Association between serum lipid profiles and colorectal adenoma in Chinese population

Abstract Background Dyslipidemia may play an important role in the development of colorectal adenomas. This study aims to investigate the serum lipid profiles in patients with colorectal adenomas and determine correlation between dyslipidemia and colorectal adenomas. Methods This retrospective case - control study included 2,960 patients with colorectal adenomas, and 1,263 participants with normal colonoscopy results served as controls. The serum levels of lipids were measured and comparison was made between patients and controls. The association between serum lipid levels, as well as other factors and colorectal adenoma was evaluated by multivariate regression logistic analysis. Results The serum levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and apoliprotein B (ApoB) were significantly elevated in patients with colorectal adenomas compared with controls. The proportions of subjects with high LDL, high TC, high TG or multiple abnormality were significantly larger in adenoma group than the control group. Multivariate analysis suggested that serum levels of TC and TG were in significant associations with risk of both nonadvanced and advanced colorectal adenoma. Conclusions Abnormal lipid profiles are associated with the risk of colorectal adenoma. Elevated serum TC and TG were correlated with the occurrence of adenoma, thus may serve as practical markers for classifying risk of colorectal adenoma.
