37 Background: This study compared 5-year health-related quality of life (HRQoL) outcomes among prostate cancer (PCa) patients who underwent a robotic-assisted radical prostatectomy (RARP) versus a radical retropubic prostatectomy (RRP), with a focus on race-specific outcomes for Caucasian American (CA) compared to African American (AA) men. RARPs have almost replaced RRPs in recent years, with few long-term studies focused on HRQoL and race. Methods: A prospective cohort study of HRQoL was conducted on patients diagnosed with PCa from 2007 to 2017 and enrolled in the Center for Prostate Disease Research (CPDR) Multicenter National Database. HRQoL was assessed with the EPIC instrument. Temporal changes in urinary and sexual-related quality of life domain scores were compared across surgery type (RARP versus RRP) at pre-treatment (“baseline”), 1-, 2-, 3-, 4-, and 5 years post-baseline. Longitudinal HRQoL patterns were modeled using generalized estimating equations (GEE), adjusting for baseline HRQoL and key clinical characteristics. Results: Of 497 PCa patients who met study inclusion criteria, 68% had RARP and 32% had RRP, with 22% AA men and 88% CA men. Baseline HRQoL domains were comparable across race and surgery type. In adjusted GEE analysis, no differences were noted between AA and CA patients. However, treatment-related differences were observed over time in urinary function (UF) and incontinence (UI) (p=0.02 and p=0.03, respectively), with lower HRQoL scores in RARP vs. RRP patients. Upon dual stratification by surgery type and race, the differences for UF and UI persisted (p=0.01 and p=0.03, respectively) with poorest outcomes observed, and similar trajectories of decline, for AA patients who received RARP. Conclusions: In this 10+ year prospective cohort study, AA patients receiving RARP had the poorest UF and UI outcomes which continued to decline for 5 years post treatment. In light of these findings, AA men considering RARP might benefit from discussions with their providers to set expectations regarding long-term urinary outcomes; though these decrements in HRQoL may be overshadowed by the minimally invasive nature of RARP.
