The prevalence of gastric heterotopia of the proximal esophagus is underestimated, but preneoplasia is rare - correlation with Barrett’s esophagus

BMC Gastroenterology, 2017
Background The previously reported prevalence of gastric heterotopia in the cervical esophagus, also termed inlet patch (IP), varies substantially, ranging from 0.18 to 14%.

Relationship between p53 expression and gastric cancers in cardia and antrum [PDF]

, 2008
Background: The mutations in p53 gene and accumulation of p53 protein are the most common genetic events in gastric carcinomas. The present study was conducted to compare the frequency of p53 gene overexpression in a consecutive series of adenocarcinomas

A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

BMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐

Clonal cell states link gastroesophageal junction tissues with metaplasia and cancer

Nature Communications
Barrett’s esophagus is a common type of metaplasia and a precursor of esophageal adenocarcinoma. However, the cell states and lineage connections underlying the origin, maintenance, and progression of Barrett’s esophagus have not been resolved in humans.

Outcomes of Radiofrequency Ablation for Dysplastic Barrett’s Esophagus: A Comprehensive Review

Gastroenterology Research and Practice, 2016
Barrett’s esophagus is a condition in which the normal squamous lining of the esophagus has been replaced by columnar epithelium containing intestinal metaplasia induced by recurrent mucosal injury related to gastroesophageal reflux disease.

GERD and Upper Aerodigestive Tract Cancer Risk: A Systematic Review and Meta‐Analysis

The Laryngoscope, EarlyView.
ABSTRACT Objective Gastroesophageal reflux disease (GERD) is highly prevalent, yet its association with upper aerodigestive tract (UADT) cancers beyond esophageal adenocarcinoma remains incompletely defined. This systematic review and meta‐analysis aimed to quantify the risk of specific UADT cancers in individuals with GERD.
