The effect of race on treatment patterns and subsequent health-related quality of life outcomes in men undergoing treatment for localized prostate cancer

Introduction Racial differences in Health-Related Quality of Life (HRQoL) after treatment of prostate cancer (PCa) are not well studied. We compared treatment patterns and HRQoL in African American (AA) and non-AA men undergoing active surveillance (AS), radical prostatectomy (RP), or radiation (XRT). Methods Men diagnosed with PCa from 2007–2017 in the Center for Prostate Disease Research Database were identified. HRQoL was evaluated using Expanded PCa Index Composite and SF-36 Health Survey. Results In 1006 men with localized PCa, 223 (22.2%) were AA (mean follow up 5.2 yrs). AA men with low-risk disease were less likely to undergo AS (28.5 vs. 38.8%) and more likely to undergo XRT (22.3 vs. 10.6%) than non-AA men, p < 0.001. In intermediate-risk disease, AA received more XRT (43.0 vs. 26.9%) and less RP (50.5 vs 66.8%), p = 0.016. In all men, RP resulted in worse urinary function and sexual HRQoL compared to AS and XRT. Bowel HRQoL did not vary by treatment in AA men, however, in non-AA men, XRT resulted in worse bowel scores than AS and RP. HRQoL was then compared for each treatment modality. AA men had worse sexual bother ( p = 0.024) after RP than non-AA men, No racial differences were found in urinary, bowel, hormonal, or SF-36 scores for men undergoing AS, RP or XRT. Conclusion AA men are less often treated with AS for low-risk disease and are more likely to undergo XRT. AA men experience worse sexual bother after RP, however, the effect of XRT on bowel symptoms is worse in non-AA men.
