  Purpose
The purpose of this research study is to compare the effects of a lycopene supplement made from tomatoes to a placebo (a capsule with no active ingredients) in men who have abnormal cells in the prostate, but have not yet had cancer detected. This study will allow us to see if taking lycopene for six months leads to favorable changes in abnormal prostate tissue and in chemicals measured in the blood that go along with a higher risk of developing cancer.

Primary Outcome Measures:
  • Tissue Biomarkers [ Time Frame: baseline and 6 months ]
    We will use conventional immunohistochemistry and computer-based image analysis to test the hypothesis that the lycopene supplements alter the expression of proteins marking the status of proliferation, differentiation, cell regulation and apoptosis in high-risk tissue.

  • Changes in Serum Biomarkers [ Time Frame: baseline and 6 months ]
    Change in serum lycopene, umol/L


Secondary Outcome Measures:
  • Changes in Nuclear Morphometry [ Time Frame: baseline and 6 months ]
    We will use a computerized image analysis system designed for the chemoprevention setting to test the hypothesis that the antioxidants cause a favorable change in a nuclear morphometry index based on nuclear size, shape and chromatin texture.
