- PSA ≤ 10.0 ng/mL
- PSA \< 15 ng/mL in patients with benign prostatic hyperplasia or prostatitis allowed
- PSA doubling time ≥ 3 months
- PATIENT CHARACTERISTICS:
- Life expectancy ≥ 3 months
- ECOG performance status 0-2
- No history of allergic reactions attributed to tomatoes, fish, soybean oil, gelatin capsules, or compounds of similar chemical or biologic composition to lycopene (carotenoids) or fish oil (omega-3 fatty acids)
- No uncontrolled intercurrent illness including, but not limited to, the following:
- Ongoing or active infection
- Symptomatic congestive heart failure
- Unstable angina pectoris
- Cardiac arrhythmia
- Psychiatric illness or social situations that would limit study compliance
- PRIOR CONCURRENT THERAPY:

- More than 4 weeks since prior and no concurrent lycopene, fish oil (omega-3 fatty acids), or any other preparation intended to supplement levels of omega-3 unsaturated fatty acids
- More than 4 weeks since prior and no concurrent finasteride, dutasteride, saw palmetto or any other herbal/nutritional preparation indicated to affect hormone levels
- More than 1 month since prior nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase-2 (COX-2) inhibitors, and/or aspirin for \> 7 days duration
