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...

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...

NKX3.1 is a transcription factor used to identify prostatic adenocarcinomas. We describe novel functionality for NKX3.1 compared with Grocott and periodic acid-Schiff-diastase (PASD) on esophageal biopsies. We identified esophageal biopsies on the basis of the search term "candida" from March 28, 2012 to December 27, 2013. Of 85 cases for which 3 stains were available and at least 1 stain was positive for fungus consistent with Candida, 83 cases stained as positive with NKX3.1, compared with 79 with PASD and 75 with Grocott...

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...

Esophageal cancer as the sixth common cause of cancer death in the world consists of different histological types with various incidence patterns. Among them, esophageal adenocarcinoma and esophageal squamous cell carcinoma are the most prevalent types which also have different causality, cell of origin and risk factors. Since epidemiological studies have announced consumption of hot substances as one of the major risk factors for squamous cell carcinoma, evaluating the effect of this external stress on esophagus cells seems desirable...

BACKGROUND: Tenascin-C and fibronectin are adhesive glycoproteins modulating the structure of the extracellular matrix and cellular functions. Their expression and function in esophageal adenocarcinoma is poorly known. The aim of this study was to evaluate the expression of tenascin-C and fibronectin in esophageal adenocarcinoma and its precursor stages. RESULTS: Stromal tenascin-C and fibronectin expression were found in all evaluated lesion types. Expression of both molecules increased from gastric metaplasia towards adenocarcinoma (p<0...

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...

We have recently gained unprecedented insight into genetic factors that determine risk for Barrett's esophagus (BE) and progression to esophageal adenocarcinoma (EA). Next-generation sequencing technologies have allowed us to identify somatic mutations that initiate BE and track genetic changes during development of tumors and invasive cancer. These technologies led to identification of mechanisms of tumorigenesis that challenge the current multistep model of progression to EA. Newer, cost-effective technologies create opportunities to rapidly translate the analysis of DNA into tools that can identify patients with BE at high risk for cancer, detect dysplastic lesions at earlier stages, and uncover mechanisms of carcinogenesis...

Colorectal adenocarcinoma (CRC) is a common tumor with high mortality rates. Interestingly, CRC was found to be colonized by the oral anaerobic bacteria Fusobacterium nucleatum, which accelerates tumor progression and enables immune evasion. The CRC-specific colonization by fusobacteria is mediated through the recognition of tumor displayed Gal-GalNAc moieties by the fusobacterial Fap2 Gal-GalNAc lectin. Here, we show high Gal-GalNAc levels in additional adenocarcinomas including those found in the stomach, prostate, ovary, colon, uterus, pancreas, breast, lung, and esophagus...

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%. Regarding cases with adenocarcinoma within IP, some experts recommend to routinely obtain biopsies from IP for histopathology. Another concern is the reported relation to Barrett's esophagus. The objectives of the study were to prospectively determine the prevalence of IP and of preneoplasia within IP, and to investigate the association between IP and Barrett's esophagus...

BACKGROUND: Mucins are heavily glycosylated glycoproteins, synthesized by mucosal surfaces and have an important role in healthy state and malignant diseases. Change in mucins synthesis or secretion may be primary event or secondary to inflammation or carcinogenesis. AIM: The aim of this study is to assess the current knowledge about mucin expression in esophageal lesions, and to establish a role for different mucin expressions as prognostic markers. METHOD: English Medical literature searches were conducted for "mucin" and "esophagus...
