Racial and Socioeconomic Disparities in MRI-Fusion Biopsy Utilization to Assess for Prostate Cancer

Published:January 04, 2022DOI:https://doi.org/10.1016/j.urology.2021.11.040

      Abstract

      Objective

      To evaluate whether racial disparities in MRI-Bx usage persisted after correction for socioeconomic, demographic, and clinical factors.

      Methods

      This is a retrospective cohort study of patients who received either MRI-Bx or systematic biopsy (SB) within a single academic medical center between January 2018 - June 2020. For each patient, socioeconomic variables including household income, education, percent below poverty, and unemployment were estimated using 2015 American Community Survey census-tract level data. Chi-square analysis was used to examine differences in clinical and demographic characteristics between the two groups. The Benjamini-Hochberg procedure was used to control false discovery rate (FDR) for multiple testing.

      Results

      Eighteen percent of Black men (53/295) received MRI-Bx while 41% (228/561) of white men received MRI-Bx. Patients coming from highly impoverished areas were less likely to receive MRI-Bx, 25% vs 75%, respectively. In multivariate analysis, race remained significantly different across MRI-Bx and SB groups. Clinical factors including family history, DRE, BMI, and prostate volume were not significantly different between patients receiving MRI-Bx and SB.

      Conclusion

      Black men are less likely to receive MRI-Bx than white men, even after adjusting for clinical and socioeconomic characteristics. Further work is necessary to identify and study methods to increase equity in PCa diagnostic testing.
