A Cell Marker Atlas to Distinguish Metaplastic Transitions in Human Esophagus and Stomach

open access: yesCellular and Molecular Gastroenterology and Hepatology
Metaplasia is an adaptative response to injury and inflammation and can be a precursor to dysplasia and cancer. Metaplasia in the esophagus, termed Barrett’s esophagus, is the replacement of the stratified squamous epithelium by glandular tissue ...

Common features between neoplastic and preneoplastic lesions of the biliary tract and the pancreas [PDF]

open access: yes, 2019
The bile duct system and pancreas show many similarities due to their anatomical proximity and common embryological origin. Consequently, preneoplastic and neoplastic lesions of the bile duct and pancreas share analogies in terms of molecular ...

Intestinal Metaplasia of the Stomach

open access: yesVideo Journal and Encyclopedia of GI Endoscopy, 2013
AbstractIntestinal metaplasia (IM) of the stomach is associated with a very small increased risk of developing gastric cancer. Endoscopic surveillance has been proposed and advocated for populations at risk. Risk factors for IM include Helicobacter pylori infection, high salt intake, smoking, alcohol consumption, and chronic bile reflux.

Helicobacter pylori with stronger intensity of CagA phosphorylation lead to an increased risk of gastric intestinal metaplasia and cancer

open access: yesBMC Microbiology, 2011
Background Nearly all Taiwanese H. pylori stains are cagA-genopositive and encode CagA protein. In this study, we evaluated whether different intensity of tyrosine phosphorylated-CagA (p-CagA) had an impact on the clinical diseases and histological ...

Modern strategy of patient management in pre-cancer stomach diseases: diagnostic approaches and therapeutic possibilities

open access: yesЛечащий Врач, 2021
Stomach cancer represents a serious medical and social problem, both for most of the countries, and for Russia. Patients with chronic atrophic gastritis or intestinal metaplasia have increased risk of stomach adenocarcinoma development.

Origin of adenocarcinoma in Barrett's esophagus: P53 and Ki67 expression and histopathologic background Origem do adenocarcinoma no esôfago de Barrett: bases histopathológicas e expressão dos genes p53 e Ki67

open access: yesClinics, 2005
Barrett's esophagus is the substitution of squamous epithelium of the distal esophagus by columnar epithelium. Intestinal metaplasia in Barrett's esophagus is considered to be the main risk factor for the development of adenocarcinoma.

Volumetric laser endomicroscopy and its application to Barrett's esophagus: results from a 1,000 patient registry. [PDF]

open access: yes, 2019
Volumetric laser endomicroscopy (VLE) uses optical coherence tomography (OCT) for real-time, microscopic cross-sectional imaging. A US-based multi-center registry was constructed to prospectively collect data on patients undergoing upper endoscopy during

Expression profile of mucins (MUC2, MUC5AC and MUC6) in Helicobacter pylori infected pre-neoplastic and neoplastic human gastric epithelium

open access: yesMolecular Cancer, 2006
Background Helicobacter pylori (H. pylori) causes gastritis and intestinal metaplasia (IM) that may evolve to gastric carcinoma. The objective of this study was to compare the profile of mucins in the progressive stages of H.
