To investigate the clinical and pathological features of colonic polyp canceration and related risk factors of colon polyps, and explore clinicopathologic features and major risk factors of the canceration of polyps of colon polyps.

Totally 80 patients with colon polyps including 6 cases of cancerations and 20 patients with colon cancers were selected from Xuzhou Tumor Hospital Admissions. Those patients were divided into 74 cases of non cancer group and 26 cases of cancer group. The clinical data, the detection index and the statistical analysis were performed.

The clinical features of patients included 51 cases of multiple polyps, 30 cases of fatty liver, 13 cases of fecal occult blood positive, and 30 patients with colonoscopy. There were 218 polyps, 191 data intact, and 6 cases showed cancer (3.14%). Inflammatory polyps mainly occurred in rectum, cecum, and significant risk other than the colon. Tubular adenoma occurred mainly in the transverse colon. Sigmoid colon cancer colon polyps of the highest risk showed OR=2.30 (P<0.05). The cancer risk from high to low was from tubular villous adenoma to villous adenoma hair (P<0.01), and no difference in tubular adenoma cancer risk (P>0.05). There was no difference between the indexes of the canceration group and the non cancerous group (P>0.05). The single factor analysis showed pathological type, and the lesion were the main risk factors of malignant colonic polyps (P<0.05). Multi-factor regression analysis showed WBC, pathological type, and the lesion were the main risk factors of malignant colonic polyps (P<0.05).

The colonic polyps in male have higher incidence with fatty liver, hypertension and other pathological features, and are mainly tubular adenomas, inflammatory and hyperplastic polyps, with different lesions, pathological types occur and different cancer risk.
