This is still early stage news, so don’t get too excited. For example, the study itself had some slight flaws.

“Unfortunately, this trial was not a randomized trial, which would have been needed to be more sure that the observed changes were truly attributable to the green tea components and not to some other lifestyle change (better diet, taking vitamins, etc.) men undertook in preparation for surgery,” added Nelson, who is also a senior editor for Cancer Prevention Research. However, “this trial is provocative enough to consider a more substantial randomized trial.”

The men chosen for the study did not sit around drinking tea all day. They received measured doses of one particular compound found in green tea.

The study included 26 men, aged 41 to 72 years, diagnosed with prostate cancer and scheduled for radical prostatectomy. Patients consumed four capsules containing Polyphenon E until the day before surgery — four capsules are equivalent to about 12 cups of normally brewed concentrated green tea, according to Cardelli.

The exciting part is the actual results which were obtained.

Findings showed a significant reduction in serum levels of HGF, VEGF and PSA after treatment, with some patients demonstrating reductions in levels of greater than 30 percent, according to the researchers.

There is still much work to be done, and this seems like a good step in the right direction.
