Purpose: Patients with advanced or metastatic adenocarcinoma of the stomach or esophagogastric junction for whom trastuzumab therapy is being considered, assessment for tumor human epidermal growth factor receptor-2 (HER2) status is necessary. Can the HER2 status and Lauren classification of the biopsy sample truly represent the HER2 status in the gastric cancer? Methods: Formalin-fixed, paraffin-embedded sections of 116 pair surgically resected and biopsy specimens as well as 80 pair primary and metastatic lesions of gastric cancer patients were analyzed...

Background: To detect a novel treatment target for adenocarcinoma of the esophagogastric junction (AEG), we tested whether C-terminal tensin-like (CTEN), a member of the tensin gene family and frequently overexpressed in various cancers, acts as a cancer-promoting gene through overexpression in AEG. Materials and Methods: We analyzed 5 gastric adenocarcinoma (GC) cell lines and 104 primary AEG tumors curatively resected in our hospital between 2000 and 2010. Results: CTEN overexpression was detected in GC cell lines (2/5 cell lines; 40%) and primary AEG tumor samples (35/104 cases; 34%)...

BACKGROUND: Laparoscopic wedge resection (LWR) is used to treat gastric submucosal tumors (SMTs). However, LWR can injure the cardia if tumors are near the esophagogastric junction (EGJ), resulting in gastric stenosis. This study's purpose was to summarize our experience with endoscope-assisted LWR for gastric SMTs within 3 cm of the EGJ and to verify the procedure's feasibility and safety. METHODS: Data from 91 consecutive patients with gastric SMTs within 3 cm of the EGJ who underwent endoscope-assisted LWR at our hospital from 2007 to 2017 were obtained from a prospectively maintained database...

The poor prognosis for patients with esophagogastric cancers (EGC) requires the development of newer more effective therapies to further improve the treatment outcomes for this disease. Immunotherapy is a novel treatment strategy that is dramatically changing the treatment landscape for several types of cancers. Cytotoxic T lymphocyte antigen-4 (CTLA-4) and programmed death the programmed death (PD)-1/PD-ligand are essential immune checkpoint inhibitors that suppress T cell activation. Targeting of these immune checkpoints with monoclonal antibodies has shown clinical efficacy in several solid tumors which has led to their approval and use in routine clinical practice...

As one-half of patients with esophagogastric cancer (EGC) present with metastatic disease and the majority of patients with locally advanced disease will eventually develop metastatic disease despite multimodality therapy, most patients will receive palliative chemotherapy at some point. The reference first-line regimen consists of a fluoropyrimidine/platinum combination, which is the standard in East Asia, where this disease is endemic. Options include infusional 5-fluorouracil (5-FU), capecitabine, S-1 and other oral 5-FU pro-drugs and cisplatin or oxaliplatin...

The poor prognosis for patients with esophagogastric cancers (EGC) has resulted in an increased focus on the use of targeted agents in this disease. Targets include epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), Her2, mammalian target of rapamycin (mTOR), MET, poly (ADP-ribose) polymerase (PARP) and claudin 18.2 (CLDN18.2). Trastuzumab, an anti-Her2 antibody, was approved by the U.S. FDA in 2010 as first-line therapy in combination with chemotherapy for Her2-positive disease...

The incidence of esophagogastric cancer is rapidly rising but only a minority of patients derive durable benefit from current therapies. Chemotherapy as well as anti-HER2 and PD-1 antibodies are standard treatments. To identify predictive biomarkers of drug sensitivity and mechanisms of resistance, we implemented prospective tumor sequencing of metastatic esophagogastric cancer patients. There was no association between HRD defects and response to platinum-based chemotherapy. Patients with MSI-H tumors were intrinsically resistant to chemotherapy but more likely to achieve durable responses to immunotherapy...

Brain metastases originating from esophageal or gastric cancer are rare, accounting for 2.1-3.3% of all brain tumors registered in Japan. There are no established therapeutic measures for brain metastases, which accordingly have a poor prognosis. We present here a patient who survived for 5 years after surgery and gamma knife treatment of a cerebellar metastasis from esophagogastric adenocarcinoma. The primary gastric cancer was treated by laparotomy with total gastrectomy, splenectomy, and D2 lymphadenectomy...

INTRODUCTION: We debate whether or not to approach from right thorax for the left chylothorax after esophagectomy. PRESENTATION OF CASE: A 50s-year-old female underwent right-sided thoracoscopic esophagectomy with three-field lymphadenectomy for esophageal carcinoma (type 0-IIa, 3.4×2.2cm, T1bN0M0, Stage IA), followed by reconstruction with esophagogastric anastomosis through the posterior mediastinum. The thoracic duct was excised and ligated. The left thoracic drainage increased to 2115mL/day on the fifth postoperative day...

BACKGROUND: Increased esophagogastric junction (EGJ) distensibility is thought to contribute to gastroesophageal reflux disease (GERD). Using the functional lumen imaging probe (FLIP), we aimed to assess the esophageal response to distension among patients undergoing esophageal pH monitoring. METHODS: 25 patients (ages 22-73; 13 females) who underwent ambulatory wireless esophageal pH testing while off proton-pump inhibitors were evaluated with FLIP during sedated upper endoscopy...

AIM: To determine whether the presence of columnar-lined esophagus (CLE) is associated with the presence of esophageal varices (EVs) in male Japanese alcoholics. METHODS: The subjects were 1614 Japanese alcohol-dependent men (≥ 40 years of age) who had undergone upper gastrointestinal endoscopic screening. Digitalized records of high-quality endoscopic images that included the squamocolumnar junction and esophagogastric junction were retrospectively jointly reviewed by four expert endoscopists for the purpose of diagnosing CLE...

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.

INTRODUCTION: Anastomotic leakage after gastrointestinal surgery is a significant cause of morbidity and mortality. Esophagogastric and colorectal anastomoses are vulnerable to leakage. Extended knowledge of growth factors and their receptors is needed to understand anatomic healing. METHODS: The expression pattern of vascular growth factor receptor (VEGFR1-3), epidermal growth factor receptor (EGFR), platelet-derived growth factor receptor (PDGFRα/β) and keratinocyte growth factor receptor (KGFR) were analyzed by semiquantitative-PCR in the rat intestinal tract and in esophagogastric anastomosis 5d after surgery...

BACKGROUND: Laparoscopic surgery for patients with portal hypertension is considered to be contraindicated because of the high risk of massive intraoperative hemorrhaging. However, recent reports have shown hand-assisted laparoscopic surgery for devascularization and splenectomy to be a safe and effective method of treating esophagogastric varices with portal hypertension. The aim of this study is to evaluate the efficacy of hand-assisted laparoscopic devascularization and splenectomy (HALS Hassab's procedure) for the treatment of esophagogastric varices with portal hypertension...

BACKGROUND: Synchronous liver metastases (LM) from gastric (GC) or esophagogastric junction (EGJ) adenocarcinoma are a rare events. Several trials have evaluated the role of liver surgery in this setting, but the impact of preoperative therapy remains undetermined. METHODS: Patients with synchronous LM from GC/EGJ adenocarcinoma who achieved disease control after induction chemotherapy (ICT) and were subsequently scheduled to chemoradiotherapy (CRT) to the primary tumor and surgery assessment were retrospectively analyzed...

Almost 10% of patients with Crest syndrome associated with severe gastroesophageal reflux and 5-10% of patients with failed cardiomyotomy for achalasia present with cardial or distal esophageal organic stricture. Some of these cases are poor risk patients for surgery and therefore the surgeon must offer a safe procedure with low morbimortality, keeping in mind the pathophysiological motor pattern of these patients.In order to treat the stricture to improve the esophageal transit we treated patients with esophagocardioplasty associated with vagotomy-antrectomy and Roux-en-Y gastrojejunostomy, thereby avoiding the potential acid or biliary reflux in poor risk patients in whom esophagectomy would be a very deleterious procedure...

Here, we present a case of a 50-year-old male with a history of a Guillain-Barré-syndrome, who was referred to our clinic with recurrent esophageal candidiasis and long-standing intermittent retrosternal cramps for further evaluation. Other symptoms such as dysphagia, regurgitations and weight loss were denied, and prior repeated endoscopy was otherwise unremarkable. Using high resolution impedance manometry, we could demonstrate a panesophageal pressure increase on water swallows and complete aperistalsis of the tubular esophagus, indicating achalasia type II...

A novel molecular classification of gastric cancer by the Asian Cancer Research Group (ACRG) is a potential advance in diagnosis and treatment, and it helps to determine prognosis. The use of immunohistochemistry (IHC) rather than gene expression analysis to determine tumor subtypes was evaluated with the aim of determining the feasibility of using the ACRG molecular classification. A total of 69 esophagogastric junction (EGJ) carcinomas were classified as microsatellite instable (MSI, 17.40%, 12 of 69), microsatellite stable with markers of epithelial-to-mesenchymal transition (MSS/EMT, 18...

BACKGROUND: Integrated relaxation pressure (IRP) is a key metric for diagnosing esophagogastric junction outflow obstruction (EGJOO). However, its normal value might be different according to the manufacturer of high-resolution manometry (HRM). This study aimed to investigate optimal value of IRP for diagnosing EGJOO in Sandhill HRM and to find clinicomanometric variables to segregate clinically relevant EGJOO. METHODS: We analyzed 262 consecutive subjects who underwent HRM between June 2011 and December 2016 showing elevated median IRP (> 15 mm Hg) but did not satisfy criteria for achalasia...
