RNA-seq analysis will be used to (a) identify changes in transcriptional profiles and biological pathways in the prostate between African American and Caucasian men and (b) compare Allostatic Load results to determine stress response and (c) identify changes in the molecular signature in relation to vitamin D levels

Standard of Care Prostate Biopsy - collection of 13th core for RNA-seq

Pathology results of the prostate biopsies will be analyzed for changes in the (a) Gleason Score (b) the number of positive cores (0 to 12) and (c) the highest percentage of positive core involvement (0 to 100%).

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.

This is an open-label pilot study. The goal is to investigate the transcription and biological pathways in prostate cancer that are especially relevant to prostate cancer disparities between African American and Caucasian men. Also, to determine any significant differences in the molecular signature that exist in African American and Caucasian men in relation to their Vitamin D levels.

Recruitment will be at the Urology Clinic at the Ralph H. Johnson VA Medical Center in Charleston, SC. Men who are scheduled for a Standard of Care prostate biopsy will be consented for their permission to collect an extra prostate tissue core for RNA-sequencing.

After the pathology report is discussed by their Urologist, and the treatment decision is Active Surveillance, the participant is enrolled into the Intervention Phase. At that time, baseline allostatic load measurements (Blood pressure, pulse, waist/hip ratio, height, and weight for BMI) and bloodwork: (lipid panel, HgbA1c, albumin and creatinine, IL-6, CRP, and DHEA-s (inflammatory markers) plus a Vitamin D level, will be collected. Vitamin D3 soft gels (4,000 IU) daily (six months' supply) will be dispensed. A Social Determinants survey will also be dispensed for subject completion.

At the Urology Standard of Care six-month follow-up appointment, the vitamin D serum level will be collected and the next six months' supply of vitamin D3 will be dispensed.

At the Urology Standard of Care follow-up (repeat at 1 year) surveillance prostate biopsy, an extra prostate tissue core will be collected for RNA-sequencing. The allostatic load measurements and bloodwork will also be obtained.

Individuals having a prostate biopsy are eligible for recruitment.

RNA-sequencing analysis will be utilized to identify changes in transcriptional profiles and biological pathways in the prostate between African American and Caucasian men.

The first reported finding in the pathology report is the Gleason Score. When the prostate sample is examined under the microscope, the Pathologist determines which type of cell is the most common and which type is the second most common. Each of these cell types is given a score from 1 to 5. Higher numbers mean more abnormal, aggressive cancer cells. Because the two most common types of cancer cells are identified, the Gleason Score is a combination of these two cell types. For example, the first most common cell type is a 3 and the second is reported as a 4, then the Gleason Score is 3+4, or 7.

Changes to the baseline and repeat prostate biopsy Gleason Score will be analyzed.

During a routine prostate biopsy, 12 core samples are collected: 2 samples from the top right, front and back, 2 from the top left, front and back; 2 from the middle right and 2 from the middle left; 2 from the bottom right and 2 from the bottom left. When the 12 cores are examined under the microscope, the Pathologist identifies which cores contain cancer cells (or are positive for cancer).

Therefore, the pathology report will identify the number of positive cores between 0 to 12.

Changes to the baseline and repeat prostate biopsy positive core will be analyzed.

When the Pathologist examines the 12 core samples from the prostate biopsy, the percentage of cancer cells that are in each core is also identified. This can be from 0 to 100 percent involvement.

To facilitate the evaluation of the 12 percentages reported for the 12 cores in the pathology report, the Urology standard is to prioritize and assess the highest percentage of core involvement.

Changes to the baseline and repeat biopsy highest percentage core involvement will be analyzed.
