Volume 22, Number 4Review ArticlesLow Penetrance Germline Genetic Testing: Role for Risk Stratification in Prostate Cancer Screening and Examples From Clinical PracticeManagement UpdateGerald L AndrioleFranklin GaylisKelly K BreePaul DatoChristopher J KaneA Karim KaderBroad-based prostate-specific antigen (PSA) screening has saved lives but at a substantial human and financial cost. One way of mitigating this harm, while maintaining and possibly improving the benefit, is by focusing screening efforts on men at higher risk. With age, race, and family history as the only risk factors, many men lack any reliable data to inform their prostate cancer (PCa) screening decisions. Complexities including history of previous negative biopsies, interpretation of negative and/or equivocal mpMRI findings, and patient comorbidities further compound the already complicated decisions surrounding PCa screening and early detection. The authors present cases that provide real-world examples of how a single nucleotide polymorphism–based test can provide patients and providers with personalized PCa risk assessments and allow for development of improved risk-stratified screening regimens.
