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.
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 ...

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 ...

Esophageal cancer is the ...
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
Prospective pilot study to be performed in 14 Barretts Esophagus patients with low grade and high grade dysplasia, referred for standard of care treatment. Patients will receive treatments with carbon dioxide Polar Wand cryotherapy at 0, 2 and 4 months, followed by surveillance endoscopy with four quadrant biopsies throughout the entire Barretts esophagus (BE)segment at 6 months, followed by endoscopy with additional treatments (if needed) at 8 and 10 months, followed by a final surveillance endoscopy at 12 months, with four quadrant biopsies throughout the entire initial BE segment length ...
The programs surgeons have a proven record of accomplishment in performing successful primary laparoscopic fundoplication procedures that give most patients the relief they seek. They are also skilled in managing patients who have had previous unsuccessful antireflux surgeries.. Endoscopic mucosal resection (EMR) may be the treatment of choice for patients who have nodular Barretts esophagus or suspicious tissue that may be malignant.. Targeting Barretts Esophagus. It is important to evaluate patients with GERD for Barretts esophagus and determine the presence and/or level of dysplasia. Treatment strategies vary for each patient depending on the extent of the patients disease, age, and overall health. Surveillance is appropriate for some patients with mild disease or who are an advanced age.. The treatment model for Barretts esophagus with high-grade dysplasia or early esophageal cancers has shifted radically over the past five years. Esophagectomies or surgical removal of the esophagus is ...
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 ...

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 ...

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. ...
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.

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. ...

DUBLIN, March 26, 2019 /PRNewswire/ -- The "Barretts Esophagus Ablation Devices Market Report - United States - 2019-2025" report has been added to ResearchAndMarkets.coms offering.. Unit sales growth will be driven by an expansion in installed base and replacement sales of devices that have reached the end of their lifespan. Based on available purchase order data, prices varied significantly between manufacturers in 2018. Medtronics Barrx system was priced between $120,000 and $140,000 and CSA Medicals truFreeze was priced between $70,000 and $80,000. These prices do not reflect the true pricing, as is evident in the ASP reported between $31,000 and $32,000. Medtronic and CSA Medical tend to incorporate bundling deals with their disposable products, which explains the discrepancy between the purchase order data and reported ASP.

This thesis examines the role of multi modal imaging in Barretts oesophagus with a focus on detecting dysplasia and early cancer (EC). Firstly, the role of high definition (HD) imaging in routine clinical setting was studied using data from patients who have undergone Barretts· surveillance. The yield of dysplasia by HD endoscopy was compared to standard definition (SD) endoscopy in this study. The role of narrow band imaging (NBI) with magnification in characterising abnormal lesions detected during BO surveillance was evaluated by performing a meta- analysis of clinical studies. The role of autofluorescence imaging (AFI) in Barretts oesophagus was examined in detail with a view to understand the biological basis of autofluorescence and to improve the specificity of this technique as it is associated with significant false positive results in clinical studies. A meta-analysis was performed to identify whether AFI has a clinical advantage over white light endoscopy in detecting Barretts ...
The investigators primary outcome analysis was the histological proof of Barretts epithelium.. The team also assessed the correlation between the presence of Barretts epithelium and the needed number of biopsies to confirm Barretts epithelium for the 2 different procedures.. Magnifying endoscopy enabled the prediction of Barretts epithelium with a sensitivity of 100% and a specificity of 66%, respectively.. The investigators found that acetic acid-guided biopsies obtained 78% of tissues containing Barretts epithelium compared to 57% with random biopsies.. Dr Hoffmans team concludes, Magnifying endoscopy with acetic acid-guided biopsies is superior to standard video endoscopy with random biopsies. The number of biopsies needed to confirm Barretts epithelium is half as much when compared to random biopsies. ...

What is Barretts Esophagus? Barretts esophagus develops when the lining of the esophagus changes to resemble the lining of the intestine.
The outcome of patients with localized carcinoma of the esophagus remains dismal despite some advances in chemotherapy agents, an improved understanding of chemoradiobiology, and improvement in multidisciplinary care. The pathCR rates are approximately 27%.14 The therapeutic approach has been empiric for decades. Any substantial gains may not be anticipated by continued empiric approaches. Therefore, more attention to clinical biology may be needed and, more important, molecular biology and patient genetics. Deriving therapy based on the molecular biology of the tumor and patient genetics is a major challenge but a much-needed effort. However, at the current time, there is an opportunity to study the clinical biology of esophageal cancer.. ACA and SCC appear to have a distinct clinical profile. ACA occurs predominantly in white men and is often associated with increased body mass index and chronic gastroesophageal reflux disease, whereas SCC, although more common in men, is predominantly a ...
The screening of at-risk patients for Barretts esophagus, a precursor to esophageal cancer, has long been a goal for health systems. Currently, most patients with the condition remain undiagnosed, and more than 90% of individuals are identified after it has progressed into esophageal cancer via endoscopy, according to a 2018 paper in Digestive Diseases and Sciences. This late diagnosis translates into a five-year survival rate of less than 15%, while those cases caught during the Barretts esophagus stage and treated with endoscopic resection and/or ablation . . .

NEW ORLEANS -- Proton pump inhibitors (PPIs) are just as effective as laparoscopic surgery for patients with chronic gastroesophageal reflux disease, results of a multicenter clinical trial suggest.
OBJECTIVE: Oesophageal adenocarcinoma (OA) incidence has risen sharply in Western countries over recent decades. Local and systemic inflammation is considered an important contributor to OA pathogenesis. Established risk factors for OA and its precursor, Barretts oesophagus (BE), include symptomatic reflux, obesity and smoking. The role of inherited genetic susceptibility remains an area of active investigation. Here, we explore whether germline variation related to inflammatory processes influences susceptibility to BE/OA. DESIGN: We used data from a genomewide association study of 2515 OA cases, 3295 BE cases and 3207 controls. Our analysis included 7863 single-nucleotide polymorphisms (SNPs) in 449 genes assigned to five pathways: cyclooxygenase (COX), cytokine signalling, oxidative stress, human leucocyte antigen and nuclear factor-κB. A principal components-based analytic framework was employed to evaluate pathway-level and gene-level associations with disease risk. RESULTS: We identified a
Biopsies taken at the time of endoscopy are sent for examination by a pathologist. The main thing we ask the pathologist to look for is "dysplasia." Dysplasia is a precancerous change (not cancer yet) which usually occurs before cancer ever develops. It can be thought of as an early warning signal and is often classified either as low grade or high grade dysplasia. Low grade dysplasia is seen most often and is less cause for concern. In this instance reflux must be controlled and surveillance needs to be more frequent. Endoscopic eradication therapy is a therapeutic option for the treatment of patients with confirmed low-grade dysplasia. Over time, dysplasia may progress from low grade to high grade, then sometimes to cancer. If high grade dysplasia is found, the risk of cancer is much greater. Patients with high grade dysplasia are candidates for eradication therapy such as radiofrequency ablation. If high grade dysplasia persists, there is a high risk of progression to cancer. In this ...
Esophageal adenocarcinoma typically arises in Barretts esophagus, following replacement of the normal stratified epithelium by specialized intestinal epithelium, and progressive transformation from metaplasia to low-grade dysplasia, high-grade dysplasia, and finally adenocarcinoma (reviewed in ref. 47). To determine the timing of EGFR mutations within this malignant transformation, we analyzed 5 cases of high-grade dysplasia as well as 21 cases of Barretts esophagus. In 8 of 21 cases, paired specimens of Barretts esophagus and adenocarcinoma were available for analysis. Three of 21 cases (14%) of Barretts esophagus had an EGFR mutation (Table 1): two had the delE746-A750 sensitizing EGFR mutation, whereas the third had the T790M drug-resistance mutation. This mutation is of particular interest because it was first identified as a secondary EGFR mutation associated with acquired resistance to gefitinib by reducing drug binding within the ATP pocket (28-31). However, we have recently reported ...
Barretts esophagus (BE) increases the risk of esophageal adenocarcinoma (EAC). We found the risk to be BE has been associated with single nucleotide polymorphisms (SNPs) on chromosome 6p21 (within the HLA region) and on 16q23, where the closest protein-coding gene is FOXF1. Subsequently, the Barretts and Esophageal Adenocarcinoma Consortium (BEACON) identified risk loci for BE and esophageal adenocarcinoma near CRTC1 and BARX1, and within 100 kb of FOXP1. We aimed to identify further SNPs that increased BE risk and to validate previously reported associations.We performed a genome-wide association study (GWAS) to identify variants associated with BE and further analyzed promising variants identified by BEACON by genotyping 10,158 patients with BE and 21,062 controls.We identified 2 SNPs not previously associated with BE: rs3072 (2p24.1; odds ratio [OR] = 1.14; 95% CI: 1.09-1.18; P = 1.8 × 10(-11)) and rs2701108 (12q24.21; OR = 0.90; 95% CI: 0.86-0.93; P = 7.5 × 10(-9)). The closest protein-coding
Barretts esophagus (BE) is a preneoplastic condition in which normal esophageal squamous epithelium (SQ) is replaced by specialized intestinal metaplasia. It is the presumed precursor for esophageal adenocarcinoma (EAC) as well as the strongest risk factor for this cancer. Unfortunately, many patients with BE go undiagnosed under the current BE screening guidelines. The development of noninvasive and accurate BE detection assays could potentially identify many of these undiagnosed BE patients.. DNA methylation is a common epigenetic alteration in BE. Therefore, we conducted a genome-wide methylation screen to identify potential BE biomarkers. Samples from SQ (N = 12), stomach (N = 28), and BE (N = 29) were analyzed and methylation levels at over 485,000 CpG sites were compared. Pyrosequencing assays were used to validate the results and MethyLight assays were developed to detect the methylated alleles in endoscopic brushings.. We discovered two genes, B3GAT2 and ZNF793, that are aberrantly ...

The oesophagus (gullet) is a muscular tube that helps channel food from the mouth to the stomach. The stomach makes acid and enzymes to help digest food. Between the oesophagus and stomach a valve prevents acid, bile and other stomach contents from refluxing back into the oesophagus. About 20% of individuals have gastro-oesophageal reflux disease (GORD) where this valve is weak and fluid including acid and bile refluxes back onto the oesophagus causing regular disruptive heartburn, an acidic taste or disruption to the oesophagus lining and scarring.. About 1 in 50 of the general population or 1 in 8 "refluxers", get a gradual change in the lining cells of the lower oesophagus called Barretts oesophagus. The usual microscopic "white tiles," change to microscopic specialised "red bricks." These specialised "bricks" produce mucus which may be a clever way of the oesophagus protecting itself against the daily damage from acid and bile refluxing back up from the stomach. Most of people cant feel ...

Endoscopic mucosal resection (EMR) is another treatment for Barretts esophagus with dysplasia.. EMR can be used to remove small nodules and lesions or to remove flat-appearing BE. The pieces removed are 15-20 mm in size, compared to regular esophageal biopsies, which are about 3-4 mm in size. EMR can be used to take out one piece of mucosa at a time (like a single nodule). Multiple EMRs can also be done in one area to resect a larger area of mucosa (like a flat area known to have a lot of HGD). In some centers, larger areas of BE (think 3 cm or larger pieces) have been removed, also called en bloc resection or total endoscopic resection. In the US, EMR is often used with other techniques (such as ablation) for management of BE with dysplasia.. There are several methods used to perform EMR. Here are a few:. Band mucosectomy - a small plastic cap is placed on the tip of the endoscope. The lining of the esophagus is sucked into the cap and a small rubber band is placed around the tissue. The ...
Background: Important risk factors for esophageal adenocarcinoma and its precursor, Barretts esophagus, include gastroesophageal reflux disease, obesity, and cigarette smoking. Recently, genome-wide association studies have identified seven germline single-nucleotide polymorphisms (SNP) that are associated with risk of Barretts esophagus and esophageal adenocarcinoma. Whether these genetic susceptibility loci modify previously identified exposure-disease associations is unclear.. Methods: We analyzed exposure and genotype data from the BEACON Consortium discovery phase GWAS, which included 1,516 esophageal adenocarcinoma case patients, 2,416 Barretts esophagus case patients, and 2,187 control participants. We examined the seven newly identified susceptibility SNPs for interactions with body mass index, smoking status, and report of weekly heartburn or reflux. Logistic regression models were used to estimate ORs for these risk factors stratified by SNP genotype, separately for Barretts ...
Barretts esophagus is when the normal cells that line your food pipe (esophagus) turn into cells not usually found in your body. The new cells take over because the lining of the esophagus has been damaged. The new, abnormal cells are called specialized columnar cells.
The dietary inflammatory index (DIITM) is a novel composite score based on a range of nutrients and foods known to be associated with inflammation. DII scores have been linked to the risk of a number of cancers, including oesophageal squamous cell cancer and oesophageal adenocarcinoma (OAC). Given that OAC stems from acid reflux and that the oesophageal epithelium undergoes a metaplasia-dysplasia transition from the resulting inflammation, it is plausible that a high DII score (indicating a pro-inflammatory diet) may exacerbate risk of OAC and its precursor conditions. The aim of this analytical study was to explore the association between energy-adjusted dietary inflammatory index (E-DIITM) in relation to risk of reflux oesophagitis, Barretts oesophagus and OAC. Between 2002 and 2005, reflux oesophagitis (n 219), Barretts oesophagus (n 220) and OAC (n 224) patients, and population-based controls (n 256), were recruited to the Factors influencing the Barretts Adenocarcinoma Relationship study ...

Radiofrequency ablation is an effective treatment for dysplasia in people with Barretts esophagus, a condition that can lead to deadly gastrointestinal cancer
FRIDAY, Jan. 19, 2018 (HealthDay News) -- A pill-sized device that you swallow might help detect a change in the esophagus that can lead to a deadly form of cancer, researchers are reporting.. The esophagus is the tube that carries food from your mouth to your stomach. And the change that occurs in the esophagus, known as Barretts esophagus, usually results from long-term reflux. Barretts esophagus is considered a precursor to a type of cancer called esophageal adenocarcinoma. More than 80 percent of people diagnosed with this cancer die within five years. Yet, medical experts say that many of these deaths could be prevented if people were diagnosed earlier with Barretts esophagus. However, that usually requires a costly and invasive test, known as an endoscopy, that also requires sedation. According to the researchers, this prevents some people from being screened for the condition.. Screening with the new device could one day change that, the authors of the new study suggest.. "Our goal is ...

When new patients call Christine Karlsens office, theyre often shaking. Theyve just been diagnosed with Barretts esophagus, a disease that can become cancer. Working on the front lines, hers is the voice patients first hear when they call the center; the face they see at every treatment.. When they call, theyre extremely scared and think theyre going to get cancer, said Karlsen, a clinical coordinator in Dr. Brian Reids lab, which runs the Seattle Barretts Esophagus Program. Its my job to talk them down from the ceiling.. Cancer risk. Barretts esophagus is a precancerous condition in the lining of the esophagus, the tube that runs from the mouth to the stomach. It typically hits 10 percent to 20 percent of middle-aged white men who have a history of chronic heartburn or indigestion. People with Barretts have a 35 percent higher chance of getting cancer than the general population, but the overall risk is small - theres only an estimated 8,000 cases diagnosed in the United States ...

Scientists working at the Medical Research Council have identified changes in the patterns of sugar molecules that line pre-cancerous cells in the esophagus, a condition called Barretts dysplasia, making it much easier to detect and remove these cells before they develop into esophageal cancer. These findings, reported in the journal Nature Medicine, have important implications for patients and may help to monitor their condition and prevent the development of cancer.. Oesophageal cancer is the fifth biggest cause of cancer death in the United Kingdom and the eighth leading cause of cancer deaths for men in the United States. Moreover, the number of people diagnosed with this disease is increasing rapidly. Individuals with a pre-cancerous condition known as Barretts oesophagus are at an increased risk of developing esophageal cancer, and need to be closely monitored to make sure that the disease is not progressing.. Dysplasia offers a stage at which cancer can be prevented by removing these ...
Chan added: "Early diagnosis and optimal treatment are important. Untreated, GERD can lead to more serious health problems such as erosive esophagitis and Barretts esophagus.". Erosive esophagitis develops when the esophagus is irritated and damaged by continued exposure to stomach acid. Barretts esophagus is a serious complication of chronic GERD involving changes in the normal tissue lining the esophagus, which can increase the risk for cancer of the esophagus.. GERD treatment involves lifestyle changes and medications; when neither of these treatment options works, surgery is the last recourse.. Lifestyle changes. Among the lifestyle changes are quitting smoking, avoiding foods and beverages that worsen symptoms, losing weight if needed, eating small frequent meals, wearing loose-fitting clothes, avoiding lying down for 3 hours after a meal and raising the head of the bed 6 to 8 inches by securing wood blocks under the bedposts. Common foods and beverages that can worsen symptoms include ...

Patients with esophageal high grade dysplasia or mucosal esophageal cancer can he successfully treated hy endoscopy. We performed a systematic review of the literature to determine whether endoscopic ultrasound (EUS) correctly predicts the T-stage of early esophageal cancers, compared with pathology specimens obtained by using endoscopic mucosal resection (EMR) or surgery. METHODS: Standard systematic review methods were used w perform reference searches, determine eligibility, abstract data, and analyze data. \When possible, individual patient-level data were abstracted, in addition to publication- level aggregate data. RESULTS: Twelve studies had sufficient information to abstract and review for quality; 8 had individual patient-level data (n = 132). Compared with surgical or EMR pathology staging, EUS had T-stage concordance of 65%, including all studies (n = 12), but only 56% concordance when limited to individual patient-level data. Factors such as initial biopsy pathology (high-grade dysplasia vs
Recent rapid increases in the incidence of oesophageal adenocarcinoma and Barretts metaplasia in western populations have led to a number of large-scale studies seeking to identify the causes of these conditions. Two of the largest and most comprehensive studies have been conducted in Australia. These studies have confirmed the long-standing clinical impression that gastro-oesophageal acid regurgitation is the principal cause of these diseases, and identified a number of other factors either positively (smoking, obesity) or negatively (H pylori infection, NSAIDs) associated with risk. Of these latter factors, it is the role of central obesity that has garnered most attention, since this may explain the five-fold higher incidence of this cancer amongst males compared with females. Genetic factors remain largely unexplored, although this will soon be rectified when the international Barretts Oesophagus and Adenocarcinoma Consortium (BEACON) completes their genome-wide association study in ...
Over the last years, array and mass spectrometry technologies have enabled analysis of the transcriptome and proteome of Barretts esophagus compared with its surrounding epithelia ( 16, 17, 27, 28). This information will be of significant value to the elucidation of molecular mechanisms that govern esophageal cell physiology and differentiation. However, an equally, if not more, important goal is to define those proteins that contribute in signaling pathways that participate in the development of Barretts esophagus and provides critical information for understanding this premalignant condition ( 19). Enzymes that phosphorylate tyrosine, serine, and threonine residues on other proteins play a major role in signaling cascades that determine cell cycle entry, survival, and the differentiation fate of cells in the mammalian body, including the gastrointestinal tract. Traditional genetic and biochemical approaches can provide some of these answers; however, for technical and practical reasons, ...
Staging of early oesophageal cancers allows the stratification of patients according to subsequent lymph node metastatic risk and allows appropriate local modalities of treatment to be offered. Once a tumour involves regional nodes or distant metastases, local treatment with endoscopic intervention is no longer a curative option. It is therefore imperative in patients with Barretts dysplasia or early OAC that treatment is offered when there is still curative intent. The depth of the cancer is correlated with the risk of lymph node metastases.14. IMC also known as a T1a cancer carries a 1.3% risk of lymph node metastasis,15 whereas the risk with submucosal T1b cancer is related to the depth of invasion;16 with SM1 carrying a 6% risk, SM2 a 23% risk and SM3 a 58% risk.17. Further risk factors for lymph node involvement include histological evidence of poorly differentiated tumour grade and lymphovascular invasion.17 Due to this risk of nodal disease, only LGD, HGD and tumours staged as T1a, or ...
