Barrett and treatment high grade dysplasia

Dan Li, Jie Hong, Weibiao Cao
We have shown that NOX5-S may mediate the acid-induced decrease in cell apoptosis. However, mechanisms of NOX5-S-dependent decrease in cell apoptosis are not fully understood. In this study we found that silencer of death domain (SODD) was significantly increased in esophageal adenocarcinoma (EA) tissues, EA cell lines FLO and OE33, and a dysplastic cell line CP-B. Strong SODD immunostaining was significantly higher in low-grade dysplasia (66.7%), high-grade dysplasia (81.2%) and EA (71.2%) than in Barrett's mucosa (10...

BACKGROUND: Endoscopic resection (ER) with or without ablation is the first choice treatment for early Barrett's neoplasia. Adequate staging is important to assure a good oncological outcome. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of pre-operative biopsies in patients who undergo ER for high-grade dysplasia (HGD) or early adenocarcinoma (EAC) in Barrett's oesophagus (BE) and the cardia. METHODS: Between November 2005-May 2012, 142 ERs performed in 137 patients were obtained...

BACKGROUND: and Study Aim: The role of endoscopic submucosal dissection (ESD) in Barrett's early neoplasia is not well-defined, with most studies originating from Asia and Europe. We aimed to assess the efficacy, safety, and results of ESD in Barrett's esophagus (BE) with high-grade dysplasia (HGD) and early adenocarcinoma (EAC) across centers in the United States. METHODS: Multicenter retrospective analysis on 46 patients with BE who underwent ESD for BE-HGD and/or EAC between January 2010 and April 2015...

Approximately 10% to 15% of patients who experience chronic gastroesophageal reflux disease have Barrett esophagus, which is associated with an increased risk of esophageal adenocarcinoma. If symptoms persist after 8 weeks of adhering to treatment and lifestyle modifications, or if alarm symptoms develop, patients should be referred for screening upper endoscopy. Those with evidence of Barrett esophagus with dysplasia should be monitored in an endoscopic surveillance program, and those with high-grade dysplasia should consider surgical treatment...

The endoscopic management of Barrett's esophagus (BE) has changed with the emergence of novel endoscopic technologies and new data informing the care of dysplastic BE and early adenocarcinoma. These changes include an expanded use of endoscopic ablative therapy as well new recommendations for surveillance intervals. For most patients with BE and high-grade dysplasia (HGD), endoscopic ablative therapy is the preferred treatment strategy. Ablation has consistently been shown to be effective, with less morbidity compared with surgery...

In recent years, a number of endoluminal procedures such as endoscopic resection and thermal ablation have emerged as less invasive treatment options for early esophageal cancer. These therapies have demonstrated excellent oncologic outcomes for dysplasia as well as intramucosal cancers. However, few studies have directly compared long-term outcomes of endoscopic therapy versus traditional esophagectomy. Current esophagectomy techniques now deliver consistently good outcomes in the hands of experienced surgeons at high volume centers, and this option should be considered an important treatment consideration for early esophageal cancer...

Barrett's esophagus (BE) is a pre-malignant condition affecting up to 15% of patients with gastroesophageal reflux disease. Neoplastic Barrett's mucosa is defined as harboring high grade dysplasia or intra-mucosal cancer, and carries a high risk of progression to esophageal adenocarcinoma. The rising incidence of Barrett's lesions along with the high morbidity of surgical approaches has led to the development of numerous validated endoscopic techniques capable of eradicating neoplastic mucosa in a minimally invasive manner...

BACKGROUND AND AIMS: Endotherapy (ET) has replaced surgery as the first-line treatment of high-grade dysplasia (HGD)/superficial ECA (ECAs) from Barrett's oesophagus (BO). However, long-term follow-up and predictive factors of relapse are not so well studied. The aim of the following study was to evaluate the efficiency of ET for treatment of HGD/ECAs and to determine factors of long-term efficiency. METHODS: ET procedures were manually reported and registered in a hospital data base from March 2000 to July 2010...

BACKGROUND AND AIMS: Piecemeal endoscopic mucosal resection (EMR) is the standard treatment of nodular Barrett's esophagus dysplasia and T1a cancer. Piecemeal resection may be incomplete and makes precise histologic assessment difficult. Endoscopic submucosal dissection (ESD) is a technique that enables en-bloc resection but has not gained widespread acceptance due to its technical difficulty, risk and long procedure time. METHODS: We developed a protocol consisting of a combination of a limited ESD with supplementary EMR in the same session if necessary, designed to increase en-bloc resection of the most worrisome neoplastic area while maximizing the rate of complete resection of dysplasia...

PURPOSE OF REVIEW: The diagnosis and management of low-grade dysplasia (LGD) in Barrett's esophagus continue to evolve and vary in practice. Radiofrequency ablation (RFA) is now an acceptable option for the treatment of LGD. Therefore, the purpose of this review article is to present current literature on the diagnosis and management of LGD, and to explore when to optimally pursue RFA for the treatment of LGD. RECENT FINDINGS: The challenge of the management of LGD begins with its diagnosis...

BACKGROUND: Barrett esophagus (BE) continues to be a major risk factor for developing esophageal adenocarcinoma. METHODS: We review the risk factors, diagnosis, and management of BE, with an emphasis on the most current endoscopic diagnostic modalities for BE. RESULTS: Novel diagnostic modalities have emerged to address the inadequacies of standard, untargeted biopsies, such as dye-based and virtual chromoendoscopy, endoscopic mucosal resection, molecular biomarkers, optical coherence tomography, confocal laser endomicroscopy, volumetric laser endomicroscopy, and endocytoscopy...

OBJECTIVES: Multiple endoscopic sessions may be necessary for treatment and surveillance of Barrett's esophagus (BE)-associated neoplasia. Adherence to an endoscopic therapeutic regimen is important for longitudinal management of BE. The objective of this study was to identify the factors associated with adherence to therapy for BE-associated neoplasia. METHODS: We retrospectively identified patients with BE whom were referred to a tertiary center for endoscopic mucosal resection (EMR) or radiofrequency ablation (RFA) between 2009 and 2012...

In patients who have undergone ablation therapy for treatment of Barrett's esophagus with dysplasia, histologic features of eosinophilic esophagitis, but not lymphocytic esophagitis, have been described. We evaluated for histologic evidence of eosinophilic esophagitis and lymphocytic esophagitis and correlated with endoscopic findings in this population. A single-institution Barrett's esophagus registry was searched for patients who had received radiofrequency ablation, cryotherapy, or both for treatment of Barrett's esophagus with dysplasia...

Barrett's esophagus (BE) is a premalignant condition that is associated with the development of esophageal adenocarcinoma. Risk factors that have been associated with the development of BE include male gender, Caucasian race, chronic gastroesophageal reflux disease, smoking, age >50 and obesity. The current management of BE is dependent on underlying pathological changes and treatment can range from surveillance endoscopy with daily proton pump inhibitor (PPI) therapy in the setting of intestinal metaplasia or low-grade dysplasia (LGD) to radiofrequency ablation (RFA), endoscopic mucosal resection or surgical resection in the setting of high-grade dysplasia...

Barrett's esophagus (BE) is the most important risk factor for esophageal adenocarcinoma. Through the sequence of no dysplasia to low-grade dysplasia (LGD) and high-grade dysplasia (HGD), eventually early cancer (EC) may develop. The risk of neoplastic progression is relatively low, 0.5-0.9 % per patient per year. However, once diagnosed, esophageal adenocarcinoma is often irresectable, and 5-year survival is only 15 %. Therefore, non-dysplastic BE patients are kept under endoscopic surveillance to detect early neoplasia in a curable stage...

BACKGROUND: We present long-term follow-up data on patients with esophageal high-grade dysplasia and/or carcinoma in situ who were treated with laparoscopic transgastric esophageal mucosal resection (LTEMR). METHODS: Patient demographics, operative outcomes, and follow-up results were tabulated. RESULTS: LTEMR was performed in 11 patients (9 male, 2 female). The median age was 54 (44 to 75) years. The 30-day morbidity or mortality was zero...

BACKGROUND & AIMS: In some patients with Barrett's esophagus (BE) and a confirmed diagnosis of low-grade dysplasia (LGD), the LGD is not detected during follow-up examinations. We would like to avoid the unnecessary risks and costs of ablative treatment for these patients. Therefore, we investigated whether persistent LGD increases risk for high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and what proportion of patients are no longer found to have dysplasia after an initial diagnosis of LGD...

INTRODUCTION: Endoscopic therapy has revolutionized the treatment of Barrett's esophagus with high-grade dysplasia (HGD) or intramucosal adenocarcinoma by allowing preservation of the esophagus in many patients who would previously have had an esophagectomy. This paradigm shift initially occurred at high-volume centers in North America and Europe but now is becoming mainstream therapy. There is a lack of uniform guidelines and algorithms for the management of these patients. Our aim was to review important concepts and pitfalls in the endoscopic management of superficial esophageal adenocarcinoma...

OBJECTIVE: The purpose of this study is to determine the comparative effectiveness of esophagectomy versus endoscopic mucosal resection followed by radiofrequency ablation (EMR-RFA) for the treatment of Barrett esophagus with high-grade dysplasia (HGD). BACKGROUND: HGD of the esophagus may be managed by surgical resection or EMR-RFA. National guidelines suggest that EMR-RFA is effective at eradicating HGD. The comparative effectiveness and cost-effectiveness of EMR-RFA versus esophagectomy for HGD remains unclear...

OBJECTIVE: HALO radiofrequency ablation (RFA) has been proven as safe and efficient in eradication of both non- and dysplastic Barrett's esophagus (BE). Definitive post-RFA treatment is yet to be determined. METHODS: RFA was performed in 56 patients with BE, 38 with intestinal metaplasia (IM) and 18 with low-grade dysplasia (LGD), and repeated in case of residual BE. Length of the BE was classified according to C&M criteria. Follow-up included regular upper GI endoscopies with biopsies 6 months, 1 and 2 years after the complete resolution of BE...
