Some observations on Barrett esophagus and associated dysplasia.

Biopsy samples from esophageal columnar metaplasia and dysplasia are commonly encountered in Western pathology practice and knowing a few pitfalls can save both pathologists and patients a great deal of anxiety. Herein we discuss criteria for Barrett esophagus, evaluation of dysplasia, and some pitfalls in reviewing endoscopic mucosal resections. Also included is a summary of suggested follow-up for patients with Barrett esophagus.


Endoscopic Treatment of Early Barrett's Adenocarcinoma and Dysplasia: Focus on Submucosal Cancer.

Eradication of early Barrett's neoplasia by endoscopic resection and radiofrequency ablation is safe and effective. In T1b adenocarcinoma, standard of care remains controversial. We investigated the therapeutic outcome between high-grade dysplasia (HGD)/mucosal adenocarcinoma and submucosal adenocarcinoma in Barrett's patients. We hypothesised similar outcome in low-risk (LR) T1b compared to T1a/HGD.

Multifocal nitrous oxide cryoballoon ablation with or without EMR for treatment of neoplastic Barrett's esophagus.

Endoscopic cryotherapy can eradicate neoplastic Barrett's esophagus (BE). A new contact cryoballoon focal ablation system (CbFAS)) freezes esophageal mucosa with nitrous oxide. We studied the safety and efficacy of CbFAS for complete eradication of neoplastic Barrett's esophagus.


Association of Vitamin D and Parathyroid Hormone With Barrett's Esophagus.

Esophageal adenocarcinoma has been inversely associated with exposure to ultraviolet radiation. This could be because of vitamin D deficiency or hyperparathyroidism promoting gastroesophageal reflux disease (GERD) and Barrett's esophagus.

Mucosal Ablation in Patients with Barrett's Esophagus: Fry or Freeze?

The management of Barrett's esophagus and early esophageal adenocarcinoma has shifted away from esophagectomy and toward endoscopic techniques, including endoscopic resection and ablative therapies. The most commonly used ablative therapies are radiofrequency ablation and cryotherapy. Radiofrequency ablation has risen to the top of the management algorithm due to its favorable safety profile and established track record of efficacy in patients with dysplastic Barrett's. Cryotherapy offers early promise as a...

A review of the incidence of adenocarcinoma detected during surveillance for Barrett's esophagus.

The objective of this study is to provide an up to date estimate of the incidence of adenocarcinoma detected during surveillance of Barrett's esophagus. Fifty-five longitudinal studies involving approximately 61000 patients were reviewed. A general linear model analyses with Poisson link function was used to study how the number of cancer cases detected depended on study details. The studies appeared to follow the same statistical model, and the probability of developing Barrett's carcinoma during surveilla...

Microsatellite instability in metaplasia-dysplasia-adenocarcinoma sequence of Barrett esophagus: a retrospective study.

To analyze the loss of mismatch repair (MMR) system protein expression in metaplasia-dysplasia-adenocarcinoma sequence of Barrett esophagus (BE).

Selection and Application of Tissue microRNAs for Non-endoscopic Diagnosis of Barrett's Esophagus.

MicroRNA (miRNA) is highly stable in biospecimens and provides tissue-specific profiles, making it a useful biomarker of carcinogenesis. We aimed to discover a set of miRNAs that could accurately discriminate Barrett's esophagus (BE) from normal esophageal tissue and to test its diagnostic accuracy when applied to samples collected by a non-invasive esophageal cell sampling device.

Acceptability, Accuracy and Safety of Disposable Transnasal Capsule Endoscopy for Barrett's Esophagus Screening.

Screening for Barrett's esophagus (BE) with conventional esophagogastroduodenoscopy (C-EGD) is expensive. We assessed the performance of a clinic-based, single use transnasal capsule endoscope (EG Scan II) for the detection of BE, compared to C-EGD as the reference standard.

Detection of Mutations in Barrett's Esophagus Before Progression to High-grade Dysplasia or Adenocarcinoma.

Barrett's esophagus (BE) is the greatest risk factor for esophageal adenocarcinoma, but only a small proportion of patients with BE develop cancer. Biomarkers might be able to identify patients at highest risk of progression. We investigated genomic differences in surveillance biopsies collected from patients whose BE subsequently progressed compared to patients whose disease did not progress.

Can endoscopic resection for Barrett's dysplasia and early cancer be curative?

Effective endoscopic treatments for dysplasia and early (intramucosal) cancer, together with expanded and rigorous screening programs to detect Barrett's esophagus, could help reverse the increase in the incidence of esophageal cancer and reduce esophageal cancer-related mortality. In this review, we discuss the long-term outcomes for mucosal resection for dysplasia and early cancer and compares them to esophagectomy as the standard of care choice. Eendoscopic resection for Barrett's dysplasia and early can...

Differences of risk factors and clinical presentations in male and female Taiwanese individuals with Barrett's esophagus.

Barrett's esophagus (BE) is a disorder more often found in obese men. Differences between the two genders are not known in the Asian countries. Here, we studied their gender differences in the Taiwanese population in terms of risk factors and clinical presentations.

Inter-institutional variations regarding Barrett's esophagus diagnosis.

Barrett's esophagus (BE) is a known precursor for development of esophageal adenocarcinoma and surveillance of affected patients is necessary when cancer progression risk is considered to be high. However, the accuracy of BE diagnosis may not be homogenous among institutions with endoscopy units. We investigated inter-institutional variability by examining the accuracy of endoscopic diagnosis of BE at 4 different hospitals.

Factors Associated With Recurrence of Barrett's Esophagus After Radiofrequency Ablation.

Radiofrequency ablation (RFA) is effective treatment for Barrett's esophagus (BE). However, some patients have recurrence after complete eradication of intestinal metaplasia (CEIM). We investigated the incidence of and factors associated with BE recurrence, with or without neoplasia, after RFA and CEIM using data from the national Veterans Affairs (VA) healthcare system.

Buried Barrett's Esophagus with High-Grade Dysplasia after Radiofrequency Ablation.

Radiofrequency ablation therapy is an effective endoscopic option for the eradication of Barrett's esophagus that appears to reduce the risk of esophageal cancer. A concern associated with this technique is the development of subsquamous/buried intestinal metaplasia, whose clinical relevance and malignant potential have not yet been fully elucidated. Fewer than 20 cases of subsquamous neoplasia after the successful radiofrequency ablation of Barrett's esophagus have been reported to date. Here, we describe ...

Barrett Esophagus Length, Nodularity, and Low-grade Dysplasia are Predictive of Progression to Esophageal Adenocarcinoma.

To investigate factors predictive of progression from nondysplastic Barrett esophagus (NDBE) or low-grade dysplasia (LGD) to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) using a large, prospective cohort of patients, wherein all esophageal biopsies undergo expert gastrointestinal pathologist review.

Development of Evidence Based Surveillance Intervals following Radiofrequency Ablation of Barrett's Esophagus.

Barrett's esophagus (BE) recurs in 25% or more of patients treated successfully with radiofrequency ablation (RFA), so surveillance endoscopy is recommended after complete eradication of intestinal metaplasia (CEIM). The frequency of surveillance is informed only by expert opinion. We aimed to model the incidence of neoplastic recurrence, validate the model in an independent cohort, and propose evidence-based surveillance intervals.

Screening for Barrett's Esophagus: Are New High-Volume Methods Feasible?

New improved methods are required for the early detection of esophageal adenocarcinoma in order to reduce mortality from this aggressive cancer. In this review we discuss different screening methods which are currently under evaluation ranging from image-based methods to cell collection devices coupled with biomarkers. As Barrett's esophagus is a low prevalence disease, potential screening tests must be applied to an enriched population to reduce the false-positive rate and improve the cost-effectiveness of...

Increasing prevalence of high-grade dysplasia and adenocarcinoma on index endoscopy in Barrett's esophagus over the past 2 decades: data from a multicenter U.S. consortium.

Data on time trends of dysplasia and esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) during the index endoscopy (ie, prevalent cases) are limited. Our aim was to determine the prevalence patterns of BE associated dysplasia on index endoscopy over the past 25 years.

Esophageal adenocarcinoma in Barrett's esophagus after sleeve gastrectomy: Case report and literature review.

Sleeve gastrectomy (SG) has become one of the most dramatically increasing bariatric procedures worldwide due to its excellent results and impact on the obesity pandemic. Morbid obesity is known to increase the risk of esophageal adenocarcinoma. However, the evolution of gastroesophageal reflux disease (GERD) along with Barrett's esophagus (BE) after SG is of concern since there is little data available. We present a case of esophageal adenocarcinoma after SG with known intestinal metaplasia on preoperative...

Global Climate Change and the "So What?" Issue: Reversing the Impact of Donald Trump.

Preclinical models for the study of Barrett's carcinogenesis.

Barrett's esophagus (BE) is clinically significant, as it is the only known precursor lesion for esophageal adenocarcinoma. To develop improved therapies for the treatment of BE, a greater understanding of the disease process at the molecular genetic level is needed. However, achieving a greater understanding will require improved preclinical models so that the disease process can be more closely studied and novel therapies can be tested. Our concise review highlights progress in the development of preclini...
