Abstract [en]

Background and objectives: Few studies have investigatedthe association between whole-grain intake and colorectal cancer.Whole-grain products are one of the dietary items proneto measurement errors, making the use of objective measures,such as biomarkers, highly relevant. The objective of the studywas to investigate the association between biomarkers ofwhole-grain intake, alkylresorcinols, and colorectal cancer ina nested case-control study within the European ProspectiveInvestigation into Cancer and Nutrition (EPIC). Methods: We included 1372 first incident colorectal cancercases and 1372 individually matched controls and calculatedthe incidence rate ratios (IRR) for overall and sub-sites of colorectalcancer using conditional logistic regression adjusted forpotential confounders.Results: Plasma total alkylresorcinol concentrations werenot associated with risk of overall colorectal cancer, proximalcolon cancer or rectal cancer. However, high plasma total alkylresorcinolconcentrations were statistically significantly associatedwith lower incidence of cancer located in the distal (leftor descending) part of the colon. Adjusted IRR of distal coloncancer for highest versus lowest quartile of plasma alkylresorcinolwas 0.48 (95% confidence interval = 0.28 to 0.83). Furthermore,we observed an inverse association with colon cancerfor the Scandinavian part of the participants. Alkylresorcinolsmay be more appropriate as biomarkers in Middle Europe andScandinavia i.e. in areas where whole grains are regularly consumed.Conclusions: Whole-grain intake, assessed by alkylresorcinols,was associated with a lower incidence of distal coloncancer. Alkylresorcinols seem useful as objective biomarkersof whole-grain intake in populations where whole-grains are astaple part of the diet.
