Esophageal adenocarcinoma (EAC) develops from Barrett's esophagus (BE), a condition where the normal squamous epithelia is replaced by specialized intestinal metaplasia in response to chronic gastroesophageal acid reflux. In a minority of individuals, BE can progress to low- and high-grade dysplasia and eventually to intra-mucosal and then invasive carcinoma. BE provides researchers with a unique model to characterize the process by which a carcinoma arises from its precursor lesion. Molecular studies of BE have demonstrated that it is not simply a metaplastic tissue, but rather it harbors frequent alterations that are also present in dysplastic BE and in EAC...

BACKGROUND: Histological assessment of dysplasia in Barrett's esophagus (BE) has high inter-observer variability. Hence, use of ancillary markers for early detection of dysplasia in BE is an important clinical question. METHODS: In this retrospective study consecutive cases of BE (n = 59), over a period of 4 years were included. Hematoxylin and eosin stained sections were reviewed independently by 3 senior qualified pathologists, who graded the dysplasia according to the Vienna Classification system and inter-observer agreement was analysed using the Kappa statistics...

BACKGROUND: Perioperative opioid use is associated with poor survival in patients with esophageal squamous cell carcinoma. The most common histological type of esophageal cancer in western countries is adenocarcinoma. The objective of this study was to evaluate the association between intraoperative opioid consumption and survival in patients with adenocarcinoma and squamous cell carcinoma of the esophagus. METHODS: Records of patients who had undergone esophageal cancer surgery between January 2000 and January 2017 were reviewed...

BACKGROUND: Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a neoplasm composed of both exocrine and endocrine carcinomas, each comprising at least 30% of the tumor. MANEC can occur in various organs of the gastrointestinal tract, including the esophagus, stomach, and colon. We herein provide the first case report of surgically resected MANEC arising in Barrett's esophagus (BE). CASE PRESENTATION: A 70-year-old man presenting with abdominal pain was referred to our hospital...

Centrosome abnormalities are a typical hallmark of human cancers. However, the origin and dynamics of such abnormalities in human cancer are not known. In this study, we examined centrosomes in Barrett's esophagus tumorigenesis, a well-characterized multistep pathway of progression, from the premalignant condition to the metastatic disease. This human cancer model allows the study of sequential steps of progression within the same patient and has representative cell lines from all stages of disease. Remarkably, centrosome amplification was detected as early as the premalignant condition and was significantly expanded in dysplasia...

Aspirin use is associated with reduction of esophageal adenocarcinoma but it is not known if it does so by preventing the development of Barrett's esophagus or by reducing neoplastic progression in patients with Barrett's esophagus. There is sparse literature to support the former assumption especially in women. This study by Jovani et al. based on Nurses' Health Study reports 27% lower risk of Barrett's esophagus among women using aspirin. The protective effect seems to increase with higher frequency and longer duration of aspirin use...

The exponential rise in incidence of esophageal adenocarcinoma (EAC), paired with persistently poor survival, continues to drive efforts to improve and optimize screening and surveillance practices. While advancements in endoscopic therapy have generated a shift in management and significantly improved the outcomes of patients with early-stage EAC, the majority of prevalent EAC continues to be diagnosed at advanced stages, remaining ineligible for curative therapy. Barrett's esophagus (BE) screening, when applied to high-yield target populations, using minimally or noninvasive accurate tests, followed by endoscopic surveillance to detect prevalent or incident dysplasia/EAC (which can then be treated successfully) is the cornerstone of the current BE management paradigm...

The stratified squamous epithelium of the esophagus shows a proliferative basal layer of keratinocytes that undergo terminal differentiation in overlying suprabasal layers. Esophageal pathologies, including eosinophilic esophagitis, gastroesophageal reflux disease, Barrett's esophagus, squamous cell carcinoma, and adenocarcinoma, cause perturbations in the esophageal epithelial proliferation-differentiation gradient. Three-dimensional (3D) culture platforms mimicking in vivo esophageal epithelial tissue architecture ex vivo have emerged as powerful experimental tools for the investigation of esophageal biology in the context of homeostasis and pathology...

PURPOSE OF REVIEW: To provide new concepts regarding the early pathologic changes of gastroesophageal reflux disease (GERD) that are associated with damage to the lower esophageal sphincter (LES). RECENT FINDINGS: A body of evidence exists that cardiac mucosa is a metaplastic esophageal epithelium rather than a normal gastric epithelium. Recent studies in asymptomatic volunteers suggest a potential mechanism for cardiac metaplasia in the squamous epithelium of the esophagus...

Risk stratification of patients with Barrett's esophagus (BE) is based on diagnosis of low-grade dysplasia (LGD). LGD has a poor interobserver agreement and a limited value for prediction of progression to high-grade dysplasia or esophageal adenocarcinoma. Specific reproducible histologic criteria may improve the predictive value of LGD. Four gastrointestinal pathologists examined 12 histologic criteria associated with LGD in 84 BE patients with LGD (15 progressors and 69 nonprogressors). The criteria with at least a moderate (kappa, 0...

Esophageal adenocarcinoma (EAC) is one of the deadliest carcinoma faced by gastroenterologists. Any insult to esophagus that causes replacement of normal squamous epithelium with columnar intestinal epithelium is labelled as the initiating event of the metaplasia-neoplasia sequence. Barrett's esophagus is the precursor to EAC. Currently, endoscopically obtained biopsies are used to detect neoplastic changes in patients with Barrett's esophagus (BE); however, it is not cost effective and hence a better screening modality is needed...

Background: Loss of heterozygosity of p53 along with aneuploidy is deemed to be the early molecular steps in Barrett metaplasia-dysplasia-adenocarcinoma sequence. Objective biomarkers need to be used along with microscopy for risk stratification to predict the progression of Barrett esophagus (BE) to carcinoma. Aim: This study aims to study p53 protein expression in dysplasia and correlate the same with morphology in BE. Materials and Methods: A time-bound study was conducted from January 2011 to June 2015...

Barrett's esophagus is the only known pre-cancerous lesion for esophageal adenocarcinoma and is diagnosed by high-definition white light endoscopy demonstrating a columnar-lined esophagus along with biopsy evidence of intestinal metaplasia. With accurate performance and reporting of the endoscopic procedure, an evidence-based management strategy can be developed for treatment of Barrett's dysplasia. However, cross-sectional data demonstrate that there is still inconsistency among gastroenterologists in performance and reporting of endoscopic findings in patients with Barrett's esophagus...

The incidence of esophageal adenocarcinoma has been increasing in Western countries over the past several decades. Though Barrett's esophagus, in which the normal esophageal squamous epithelium is replaced with metaplastic intestinalized columnar cells due to chronic damage from gastroesophageal reflux, is accepted as the requisite precursor lesion for esophageal adenocarcinoma, the Barrett's esophagus cell of origin and the molecular mechanism underlying esophageal epithelial metaplasia remain controversial...

Over the past two decades, evidence has accumulated to challenge the traditional view that cardiac mucosa, which is comprised exclusively of mucus glands, is the normal lining of the most proximal portion of the stomach (the gastric cardia). There is now considerable evidence to suggest that cardiac mucosa develops as a GERD-induced, squamous-to-columnar esophageal metaplasia in some, if not all, cases. Although cardiac mucosa lacks the goblet cells commonly required for a histologic diagnosis of intestinal metaplasia, cardiac mucosa has many molecular features of an intestinal-type mucosa, and appears to be the precursor of intestinal metaplasia with goblet cells...

Barrett's esophagus is a condition in which metaplastic columnar epithelium replaces stratified squamous epithelium in the distal esophagus. This condition occurs due to chronic gastroesophageal reflux disease and is a risk factor for the development of esophageal adenocarcinoma. Multiple clinical guidelines have been published around the world in recent years to assist gastroenterologists in the management of these patients and have evolved as new data have become available. While some information such as surveillance technique has not drastically changed, there has been an evolution over the years in diagnostic criteria, screening and endoscopic therapy with a variety of subtle differences among the different guidelines...

Since the early 1970s, the incidence of esophageal adenocarcinoma (EA) has increased dramatically in most Western populations while the incidence of esophageal squamous cell carcinoma has decreased. As a result, EA has become the predominant subtype of esophageal cancer in North America and Europe and is an important contributor to overall cancer mortality. Barrett's esophagus (BE), a metaplastic columnar epithelium of the distal esophagus, is the known precursor lesion for EA. EA and BE occur more frequently in white men over 50 years old, as well as in people with frequent symptoms of gastroesophageal reflux, in smokers, and in people who are obese...
