Fargo, N.D. — Erxi Wu, assistant professor of pharmaceutical sciences at NDSU, and Fengfei Wang, research associate of pharmaceutical sciences, co-wrote the article, "Anti-cancer activities of tea epigallocatechin-3-gallate in breast cancer patients under radiotherapy,” which will be published by Current Molecular Medicine.

In the study, they tested the hypothesis that administration of epigallocatechin-3-gallate, a polyphenol present in abundance in widely consumed tea, inhibits cell proliferation, invasion and angiogenesis in breast cancer patients. Epigallocatechin-3-gallate in 400 mg capsules was orally administered three times daily to breast cancer patients undergoing treatment by radiotherapy. Parameters related to cell proliferation, invasion and angiogenesis were analyzed while blood samples were collected at different time points to determine efficacy of the treatment.

Compared to patients who received radiotherapy alone, those given radiotherapy plus epigallocatechin-3-gallate for an extended time period (two to eight weeks) showed significantly lower serum levels of vascular endothelial growth factor, hepatocyte growth factor and reduced activation of metalloproteinase-9 and metalloproteinase-2.

“This is the first study to use EGCG in human breast cancer patients. Our results provide hitherto unreported evidence that EGCG potentiated efficacy of radiotherapy in breast cancer patients, and raise the possibility that this tea polyphenol has potential to be a therapeutic adjuvant against human metastatic breast cancer,” Wu said. They collaborated with Guoying Zhang’s lab from Yantai University, China.
