Green Tea As Chemoprevention Agent For Oral Cancer

November 5, 2009
By: Science Daily

Green tea extract has shown promise as cancer prevention agent for oral cancer in patients with a pre-malignant condition known as oral leukoplakia, according to researchers at The University of Texas M. D. Anderson Cancer Center.

The study, published online in Cancer Prevention Research, is the first to examine green tea as a chemopreventative agent in this high-risk patient population. The researchers found that more than half of the oral leukoplakia patients who took the extract had a clinical response.

Long investigated in laboratory, epidemiological and clinical settings for several cancer types, green tea is rich in polyphenols, which have been known to inhibit carcinogenesis in preclinical models. Still, clinical results have been mixed.

"While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer," said Vassiliki Papadimitrakopoulou, M.D., professor in M. D. Anderson's Department of Thoracic/Head and Neck Medical Oncology, and the study's senior author. "The extract's lack of toxicity is attractive -- in prevention trials, it's very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm."

In the Phase II dose-finding study, 41 M. D. Anderson oral leukoplakia patients were randomized between August 2002 and March 2008 to receive either green tea extract or placebo. Participants took the extract, an oral agent, for three months at one of three doses -- 500 per meter squared of body mass (mg/m2); 750 mg/m2 or 1,000 mg/m2 -- three times daily. To best assess biomarkers, participants also underwent a baseline and 12-week biopsy, an important component in the design of the study, the researchers say.

"Collecting oral tissue biopsies was essential in that it allowed us to learn that not only did the green tea extract appear to have benefit for some patients, but we pointed to anti-angiogenic effects as a potential mechanism of action," said Anne Tsao, M.D., assistant professor in the Department of Thoracic/Head and Neck Medical Oncology, and the study's first author. "While preliminary because our patient population was so small, this gives us direction for further study."

Of those taking green tea at the two highest doses, 58.8 percent had a clinical response, compared with 36.4 percent in the lowest extract dose and 18.2 percent in the placebo arm. At an extended follow-up with a mean of 27.5 months, 15 participants had developed oral cancer, with a median time to disease development of 46.4 months.

Although not statistically significant, the green tea extract also improved histology and trended towards an improvement in a number of biomarkers that may play a vital role in predicting cancer development.

Another important finding, say the researchers, was that that the extract was well tolerated. Side effects, including insomnia and nervousness, were mostly seen in the high-dose group but produced no significant toxicity.

"While these are encouraging findings, much more research must be done before we can conclude that green tea may prevent oral or any other type of cancer. It's also important to remind people that this trial enrolled very few participants who, at the highest dose levels took the equivalent of eight cups of green tea three times a day," said Papadimitrakopoulo. "We need to further understand if green tea offers longer-term prevention effects for patients."

Papadimitrakopoulo and Tsao think that future studies with green tea in this high-risk population should focus on participants being exposed to the supplement for a longer time period. The researchers also stressed that the green tea extract studied in this trial was never sold over-the-counter and/or the Internet, both of which are not highly regulated. Rather, the compound was exclusively developed as a pharmaceutical.

According to the American Cancer Society, more than 35,720 are expected to be diagnosed with oral and/or pharynx cancer and the five year survival rate is less than 50 percent.

The study was funded by Ito En, the company that produced the green tea extract.

In addition to Papadimitrakopoulou and Tsao, other M. D. Anderson authors on the study include: Waun Ki Hong, M.D., professor and chair of the Division of Cancer Medicine; Jack Martin, D.D.S., professor in the Department of Dental Oncology; Li Mao, M.D., adjunct professor and Xi Ming Tang, M.D., Ph.D. research scientist, both of the Department of Thoracic/Head and Neck Medical Oncology; Adel El-Naggar, M.D., Ph.D., professor in the Department of Pathology; Iganacio Wistuba, M.D., professor in the Department of Pathology-Research; Kirk Culotta, Phar M.D., Department of Pharmacy Pharmacology Research; Ann Gillenwater, M.D., professor in the Department of Head and Neck Surgery; J. Jack Lee, Ph.D., professor and Diane Liu, both of the Department of Biostatistics. Other authors include Yuko Sagesaka of Ito En, Ltd.


Green tea reduces risk of blood cancers by 42 percent

November 9th, 2009
By: Natural News

A Japanese green tea study has determined impressive results regarding the reduction of blood and lymph cancers. Tohoku University researchers found a 42 percent reduction for blood cancers and 48 percent reduction for lymph cancers with high green tea consumption.

In a study published in the September issue of the American Journal of Epidemiology, Dr. Toru Naganuma of Tohoku University School of Medicine in Senda and colleagues reported that drinking at least five daily cups of green tea was found to slash the risk of blood cancers by 42% and lymph system cancers by 48%. What's more, these enormous reductions in cancer were consistent in both men and women and in people with various body mass sizes.

While Dr. Naganuma was looking at blood and lymph cancer rates, another research team in the Division of Epidemiology in Tohoku University's Department of Public Health and Forensic Medicine was also searching the Ohsaki National Health Insurance Cohort Study and they discovered yet another link between green tea and cancer prevention. Their study, published in the September issue of the journal Cancer Causes and Control found that green tea consumption was inversely associated with the incidence of liver cancer. The study documented that the more green tea consumed, the more the risk plummeted -- five cups or more offered the most protection from liver malignancies.

All of the research is based on findings from the huge Ohsaki National Health Insurance Cohort Study in Japan which involved 41,761 Japanese adults between 40 and 79 years of age. None of the research subjects had a history of cancer when the study started and their diets, along with other lifestyle factors and any health problems they developed, were followed for about ten years.The epidemiological studies (statistical observations over time) of Japan have been bolstered with western clinical application and lab studies that revealed interesting observations.

For example, the Mayo Clinic of Minnesota fed leukemia patients large doses of GTE's (green tea extracts) and discovered immediate benefits in their patients. However, the doctors consider GTE's a helpful adjunct to orthodox cancer treatments. They declined the notion of using GTE's exclusively or in conjunction with other natural cancer treatments.

Researchers in Spain and England isolated the mechanics of green tea's inhibition of cancer cells. Their research was published back in the March 2005 issue of Cancer Research. They found that ECGC, an extremely abundant catechin in green teas inhibits the enzyme dihydrofolate reductase (DHFR).

Catechins are active polyphenolic antioxidant metabolites in green tea. The DHFR enzymes they inhibit are needed by cancer cells to proliferate. Upon closer scrutiny of green tea ECGC, they determined that its molecular structure closely resembles that of the cancer drug methotrexate used in chemotherapy.

The good news is that the binding properties of ECGC is not as intense as the drug methotrexate. Therefore, the side effects of green tea are minimal. But there is one situation where green tea's ECGC binding to DHFR can be detrimental: ECGC binding to DHFR can inhibit the folic acid needed by women pregnant in their first trimester. This situation has been shown to increase the risk of her child being born with spina bifida or other fetal neurological disorders.


Coffee, Green Tea Reduce Diabetes Risk: Study

November 09, 2009
By: The International News

Drinking caffeineated green tea and coffee could protect women and overweight men from type 2 (non-insulin dependent) diabetes.

Researchers from Japan analysed 17,413 men and women aged 40 to 65 years, who were free of diabetes at baseline. New cases of diabetes occurred in 231 men and 213 women over a 5-year follow up period, Health News reported.

Those who reported drinking six or more cups of green tea per day were 33 percent less likely to develop type 2 as compared to subjects who did not consume tea. Those who reported drinking three or more cups of coffee per day were 42 percent less likely to develop the condition than non-coffee drinkers. Drinking black Chinese tea did not appear to protect against type 2 diabetes.

The apparent protection was most pronounced in women and overweight men at higher risk for insulin resistance, a precursor to diabetes.

These findings from a Japanese population resemble results obtained in European and US populations in which people who drank seven or more cups of coffee per day had a 29 to 52 per cent reduced risk of diabetes as compared to those who drank fewer cups of coffee per day or none at all.


Study Shows Lemon Juice Boosts Health Benefits of Green Tea

November 4, 2009
By: Personal Liberty News Desk

According to new research, the beneficial antioxidant ingredients of green tea called catechins are better absorbed when the tea is mixed with lemon juice.

Lemon fruit abounds in ascorbic acid—which is the scientific name for vitamin C—and scientists from Purdue University showed that catechins can be absorbed up to three times as fast by intestinal cells and get into the bloodstream when the vitamin is present.

Connie Weaver, head of the National Institutes of Health Purdue University-University of Alabama at Birmingham Botanical Research Center for Age-Related Diseases, which funded the study, explains that there is much interest in studying bioactive materials that might protect people from disease and promote better health and well-being.

She adds that "what’s been totally ignored is the way these materials are found in foods in combination with other ingredients."

Catechins are a class of antioxidant polyphenols that scientists believe reduce the risk of heart disease, stroke, cancer and diabetes, and in addition to tea they can be found in cocoa and grapes.


UMC to Enroll Subjects for Green Tea-HPV Study

October 26th, 2009
By: Margaret Studer

The University Medical Center in Arizona is calling for about 156 test subjects in its study to see if green tea extract could be used to clear the human papilloma virus, the virus that can lead to cervical cancer in women. Previous experiments have shown that green tea extract helps clear up cervical lesions created by the virus. Now scientists want to see how effective it is on the virus itself.

The scientists are focusing their attention on Polyphenon E, a chemical present in green tea. This is the same green tea extract that other studies have shown may slow prostate cancer in men.

Researchers plan to enroll 156 patients with HPV or abnormal pap smears in a four-week study known as a double-blind placebo controlled experiment. Half of the women will receive the Polyphenon E and the other half with receive a placebo. Neither the researchers nor the subjects will know who is receiving which treatment until the study is over. Over the four-month period of the study, test subjects will make six study visits to track the progress of the HPV. They will be compensated $250 at the end of the study.

Since it’s know that a person’s immune system can clear up HPV on its own, the objective of the study is to see if the more women who receive the Polyphenon E clear the HPV than those receiving the placebo. Other studies in the past decade have shown that green tea is a boost to the immune system. It may prove to boost the immune system well enough to clear HPV.


Green Tea May Help Those Suffering From Stress

October 10th, 2009
By: Margaret Studer

A new study from Japan was published this week showing that green tea may help with stress. The study found that drinking green tea may reduce psychological stress by as much as 20 percent. In this study of 42,093 Japanese individuals, 6.6% suffered from psychological stress. In those individuals suffering from stress, green tea consumption improved psychological well-being.

The global tea market is worth about $941 million. Green tea makes up just 20 percent of the total tea market. However, research continues to show that it provides health benefits much greater than black tea, which makes up 78 percent of the market. Green tea contains over four times more antioxidants than black tea. For example, green tea contains 70 mg catechins per 100 mL compared to just 15 mg per mL for black tea.

So if you're a tea drinker, consider switching from black tea to green tea and take advantage of the additional antioxidants and their associated health benefits. However, keep in mind that this study looked at the traditional consumption of green tea, not the blended, frozen green tea treat commonly consumed here in the United States at popular cofee shops. The extra sugar and fat found in the frozen, blended preparation is likely to counter the benefits of green tea. To get maximum benefits consume green tea as it is traditionally prepared by the Japanese and other Asian countries.
