Clinica Characteristics Of Adenomatous Polyps In Colorectal Cancer

Objective To evaluate the morphological and pathologic features of polyps in CRC patients.Methods A total of3166cases underwent colonoscopy between April2009and August2012in The First People’s Hospital of Yangzhou. Turn them into two groups:CRC, non-CRC. And recorded sex, age, adenomatous polyps characteristics (location, number, size, morphology and pathology)、CRC and so on. To analysis the morphological and pathologic features of polyps in the two groups.Results3022cases underwent total colonoscopy.142cases of CRC (4.7%),while2880cases in non-CRC. CRC patients had a higer prevalence of polyps, multiple polyps and high-risk adenoma than non-CRC (P=0.017, P=0.02, P=0.002); In CRC patients had a higher frequency of tubular or villous adenomas (P<0.05), but the two groups had no significant difference in terms of the size of the lesion, pathological type (P>0.05); right colonic lesion proportion in CRC patients was higher than that in non-CRC (37.4%vs27.5%, P=0.007), there was statistical significance.Conclusion There are high detection rates of colon polyps and high-risk adenoma in CRC patients, so we should pay attention to and improved the quality of colonoscopy in CRC patients.
