Background & Aims: Esophageal Cancer is the sixth fatal cancer in the world. Squamous and adenocarcinoma account for 95% of esophageal cancer. The expression of EGFR has a role in the pathophysiology of epidermal-based malignancies such as esophageal cancer. EGFR is also an important criterion in the evaluation of disease staging and prognosis. The aim of this study was to survey the prevalence...

PURPOSE The RAS association domain family 1A (RASSF1A) gene, a candidate tumor suppressor gene, is frequently inactivated by hypermethylation of its promoter region in several human cancers. The aim of this study was to evaluate the promoter methylation status of the RASSF1A in esophageal squamous cell carcinoma. EXPERIMENTAL DESIGN We analyzed the methylation status of RASSF1A promoter by me...

Mammalian esophagus exhibits a remarkable change in epithelial structure during the transition from embryo to adult. However, the molecular mechanisms of esophageal epithelial development are not well understood. Zebrafish (Danio rerio), a common model organism for vertebrate development and gene function, has not previously been characterized as a model system for esophageal epithelial develop...

Villin is an actin-binding cytoskeletal protein required for brush-border formation in the normal small intestinal and renal proximal tubule epithelium. Villin is a marker of cell differentiation in small intestinal and renal cell lineages, and recent studies have shown villin to be highly expressed in 100% of intestinal-type Barrett's metaplasias. This epithelium is the single greatest risk fa...

Subtotal esophagectomy with extended lymph node dissection is a standard procedure for thoracic esophageal squamous cell carcinoma. Three-field lymphadenectomy, including neck dissection, is a standard type of lymph node dissection for complete clearance of tumor cells. Based on various series of analyses for lymph node metastases, the appropriate indication for neck dissection has been clarifi...

Synchronous squamous cell esophageal and squamous cell gastric cancer is a rare duo. A 48-year-old male visited our hospital with a history of dysphagia and melena and was diagnosed with synchronous esophageal and gastric cancer by endoscopy and histopathology. We report a case of a synchronous cancer that was successfully treated by chemotherapy followed by surgery. We also discuss the hypothe...

Early esophageal squamous cell carcinoma detected by esophageal iodine staining can be easily treated by endoscopic mucosectomy, and identifying its predictors is important in better selecting candidates to screen for this high-mortality cancer. The common etiologies of elevated mean corpuscular volume (MCV) and esophageal cancer, including folate deficiency, smoking, drinking and high acetalde...

BACKGROUND A malignant tracheoesophageal/bronchoesophageal fistula (TEF) is a life-threatening complication of esophageal squamous cell carcinoma. A feeding gastrostomy/jejunostomy had been the most common treatment method for patients with TEF before the era of stenting. The aim of this retrospective study is to compare the prognosis of esophageal squamous cell carcinoma patients with TEF trea...

BACKGROUND/AIMS Endoscopic treatment has been broadly applied to superficial esophageal neoplasms. Endoscopic submucosal dissection (ESD) allows for high rates of en bloc resection, precise histological assessment, and low rates of local recurrence. The aim of this study was to evaluate the outcomes of ESD for superficial esophageal neoplasms. METHODS We retrospectively reviewed 36 esophageal...

stenosis, more than 10 cm of the esophagogastric junction. The biopsy diagnosed esophageal squamous carcinoma and gastric adenocarcinoma. CT of chest, abdomen and pelvis dismissed pleural effusion or chest lymphnodes. Showed concentric thickening of the lower third of the esophagus, in gastroesophageal junction, antrum and lymph node along the lesser gastric curvature . Liver was normal in size...
