High carbohydrate intake may increase cancer recurrence risk

IANS  |  New York 

Consuming high amounts of carbohydrates and sugar prior to treatment for head and neck may increase the patients' risks of recurrence and mortality, a new study reports.

Patients who consumed the most total carbohydrates and sugars -- in the form of sucrose, fructose, lactose and maltose -- in the year preceding the treatment were at greater risk of mortality from any cause during the follow-up period.

Out of the 400 cancer patients in the study, published in of Cancer, more than 17 per cent experienced recurrence of their cancer, and 42 patients died from it.

Associations among carbohydrate intake and patient outcomes differed by cancer type and stage, said Anna E. Arthur, at the at Urbana-Champaign.

However, eating moderate amounts of fats and starchy foods such as whole grains, potatoes and legumes after treatment could have protective benefits, reducing the patients' risks of recurrence and death, he added.

"Our results, along with the findings of other studies, suggest that diet composition can affect cancer outcomes," said Amy M. Goss, at the University of

Higher mortality rates were found among people with who consumed the greatest amounts of total carbohydrates, total sugars and simple carbohydrates, but the researchers found no such associations among people who had oropharyngeal

"Although in this study we found that higher total carbohydrate and total sugar were associated with higher mortality in patients, because of the study design we can't say that there's a definitive cause-effect relationship," Arthur said.

Five-year survival rates among these patients continue to be low, in part because these are often detected in the later stages, putting patients at high risk of recurrence, the researchers said.
