Biological and Environmental modifiers of Vitamin D3 and Prostate Cancer Risk

Project: Research project

Project Details


Disparities in prostate cancer (Pca) are caused by complex interactions of genetic susceptibility, individual risk factors, and environmental factors. Pca is the second leading cause of death among all men; however African American (AA) men have the highest mortality rate of Pca of any racial/ethnic group in the U.S. This difference in mortality accounts for 44% of the overall cancer mortality disparity between AA and European-American (EA) men. Thus, there is a critical need to explore the etiologic pathways that contribute to this disparity. Unfortunately, the only well-established risk factors (age, race and family history) for Pca are non-modifiable. However recent studies have found low levels of vitamin D have been associated with increased Pca risk, and treatment with vitamin D has reduced Pca disease progression in multiple studies. These studies support the hypothesis that vitamin D deficiency increases the risk of Pca and that vitamin D is a potential chemopreventive and therapeutic agent.
