Introduction: To evaluate the impact of prostate cancer screening guidelines on different racial and ethnic populations.
Materials and methods: Data was collected from the 2005-2015 Surveillance, Epidemiology, and End Results (SEER) program. Incidence of prostate cancer diagnosis was categorized and analyzed by stage, race/ethnicity, and age group. Appropriate univariate and multivariable statistical analysis was performed.
Results: The odds of being diagnosed with regional-stage prostate cancer in 2013-2015 were 1.3 times higher for black men, 1.3 times higher for Asian American/Pacific Islander (AAPI) men, and 1.2 times higher for white men when compared to 2005-2008. The odds of being diagnosed with distant-stage prostate cancer in 2013-2015 were 1.6 times higher for black men, 1.8 times higher for AAPI men, and 2.1 times higher for white men when compared to 2005-2008. In 2005-2008, 2009-2012, and 2013-2015 respectively, the odds of being diagnosed with distant-stage prostate cancer were 1.8 times higher, 1.7 times higher, and 1.4 times higher for black men compared to white men, and 1.5 times higher, 1.5 times higher, and 1.4 times higher for AAPI men compared to white men (all respective p < .001).
Conclusions: The proportion of late-stage prostate cancer has increased significantly in all US males regardless of race and/or ethnicity. From 2013-2015, all men had a higher chance of being diagnosed with regional or distant stage disease compared to years prior. Newly-diagnosed regional-stage disease increased the most over time in AAPI and black men, while distant prostate cancer increased the most over time in white men.
