BACKGROUND: Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade (small cell carcinoma or large cell carcinoma) and low grade (carcinoids). OBJECTIVE: The present study aims to assess clinical and pathological neuroendocrine esophageal tumors in a single oncologic center...

BACKGROUND: Endotherapy in cases of neoplastic Barrett esophagus (BE) relapse after successful initial endoscopic management is commonly accepted, but few studies analyze this topic and also take into account the metachronous lesions. AIMS: To evaluate the efficiency of endotherapy in the case of neoplastic BE relapse after successful complete endoscopic eradication of neoplastic BE and metaplastic BE. METHODS: Retrospective review of medical records was collected in a computerized and prospective manner between 2000 and 2015, in a single tertiary care center...

OBJECTIVES: Proton pump inhibitors (PPIs) have been used for treatment of Barrett's esophagus (BE) for many years. However, the connection between PPIs and esophageal adenocarcinoma (EAC) in patients with BE has still been controversial. The current systematic review and meta-analysis was designed to evaluate the association between PPIs and the risk of EAC or high-grade dysplasia (HGD) in patients with BE. METHODS: A systematic literature search of studies reporting the association between PPIs and the risk of EAC and/or HGD in patients with BE was conducted in PubMed, Embase, Web of Science and the Cochrane Library...

Redox signaling regulates physiological self-renewal, proliferation, migration and differentiation in gastrointestinal epithelium by modulating Wnt/β-catenin and Notch signaling pathways mainly through NADPH oxidases (NOXs). In the intestine, intracellular and extracellular thiol redox status modulates the proliferative potential of epithelial cells. Furthermore, commensal bacteria contribute to intestine epithelial homeostasis through NOX1- and dual oxidase 2-derived reactive oxygen species (ROS). The loss of redox homeostasis is involved in the pathogenesis and development of a wide diversity of gastrointestinal disorders, such as Barrett's esophagus, esophageal adenocarcinoma, peptic ulcer, gastric cancer, ischemic intestinal injury, celiac disease, inflammatory bowel disease and colorectal cancer...

BACKGROUND: Strictures are frequent complications of large endoscopic mucosal resections (EMR) and endoscopic submucosal dissections of the esophagus. Local or systemic steroid therapy has shown promise in the prevention of secondary stenosis. The aim of this study was to evaluate the safety and efficacy of systemic steroid therapy following endoscopic resection of at least hemi-circumferential esophageal mucosa. METHODS: This was a single-center retrospective study in a tertiary center...

REVIEW

In Barrett's esophagus, normal squamous epithelium is replaced by a metaplastic columnar epithelium as a consequence of chronic gastroesophageal reflux disease. There is a strong association with esophageal adenocarcinoma. In view of the increasing incidence of esophageal adenocarcinoma in the western world, it is important that more attention be paid to the progression of Barrett's esophagus toward esophageal adenocarcinoma. Recently, several molecular factors have been identified that contribute to the sequence towards adenocarcinoma...

Barrett's mucosa is one of the most important diseases in upper gastrointestinal system that caused by gastro-esophagus reflux. If left untreated, the disease will cause distal esophagus and gastric cardia adenocarcinoma. The malignancy risk is very high in short segment Barrett's mucosa. Therefore, lesion area segmentation can improve specialist decision for treatment. In this paper, we proposed a combined fuzzy method with active models for Barrett's mucosa segmentation. In this study, we applied three methods for special area segmentation and determination...

BACKGROUND: Barrett's esophagus is a precancerous lesion, and its identification with the early detection of dysplasia is of paramount importance to prevent adenocarcinoma onset. However, there is still debate on the correct pathological identification of Barrett's esophagus (and of associated dysplasia), and most studies have been conducted in an experimental setting. AIMS: To assess previous uncertain diagnoses of Barrett's (with and without dysplasia) via a second opinion of an expert pathologist in a real life setting...

BACKGROUND & AIMS: For patients with Barrett's esophagus (BE), the diagnosis of low-grade dysplasia (LGD) is subjective and reported outcomes vary. We analyzed data from a multicenter study of endoscopic therapy to identify factors associated progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in patients with LGD of the esophagus. METHODS: We performed a retrospective analysis of data from 255 patients with a primary diagnosis of LGD (78% men; mean age, 63 years) who participated in a randomized controlled trial of surveillance vs radiofrequency ablation in Europe...

Background. Barrett's esophagus is associated with an increased risk of adenocarcinoma. Dysplasia in Barrett's esophagus is a precursor to adenocarcinoma. Rarely, dysplastic polypoid lesions are superimposed on Barrett's esophagus. Most reported cases of polypoid dysplasia in Barrett's esophagus have been advanced on presentation and treated with esophagectomy. We describe two cases of polypoid changes in Barrett's esophagus and treatment with polypectomy followed by radiofrequency ablation. Cases. A 75 yo male presented with esophageal polyps, which on biopsy showed gastric cardia/foveolar mucosa with focal intestinal metaplasia without dysplasia...

Background and study aim Cryoablation can be used for the treatment of Barrett's esophagus (BE). A recent dosimetry study, using the CryoBalloon Focal Ablation System (CryoBalloon), demonstrated that 10-second ablations result in complete eradication of BE. However, the efficacy of 10-second ablation in a larger cohort of patients has not been investigated, nor has the potential of precise targeting of specific areas. The aim of the study was to assess the efficacy and performance (i. e. targeting of BE islands) of a 10-second cryoablation using the CryoBalloon...

Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transaminitis and AFP was 2524 ng/mL. Computed tomography of the abdomen revealed abnormal thickening of the esophagus and multiple metastatic masses throughout the liver...

BACKGROUND & AIMS: Many patients with a less than 1 cm segment of columnar metaplasia in 3 the distal esophagus, also called an irregular Z line, are encountered. These patients, often referred to as patients with Barrett's esophagus (BE), are enrolled in surveillance programs. However, little is known about their risk of high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC). We aimed to determine the incidence of HGD and EAC in patients with irregular Z line with intestinal metaplasia...

Barrett esophagus (BE) is the only identifiable premalignant condition for esophageal adenocarcinoma (EAC), a cancer associated with a poor 5-year survival rate. The stepwise pathologic progression of BE to invasive cancer provides an opportunity to halt progression and potentially decrease incidence and ultimately the morbidity and mortality related to this lethal cancer. Endoscopic eradication therapy (EET) in patients at increased risk of progression to invasive EAC (intramucosal EAC, high-grade dysplasia, and low-grade dysplasia) is a practice that is endorsed by multiple societies and has replaced esophagectomy as the standard of care for these patients...

BACKGROUND: Neoadjuvant chemotherapy is a standard of care for patients with adenocarcinoma of the esophagus and stomach in Europe, but still only 20-40 % respond to therapy and the critical issue; how to treat nonresponding patients is still unclear. So far, there is no randomized trial evaluating the impact of early termination of neoadjuvant chemotherapy and immediate tumor resection in nonresponding patients with locally advanced gastroesophageal cancer on postoperative outcome. With this exploratory pilot trial, we want to get first estimates about the effect of discontinuation of chemotherapy with the aim to plan and conduct a further definitive trial...

BACKGROUND: Cancers are heterogeneous comprising of distinct tumor subtypes. Therefore, presenting the burden of cancer in the population and trends over time by these tumor subtypes is important to identify patterns and differences in the occurrence of these subtypes, especially to generalize findings to the US general population. METHODS: Using SEER cancer registry data, we present incidence rates according to subtypes for diagnosis years (1992-2013) among men and women for five major cancer sites: breast (female only), esophagus, kidney and renal pelvis, lung and bronchus, and thyroid...

BACKGROUND & AIMS: The Surveillance versus RadioFrequency ablation (SURF)-trial randomized 136 patients with Barrett's esophagus (BE) containing low-grade dysplasia (LGD), to receive radiofrequency ablation (ablation, n=68) or endoscopic surveillance (control, n=68). Ablation reduced the risk of neoplastic progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) by 25% over 3 years (1.5% for ablation vs 26.5% for control). We performed a cost-effectiveness analysis from a provider perspective alongside this trial...
