Filter by:Background: Prostate cancer (PCa) is one of the most common cancers in American men; it is a leading cause of death. Men of African ancestry have a higher rate of prostate cancer, and a higher likelihood of death, compared to men of European ancestry. The reasons for these higher rates are not known; they may include genetic and environmental factors. Better screening methods are needed. Objective: To test an imaging technology called multiparametric magnetic resonance imaging (mpMRI) for detecting prostate cancer in men of African ancestry. Eligibility: Men of African ancestry aged 35 years or older with prostate cancer and/or a strong family history of prostate cancer. Design: Participants will be screened. They will have a physical exam with blood and urine tests. Participants will have an mpMRI. They will lie on a narrow bed that slides into a large cylinder. They will lie still for about 45 minutes. They will hear loud noises during the scan; they may wear earplugs or headphones to muffle the sound. Some participants may have a dye injected into a vein. If the scan indicates participants risk of prostate cancer is medium or high, they will have a biopsy: The area will be numbed, and samples of tissue will be removed from the prostate. The biopsy will be done within 6 months. If the scan indicates participants risk of prostate cancer is low, they will not have a biopsy. All participants will be followed for 5 years. They and/or their local doctors will be contacted once a year for follow-up. Additional mpMRIs may be recommended. ...
