Green Tea Catechins and Prevention of Prostate Cancer in High Risk Men

In going through old papers today, I've excavated a study looking at green tea and men in a high risk group of developing prostate cancer because they've been diagnosed with high-grade prostate intraepithelial neoplasia (high grade PIN). High grade PIN means that cells in the prostate gland are changing abnormally in a way that can develop into prostate cancer. It is diagnosed with a biopsy. 

Today's study is an Italian research study published in Cancer Research from January 15, 2006 by Bettuzzi, et al. The title of this paper is "Chemoprevention of Human Prostate Cancer by Oral Administration of Green Tea Catechins in Volunteers with High-Grade Prostate Intraepithelial Neoplasia: A Preliminary Report from a One-Year Proof-of-Principle Study."

Typically, men diagnosed with high grade PIN undergo "active surveillance" also known as "watch-and-wait". They get biopsies every 3-6 months and wait until they find out if it progresses to cancer or not. As you can imagine, many people want to do something about it and not just wait for the disease to possibly progress.

This study cites previous sources that found 30% of men with high grade PIN develop prostate cancer within one year after repeated biopsy. This study looked at 60 volunteers diagnosed with high-grade PIN. In this study, 30% of the volunteers taking the placebo developed prostate cancer in one year, but volunteers taking 600 mg of green tea/day standardized to 75.7% catechins (51.8% of which was EGCG) only had a 3% incidence of developing  prostate cancer in 1 year in this study. Wow--a 30% to 3% chance in one year of developing prostate cancer with taking standardized green tea extract! Additionally, volunteers taking the green tea extract found a decrease in lower urinary tract symptoms.  All this being said, this is a preliminary report with a fairly small sample size, but it is promising for those faced with watching and waiting.

If you have been diagnosed with a premalignant lesion, such as high-grade PIN, I do offer a program at my Tulsa office called "Take Action Now" to help stack the cards in your favor. I can't promise that you will never be diagnosed with cancer, but we can use the latest evidence and research in natural medicine to give you a better chance of cancer prevention.
