BACKGROUND: The Siewert classification system for gastroesophageal junction adenocarcinoma has provided morphological and topographical information to help guide surgical decision-making. Evidence has shown that Siewert I and III tumors are distinct entities with differing epidemiologic and histologic characteristics and distinct patterns of disease progression, requiring different treatment. Siewert II tumors share some of the characteristics of type I and III lesions, and the surgical approach is not universally agreed upon...

An endoscopic examination revealed a mass in the distal esophagus of a 9-year-old intact male bulldog. Histopathologically, the mass was composed of cuboidal to columnar neoplastic epithelial cells and extended from the squamous epithelium of the esophageal mucosa, indicating that the tumor was derived from Barrett's esophagus. Moreover, highly atypical foci that exhibited a cribriform pattern and high mitotic indices were also observed. The epithelial cells on the surface of the lesion often produced mucus that was positive for Alcian blue and immunohistochemically positive for MUC5AC...

BACKGROUND AND STUDY AIMS : Accurate endoscopic detection of dysplasia in patients with Barrett's esophagus (BE) remains a major clinical challenge. The current standard is to take multiple biopsies under endoscopic image guidance, but this leaves the majority of the tissue unsampled, leading to significant risk of missing dysplasia. Furthermore, determining whether there is submucosal invasion is essential for proper staging. Hence, there is a clinical need for a rapid in vivo wide-field imaging method to identify dysplasia in BE, with the capability of imaging beyond the mucosal layer...

Esophageal cancer is the eighth most common malignant tumor worldwide, and the number of incidences of esophageal adenocarcinoma is increasing in the Western world. Despite improvements in perioperative treatment, the overall survival rate of patients with esophageal adenocarcinoma remains poor. Breast cancer type 1 susceptibility protein (BRCA1)-associated protein (BAP1) is located on chromosome 3p21, and it is an enzyme with ubiquitin carboxyl hydrolase activity that regulates cell growth. It interacts with BRCA1, and the nuclear localization of BAP1 is required for its tumor suppressor function...

The incidence of esophageal adenocarcinoma (EAC) has increased in many Western countries, and is higher in men than women. Some risk factors for EAC have been identified-mainly gastroesophageal reflux disease (GERD), Barrett's esophagus, obesity, and tobacco smoking. It is not clear whether interventions to address these factors can reduce risk of EAC, although some evidence exists for smoking cessation. Although consumption of alcohol is not associated with EAC risk, other exposures, such as physical activity, nutrition, and medication use, require further study...

The esophagus is a pivotal organ originating from anterior foregut that links the mouth and stomach. Moreover, its development involves precise regulation of multiple signal molecules and signal transduction pathways. After abnormal regulation of these molecules in the basal cells of the esophagus occurs, multiple diseases, including esophageal atresia with or without tracheoesophageal fistula, Barrett esophagus, gastroesophageal reflux, and eosinophilic esophagitis, will take place as a result. Furthermore, expression changes of signal molecules or signal pathways in basal cells and the microenvironment around basal cells both can initiate the switch of malignant transformation...

BACKGROUND AND AIM: Liquid nitrogen cryotherapy (LNC) allows increased depth of ablation compared to radiofrequency ablation (RFA) in Barrett's esophagus (BE). Expert centers may use LNC over RFA to ablate Barrett's esophagus after endoscopic resection of intramucosal cancer (IMCA). The aim of our study was to: 1) evaluate the safety and efficacy of LNC ablation in patients with BE and IMCA and 2) to evaluate the progression to invasive disease despite therapy. METHODS: This was a multicenter, retrospective study of consecutive patients with BE who received LNC following endoscopic mucosal resection (EMR) of IMCA...

Objective To clarify the relationship between the shape and circumferential location of non-circumferential short-segment Barrett's esophagus (SSBE). Methods We examined 3,788 subjects (2,497 males, 1,291 females; mean age 52.4 years) who underwent upper GI endoscopy as part of a detailed medical checkup. The presence of columnar-appearing mucosa ≥10 mm long in the distal esophagus was diagnosed as BE and then divided into circumferential and non-circumferential localized types. Localized SSBE was further divided into round and sharp types based on the shape of the proximal margin...

Adjustments for lead and length time bias has been used when examining apparent survival advantages from screening procedures. However, these estimates depend on several assumptions and are modeled from malignancies that are fairly common and large cohorts are available. In smaller retrospective cohorts, adjustments themselves may be based on estimates that may not be biological nor statistically accurate, which can lead to divergent results as has been found in several recent studies of screening in Barrett's esophagus...

BACKGROUND AND AIMS: Wide-area transepithelial sampling (WATS) with computer-assisted 3-dimensional analysis is a sampling technique that combines abrasive brushing of the Barrett's esophagus (BE) mucosa followed by neural network analysis to highlight abnormal-appearing cells. METHODS: We performed a randomized trial of referral BE patients undergoing surveillance at 16 medical centers. Subjects received either biopsy followed by WATS, or vice versa. The primary outcome was rate of detection of HGD/EAC using WATS in conjunction with biopsy compared with biopsy alone using standard histopathologic criteria...

In this systematic review, we summarize the evidence on prognosis and prognostic factors of pediatric GERD. A structured search of Embase and MEDLINE/PubMed (inception to April 2016) yielded 5365 references; four publications met our inclusion criteria (risk of bias moderate-high). Definitions and outcome measures varied widely between studies. The percentage of children with a diagnosis of GERD with esophagitis that had persisting symptoms and/or were on anti-reflux medication at follow-up (12 months to >5 years) ranged from 23% (weekly symptoms) to 68% (anti-reflux medication), depending on definition used...

Esophageal adenocarcinoma (EAC) has one of the fastest increases in incidence of any cancer, along with poor five-year survival rates. Barrett's esophagus (BE) is the main risk factor for EAC, however the mechanisms driving EAC development remain poorly understood. Here, transcriptomic profiling was performed using RNA-sequencing (RNA-seq) on premalignant and malignant Barrett's tissues to better understand this disease. Machine-learning and network analysis methods were applied to discover novel driver genes for EAC development...

BACKGROUND & AIMS: Little is known about the causes of heartburn in patients with gastro-esophageal reflux disease (GERD). Visible epithelial damage is seldom associated with symptom severity, evidenced by the significant symptom burden in patients with non-erosive reflux disease (NERD) compared to patients with erosive reflux disease (ERD) or Barrett's esophagus (BE). We studied the distribution of mucosal nerve fibers in patients with NERD, ERD, and BE, and compared the results with those of healthy subjects...

Background and study aims Enhanced endoscopic imaging with chromoendoscopy may improve dysplasia recognition in patients undergoing assessment of Barrett's esophagus (BE). This may reduce the need for random biopsies to detect more dysplasia. The aim of this study was to assess the effect of magnification endoscopy with I-SCAN (Pentax, Tokyo, Japan) and acetic acid (ACA) on dysplasia detection in BE using a novel mucosal and vascular classification system. Methods BE segments and suspicious lesions were recorded with high definition white-light and magnification endoscopy enhanced using all I-SCAN modes in combination...

Endoscopic surveillance in Barrett's esophagus (BE) has numerous limitations and thus provides several opportunities for improving the effectiveness of our current surveillance strategies. Several risk stratification and prediction tools have been investigated to identify patients at highest risk for progression to esophageal adenocarcinoma (EAC). Persistence of non-dysplastic BE (NDBE) has been proposed as an indicator of lower risk of progression to EAC. This editorial highlights the variable results and methodologies in studies evaluating persistence of NDBE as a risk stratification tool in the surveillance of BE patients and provides guidance for optimizing outcomes in BE patients enrolled in surveillance programs...
