Barrett and treatment high grade dysplasia

BACKGROUND AND STUDY AIMS: This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection for Barrett's neoplasia recurrence after radiofrequency ablation. PATIENTS AND METHODS: Data from patients at sixteen centers were collected for a multicentric retrospective study. Patients who underwent at least one RFA treatment for Barrett's esophagus and thereafter underwent further esophageal ESD for neoplasia recurrence were included. RESULTS: Data from 56 patients treated by salvage ESD performed between April 2014 and November 2022 were collected...

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is a well-established treatment for Barrett's esophagus (BE) in the United States. Similarly, endoscopic submucosal dissection (ESD) has been widely performed for early esophageal carcinoma. However, conducting ESD after RFA can be technically challenging. Therefore, this study aimed to assess the feasibility and safety of ESD in patients with prior RFA. METHODS: We performed a single-center retrospective analysis of patients who underwent esophageal ESD after undergoing prior RFA treatment for BE...

Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC), and is caused by chronic gastroesophageal reflux. BE can progress over time from metaplasia to dysplasia, and eventually to EAC. EAC is associated with a poor prognosis, often due to advanced disease at the time of diagnosis. However, if BE is diagnosed early, pharmacologic and endoscopic treatments can prevent progression to EAC. The current standard of care for BE surveillance utilizes the Seattle protocol. Unfortunately, a sizable proportion of early EAC and BE-related high-grade dysplasia (HGD) are missed due to poor adherence to the Seattle protocol and sampling errors...

PURPOSE: The objective of this scoping review is to understand the extent, type of evidence, and overall findings in relation to the impact of endoscopic treatment (ET) on health-related quality of life (HR-QoL) in patients with Barrett's dysplasia and early oesophageal cancer. METHODS: A comprehensive search was conducted for literature between 2001 and 2022 in computerised databases (PubMed, Embase, Cochrane Library, and CINAHL Complete). Additionally, sources of unpublished literature were searched in Google Advanced Search...

Barrett's oesophagus is a pathological condition whereby the normal oesophageal squamous mucosa is replaced by specialised, intestinal-type metaplasia, which is strongly linked to chronic gastro-oesophageal reflux. A correct endoscopic and histological diagnosis is pivotal in the management of Barrett's oesophagus to identify patients who are at high risk of progression to neoplasia. The presence and grade of dysplasia and the characteristics of visible lesions within the mucosa of Barrett's oesophagus are both important to guide the most appropriate endoscopic therapy...

MR1 : ESGE recommends the following standards for Barrett esophagus (BE) surveillance:- a minimum of 1-minute inspection time per cm of BE length during a surveillance endoscopy- photodocumentation of landmarks, the BE segment including one picture per cm of BE length, and the esophagogastric junction in retroflexed position, and any visible lesions- use of the Prague and (for visible lesions) Paris classification- collection of biopsies from all visible abnormalities (if present), followed by random four-quadrant biopsies for every 2-cm BE length...

INTRODUCTION: Barrett's esophagus (BE) is a precursor to esophageal adenocarcinoma. Physicians infrequently adhere to guidelines for managing BE, leading to either reduced detection of dysplasia or inappropriate re-evaluation. METHODS: We conducted a three-arm randomized controlled trial with 2 intervention arms to determine the impact of a tissue systems pathology (TSP-9) test on the adherence to evidence-based guidelines for simulated patients with BE. Intervention 1 received TSP-9 results, and intervention 2 had the option to order TSP-9 results...

BACKGROUND: Barrett's esophagus (BE) is a premalignant condition to esophageal adenocarcinoma (EAC). Low socioeconomic (SES) status adversely impacts care and outcomes in patients with EAC, but this has not been evaluated in BE. As the treatment of BE is similarly intensive, we aimed to evaluate the effect of SES on achieving complete eradication of intestinal metaplasia (CE-IM), dysplasia (CE-D) and development of invasive EAC. METHODS: Our study was a retrospective cohort study...

BACKGROUND AND AIMS: Endoscopic eradication therapy (EET) is guideline endorsed for management of early-stage (T1) esophageal adenocarcinoma (EAC). Patients with baseline high grade dysplasia (HGD) and EAC are at highest risk of recurrence following successful EET, but limited data exist on long-term (> 5 year) recurrence outcomes. We aimed to assess the incidence and predictors of long-term recurrence in a multicenter cohort of T1EAC patients treated with EET. METHODS: Patients with T1 EAC achieving successful endoscopic cancer eradication with a minimum of 5-years clinical follow-up were included...

PURPOSE OF REVIEW: Endoscopic eradication therapy is an effective and durable treatment for Barrett's esophagus (BE) related neoplasia, but even after achieving successful eradication, these patients remain at risk for recurrence and require ongoing routine examinations. The optimal surveillance protocol including endoscopic technique, sampling strategy, and timing are still being refined. The aim of this review is to discuss current management principles for the post ablation patient and emerging technologies to guide clinical practice...

INTRODUCTION: Esophageal adenocarcinoma incidence has increased significantly despite surveillance endoscopy for Barrett's esophagus (BE) and gastric acid supression medications. This prospective, cohort study's aims were to determine the long-term efficacy of proton-pump inhibitors twice daily (PPI-BID) with cryotherapy (CRYO) for complete ablation of BE. MATERIALS AND METHODS: Consecutive BE patients were managed with a PPI-BID, CRYO ablation, follow-up protocol...

PURPOSE: Clinical guidelines recommend radiofrequency ablation (RFA) for eradication of Barrett esophagus in patients with low-grade dysplasia (LGD) and high-grade dysplasia (HGD), but evidence on whether RFA provides good value for money is still sparse. This study evaluates the cost-effectiveness of RFA in Italy. METHODS: A Markov model was used to estimate lifelong costs and consequences of disease progression with different treatments. RFA was compared with esophagectomy in the HGD group or endoscopic surveillance in the LGD group...

Oncogene amplification on extrachromosomal DNA (ecDNA) drives the evolution of tumours and their resistance to treatment, and is associated with poor outcomes for patients with cancer1-6 . At present, it is unclear whether ecDNA is a later manifestation of genomic instability, or whether it can be an early event in the transition from dysplasia to cancer. Here, to better understand the development of ecDNA, we analysed whole-genome sequencing (WGS) data from patients with oesophageal ademocarcinoma (EAC) or Barrett's oesophagus...

BACKGROUND AND OBJECTIVE: Barrett's esophagus (BE) is associated with an increased risk of esophageal adenocarcinoma. The use of radio frequency ablation (RFA) for complete eradication of BE with confirmed low-grade dysplasia (LGD) or high-grade dysplasia (HGD) has been promising in multicenter trials. Our aim was to evaluate the safety and efficacy outcomes associated with RFA for patients with BE and LGD/HGD in a single-center setting. METHODS: This was a retrospective single-center study conducted at Department of Surgery and Transplantation, Rigshospitalet, Denmark...

Barrett's esophagus has been an important issue in clinical medicine for many years. In the 70 s of the last century, the association between gastroesophageal reflux disease and BE was detected. Only ten years later, the association between BE and adenocarcinoma of the esophagus was reported. Starting in the 90s in Europe, endoscopic resection and ablation have seen an expanding role in the management of BE. In analogy with other diseases, patients are undergoing individualized surveillance and treatment strategies...

The poor prognosis of patients with esophageal cancer leads to the constant search for new ways of treatment of this disease. One of the methods used in high-grade dysplasia, superficial invasive carcinoma, and sometimes palliative care is photodynamic therapy (PDT). This method has come a long way from the first experimental studies to registration in the treatment of esophageal cancer and is constantly being improved and refined. This review describes esophageal cancer, current treatment methods, the introduction to PDT, the photosensitizers (PSs) used in esophageal carcinoma PDT, PDT in squamous cell carcinoma (SCC) of the esophagus, and PDT in invasive adenocarcinoma of the esophagus...

Previous studies on fear of cancer recurrence after endoscopic treatment for early Barrett's neoplasia focused on fear during a relatively short period after the intervention. The aim of this study was to explore whether fear of cancer (recurrence) persists during long-term follow-up in patients treated endoscopically for Barrett's neoplasia compared to patients treated surgically for a more advanced stage of esophageal adenocarcinoma. Participants previously participated in a prospective longitudinal study investigating quality of life and fear of cancer recurrence and were treated endoscopically for early Barrett's neoplasia (high-grade dysplasia-T1sm1N0M0) or surgically for a more advanced esophageal adenocarcinoma (T1N0M0-T3N1M0)...

Background and study aims  Barrett's esophagus (BE) is a precursor condition to esophageal adenocarcinoma (EAC), resulting in transformation of the squamous epithelium of distal esophagus to columnar-lined epithelium with intestinal metaplasia (IM). Liquid nitrogen spray cryotherapy (LNSC) is a non-contact method of BE eradication and has been used both as primary and salvage therapy. We conducted a systematic review and meta-analysis to assess the safety and efficacy of LNSC. Methods  We searched multiple databases from inception through December 2021 to identify studies on use of LNSC for Barrett's neoplasia...

BACKGROUND: Esophageal endoscopic submucosal dissection (ESD) is the gold standard for the treatment of precancerous lesions or superficial esophageal cancers. This procedure is currently performed by expert endoscopists only, and poorly standardized. We aimed to assess the technical results and outcomes of a "tunnel + clip" strategy for esophageal ESD procedures performed by less experienced operators for the treatment of superficial neoplasms. METHODS: All consecutive esophageal ESDs performed with the "tunnel + clip" technique for patients with early esophageal cancer in 3 centers were enrolled...

While patients with Barrett's esophagus without dysplasia may benefit from endoscopic surveillance, those with low-grade dysplasia may be managed with either endoscopic surveillance or endoscopic eradication. Patients with Barrett's esophagus with high-grade dysplasia and/or intramucosal adenocarcinoma will generally require endoscopic eradication therapy. The management of Barrett's esophagus with dysplasia and early esophageal adenocarcinoma is predominantly endoscopic, with multiple effective methods available for the resection of raised neoplasia and ablation of flat neoplasia...
