Abstract

Experimental and human epidemiologic data suggest a protective rolefor vitamin D in large bowel cancer. To investigate this association, weconducted a nested case-control study within a Finnish clinical trial cohort.Cases (n = 146) were participants diagnosed with primary adenocarcinoma ofthe large bowel. Controls were matched (2:1) to cases on age, date ofbaseline blood draw, and study clinic. Prediagnostic serum levels of thevitamin D metabolites, 25-hydroxyvitamin D (25-OH D), and1,25-dihydroxyvitamin D (1,25-DIOHD) were used as primary exposure measures.The baseline geometric-mean serum level of 25-OH D was 11.6 percent lower incases than in controls (12.2 cf 13.8 ug/l, P = 0.01) while serum levels of1,25-DIOH D did not differ by case-control status. No association was seenbetween serum levels of 1,25-DIOH D and large bowel cancer risk. However, theestimated relative risk (RR) of large bowel cancer decreased with increasinglevel of serum 25-OH D and the associa tion was more pronounced for rectalcancer (55 cases; RR by quartile = 1.00, 0.93, 0.77, 0.37; trend P = 0.06).Neither exclusion of early cases nor multivariate adjustment for potentialconfounders materially altered these estimates. There was no evidence ofeffect modification by level of 1,25-dihydroxyvitamin D or with other knownrisk-factors for large bowel cancer.
