Abstract
PURPOSE: To determine if there is an association between diverticular disease and colon cancer diagnoses with a secondary outcome of assessing other known risk factors for colon cancer. Colon cancer and diverticular disease have many shared symptoms and risk factors; the association between the two has been debated for many years. METHODS: 36 cases of colon cancer and 144 age- and sex-matched controls were identified from records at an outpatient endoscopy center in Georgia. These cases and controls then were subject to a retrospective chart review to obtain any known risk factor data points for both diverticular disease and colon cancer. A traditional conditional logistic regression and a stepwise conditional logistic regression model were used to analyze the data using significant data points (P < 0.05). RESULTS: The final stepwise model found that systolic blood pressure (aOR = 1.027, 95% CI = 1.001 to 1.053), history of polyps (aOR = 0.106, 95% CI = 0.029 to 0.387), exercise (aOR = 0.311, 95% CI = 0.029 to 0.387), and history of diverticular disease (aOR = 0.269, 95% CI = 0.091 to 0.795) were protective factors significantly associated with colon cancer. CONCLUSIONS: Presence and history of the removal of colorectal polyps, presence or history of diverticular disease, and exercise pose as protective factors against development of colon cancer.
