Bilberry extract -- can it help prevent certain cancers?
Date:10/4/2007

ducts. Our research project is looking at substances which can be taken as tablets and which may slow down the development of a cancer, or even prevent it from occurring in the first place.

"In the future, these agents could be used as drugs to stop cancers from developing in apparently healthy people, or they could be used to prevent it recurring in patients who have had successful treatment of cancer. The ideal type of drug to use for this would be one with very few, or no, side effects, which could be taken daily for many years with no problems."

The Mirtoselect project is the latest in a long line of research carried out by Professor Gescher and Professor Will Steward, working with surgical colleagues at the Leicester General Hospital.

Professor Gescher commented: "We are interested in agents, many of them derived from diet, which may prevent cancer or delay its onset. For quite a number of years we have been working on curcumin, the yellow constituent of curry.

"Our current research, funded by Hope Against Cancer, involves berries, coloured blue or red, which contain chemicals called anthocyanins. These have long been suspected to have a beneficial effect in this sense.

"We take an individual chemical out of its context and investigate it. Instead of asking people to eat a punnet of bilberries, we ask them to take Mirtoselect, which contains anthocyanins. We also study whether anthocyanins are more efficacious when they are part of a dietary mixture. There is some evidence to say that this may be the case."

Developing a new drug, even one derived solely from fruit or some other food substance, is time-consuming, and Ms Thomasset is still recruiting colorectal and liver cancer patients to help with the study.

In the meantime, one of her principal tasks is to take body fluids such as urine and plasma from participating patients and check how much of the bilberry extract is present.
