Abstract

Abstract: Objectives: Black men are more likely to die of prostate cancer (PCa) than White men. Whether this difference is driven by biological versus sociodemographic and access to care differences is actively investigated. However, studies that have highlighted racial disparities in PCa outcomes have been poorly represented by elderly men, a notoriously undertreated group. Herein, we evaluated use of curative treatment between Black and White elderly men with aggressive PCa in a large US database. Methods: Men ≥80 years diagnosed with National Comprehensive Cancer Network-defined high risk PCa between 2004 and 2016 were analyzed from the National Cancer Database. Multivariable logistic regression was used to model the effect of race and sociodemographic factors on receipt of definitive therapy (surgery or radiation +/− androgen deprivation therapy [ADT]) versus non-definitive therapy (ADT alone or observation) in inverse probability weighted groups matched for stage, prostate-specific antigen, and Gleason score. Results: Between 2004 and 2016, utilization of definitive therapy with either surgery or radiation therapy increased in both White and Black men in the United States. However, we found that Black men compared with White men were significantly less likely to receive definitive therapy (OR 0.71, 95% CI 0.64–0.79, p < .001). Using multivariable modeling, effect size diminished after adjusting for sociodemographic variables. Notably, there is evidence of the racial disparity narrowing over time. Conclusions: These findings highlight striking but improving racial disparities in elderly men with high risk PCa in the US, an overall undertreated population.
