The Risk Of Suffering From Colorectal Cancer In Diabetes Mellitus Patients And Its Relevance Analysis

Objective:To provid the basis for the etiology, prevention, and colorectal cancer screening by studying the correlation between diabetes and colorectal cancer.Methods:A retrospective analysis from March 2013 to March 2015 in Shanxi Dayi Hospital and First Affiliated Hospital of Shanxi Medical University hospital. 312 patients were confirmed by pathology and consists of the case group. Results of testing, history of diabetes, family history of diabetes, and family history of colorectal cancer should be included in the medical records. Matching the principle of non-selection, 423 patients with colorectal cancer during the same period of hospitalization consists of the control group. Logistic regression was used to analysis the correlation between colorectal cancer and diabetes. Courses of diabetes and locations of colorectal cancer were recorded and analyzed with SPSS 19.0.Results:Logistic regression analysis showed history of diabetes and family history of colorectal cancer are independent risk factors for colorectal cancer. Cases of diabetes group <5years,5 to 10 years,10 to 20 years,>20 years OR values are 2.869、3.130、3.228、1.267.Diabetes and the locations of colorectal cancer were statistically significant(P<0.05).Conclusion:(1)Diabetes was a independent risk factor for colorectal cancer by increasing its risk of incidence. (2) The risk of colorectal cancer increases with increasing duration of diabetes over time, but risk decreases if the duration was over 20 years. (3)Caused bydiabetes increases the risk of colon cancer,With higher incidence of right colon cancer.
