Prevalence of Proximal Serrated Polyps and Conventional Adenomas in an Asymptomatic Average-Risk Screening Population
BACKGROUND/AIMS Detection of proximal serrated polyps (PSPs) is increasingly recognized as a new qualitative target for colonoscopy. The aims of this study were to assess the detected prevalence of PSPs and synchronous adenomas in an asymptomatic average-risk screening cohort and to evaluate potential factors associated with detection of PSPs. METHODS The study included 1,375 asymptomatic ave...
متن کاملScreening, management and surveillance for the sessile serrated adenomas/polyps.
The incidence and mortality rates from right-sided colorectal cancers (CRCs) have not decreased, compared with the significant reduction of CRCs in the left colon in recent years. It is likely that a significant proportion of right-sided CRCs evolve from undetected sessile serrated adenomas/polyps (SSA/Ps) in the primary colonoscopy. Increasing evidences suggest that SSA/Ps are high-risk lesion...
متن کاملDiagnostic value of distal colonic polyps for prediction of advanced proximal neoplasia in an average-risk population undergoing screening colonoscopy.
BACKGROUND For colorectal cancer screening, the predictive value of distal findings in the ascertainment of proximal lesions is not fully established. The aims of this study were to assess distal findings as predictors of advanced proximal neoplasia and to compare the predictive value of endoscopy alone vs. combined endoscopic and histopathologic data. METHODS Primary colonoscopy screening wa...
متن کاملβ-catenin helices in the cytoplasm of sessile serrated adenoma/polyps and conventional colorectal adenomas.
Initiation and progression in conventional adenomas is triggered by deregulation of WNT/β-catenin signaling. In the absence of WNT signal (off-state), β-catenin prevents phosphorylation of GSK3β, leading to aberrant nuclear accumulation in human tumors. It has been postulated that mutations in the β-catenin gene are always associated with a morphologically-neoplastic course. While investigating...
متن کاملInterendoscopist variability in proximal colon polyp detection is twice higher for serrated polyps than adenomas
AIM To assess the interendoscopist variability in the detection of colorectal polyps according to their location and histological type. METHODS This study was a retrospective analysis of prospectively collected data from a regional colorectal cancer (CRC) screening program; 2979 complete colonoscopies from 18 endoscopists were included. Variability in performance between endoscopists for dete...
