Brief Summary:
This randomized pilot clinical trial compares tangerine and red tomato juice in treating patients with prostate cancer undergoing surgery. A diet high in lycopene, a substance found in tomatoes, may help prevent normal cells from transforming into cancer cells in patients with prostate cancer.

Detailed Description:

PRIMARY OBJECTIVES:

I. To conduct a randomized, three-arm pilot clinical trial to determine compliance and safety of daily consumption of tangerine tomato juice or red tomato juice.

SECONDARY OBJECTIVES:

I. To quantify total carotenoids, total lycopene (LYC), cis-LYC, trans-LYC, phytoene, phytofluene, and lycopene metabolites in plasma and prostate tissue in the three groups of men.

II. To evaluate serum biomarkers related to prostate carcinogenesis, including those previously impacted by tomato phytochemicals (testosterone, sex hormone-binding protein [SHBP], insulin-like growth factor [IGF]-I, IGF-binding protein [BP]3, vascular endothelial growth factor [VEGF], and a panel of anti-inflammatory cytokines) by validated assays.

III. To evaluate molecular signatures using the 200 gene quantitative Nano-string nCounter code set (selected genes known to be impacted by dietary components, genes impacted by common prostate genetic and epigenetic damage, and those regulated by testosterone) and micro-ribonucleic acid (RNA) nCounter code set.

IV. To plot the distribution of carotenoid metabolites across the matrix versus the epithelium and cancer versus non-cancer areas of the prostate using matrix-assisted laser desorption ionization (MALDI) imaging of a limited number of samples.

OUTLINE: Patients are randomized to 1 of 3 treatment groups.

GROUP I: Patients consume no tomato juice.

GROUP II: Patients consume two cans of tangerine tomato juice daily until their scheduled surgery (approximately 4 weeks).

GROUP III: Patients consume two cans of red tomato juice daily until their scheduled surgery (approximately 4 weeks).

Arm Intervention/treatment
No Intervention: Group I (control, no juice)
Patients consume no tomato juice.
Experimental: Group II (tangerine tomato juice)
Patients will consume two 5.5 oz. cans of tangerine tomato juice every day until their scheduled surgery. (approximately 4 weeks)
Dietary Supplement: dietary intervention (tangerine tomato juice)
Group II will consume two 5.5 oz. cans of tangerine tomato juice every day until their scheduled surgery. (approximately 4 weeks).
Other Names:
  • Dietary Modification
  • intervention, dietary

Other: questionnaire administration
Men enrolled in the study will be asked to complete a 3-Day Food Record and a series of additional questionnaires (urologic symptom and quality of life questionnaire) at home.
Other Name: Ancillary studiesAll

Other: Correlative studies
Blood and urine samples at enrollment and blood, urine, and prostate tissue at the time of surgery to determine compliance with the intervention product and tomato phytochemical biodistribution. Additionally, we will correlate each type of tomato juice with lycopene presence in plasma, urine, and tissue provided by subjects on the day of surgery.
Other Name: laboratory biomarker analysis

Experimental: Group III (red tomato juice)
Patients consume two cans of red tomato juice daily until their scheduled surgery (approximately 4 weeks).
Dietary Supplement: dietary intervention (red tomato juice)

Primary Outcome Measures :
  1. Incidence of toxicity [ Time Frame: Up to time of surgery ]
  2. Compliance of daily consumption of tangerine tomato juice or red tomato juice [ Time Frame: Up to time of surgery ]
  3. Differences in carotenoid levels of biological samples between groups [ Time Frame: Up to time of surgery ]
    Linear regression analysis will be used to examine differences in carotenoid levels of biological samples between groups.


Secondary Outcome Measures :
  1. Change in histopathologic markers between the treatment groups [ Time Frame: Baseline to time of surgery ]
    Compared via 3 way analysis of variance (ANOVA) with pairwise comparisons or nonparametric Kruskal-Wallis tests where appropriate.

  2. Change in immunohistochemical markers between the treatment groups [ Time Frame: Baseline to time of surgery ]
    Compared via 3 way ANOVA with pairwise comparisons, or nonparametric Kruskal-Wallis tests where appropriate.
