Abstract
AIM: To evaluate the morphological and pathologic features of polyps in colorectal cancer (CRC) patients.
METHODS: A total of 3166 patients underwent colonoscopy between April 2009 and August 2012 at the First People's Hospital of Yangzhou. These patients were divided into two groups: CRC and non-CRC. Sex, age, characteristics of adenomatous polyps (location, number, size, morphology and pathology), and CRC were recorded. The morphological and pathologic features of polyps in the two groups were analyzed.
RESULTS: Of 3022 cases who underwent total colonoscopy, 142 were diagnosed with CRC (4.7%), and 2880 had non-CRC diseases. CRC patients had higher prevalences of polyps, multiple polyps and high-risk adenomas than non-CRC patients (P = 0.017, 0.02, 0.002). Although CRC patients had a higher frequency of tubular or villous adenomas (P < 0.05), no significant differences in size of the lesion or pathological type were observed between the two groups. The frequency of right colonic lesions in CRC patients was significantly higher than that in non-CRC patients (37.4% vs 27.5%, P = 0.007).
CONCLUSION: There are high detection rates of colon polyps and high-risk adenomas in CRC patients. The quality of colonoscopy should be stressed in CRC patients.
