Trial Information

Low-Fat Diet and Omega-Fatty Acids for Prostate Cancer Prevention

Experiments have shown that a low fat diet high in fish oil may prevent the progression of
prostate cancer. The purpose of this study is to determine if a low-fat diet combined with
fish oil capsules will change the chemical substances present in blood and prostate tissue
that are related to the growth of cancer cells. This study will compare how these substances
are affected by either, a typical high-fat Western diet, or a low-fat diet combined with
fish oil.

- Has been diagnosed with adenocarcinoma (cancer)

- Has elected to undergo radical prostatectomy.

- Agrees to stop taking dietary or vitamin supplements (Lycopene, Vitamin E, selenium,
genistein) or herbal supplements (eg. saw palmetto, PC-SPES) for 1 week prior to
starting the study.

- Can safely stop taking aspirin, COX-2 inhibitors, and other anti-inflammatory
medications for 1 week prior to starting the study.

- Can safely stop taking fish oil capsules 2-weeks prior to starting the diet

Exclusion Criteria:

- Is taking LHRH agonists, androgen receptor blocking agents or finasteride.
