N2 - Background: The activity of epithelial lactase (LCT) associates with a polymorphism 13910. bp upstream the LCT-encoding gene (LCT-13910C> T). The relationship between LCT-13910C> T polymorphism and risk for colorectal cancer is unclear. Aims: We examined the relationship between the LCT-13910C> T polymorphism causing lactose intolerance and risk for colorectal cancer/polyps onset in the Italian population. Patients and methods: 793 subjects (306 with colorectal cancer, 176 with polyps and 311 controls) were genotyped for the LCT-13910C> T variant by TaqMan real time-PCR. Results: Lactose malabsorption linked to the CC genotype did not associate with an increased risk for either colorectal cancer (OR = 1.041; 95% CI = 0.751-1.442; p= 0.868) or polyps (OR = 0.927; 95% CI = 0.630-1.363; p= 0.769). There was no association with colorectal cancer/polyps site. 60% of the subjects overall bore the CC genotype. Conclusion: In the Italian population the LCT-13910C> T polymorphism is not associated to the risk for colorectal cancer or polyps.
