Benign prostatic hyperplasia: racial differences in treatment patterns and prostate cancer prevalence

Area of Science:

• Urology
• Oncology
• Health Disparities

Background:

• Benign prostatic hyperplasia (BPH) affects a large number of men.
• Racial disparities in health outcomes, particularly for prostate cancer, are a significant concern.

Purpose of the Study:

• To compare rates of prostate cancer, BPH-related surgery, and acute urinary retention between African American and Caucasian men over 11 years.
• To evaluate associated healthcare resource utilization in these populations.

Main Methods:

• A retrospective analysis of 398 African American and 1656 Caucasian men with BPH within a health maintenance organization.
• Time-to-event analysis was used to assess clinical outcomes, stratified by baseline prostate-specific antigen (PSA) levels.

Main Results:

• African American men had a 2.2 times greater risk of prostate cancer diagnosis compared to Caucasian men (P < 0.001).
• While African Americans were more likely to receive medical therapy for BPH, no significant differences were observed in acute urinary retention or BPH-related surgery rates.
• Monthly BPH-related medical charges were similar between racial groups (US $407 vs US $405).

Conclusions:

• African American men with BPH exhibit a substantially higher risk of developing prostate cancer.
• These findings underscore the critical need for targeted education and early detection strategies for prostate cancer in African American men.
• Real-world clinical practice data highlight significant racial disparities in prostate cancer risk among men with BPH.
