Outcome Measures

Primary Outcomes (1)

  • Measure carotenoids, including lycopene and its isomers, in blood (umol/L) and prostate tissue (nmol/g) of men after three weeks of consuming V8 vegetable juice, condensed tomato soup or tomato sauce.

    Day 0 and End of Study (an average of 23 days)

Secondary Outcomes (2)

  • Measure histobiomarkers in the prostate related to aggressive disease including Gleason Grade (number 1 - 10), tumor volume (weight) , and vascular endothelial growth factor expression (ng/mL)

    Day 0 and End of Study (an average of 23 days)

  • Measure biomarkers related to prostate cancer in controls and men consuming tomato food products prior to surgery. These biomarkers include plasma insulin like growth factor (ng/mL) and plasma prostate specific antigen (ng/mL)

    Day 0 and End of study (an average of 23 days)

Study Arms (4)

Arm I: Control

NO INTERVENTION

Men in this group consumed a tomato free diet for the duration of the study (less than or equal to 5 mg lycopene/day) and, thus, did not consume a tomato intervention product.

Arm II: Juice

EXPERIMENTAL

Commercially-available tomato food product: men in this group consumed V8® juice (11-16.5 fl. oz./day).

Other: Commercially-available tomato food product

Arm III: Soup

EXPERIMENTAL

Commercially-available tomato food product: men in this group consumed Campbell's® Tomato Soup (2-2 ¾ cups/day).

Other: Commercially-available tomato food product

Arm IV: Sauce

EXPERIMENTAL

Commercially-available tomato food product: men in this group consumed Prego® spaghetti sauce (5-7 oz./day).

Other: Commercially-available tomato food product

Interventions

Each of the three tomato food products (juice, soup, sauce) provided 25-35 mg lycopene/day.

Arm II: JuiceArm III: SoupArm IV: Sauce
