A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.

Multiple target sites of allelic imbalance on chromosome 17 in Barrett's oesophageal cancer. (1/1038)

Twelve Barrett's adenocarcinomas have been analysed for the occurrence of allelic imbalance (LOH) on chromosome 17 using 41 microsatellite markers. This study provides evidence for 13 minimal regions of LOH, six on 17p and seven on 17q. Four of these centre in the vicinity of the known tumour suppressor genes (TSGs) TP53 (17p13.1), NFI (17q11.2), BRCA1 (17q21.1), and a putative TSG (17p13.3). The tumours all displayed relatively small regions of LOH (1-10 cM), and in several tumours extensive regions of LOH were detected. One tumour displayed only two very small regions of LOH; 17p11.2 and 17p13.1. The frequency of allelic imbalance has been calculated based on the LOH encompassing only one minimal region, and based on all the LOH observations. By both evaluations the highest LOH frequencies were found for regions II (p53), III (17p13.1 centromeric to p53), IV (17p12), V (17p11.2) and VII (NF1, 17q11.2). Our data supports the existence of multiple TSGs on chromosome 17 and challenges the view that p53 is the sole target of LOH on 17p in Barrett's adenocarcinoma.  (+info)

Differential expression of Hsp27 in normal oesophagus, Barrett's metaplasia and oesophageal adenocarcinomas. (2/1038)

The protein expression patterns of normal, metaplastic and malignant oesophageal tissues were analysed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) to identify changes associated with Barrett's metaplasia and transformation to oesophageal adenocarcinoma. Heat-shock protein 27 (Hsp27), a small heat-shock protein which is protective against cytotoxic stresses, was abundant in normal oesophagus. However, Hsp27 expression was markedly lower in Barrett's metaplasia and oesophageal adenocarcinomas. This was confirmed by immunohistochemical analysis. Hsp27 protein was most highly expressed in the upper layers of squamous epithelium and exhibited a pattern of expression that corresponded with the degree of squamous maturation. Northern and Southern analysis demonstrated Hsp27 to be regulated at the level of mRNA transcription or abundance. Normal oesophageal tissues were examined for gender differences in Hsp27 expression. Women expressed fourfold higher levels of Hsp27 mRNA, however, this difference was not appreciable in protein expression. Hsp27 protein was inducible by heat shock in Barrett's adenocarcinoma cell lines and an immortalized oesophageal epithelial cell line (HET-1A), but not by oestradiol. These results demonstrate abundant constitutive expression of the stress-response protein Hsp27 in the normal oesophagus, and suggest that low-level expression in Barrett's metaplasia may be one factor which may influence susceptibility to oesophageal adenocarcinoma development.  (+info)

Symptomatic gastroesophageal reflux as a risk factor for esophageal adenocarcinoma. (3/1038)

BACKGROUND: The causes of adenocarcinomas of the esophagus and gastric cardia are poorly understood. We conducted an epidemiologic investigation of the possible association between gastroesophageal reflux and these tumors. METHODS: We performed a nationwide, population-based, case-control study in Sweden. Case ascertainment was rapid, and all cases were classified uniformly. Information on the subjects' history of gastroesophageal reflux was collected in personal interviews. The odds ratios were calculated by logistic regression, with multivariate adjustment for potentially confounding variables. RESULTS: Of the patients interviewed, the 189 with esophageal adenocarcinoma and the 262 with adenocarcinoma of the cardia constituted 85 percent of the 529 patients in Sweden who were eligible for the study during the period from 1995 through 1997. For comparison, we interviewed 820 control subjects from the general population and 167 patients with esophageal squamous-cell carcinoma. Among persons with recurrent symptoms of reflux, as compared with persons without such symptoms, the odds ratios were 7.7 (95 percent confidence interval, 5.3 to 11.4) for esophageal adenocarcinoma and 2.0 (95 percent confidence interval, 1.4 to 2.9) for adenocarcinoma of the cardia. The more frequent, more severe, and longer-lasting the symptoms of reflux, the greater the risk. Among persons with long-standing and severe symptoms of reflux, the odds ratios were 43.5 (95 percent confidence interval, 18.3 to 103.5) for esophageal adenocarcinoma and 4.4 (95 percent confidence interval, 1.7 to 11.0) for adenocarcinoma of the cardia. The risk of esophageal squamous-cell carcinoma was not associated with reflux (odds ratio, 1.1; 95 percent confidence interval, 0.7 to 1.9). CONCLUSIONS: There is a strong and probably causal relation between gastroesophageal reflux and esophageal adenocarcinoma. The relation between reflux and adenocarcinoma of the gastric cardia is relatively weak.  (+info)

Review article: Helicobacter pylori and gastro-oesophageal reflux disease-clinical implications and management. (4/1038)

A significant proportion of patients with gastro-oesophageal reflux disease (GERD) have Helicobacter pylori infection, but it is unclear whether or not H. pylori should be treated in this clinical setting. The aim of this review was to critically assess the relationship between H. pylori and GERD and its potential implications for the management of GERD. Data for this review were gathered from the following sources up to April 1998-the biomedical database MEDLINE, a detailed review of medical journals, and a review of abstracts submitted to relevant international meetings. On average, 40% of GERD patients carry H. pylori infection, with a reported infection prevalence ranging from 16% to 88%. To date, there has been no reported controlled trial of effective H. pylori therapy in GERD. GERD has been reported to develop de novo following the cure of H. pylori in peptic ulcer disease. In the presence of H. pylori, proton pump inhibitor therapy appears to accelerate the development of atrophic corpus gastritis, a potentially precancerous condition. Conversely, proton pump inhibitor therapy seems to become less effective after cure of H. pylori. The mechanisms underlying these important contrasting phenomena are poorly understood. The relationship between H. pylori and GERD is complex, and it is difficult to give definitive guidelines on the management of H. pylori infection in GERD. Controlled trials of H. pylori therapy in GERD are urgently needed, as well as further long-term data on both the natural history of gastric histopathological changes in the H. pylori-positive GERD patient treated with proton pump inhibitors, and the impact of H. pylori status on the clinical efficacy of antisecretory therapy. Pending these data, it is perhaps advisable to advocate cure of H. pylori in young patients with proton pump inhibitor-dependent GERD who, in the absence of anti-reflux surgery, are faced with the likelihood of long-term medical therapy.  (+info)

Impact of endoscopic biopsy surveillance of Barrett's oesophagus on pathological stage and clinical outcome of Barrett's carcinoma. (5/1038)

BACKGROUND: The efficacy of endoscopic biopsy surveillance of Barrett's oesophagus in reducing mortality from oesophageal cancer has not been confirmed. AIMS: To investigate the impact of endoscopic biopsy surveillance on pathological stage and clinical outcome of Barrett's carcinoma. METHODS: A clinicopathological comparison was made between patients who initially presented with oesophageal adenocarcinoma (n = 54), and those in whom the cancer had been detected during surveillance of Barrett's oesophagus (n = 16). RESULTS: The surveyed patients were known to have Barrett's oesophagus for a median period of 42 months (range 6-144 months). Prior to the detection of adenocarcinoma or high grade dysplasia, 13 to 16 patients (81%) were previously found to have low grade dysplasia. Surgical pathology showed that surveyed patients had significantly earlier stages than non-surveyed patients (p = 0.0001). Only one surveyed patient (6%) versus 34 non-surveyed patients (63%) had nodal involvement (p = 0.0001). Two year survival was 85.9% for surveyed patients and 43.3% for non-surveyed patients (p = 0.0029). CONCLUSIONS: The temporal course of histological progression in our surveyed patients supports the theory that adenocarcinoma in Barrett's oesophagus develops through stages of increasing severity of dysplasia. Endoscopic biopsy surveillance of Barrett's oesophagus permits detection of malignancy at an early and curable stage, thereby potentially reducing mortality from oesophageal adenocarcinoma.  (+info)

Barrett's oesophagus. (6/1038)

Barrett's oesophagus represents the replacement of stratified squamous epithelium by metaplastic columnar epithelium for 3 cm of the distal oesophagus. Gastro-oesophageal reflux, which affects 40% of the adult population, is the principal aetiological factor. This results in predominantly acid but also bile reflux (due to duodenogastrooesophageal reflux) through the lower oesophageal sphincter, transient relaxation of which accounts for the main mechanism of reflux. Conventional Barrett's oesophagus is reported in 11-13% of patients with symptomatic reflux and short segment Barrett's oesophagus (< 3.0 cm) in 18%. Approximately 50% of these patients have recognised complications on presentation, eg, carcinoma (15%). The disparity between clinical symptoms and endoscopic severity is due to reduced oesophageal mucosal sensitivity as a consequence of prolonged mucosal acid exposure. These rather alarming figures combined with the knowledge that Barrett's oesophagus is a pre-malignant condition (the diagnosis is associated with a 25-130-fold increase of malignancy) may account for the substantial increase in junctional gastrooesophageal malignancies. Symptomatic Barrett's oesophagus should be managed with full-dose proton pump inhibitors, eg, lansoprazole. Anti-reflux surgery should be reserved for the medically fit patient with recurrent symptomatic relapse in the histological absence of premalignant change. There is no evidence suggesting that surgery can be used as a prophylactic measure against malignancy. Encouraging short-term results have been obtained with photodynamic therapy in the management of high-grade dysplasia. However, columnar epithelium has been found underlying the regenerated squamous epithelium, suggesting that life-long surveillance is warranted.  (+info)

Toxic bile acids in gastro-oesophageal reflux disease: influence of gastric acidity. (7/1038)

BACKGROUND: Bile acid toxicity has been shown in the gastric, colonic, and hepatic tissues; the effect on oesophageal mucosa is less well known. AIMS: To determine the spectrum of bile acids refluxing in patients with gastro-oesophageal reflux disease and its relation to oesophageal pH using a new technique of combined oesophageal aspiration and pH monitoring. METHODS: Ten asymptomatic subjects and 30 patients with symptoms of gastro-oesophageal reflux disease (minimal mucosal injury, erosive oesophagitis (grade 2 or 3 Savary-Miller), Barrett's oesophagus/stricture; n=10 in each group) underwent 15 hour continuous oesophageal aspiration with simultaneous pH monitoring. Bile acid assay of the oesophageal samples was performed using modified high performance liquid chromatography. RESULTS: The peak bile acid concentration and DeMeester acid scores were significantly higher in the patients with oesophagitis (median bile acid concentration 124 micromol/l; acid score 20.2) and Barrett's oesophagus/stricture (181 micromol/l; 43. 3) than patients with minimal injury (14 micromol/l; 12.5) or controls (0 micromol/l; 11.1). The predominant bile acids detected were cholic, taurocholic, and glycocholic acids but there was a significantly greater proportion of secondary bile acids, deoxycholic and taurodeoxycholic acids, in patients with erosive oesophagitis and Barrett's oesophagus/stricture. Although bile acid reflux episodes occurred at variable pH, a temporal relation existed between reflux of taurine conjugates and oesophageal acid exposure (r=0.58, p=0.009). CONCLUSION: Toxic secondary bile acid fractions have been detected in patients with extensive mucosal damage. Mixed reflux is more harmful than acid reflux alone with possible toxic synergism existing between the taurine conjugates and acid.  (+info)

Hypothesis: the changing relationships of Helicobacter pylori and humans: implications for health and disease. (8/1038)

Helicobacter pylori has apparently colonized the human stomach since time immemorial and is superbly adapted for persistence. Several genotypes, including cag+, are associated with increased risk of gastric and duodenal diseases. With modern life, for probably the first time in human history, there are large numbers of noncolonized persons. Duodenal ulceration has been present essentially for only 200 years; that its incidence rose just as H. pylori was waning is best explained by changes in gastric microecology. As H. pylori is disappearing, duodenal ulceration and gastric cancer rates are falling. However, more proximal diseases, gastroesophageal reflux (GERD), Barrett's esophagus, and adenocarcinomas of the gastric cardia and lower esophagus, are increasing; colonization with cag+ H. pylori strains appears protective against these diseases. Thus, in the 21st century, the continuing decline in H. pylori may lead to the disappearance of duodenal ulcers and distal gastric cancers and toward a marked increase in GERD, Barrett's esophagus, and esophageal adenocarcinoma.  (+info)

There are many health risks associated with tobacco use, but for Barretts esophagus patients the risk of esophageal cancer from smoking may be even higher.
DOWNERS GROVE, Ill. - May 21, 2014 - According to a new systematic review article, radiofrequency ablation and complete endoscopic resection are equally effective in the short-term treatment of dysplastic Barretts esophagus, but adverse event rates are higher with complete endoscopic resection. The article comparing the two treatments appears in the May issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE). Barretts esophagus is a condition in which the lining of the esophagus changes and becomes more like the lining of the small intestine. It is believed that Barretts esophagus (BE) occurs because of chronic inflammation resulting from long-standing Gastroesophageal Reflux Disease (GERD). Barretts esophagus is more common in Caucasian males older than the age of 50 who have had GERD for greater than five years. Most patients with Barretts esophagus will not develop cancer. However, in some ...
Background: There is a need for improved tools to detect high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in patients with Barretts esophagus. In previous work, we demonstrated that a 3-tier classifier predicted risk of incident progression in Barretts esophagus. Our aim was to determine whether this risk classifier could detect a field effect in nondysplastic (ND), indefinite for dysplasia (IND), or low-grade dysplasia (LGD) biopsies from Barretts esophagus patients with prevalent HGD/EAC.. Methods: We performed a multi-institutional case-control study to evaluate a previously developed risk classifier that is based upon quantitative image features derived from 9 biomarkers and morphology, and predicts risk for HGD/EAC in Barretts esophagus patients. The risk classifier was evaluated in ND, IND, and LGD biopsies from Barretts esophagus patients diagnosed with HGD/EAC on repeat endoscopy (prevalent cases, n = 30, median time to HGD/EAC diagnosis 140.5 days) and nonprogressors ...
Patients with Barretts esophagus without abnormal cells: endoscopic eradication therapy is not recommended.. If eradication therapy is not indicated, is not available or is declined by a patient with Barretts esophagus, surveillance by endoscopy should be performed every three months in patients with high-grade dysplasia, every six to 12 months in patients with low-grade dysplasia, and every three to five years in patients with no dysplasia.. The recommendations in the medical position statement were made under the assumption that a patients diagnosis and the presence or absence of low and high grade dysplasia would be accurate to the highest degree possible using the best current standards of practice, according to Stuart J. Spechler, MD, AGAF, a member of the AGA Institute Medical Position Panel. High grade dysplasia is an abnormal growth that has a high risk for cancer development.. Most patients (70 to 80 percent) with high-grade dysplasia can be successfully treated with endoscopic ...

Esophageal adenocarcinoma (EAC) is an often deadly cancer with a rising incidence in Western countries. Chronic gastroesophageal reflux disease is associated with the metaplastic transformation of normal squamous epithelium to premalignant specialized intestinal metaplasia within the esophagus (Barretts esophagus). Barretts esophagus may progress to low-grade dysplasia (LGD), high-grade dysplasia (HGD), or even EAC. Although nondysplastic Barretts esophagus progresses to EAC at a rate of 0.5% per year, rates of progression for true LGD and HGD are significantly higher. Treatment is mandatory for HGD and may be appropriate in select patients with nondysplastic Barretts esophagus and many with LGD. Thus, accurate pathologic assessment is necessary before considering endoscopic therapy. Previously, only esophagectomy was offered to patients with HGD or EAC. However, esophagectomy has significant morbidity and mortality, and therefore endoscopic therapies have been advocated for early Barretts ...
A set of 19 micro-RNAs (miRNAs) is associated with the likelihood of progression of Barretts esophagus to esophageal dysplasia or adenocarcinoma within seven years. Because Barretts esophagus confers a 5-fold elevated risk for esophageal cancer, all patients diagnosed with Barretts esophagus are monitored yearly with invasive and costly procedures. However, only about 1% of Barretts esophagus patients progress to adenocarcinoma suggesting that a large number of patients are being monitored unnecessarily. The 19 miRNAs can help predict with over 95% accuracy which Barretts esophagus patients are unlikely to progress, avoiding the cost of unnecessary medical monitoring.. ...
Background: The risk of developing Barretts esophagus (BE) and/or esophageal adenocarcinoma (EAC) is associated with specific demographic and behavioral factors, including gender, obesity/elevated body-mass index (BMI), and tobacco use. Alterations in DNA methylation, an epigenetic modification that can affect gene expression and that can be influenced by environmental factors, is frequently present in both BE and EAC and is believed to play a role in the formation of BE and its progression to EAC. It is currently unknown whether obesity or tobacco smoking influence the risk of developing BE/EAC via the induction of alterations in DNA methylation. To investigate this possibility, we assessed the genome-wide methylation status of 81 esophageal tissues, including BE, dysplastic BE, and EAC epithelia using HumanMethylation450 BeadChips (Illumina). Results: We found numerous differentially methylated loci in the esophagus tissues when comparing males to females, obese to lean individuals, and smokers to
According to the Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), Barretts Esophagus is a condition marked by intestinal metaplasia. This means the tissue lining the esophagus (the muscular tube that runs from the mouth to the stomach) is replaced by tissue of the type that normally lines the intestines. The problem with having Barretts Esophagus is that it can be a precursor to an often deadly malignancy -- cancer of the esophagus. In fact, the Mayo Clinic web site notes that people with Barretts Esophagus have a 30 to 40 times elevated risk of developing esophageal adenocarcinoma (a type of esophageal cancer). And, unfortunately, theres no treatment for Barretts Esophagus; it can only be monitored. But new research just published in the March issue of the journal Gastroenterology concludes theres a non-drug way to slash the risk of developing Barretts Esophagus. Scientists at the Kaiser Permanente Division of Research have found that drinking one glass of wine a day ...

The cells lining the esophagus differ from those lining the stomach or intestines, mainly because they have different functions. They also have a distinctly different appearance, so it is usually easy for a physician to tell them apart when examining the esophagus and stomach. Normally, there is an area at the end of the esophagus that marks the border between the cells of the esophagus and those of the stomach. Barretts esophagus is the abnormal growth of intestinal-type cells above this border, into the esophagus.. The Barretts cells may help protect the esophagus from acid exposure. It may protect the normal tissue in the esophagus against further damage by GERD. This may explain why the symptoms of GERD seem to lessen in some patients with Barretts esophagus. Unfortunately, these tissue changes may be a forerunner of cancer of the lower esophagus, known as adenocarcinoma. Another type of cancer of the esophagus is squamous cell cancer. It is more often formed in the upper esophagus and is ...

As the incidence and mortality of esophageal adenocarcinoma continue to increase, strategies to counter this need to be explored. Screening for Barretts esophagus, which is the known precursor of a large majority of adenocarcinomas, has been debated without a firm consensus. Given evidence for and against perceived benefits of screening, the multitude of challenges in the implementation of such a strategy and in the downstream management of subjects with Barretts esophagus who could be diagnosed by screening, support for screening has been modest. Recent advances in the form of development and initial accuracy of noninvasive tools for screening, risk assessment tools, and biomarker panels to risk stratify subjects with BE, have spurred renewed interest in the early detection of Barretts esophagus and related neoplasia, particularly with the advent of effective endoscopic therapy. In this review, we explore in depth the potential rationale for screening for Barretts esophagus, recent advances that

Much has been written about Barretts esophagus and the resultant dysplastic changes that may degenerate into adenocarcinoma of the esophagus. Until now there has been little to offer patients suffering from this premalignant lesion of the esophagus besides a devastatingly difficult esophagectomy. Now, a revolutionary approach promises to shed light on this usually asymptomatic condition.. But first, lets review Barretts. Barretts esophagus derives its name from the British surgeon Norman Barrett. Barrett first described this condition as a congenitally short esophagus that tethered the stomach into the mediastinum resulting in esophageal ulcers.. Later, in 1953, the presence of reflux esophagitis and its associated columnar mucosa was described. Over the next several decades the definition of Barretts esophagus has evolved into the finding of columnar-appearing mucosa in the distal esophagus or intestinal metaplasia on biopsy through upper gastrointestinal endoscopy.. Intestinal ...
The role of environmental factors is evident from the short time period over which the incidence of Barretts oesophagus6 and oesophageal adenocarcinoma7 has increased. Furthermore, the demonstration of a birth cohort effect, with higher incidence rates in younger cohorts,8 would support the idea that exposure to environmental factors in early life is an important determinant of risk. Identification of specific environmental exposures is difficult, but factors that increase gastro-oesophageal reflux, such as dietary components, increasing body mass index and eradication of Helicobacterpylori, may be relevant.9 Whether or not smoking and alcohol consumption are risk factors for Barretts oesophagus is controversial; however, an association was found in a recent population study.10 In order for an individual to develop Barretts oesophagus, and in some cases oesophageal adenocarcinoma, these environmental exposures probably need to interact with genetically determined characteristics that define ...
TY - JOUR. T1 - Acidic Bile Salts Induce Epithelial to Mesenchymal Transition via VEGF Signaling in Non-Neoplastic Barretts Cells. AU - Zhang, Qiuyang. AU - Agoston, Agoston T.. AU - Pham, Thai H..

Y1 - 2019/1/1. N2 - Background & Aims: Metaplastic glands buried under squamous epithelium are frequently detected in patients with Barrett esophagus (BE). This subsquamous intestinal metaplasia might be responsible for cancers that develop despite endoscopic surveillance and for metaplasia recurrences after endoscopic ablation. To determine whether reflux induces BE cells to undergo an epithelial-to-mesenchymal transition (EMT) that produces subsquamous intestinal metaplasia, we assessed EMT in BE cells exposed to acidic bile salts and in rat and human esophageal tissues. Methods: We compared markers of EMT ...
Results The sample was mainly male (75%, n = 6,327) with median age of 64 years (range 18-92 years, n = 6,327). Median Barretts length was 4 cm (range 1-24 cm, n = 6,029) and median time since diagnosis of Barretts was 2 years (range 0-41 years, n = 5,805). At least one symptom of reflux was experienced by 60% of patients and 46% of patients experienced at least one symptom at least once per week (n = 1,072). Length of Barretts was associated with age (n = 6,029), gender (n = 6,029), presence of low grade dysplasia (n = 5,955), presence of intestinal metaplasia (n = 6,026) and time since diagnosis (n = 5,913). ...

To determine whether or not flow-cytometric evidence of aneuploidy and increased G2/tetraploid fractions predispose to neoplastic progression in Barretts esophagus, 62 patients with Barretts esophagus were evaluated prospectively for a mean interval of 34 months. Nine of 13 patients who showed aneuploid or increased G2/tetraploid populations in their initial flow-cytometric analysis developed high-grade dysplasia or adenocarcinoma during follow-up; none of the 49 patients without these abnormalities progressed to high-grade dysplasia or cancer (P less than 0.0001). Neoplastic progression was characterized by progressive flow-cytometric and histological abnormalities. Patients who progressed to high-grade dysplasia and carcinoma frequently developed multiple aneuploid populations of cells that were detectable flow-cytometrically. Similarly, patients appeared to progress through a phenotypic sequence that could be recognized histologically by the successive appearance of Barretts metaplasia ...
P53_HUMAN] Note=TP53 is found in increased amounts in a wide variety of transformed cells. TP53 is frequently mutated or inactivated in about 60% of cancers. TP53 defects are found in Barrett metaplasia a condition in which the normally stratified squamous epithelium of the lower esophagus is replaced by a metaplastic columnar epithelium. The condition develops as a complication in approximately 10% of patients with chronic gastroesophageal reflux disease and predisposes to the development of esophageal adenocarcinoma. Defects in TP53 are a cause of esophageal cancer (ESCR) [MIM:133239]. Defects in TP53 are a cause of Li-Fraumeni syndrome (LFS) [MIM:151623]. LFS is an autosomal dominant familial cancer syndrome that in its classic form is defined by the existence of a proband affected by a sarcoma before 45 years with a first degree relative affected by any tumor before 45 years and another first degree relative with any tumor before 45 years or a sarcoma at any age.

Chicago - New guidelines issued by the American Gastroenterological Association (AGA) support the use of radiofrequency ablation (RFA) to remove precancerous cells in patients with Barretts esophagus, a condition most commonly caused by chronic acid reflux, or GERD. Barretts esophagus is the leading cause of esophageal cancer and affects an estimated two million Americans. While traditionally managed through watchful waiting, experts at Northwestern Medicines Center for Esophageal Disease have been among the pioneers of ablation treatment and have long seen the benefits of early treatment.. Frequent heartburn, regurgitation, and trouble swallowing are common symptoms of GERD (gastroesophageal reflux disease), which experts believe is the result of stomach contents washing back into the esophagus leading to the development of Barretts Esophagus. Repeat exposure to stomach acids can result in damage to the esophagus and cause healthy cells to transform into these precancerous cells. ...
Barretts esophagus is a premalignant condition of the distal esophagus that increases the risk of esophageal cancer. Unfortunately, screening for Barretts esophagus currently requires endoscopy, an invasive and expensive procedure, and thus, it is not routinely performed. Moinova et al. have now demonstrated a simplified approach to screening by identifying a pair of DNA methylation markers that correlate with the presence of Barretts esophagus. The authors also invented a swallowable balloon-based device that can capture DNA samples for methylation analysis and found that it is well tolerated in patients and provides ,90% sensitivity and specificity compared to endoscopy, suggesting its potential as a screening method. ...
A subepitheal myofibroblastic (SMF) cell layer has been described in the colon, and referred to as pericryptal myofibroblastic cell layer. SMF cells have been shown to produce basement membrane proteins, including type IV collagen and laminin. The aim of this work was to determine the status of the SMF cell layer in Barretts metaplasia (BM), with and without dysplasia, and compare that to the previously reported distribution of SMF in normal colon and colonic adenomas and carcinoma. Sections of formalin-fixed, paraffin-embedded biopsies from 6 colonic adenomas and 5 colonic adenocarcinomas, as well as 4 cases of BM without dysplasia, 4 with low grade dysplasia, 4 high grade dysplasia and 4 with invasive adenocarcinoma were immunohistochemically stained for alpha smooth muscle actin using the immunoperoxidase method. A continuous layer of SMF cells was present in all normal colonic tissue and adenomas but was absent in all colorectal adenocarcinomas. Surprisingly, none of the cases of BM with or without
A diagnosis of negative for dysplasia is applied to cases that show metaplastic columnar epithelium with regenerative changes. Unfortunately, on occasion, epithelial regenerative changes may be extreme, particularly in mucosa adjacent to the neo-squamocolumnar junction or in which active inflammation or ulceration is present. In my experience, the tendency among surgical pathologists to overinterpret regenerative changes as indicative of dysplasia is often due to a lack of awareness of the wide spectrum of atypia that may occur in patients with Barretts oesophagus, particularly those with persistent reflux. From a biological perspective, the progression of Barretts oesophagus to adenocarcinoma is driven by the evolution and proliferation of clones of cells with accumulated genetic errors, a process referred to as genomic instability.13,14 In fact, the process of clonal evolution begins early in Barretts oesophagus, before the phenotypic expression of dysplasia, when metaplastic epithelial ...
Barretts esophagus is a disorder in which the lining of the esophagus is damaged by stomach acid. People suffering from this disorder are at an increased risk for esophageal cancer.

Cell lines and culture conditions. Barretts esophageal adenocarcinoma cell lines (SEG-1, FLO-1, and BIC-1) were used in this study. These cell lines were derived from surgically resected tissues of human Barretts esophageal adenocarcinoma (generously provided by Dr. David G. Beer, University of Michigan, Ann Arbor, MI). SEG-1 cells were cultured in DMEM, and FLO-1 and BIG-1 cells were cultured in high-glucose DMEM, with l-glutamine (Life Technologies, Inc.) supplemented with 10% fetal bovine serum (Gemini Biologicals), 100 units/mL penicillin G sodium, 100 μg/mL streptomycin, and 0.25 μg/mL amphotericin B (Life Technologies), and maintained in a monolayer culture at 37°C in humidified air with 5% CO2. Cellular morphology was observed through a phase-contrast microscope during culture and experiments.. Reagents.

Radiofrequency Ablation for Barretts Esophagus is a procedure that can minimize or prevent abnormal cells from becoming esophageal cancer.. The physicians at Atlantic Digestive Specialists use BARRX, a new option to treat Barretts Esophagus, a condition in which abnormal tissue forms in the lining of the esophagus often as a result of Gastroesophageal Reflux Disease (GERD). These cells can become cancerous. By ablating, or removing, these cells our physicians can aid in preventing the tissue from developing into cancer. The abnormal cells are destroyed using the radiofrequency BARRX system and new, healthy cells replace them.. Our physicians perform this procedure in conjunction with an upper endoscopy. No incisions or surgery is needed. An upper endoscope is gently inserted through the nose and moved around the bends of the esophagus and stomach. The endoscope has a light and camera at the tip to allow our physicians to view the lining of the esophagus. A sizing balloon measures the esophagus ...
Acid and bile coming from the stomach into the oesophagus may cause heartburn.. The normal oesophagus (gullet or food pipe) is lined with a pinkish-white tissue called squamous epithelium (left image).. Barretts Oesophagus is a clear precursor of oesophageal adenocarcinoma (AC) but because it is so under-diagnosed, patients with AC have not been aware of it.. Barretts oesophagus is a condition in which the normal squamous epithelium of the oesophagus has been replaced by an abnormal red columnar epithelium (right image).. In the US it is referred to as esophageal cancer / cancer of the esophagus.. Diagnosis , Treatments , Complications , Donate ...
Our goal was to determine whether acid or bile salt exposure results in gene expression patterns that reflect changes in biological processes within the cell. Previous work in cell lines demonstrated that short exposure to acid results in activation of mitogen-activated protein kinase pathways that contribute to cell proliferation[5]. Work performed in primary Barretts tissues also showed that only short and not continuous exposure to acid results in increased PCNA expression, a marker of DNA replication, as determined by the number of positive staining cells using immunohistochemistry[8]. Despite using different periods of acid exposure, increased cell proliferation in esophageal adenocarcinoma cell lines was not detected using direct cell counting, colorimetric MTT assays, or [3H]thymidine uptake. Changes in PCNA levels as determined by protein immunoblotting also was not detected (data not shown). Changes in PCNA expression, however, may be difficult to detect in cancer cell lines like SEG-1 ...
A total of 148 procedures were performed in 38 included patients in the study between January 2010 and May 2012.. Mean age was 66 (±12) years, 34 were men. Of these, 23 had high grade dysplasia (HGD), 14 had low grade dysplasia (LGD), 1 had intramucosal carcinoma (IMC). Six patients required EMR prior to RFA. At median follow-up of 18 months, 100% have complete remission of dysplasia (CR-D) and 73% have complete remission of metaplasia and dysplasia (CR-IM, CR-D) with 2± 0.63 RFAs and 0.36±0.92 EMRs.. Three patients were found to have early cancer whilst progressing through the protocol. Two of these developed a nodule after undergoing four radiofrequency ablations and the third patient developed a nodule after 1 RFA.. For 772 patient-years of follow-up, there were 4 adverse events: 1 patient had post procedure chest pain, 1 patient had a minor post EMR bleed, 1 patient had minor bleeding post RFA and 1 had a mucosal tear post RFA.. Therefore, the complication rate was 2.70% (95%CI ...
With the change in season we have the opportunity to reevaluate our patients as they seek flu shots and treatment for seasonal allergies. We now offer esophageal ablation for select patients with gastroesophageal reflux disease disease and Barretts esophagus. The Barrx system allows for cauterization of Barretts or columnar epithelium and then reepithelialization of normal squamous mucousa.. As you know, 20% of people complain of reflux at least once a week. The American College of Physician guidelines recommends endoscopy in patients with new onset dyspepsia or reflux after the age of 50. Endoscopy should be considered in Caucasian males over the age of 40 who have had reflux symptoms for over 10 years. About 10% of patients with reflux develop Barretts esophagus. They have a 30-40 fold risk of developing adenocarcinoma. Because of this risk endoscopic surveillance is performed every 3 years unless dysplasia is found. Twenty five to forty percent of patients with untreated high grade ...
Patients with Barretts Esophagus are known to have excessive distal esophageal acid exposure comparable to patients with erosive esophagitis. A significant proportion of patients with BE who are not symptomatic on treatment continue to have persistent acid reflux. High dose esomeprazole is able to control acid reflux in patients with BE. The effect of acid reflux on Barretts esophagus stroma is currently unknown.. It is our hypothesis that stromal fibroblast activation in Barretts esophagus is influenced by acid reflux. The specific aim of this proposal will be: To assess the association between acid reflux and subepithelial fibroblasts in Barretts esophagus. ...

A new study reports that multipolar electrocoagulation in combination with acid suppression is a safe and effective method to ablate nondysplastic Barretts esophagus over the long term. No adenocarcinoma (cancer) or high-grade dysplasia of the esophagus developed in any of the study patients. This is the largest published series and longest follow-up of patients with nondysplastic Barretts esophagus who underwent ablation therapy with multipolar electrocoagulation. The study appears in the April issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).. Barretts esophagus is a condition where the lining of the esophagus changes because of chronic inflammation, generally due to gastroesophageal reflux disease (GERD). In the setting of chronic acid exposure, the cellular structure of the lower esophageal lining changes to look more like the cells lining the intestine. Barretts esophagus itself has no ...

Flavonoids, polyphenolic compounds concentrated in fruits and vegetables, have experimentally demonstrated chemopreventive effects against esophageal and gastric cancer and Barretts esophagus, a precursor lesion for esophageal adenocarcinoma. Few epidemiologic studies have examined flavonoids and incidence of esophageal and gastric cancers, and none have considered flavonoids with survival. Additionally, only one epidemiologic investigation has reported an inverse association between isoflavone intake and Barretts esophagus risk, yet no study has considered other flavonoid classes, which are more commonly consumed in the U.S. This ancillary study built upon the U.S. Multi-Center Study (esophageal adenocarcinoma cases n=274, gastric cardia adenocarcinoma cases n=248, esophageal squamous cell carcinoma cases n=191, other gastric adenocarcinoma cases n=341, and frequency-matched controls n=662) and the Study of Reflux Disease (Barretts esophagus cases n=170 and matched controls n=183). ...
There are several studies in the literature on CK expression in Barretts epithelium and the gastric cardia. Intestinal metaplasia in Barretts oesophagus and intestinal metaplasia of the gastric cardia can be distinguished on the basis of CK7 and CK20 expression.6-8 The largest study7 showed that a CK7+/CK20− phenotype had a positive predictive value of 87% for the diagnosis of adenocarcinoma of the distal oesophagus. About 90% of Barretts cancers were positive for CK7 but less than 18% expressed CK20.7 The same phenotype was found in only 24% of cancers located in the proximal stomach. Others confirmed these results.9-11 However, other studies have produced contradictory results, and have shown that CK7 but and CK20 immunoreactivity did not differentiate between Barretts adenocarcinoma and gastric cancer located at the cardia.12-15 Our present study is in line with these results. In one study, the CK phenotype was used to try to differentiate short segment Barretts intestinal metaplasia ...

Previous studies of hypermethylation in Barretts esophagus and EAC have been limited to the CDKN2A gene and have focused on the analysis of a very small number of samples from each patient with Barretts esophagus and/or esophageal adenocarcinoma. In this study, we have used an alternative approach that not only documents the occurrence of hypermethylation of four CpG islands (APC, CDH1, CDKN2A, and ESR1) but also provides the topological context in which this hypermethylation occurs in histologically defined areas of Barretts-associated EAC. Because this experimental approach by necessity involves the analysis of a large number of samples per patient, we have restricted the number of cases to six. Although the limited number of patients does not allow us to extrapolate on the general occurrence of hypermethylation of these four genes in Barretts-associated EAC, this alternative strategy revealed interesting trends.. Our results demonstrate two important points:. (a) Abnormal methylation ...

Barretts esophagus is a complication of chronic acid reflux, also known as gastroesophageal reflux disease (GERD). Acid reflux occurs when stomach acid backs up into your esophagus. This frequently results in heartburn and can occasionally cause damage to the lining of the esophagus. Stomach acid can cause damage to your esophagus because the lining in your esophagus is not equipped to protect itself against gastric acid. As the esophagus tries to heal, your cells may change in order to adapt and protect the esophagus. These changes can increase your risk of developing esophageal cancer. One change that can occur is called metaplasia: the process of the reversible substitution of a distinct kind of cell with another mature cell of another differentiated kind. This occurs when the body starts growing intestinal cells, rather than esophageal cells, in the esophagus because of the acid influx. If the stimulus that caused the metaplasia is removed, tissues can return to their normal pattern of ...

One change that can occur is called metaplasia: the process of the reversible substitution of a distinct kind of cell with another mature cell of another differentiated kind. This occurs when the body starts growing intestinal cells, rather than esophageal cells, in the esophagus because of the acid influx. If the stimulus that caused the metaplasia is removed, tissues can return to their normal pattern of ...
Barretts esophagus is a complication of chronic acid reflux, also known as gastroesophageal reflux disease (GERD). Acid reflux occurs when stomach acid backs up into your esophagus. This frequently results in heartburn and can occasionally cause damage to the lining of the esophagus.

N2 - Radiofrequency ablation (RFA) with HALO system has been developed as a new treatment option for Barretts esophagus (BE). It had been observed that some patients had esophageal eosinophilia (EE) infiltration after RFA. The incidence and features of EE after RFA were systematically determined. From a prospectively compiled database, data on 148 patients who underwent RFA for BE were analyzed. Biopsies were taken pre- and post-RFA from the BE segment, and histological sections of the biopsy specimens were stained with hematoxylin and eosin, and examined by a gastrointestinal pathologist. The incidence of EE post-RFA was then determined. Of the 148 patients, 120 (81%) were men, 137 (92%) were white, 64 (43%) were overweight and 49 (33%) obese, and 128 (86%) were over 50 years of age or more. Four (2.7%) ...
June 16, 2011 /Press Release/ -- The risk of cancer associated with the condition known as Barretts esophagus may be lower than previously thought, according to a new long-term study. The findings suggest the recommended routine cancer screenings among Barretts esophagus patients are based on inflated estimates of cancer risk and may not be necessary. It emphasizes the need to not only identify those with who have Barretts esophagus but also to then identify those who will go on to possibly develop cancer, since most will not. We can then create a more selective approach to the one to two percent of Americans who have Barretts, said Dr. Sharmila Anandasabapathy, an associate professor of medicine and gastroenterology, and medical director of endoscopy at The Mount Sinai Medical Center in New York City.

INTRODUCTION: Endoscopic evaluation with high-definition white light endoscopy and random 4-quadrant biopsy (Seattle Protocol) is the current standard of care for the detection of Barretts esophagus (BE). Recently, enhanced imaging technologies have become available to provide real-time diagnosis of intestinal metaplasia (IM) and dysplasia, reducing the need for tissue biopsy. Probe-based confocal laser endomicroscopy (pCLE) provides dynamic microscopic mucosal views, rapidly capturing digital images that become optical biopsies. This study examined the role of pCLE in BE screening and surveillance as compared to the Seattle Protocol.. METHODS: Patients undergoing BE screening or surveillance endoscopy were enrolled at eight US centers. Optical biopsy using pCLE was interpreted in real time. Endoscopists performing pCLE were new users with a median experience of 8.5 months and no formal training in surgical pathology. Seattle Protocol biopsies were then taken. Recorded pCLE images were reviewed ...

BM may present as a cellular mosaic with irregular tongues of intestinal epithelia, varying areas of dysplasia and other intermediate markers for cancer risk. These areas may be missed on routine biopsy. If such areas cannot be readily relocated, chemopreventive studies will remain unfeasible. Methods: Utilizing a specially adapted upper gastroscope (Pentax Precision Instruments) that is able to accurately evaluate distance from incisors and endoscopic rotation, chromoendoscopy with toluidine blue and systematic mapping (4 quadrant jumbo biopsies at 1 cm intervals) was ...
Barretts esophagus (BE) is an intestinal metaplasia that occurs in the setting of chronic acid and bile reflux and is associated with a risk for adenocarcinoma. Expression of intestine-specific transcription factors in the esophagus likely contributes to metaplasia development. Our objective was to explore the effects of an intestine-specific transcription factor when expressed in the mouse esophageal epithelium. Transgenic mice were derived in which the transcription factor Cdx2 is expressed in squamous epithelium using the murine Keratin-14 gene promoter. Effects of the transgene upon cell proliferation and differentiation, gene expression, and barrier integrity were explored. K14-Cdx2 mice express the Cdx2 transgene in esophageal squamous tissues. Cdx2 expression was associated with reduced basal epithelial cell proliferation and altered cell morphology. Ultrastructurally two changes were noted. Cdx2 expression was associated with dilated space between the basal cells and diminished ...

Activation of hedgehog (Hh) signaling contributes to the progression of Barretts esophagus (BE), which increases the risk of esophageal adenocarcinoma. Recent clinical studies revealed that proton-pump inhibitors (PPIs) but not H2 receptor antagonists (H2RAs) were associated with a decreased risk of esophageal adenocarcinoma. We would like to know whether PPIs interfere with BE progression during BE treatment. Here, we explored the role of omeprazole on Hh signaling and expression of two crucial biomarkers of BE, SOX9 and CDX2. We demonstrated that bile acids elevated expression of Hh pathway target genes, such as GLI1 and PTCH1, and induced SOX9 and CDX2 up-regulation in both CP-A and CP-B cells. Omeprazole, but not famotidine, down-regulated these genes induced by bile acids. In addition, omeprazole-induced down-regulation of SOX9 and CDX2 was mediated by Hh signaling. To explore the mechanisms by which omeprazole inhibits Hh signaling, we performed luciferase assay but did not find any ...

Barretts oesophagus, pill camera view. This is a condition in which the epithelial cells at the lower part of the oesophagus (gullet) change, a process called metaplasia. It is caused by chronic acid reflux, where stomach acids escape from the stomach into the oesophagus. This causes heartburn. Over time, the normal squamous cells found in the oesophagus are replaced by columnar cells, similar to those that line the stomach or colon. The condition is considered a precursor of oesophageal cancer. Treatment is with drugs to reduce stomach acid production, although advanced cases may require surgery or cancer treatments. A pill camera is a pill-sized camera swallowed to visualise the digestive tract. - Stock Image M120/0166

In tetrapods, the pharynx is much shorter, and the esophagus correspondingly longer, than in fish. In the majority of vertebrates, the esophagus is simply a connecting tube, but in some birds, which regurgitate components to feed their young, it is extended towards the lower end to form a crop for storing food before it enters the true stomach.[36][37] In ruminants, animals with four stomachs, a groove called the sulcus reticuli is often found in the esophagus, allowing milk to drain directly into the hind stomach, the abomasum.[38] In the horse the esophagus is about 1.2 to 1.5 m (4 to 5 ft) in length, and carries food to the stomach. A muscular ring, called the cardiac sphincter, connects the stomach to the esophagus. This sphincter is very well developed in horses. This and the oblique angle at which the esophagus connects to the stomach explains why horses cannot vomit.[39] The esophagus is also the area of the digestive tract where horses may suffer from choke. The esophagus of snakes is ...
Endoscopic mucosal resection of the esophagus was found to be safe and easy to perform. Efforts must be made to detect early m1 to m2 cancers, which are indicated for EEMR. It is necessary to perform periodic endoscopic examination. During endoscopic examination, it is important to wash the inside of the esophagus with water and perform careful observation. Also, in high-risk patients and patients with abnormalities, such as erythema, turbidity, or hypervascularity, iodine staining should be performed frequently. Patients at high risk for esophageal cancer include (1) men more than 55 years old who are heavy smokers and drinkers; (2) patients with cancer of the head and neck region; and (3) individuals with a family history of cancer and those with achalasia, corrosive esophagitis, or Barretts esophagus.

lymphoma (lymphocytes cancer), and cancer that has metastasized (spread from elsewhere in the body).. Cancer can happen anywhere in the persons esophagus. It can appear as a lump, plaque (abnormal flat part), or narrowing of the Esophagus. Esophageal cancer is most likely to occur in individuals with narrowed Esophagus, because they use to swallow a strong alkali in past, such as lye used for cleaning. Cancer of esophagus is also likely to occur in people with achalasia (when a esophageal sphincter fails to open properly), neck and head cancer, and esophageal blockage includes the esophageal web. Alcohol and smoking abuse also increase the risk of cancer of esophagus; and they are the major risk factors for squamous cell carcinomas..
