摘要: Importance Few studies have evaluated the association between a single-nucleotide polymorphism–based genetic risk score (GRS) and patient age at prostate cancer (PCa) diagnosis. Objectives To test GRS PCa diagnosis to compare performance of with that family history (FH) in stratification. Design, Setting, Participants A cohort study 3225 white men was conducted as secondary analysis Reduction by Dutasteride Prostate Cancer Events (REDUCE) chemoprevention trial, 4-year, randomized, double-blind, placebo-controlled multicenter from March 2003 April 2009 evaluate safety efficacy dutasteride reducing events. were confirmed be free biopsy (6-12 cores) within 6 months prior underwent 10 core biopsies every 2 years per protocol. The dates for performing data July 2016 October 2019. Interventions well-established, population-standardized calculated each participant based on 110 known risk–associated polymorphisms, which is relative compared general population. Men classified into 3 groups predetermined cutoff values: low ( Main Outcomes Measures diagnosis–free survival among different groups. Results Among (median age, 63 [interquartile range, 58-67 years]) study, 683 (21%) risk, 1937 (60%) average 605 (19%) high alone. In comparison, 2789 (86%) or 436 (14%) FH higher had rate worse than those lower group (χ2 = 53.3;P 80 years) more (95% CI, >80 risk. contrast, median 73 71-76 positive 77 76-79 negative FH. Conclusions Relevance This suggests significantly associated Combining may better stratify inherited alone developing personalized screening strategies.
