Objective. Celiac disease (CD) has strongly been established as associated with some site-specific gastrointestinal malignancies. On the contrary, according to the few reports available, the risk of colon carcinoma in CD patients has been described similar to that of general population. In this cohort study, we describe the risk of colon carcinoma in a group of Italian celiac patients. Materials and methods. The study population included all CD patients diagnosed at the Collaborating Centers of the Italian Registry of CD between 1st January 1982 and 31st December 2006. Upon diagnosis of CD and upon at every subsequent clinical control, the Collaborating Centers filled in a validated form for each CD patient reporting information about demographic data, possible occurrence of a neoplasm and adherence to a gluten-free diet. Results. Out of 1757 celiac patients enrolled, 6 developed a colon carcinoma during the follow-up period (mean: 18.1 years). The standardized incidence ratio (SIR) resulted 0.29 (95% CI = 0.07-0.45). Stratifying the risk for the dietary gluten intake, the SIR dropped to 0.07 (95% CI = 0.009-0.27) for CD patients with a strict adherence to a gluten-free diet. Conclusion. We confirm the previous finding that there is low risk to develop a colon cancer in celiac patients. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented about enterocyte apoptosis prevention by a decapeptide from durum wheat of in vitro gliadin peptide-induced apoptosis in small-bowel mucosa from coeliac patients.
