Men with a germline pathogenic BRCA1 or BRCA2 variant have increased risks for developing breast, pancreatic, prostate, and melanoma cancers, but little is known about how they understand and manage their cancer risks.
Prostate cancer (PC) is a major health concern for men worldwide, with an estimated lifetime risk of ~14 %. A recent comprehensive analysis of mutational processes revealed ageing and mismatch repair as the only altered processes in PC.
Prostate cancer is the most commonly diagnosed cancer among men in the United States as well as most Western countries. A significant proportion of men report having a positive family history of prostate cancer in a first-degree relative (father, brother, son), which is important in that family history is one of the only established risk factors for the disease and plays a role in decision-making for prostate cancer screening.
Genomic studies of localized and metastatic prostate cancer have identified a high prevalence of clinically actionable alterations including mutations in DNA repair genes. In this manuscript, we review the current knowledge on DNA repair defects in prostate cancer and provide an overview of how these alterations can be targeted towards a personalized prostate cancer management.
