Cocktail of five vitamins may give cancer patients an extra two years

Cancer patients with terminal disease who take a daily cocktail of vitamins could extend their lives by two years or even longer, claim researchers.

Three out of four in a pilot study survived an average of five months longer than the expected one year, and some were still alive three years after treatment started.

Dr Bob Lister, co-author of the study by British and Danish researchers, said the results were similar to the survival gains from new drugs and in some cases better.

But the important difference was there were no side effects reported by patients taking vitamins, he said.

Dr Lister, chairman of the Institute of Brain Chemistry and Human Nutrition at London Metropolitan University, said: 'We believe these results are meaningful and justify trying to get backing for a proper clinical trial.

'People with cancer are constantly asking what can we do, not necessarily to beat the cancer but to have a better quality of life whatever the length of survival.

'Most importantly, taking these supplements is extremely safe, and there were no adverse reactions among the patients.'

The study followed patients suffering from breast, lung, brain, colon and other forms of cancer in Denmark between 1990 and 1999 who continued taking conventional cancer medication.

During the nine-year period, the patients were treated with coenzyme Q10 - a vitamin-like compound-essential for producing energy made naturally in the body - and six other antioxidants including vitamins A, C and E, selenium, folic acid, and beta carotene (which was not given to lung cancer patients for safety reasons).

The patients were predicted to live for an average of 12 months, but 76 per cent lived an average of five months longer.

The doses of the supplements, supplied by manufacturers Pharma Nord, were large but were within recommended safety limits, said Dr Lister.

In addition, patients received small amounts of other nutrients including fish oil and B vitamins.

The findings are published in the Journal of International Medical Research.

However Dr Joanna Owens of Cancer Research UK said: 'This very small study tells us nothing new about supplements and cancer.

'All the patients in this study took the supplements so it is impossible to judge if they had any effect.

'It is no surprise that in a group of people with different types of cancer, some survived for longer than might have been expected, while others sadly did not.

'As yet, there is not enough evidence to know whether supplements are helpful or harmful during cancer treatment.

'We know that high doses of some supplements can increase the risk of cancer and it's possible that high doses of antioxidants can make treatment less effective.

'Until we know for sure, our advice is to try to get the vitamins you need through a balanced and varied diet rather than through vitamin supplements.'
