Differences in Use of Aggressive Therapy for Localized Prostate Cancer in New York City

Socioeconomic factors may impact how a patient is treated for prostate cancer (CaP). Our objective was to determine if county of residence or neighborhood socioeconomic characteristics were associated with treatment for CaP in New York City (NYC).

We used the NYSPACED database to identify men aged 40 to 80 years with localized CaP in NYC between 2004 and 2016. We categorized patients into receiving either aggressive local therapy (ALT) or non-aggressive treatment (NT). We identified borough of residence through NYSPACED and used Public Use Microdata Area (PUMA) designation to define neighborhood characteristics using United States Census data. We hypothesized that differences exist in use of ALT according to county of residence and neighborhood characteristics. We used multivariable logistic regression to test the association between county of residence and ALT as well as between ALT and PUMA characteristics.

Our cohort included 40,668 patients. Overall, 80% had ALT, and 21% had NT. NT use increased over time from 16% in 2004 to 32% in 2016 (P < .001). On multivariable logistic regression, patients in Manhattan were less likely to receive ALT compared with those in other boroughs (P < .001). PUMAs with lower education attainment, larger foreign-born populations, lower crime rate, and higher median income were significantly associated with receipt of ALT (P < .05).

We observed significant differences in use of treatment for men with newly diagnosed CaP in NYC. The ability to receive this treatment was associated with borough of residence as well as neighborhood socioeconomic characteristics. Additional research is required to identify barriers in access to NT within NYC.
