Key clinical point: The risk for incident colorectal cancer (CRC) events increases with the presence of normal-high fasting plasma glucose (FPG), impaired fasting glucose (IFG), and diabetes mellitus (DM).
Major finding: Compared with normal FPG, the presence of normal-high FPG (hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.03-1.18), IFG (HR, 1.24; 95% CI, 1.13-1.37), and DM (HR, 1.36; 95% CI, 1.19-1.55) was associated with a higher incidence rate of CRC.
Study details: Findings are from a retrospective observational study of 1,441,311 individuals who underwent annual health checkups. Included patients did not have colorectal polyps, Crohn's disease, and/or ulcerative colitis and were not taking antidiabetic medications.
