INTRODUCTION: Cigarette smoking and alcohol consumption have a well-known effect on the development of upper aerodigestive tract carcinomas, but such a role for opium is questionable. This study was designed to assess the correlation between opium inhalation and cancer of the larynx and upper esophagus. MATERIALS AND METHODS: Fifty eight patients with laryngeal cancer, ninety eight patients with upper esophageal cancer and twenty seven healthy individuals with no evidence of head and neck or esophageal malignancies were selected from Otolaryngology and Radiation Oncology Department of Mashhad University of Medical Sciences...

Bile acid reflux in the esophagus plays an important role in the carcinogenesis of esophageal adenocarcinoma (EAC). The G-protein coupled bile acid receptor (TGR5) has been associated with the development of gastrointestinal cancer. However, little is known regarding the role of TGR5 in esophageal carcinoma and precancerous lesions. We analyzed genomic DNA from 116 EACs for copy number aberrations via Affymetrix SNP6.0 microarrays. The TGR5 gene locus was amplified in 12.7% (14/116) of the EACs. The TGR5 protein expression was also assessed using immunohistochemistry from tissue microarrays, including Barrett's esophagus (BE), low-(LGD) and high-grade dysplasia (HGD), columnar cell metaplasia (CM), squamous epithelium (SE), EAC and squamous cell carcinoma...

INTRODUCTION: Barrett's esophagus (BE), which develops as a result of gastroesophageal reflux disease, is a preneoplastic condition for esophageal adenocarcinoma (EAC). A new hypothesis suggests that cancer is a disease of stem cells, however, their expression and pathways in BE - EAC sequence are not fully elucidated yet. AIMS: We used a panel of putative cancer stem cells markers to identify stem cells in consecutive steps of BE-related cancer progression. METHODS: Immunohistochemistry was performed on formalin-fixed, paraffin-embedded blocks from 58 patients with normal cardiac mucosa (n=5), BE (n=14), early EAC (pT1) from mucosal resection (n=17) and advanced EAC (pT1-T4) from postoperative specimens (n=22)...

INTRODUCTION: Cancer of the esophagus is among the leading cause of cancer deaths in Punjab, India. Patients generally present with dysphagia as their first symptom and more often they have advanced disease at the time of presentation to a tertiary care centre. Palliative procedures have important roles in this setting. Stenting is the best option to palliate the symptoms of dysphagia, from which patient is suffering the most. AIM: To know the success rate, early and long term complications and mortality in esophageal stenting, when it was done in malignant esophageal stricture patients...

BACKGROUND: Monocarboxylate transporters (MCTs) are cell membrane proteins which transport pyruvate, lactate and ketone bodies across the plasma membrane. MCTs are activated in various cancers, but their expression in esophageal adenocarcinoma is not known. The present study was conducted to elucidate the expression of MCTs in esophageal adenocarcinoma and its precursor lesions. RESULTS: Cytoplasmic MCT1, MCT4 and MTCO1 expression linearly increased from normal epithelium to Barrett's mucosa to dysplasia and cancer...

BACKGROUND: Controversy remains regarding biliary reflux after one-anastomosis gastric bypass (OAGB). The aim of this "pilot" study was to analyze biliary reflux and its potential long-term consequences on esogastric mucosae in OAGB-operated rats. METHODS: Diet-induced obese rats were subjected to OAGB (n = 10) or sham (n = 4) surgery and followed up for 16 weeks. Evolution of weight and glucose tolerance was analyzed. Bile acid concentration measurement, histological and qRT-PCR analysis were performed in the esogastric segments...

Vitamin D has been widely used as a dietary supplement for the prevention and treatment of bone disorders. Epidemiological and preclinical studies demonstrated the anticancer action of vitamin D in a variety of cancers including those in the gastrointestinal (GI) tract. In these studies the inhibitory action of vitamin D on cancer stem cells (CSCs) has been a focus and is also an important subject to revolutionize the therapeutic potential of vitamin D on cancer treatment. Here, we summarize the involvement of CSC markers and factors and also their signaling pathways in the development of cancers in the esophagus, stomach, colon, pancreas and also liver...

Obesity is usually associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause [e.g. non-alcoholic fatty liver diseases (NAFLD)] or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease (GERD), erosive esophagitis, Barrett's esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including NAFLD, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer...

Background. Intra-abdominal metastases of invasive lobular breast cancer (ILBC) may be insidious. We report a case of metastatic ILBC that presented with dysphagia within weeks of a negative mammogram and before the development of intra-abdominal symptoms. Case. A 70-year-old female developed esophageal dysphagia. She underwent EGD which showed a short segment of stricture of the distal esophagus without significant mucosal changes. Biopsy was unremarkable and patient underwent lower esophageal sphincter (LES) dilation...

INTRODUCTION/OBJECTIVES: Incidence of esophageal adenocarcinoma (EA), an often fatal cancer, has increased sharply over recent decades. Several important risk factors (reflux, obesity, smoking) have been identified for EA and its precursor, Barrett's esophagus (BE), but a key challenge remains identifying individuals at highest risk, since most with reflux do not develop BE, and most with BE do not progress to cancer. Metabolomics represents an emerging approach for identifying novel biomarkers associated with cancer development...

Disrupted cell polarity is a feature of epithelial cancers. The partitioning defective 3 (PAR-3) protein, a key component of the PAR complex that regulates the polarization of cells, is involved in tight junction formation at epithelial cell-cell contacts. Our previous study detected a homozygous deletion of the PAR-3 gene in esophageal squamous cell carcinoma (ESCC) cell lines and frequent copy number loss of the PAR-3 gene in primary ESCC. Here, we aimed to investigate the clinicopathological relevance of altered expression of the PAR-3 protein in primary ESCC...

BACKGROUND: Insulin-resistance and hyperinsulinemia could have a role in the growing incidence of esophageal adenocarcinoma (EAC) and its pre-cancerous lesion Barrett's Esophagus (BE). HER2 activation has also a pivotal role in EAC carcinogenesis but no data correlate these two phenomena in this disease context. AIMS: To investigate the role of hyperinsulinemia in BE-dysplasia-adenocarcinoma sequence and the possible relationship between insulin-mediated and HER2 signaling in EAC development...

REVIEW
Richard H Hunt, Mohammad Yaghoobi
The esophagus and stomach are host to their own population of bacteria, which differs in health and disease. Helicobacter pylori uniquely colonizes only gastric mucosa, but an increasing number of bacteria is now isolated from the gastric juice and gastric mucosa, including Lactobacillus. The presence of H pylori alters populations of other gastric bacteria with a marked reduction in diversity. Alterations in intragastric acidity may be the cause or the consequence of changes in the microbial populations of the stomach...

INTRODUCTION: The incidence of lymph node metastasis in the dorsal area of the thoracic aorta (DTA) is relatively low in patients with esophageal cancer. It is difficult to approach the DTA using surgical procedures, such as an open thoracotomy and thoracoscopy in the left decubitus position. CASE PRESENTATION: Case 1: A 70-year-old man with esophageal cancer underwent thoracoscopic esophagectomy with mediastinal lymph node dissection via a right thoracoscopic approach, followed by lymphadenectomy in the DTA via left thoracoscopy in the prone position...

: 222 Background: Rolapitant (VARUBI) is a selective, long-acting neurokinin-1 receptor antagonist (RA) for the prevention of CINV. Rolapitant effectively prevented CINV in phase 3 trials of patients (pts) receiving highly or moderately emetogenic chemotherapy (HEC, MEC). While MEC and HEC regimens are commonly used to treat pts with gastrointestinal and colorectal cancers (GI/CRC), very few studies have evaluated the effectiveness of a neurokinin-1 RA regimen in these pts. We assessed the incidence of CINV and efficacy of rolapitant in a subset of pts with GI/CRC...

Aims. In order to determine the indications of transoral surgery for a tumor located at the pharyngoesophageal junction, the trumpet maneuver with transnasal endoscopy was used. Its efficacy is reported here. Material and Methods. An 88-year-old woman complaining of dysphagia, diagnosed with cervical esophageal cancer, and hoping to preserve her voice and swallowing function was admitted to our hospital. Conventional endoscopy showed that the tumor had invaded the hypopharynx. When inspecting the hypopharynx and the orifice of the esophagus, we asked the patient to blow hard and puff her cheeks with her mouth closed (trumpet maneuver)...

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) for esophageal cancer often causes postoperative stricture when more than three-quarters of the circumference of the esophagus is dissected. Mesenchymal stem cells are a valuable cell source in regenerative medicine, and conditioned medium (CM) obtained from mesenchymal stem cells reportedly inhibits inflammation. In this study, we evaluated whether CM could prevent esophageal stricture after ESD. METHODS: We resected a semi-circumference of pig esophagus by ESD...
