Abstract
BACKGROUND This study evaluated the safety and efficacy of salvage endoscopic submucosal dissection (ESD) for Barrett's neoplasia recurrence after radiofrequency ablation (RFA). METHODS Data from patients at 16 centers were collected for a multicenter 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 who underwent salvage ESD between April 2014 and November 2022 were collected. Immediate complications included one muscular tear (1.8%) treated with stent (Agree classification: grade IIIa). Two transmural perforations (3.6%; treated with clips) and five muscular tears (8.9%; two treated with clips) had no clinical impact and were not considered as adverse events. Seven patients (12.5%) developed strictures (grade IIIa), which were treated with balloon dilation. Histological analysis showed 36 adenocarcinoma, 17 high grade dysplasia, and 3 low grade dysplasia. En bloc and R0 resection rates were 89.3% and 66.1%, respectively. Resections were curative in 33 patients (58.9%), and noncurative in 22 patients (39.3%), including 11 "local risk" (19.6%) and 11 "high risk" (19.6%) resections. At the end of follow-up with a median time of 14 (0-75) months after salvage ESD, and with further endoscopic treatment if necessary (RFA, argon plasma coagulation, endoscopic mucosal resection, ESD), neoplasia remission ratio was 37/53 (69.8%) and the median remission time was 13 (1-75) months. CONCLUSION In expert hands, salvage ESD was a safe and effective treatment for recurrence of Barrett's neoplasia after RFA treatment.

Risk of metastasis among patients diagnosed with high-risk T1 esophageal adenocarcinoma who underwent endoscopic follow-up. Dis Esophagus 2024; 37:doae027. [PMID: 38580314 DOI: 10.1093/dote/doae027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 03/05/2024] [Accepted: 03/19/2024] [Indexed: 04/07/2024]
Abstract
Esophagectomy and lymphadenectomy have been the standard of care for patients at high risk (HR) of lymph node metastasis following a diagnosis of early esophageal adenocarcinoma (OAC) after endoscopic resection (ER). However, recent cohorts suggest lymph node metastasis risk is lower than initially estimated, suggesting organ preservation with close endoscopic follow-up is a viable option. We report on the 3- and 5-year risk of lymph node/distant metastasis among patients diagnosed with early HR-T1 OAC undergoing endoscopic follow-up. Patients diagnosed with HR-T1a or T1b OAC following ER at a tertiary referral center were identified and retrospectively analyzed from clinical records between 2010 and 2021. Patients were included if they underwent endoscopic follow-up after resection and were divided into HR-T1a, low risk (LR)-T1b and HR-T1b cohorts. After ER, 47 patients underwent endoscopic follow-up for early HR OAC. In total, 39 patients had an R0 resection with a combined 3- and 5-year risk of LN/distant metastasis of 6.9% [95% confidence interval (CI): 1.8-25] and 10.9% (95% CI, 3.6-30.2%), respectively. There was no significant difference when stratifying by histopathological subtype (P = 0.64). Among those without persistent luminal disease on follow-up, the 5-year risk was 4.1% (95% CI, 0.6-26.1). Two patients died secondary to OAC with an all-cause 5-year survival of 57.5% (95% CI, 39.5-71.9). The overall risk of LN/distant metastasis for early HR T1 OAC was lower than historically reported. Endoscopic surveillance can be a reasonable approach in highly selected patients with an R0 resection and complete luminal eradication, but clear, evidence-based surveillance guidelines are needed.

Abstract
One of the earliest applications of flow cytometry was the measurement of DNA content in cells. This method is based on the ability to stain DNA in a stoichiometric manner (i.e., the amount of stain is directly proportional to the amount of DNA within the cell). For more than 40years, a number of studies have consistently demonstrated the utility of DNA flow cytometry as a potential diagnostic and/or prognostic tool in patients with most epithelial tumors, including pre-invasive lesions (such as dysplasia) in the gastrointestinal tract. However, its availability as a clinical test has been limited to few medical centers due to the requirement for fresh tissue in earlier studies and perceived technical demands. However, more recent studies have successfully utilized formalin-fixed paraffin-embedded (FFPE) tissue to generate high-quality DNA content histograms, demonstrating the feasibility of this methodology. This review summarizes step-by-step methods on how to perform DNA flow cytometry using FFPE tissue and analyze DNA content histograms based on the published consensus guidelines in order to assist in the diagnosis and/or risk stratification of many different epithelial tumors, with particular emphasis on dysplasia associated with Barrett's esophagus and inflammatory bowel disease.

Abstract
Background: Salivary epigenetic biomarkers may detect esophageal cancer. Methods: A total of 256 saliva samples from esophageal adenocarcinoma patients and matched volunteers were analyzed with Illumina EPIC methylation arrays. Three datasets were created, using 64% for discovery, 16% for testing and 20% for validation. Modules of gene-based methylation probes were created using weighted gene coexpression network analysis. Module significance to disease and gene importance to module were determined and a random forest classifier generated using best-scoring gene-related epigenetic probes. A cost-sensitive wrapper algorithm maximized cancer diagnosis. Results: Using age, sex and seven probes, esophageal adenocarcinoma was detected with area under the curve of 0.72 in discovery, 0.73 in testing and 0.75 in validation datasets. Cancer sensitivity was 88% with specificity of 31%. Conclusion: We have demonstrated a potentially clinically viable classifier of esophageal cancer based on saliva methylation.

Abstract
Background: Gastroesophageal reflux disease is a common gastrointestinal disorder with one of its most feared complications being Barrett's esophagus (BE). Currently, most of the recommendations of BE management are driven by the level of dysplasia. However, the length of BE might also be related to the risk of dysplasia/malignant transformation. We aimed to determine the appropriate management of BE based on its length. Materials and Methods: A systematic literature review was conducted with searches made on PubMed, Embase, and Cochrane databases. Long-segment BE (LSBE) was defined as 3 cm or longer and short-segment BE (SSBE) as under 3 cm. Studies evaluating the behavior and management of SSBE and/or LSBE were included for analysis. Results: LSBE have greater risk of dysplasia or progression to esophageal adenocarcinoma compared to SSBE. Despite this greater risk, LSBE and SSBE are currently managed similarly based on the presence and degree of dysplasia. Endoscopic and ablative techniques may have higher level of success and less complications in SSBE, compared to LSBE. Decreasing time interval between surveillance may be a viable option for managing LSBE. Conclusions: Although many algorithms of monitoring and treatment of BE remain the same regardless of segment length, current evidence suggests that more aggressive management for LSBE might be needed due to its higher risk of malignant progression.

Abstract
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. In this review, we provide an overview on the management of Barrett's oesophagus, with a particular focus on recent advances in the diagnosis and recommendations for endoscopic therapy to reduce the risk of developing oesophageal adenocarcinoma.

Abstract
BACKGROUND Patients with early esophageal squamous cell neoplasias (ESCNs) that are totally or nearly totally circumferential face challenges in their clinical work. Endoscopic submucosal dissection (ESD) frequently leads to esophageal strictures. Endoscopic radiofrequency ablation (RFA), which stands out for its simplicity of use and low rate of stenosis, is a rapidly evolving therapeutic strategy for early ESCNs. We contrast ESD with RFA in order to find which method is best for the treatment of a wide range of esophageal diseases. METHODS Patients who had flat-type, early, large ESCNs (extending more than 3/4 of the esophageal circumference) treated endoscopically were enrolled retrospectively. The primary outcome measurements were adverse events and local control of the neoplastic lesion. RESULTS A total of 105 patients received treatment; 60 had ESD and 45 received RFA. Despite the patients receiving RFA typically having larger tumors (14.27 vs. 5.70 cm, P < 0.05), the local control of the neoplastic lesion and procedure-related complications were comparable between the ESD and RFA groups. A considerably higher risk of esophageal stenosis was observed in patients with extensive lesions in the ESD group compared to the RFA group (60% vs. 31%; P < 0.05), and the rate of refractory stricture is also higher than that of the RFA. CONCLUSION Both RFA and ESD are effective in treating large, flat, early ESCNs; however, ESD is more likely to cause side effects, such as esophageal stricture, particularly in lesions that are larger than 3/4 of the diameter. Before RFA, a more precise and thorough pretreatment examination should be performed. A more accurate pretreatment evaluation will be an important development direction for early esophageal cancer in future. After surgery, a strict routine review is crucial.

Abstract
BACKGROUND AND AIMS Real-world data on the adverse events and the survival benefit of Barrett's endoscopic therapy (BET) are limited. The aim of this study was to examine the safety and effectiveness (survival benefit) of BET in patients with neoplastic Barrett's esophagus (BE). METHODS An electronic health record-based database (TriNetX) was used to select patients with BE with dysplasia and esophageal adenocarcinoma (EAC) from 2016 to 2020. Primary outcome was 3-year mortality among patients with high-grade dysplasia (HGD) or EAC who underwent BET versus 2 comparison cohorts: patients with HGD or EAC who had not undergone BET and patients with GERD but no BE/EAC. Secondary outcome was adverse events (esophageal perforation, upper GI bleeding, chest pain, and esophageal stricture) after BET. To control for confounding variables, 1:1 propensity score matching was performed. RESULTS We identified 27,556 patients with BE and dysplasia, of whom 5295 underwent BET. After propensity score matching, patients with HGD and EAC who underwent BET had significantly lower 3-year mortality (HGD risk ratio [RR], .59; 95% CI, .49-.71; EAC RR, .53; 95% CI, .44-.65) compared with corresponding cohorts who did not undergo BET (P < .001). There was no difference in median 3-year mortality between control subjects (GERD without BE/EAC) compared with patients with HGD (RR, 1.04; 95% CI, .84-1.27) who underwent BET. Finally, there was no difference in median 3-year mortality between patients who underwent BET compared with patients who underwent esophagectomy among both HGD (RR, .67; 95% CI, .39-1.14; P =.14) and EAC (RR, .73; 95% CI, .47-1.13; P = .14). Esophageal stricture was the most common adverse event (6.5%) after BET. CONCLUSIONS Real-world, population-based evidence from this large database shows that endoscopic therapy is safe and effective for patients with BE. Endoscopic therapy is associated with a significantly lower 3-year mortality; however, it leads to esophageal strictures in 6.5% of treated patients.

Abstract
BACKGROUND: The addition of endoscopic ablative therapy plus proton pump inhibitors or fundoplication is postulated for the treatment of patients with long-segment Barrett´s esophagus (LSBE); however, it does not avoid acid and bile reflux in these patients. Fundoplication with distal gastrectomy and Roux-en-Y gastrojejunostomy is proposed as an acid suppression-duodenal diversion procedure demonstrating excellent results at long-term follow-up. There are no reports on therapeutic strategy with this combination. AIMS: To determine the early and long-term results observed in LSBE patients with or without low-grade dysplasia who underwent the acid suppression-duodenal diversion procedure combined with endoscopic therapy. METHODS: Prospective study including patients with endoscopic LSBE using the Prague classification for circumferential and maximal lengths and confirmed by histological study. Patients were submitted to argon plasma coagulation (21) or radiofrequency ablation (31). After receiving treatment, they were monitored at early and late follow-up (5–12 years) with endoscopic and histologic evaluation. RESULTS: Few complications (ulcers or strictures) were observed after the procedure. Re-treatment was required in both groups of patients. The reduction in length of metaplastic epithelium was significantly better after radiofrequency ablation compared to argon plasma coagulation (10.95 vs 21.15 mms for circumferential length; and 30.96 vs 44.41 mms for maximal length). Intestinal metaplasia disappeared in a high percentage of patients, and histological long-term results were quite similar in both groups. CONCLUSIONS: Endoscopic procedures combined with fundoplication plus acid suppression with duodenal diversion technique to eliminate metaplastic epithelium of distal esophagus could be considered a good alternative option for LSBE treatment.

Abstract
BACKGROUND AND AIMS Long-term durability data for effectiveness of radiofrequency ablation (RFA) to prevent esophageal adenocarcinoma in patients with dysplastic Barrett's esophagus (BE) are lacking. METHODS We prospectively collected data from 2535 patients with BE (mean length, 5.2 cm; range, 1-20) and neoplasia (20% low-grade dysplasia, 54% high-grade dysplasia, 26% intramucosal carcinoma) who underwent RFA therapy across 28 UK hospitals. We assessed rates of invasive cancer and performed detailed analyses of 1175 patients to assess clearance rates of dysplasia (CR-D) and intestinal metaplasia (CR-IM) within 2 years of starting RFA therapy. We assessed relapses and rates of return to CR-D (CR-D2) and CR-IM (CR-IM2) after further therapy. CR-D and CR-IM were confirmed by an absence of dysplasia and intestinal metaplasia on biopsy samples taken at 2 consecutive endoscopies. RESULTS Ten years after starting treatment, the Kaplan-Meier (KM) cancer rate was 4.1% with a crude incidence rate of .52 per 100 patient-years. CR-D and CR-IM after 2 years of therapy were 88% and 62.6%, respectively. KM relapse rates were 5.9% from CR-D and 18.7% from CR-IM at 8 years, with most occurring in the first 2 years. Both were successfully retreated with rates of CR-D2 of 63.4% and CR-IM2 of 70.0% 2 years after retreatment. EMR before RFA increased the likelihood of rescue EMR from 17.2% to 41.7% but did not affect the rate of CR-D, whereas rescue EMR after RFA commenced reduced CR-D from 91.4% to 79.7% (χ2P < .001). CONCLUSIONS RFA treatment is effective and durable to prevent esophageal adenocarcinoma. Most treatment relapses occur early and can be successfully retreated.

Abstract
Background Esophageal cancer causes considerable costs for health systems. Appropriate treatment options for patients with esophageal squamous cell carcinoma (ESCC) can reduce medical costs and provide more improved outcomes for health systems and patients. This study evaluates the cost-effectiveness of treatment interventions for patients with ESCC according to the Iranian health system. Material and methods A five-state Markov model with a 15-year time horizon was performed to evaluate the cost-effectiveness of treatment interventions based on stage for ESCC patients. Costs ($US 2021) and outcomes were calculated from the Iranian health system, with a discount rate of 3%. One-way sensitivity analyses were performed to assess the potential effects of uncertain variables on the model results. Results In stage I, the Endoscopic Mucosal Resection (EMR) treatment yielded the lowest total costs and highest total QALY for a total of $1473 per QALY, making it the dominant strategy compared with esophagectomy and EMR followed by ablation. In stages II and III, chemoradiotherapy (CRT) followed by surgery dominated esophagectomy. CRT followed by surgery was also cost-effective with an incremental cost-effectiveness ratio (ICER) of $2172.8 per QALY compared to CRT. Conclusion From the Iranian health system’s perspective, EMR was the dominant strategy versus esophagectomy and EMR followed by ablation for ESCC patients in stage I. The CRT followed by surgery was a cost-effective intervention compared to CRT and esophagectomy in stages II and III.

Abstract
BACKGROUND To assess the outcomes of patients with early esophageal cancer and high-grade dysplasia comparing esophagectomy, the historical treatment of choice, to endoscopic eradication therapy (EET). METHODS Retrospective cohort study of consecutive patients with early esophageal cancer/high-grade dysplasia, treated between 2000 and 2018 at a tertiary center. Primary outcomes were all-cause and disease-specific mortality assessed by multivariable Cox regression and a propensity score matching sub analysis, providing hazard ratios (HR) with 95% confidence intervals (CI) adjusted for age, tumor grade (G1/2 vs. G3), tumor stage, and lymphovascular invasion. Secondary outcomes included complications, hospital stay, and overall costs. RESULTS Among 269 patients, 133 underwent esophagectomy and 136 received EET. Adjusted survival analysis showed no difference between groups regarding all-cause mortality (HR 1.85, 95% CI 0.73, 4.72) and disease-specific mortality (HR 1.10, 95% CI 0.26, 4.65). In-hospital and 30-day mortality was 0% in both groups. The surgical group had a significantly higher rate of complications (Clavien-Dindo ≥3 26.3% vs. endoscopic therapy 0.74%), longer in-patient stay (median 14 vs. 0 days endoscopic therapy) and higher hospital costs(£16 360 vs. £8786 per patient). CONCLUSION This series of patients treated during a transition period from surgery to EET, demonstrates a primary endoscopic approach does not compromise oncological outcomes with the benefit of fewer complications, shorter hospital stays, and lower costs compared to surgery. It should be available as the gold standard treatment for patients with early esophageal cancer. Those with adverse prognostic features may still benefit from esophagectomy.

Abstract
Barrett's esophagus (BE) is a major risk factor for the development of esophageal adenocarcinoma (EAC). BE patients undergo periodic endoscopic surveillance with biopsies to detect dysplasia and EAC, but this strategy is imperfect owing to sampling error and inconsistencies in the diagnosis and grading of dysplasia, which may result in an inaccurate diagnosis or risk assessment for progression to EAC. The desire for more accurate diagnosis and better risk stratification has prompted the investigation and development of potential biomarkers that might assist pathologists and clinicians in the management of BE patients, allowing more aggressive endoscopic surveillance and treatment options to be targeted to high-risk individuals, while avoiding frequent surveillance or unnecessary interventions in those at lower risk. It is known that progression of BE to dysplasia and EAC is accompanied by a host of genetic alterations, and that exploration of these markers could be potentially useful to diagnose/grade dysplasia and/or to risk stratify BE patients. Several biomarkers have shown promise in identifying early neoplastic transformation and thus may be useful adjuncts to histologic evaluation. This review provides an overview of some of the currently available biomarkers and assays, including p53 immunostaining, Wide Area Transepithelial Sampling with Three-Dimensional Computer-Assisted Analysis (WATS3D), TissueCypher, mutational load analysis (BarreGen), fluorescence in situ hybridization, and DNA content abnormalities as detected by DNA flow cytometry.

Abstract
Background and study aims A novel technique for Barrett's esophagus (BE) ablation, termed hybrid APC, has recently been developed. The aims of this US pilot study were to evaluate the efficacy, tolerance and safety of hybrid APC for the treatment of BE. Patients and methods Patients with biopsy-proven BE referred to our tertiary care center over a 12-month period for mucosal ablation were eligible for this study. Efficacy of ablation was measured on follow-up endoscopy by demonstrating either a reduction of visible BE or biopsies proving complete resolution of intestinal metaplasia (CRIM). To evaluate tolerance and safety, patients were called on post-procedure days 1 and 7. Results Twenty-two patients with BE (4.5 % intramucosal carcinoma, 31.8 % high-grade dysplasia, 18.1 % low-grade dysplasia, 36.3 % non-dysplastic, 9.1 % indefinite for dysplasia) underwent 40 treatments with hybrid APC. All patients had endoscopic improvement of BE disease and 19 of 22 patients (86.4 %) achieved CRIM. With regard to tolerance, average pain scores (0 to 10 scale) on follow-up were 2.65 and 0.62 on days 1 and 7, respectively. With regards to safety, there were two treatment-related strictures (9.1 %) that required a single balloon dilation. Conclusions Hybrid APC appears to be promising in the treatment of BE. The ablation protocol used in this study demonstrated efficacy, tolerability, and a safety profile similar to radiofrequency ablation. Given the significant price difference between hybrid APC and other modalities for Barrett's ablation, this modality may be more cost-effective. These results warrant further study in a large prospective multicenter trial.

Abstract
BACKGROUND AND OBJECTIVES Endoscopic mucosal resection (EMR) and radiofrequency ablation (RFA) are effective treatments for dysplastic Barrett's esophagus (BE). This study evaluates efficacy, durability and safety in a single high-volume UK tertiary centre with 15-years' experience. METHODS Prospective data were collected from Nottingham University Hospitals 2004-2019 for endotherapy of dysplastic BE or intramucosal adenocarcinoma. Procedural outcome measures include complete resection, complications and surgery rates. Efficacy outcomes include complete remission of dysplasia (CR-D) and intestinal metaplasia (CR-IM), recurrence, treatment failure rates, durability of RFA, median follow up and tumor-associated mortality. RESULTS A total of 319 lesions were resected; 671 RFAs were performed on 239 patients. Median age was 67 (±9.5) years, male:female ratio was 5:1 and median BE length was C3 [interquartile range (IQR): 6] M6 (IQR: 5). The most common lesion was Paris IIa (64%) with a median size of 10 mm (3-70). Final histology was adenocarcinoma in 50%. Complete resection rates were 96%. The multiband mucosectomy technique (91%) was most commonly used. The median number of RFA sessions was 3 (IQR: 2). The rates of CR-D and CR-IM were 90.4%% and 89.8% achieved after a median of 20.1 (IQR: 14) months. The most common complications: EMR was bleeding 2.2% and RFA was stricture (5.4%) requiring a median of 2 (range 1-7) dilatations. Median follow up post CR-IM/CR-D was 38 months (14-60). Metachronous lesions developed in 4.7% after CR-D and tumor-related mortality was 0.8%. Dysplasia and intestinal metaplasia-free survival at 5 years was 95 and 90%, respectively. CONCLUSION BE endotherapy is minimally invasive, effective, safe and deliverable in a day-case setting.

Abstract
Barrett’s esophagus is the condition in which a metaplastic columnar epithelium
replaces the stratified squamous epithelium that normally lines the distal
esophagus. The condition develops as a consequence of chronic gastroesophageal
reflux disease and predisposes the patient to the development of esophageal
adenocarcinoma. The diagnosis and management of Barrett’s esophagus have
undergone dramatic changes over the years and continue to evolve today.
Endoscopic eradication therapy has revolutionized the management of dysplastic
Barrett’s esophagus and early esophageal adenocarcinoma by significantly
reducing the morbidity and mortality associated with the prior gold standard of
therapy, esophagectomy. The purpose of this review is to highlight current
principles in the management and endoscopic treatment of this disease.

Abstract
Barrett's esophagus (BE) is a precursor to esophageal adenocarcinoma and current practice is to establish endoscopic surveillance once diagnosed, in order to identify early dysplasia and neoplasia that has the potential to undergo endoscopic eradication therapy (EET). Before embarking upon EET the clinical team has a duty to consider all viable options and come to a plan based on recent evidence. The therapeutic approach varies greatly but largely adheres to the mantra of 'Detect-Resect-Ablate', in which high-quality endoscopy identifies BE associated pathology, associated lesions (if present) undergo safe endoscopic resection and remaining intestinal metaplasia in the esophagus is ablated to prevent recurrence of dysplasia. In this review, current practice, pitfalls, complications, and the future perspectives on practice in this field are discussed. The Western perspective is focused on here, with an outline of the differences in clinical practice with Asian nations and attempts to bridge these differences.

Abstract
BACKGROUND AND AIMS Radiofrequency ablation (RFA) is the preferred ablative modality for treating dysplastic Barrett's esophagus. The recently introduced self-sizing circumferential ablation catheter eliminates the need for a sizing balloon. Although it enhances efficiency, outcomes have not been compared with the previous manual-sizing catheter. We evaluated the comparative safety and efficacy of these 2 ablation systems in a large, multicenter cohort. METHODS Patients undergoing RFA at 3 tertiary care centers from 2005 to 2018 were included. Circumferential RFA was performed in a standard fashion, followed by focal RFA as needed. Outcomes were compared between the self-sizing and manual-sizing groups. The primary outcome was the rate of adverse events, including strictures, perforation, and bleeding. Secondary outcomes were procedure time and treatment efficacy, as assessed by rates and time to complete eradication of dysplasia (CE-D) and intestinal metaplasia (CE-IM). RESULTS Three hundred eighteen patients were included, 90 (28.3%) treated with the self-sizing catheter and 228 (71.7%) with the manual-sizing catheter. Twenty-one patients (6.6%) developed strictures (8 [8.9%] in the self-sizing group and 13 [5.7%] in the manual-sizing group, P = .32). Of the self-sizing strictures, 75% occurred at the 12J dose before widespread adoption of the current 10J treatment standard. One patient developed bleeding, and no perforations were encountered. Procedure time was significantly shorter in the self-sizing group. No significant differences were observed in rates of and time to CE-D and CE-IM. CONCLUSIONS These findings suggest that both systems are comparable in safety and efficacy. The use of the self-sizing system may enhance the efficiency of RFA for treating dysplastic Barrett's esophagus.

Radiofrequency ablation for Barrett's oesophagus related neoplasia with the 360 Express catheter: initial experience from the United Kingdom and Ireland-preliminary results. Surg Endosc 2021; 36:598-606. [PMID: 33547491 PMCID: PMC8741663 DOI: 10.1007/s00464-021-08325-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 01/13/2021] [Indexed: 01/10/2023]
Abstract
Background Radio-frequency ablation (RFA) for Barrett’s oesophagus (BE)-related neoplasia is currently used after endoscopic resection of visible neoplasia. The HALO 360 balloon has been used to ablate long segment BE. The Barrx™ 360 Express RFA self-sizing catheter (‘RFA Express’) may potentially allow quicker ablation times and improved treatment outcomes. The aim of this paper is to present real world data on the use of the 360 Express Device. Methods Centres in the UK and Ireland submitted cases where the RFA Express was used. The primary outcome was regression of BE at 3 months. Secondary outcomes were the rate of symptomatic stricture formation and resolution of intestinal metaplasia (CR-IM) and dysplasia (CR-D) at End of Treatment (EoT). Results 11 centres submitted 123 consecutive patients. 112 had a follow up endoscopy. The median age was 67 years (IQR 62–75). 3 dosimetries were used. The mean reduction in Circumferential (C) length was 78% ± 36 and mean reduction in Maximal length (M) was 55% ± 36. 17 patients (15%) developed strictures requiring dilation. There was a higher rate of stricture formation when the 12 J energy was used (p < 0.05). 47 patients had EoT biopsies, 40 (85%) had CR-D and 34(76%) had CR-IM. Conclusions The RFA 360 Express catheter shows reduction in length of baseline BE at 3 months after index treatment, and eradication of intestinal metaplasia and dysplasia at 12 months similar to other studies with earlier devices. It appears that the symptomatic stricture rate is slightly higher than previous series with the HALO 360 catheter. This study was performed as part of the HALO registry and has been approved by the Research Ethics Committee - MREC Number 08/H0714/27 Local project reference 08/0104 Project ID 15,033 IRAS Number 54678 EudraCT 2009-015980-1.

Persistent or recurrent Barrett's neoplasia after an endoscopic therapy session is associated with DNA content abnormality and can be detected by DNA flow cytometric analysis of paraffin-embedded tissue. Mod Pathol 2021; 34:1889-1900. [PMID: 34108638 PMCID: PMC8443444 DOI: 10.1038/s41379-021-00832-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 05/03/2021] [Accepted: 05/04/2021] [Indexed: 12/16/2022]
Abstract
Endoscopic therapy is currently the standard of care for the treatment of high-grade dysplasia (HGD) or intramucosal adenocarcinoma (IMC) in patients with Barrett's esophagus (BE). Visible lesions are treated with endoscopic mucosal resection (EMR), which is often coupled with radiofrequency ablation (RFA). However, endoscopic therapy may require multiple sessions (one session every 2-3 months) and does not always assure complete eradication of neoplasia. Furthermore, despite complete eradication, recurrences are not uncommon. This study assesses which potential risk factors can predict a poor response after endoscopic sessions. Forty-five BE patients who underwent at least one endoscopic session (EMR alone or ablation with or without preceding EMR) for the treatment of HGD/IMC, low-grade dysplasia (LGD), or indefinite for dysplasia (IND) were analyzed. DNA flow cytometry was performed on 82 formalin-fixed paraffin-embedded samples from the 45 patients, including 78 HGD/IMC, 2 LGD, and 2 IND. Eight non-dysplastic BE samples were used as controls. Three to four 60-micron thick sections were cut from each tissue block, and the area of HGD/IMC, LGD, or IND was manually dissected. Potential associations between clinicopathologic risk factors and persistent/recurrent HGD/IMC following each endoscopic session were examined using univariate and multivariate Cox models with frailty terms. Sixty (73%) of the 82 specimens showed abnormal DNA content (aneuploidy or elevated 4N fraction). These were all specimens with HGD/IMC (representing 77% of that group). Of these 60 HGD/IMC samples with abnormal DNA content, 42 (70%) were associated with subsequent development of persistent/recurrent HGD/IMC (n = 41) or esophageal adenocarcinoma (EAC; n = 1) within a mean follow-up time of 16 months (range: 1 month to 9.4 years). In contrast, only 6 (27%, all HGD/IMC) of the 22 remaining samples (all with normal DNA content) were associated with persistent/recurrent HGD/IMC. For outcome analysis per patient, 11 (24%) of the 45 patients developed persistent/recurrent HGD/IMC or EAC, despite multiple endoscopic sessions (mean: 3.6, range: 1-11). In a univariate Cox model, the presence of abnormal DNA content (hazard ratio [HR] = 3.8, p = 0.007), long BE segment ≥ 3 cm (HR = 3.4, p = 0.002), endoscopic nodularity (HR = 2.5, p = 0.042), and treatment with EMR alone (HR = 2.9, p = 0.006) were significantly associated with an increased risk for persistent/recurrent HGD/IMC or EAC. However, only abnormal DNA content (HR = 6.0, p = 0.003) and treatment with EMR alone (HR = 2.7, p = 0.047) remained as significant risk factors in a multivariate analysis. Age ≥ 60 years, gender, ethnicity, body mass index (BMI) ≥ 30 kg/m2, presence of hiatal hernia, and positive EMR lateral margin for neoplasia were not significant risk factors for persistent/recurrent HGD/IMC or EAC (p > 0.05). Three-month, 6-month, 1-year, 3-year, and 6-year adjusted probabilities of persistent/recurrent HGD/IMC or EAC in the setting of abnormal DNA content were 31%, 56%, 67%, 79%, and 83%, respectively. The corresponding probabilities in the setting of normal DNA content were 10%, 21%, 28%, 38%, and 43%, respectively. In conclusion, in BE patients with baseline HGD/IMC, both DNA content abnormality and treatment with EMR alone were significantly associated with persistent/recurrent HGD/IMC or EAC following each endoscopic session. DNA content abnormality as detected by DNA flow cytometry identifies HGD/IMC patients at highest risk for persistent/recurrent HGD/IMC or EAC, and it also serves as a diagnostic marker of HGD/IMC with an estimated sensitivity of 77%. The diagnosis of HGD/IMC in the setting of abnormal DNA content may warrant alternative treatment strategies as well as long-term follow-up with shorter surveillance intervals.

Abstract
Endoscopic eradication therapy (EET) is recommended for patients with Barrett's esophagus (BE)-associated neoplasia and is effective in achieving complete eradication of intestinal metaplasia (CE-IM). However, BE that is refractory to EET, defined as partial or no improvement in dysplasia after less than or equal to 3 ablative sessions, and the development of recurrence post-EET is not uncommon. Identification of refractory BE or recurrent intestinal metaplasia should prompt esophageal physiologic testing and modification of antireflux strategy, as appropriate. In patients who ultimately fail standard EET despite optimization of reflux control, salvage EET with alternate modalities may need to be considered.

Abstract
The treatment of early Barrett's esophagus (BE) has undergone a paradigm shift from surgical subtotal esophagectomy to organ-saving endoluminal treatment. Over the past 15 years, several high-quality studies were conducted to assess safe oncological outcome of endoscopic resection of mucosal adenocarcinoma and high-grade dysplasia. It became clear that add-on ablative therapy with radiofrequency ablation (RFA) significantly reduces recurrence risk of neoplasia after resection. In this review, we highlight the most essential elements to optimize outcomes of RFA of BE, addressing the correct indication and patient selection in combination with the most efficient and safest treatment protocols to obtain long-term durability.

Abstract
Endoscopic eradication therapy is a safe and effective therapy that has revolutionized the management of patients with Barrett's esophagus (BE)-related neoplasia. Despite this, there remains significant heterogeneity in clinical practice with consequent variation in patient outcomes. The aim of this article was to align consensus statements based on the best available evidence and expert opinion from the United States and United Kingdom to develop robust and measurable quality indicators that help to ensure patients with BE-related neoplasia receive the highest possible quality of care uniformly.

Abstract
INTRODUCTION Ablation of Barrett's esophagus (BE) is the preferred approach for the treatment of neoplasia without visible lesions. Limited data on cryoballoon ablation (CBA) suggest its potential clinical utility. We evaluated the safety and efficacy of CBA in a multicenter study of patients with neoplastic BE. METHODS In a prospective clinical trial, 11 academic and community centers recruited consecutive patients with BE of 1-6 cm length and low-grade dysplasia, high-grade dysplasia (HGD), or intramucosal adenocarcinoma (ImCA) confirmed by central pathology. Patients with symptomatic pre-existing strictures or visible BE lesions had dilation or endoscopic mucosal resection (EMR), respectively, before enrollment. A nitrous oxide cryoballoon focal ablation system was used to treat all visible columnar mucosa in up to 5 sessions. Study end points included complete eradication of all dysplasia (CE-D) and intestinal metaplasia (CE-IM) at 1 year. RESULTS One hundred twenty patients with BE with ImCA (20%), HGD (56%), or low-grade dysplasia (23%) were enrolled. In the intention-to-treat analysis, the CE-D and CE-IM rates were 76% and 72%, respectively. In the per-protocol analysis (94 patients), the CE-D and CE-IM rates were 97% and 91%, respectively. Postablation pain was mild and short lived. Fifteen subjects (12.5%) developed strictures requiring dilation. One patient (0.8%) with HGD progressed to ImCA, which was successfully treated with EMR. Another patient (0.8%) developed gastrointestinal bleeding associated with clopidogrel use. One patient (0.8%) had buried BE with HGD in 1 biopsy, not confirmed by subsequent EMR. DISCUSSION In patients with neoplastic BE, CBA was safe and effective. Head-to-head comparisons between CBA and other ablation modalities are warranted (clinicaltrials.gov registration NCT02514525).

Abstract
BACKGROUND AND AIMS Endoscopic resections and radiofrequency ablation (RFA) are the established treatments for Barrett's-associated dysplasia and early esophageal neoplasia. The UK RFA Registry collects patient outcomes from 24 centers treating patients in the United Kingdom and Ireland. Learning curves for treatment of Barrett's dysplasia and the impact of center caseload on patient outcomes is still unknown. METHODS We examined outcomes of 678 patients treated with RFA in the UK Registry using risk-adjusted cumulative sum control chart (RA-CUSUM) analysis to identify change points in complete resolution of intestinal metaplasia (CR-IM) and complete resolution of dysplasia (CR-D) outcomes. We compared outcomes between those treated at high-volume (>100 enrolled patients), medium-volume (51-100), and low-volume (<50) centers. RESULTS There was no association between center volume and CR-IM and CR-D rates, but recurrence rates were lower in high-volume versus low-volume centers (log rank P = .001). There was a significant change point for outcomes at 12 cases for CR-D (reduction from 24.5% to 10.4%; P < .001) and at 18 cases for CR-IM (30.7% to 18.6%; P < .001) from RA-CUSUM curve analysis. CONCLUSION Our data suggest that 18 supervised cases of endoscopic ablation may be required before competency in endoscopic treatment of Barrett's dysplasia can be achieved. The difference in outcomes between a high-volume and low-volume center does not support further centralization of services to only high-volume centers.

The utility of a methylation panel in the assessment of clinical response to radiofrequency ablation for Barrett's esophagus. EBioMedicine 2020; 58:102877.

Abstract
Background Radiofrequency ablation (RFA) is an effective treatment for dysplastic Barrett's esophagus (BE), but recurrence can occur after initial response. Currently there is uncertainty about how to best define histological remission. A DNA methylation panel on esophageal samples was previously shown to have high diagnostic accuracy for BE. We aimed to investigate this biomarker panel in the assessment of response to RFA treatment. Methods We retrospectively analyzed esophageal and gastroesophageal junction (GEJ) biopsies from patients with BE before and after RFA treatment. We quantified the extent of intestinal metaplasia (IM) based on number of glands with goblet cells (IM-Score) and expression of the intestinal factor trefoil factor-3 (TFF3-Score). Promoter methylation of 3 genes (ZNF345, TFP12, ZNF569) was measured by methylight (Meth-Score) throughout the RFA treatment pathway. Findings We included 45 patients (11 non-dysplastic BE, 14 low-grade dysplasia, 20 high-grade dysplasia/intramucosal cancer). Meth-Scores were significantly higher in BE with and without dysplasia and GEJ with IM compared to GEJ without IM (P<·001). Meth-scores significantly correlated with the extent of IM at the GEJ measured both with IM-Scores (rho=66·0%, P<·001), and TFF3-Scores (rho=75·6%, P<·001). In patients with residual IM at the GEJ, RFA re-treatment brought about a 7·6-fold reduction in the methylation levels. The Meth-score had an area under the ROC curve of 95·1% (95%CI 91·1% - 99·1%) differentiating BE from normal GEJ. Interpretation A DNA methylation panel can discriminate between the extent of histological IM in esophageal and junctional biopsies and could be used to objectively quantify residual disease following RFA.

Abstract
Objective: This economic evaluation aims to provide a preliminary assessment of the cost-effectiveness of radiofrequency ablation (RFA) compared with argon plasma coagulation (APC) when used to treat APC-refractory gastric antral vascular ectasia (GAVE) in symptomatic patients.Methods: A Markov model was constructed to undertake a cost-utility analysis for adults with persistent symptoms secondary to GAVE refractory to first line endoscopic therapy. The economic evaluation was conducted from a UK NHS and personal social services (PSS) perspective, with a 20-year time horizon, comparing RFA with APC. Patients transfer between health states defined by haemoglobin level. The clinical effectiveness data were sourced from expert opinion, resource use and costs were reflective of the UK NHS and benefits were quantified using Quality Adjusted Life Years (QALYs) with utility weights taken from the literature. The primary output was the Incremental Cost-Effectiveness Ratio (ICER), expressed as cost per QALY gained.Results: Over a lifetime time horizon, the base case ICER was £4840 per QALY gained with an 82.2% chance that RFA was cost-effective at a threshold of £20,000 per QALY gained. The model estimated that implementing RFA would result in reductions in the need for intravenous iron, endoscopic intervention and requirement for blood transfusions by 27.1%, 32.3% and 36.5% respectively. Compared to APC, RFA was associated with an estimated 36.7% fewer procedures.Conclusions: RFA treatment is likely to be cost-effective for patients with ongoing symptoms following failure of first line therapy with APC and could lead to substantive reductions in health care resource.

Abstract
Because of the rising incidence and lethality of esophageal adenocarcinoma, Barrett's esophagus (BE) is an increasingly important premalignant target for cancer prevention. BE-associated neoplasia can be safely and effectively treated with endoscopic eradication therapy (EET), incorporating tissue resection and ablation. Because EET has proliferated, managing patients after complete eradication of intestinal metaplasia has taken on increasing importance. Recurrence after complete eradication of intestinal metaplasia occurs in 8%-10% of the patients yearly, and the incidence may remain constant over time. Most recurrences occur at the gastroesophageal junction, whereas those in the tubular esophagus are endoscopically visible and distally located. A simplified biopsy protocol limited to the distal aspect of the BE segment, in addition to gastroesophageal junction sampling, may enhance efficiency and cost without significantly reducing recurrence detection. Similarly, research suggests that current surveillance intervals may be excessively frequent, failing to reflect the cancer risk reduction of EET. If validated, longer surveillance intervals could reduce the burden of resource-intensive endoscopic surveillance. Several important questions in post-EET management remain unanswered, including surveillance duration, the significance of gastric cardia intestinal metaplasia, and the role of advanced imaging and nonendoscopic sampling techniques in detecting recurrence. These merit further research to enhance quality of care and promote a more evidence-based approach.

Abstract
Background and study aims The standard radiofrequency ablation (RFA) protocol for Barrett's esophagus (BE) encompasses an intermediary cleaning phase between two ablation sessions. A simplified protocol omitting the cleaning phase is less labor-intensive but equally effective in studies based on single ablation procedures. The aim of this study was to compare efficacy and safety of the standard and simplified RFA protocols for the whole treatment pathway for BE, including both circumferential and focal devices. Patients and methods We performed a retrospective analysis of prospectively collected data on patients receiving RFA between January 2007 and August 2017 at two institutions. Outcomes assessed were: 1) complete remission of dysplasia (CR-D) and intestinal metaplasia (CR-IM) at 18 months; and 2) rate of esophageal strictures. Results One hundred forty-five patients were included of whom 73 patients received the standard and 72 patients received the simplified protocol. CR-D was achieved in 94.5 % and 95.8 % of patients receiving the standard and simplified protocol, respectively ( P = 0.71). CR-IM was achieved in 84.9 % and 77.8 % of patients treated with the standard and simplified protocol, respectively ( P = 0.27). Strictures were significantly more common among patients who received the simplified protocol (12.5 %) compared to the standard protocol (1.4 %; P = 0.008). The median number of esophageal dilations was one. Conclusion The simplified RFA protocol is as effective as the standard protocol in eradicating BE but carries a higher risk of strictures. This needs to be taken into account, particularly in patients with higher pretreatment risk of strictures, such as those with esophageal narrowing from previous endoscopic mucosal resection (EMR).

Abstract
BACKGROUND AND GOALS Visible lesions (VLs) in Barrett's esophagus (BE) are seen in 70% to 90% of patients presenting for endoscopic eradication therapy (EET). It is not known if there are any differences in outcomes of patients with flat dysplasia versus patients with VL. Our aim was to assess outcomes of EET in BE patients with VL and BE patients with flat dysplasia. STUDY This is a single center study with data drawn from a prospective registry of patients referred for EET of BE between 2011 and 2015. Demographic data, endoscopic findings, histologic findings, and response to EET were analyzed. RESULTS There were 264 patients of which 34 had flat dysplasia, 180 had VL before initiating EET (prevalent lesions) and 50 who developed VL during EET (incident lesions). Compared with patients with flat dysplasia, patients with VL had longer segments of BE (5 vs. 4 cm, P=0.002) and greater prevalence of high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) (63.6% vs. 29.4%, P<0.001). Incident lesions are less likely to harbor HGD/EAC compared with prevalent lesions (28.1% vs. 61.8%, P<0.001). There were no significant differences in eradication of metaplasia/dysplasia between the groups. No progression or recurrences were observed in flat dysplasia group. In VL group, 14 patients progressed (prevalent VL=11, incident VL=3) and 15 had recurrences (prevalent VL=11, incident VL=4). CONCLUSIONS About 19% of BE patients developed VL during EET. There is higher prevalence of HGD/EAC in prevalent VL compared with incident VL. However, the outcomes did not differ.

Prevalence and Incidence of Intestinal Metaplasia and Dysplasia of Gastric Cardia in Patients With Barrett's Esophagus After Endoscopic Therapy. Clin Gastroenterol Hepatol 2020; 18:82-88.e1.

Abstract
BACKGROUND & AIMS Endoscopic eradication therapy (EET) for Barrett's esophagus (BE) has unclear effects on the gastric cardia. We investigated the prevalence of intestinal metaplasia (IM) and dysplasia in the cardia after complete eradication of IM (CEIM) and the incidence of newly diagnosed cardia IM or dysplasia after EET. METHODS We performed a prospective study, from 2013 through 2016, of patients with previously successful EET undergoing surveillance after CEIM (cross-sectional group) and treatment-naïve patients with BE undergoing EET (longitudinal group). Standard biopsies were collected from multiple levels in the cardia and analyzed histologically. We calculated the prevalence (cross-sectional group) and the incidence (longitudinal group) of cardia IM or dysplasia after EET. RESULTS Of the 116 patients in the cross-sectional group, 17 (15%) had cardia IM or dysplasia after CEIM: 12 patients had IM, 2 patients were indefinite for dysplasia, and 3 patients had low-grade dysplasia. Cardia IM or dysplasia were most commonly found at the tops of gastric folds. Among 42 subjects in the longitudinal group, the pre-treatment prevalence of cardia IM or dysplasia was 28.5% (3 with non-dysplastic IM, 9 with dysplastic IM, 1 indefinite for dysplasia, 2 with low-grade dysplasia, 3 with high-grade dysplasia, and 3 with intramucosal cancer). All achieved CEIM. The incidence of cardia IM or dysplasia was 11.9% after 18 months of follow up. IM or dysplasia was more higher in the cardia after CEIM than in the tubular esophagus (P < .01). CONCLUSIONS In a prospective study, we found that cardia dysplasia becomes less, not more, common, after successful EET; recurrence of IM or dysplasia was more frequent in the cardia than the esophagus. Patients with BE undergoing EET should have careful examination of the cardia, with a single set of surveillance biopsies at the top of the gastric folds.

Abstract
Barrett's esophagus (BE) is a controversial condition. The significance of this condition lies in its premalignant potential, so it is important that clinically applicable biomarkers be identified for early detection and targeted prevention. Dysplasia is currently used as main biomarker, but others most recently surveyed in cancer also include microRNAs. Classically, BE was considered to be an acquired disease related to pathological gastroesophageal acid and bile reflux. However, some cases are associated with genetic predisposition, representing an inherited, familial form of BE. The actual gene, or genes, involved in this condition have not yet been identified. Main therapeutic options include medical treatment and antireflux surgery. Both types of treatment are equally efficient in controlling symptoms and neither is able to cause the metaplastic segment to disappear, which is why the risk of malignancy remains. However, we may use endoscopic radiofrequency to eradicate BE and replace it by the typical squamous epithelium of the esophagus. The currently accepted indications of radiofrequency in BE include low- and high-grade dysplasia, but not Barrett's esophagus without dysplasia. In conclusion, BE may have two different presentations: environmental ("human", reflux) or sporadic BE, which is the most common form, and genetic ("divine", inherited) or familiar BE, less common but with a greater risk for malignancy. As they might be two different diseases, surveillance programs and treatments should also be different.

Abstract
BACKGROUND AND AIMS Surveillance endoscopy is recommended after endoscopic eradication therapy (EET) for Barrett's esophagus (BE) because of the risk of recurrence. Currently recommended biopsy protocols are based on expert opinion and consist of sampling visible lesions followed by random 4-quadrant biopsy sampling throughout the length of the original BE segment. Despite this protocol, some recurrences are not visibly identified. We aimed to identify the anatomic location and histology of recurrences after successful EET with the goal of developing a more efficient and evidence-based surveillance biopsy protocol. METHODS We performed an analysis of a large multicenter database of 443 patients who underwent EET and achieved complete eradication of intestinal metaplasia (CE-IM) from 2005 to 2015. The endoscopic location of recurrence relative to the squamocolumnar junction (SCJ), visible recurrence identified during surveillance endoscopy, and time to recurrence after CE-IM were assessed. RESULTS Fifty patients with BE recurrence were studied in the final analysis. Seventeen patients (34%) had nonvisible recurrences. In this group, biopsy specimens demonstrating recurrence were taken from within 2 cm of the SCJ in 16 of these 17 patients (94%). Overall, 49 of 50 recurrences (98%) occurred either within 2 cm of the SCJ or at the site of a visible lesion. Late recurrences (>1 year) were more likely to be visible than early (<1 year) recurrences (P = .006). CONCLUSIONS Recurrence after EET detected by random biopsy sampling is identified predominately in the distal esophagus and occurs earlier than visible recurrences. As such, we suggest a modified biopsy protocol with targeted sampling of visible lesions followed by random biopsy sampling within 2 cm of the SCJ to optimize detection of recurrence after EET.

Abstract
INTRODUCTION Endoscopic therapy for the management of patients with Barrett's oesophagus (BE) neoplasia has significantly developed in the past decade; however, significant variation in clinical practice exists. The aim of this project was to develop expert physician-lead quality indicators (QIs) for Barrett's endoscopic therapy. METHODS The RAND/UCLA Appropriateness Method was used to combine the best available scientific evidence with the collective judgement of experts to develop quality indicators for Barrett's endotherapy in four subgroups: pre-endoscopy, intraprocedure (resection and ablation) and postendoscopy. International experts, including gastroenterologists, surgeons, BE pathologist, clinical nurse specialist and patient representative, participated in a three-round process to develop 15 QIs that fulfilled the RAND/UCLA definition of appropriateness. RESULTS 17 experts participated in round 1 and 20 in round 2. Of the 24 proposed QIs in round 1, 20 were ranked as appropriate (put through to round 2) and 4 as uncertain (discarded). At the end of round 2, a final list of 15 QIs were scored as appropriate. CONCLUSIONS This UK national consensus project has successfully developed QIs for patients undergoing Barrett's endotherapy. These QIs can be used by service providers to ensure that all patients with BE neoplasia receive uniform and high-quality care.

Abstract
Quality indicators have been proposed for endoscopic eradication therapy of Barrett's esophagus (BE). One such measure suggests that complete eradication of intestinal metaplasia (CE-IM) should be achieved within 18 months of starting treatment. The aim of this study was to assess whether achievement of CE-IM within 18 months is associated with improved long-term clinical outcomes. This was a retrospective cohort study of BE patients who underwent endoscopic eradication. Time to CE-IM was recorded and categorized as ≤ or > 18 months. The main outcome measures were recurrence of IM and of dysplasia after CE-IM, defined as a single endoscopy without endoscopic evidence of BE or histologic evidence of intestinal metaplasia. Recurrence was analyzed using the Kaplan-Meier method and multivariable Cox proportional hazards modeling. A total of 290 patients were included in the analyses. The baseline histology was high-grade dysplasia or intramucosal carcinoma in 74.2% of patients. CE-IM was achieved in 85.5% of patients, and 54.1% of the cohort achieved CE-IM within 18 months. Achieving CE-IM within 18 months was not associated with reduced risk of recurrence of IM or dysplasia in both unadjusted and adjusted analyses. In this cohort, older age and increased BE length were associated with IM recurrence, and increased hiatal hernia size was associated with dysplasia recurrence. Compared to longer times, achieving CE-IM within 18 months was not associated with a reduced risk of recurrence of IM or dysplasia. Alternative evidence-based quality metrics for endoscopic eradication therapy should be identified.

Abstract
BACKGROUND AND AIMS Endoscopic eradication therapy (EET) is the first line approach for treating Barrett's oesophagus (BE) related neoplasia globally. The British Society of Gastroenterology (BSG) recommend EET with combined endoscopic resection (ER) for visible dysplasia followed by endoscopic ablation in patients with both low and high grade dysplasia (LGD and HGD). The aim of this study is to perform a cost-effectiveness analysis for EET for treatment of all grades of dysplasia in BE patients. METHODS A Markov cohort model with a lifetime time horizon was used to undertake a cost-effectiveness analysis. A hypothetical cohort of UK patients diagnosed with BE entered the model. Patients in the treatment arm with LGD and HGD received EET and patients with non-dysplastic BE (NDBE) received endoscopic surveillance only. In the comparator arm, patients with LGD, HGD and NDBE received endoscopic surveillance only. A UK National Health Service (NHS) perspective was adopted and the incremental cost-effectiveness ratio (ICER) was calculated. Sensitivity analysis was conducted on key input parameters. RESULTS EET for patients with LGD and HGD arising in BE is cost-effective compared to endoscopic surveillance alone (lifetime ICER £3006 per quality adjusted life year [QALY] gained). The results show that, as the time horizon increases, the treatment becomes more cost-effective. The 5 year financial impact to the UK NHS of introducing EET is £7.1m. CONCLUSIONS EET for patients with low and high grade BE dysplasia, following updated guidelines from the BSG, has been shown to be cost-effective for patients with BE in the UK.

Abstract
BACKGROUND AND AIMS Endoscopic resection (ER) is safe and effective for Barrett's esophagus (BE) containing high-grade dysplasia (HGD) or mucosal adenocarcinoma (T1A). The risk of metachronous neoplasia is reduced by ablation of residual BE by using radiofrequency ablation (RFA) or argon plasma coagulation (APC). These have not been compared directly. We aimed to recruit up to 100 patients with BE and HGD or T1A confirmed by ER over 1 year in 6 centers in a randomized pilot study. METHODS Randomization was 1:1 to RFA or APC (4 treatments allowed at 2-month intervals). Recruitment, retention, dysplasia clearance, clearance of benign BE, adverse events, healthcare costs, and quality of life by using EQ-5D, EORTC QLQ-C30, or OES18 were assessed up to the end of the trial at 12 months. RESULTS Of 171 patients screened, 76 were randomized to RFA (n = 36) or APC (n = 40). The mean age was 69.7 years, and 82% were male. BE was <5 cm (n = 27), 5 to 10 cm (n = 45), and >10 cm (n = 4). Sixty-five patients completed the trial. At 12 months, dysplasia clearance was RFA 79.4% and APC 83.8% (odds ratio [OR] 0.7; 95% confidence interval [CI], 0.2-2.6); BE clearance was RFA 55.8%, and APC 48.3% (OR 1.4; 95% CI, 0.5-3.6). A total of 6.1% (RFA) and 13.3% (APC) had buried BE glands. Adverse events (including stricture rate after starting RFA 3/36 [8.3%] and APC 3/37 [8.1%]) and quality of life scores were similar, but RFA cost $27491 more per case than APC. CONCLUSION This pilot study suggests similar efficacy and safety but a cost difference favoring APC. A fully powered non-inferiority trial is appropriate to confirm these findings.

Treatment of high-grade dysplasia and intramucosal carcinoma using radiofrequency ablation or endoscopic mucosal resection + radiofrequency ablation: Meta-analysis and systematic review. World J Gastrointest Endosc 2019; 11:239-248. [PMID: 30918589 PMCID: PMC6425278 DOI: 10.4253/wjge.v11.i3.239] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2018] [Revised: 02/13/2019] [Accepted: 02/20/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The progression of Barrett’s esophagus (BE) to early esophageal carcinoma occurs sequentially; the metaplastic epithelium develops from a low-grade dysplasia to a high-grade dysplasia (HGD), resulting in early esophageal carcinoma and, eventually, invasive carcinoma. Endoscopic approaches including resection and ablation can be used in the treatment of this condition.
AIM To compare the effectiveness of radiofrequency ablation (RFA) vs endoscopic mucosal resection (EMR) + RFA in the endoscopic treatment of HGD and intramucosal carcinoma.
METHODS In accordance with PRISMA guidelines, this systematic review included studies comparing the two endoscopic techniques (EMR + RFA and RFA alone) in the treatment of HGD and intramucosal carcinoma in patients with BE. Our analysis included studies involving adult patients of any age with BE with HGD or intramucosal carcinoma. The studies compared RFA and EMR + RFA methods were included regardless of randomization status.
RESULTS The seven studies included in this review represent a total of 1950 patients, with 742 in the EMR + RFA group and 1208 in the RFA alone group. The use of EMR + RFA was significantly more effective in the treatment of HGD [RD 0.35 (0.15, 0.56)] than was the use of RFA alone. The evaluated complications (stenosis, bleeding, and thoracic pain) were not significantly different between the two groups.
CONCLUSION Endoscopic resection in combination with RFA is a safe and effective method in the treatment of HGD and intramucosal carcinoma, with higher rates of remission and no significant differences in complication rates when compared to the use of RFA alone.

Abstract
Background Gastric antral vascular ectasia (GAVE) is a rare cause of gastrointestinal bleeding, often causing iron deficiency anaemia. Previous studies have looked at the management of this with argon plasma coagulation, laser therapy and endoscopic band ligation. Methods This was a single-centre prospective study to evaluate the efficacy and safety of radiofrequency ablation (RFA) in patients with GAVE with persistent anaemia refractory to at least one session of first-line endoscopic therapy. Patients were treated with a through-the-scope (TTS) radiofrequency catheter at two endoscopic sessions six weeks apart. The primary outcome was change in haemoglobin at six months posttreatment. The secondary outcomes were reduction in blood or iron requirements, endoscopic surface area regression and complications. Results Twenty patients were treated. The mean change in haemoglobin at six months was +12.6 g/l (95% confidence interval 11.7-24.3 g/l), paired t test p < 0.001. At six months, three of 14 individuals who had required blood transfusions had ongoing blood transfusions and five of 17 who had required iron had ongoing iron needs. Surface area regression was scored as 74% ± 25% but no correlation was seen between this and other outcomes. Three of 20 patients experienced pain which was managed with oral analgesia. Of the 14 patients who had reached 12-month follow-up, three required retreatment (21%). Discussion This small study suggests that RFA is a safe and effective treatment for GAVE. Our study uses the TTS catheter compared to other studies, and demonstrates prolonged improvement in haemoglobin and reduction in blood and iron requirements with a novel assessment of surface area regression.

Abstract
Early detection, including cancer screening and surveillance, is emerging as one of the most important topics in modern oncology. Because symptomatic presentation remains the predominant route to cancer diagnosis, there is a growing interest in developing techniques to detect the disease at an early, curative stage. Moreover, growing understanding of cancer biology has paved the way for prevention studies with the focus on therapeutic interventions for premalignant conditions. Where there is a recognisable precursor stage, such as a colorectal adenoma or Barrett's metaplasia, the removal of abnormal tissue prevents the development of cancer and enables stratification of the patient to a high-risk group requiring further surveillance. Here, we provide a review of the available technologies for early diagnosis and minimally-invasive treatment.

Abstract
GOALS AND BACKGROUND Two common endoscopic therapies for eradication of dysplastic Barrett's esophagus are radiofrequency ablation (RFA) and liquid nitrogen spray cryotherapy (LNC). There is no data comparing postprocedural pain. This study aimed to compare the incidence of postprocedural pain between the 2 ablation modalities. METHODS This is a multicenter prospective study in which pain intensity scores and the presence of dysphagia were assessed immediately before and after treatment, 48 hours posttreatment and at 3 weeks posttreatment using validated instruments. RESULTS Of 94 patients, 35 underwent LNC and 59 underwent RFA [36 with focal radiofrequency ablation (RFA-F) and 23 with circumferential radiofrequency ablation (RFA-C)]. Immediately posttreatment, patients in the LNC group reported an average Numeric Pain Scale score that was lower than in the RFA groups [LNC 0.41 vs. RFA-F 1.18 (P=0.026), LNC 0.41 vs. RFA-C 1.38 (P=0.010)]. These differences persisted at 48 hours posttreatment [LNC 0.76 vs. RFA-F 1.77 (P=0.013), LNC 0.76 vs. RFA-C 1.73 (P=0.018)]. The odds of pain after RFA were at least 5 times greater than after LNC [immediately posttreatment odds ratio, 5.26 (95% confidence interval, 1.85-14.29) and 48 h posttreatment odds ratio, 5.56 (95% confidence interval, 2.27-14.29)]. There was no difference in dysphagia after treatment in either group, at any time point (P=0.429). CONCLUSION LNC was associated with less postprocedural pain when compared with RFA. These results help inform patients and physicians about the expected symptoms after ablative endotherapy.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known measurable factor associated with esophageal adenocarcinoma. The development of endoscopic eradication therapy (EET) has transformed the way BE is managed. Given the fairly recent development of EET, its role in BE is still evolving. RECENT FINDINGS This paper discusses the challenges that endoscopists face at the preprocedural, intraprocedural, and postprocedural stages of BE management. These include challenges in risk stratification, dysplasia detection, ablation methods and dosimetry, choice of resection technique, and management of refractory disease. Despite the advances in EET in BE, there remain challenges that this review focuses on. Future research into these challenges will optimize ablation techniques and strategies in the future.

Abstract
Refractory benign oesophageal strictures are an infrequent presentation but a cause of significant morbidity and mortality. The treatment of these strictures has changed little in recent years, yet new evidence is emerging for the optimal timing and application of different therapies. In this article, we have carefully reviewed the current literature on the evaluation and management of refractory strictures and provided practical advice as to their management. A number of areas require attention in future research, including carefully designed randomised trials of endoscopic and medical therapies, and a focus on risk factors at a patient and molecular level to facilitate development of medical therapies that can reduce recurrent fibrosis in these patients.

Outcomes of Endoscopic Submucosal Dissection vs Esophagectomy for T1 Esophageal Squamous Cell Carcinoma in a Real-World Cohort. Clin Gastroenterol Hepatol 2019; 17:73-81.e3.

Abstract
BACKGROUND & AIMS Esophagectomy is the standard treatment for early-stage esophageal squamous cell carcinoma (EESCC), but patients who undergo this procedure have high morbidity and mortality. Endoscopic submucosal dissection (ESD) is a less-invasive procedure for treatment of EESCC, but is considered risky because this tumor frequently metastasizes to the lymph nodes. We aimed to directly compare outcomes of patients with EESCC treated with ESD vs esophagectomy. METHODS We performed a retrospective cohort study of patients with T1a-m2/m3, or T1b EESCCs who underwent ESD (n = 322) or esophagectomy (n = 274) from October 1, 2011 through September 31, 2016 at Zhongshan Hospital in Shanghai, China. The primary outcome was all-cause mortality at the end of follow up (minimum of 6 months). Secondary outcomes included operation time, hospital stay, cost, perioperative mortalities/severe non-fatal adverse events, requirement for adjuvant therapies, and disease-specific mortality and cancer recurrence or metastasis at the end of the follow up period. RESULTS Patients who underwent ESD were older (mean 63.5 years vs 62.3 years for patients receiving esophagectomy; P = .006) and a greater proportion was male (80.1% vs 70.4%; P = .006) and had a T1a tumor (74.5% vs 27%; P = .001). A lower proportion of patients who underwent ESD had perioperative mortality (0.3% vs 1.5% of patients receiving esophagectomy; P = .186) and non-fatal severe adverse events (15.2% vs 27.7%; P = .001)-specifically lower proportions of esophageal fistula (0.3% of patients receiving ESD vs 16.4% for patients receiving esophagectomy; P = .001) and pulmonary complications (0.3% vs 3.6%; P = .004). After a median follow-up time of 21 months (range, 6-73 months), there were no significant differences between treatments in all-cause mortality (7.4% for ESD vs 10.9%; P = .209) or rate of cancer recurrence or metastasis (9.1% for ESD vs 8.9%; P = .948). Disease-specific mortality was lower among patients who received ESD (3.4%) vs patients who patients who received esophagectomy (7.4%) (P = .049). In Cox regression analysis, depth of tumor invasion was the only factor associated with all-cause mortality (T1a-m3 or deeper vs T1a-m2: hazard ration, 3.54; P = .04). CONCLUSION In a retrospective study of patients with T1am2/m3 or T1b EESCCs treated with ESD (n = 322) or esophagectomy (n = 274), we found lower proportions of patients receiving ESD to have perioperative adverse events or disease specific mortality after a median follow up time of 21 months. We found no difference in overall survival or cancer recurrence or metastasis in patients with T1a or T1b ESCCs treated with ESD vs esophagectomy.

Abstract
Patients with esophageal intestinal metaplasia, or Barrett's esophagus, may undergo dysplastic changes that eventually lead to invasive adenocarcinoma. Endoscopic therapy in the form of radiofrequency ablation and cryoablation has been described as a minimally invasive intervention to halt this sequence of dysplasia to carcinoma. Studies demonstrate that the use of radiofrequency ablation and cryoablation is highly successful at eradicating intestinal metaplasia and dysplasia and reducing the risk of disease progression. Furthermore, these modalities also may be used in combination with endoscopic mucosal resection, or as stand-alone therapy, for the treatment of intramucosal carcinoma, potentially circumventing the need for surgery.

Abstract
In the past decade there have been technological advances in Endoscopic Eradication Therapy (EET) for the management of patients with oesophageal neoplasia and early cancer. Multiple endoscopic techniques now exist for both squamous and Barrett's oesophagus associated neoplasia or early cancer. A fundamental aspect of endotherapy is removal of the target lesion by endoscopic mucosal resection, or endosopic submucosal dissection. Residual tissue is subsequently ablated to remove the risk of recurrence. The most validated technique for Barrett's oesophagus is radiofrequency ablation, but other techniques such as hybrid-APC and cryotherapy also show good results. This chapter will discuss the evolution of EET, and which patients are most likely to benefit. It will also explore the evidence behind the success of different techniques and provide practical advice on how to carry out the endoscopic techniques with a focus on radiofrequency ablation and endoscopic mucosal resection in particular.
