BACKGROUND: Screening and diagnosis of prostate cancer (PCa) is hampered by an inability to predict who has the potential to develop fatal disease and who has indolent cancer. Studies have identified multiple genetic risk loci for PCa incidence, but it is unknown whether they could be used as biomarkers for PCa-specific mortality (PCSM). OBJECTIVE: To examine the association of 47 established PCa risk single-nucleotide polymorphisms (SNPs) with PCSM. DESIGN, SETTING, AND PARTICIPANTS: We included 10 487 men who had PCa and 11 024 controls, with a median follow-up of 8.3 yr, during which 1053 PCa deaths occurred. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The main outcome was PCSM. The risk allele was defined as the allele associated with an increased risk for PCa in the literature. We used Cox proportional hazards regression to calculate the hazard ratios of each SNP with time to progression to PCSM after diagnosis. We also used logistic regression to calculate odds ratios for each risk SNP, comparing fatal PCa cases to controls. RESULTS AND LIMITATIONS: Among the cases, we found that 8 of the 47 SNPs were significantly associated (p
