Gastroenterology society guidelines recommend endoscopic surveillance as a means to detect early stage cancer in Barrett's esophagus. However, the incidence of esophageal adenocarcinoma in Western countries continues to increase, suggesting that this strategy may be inadequate. Current surveillance methods rely on the endoscopist's ability to identify suspicious areas of Barrett's esophagus to biopsy, random biopsies, and on the histopathologic diagnosis of dysplasia. This review highlights the challenges of using dysplasia to stratify cancer risk and addresses the development and use of molecular biomarkers and in vivo molecular imaging to detect early neoplasia in Barrett's esophagus...

Guidelines for the screening and surveillance of Barrett's esophagus continue to evolve as the incidence of esophageal adenocarcinoma increases, identification of individuals at highest risk for cancer improves, and management of dysplasia evolves. This article reviews related studies and economic analyses. Advances in diagnosis offer promising strategies to help focus screening efforts on those individuals who are most likely to develop esophageal adenocarcinoma.

Barrett's esophagus (BE) predisposes patients to esophageal adenocarcinoma. 3 to 6% of individuals with gastro-esophageal reflux disease are estimated to have BE but only 20 to 25% of BE patients are currently diagnosed. The current gold standard for diagnosis of BE is per-oral upper GI endoscopy. As this is not suitable for large-scale screening, a number of alternative methods are currently being investigated: transnasal and video capsule endoscopy, endomicroscopy, cell collection devices like the cytosponge and biomarkers...

Multimodal endoscopy using fluorescence molecular probes is a promising method of surveying the entire esophagus to detect cancer progression. Using the fluorescence ratio of a target compared to a surrounding background, a quantitative value is diagnostic for progression from Barrett's esophagus to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC). However, current quantification of fluorescent images is done only after the endoscopic procedure. We developed a Chan-Vese-based algorithm to segment fluorescence targets, and subsequent morphological operations to generate background, thus calculating target/background (T/B) ratios, potentially to provide real-time guidance for biopsy and endoscopic therapy...

Low-grade dysplasia in Barrett esophagus remains an ongoing challenge in clinical management. Recent studies suggest an increased risk in progression of low-grade dysplasia to high-grade dysplasia and/or adenocarcinoma. This is especially seen when 1 or more expert gastrointestinal pathologist confirms the diagnosis and in the setting of low-grade dysplasia that persists on more than 1 endoscopy. In the setting of confirmed and persistent low-grade dysplasia, level 1 evidence supports endoscopic ablation as a treatment option for these patients, although continued surveillance remains a viable option...

Barrett esophagus (BE) is a precursor lesion for esophageal adenocarcinoma (EAC). Developments in imaging and molecular markers, and endoscopic eradication therapy, are available to curb the increase of EAC. Endoscopic surveillance is recommended, despite lack of data. The cancer risk gets progressively downgraded, raising questions about the understanding of risk factors and molecular biology involved. Recent data point to at least 2 carcinogenic pathways operating in EAC. The use of p53 overexpression and high-risk human papillomavirus may represent the best chance to detect progressors...

Barrett's esophagus (BE) is a premalignant condition associated with the development of esophageal adenocarcinoma (EAC). Despite the low risk of progression to EAC, evidence highlights the notably poor survival rates of this malignancy. The mainstay form of diagnosis of BE is endoscopy and biopsy sampling. However, research emphasizes limitations with regards to the histological detection of BE and associated dysplasia. The aim of this study is to evaluate the clinical significance of CEACAM6 as a potential biomarker for the diagnosis of BE and beyond...

BACKGROUND: Endoscopic management of Barrett's esophagus (BE) depends on the histological stage of BE and includes the following: follow up, endotherapy with thermal ablation, and piecemeal or monobloc endoscopic resection (ER). We know that biopsies are unreliable in 20-75% of cases. The aim of our study was to evaluate the efficiency of probe confocal laser endomicroscopy (pCLE) in the diagnosis of the histological stage of BE, compared with the final histological results after ER. METHODS: This retrospective study was based on a prospective registry of patients referred for management of BE-associated dysplasia...

The incidence of Barrett's esophagus (BE) in the Western world has increased over the last decades. BE is considered a premalignant lesion that can progress to esophageal adenocarcinoma (EAC), a highly aggressive malignancy with poor survival rates. The close association between BE and EAC highlights the need for an early diagnosis in order to improve survival and outcomes in this group of patients. Although the evidence for BE screening with conventional endoscopy is controversial and limited by cost-effectiveness studies, screening can be suggested in patients with chronic gastroesophageal reflux disease (GERD) and two or more risk factors for EAC...

Esophagogastric landmarks are recognizable in the same way both in children and in adults, and palisade-shaped vessels can be observed at the distal position of esophageal mucosa, even in infants. Few studies have been done in respect to Barrett's esophagus (BE) in children. Incidence of endoscopically suspected BE among all children undergoing esophagogastroduodenoscopy (EGD) is approximately 0.25-1.4%, but can be up to 9.7% in patients with gastroesophageal reflux disease (GERD). Some data suggest that BE is an acquired disorder and point to the possibility of a congenital component in combination with severe mucosal injury...

OBJECTIVES: Endoscopic surveillance of patients with Barrett's Esophagus (BE) is recommended to detect esophageal adenocarcinoma (EAC) and its dysplasia precursors, but survival benefits are unclear. Using Surveillance, Epidemiology, and End Results (SEER) and linked Medicare data, we sought to determine the impact of a prior BE diagnosis on survival in patients with EAC. METHODS: Our analysis focused on patients over age 65 with primary EAC diagnosed in a SEER region from 2000-2011 and enrolled in Medicare...

BACKGROUND AND AIMS: Preliminary single-institution data suggest that fluorescence in situ hybridization (FISH) may be useful for detecting high-grade dysplasia (HGD) and esophageal adenocarcinoma (EA) in patients with Barrett's esophagus (BE). This multicenter study aims to validate the measurement of polysomy (gain of at least two loci) by FISH as a way to discriminate degrees of dysplasia in BE specimens. METHODS: Tissue specimens were collected from four different hospitals and read by both the local pathology department ("Site diagnosis") and a single central pathologist ("Review diagnosis") at a separate institution...

BACKGROUND The pathological mechanism of Barrett's esophagus (BE) is still unclear. In the present study, pathway cross-talks were analyzed to identify hub pathways for BE, with the purpose of finding an efficient and cost-effective detection method to discover BE at its early stage and take steps to prevent its progression. MATERIAL AND METHODS We collected and preprocessed gene expression profile data, original pathway data, and protein-protein interaction (PPI) data. Then, we constructed a background pathway cross-talk network (BPCN) based on the original pathway data and PPI data, and a disease pathway cross-talk network (DPCN) based on the differential pathways between the PPI data and the BE and normal control...

Barrett esophagus (BE) is a known risk factor for the development of esophageal adenocarcinoma. Pathologists play a critical role in confirming the diagnosis of BE and BE-associated dysplasia. As these diagnoses are not always straightforward on routine hematoxylin and eosin-stained slides, numerous ancillary stains have been used in an attempt to help pathologists confirm the diagnosis. On the basis of an in-depth review of the literature, the Rodger C. Haggitt Gastrointestinal Pathology Society provides recommendations regarding the use of ancillary stains in the diagnosis of BE and BE-associated dysplasia...
