Background: Prostate cancer is the most common cancer and the second leading cause of death in males in the United States with an estimated 191,930 new cases and 33,330 deaths in 2020. There has been progress in identifying established risk factors for the development of prostate cancer, including genetic predisposition. The study of the molecular genetics of prostate cancer has identified pathogenic variants, such as BRCA1 and BRCA2 (associated with hereditary breast and ovarian cancer syndrome), HOXB13 (associated with hereditary prostate cancer), and DNA mismatch repair (MMR) gene variants (MLH1, MSH2, MSH6, PMS2, and EPCAM) associated with Lynch syndrome. While our understanding of molecular genetics continues to grow, there remains a need to identify additional germline and somatic mutations and alterations that may increase an individual s risk to develop prostate cancer and potentially the aggressiveness of the disease. In studying the following alterations in prostate cancer, in both localized and advanced stages, potential expanded molecular findings may lead to actionable therapeutic targets and biomarker development. A better understanding of molecular genetics in a longitudinal study of subjects with prostate cancer may be helpful for the design of future treatment studies, and to develop a better understanding of the natural history of the disease Objectives: To longitudinally evaluate subjects with prostate cancer with known germline and/or somatic variants in PIK3 and/or AKT, PALB2, BRIP1, RAD50, RAD51, RAD54, RB1, SPOP, Wnt/B-catenin pathway, and MMR genes: MLH1, MSH2, MSH6, PMS2, and EPCAM to better understand the natural history of the disease. To longitudinally evaluate subjects with tumor mutational burden-high (TMB-H) prostate cancer [greater than or equal to 10 mutations/megabase (mut/Mb)]. Eligibility: Subjects with histologically confirmed prostate cancer Must have known germline and/or somatic variants in PIK3 and/or AKT, PALB2, BRIP1, RAD50, RAD51, RAD54, RB1, SPOP, Wnt/B-catenin pathway, and MMR genes: MLH1, MSH2, MSH6, PMS2, and EPCAM and/or TMB-high or be deemed an exceptional responder. NOTE: any platform for genomics testing is acceptable (research or CLIA-certified) Age greater than or equal to 18 years old Design: This will be a long-term multi-center study to comprehensively study participants with prostate cancer. Participants will provide clinical information (including medical history, clinical tests, imaging studies and reports, surgical pathology reports, genetic test results). Since long-term follow-up of individuals with prostate cancer is a major feature of the study, local sites intend to maintain active contact with study subjects for as long as possible. Participants will be followed throughout the course of their illnesses, with particular attention to patterns of disease recurrence and progression, response to therapies and duration of responses.
