Given the comparable strains of high-risk human papillomavirus (HPV) present in a subset of Barrett's dysplasia and esophageal adenocarcinoma as in head and neck squamous cell carcinomas and the anatomical proximity of both lesions, we hypothesized that oral sex may increase the risk of Barrett's dysplasia/esophageal adenocarcinoma. Therefore, we compared the sexual behavior of patients with Barrett's dysplasia/esophageal adenocarcinoma and controls (hospital, reflux, and Barrett's metaplasia) to explore a plausible mechanism of viral transmission to the lower esophagus...

Background & Aims: Effective therapeutic approaches are urgently required to tackle the alarmingly poor survival outcomes in esophageal adenocarcinoma (EAC) patients. EAC originates from within the intestinal-type metaplasia, Barrett's esophagus, a condition arising on a background of gastroesophageal reflux disease and associated inflammation. Methods: This study used a druggable genome small interfering RNA (siRNA) screening library of 6022 siRNAs in conjunction with bioinformatics platforms, genomic studies of EAC tissues, somatic variation data of EAC from The Cancer Genome Atlas data of EAC, and pathologic and functional studies to define novel EAC-associated, and targetable, immune factors...

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is safe and effective for eradicating Barrett's esophagus (BE), but associated with significant postprocedural pain. Alternatively, balloon-based focal cryoablation (CRYO) has recently been developed, which preserves the extracellular matrix and might therefore be less painful. Although data for CRYO are still limited, uncontrolled studies suggest comparable safety and efficacy to RFA in eradicating limited BE areas. Therefore, secondary endpoints such as pain might become decisive for treatment selection...

Muhammad Ali Khan, Colin W Howden
Proton pump inhibitors (PPIs) have been in use since the early 1990s and play a crucial role in the management of a number of conditions affecting the upper gastrointestinal tract, including gastroesophageal reflux disease, Barrett esophagus, eosinophilic esophagitis, and dyspepsia. PPIs also play an important role in the treatment of Helicobacter pylori infection and in the prevention of upper gastrointestinal tract ulcers and bleeding among patients taking antiplatelet therapy and/or nonsteroidal anti-inflammatory drugs...

AIM AND METHODS: The Japan Esophageal Society created a working committee group consisting of 11 expert endoscopists and 2 pathologists with expertise in Barrett's esophagus (BE) and esophageal adenocarcinoma. The group developed a consensus-based classification for the diagnosis of superficial BE-related neoplasms using magnifying endoscopy. RESULTS: The classification has three characteristics: simplified, an easily understood classification by incorporating the diagnostic criteria for the early gastric cancer, including the white zone and demarcation line, and the presence of a modified flat pattern corresponding to non-dysplastic histology by adding novel diagnostic criteria...

EDITORIAL
Colin W Howden
In this edition of the American Journal of Gastroenterology, Wang and colleagues report the results of an analysis of six different case-control studies examining the relationship between Helicobacter pylori (H. pylori) infection and Barrett's esophagus. They present a cogent argument that there is an inverse association between these two that is mediated via GERD. This is broadly consistent with previous reports. While further establishing this inverse association, the findings should not materially influence our routine clinical practice regarding GERD or H...

BACKGROUND & AIMS: MicroRNA (miRNA) is highly stable in biospecimens and provides tissue-specific profiles, making it a useful biomarker of carcinogenesis. We aimed to discover a set of miRNAs that could accurately discriminate Barrett's esophagus (BE) from normal esophageal tissue and to test its diagnostic accuracy when applied to samples collected by a non-invasive esophageal cell sampling device. METHODS: We analyzed miRNA expression profiles of 2 independent sets of esophageal biopsy tissues collected during endoscopy from 38 patients with BE and 26 patients with normal esophagus (controls) using Agilent microarray and Nanostring counter assays...

REVIEW
Ernst J Kuipers, Manon C Spaander
Barrett's esophagus (BE) is a very common condition. We have obtained fairly profound knowledge of the natural history of this condition. This results from many cross-sectional and cohort studies, many describing patients undergoing long-term surveillance. Their consent to use their clinical data has improved our knowledge to the benefit of these same and other patients. The prevalence of BE increases with age both in men and in women. This increase starts at a younger age in men than in women. The incidence of high-grade dysplasia and cancer in BE depends on segment length, gender, and age...

BACKGROUND & AIMS: Radiofrequency ablation (RFA) is effective treatment for Barrett's esophagus (BE). However, some patients have recurrence after complete eradication of intestinal metaplasia (CEIM). We investigated the incidence of and factors associated with BE recurrence, with or without neoplasia, after RFA and CEIM using data from the national Veterans Affairs (VA) healthcare system. METHODS: We performed a retrospective cohort study of Veterans with BE treated by RFA from 2005 through 2016 with follow-up endoscopy...

A 62-year-old male with long-standing esophageal reflux underwent endoscopy at an outside institution that reported multiple polypoid lesions in upper esophagus and a small focal area of nodular mucosa at the gastroesophageal junction(GEJ). Biopsies of the proximal esophageal polyps demonstrated hyperplastic mucosa with ulceration, reactive epithelial changes, and focal intestinal metaplasia. Biopsies from the nodular GEJ mucosa were described as Barrett's esophagus with low grade dysplasia. An upper endoscopy performed at our medical center found multiple semi-pedunculated esophageal polyps between 18-24 cm from the incisors (Figure A)...

BACKGROUND: Endoscopic eradication therapy (EET) is highly effective in treating dysplastic Barrett's esophagus (BE). Current surveillance intervals after complete remission of intestinal metaplasia (CRIM) are based on expert opinion. We performed a meta-analysis to compare BE detection in the first year to the subsequent ones METHODS: We searched MEDLINE, EMBASE, Scopus and Cochrane Central Register of Controlled Trials through 1 August 2017 for studies reporting IM and neoplasia detection after CRIM...

BACKGROUND: Minimally invasive methods have been described to detect Barrett's esophagus (BE), but are limited by subjectivity and suboptimal accuracy. We identified methylated DNA markers (MDMs) for BE in tissue and assessed their accuracy on whole esophagus brushings and capsule sponge samples. METHODS: Step 1: Unbiased whole methylome sequencing was performed on DNA from BE and normal squamous esophagus (SE) tissue. Discriminant MDM candidates were validated on an independent patient cohort (62 BE cases, 30 controls) by quantitative methylation specific PCR (qMSP)...

Background: Barrett's esophagus (BE) and esophageal dysplasia (ED) are frequently missed during screening and surveillance esophagoscopy because of sampling error associated with four-quadrant random forceps biopsy (FB). Aim: The aim of this article is to determine if wide-area transepithelial sampling with three-dimensional computer-assisted analysis (WATS) used adjunctively with FB can increase the detection of BE and ED. Methods: In this multicenter prospective trial, patients screened for suspected BE and those with known BE undergoing surveillance were enrolled...

OBJECTIVES: Epidemiological studies of Helicobacter pylori infection and risk of Barrett's esophagus (BE) have reported conflicting results. We examined the association between H. pylori infection and BE and sought to determine whether the association is mediated by gastroesophageal reflux disease (GERD) and to identify potential effect modifiers. METHODS: We used individual level data from 1308 patients with BE (cases), 1388 population-based controls, and 1775 GERD controls in the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON)...

Patient selection is suboptimal in most studies focused on identifying biological markers for neoplastic progression in Barrett's esophagus (BE). This study aims to describe a stringently selected community-based case-control cohort of non-dysplastic BE (NDBE) patients who progressed to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and BE patients who never progressed to be used for future biomarker studies. We identified all patients referred for endoscopic work-up of BE neoplasia at three tertiary referral centers for treatment of BE neoplasia between 2000 and 2013...

Risk factors for esophageal cancer include genetic factors (such as tylosis) and infectious agents. A variety of organisms have been implicated in esophageal carcinogenesis, either directly or indirectly. In this review, we explore the normal esophageal flora and how it may be controlled, and also the variety of organisms that may affect esophageal carcinogenesis, either directly or indirectly. The organisms with potential direct effects in squamous cell carcinoma include human papillomavirus (HPV), Epstein-Barr virus, and polyoma viruses...
