Abstract

Background: Understanding the characteristics of men who initially present with metastatic prostate cancer (mPCa) can better enable directed improvement initiatives. The objective of this study was to assess the relationship between socioeconomic status (SES) and newly diagnosed mPCa. Materials Methods: All men diagnosed with PCa in the National Cancer Data Base from 2004 to 2013 were identified. Characteristics of men presenting with and without metastatic disease were compared. A 4-level composite metric of SES was created using Census-based income and education data. Multivariable logistic regression was used to evaluate the association between SES, race/ethnicity, and insurance and the risk of presenting with mPCa at the time of diagnosis. Results: Of 1,034,754 patients diagnosed with PCa, 4% had mPCa at initial presentation. Lower SES (first vs. fourth quartile; odds ratio [OR] = 1.39, 95% CI: 1.35–1.44), black and Hispanic race/ethnicity (vs. white; OR = 1.47, 95% CI: 1.43–1.51 and OR = 1.22, 95% CI: 1.17–1.28, respectively), and having Medicaid or no insurance (vs. Medicare or private; OR = 3.91, 95% CI: 3.78–4.05) were each independently associated with higher odds of presenting with mPCa after adjusting for all other covariates. Conclusions: Lower SES, race/ethnicity, and having Medicaid or no insurance were each independently associated with higher odds of presenting with metastases at the time of PCa diagnosis. Our findings may partially explain current PCa outcomes disparities and inform future efforts to reduce disparities.
