Esophageal adenocarcinoma (EAC) develops in an inflammatory microenvironment with reduced microbial diversity, but mechanisms for these influences remain poorly characterized. We hypothesized that mutations targeting the Toll-like receptor (TLR) pathway could disrupt innate immune signaling and promote a microenvironment that favors tumorigenesis. Through interrogating whole genome sequencing data from 171 EAC patients, we showed that non-synonymous mutations collectively affect the TLR pathway in 25/171 (14...

We report a 34-year-old man referred because of increasing dysphagia secondary to goiter. Thyroid scintigraphy and SPECT/CT images helped to recognize an unsuspected esophageal dilation due to a poorly differentiated adenocarcinoma arising at the lower end of the esophagus. Further examinations are mandatory when abnormal activities are observed during thyroid scintigraphy.

Synchronous gastric tumors, and, especially the presence of an adenocarcinoma and gastrointestinal stromal tumors, are less frequent. We present the case of a 75-year-old patient, with no gastrointestinal pathology in the medical history, who was admitted for marked asthenia, nausea, coffee grounds vomiting, inappetence, dizziness, weight loss and periodical epigastralgias. The clinical and imagistic examinations highlighted an ulcerative, infiltrative, bleeding tumor formation, present on the anterior side and subcardially on the small curvature...

REVIEW
Zhaohui Jin, Harry H Yoon
Antiangiogenesis therapy is one of only 2 biologically targeted approaches shown to improve overall survival over standard of care in advanced adenocarcinoma of the stomach or gastroesophageal junction (GEJ). Therapeutic targeting of vascular endothelial growth factor receptor 2 improves overall survival in patients with previously treated advanced gastric/GEJ adenocarcinoma. No antiangiogenesis therapy has demonstrated an overall survival benefit in patients with chemo-naïve or resectable esophagogastric cancer or in patients whose tumors arise from the esophagus...

Barrett esophagus (BE) is a precursor lesion for esophageal adenocarcinoma (EAC). Developments in imaging and molecular markers, and endoscopic eradication therapy, are available to curb the increase of EAC. Endoscopic surveillance is recommended, despite lack of data. The cancer risk gets progressively downgraded, raising questions about the understanding of risk factors and molecular biology involved. Recent data point to at least 2 carcinogenic pathways operating in EAC. The use of p53 overexpression and high-risk human papillomavirus may represent the best chance to detect progressors...

Mounting evidence has demonstrated that Bit1 has been investigated as an etiological factor for certain cancers, including esophageal squamous cell carcinoma reported in our previous study, but data regarding possible roles of Bit1 in esophageal squamous cell carcinoma and esophageal adenocarcinoma remain to be elucidated. The purpose of this study was to examine whether Bit1 can be a novel diagnostic marker for the patients with esophageal squamous cell carcinoma and esophageal adenocarcinoma. The results revealed that Bit1 level in esophageal squamous cell carcinoma was significantly higher than that in esophageal adenocarcinoma tissues ( p < 0...

Gastroesophageal reflux disease-related diseases, such as Barrett's esophagus and adenocarcinoma of the esophagogastric junction (AEGJ), are believed to occur less frequently in Asia than in Western countries. However, the number of reported cases is increasing, yet little is known regarding the epidemiology of AEGJ in Japan. The primary study aim is to investigate the clinicoepidemiological characteristics of AEGJ. The secondary aim is to identify factors associated with it. In the 6.5 years between January 2008 and June 2014, we reviewed 88,199 esophagogastroduodenoscopy (EGD) reports and associated medical records (Study 1)...

Barrett's esophagus (BE) is a premalignant condition associated with the development of esophageal adenocarcinoma (EAC). Despite the low risk of progression to EAC, evidence highlights the notably poor survival rates of this malignancy. The mainstay form of diagnosis of BE is endoscopy and biopsy sampling. However, research emphasizes limitations with regards to the histological detection of BE and associated dysplasia. The aim of this study is to evaluate the clinical significance of CEACAM6 as a potential biomarker for the diagnosis of BE and beyond...

BACKGROUND: Endoscopic management of Barrett's esophagus (BE) depends on the histological stage of BE and includes the following: follow up, endotherapy with thermal ablation, and piecemeal or monobloc endoscopic resection (ER). We know that biopsies are unreliable in 20-75% of cases. The aim of our study was to evaluate the efficiency of probe confocal laser endomicroscopy (pCLE) in the diagnosis of the histological stage of BE, compared with the final histological results after ER. METHODS: This retrospective study was based on a prospective registry of patients referred for management of BE-associated dysplasia...

BACKGROUND: Patients with resectable esophageal cancer (rEC) are managed with either concurrent chemoradiotherapy followed by surgery (CRSx) or concurrent chemoradiotherapy alone (cCR). To the authors' knowledge, there is insufficient evidence comparing the overall survival of patients treated with these 2 options. METHODS: The National Cancer Data Base was queried for rEC cases diagnosed from 2003 through 2011. Patients with previous cancers, cervical rEC, clinical stage T1N0 disease, or metastasis were excluded...

BACKGROUND AND AIMS: Data on the economic impact associated with screening for Barrett's esophagus (BE) are limited. As part of a comparative effectiveness randomized trial of unsedated transnasal endoscopy (uTNE) and sedated endoscopy (sEGD), we assessed costs associated with BE screening. METHODS: Patients were randomly allocated to 3 techniques: sEGD or uTNE in a hospital setting (huTNE) versus uTNE in a mobile research van (muTNE). Patients were called 1 and 30 days after screening to assess loss of work (due to the screening procedure) and medical care sought after procedure...

REVIEW
Rhonda Frances Souza
Reflux esophagitis damages the squamous epithelium that normally lines the esophagus, and promotes replacement of the damaged squamous lining by the intestinal metaplasia of Barrett's esophagus, the precursor of esophageal adenocarcinoma. Therefore, to prevent the development of Barrett's metaplasia and esophageal adenocarcinoma, the pathogenesis of reflux esophagitis must be understood. We have reported that reflux esophagitis, both in a rat model and in humans, develops as a cytokine-mediated inflammatory injury (i...

Esophageal cancer is a male-dominant aggressive malignancy and a leading cause of cancer-related mortality worldwide. Squamous cell carcinoma and adenocarcinoma are the two predominant histological subtypes with varying geographical and racial distribution. Globally, squamous cell carcinoma remains the most common histological type. In Western countries, however, adenocarcinoma has become the leading histological subtype, corresponding to a rise in the incidence of obesity, gastro-esophageal reflux disease and Barrett's esophagus...

Esophageal cancer is a serious malignancy with high mortality. The two common distinctive pathologic subtypes of esophageal cancer are squamous cell carcinoma and adenocarcinoma. These differ with regards to etiology, ethnic distribution, pathogenesis, and location in the esophagus. The precursor lesions are also unique to each subtype. Squamous cell carcinoma is more common in East Asia, is linked to smoking and tobacco use, more commonly involves the middle esophagus, and the precursor lesion is squamous dysplasia...

Mortality from esophageal cancer remains high despite advances in medical therapy. Although the incidence of squamous cell carcinoma of the esophagus remains unchanged, the incidence of the esophageal adenocarcinoma has increased over time. Gastroesophageal reflux disease (GERD and obesity are contributing factors to the development of Barrett's esophagus and subsequent development of adenocarcinoma. Early recognition of the disease can lead to resection of esophageal cancer prior to the development of lymphovascular invasion...

Barrett's esophagus (BE) is a premalignant condition that increases the risk of esophageal adenocarcinoma (EAC). Significantly more common in the Western world, risk factors include increased age, male sex, white race, gastro-esophageal reflux disease (GERD), central obesity, and cigarette smoking. The rates of progression to cancer depend on the grade of Barrett's dysplasia. Screening for BE is recommended in patients with GERD and additional risk factors. Endoscopic surveillance of patients with BE likely improves overall outcomes...

The incidence of Barrett's esophagus (BE) in the Western world has increased over the last decades. BE is considered a premalignant lesion that can progress to esophageal adenocarcinoma (EAC), a highly aggressive malignancy with poor survival rates. The close association between BE and EAC highlights the need for an early diagnosis in order to improve survival and outcomes in this group of patients. Although the evidence for BE screening with conventional endoscopy is controversial and limited by cost-effectiveness studies, screening can be suggested in patients with chronic gastroesophageal reflux disease (GERD) and two or more risk factors for EAC...
