T-reg Function Changes: a Novel Immune Regulatory Effect Underlying Benefit of Statin Use on Lethal Prostate Cancer
This study will evaluate whether simvastatin reduces intraprostatic immunosuppressive microenvironment through YAP-mediated T-reg dysfunction, and increases intraprostatic anti-tumor immune response in men recently diagnosed with localized prostate cancer electing to receive prostatectomy for their care. Half the men will be randomized to receive statins for 8 weeks prior to their surgery, while the other half will receive standard of care.
• Men with pathologically-confirmed localized prostate cancer determined to be intermediate (stage T2b, or Gleason 7, or PSA 10-20 ng/mL) or high risk (stage T2c, or PSA \>/=20 ng/mL, or Gleason \>/=8) of biochemical recurrence at the time of biopsy
• Electing to undergo prostatectomy;
• Ability to provide written informed consent and willing to complete study procedures.
