Objective: Several observational and epidemiological studies have suggested that the incidence of prostate cancer seems to be lower in relation to ultraviolet light exposure and distance from the equator, which has led to theories that vitamin D may play a role in the prevention of cancer. This study seeks to determine if a correlation exists between vitamin D levels in the serum as measured by 25-hydroxyvitamin D and serum PSA in male veterans with prostate cancer.
Methods: Veterans with prostate cancer seen in the urology or oncology clinic at the Southeast Louisiana Veterans Affairs Healthcare system were identified using ICD 9 codes. After informed consent, serum 25-hydroxyvitamin D levels and PSA were drawn. 119 patients were enrolled on the study from 1/16/13 to 11/15/13. Demographic data such as age, ethnicity, cancer stage, use of vi.. View More»
