Understanding the role of urology practice organization and racial composition in prostate cancer treatment disparities.
This study examined the associations between urology practice organization and racial composition and treatment patterns for Medicare beneficiaries with incident prostate cancer. The authors used a 20% sample of national Medicare data to identify beneficiaries diagnosed with prostate cancer between January 2010 and December 2015 and followed them through 2016. They then linked urologists to their practices with tax identification numbers and patients to their practices based on their primary urologist. They identified 54,443 patients with incident prostate cancer, with most (87%) White and 9% Black. They found wide variation in racial practice composition and practice segregation. Patients in practices with the highest proportion of Black patients had the lowest socioeconomic status (43.1%), highest comorbidity (9.9% with comorbidity score ≥ 3), and earlier age at prostate cancer diagnosis (33.5% age 66-69 years). Black patients had lower odds of definitive therapy and underwent less treatment than White patients in every practice context. Black patients had lower predicted probability of treatment (66%) than White patients (69%).

Factors influencing prostate cancer treatment decisions for African American and white men.
This prospective, population-based cohort study examined some possible reasons for mortality outcome differences for prostate cancer between African American (AA) and white patients. A cohort of 1170 men with nonmetastatic prostate cancer were enrolled from 2011 to 2013 before treatment in North Carolina. Participants were asked to rate their aggressiveness of their cancer, and also the importance of 10 factors their treatment decision-making process. Among low-risk patients, there was no difference in perception of their cancer as “not very aggressive”. Among high-risk patients, 54% of AA patients considered their cancer to be “not very aggressive” while only 24% of white patients did. For AA patients, cost, treatment time, and recovery time were considered very important more than white patients.
