High carbohydrate diet linked to increased risk of colon cancer recurrence

Lifestyle choices have been reported to be a significant factor in the development of colorectal cancer. According to a new study, a high carbohydrate diet increases the risk of colon cancer recurrence. Jeffrey Meyerhardt, MD, MPH, from the Dana-Farber Cancer Institute in Boston, Massachusetts and colleagues published their findings online on November 7 in the Journal of the National Cancer Institute

The researchers note that they ha have identified a link between higher dietary glycemic load and total carbohydrate intake and increased risk of cancer recurrences or death among stage 3 colon cancer patients. They note that this finding suggests that diet and lifestyle modification can have a role in improving patient survival. The authors point out that lifestyle choices such as obesity and inadequate exercise have been shown to directly influence insulin levels and recent studies have reported a direct link between factors that lead to hyperinsulinemia, cancer recurrence, and mortality in colorectal cancer survivors. However, the influence of glycemic load and other related dietary intakes have on the survival of colon cancer patients is unknown. The researchers designed a study that assessed the effects of glycemic load and total carbohydrate intake on the survival of stage 3 colon cancer patients. They conducted an observational study comprised of 1,011 stage 3 colon cancer patients who reported their dietary intake both during and six months after participating in an adjuvant chemotherapy trial. The researchers assessed the influence of glycemic load, glycemic index, fructose, and carbohydrate intakes on both mortality and cancer recurrence.
