Green Tea And COX-2 Inhibitors Combine To Slow Growth Of Prostate Cancer

Drinking a nice warm cup of green tea has long been touted for its healthful benefits, both real and anecdotal. But now researchers have found that a component of green tea, combined with low doses of a COX-2 inhibitor, could slow the spread of human prostate cancer.

In the March 1 issue of Clinical Cancer Research, researchers from University of Wisconsin-Madison demonstrate that low doses of the COX-2 inhibitor celecoxib, administered with a green tea polyphenol called pigallocatechin-3-gallate (EGCG), can slow the growth of human prostate cancer. Their experiments were performed in cell cultures and in a mouse model for the disease.

"Celecoxib and green tea have a synergistic effect -- each triggering cellular pathways that, combined, are more powerful than either agent alone," said Hasan Mukhtar, Ph.D., professor of dermatology at the University of Wisconsin and member of Wisconsin's Paul Carbone Comprehensive Cancer Center. "We hope that a clinical trial could lead to a preventative treatment as simple as tea time."
