- 2019 highlights emerging challenges, particularly among older males, Whites, and residents of the Western region. Targeted interventions, including improved screening and equitable healthcare access, are essential to mitigate these disparities and improve outcomes.
