PURPOSE: To review and summarize the reported health disparities and inequities in diagnostic imaging for prostate cancer.
METHODS: We queried the PubMed search engine for original publications studying disparate utilization of diagnostic imaging for prostate cancer. Query terms were as follows: prostate AND cancer AND diagnostic AND imaging AND (magnetic resonance imaging (MRI) OR computed tomography (CT) OR bone scintigraphy OR positron emission tomography (PET)-CT)) AND (inequities OR disparities OR socioeconomic OR race). Studies were included if they involved United States patients, had diagnostic imaging as a part of their care, and addressed health inequities.
RESULTS: A total of 104 studies were captured in the initial query with 17 meeting inclusion criteria, comprising 10 population-based analyses, 5 single institutional analyses, 1 multi-institutional analysis, and 1 review. Socioeconomic status and race were frequently associated with imaging utilization and guideline-concordant care. SEER analyses revealed that African-American men had higher odds of experiencing overuse of pelvic CT/pelvic MRI and bone scans, while older men experienced underuse. Higher income and younger age were more likely to receive imaging that was adherent to NCCN guidelines. African-American and Hispanic men were less likely than white men to receive prostate multiparametric MRI.
CONCLUSION: Race, age, and socioeconomic status play a significant role in the diagnostic management of prostate cancer. Certain demographics are more disparately affected and less likely to receive guideline-concordant care. Continued research and interventions are needed to ensure appropriate and accessible diagnostic imaging for prostate cancer and ultimately the delivery of quality and equitable care.
