AB - Late bladder toxicity is a concern for patients receiving prostate cancer radiotherapy and negatively impacts survivors. Few risk factors are known beyond the radiation dose and volume of bladder exposed. A polygenic risk score (PRS) could identify susceptible patients.A PRS was built using genome-wide association results from the Radiogenomics Consortium (N=3,988), then tested in the prospective REQUITE and URWCI studies (N=2,034). The primary outcome was time-to-patient-reported gross (≥ grade 2, G2) hematuria analyzed using Cox proportional hazards regression. Secondary outcomes were ≥G2 urinary retention and frequency. The PRS was externally validated for clinically-diagnosed irradiation cystitis in the UK Biobank (N=8,430). A gene-burden test evaluated rare coding variants.A 115-variant PRS was associated with significantly increased risk of ≥G2 hematuria (hazard ratio [HR] per standard deviation [SD]=1.22, p=0.009) as well as urinary retention (HR-per-SD=1.18, p=0.016) and frequency (HR-per-SD=1.14, p=0.036). When binarized, men in the upper decile (PRShigh) had >2-fold increased risk of hematuria after adjusting for clinical risk factors (HR=2.12, p=0.002; Harrel's c-index 0.71 [95
