Abstract:
Objective To retrospectively analyse the factors related to the risk of malignant change in relation with various colorectal polyps. Methods Data on a total of 820 patients (900 polyps), who had undergone polypectomy between 1997 and 2001 were collected. The relation between colorectal cancer and polyps characteristics was assessed by Logistic Regression and Chi square. Results The risk of malignant change was significantly related with the size of polyps, histology of polyps, grade of dysplasia, pathological changes of mucosa, sessile or pedunculated polyps. Conclusion High grade dysplasia, large size, adenoma, absence of a stalk, and ulcerous mucosa were confirmed as the major predictors. The likelihood of malignant degeneration of colorectal polyps seemed to be correlated with the number of the above mentioned risk factors present
