5 Clinical Trials for Various Conditions
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.
This research study is designed to determine if targeted Magnetic Resonance Imaging (MRI) Ultrasound (US) fusion biopsy is better than the standard of care ultrasound guided biopsy alone in diagnosing subjects with clinically significant prostate cancer with MRI visible lesions. This study will consist of comparing the standard of care (ultrasound guided prostate biopsy) with the protocol biopsy which consists of an ultrasound guided prostate biopsy and a MRI/US fusion tracked prostate biopsy.
This study will determine if targeted (Magnetic Resonance (MR) / Ultrasound (US) fusion biopsy) plus conventional biopsy is superior to conventional biopsy alone in diagnosing subjects with prostate cancer.
This study aims to define the natural history of men at high genetic risk for prostate cancer on the basis of specific germline genetic mutations, family history, or Black/African ancestry and evaluate the utility of prostate MRI as a screening tool. The hypothesis is that this targeted population of men are at elevated risk of developing prostate cancer compared to the general population, and enhanced screening with MRI will enable early detection and diagnosis of potentially aggressive prostate cancer, characterization of the penetrance of specific mutations, and potentially identify new genetic risk mutations.
Prostate cancer is the most common non-skin cancer among Veterans and the second leading cause of male cancer death. Current methods of screening men for prostate cancer are inaccurate and cannot identify which men do not have prostate cancer or have low-grade cases that will not cause harm and which men have significant prostate cancer needing treatment. False-positive screening tests can result in unnecessary prostate biopsies for men who do not need them. However, new genetic testing might help identify which men are at highest risk for prostate cancer. This study will examine whether a genetic test helps identify men at risk for significant prostate cancer while helping men who are at low risk for prostate cancer avoid unnecessary biopsies. If this genetic test proves beneficial, it will improve the way that healthcare providers screen male Veterans for prostate cancer.
