متن کاملMolecular characteristics of colorectal serrated polyps and hyperplastic polyps
The serrated neoplasia pathway of colorectal carcinogenesis is characterized by BRAF mutation and aberrant DNA methylation, which have not been reported on Korean patients. The aim of this study was to investigate BRAF mutation and DNA methylation in colorectal serrated polyps and the right colon.Between 2005 and 2013, 146 colon polyps (47 tubular adenomas [TAs], 53 traditional serrated adenoma...
متن کاملImmunohistochemical and Molecular Features of Gastric Hyperplastic Polyps
Design: 15 large hyperplastic polyps (>1 cm), including 4 with dysplastic foci, 10 small hyperplastic polyps (≤1 cm), and 9 gastric adenomas were evaluated for immunohistochemical expression of MGMT, MLH-1, β-catenin, p27, p16, and p53. Polyps with dysplasia or abnormal β-catenin expression were assessed for APC and β-catenin (CTNNB1) mutations. Large hyperplastic polyps and adenomas were analy...
