简要总结
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.
详细描述
Background:
- Prostate cancer (PCa) is the most common non-dermatologic malignancy among American men and is a leading cause of cancer mortality. Men of African Ancestry (AA) have a 1.8- fold higher incidence of prostate cancer and a 2.2-fold higher likelihood of death when compared to men of European Ancestry. The predominant factor in the increased death rate is the increased incidence of cancer. The underlying reasons for the increase in incidence are controversial but likely include genetic and environmental factors.
- One strategy to counteract the effects of increased cancer incidence in a given patient population is to utilize earlier and/or more intense screening as it leads to earlier diagnosis and potentially better outcomes.
- Multiparametric MRI (mpMRI) is a proven useful tool in the diagnosis of prostate cancer but access to high quality mpMRI in communities of color is often limited.
- For individuals who are members of communities of color, high quality prostate MRI is a limited resource and insurance coverage is often denied. Given the high risk of prostate cancer in these communities, the benefits of screening with mpMRI and mpMRI guided biopsies could be significant as it could enable earlier diagnosis.
Objective:
-To compare results of mpMRI and mpMRI guided biopsy in diagnosing clinically significant prostate cancer between men of African Ancestry from hospitals providing medical care for communities of color (e.g., Howard University Hospital, Washington Hospital Center) with the population of self-referred participants seen at NIH who are mostly of European Ancestry.
