The incidence of esophageal adenocarcinoma (EAC) is rising rapidly, and early detection within the precursor state of Barrett's esophagus (BE) is challenged by flat premalignant lesions that are difficult detect with conventional endoscopic surveillance. Overexpression of cell surface fibroblast growth factor receptor 2 (FGFR2) is an early event in progression of BE to EAC, and is a promising imaging target. We used phage display to identify the peptide SRRPASFRTARE that binds specifically to the extracellular domain of FGFR2...

Background: Obesity and diabetes mellitus are associated with lifestyle-related carcinogenesis. They are also risk factors of esophageal adenocarcinoma, but there are only a few reports on association between obesity/diabetes and development of squamous cell carcinoma in the oral cavity and esophagus. In this study, we therefore aimed to determine whether obesity and diabetes affect oral and esophageal carcinogenesis using model mice of obesity and diabetes, the Tsumura Suzuki obese diabetes (TSOD) and Tsumura Suzuki non-obesity (TSNO) control mice, which were treated with 4-nitroquinoline 1-oxide (4-NQO) to produce tongue and esophageal carcinomas...

The vast majority of esophageal adenocarcinoma cases are sporadic and caused by somatic mutations. However, over the last decades several families have been identified with clustering of Barrett's esophagus and esophageal adenocarcinoma. This observation suggests that one or more hereditary factors may play a role in the initiation of Barrett's esophagus and esophageal adenocarcinoma in these families. A Dutch family with clustering of Barrett's esophagus and esophageal adenocarcinoma was identified. Normal DNA obtained from the proband diagnosed with Barrett's esophagus was analyzed with SNP array and exome sequencing...

Gastroesophageal reflux disease (GERD) is a gastrointestinal motility disorder that results from the reflux of stomach contents into the esophagus or oral cavity resulting in symptoms or complications. The typical symptoms of GERD are heartburn and regurgitation of gastric contents into the oropharynx. GERD affects quality of life and may cause erosive esophagitis, esophageal strictures, and Barrett esophagus, a precursor to esophageal adenocarcinoma. GERD is a clinical diagnosis and is most effectively treated with proton-pump inhibitors (PPIs)...

Esophageal cancer, the sixth most common cause of cancer globally, is characterized by the development of early systemic metastatic disease. Adenocarcinoma of the esophagus and gastroesophageal junction (GEJ) is more common in the West. Preoperative chemotherapy or chemoradiotherapy is employed for locally advanced disease with contemporary studies suggesting higher rates of curative resection and reduced rates of local recurrence with the combination of chemotherapy and radiation therapy given prior to surgery...

Esophageal cancer is the 8th most common cancer worldwide and the 6th most common cause of cancer-related death. Its two main subtypes, esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), have varying incidences globally, but recent decades have seen a demonstrated rise of EAC in Western countries whereas ESCC remains highly prevalent in Eastern Africa, Central Asia, and China. Screening interventions have focused on using endoscopy to identify Barrett's esophagus (BE) as a precursor to EAC, and squamous cell dysplasia prior to onset of ESCC...

For adenocarcinoma of the gastroesophageal junction (GEJ) the classification of Siewert with its three subtypes is well established as a practical approach to surgical treatment. Transthoracic esophagectomy with gastric tube formation is generally accepted as the surgical standard for adenocarcinoma of the distal esophagus (GEJ type I). Intrathoracic esophagogastrostomy has become the most frequently used anastomotic technique (Ivor Lewis esophagectomy). Both the abdominal and thoracic part can be safely performed with a minimally invasive access...

BACKGROUND: The efficacy of carboplatin-paclitaxel in the trimodality setting was demonstrated in the cross trial. Because of better tolerance, that regimen has been adopted as an alternative for patients receiving definitive chemoradiation (dcrt). The purpose of our study was to compare outcomes in patients with localized esophageal and gastroesophageal junction (gej) cancer who received dcrt using either platinum-5-fluorouracil (5fu) or carboplatin-paclitaxel. METHODS: Medical records and outcomes for all patients diagnosed with localized carcinoma of the esophagus and gej at our centre between 2008 and 2015 were reviewed...

Several markers of pancreatobiliary lineage have been described in the literature. However, none have demonstrated sufficient specificity and sensitivity to warrant diagnostic use. We evaluated the utility of T-complex-associated-testis-expressed 3 (TCTE3) as a pancreatobiliary marker. A set of 247 adenocarcinomas from the gastrointestinal (GI) tract was identified including 18 from the gastroesophageal junction (GEJ), 29 stomach, 17 ampullary, 62 pancreatic, and 16 common bile duct and gallbladder (CBD/GB), 13 non-ampullary small intestine, 32 colon, and 24 rectum...

Juan A Muñoz-Largacha, Virginia R Litle
The prevalence of gastroesophageal reflux disease as well as the incidence of Barrett's esophagus (BE) has increased in the Western world over the last decades. The chronic reflux of gastric secretions injuries the esophageal mucosa and triggers cellular and molecular changes inducing the transformation of the normal squamous mucosa into columnar metaplastic epithelium. BE is a premalignant condition that can progress to low-grade dysplasia, high-grade dysplasia and ultimately esophageal adenocarcinoma. An early diagnosis of dysplastic changes and the adoption of appropriate therapeutic approaches are essential to improve patient outcomes and survival...

Totally endoscopic two stage (laparoscopic and VATS) esophagectomy for carcinoma of the esophagus is a well-established procedure. There are currently many methods to perform the intrathoracic esophagogastric anastomosis by VATS. This article describes a totally hand sewn VATS intrathoracic esophagogastric anastomosis technique in a 64-year-old female with a T2N0M0 adenocarcinoma of the lower third of the esophagus.

BACKGROUND: Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) are far more prevalent in European Americans than in African Americans. Hypothesizing that this racial disparity in prevalence might represent a genetic susceptibility, we used an admixture mapping approach to interrogate disease association with genomic differences between European and African ancestry. METHODS: Formalin fixed paraffin embedded samples were identified from 54 African Americans with BE or EAC through review of surgical pathology databases at participating Barrett's Esophagus Translational Research Network (BETRNet) institutions...

Barrett's esophagus (BE) is associated with an increased risk of developing esophageal adenocarcinoma. Despite the low absolute risk of neoplastic progression of BE, probability increases with the diagnosis of dysplasia. For this reason, BE patients undergo an endoscopy-based surveillance that is, however, burdensome for patients, subject to inter-observer subjectivity, and expensive for national health systems. Thus, less invasive and low-cost diagnostic tools are needed. This study is aimed at finding a simple and reliable method to detect the circulating cell-free DNA (cfDNA) in BE patients as evidence of the molecular instability that accompanies BE carcinogenesis...

BACKGROUND: Dyspepsia is a symptom complex rather than a specific disease entity. It can be caused by both organic and functional gastrointestinal (GI) disorders. Gastroesophageal reflux disease (GORD) though a common digestive disorder worldwide is scarcely reported in Nigeria. The aim of this study is to determine the pattern of presentation of GORD among patients with dyspepsia. METHODS: One hundred and seventy dyspeptic patients were recruited consecutively as they were referred to the Gastroenterology Unit of Aminu Kano Teaching Hospital for upper GI endoscopy...

PURPOSE/OBJECTIVE: Local treatment options for patients with in-field non-small cell lung cancer (NSCLC) recurrence following conventionally fractionated external beam radiation therapy (CF-EBRT) are limited. Stereotactic body radiation therapy (SBRT) is a promising modality to achieve reasonable local control, although toxicity remains a concern. MATERIALS/METHODS: Patients previously treated with high-dose CF-EBRT (≥59.4 Gy, ≤3 Gy/fraction) for non-metastatic NSCLC who underwent salvage SBRT for localized ultra-central in-field recurrence were included in this analysis...

BACKGROUND: Recent studies have identified age-related changes in DNA methylation patterns in normal and cancer tissues in a process that is called epigenetic drift. However, the evolving patterns, functional consequences, and dynamics of epigenetic drift during carcinogenesis remain largely unexplored. Here we analyze the evolution of epigenetic drift patterns during progression from normal squamous esophagus tissue to Barrett's esophagus (BE) to esophageal adenocarcinoma (EAC) using 173 tissue samples from 100 (nonfamilial) BE patients, along with publically available datasets including The Cancer Genome Atlas (TCGA)...

The increasing incidence of adenocarcinoma of the lower esophagus and cardia arising in Barrett's metaplastic epithelium continues to be of great concern because medical and surgical efforts to reverse the process have been disappointing. A potential answer to the problem is removal of the metaplastic epithelium. Modern technology has introduced physical and chemical modalities which facilitate ablation of the neo-epithelium endoscopically. These techniques have been used in several centers, and preliminary results are encouraging...
