Sponsor: Medical University of South Carolina
Conditions: Prostate Cancer, Vitamin D Deficiency, Stress Reaction
Interventions: cholecalciferol, Standard of Care Prostate Biopsy - collection of 13th core for RNA-seq, Standard of Care Prostate Biopsies at baseline and after one year vitamin D3 supplementation, Allostatic Load
Countries: United States
Veterans between the ages of 50-75, who are having a prostate biopsy, will be recruited for their permission to collect an extra biopsy core for RNA-sequencing. If the participants' treatment decision is Active Surveillance, they will be enrolled into the intervention phase of the study. They will receive supplementation with Vitamin D3 (4,000 IU) daily with repeat (surveillance) prostate biopsy one year later. At that time an extra prostate sample core will be collected for RNA-sequencing to determine changes over time. Measurements for allostatic load (body stress/inflammatory markers) will also be collected at the time of enrollment and at the repeat prostate biopsy visit.
Sex: MALE
Age: 50 Years to 75 Years
