e17107 Background: Genitourinary (GU) cancers significantly impact United States (US) public health, not just in mortality but also in premature deaths. We evaluated the potential years of life lost (PYLL) due to these cancers (prostate, kidney, bladder, testicular, penile, and others) from 1975 to 2017 using the SEER database and stratified it across racial groups. Methods: From 1975 to 2017, GU cancers were identified using SEER*Stat 8.4.2 using ICD-10 CM codes. We analyzed premature deaths and calculated PYLL as Life expectancy minus (age at diagnosis + survival time). Due to non-homogeneity, the Kruskal-Wallis test (α = 5%) was employed for subgroup PYLL analysis. Spearman correlation coefficient (ρ) assessed the relationship between the year of diagnosis and PYLL. Analyses were conducted using SAS OnDemand. Results: Of the 1,715,763 GU cancer cases (1975-2017), 235,279 had premature deaths, totaling 2,406,551.20 PYLL. Testicular cancer showed the highest median PYLL (33.3 years) compared to other sites, followed by penile cancer with a median PYLL of 12.2 years. Non-Hispanic (NH) Blacks had higher PYLL for prostate, kidney, ureteral, and bladder cancers (p<0.05), while Hispanics had higher PYLL for penile and testicular cancers (p<0.0001). ρ value for PYLL and year of diagnosis was 0.23. Conclusions: Our study reveals a substantial impact of GU cancers on premature mortality and PYLL in the US. Despite the lower prevalence, testicular and penile cancers contribute significantly to PYLL, likely related to younger age at diagnosis. Racial disparities were evident, with NH-Blacks and Hispanics experiencing higher PYLL for specific GU cancers compared to other racial groups. These findings underscore the pressing need for targeted interventions to address disparities and enhance GU cancer management and prevention outcomes. Table: see text
