Abstract
BACKGROUND Surveillance of nondysplastic Barrett's esophagus (NDBE) is recommended to identify progression to dysplasia; however, the most cost-effective strategy remains unclear. Mutation of TP53 or aberrant expression of p53 have been associated with the development of dysplasia in BE. We sought to determine if surveillance intervals for BE could be stratified based on p53 expression. METHODS A Markov model was developed for NDBE. Patients with NDBE underwent p53 immunohistochemistry (IHC) and those with abnormal p53 expression underwent surveillance endoscopy at 1 year, while patients with normal p53 expression underwent surveillance in 3 years. Patients with dysplasia underwent endoscopic therapy and surveillance. RESULTS On base-case analysis, the strategy of stratifying surveillance based on abnormal p53 IHC was cost-effective relative to conventional surveillance and a natural history model, with an incremental cost-effectiveness ratio (ICER) of $8258 for p53 IHC-based surveillance. Both the conventional and p53-stratified surveillance strategies dominated the natural history model. On probabilistic sensitivity analysis, the p53 IHC strategy ($28 652; 16.78 quality-adjusted life years [QALYs]) was more cost-effective than conventional surveillance ($25 679; 16.17 QALYs) with a net monetary benefit of $306 873 compared with conventional surveillance ($297 642), with an ICER <$50 000 in 96% of iterations. The p53-stratification strategy was associated with a 14% reduction in the overall endoscopy burden and a 59% increase in dysplasia detection. CONCLUSION A surveillance strategy for BE based on abnormal p53 IHC is cost-effective relative to a conventional surveillance strategy and is likely to be associated with higher rates of dysplasia diagnosis.

Abstract
BACKGROUND & AIMS Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Endoscopic eradication therapy (EET) can be effective in eradicating BE and related neoplasia and has greater risk of harms and resource use than surveillance endoscopy. This clinical practice guideline aims to inform clinicians and patients by providing evidence-based practice recommendations for the use of EET in BE and related neoplasia. METHODS The Grading of Recommendations Assessment, Development and Evaluation framework was used to assess evidence and make recommendations. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients, conducted an evidence review, and used the Evidence-to-Decision Framework to develop recommendations regarding the use of EET in patients with BE under the following scenarios: presence of (1) high-grade dysplasia, (2) low-grade dysplasia, (3) no dysplasia, and (4) choice of stepwise endoscopic mucosal resection (EMR) or focal EMR plus ablation, and (5) endoscopic submucosal dissection vs EMR. Clinical recommendations were based on the balance between desirable and undesirable effects, patient values, costs, and health equity considerations. RESULTS The panel agreed on 5 recommendations for the use of EET in BE and related neoplasia. Based on the available evidence, the panel made a strong recommendation in favor of EET in patients with BE high-grade dysplasia and conditional recommendation against EET in BE without dysplasia. The panel made a conditional recommendation in favor of EET in BE low-grade dysplasia; patients with BE low-grade dysplasia who place a higher value on the potential harms and lower value on the benefits (which are uncertain) regarding reduction of esophageal cancer mortality could reasonably select surveillance endoscopy. In patients with visible lesions, a conditional recommendation was made in favor of focal EMR plus ablation over stepwise EMR. In patients with visible neoplastic lesions undergoing resection, the use of either endoscopic mucosal resection or endoscopic submucosal dissection was suggested based on lesion characteristics. CONCLUSIONS This document provides a comprehensive outline of the indications for EET in the management of BE and related neoplasia. Guidance is also provided regarding the considerations surrounding implementation of EET. Providers should engage in shared decision making based on patient preferences. Limitations and gaps in the evidence are highlighted to guide future research opportunities.

Abstract
INTRODUCTION Endoscopic eradication therapy (EET) is the preferred treatment for Barrett's esophagus (BE)-related neoplasia patients. However, the impact of EET on critical outcomes, outside of clinical trials and registry data, remains scarcely studied. We aimed to assess real-world practice patterns and clinical outcomes among BE patients undergoing EET. METHODS TriNetX is a large research network comprising linked inpatient and outpatient electronic-health record-derived data from over 80,000,000 patients. Patients with a diagnosis of BE from 2015 to 2020 were identified and included if they underwent EET during the study period. The primary outcome was the progression to EAC after index EET. Secondary outcomes included rate of esophagectomy, and all-cause mortality. All outcomes were stratified by baseline histology. The incidence of EAC and all-cause mortality were reported in person-years and adjusted for age and sex. RESULTS A total of 4114 patients were analyzed. Distribution of baseline histology was as follows: NDBE (11.8%), LGD (21.4%), HGD (26.4%), EAC (20.8%), and unspecified (19.6%). The total incidence of EAC after index EET was 6.01 per 1000 person-years (PY) for the entire cohort with the highest rate in HGD patients (12.9/1000 PY). The incidence of all-cause mortality was 13.23 per 1000 PY with the highest rates in EAC patients (25.1 per 1000 PY). Rates of esophagectomy were < 1% for all grades of dysplasia. CONCLUSION The results of this study provide "real-world" data on critical outcomes for BE patients undergoing EET, demonstrating a low risk of incident EAC, all-cause mortality, and need for esophagectomy.

Cost-effectiveness Analysis of Radiofrequency Ablation in Patients With Barrett Esophagus and High-Grade Dysplasia or Low-Grade Dysplasia. Clin Ther 2023:S0149-2918(23)00136-4. [PMID: 37137786 DOI: 10.1016/j.clinthera.2023.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 04/07/2023] [Accepted: 04/14/2023] [Indexed: 05/05/2023]
Abstract
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. Clinical and quality-of-life parameters were derived from a review of the literature and expert opinions, whereas Italian national tariffs were used as a proxy for costs. FINDINGS RFA dominated esophagectomy in patients with HGD with a probability of 83%. For patients with LGD, RFA was more effective and more costly than active surveillance (incremental cost-effectiveness ratio, €6276 per quality-adjusted life-year). At a cost-effectiveness threshold of €15,272, the probability of RFA being the optimal strategy in this population was close to 100%. Model results were sensitive to the cost of the interventions and utility weights used in the different disease states. IMPLICATIONS RFA is likely to be the optimal choice for patients with LGD and HGD in Italy. Italy is discussing the implementation of a national program for the health technology assessment of medical devices, requiring more studies to prove value for money of emerging technologies.

Abstract
Background and study aims Radiofrequency ablation (RFA) for dysplastic Barrett's esophagus (BE) has resulted in a paradigm shift in the management of BE. Despite widespread adoption of RFA, the optimal surveillance interval of the ablated zone is unclear. Methods A patient-level discrete time cycle Markov model was developed to model clinical surveillance strategies post-RFA for BE. Three surveillance strategies were examined: the American College of Gastroenterology (ACG) strategy based on ACG guidelines for post-RFA surveillance, the Cotton strategy based on data from the USA and UK RFA registries, and the UK strategy in line with surveillance strategies in UK centers. Monte-Carlo deterministic and probabilistic analyses were performed over 10,000 iterations (i. e., representing 10,000 patient journeys) and sensitivity analyses were carried out on the variables used in the model. Results On base-case analysis, the ACG strategy was the most cost-effective strategy, at a mean cost of £ 11,733 ($ 16,396) (standard deviation (SD) 1520.15) and a mean effectiveness of 12.86 (SD 0.07) QALYs. Probabilistic sensitivity analysis demonstrated that the ACG model was the most cost-effective strategy with a net monetary benefit (NMB) of £ 5,136 ($ 7177) (SD 241) compared to the UK strategy and a NMB of £ 7017 ($ 9,806) (SD 379) compared to the Cotton strategy. At a willingness to pay (WTP) threshold of £ 20,000 ($ 27,949), the ACG model was superior to the other strategies as the most cost-effective strategy. Conclusions A post-RFA surveillance strategy based on the ACG guidelines seems to be the most cost-effective surveillance option.

Abstract
Simple Summary Oesophageal adenocarcinoma (OAC) is a type of cancer of the oesophagus (food pipe) which is associated with poor patient outcomes. Barrett’s oesophagus (BO) is a precancerous condition of the oesophagus associated with chronic heartburn. Currently, surveillance programs exist which monitor patients with BO to prevent it from developing into OAC. However, these surveillance programs are expensive and unpleasant for patients. Prognostic biomarkers are signs which could be measured to determine the chance of someone with BO developing OAC, allowing more targeted surveillance. Similarly, diagnostic biomarkers are indicators which could be measured to see if someone has OAC. Developing new diagnostic biomarkers could allow wider population testing. Only a small proportion of patients with OAC respond to treatment before surgery. Predictive biomarkers could be measured to predict whether someone would respond to the treatments, allowing more individualized therapy. This review focuses on potential biomarkers which could improve patient outcomes in BO/OAC. Abstract Oesophageal adenocarcinoma (OAC) incidence has increased dramatically in the developed world, yet outcomes remain poor. Extensive endoscopic surveillance programs among patients with Barrett’s oesophagus (BO), the precursor lesion to OAC, have aimed to both prevent the development of OAC via radiofrequency ablation (RFA) and allow earlier detection of disease. However, given the low annual progression rate and the costs of endoscopy/RFA, improvement is needed. Prognostic biomarkers to stratify BO patients based on their likelihood to progress would enable a more targeted approach to surveillance and RFA of high-risk precursor lesions, improving the cost–risk–benefit ratio. Similarly, diagnostic biomarkers for OAC could enable earlier diagnosis of disease by allowing broader population screening. Current standard treatment for locally advanced OAC includes neoadjuvant chemotherapy (+/− radiotherapy) despite only a minority of patients benefiting from neoadjuvant treatment. Accordingly, biomarkers predictive of response to neoadjuvant therapy could improve patient outcomes by reducing time to surgery and unnecessary toxicity for the patients who would have received no benefit from the therapy. In this mini-review, we will discuss the emerging biomarkers which promise to dramatically improve patient outcomes along the BO-OAC disease sequence.

Abstract
BACKGROUND & AIMS Guidelines suggest endoscopic screening for esophageal adenocarcinoma (EAC) among individuals with symptoms of gastroesophageal reflux disease (GERD) and additional risk factors. We aimed to determine at what age to perform screening and whether sex and race should influence the decision. METHODS We conducted comparative cost-effectiveness analyses using 3 independent simulation models. For each combination of sex and race (White/Black, 100,000 individuals each), we considered 41 screening strategies, including one-time or repeated screening. The optimal strategy was that with the highest effectiveness and an incremental cost-effectiveness ratio <$100,000 per quality-adjusted life-year gained. RESULTS Among White men, 536 EAC deaths were projected without screening, and screening individuals with GERD twice at ages 45 and 60 years was optimal. Screening the entire White male population once at age 55 years was optimal in 26% of probabilistic sensitivity analysis runs. Black men had fewer EAC deaths without screening (n = 84), and screening those with GERD once at age 55 years was optimal. Although White women had slightly more EAC deaths (n = 103) than Black men, the optimal strategy was no screening, although screening those with GERD once at age 55 years was optimal in 29% of probabilistic sensitivity analysis runs. Black women had a very low burden of EAC deaths (n = 29), and no screening was optimal, as benefits were very small and some strategies caused net harm. CONCLUSIONS The optimal strategy for screening differs by race and sex. White men with GERD symptoms can potentially be screened more intensely than is recommended currently. Screening women is not cost-effective and may cause net harm for Black women.

Abstract
Barrett’s esophagus (BE), a precursor for esophageal adenocarcinoma (EAC), is
defined as salmon-colored mucosa extending more than 1 cm proximal to the
gastroesophageal junction with histological evidence of intestinal metaplasia.
The actual risk of EAC in nondysplastic Barrett’s esophagus (NDBE) is low with
an annual incidence of 0.3%. The mainstay in the management of NDBE is control
of gastroesophageal reflux disease (GERD) along with enrollment in surveillance
programs. The current recommendation for surveillance is four-quadrant biopsies
every 2 cm (or 1 cm in known or suspected dysplasia) followed by biopsy of
mucosal irregularity (nodules, ulcers, or other visible lesions) performed at 3-
to 5-year intervals. Challenges to surveillance include missed cancers,
suboptimal adherence to surveillance guidelines, and lack of strong evidence for
efficacy. There is minimal role for endoscopic eradication therapy in NDBE. The
role for enhanced imaging techniques, artificial intelligence, and risk
prediction models using clinical data and molecular markers is evolving.

Abstract
Barrett's esophagus (BE) is a common condition associated with chronic gastroesophageal reflux disease. BE is the only known precursor to esophageal adenocarcinoma, a highly lethal cancer with an increasing incidence over the last 5 decades. These revised guidelines implement Grading of Recommendations, Assessment, Development, and Evaluation methodology to propose recommendations for the definition and diagnosis of BE, screening for BE and esophageal adenocarcinoma, surveillance of patients with known BE, and the medical and endoscopic treatment of BE and its associated early neoplasia. Important changes since the previous iteration of this guideline include a broadening of acceptable screening modalities for BE to include nonendoscopic methods, liberalized intervals for surveillance of short-segment BE, and volume criteria for endoscopic therapy centers for BE. We recommend endoscopic eradication therapy for patients with BE and high-grade dysplasia and those with BE and low-grade dysplasia. We propose structured surveillance intervals for patients with dysplastic BE after successful ablation based on the baseline degree of dysplasia. We could not make recommendations regarding chemoprevention or use of biomarkers in routine practice due to insufficient data.

Abstract
BACKGROUND AND AIMS Current guidelines recommend surveillance for patients with nondysplastic Barrett's esophagus (NDBE) but do not include a recommended age for discontinuing surveillance. This study aimed to determine the optimal age for last surveillance of NDBE patients stratified by sex and level of comorbidity. METHODS We used 3 independently developed models to simulate patients diagnosed with NDBE, varying in age, sex, and comorbidity level (no, mild, moderate, and severe). All patients had received regular surveillance until their current age. We calculated incremental costs and quality-adjusted life-years (QALYs) gained from 1 additional endoscopic surveillance at the current age versus not performing surveillance at that age. We determined the optimal age to end surveillance as the age at which incremental cost-effectiveness ratio of 1 more surveillance was just less than the willingness-to-pay threshold of $100,000/QALY. RESULTS The benefit of having 1 more surveillance endoscopy strongly depended on age, sex, and comorbidity. For men with NDBE and severe comorbidity, 1 additional surveillance at age 80 years provided 4 more QALYs per 1000 patients with BE at an additional cost of $1.2 million, whereas for women with severe comorbidity the benefit at that age was 7 QALYs at a cost of $1.3 million. For men with no, mild, moderate, and severe comorbidity, the optimal ages of last surveillance were 81, 80, 77, and 73 years, respectively. For women, these ages were younger: 75, 73, 73, and 69 years, respectively. CONCLUSIONS Our comparative modeling analysis illustrates the importance of considering comorbidity status and sex when deciding on the age to discontinue surveillance in patients with NDBE.

Abstract
Esophageal cancer (EC) often cannot be discovered in time because of its asymptomatic or symptom-atypical characteristics in early stage. The risk and probability of lymph node metastasis and distant metastasis increase correspondingly as the cancer aggressively invades deeper layers. Treatment regimens may be shifted to surgery and chemoradiotherapy (CRT) from endoscopic eradication therapy (EET) with poor quality of life and prognosis. It is imperative to identify dysplasia and EC early and enable early curative endoscopic treatments. Newer methods have been attempted in the clinical setting to achieve early detection at a more microscopic and precise level. Newer imaging techniques and artificial intelligence (AI) technology have been involved in targeted biopsies and will gradually unveil the visualization of pathology in the future. Early detection and diagnosis are the prerequisite to choose personal and precise treatment regimens. EET has also been undergoing development and improvement to benefit more patients as the first option or the firstly chosen alternative therapy, when compared with esophagectomy. More clinical studies are needed to provide more possibilities for EET.

Comparative Cost Effectiveness of Reflux-Based and Reflux-Independent Strategies for Barrett's Esophagus Screening. Am J Gastroenterol 2021; 116:1620-1631. [PMID: 34131096 PMCID: PMC8315187 DOI: 10.14309/ajg.0000000000001336] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 05/12/2021] [Indexed: 02/07/2023]
Abstract
INTRODUCTION Minimally invasive tests for Barrett's esophagus (BE) detection have raised the prospect of broader nonreflux-based testing. Cost-effectiveness studies have largely studied men aged 50 years with chronic gastroesophageal reflux disease (GERD) symptoms. We evaluated the comparative cost effectiveness of BE screening tests in GERD-based and GERD-independent testing scenarios. METHODS Markov modeling was performed in 3 scenarios in 50 years old individuals: (i) White men with chronic GERD (GERD-based); (ii) GERD-independent (all races, men and women), BE prevalence 1.6%; and (iii) GERD-independent, BE prevalence 5%. The simulation compared multiple screening strategies with no screening: sedated endoscopy (sEGD), transnasal endoscopy, swallowable esophageal cell collection devices with biomarkers, and exhaled volatile organic compounds. A hypothetical cohort of 500,000 individuals followed for 40 years using a willingness to pay threshold of $100,000 per quality-adjusted life year (QALY) was simulated. Incremental cost-effectiveness ratios (ICERs) comparing each strategy with no screening and comparing screening strategies with each other were calculated. RESULTS In both GERD-independent scenarios, most non-sEGD BE screening tests were cost effective. Swallowable esophageal cell collection devices with biomarkers were cost effective (<$35,000/QALY) and were the optimal screening tests in all scenarios. Exhaled volatile organic compounds had the highest ICERs in all scenarios. ICERs were low (<$25,000/QALY) for all tests in the GERD-based scenario, and all non-sEGD tests dominated no screening. ICERs were sensitive to BE prevalence and test costs. DISCUSSION Minimally invasive nonendoscopic tests may make GERD-independent BE screening cost effective. Participation rates for these strategies need to be studied.

Abstract
OBJECTIVES Data from the International Cancer of the Pancreas Screening Consortium studies have demonstrated that screening for pancreatic ductal adenocarcinoma can be effective and that surveillance improves survival in high-risk individuals. Endoscopic ultrasound (EUS) and cross-sectional imaging are both used, although there is some suggestion that EUS is superior. Demonstration of the cost-effectiveness of screening is important to implement screening in high-risk groups. METHODS Results from centers with EUS-predominant screening were pooled to evaluate efficacy of index EUS in screening. A decision analysis model simulated the outcome of high-risk patients who undergo screening and evaluated the parameters that would make screening cost-effective at a US $100,000 per quality-adjusted life-year willingness to pay. RESULTS One-time index EUS has a sensitivity of 71.25% and specificity of 99.82% to detection to detect high-risk lesions. Screening with index EUS was cost-effective, particularly at lifetime pancreatic cancer probabilities of greater than 10.8%, or at lower probabilities if life expectancy after resection of a lesion that was at least 16 years, and if missed, lesion rates on index EUS are 5% or less. CONCLUSIONS Pancreatic cancer screening can be cost-effective through index EUS, particularly for those individuals at high-lifetime risk of cancer.

Abstract
Oesophageal cancer is a global health problem; in 2018 there were more than 572,000 people newly diagnosed with oesophageal cancer worldwide. There are two main histological subtypes of oesophageal cancer, oesophageal adenocarcinoma (EAC) and oesophageal squamous cell carcinoma (ESCC), and there has been a dramatic shift in its epidemiology. While the incidence of EAC and its precursor lesion, Barrett oesophagus, has increased in Western populations over the past four decades, the incidence of ESCC has declined in most parts of the world over the same period. ESCC still accounts for the vast majority of all oesophageal cancer cases diagnosed worldwide each year. Prognosis for patients with oesophageal cancer is strongly related to stage at diagnosis. As most patients are diagnosed with late-stage disease, overall 5-year survival for oesophageal cancer remains <20%. Knowledge of epidemiology and risk factors for oesophageal cancer is essential for public health and clinical decisions about risk stratification, screening and prevention. The goal of this Review is to establish the current epidemiology of oesophageal cancer, with a particular focus on the Western world and the increasing incidence of EAC and Barrett oesophagus.

Abstract
Barrett's esophagus is the precursor lesion for esophageal adenocarcinoma. The goals of endoscopic surveillance are to detect dysplasia and early esophageal adenocarcinoma in order to improve patient outcomes. Despite the ongoing debate regarding the efficacy of surveillance, all current gastrointestinal societies recommend surveillance at this time. Optimal surveillance technique includes adequate inspection time, evaluation using high-definition white light and chromoendoscopy, appropriate documentation of the metaplastic segment using the Prague C & M criteria as well as the Paris classification should lesions be found, utilization of the Seattle biopsy protocol, and endoscopic resection of visible lesions.

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
GOALS To develop an encounter decision aid [Barrett's esophagus Choice (BE-Choice)] for patients and clinicians to engage in shared decision making (SDM) for management of BE with low-grade dysplasia (BE-LGD) and assess its impact on patient-important outcomes. BACKGROUND Currently, there are 2 strategies for management of BE-LGD-endoscopic surveillance and ablation. SDM can help patients decide on their preferred management option. STUDY Phase-I: Patients and clinicians were engaged in a user-centered design approach to develop BE-Choice. Phase-I included review of evidence on BE-LGD management, observation of usual care (UC), creation, field-testing, and iterative development of BE-Choice in clinical settings. Phase-II: Impact of BE-Choice on patient-important outcomes (patient knowledge, decisional conflict, and patient involvement in decision making) was assessed using a controlled before-after study design (UC vs. BE-Choice). RESULTS Phase-I: Initial prototype was designed with observation of 8 clinical encounters. With field-testing, 3 successive iterations were made before finalizing BE-Choice. BE-Choice was paper based and fulfilled the qualifying criteria of International patient decision aid standards. Phase II: 29 patients were enrolled, 8 to UC and 21 to BE-Choice. Compared with UC, use of BE-Choice improved patient knowledge (90.4% vs. 70.5%; P=0.03), decisional comfort (89.6 vs. 71.9; P=0.01), and patient involvement (OPTION score: 27.1 vs. 19.2; P=0.01). CONCLUSIONS BE-Choice is a feasible and effective decision aid to promote SDM in the management of BE-LGD. On pilot testing, BE-Choice had promising impact on patient-important outcomes. A larger multicenter trial is needed to confirm our results and promote widespread use of BE-Choice.

Abstract
The authors conducted a review of the literature of cost-effectiveness analyses regarding management of Barrett's esophagus, including screening, surveillance, and treatment strategies. Because of the presence of multiple systematic reviews on this topic, they chose to focus on more recent economic analyses, with an emphasis on comparative modeling because these analyses have been demonstrated to achieve greater validity and impact when there are multiple competing strategies that are clinically reasonable to pursue. The authors identified areas of consensus across studies regarding management strategies and also areas that require additional empirical data.

Abstract
PURPOSE OF REVIEW Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer associated with increasing incidence and poor survival. Early identification and effective treatment of BE-related neoplasia prior to the development of invasive adenocarcinoma are essential to limiting the morbidity and mortality associated with this cancer. In this review, we summarized the recent evidence guiding endoscopic eradication therapies (EET) for neoplastic BE. RECENT FINDINGS New sampling technologies and the application of artificial intelligence (AI) systems have potential to revolutionize early neoplasia detection in BE. EET for BE are safe and effective in achieving complete eradication of intestinal metaplasia (CE-IM) and reducing the progression to EAC, a practice endorsed by all GI society guidelines. EET should be considered in patients with high-grade dysplasia (HGD), intramucosal carcinoma (IMC), and select cases with low-grade dysplasia (LGD). The increasing use of endoscopic submucosal dissection (ESD) in the West may allow EET of select cases with submucosal EAC. Post-EET surveillance strategies will continue to evolve as knowledge of specific risk factors and long-term neoplasia recurrence rates improve. In the last decade, major advancements in EET for neoplastic BE have been achieved. These now represent the standard of care in the management of BE-related dysplasia and intramucosal cancer.

Abstract
BACKGROUND & AIMS Endoscopic treatment is recommended for patients with Barrett's esophagus (BE) with high-grade dysplasia, yet clinical management recommendations are inconsistent for patients with BE without dysplasia (NDBE) or with low-grade dysplasia (LGD). We used a comparative modeling analysis to identify optimal management strategies for these patients. METHODS We used 3 independent population-based models to simulate cohorts of 60-year-old individuals with BE in the United States. We followed up each cohort until death without surveillance and treatment (natural disease progression), compared with 78 different strategies of management for patients with NDBE or LGD. We determined the optimal strategy using cost-effectiveness analyses, at a willingness-to-pay threshold of $100,000 per quality-adjusted life-year (QALY). RESULTS In the 3 models, the average cumulative incidence of esophageal adenocarcinoma was 111 cases, with costs totaling $5.7 million per 1000 men with BE. Surveillance and treatment of men with BE prevented 23% to 75% of cases of esophageal adenocarcinoma, but increased costs to $6.2 to $17.3 million per 1000 men with BE. The optimal strategy was surveillance every 3 years for men with NDBE and treatment of LGD after confirmation by repeat endoscopy (incremental cost-effectiveness ratio, $53,044/QALY). The average results for women were consistent with the results for men for LGD management, but the optimal surveillance interval for women with NDBE was 5 years (incremental cost-effectiveness ratio, $36,045/QALY). CONCLUSIONS Based on analyses from 3 population-based models, the optimal management strategy for patient with BE and LGD is endoscopic eradication, but only after LGD is confirmed by a repeat endoscopy. The optimal strategy for patients with NDBE is endoscopic surveillance, using a 3-year interval for men and a 5-year interval for women.

Abstract
A cost-utility analysis in the current issue of AJG examines the ramifications of the overuse of surveillance endoscopy in Barrett's esophagus (BE). This study suggests that excess surveillance is expensive, increasing costs by 50% or more, with only nominal increases in quality-adjusted life expectancy. This study joins a growing literature of cost-utility analyses that suggest that more is not likely better when it comes to surveillance endoscopy. Given the plentiful literature showing overutilization of surveillance endoscopy in BE, the authors argue for a focus on the quality of endoscopy rather than increased frequency of surveillance to improve returns on our healthcare investment.

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
Esophageal squamous cell carcinoma and adenocarcinoma account for 95% of all esophageal malignancies. The rates of esophageal adenocarcinoma have increased in Western countries, making it the predominant type of esophageal cancer. Treatment of both types of cancer has transformed to a more minimally invasive approach, with endoscopic methods being used for superficial cancers and more frequent use of video-assisted and laparoscopic modalities for locally advanced tumors. The current National Comprehensive Cancer Network guidelines advocate a trimodal approach to treatment, with neoadjuvant chemoradiation and surgery for locally advanced cancers.

Abstract
BACKGROUND & AIMS Carriers of pathogenic variants in CDH1 have a high risk of hereditary diffuse gastric cancer (HDGC). Guidelines recommend prophylactic total gastrectomy (PTG) at age 20-30 years, although there is controversy over the optimal age. We developed a simulation model to analyze the effects of PTG at different ages on quality-adjusted life-years (QALYs), cancer mortality, and life expectancy. METHODS We used a Markov model of HDGC progression associated with pathogenic variants in CDH1 to simulate outcomes of hypothetical cohorts with different ages at time of PTG (ages 20-79 years). Model inputs including health state transition probabilities, mortality and complication rates, quality of life utility values, and endoscopic surveillance sensitivity were derived from publications. The primary outcome, used to determine the optimal strategy, was age at which PTG yielded the highest QALYs. Secondary outcomes were cancer mortality and unadjusted life-years. RESULTS Our model found that for men, the optimal age for PTG is 39 years, resulting in 32.01 incremental QALYs, 58.81 life-years (biologic age, 72.81 years), and lifetime cancer mortality of 8.5%. Incorporating endoscopic surveillance prior to PTG decreased cancer mortality to 6.7%, but had lower QALYs (31.59). PTG at age 30 reduced cancer mortality to 3.2%, with 31.45 incremental QALYs. For women, the optimal age for PTG was calculated to be 30 years, with 33.09 incremental QALYs, 66.17 life-years (biologic age, 80.17 years), and lifetime cancer mortality of 1.6%. Addition of endoscopic surveillance did not decrease the risk of HDGC mortality in women. CONCLUSIONS Using a Markov model of HDGC progression associated with pathogenic variants in CDH1 to simulate outcomes, we found the optimal ages for PTG to be 39 years for men and 30 years for women, when QALYs are the primary endpoint. These ages for PTG are older than those of current recommendations.

Gastroenterology 2020; 158:760-769. [PMID: 31730766 DOI: 10.1053/j.gastro.2019.09.051] [Citation(s) in RCA: 119] [Impact Index Per Article: 29.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 09/12/2019] [Accepted: 09/16/2019] [Indexed: 12/15/2022]
Abstract
DESCRIPTION The purpose of this best practice advice article is to describe the role of Barrett's endoscopic therapy (BET) in patients with Barrett's esophagus (BE) with dysplasia and/or early cancer and appropriate follow-up of these patients. METHODS The best practice advice provided in this document is based on evidence and relevant publications reviewed by the committee. BEST PRACTICE ADVICE 1: In BE patients with confirmed low-grade dysplasia, a repeat examination with high-definition white-light endoscopy should be performed within 3-6 months to rule out the presence of a visible lesion, which should prompt endoscopic resection. BEST PRACTICE ADVICE 2: Both BET and continued surveillance are reasonable options for the management of BE patients with confirmed and persistent low-grade dysplasia. BEST PRACTICE ADVICE 3: BET is the preferred treatment for BE patients with high-grade dysplasia (HGD). BEST PRACTICE ADVICE 4: BET should be preferred over esophagectomy for BE patients with intramucosal esophageal adenocarcinoma (T1a). BEST PRACTICE ADVICE 5: BET is a reasonable alternative to esophagectomy in patients with submucosal esophageal adenocarcinoma (T1b) with low-risk features (<500-μm invasion in the submucosa [sm1], good to moderate differentiation, and no lymphatic invasion) especially in those who are poor surgical candidates. BEST PRACTICE ADVICE 6: In all patients undergoing BET, mucosal ablation should be applied to 1) all visible esophageal columnar mucosa; 2) 5-10 mm proximal to the squamocolumnar junction and 3) 5-10 mm distal to the gastroesophageal junction, as demarcated by the top of the gastric folds (ie, gastric cardia) using focal ablation in a circumferential fashion. BEST PRACTICE ADVICE 7: Mucosal ablation therapy should only be performed in the presence of flat BE without signs of inflammation and in the absence of visible abnormalities. BEST PRACTICE ADVICE 8: BET should be performed by experts in high-volume centers that perform a minimum of 10 new cases annually. BEST PRACTICE ADVICE 9: BET should be continued until there is an absence of columnar epithelium in the tubular esophagus on high-definition white-light endoscopy and preferably optical chromoendoscopy. In case of complete endoscopic eradication, the neosquamous mucosa and the gastric cardia are sampled by 4-quadrant biopsies. BEST PRACTICE ADVICE 10: If random biopsies obtained from the neosquamous epithelium demonstrate intestinal metaplasia/dysplasia or subsquamous intestinal metaplasia, a repeat endoscopy should be performed and visible islands or tongues should undergo targeted focal ablation. BEST PRACTICE ADVICE 11: Intestinal metaplasia of the gastric cardia (without residual columnar epithelium in the tubular esophagus) should not warrant additional ablation therapy. BEST PRACTICE ADVICE 12: When consenting patients for BET, the most common complication of therapy to be quoted is post-procedural stricture formation, occurring in about 6% of cases. Bleeding and perforation occur at rates <1%. BEST PRACTICE ADVICE 13: After complete eradication (endoscopic and histologic) of intestinal metaplasia has been achieved with BET, surveillance endoscopy with biopsies should be performed at the following intervals: for baseline diagnosis of HGD/esophageal adenocarcinoma: at 3, 6, and 12 months and annually thereafter; and baseline diagnosis of low-grade dysplasia: at 1 and 3 years. BEST PRACTICE ADVICE 14: Endoscopic surveillance post therapy should be performed with high-definition white-light endoscopy, including careful inspection of the neosquamous mucosal and retroflexed inspection of the gastric cardia. BEST PRACTICE ADVICE 15: The approach to recurrent disease is similar to that of the initial therapy; visible recurrent nodular lesions require endoscopic resection, whereas flat areas of columnar mucosa in the tubular esophagus can be treated with mucosal ablation. BEST PRACTICE ADVICE 16: Patients should be counseled on cancer risk in the absence of BET, as well as after BET, to allow for informed decision-making between the patient and the physician.

Abstract
BACKGROUND The incidence of oesophageal adenocarcinoma is increasing globally. Barrett's oesophagus (BO) is a pre-malignant condition with no biomarker to risk stratify those at highest risk of dysplasia and malignant transformation. METHODS Subcellular epithelial protein (HMGB1, p53, RUNX3) expression, alongside expression of CD20, CD4, CD8 and Foxp3 to characterise stromal B lymphocyte, and helper, cytotoxic and regulatory T-lymphocyte cell infiltrate, respectively, was assessed by immunohistochemistry in 218 human tissue samples including normal oesophageal/gastric biopsies (n = 39), BO (non-dysplasia, dysplasia, non-dysplastic background from progressors to dysplasia or cancer, n = 121) and oesophageal adenocarcinoma (n = 58). RESULTS There is a dynamic subcellular epithelial expression of HMGB1 (loss of nuclear, emergence of cytoplasmic), associated with epithelial p53 expression and differential immune cell phenotype in oesophageal neoplastic progression. We identify a protein signature and lymphocyte infiltrate in non-dysplastic BO when progressive disease (dysplasia or adenocarcinoma) is present but not histologically represented in the biopsied field. There is a dynamic stromal lymphocytic infiltrate in oesophageal neoplastic progression. CONCLUSIONS This data reveals novel insights into the microenvironment of BO and progression towards cancer and identifies a novel high-risk biomarker of disease progression to aid surveillance strategies to identify early progression and impact future incidence of oesophageal cancer.

Abstract
Barrett esophagus is found in 5% to 15% of patients with gastroesophageal reflux disease and is a precursor of esophageal adenocarcinoma, yet the condition often goes undiagnosed. Patients with reflux disease who are male, over age 50, or white, and who smoke or have central obesity or a family history of Barrett esophagus or esophageal adenocarcinoma, should undergo initial screening endoscopy and, if no dysplasia is noted, surveillance endoscopy every 3 to 5 years. Dysplasia is treated with endoscopic eradication by ablation, resection, or both. Chemoprotective agents are being studied to prevent progression to dysplasia in Barrett esophagus. The authors discuss current recommendations for screening and management.

CLINICOECONOMICS AND OUTCOMES RESEARCH 2019; 11:623-635. [PMID: 31749626 PMCID: PMC6818671 DOI: 10.2147/ceor.s221741] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 10/02/2019] [Indexed: 12/18/2022] Open
Abstract
PURPOSE This study evaluates the cost-effectiveness of a quantitative multi-biomarker assay (the Assay) that stratifies patients with Barrett's Esophagus (BE) by risk of progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) and can be used to guide clinical decisions, versus the current guidelines (standard of care [SOC]) for surveillance and treatment of BE. PATIENTS AND METHODS Markov decision modeling and simulation were used to compare cost and quality-adjusted life-years (QALYs) from the perspective of a US health insurer with care delivered by an integrated health system. Model assumptions and disease progression probabilities were derived from the literature. Performance metrics for the Assay were from an independent clinical validation study. Cost of the Assay was based on reimbursement rates from multiple payers. Other costs were derived from Geisinger payment data. RESULTS Base-case model results for a 5-year period comparing the Assay-directed care to the SOC estimated an incremental cost-effectiveness ratio (ICER) of $52,483/QALY in 2012 US dollars. Assay-directed care increased the use of endoscopic treatments by 58.4%, which reduced the progression to HGD, EAC and reduced EAC-related deaths by 51.7%, 47.1%, and 37.6%, respectively, over the 5-year period. Sensitivity analysis indicated that the probability of the Assay being cost-effective compared to the SOC was 57.3% at the $100,000/QALY acceptability threshold. CONCLUSION Given the model assumptions, the new Assay would be cost-effective after 5 years and improves patient outcomes due to improvement in the effectiveness of surveillance and treatment protocols resulting in fewer patients progressing to HGD and EAC and fewer EAC-related deaths.

Abstract
Esophageal cancer (EC) generally consists of squamous cell carcinoma (which arise from squamous epithelium) and adenocarcinoma (which arise from columnar epithelium). Due to the increased recognition of risk factors associated with EC and the development of screening programs, there has been an increase in the diagnosis of early EC. Early EC is amenable to curative therapy by endoscopy, which can be performed by either endoscopic resection or endoscopic ablation. Endoscopic resection consists of either endoscopic mucosal resection (preferred in cases of adenocarcinoma) or endoscopic submucosal dissection (preferred in cases of squamous cell carcinoma). Endoscopic ablation can be performed by either radiofrequency ablation, cryotherapy, argon plasma coagulation or photodynamic therapy, amongst others. Endoscopy can also assist in the management of complications post-esophageal surgery, such as anastomotic leaks and perforations. Finally, there is a growing role for endoscopy to manage end-of-life palliative symptoms, especially dysphagia. The growing use of esophageal stents, debulking therapy and dilation can assist in improving a patient’s quality of life. In this review, we examine the multiple roles of endoscopy in the management of patients with EC.

Abstract
BACKGROUND Detailed cost estimates are not widely available for esophageal cancer. Our study estimates phase-specific costs for esophageal cancer by age, year, histology, stage, and treatment for older patients in the United States and compares these costs within stage and treatment modalities. METHODS We identified 8061 esophageal cancer patients in the Surveillance, Epidemiology, and End Results-Medicare database for years 1998-2013. Total, cancer-attributable, and patient-liability costs were calculated based on separate phases of care-staging (or surgery), initial, continuing, and terminal. We estimated costs by treatment modality within stage and phase for esophageal adenocarcinoma and squamous cell carcinoma separately. We fit linear regression models using log transformation to determine cost by age and calendar year. All costs are reported in 2018 US dollars. RESULTS Overall, mean (95% CI) monthly total cost estimates were high during the staging ($8953 [$8385-$9485]) and initial phases ($7731 [$7492-$7970]), decreased over the continuing phase ($2984 [$2814-$3154]), and increased substantially during the 6-month terminal phase ($18 150 [$17 211-$19 089]). This pattern of high staging and initial phase costs, decreasing continuing phase costs, and increasing terminal phase costs was seen in all stages. The highest staging costs were in stages III ($9249, $8025-$10 474) and II ($9171, $7642-$10 699). The highest initial phase cost was in stage IV, $9263 ($8758-49 768), the lowest continuing phase cost was in stage I, $2338 ($2160-$2517), and the highest terminal phase costs were in stages II ($20 533, $17 772-$23 293) and III ($20 599, $18 268-$22 929). The linear regression models showed that cancer-attributable costs remained stable over the study period and were unaffected by age for most histology, stage, and treatment modality subgroups. CONCLUSIONS Our estimates demonstrate that esophageal cancer costs can vary widely by histology, stage, and treatment. These cost estimates can be used to guide future resource allocation for esophageal cancer care and research.

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
In predisposed individuals with long standing gastroesophageal reflux disease (GERD), esophageal squamous mucosa can transform into columnar mucosa with intestinal metaplasia, commonly called Barrett’s esophagus (BE). Barrett’s mucosa can develop dysplasia, which can be a precursor for esophageal adenocarcinoma (EAC). However, most EAC cases are identified when esophageal symptoms develop, without prior BE or GERD diagnoses. While several gastrointestinal societies have published BE screening guidelines, these vary, and many recommendations are not based on high quality evidence. These guidelines are concordant in recommending targeted screening of predisposed individuals (eg, long standing GERD symptoms with age > 50 years, male sex, Caucasian race, obesity, and family history of BE or EAC), and against population based screening, or screening of GERD patients without risk factors. Targeted endoscopic screening programs provide earlier diagnosis of high grade dysplasia and EAC, and offer potential for endoscopic therapy, which can improve prognosis and outcome. On the other hand, endoscopic screening of the general population, unselected GERD patients, patients with significant comorbidities or patients with limited life expectancy is not cost-effective. New screening modalities, some of which do not require endoscopy, have the potential to reduce costs and expand access to screening for BE.

Abstract
BACKGROUND AND AIMS Barrett's esophagus (BE) screening is currently not considered to be cost effective in the general population but may be effective in high-risk subgroups, such as 50-year-old white men with chronic reflux disease (GERD). A new modality for screening is unsedated transnasal endoscopy using endosheath technology (uTNE), which has been shown to be safe and effective in clinical practice. In this study, we determined the cost-utility of uTNE in a high-risk subgroup compared with no screening or screening with standard endoscopy. METHODS A Markov model was used to simulate screening of 50-year-old white men with symptoms of GERD with either uTNE or standard endoscopy compared with no screening, over a lifetime horizon. Input variables were based on the literature and recent data on uTNE screening for BE. The study was designed from a healthcare payer perspective by using direct costs. Primary outcome measures were costs, quality-adjusted life years (QALYs), and the incremental cost-utility ratio (ICUR) of uTNE and standard endoscopy compared with no screening. Sensitivity analysis was performed for several factors, such as prevalence of BE. RESULTS Costs of uTNE, standard endoscopy, and no screening were estimated at, $2495, $2957, and $1436, respectively. Compared with no screening, uTNE screening resulted in an overall QALY increase of 0.039 (95% percentile 0.018; 0.063) and an ICUR of $29,446 per QALY gained (95% confidence interval [CI], 18.516-53.091), whereas standard endoscopy compared with no screening resulted in a QALY increase of 0.034 (95% CI, 0.015-0.056) and an ICUR of $47,563 (95% CI, 31,036-82,970). CONCLUSION Both uTNE and standard endoscopy seem to be cost-effective screening methods in a screening cohort of 50-year-old white men with GERD at a willingness-to-pay cutoff of $50,000.

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
Since Barrett’s esophagus is a precancerous condition, efforts have been made for its eradication by various ablative techniques. Initially, laser ablation was attempted in non-dysplastic Barrett’s esophagus and subsequently, endoscopic ablation using photodynamic therapy was used in Barrett’s patients with high-grade dysplasia who were poor surgical candidates. Since then, various ablative therapies have been developed with radiofrequency ablation having the best quality of evidence. Resection of dysplastic areas only without complete removal of entire Barrett’s segment is associated with high risk of developing metachronous neoplasia. Hence, the current standard of management for Barrett’s esophagus includes endoscopic mucosal resection of visible abnormalities followed by ablation to eradicate remaining Barrett’s epithelium. Although endoscopic therapy cannot address regional lymph node metastases, such nodal involvement is present in only 1% to 2% of patients with intramucosal adenocarcinoma in Barrett esophagus and therefore is useful in intramucosal cancers. Post ablation surveillance is recommended as recurrence of intestinal metaplasia and dysplasia have been reported. This review includes a discussion of the technique, efficacy and complication rate of currently available ablation techniques such as radiofrequency ablation, cryotherapy, argon plasma coagulation and photodynamic therapy as well as endoscopic mucosal resection. A brief discussion of the emerging technique, endoscopic submucosal dissection is also included.

Abstract
The exponential rise in incidence of esophageal adenocarcinoma (EAC), paired with persistently poor survival, continues to drive efforts to improve and optimize screening and surveillance practices. While advancements in endoscopic therapy have generated a shift in management and significantly improved the outcomes of patients with early-stage EAC, the majority of prevalent EAC continues to be diagnosed at advanced stages, remaining ineligible for curative therapy. Barrett's esophagus (BE) screening, when applied to high-yield target populations, using minimally or noninvasive accurate tests, followed by endoscopic surveillance to detect prevalent or incident dysplasia/EAC (which can then be treated successfully) is the cornerstone of the current BE management paradigm. While supported by some empiric evidence and attractive, this approach faces a number of challenges, which are also balanced by numerous recent advances in these areas. In this manuscript, we review the rationale, supportive evidence, current challenges, and recent progress in BE screening and surveillance.

Abstract
The cost-effectiveness of screening and surveillance for Barrett's esophagus continues to evolve as the incidence of esophageal adenocarcinoma increases, biomarkers enhance the identification of individuals at highest risk for developing cancer, and endoscopic eradication of Barrett's esophagus improves. Screening to detect Barrett's esophagus may be cost-effective in selected high-risk groups based on age, race, sex and other factors such as symptoms of heartburn. Currently, endoscopic eradication therapy for Barrett's esophagus and high-grade dysplasia is a cost-effective intervention, while endoscopic therapy for non-dysplastic Barrett's esophagus is not a cost-effective strategy. As diagnosis of low-grade dysplasia improves, endoscopic eradication therapy may also prove to be a cost-effective intervention.

Abstract
The currently recommended approach to managing cancer risk for patients with Barrett's esophagus is endoscopic surveillance including a biopsy protocol to sample the esophageal tissue randomly to detect dysplasia. However, there are numerous limitations in this practice that rely on the histopathological grading of dysplasia alone to make clinical decisions. The availability of in silico models demonstrating the potential cost-effectiveness of biomarker-based stratification has increased interest in finding a clinically relevant "Barrett's biomarker." The success of endoscopic eradication therapy in preventing neoplastic progression of dysplastic Barrett's esophagus has promoted the desire to stratify non-dysplastic Barrett's esophagus to those with "high risk" that may benefit from endotherapy. Furthermore, on the other end of the spectrum, there is interest in searching for a "low risk" marker that may identify those that would not likely benefit from endoscopy screening or surveillance. This review highlights recent data from the genomics (r)evolution revealing new genetic biomarkers of susceptibility to the development of Barrett's esophagus and novel pathways for its neoplastic progression, addresses the development of new modes of tissue sampling and imaging to detect early neoplasia in Barrett's esophagus, and discusses current progress in moving biomarkers from the laboratory into clinical practice in the era of precision medicine.

Abstract
Despite esophageal adenocarcinoma (EAC) being the most widespread among gastrointestinal cancers, with an 11-fold increase in the risk of cancer for patients with Barrett esophagus (BE), its prognosis is still poor. There is a critical need to better perceive the biology of cancer progression and identification of specific targets that are the hallmark of BE's progression. This review explores the established animal models of BE, including genetic, surgical and nonsurgical approaches, potential chemoprevention targets, and the reasoning behind their applications to prevent Barrett-related EAC. The key methodological features in the design feasibility of relevant studies are also discussed. Cancer Res; 78(14); 3747-54. ©2018 AACR.

Abstract
Esophageal adenocarcinoma (EAC) arising on Barrett esophagus (BE) has become the most frequent type of esophageal malignancy in the Western world. BE is a frequent condition but progression to EAC is rare. Scientific societies publish guidelines in order to improve patients' care. However, there are fields where evidence is lacking or there are many controversies. We aimed to spotlight the most important changes, as well as the points of controversy in the recently published guidelines for BE. For most, a length ≥1 cm of a salmon-pink mucosa extending above the eso-gastric junction is required in order to define BE, accompanied with the presence of intestinal metaplasia (IM) at histology. Screening with endoscopy for the general population is not recommended while there is no proof of the efficacy of screening for targeted high risk populations. New techniques permitting a cytologic examination are under evaluation and may change this strategy. The use of high-resolution endoscopes coupled with a careful inspection of the mucosa are required during surveillance of BE. New studies are necessary in order to clarify the real benefit from the use of advanced techniques, such as virtual chromoendoscopy. Length of non-dysplastic BE plays a role for the interval time determination between endoscopies during surveillance. Indefinite for dysplasia and even more low grade dysplasia (LGD) are debatable issues in the matter of BE. There are compelling data suggesting that a definite LGD, defined as a permanent lesion confirmed by a specialist pathologist in BE, has a more dismal prognosis than previously reported and an ablative intervention may be offered in this case. However, most (75-85%) cases with LGD were downstaged in published studies and it remains unknown if in real life, percentages of downstaging are approaching those of studies or there is an over-treatment of pseudo-LGD. Biomarkers such as p53 immunohistochemistry may aid better identification of patients at higher risk. For high grade dysplasia (HGD) visible lesions should be resected with Endoscopic Mucosal Resection (EMR) while flat lesions ablated, for most, nowadays, with radiofrequency ablation (RFA). Endoscopic submucosal dissection (ESD) has not proved superior compared to EMR in BE. It has to be underlined that most studies leading to the new guidelines for BE are not considered of high quality and new guidelines may emerge in the near future.

Abstract
BACKGROUND Esophageal adenocarcinoma (EAC) incidence is increasing rapidly. Esophageal cancer has the second lowest 5-year survival rate of people diagnosed with cancer in Canada. Given the poor survival and the potential for further increases in incidence, phase-specific cost estimates constitute an important input for economic evaluation of prevention, screening, and treatment interventions. The study aims to estimate phase-specific net direct medical costs of care attributable to EAC, costs stratified by cancer stage and treatment, and predictors of total net costs of care for EAC. METHODS A population-based retrospective cohort study was conducted using Ontario Cancer Registry-linked administrative health data from 2003 to 2011. The mean net costs of EAC care per 30 patient-days (2016 CAD) were estimated from the payer perspective using phase of care approach and generalized estimating equations. Predictors of net cost by phase of care were based on a generalized estimating equations model with a logarithmic link and gamma distribution adjusting for sociodemographic and clinical factors. RESULTS The mean net costs of EAC care per 30 patient-days were $1016 (95% CI, $955-$1078) in the initial phase, $669 (95% CI, $594-$743) in the continuing care phase, and $8678 (95% CI, $8217-$9139) in the terminal phase. Overall, stage IV at diagnosis and surgery plus radiotherapy for EAC incurred the highest cost, particularly in the terminal phase. Strong predictors of higher net costs were receipt of chemotherapy plus radiotherapy, surgery plus chemotherapy, radiotherapy alone, surgery alone, and chemotherapy alone in the initial and continuing care phases, stage III-IV disease and patients diagnosed with EAC later in a calendar year (2007-2011) in the initial and terminal phases, comorbidity in the continuing care phase, and older age at diagnosis (70-74 years), and geographic region in the terminal phase. CONCLUSIONS Costs of care vary by phase of care, stage at diagnosis, and type of treatment for EAC. These cost estimates provide information to guide future resource allocation decisions, and clinical and policy interventions to reduce the burden of EAC.

Abstract
Background We aim to investigate factors that may contribute to failure of eradication of dysplastic Barrett’s Esophagus among patients undergoing radiofrequency ablation treatment. Methods A retrospective review of patients undergoing radiofrequency ablation for treatment of Barrett’s Esophagus was performed. Data analyzed included patient demographics, medical history, length of Barrett’s Esophagus, number of radiofrequency ablation sessions, and histopathology. Subsets of patients achieving complete eradication were compared with those not achieving complete eradication. Results A total of 107 patients underwent radiofrequency ablation for Barrett’s Esophagus, the majority white, overweight, and male. Before treatment, 63 patients had low-grade dysplasia, and 44 patients had high-grade dysplasia or carcinoma. Complete eradication was achieved in a majority of patients (57% for metaplasia, and 76.6% for dysplasia). Failure of eradication occurred in 15.7% of patients. The median number of radiofrequency ablation treatments in patients achieving complete eradication was 3 sessions, compared to 4 sessions for failure of eradication (p = 0.06). Barrett’s esophagus length of more than 5 cm was predictive of failure of eradication (p < 0.001). Conclusions Radiofrequency ablation for dysplastic Barrett’s Esophagus is a proven and effective treatment modality, associated with a high rate of complete eradication. Our rates of eradication from a center starting an ablation program are comparable to previously published studies. Length of Barrett’s segment > 5 cm was found to be predictive of failure of eradication in patients undergoing radiofrequency ablation.

Abstract
Advances in endoscopic eradication therapy for Barrett's Esophagus-associated neoplasia have resulted in a significant paradigm shift in the diagnosis and management of this complex disease. A robust body of literature critically evaluating outcomes of resection and ablative strategies has allowed gastroenterologists to make quality, evidence-based decisions for their patients. Despite this progress, there are still many unanswered questions and challenges that remain. Ultimately, identification of a cost-effective screening modality, biomarkers for risk stratification, and strides to eliminate post surveillance endoscopy after endoscopic eradication therapy are essential to reach our long-term goal for eradication of esophageal adenocarcinoma.

Abstract
BACKGROUND AND STUDY AIMS To assess the cost-effectiveness of introducing endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection in selected patients into the standard of care of Barrett's esophagus patients with high-grade dysplasia or low-grade dysplasia in Spain. METHODS The disease evolution was modeled via a semi-Markov model. The treatment strategies compared included endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection and the Standard of Care (esophagectomy or palliative chemoradiotherapy according to disease status for high-grade dysplasia and endoscopic surveillance for low-grade dysplasia). Efficacy rates, transition probabilities and utility values were obtained from the literature. Clinical management patterns and resource use were modeled according to Spanish clinical expert opinion. Costs were expressed in euros (€) from 2016 reflecting the Spanish National Health System perspective. Sensitivity analyses were performed to assess the robustness of the model. RESULTS With respect to the Spanish Standard of Care, endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection was a dominant strategy for high-grade dysplasia patients. When a willingness-to-pay threshold of €30,000 per quality-adjusted life-years gained was considered, this was cost-effective for low-grade dysplasia patients (€12,865 per quality-adjusted life-years gained). The sensitivity analyses supported the base case analysis results and pointed towards the main drivers of uncertainty in the model. CONCLUSIONS From a health care decision-maker, endoscopic treatment based on radiofrequency ablation plus endoscopic mucosal resection is the intervention of choice for dysplasic Barrett's esophagus patients in Spain.

Abstract
PURPOSE OF REVIEW In this review, we discuss different endoscopic techniques in the eradication of Barrett's esophagus (BE) as well as some controversies in the field of treatment. RECENT FINDINGS Patients with T1a esophageal adenocarcinoma and BE of high-grade dysplasia should undergo endoscopic ablative therapy. The most studied technique to date is radiofrequency ablation. It can be combined with endoscopic mucosal resection in cases containing nodular and flat lesions. Cryotherapy and APC have shown promise with good efficacy and safety profiles so far, but are not mainstream as more studies are needed. Surveillance is still required post-ablation since recurrence is common. Low-grade dysplasia can be treated with either endo-ablative therapy or surveillance. Non-dysplastic BE treatment is controversial and so far, only surveillance is recommended. Research is ongoing to better risk stratify these patients. Our ability to diagnose and treat BE has come a long way in the past few years with the goal of preventing its progression into malignancy. The advent of endoscopic techniques in the eradication of BE has provided a less invasive and safer modality of treatment as compared to surgical esophagectomy. Data in the form of randomized trials and high-volume registries has provided good evidence to support the efficacy of these techniques and their long-term durability.
