Abstract

Background and aimsThe association of celiac disease with colorectal neoplasia is controversial. The aim of this study was to determine the risk of colorectal neoplasia among patients with celiac disease.

MethodsWe carried out a multicenter, retrospective case–control study, within four community hospitals. Celiac disease patients with a complete colonoscopy were regarded as cases and those without celiac disease as controls. For each case, two controls matched for age, sex, indication for colonoscopy and colorectal cancer family history, were randomly selected. The main outcome evaluated was risk of colorectal polyps, adenomas, advanced neoplastic lesions and cancer.

ResultsWe identified 118 patients with celiac disease and 236 controls. The risk of polyps, adenomas and advanced neoplastic lesions was similar in both groups (OR 1.25, CI 0.71–2.18, p = 0.40; OR 1.39, CI 0.73–2.63, p = 0.31; and OR 1.00, CI 0.26–3.72, p = 1.00, respectively). On multivariate analysis, age > 75 years old, and first-grade CRC family history were associated with adenomas (OR 2.68 CI 1.03–6.98, OR 6.68 CI 1.03–47.98 respectively) and advanced neoplastic lesions (OR 15.03, CI 2.88–78.3; OR 6.46 CI 1.23–33.79, respectively). With respect to celiac disease characteristic, a low adherence to a gluten free diet was independently associated with the presence of adenomas (OR 6.78 CI 1.39–33.20 p = 0.01).

ConclusionsCeliac disease was not associated with an increased risk of colorectal neoplasia. Nonadherence to a strict gluten free diet was associated with the presence of adenomas. Further studies addressing celiac disease characteristics are needed to confirm this observation.
