Abstract
Early detection of dysplasia and effective management are critical steps in halting neoplastic progression in patients with Barrett's esophagus (BE). This review provides a contemporary overview of the BE-related dysplasia, its role in guiding surveillance and management, and discusses emerging diagnostic and therapeutic approaches that might further enhance patient management. Novel, noninvasive techniques for sampling and surveillance, adjunct biomarkers for risk assessment, and their limitations are also discussed.

Abstract
Achalasia and Treatment of esophageal Adenocarcinoma are commonly associated to surgical resection. Newer technologies in interventional endoscopy gave way to a substantial paradigm shift in the management of these conditions. In the case of achalasia, endoscopic myotomy is rapidly displacing Heller's myotomy as the gold standard in many centers. Early stage neoplasia in Barrett's esophagus (BE) comprising high-grade dysplasia (HGD), intramucosal and, in some cases, submucosal carcinoma is now being treated without the need of esophagectomy. This review presents a summary of the most relevant endoscopic techniques for both achalasia and esophageal cancer. Endoscopic advances in diagnostic and therapeutic arenas allow for minimally invasive therapies and organ preservation in most settings of achalasia and early stage neoplasia of the esophagus provided that the clinical setting and physician's expertise are prepared for this approach.

Abstract
Incidence of oesophageal adenocarcinoma has increased exponentially in the West over the past few decades. Following detection of advanced cancers, 5-year survival rates remain bleak, making identification of early neoplasia, which has a better outcome, important. Detection of subtle oesophageal lesions during endoscopy can be challenging, and advanced imaging techniques might improve their detection. High-definition endoscopy has become a standard in most endoscopy centres, and this technology probably provides better delineation of mucosal features than standard-definition endoscopy. Various image enhancement techniques are now available with the development of new electronics and software systems. Image enhancement with chromoendoscopy using dyes has been a cost-effective option for many years, yet these techniques have been replaced in some contexts by electronic chromoendoscopy, which can be used with the press of a button. However, Lugol's chromoendoscopy remains the gold standard to identify squamous dysplasia. Identification and characterization of subtle neoplastic lesions could help to target biopsies and perform endoscopic resection for better local staging and definitive therapy. In vivo histology with techniques such as confocal endomicroscopy could make endotherapy feasible within a shorter timescale than when relying on histology on tissue samples. Once early neoplasia is identified, treatments include endoscopic resection, endoscopic submucosal dissection or various ablative techniques. Endotherapy has the advantage of being a less invasive technique than oesophagectomy, and is associated with lower mortality and morbidity. Endoscopic ablation therapies have evolved over the past few years, with radiofrequency ablation showing the best results in terms of success rates and complications in Barrett dysplasia.

Abstract
Esophageal cancer is the eighth most common cancer worldwide. Esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) are the two major phenotypes in Western and Eastern countries, respectively. Because of different pathways in carcinogenesis, the risk factors and effective steps for prevention of esophageal cancer are different between EAC and ESCC. The carcinogenesis of EAC is initiated by the acid exposure of the esophageal mucosa from stomach while that of the ESCC are related to the chronic irritation of carcinogens mainly by the alcohol, cigarette, betel quid, and hot beverage. To eliminate the burden of esophageal cancer on the global health, the effective strategy should be composed of the primary, secondary, and tertiary prevention. In this article, we perform a systematic review of the preventive strategies for esophageal cancer with special emphasis on the differences from the perspectives of Western and Eastern countries.

Abstract
Management of esophageal cancer has evolved since the two last decades. Esophagectomy remains the primary treatment for early stage esophageal cancer although its specific role in superficial cancers is still under debate since the development of endoscopic mucosal treatment. To date, there is strong evidence to consider that locally advanced cancers should be recommended for a multimodal treatment with a neoadjuvant chemotherapy or a combined chemoradiotherapy (CRT) followed by surgery. For locally advanced squamous cell carcinoma or for a part of adenocarcinoma, some centers have proposed treating with definitive CRT to avoid related-mortality of surgery. In case of persistent or recurrent disease, a salvage esophagectomy remains a possible option but this procedure is associated with higher levels of perioperative morbidity and mortality. Despite the debate over what constitutes the best surgical approach (transthoracic versus transhiatal), the current question is if a minimally procedure could reduce the periopertive morbidity and mortality without jeopardizing the oncological results of surgery. Since the last decade, minimally invasive esophagectomy (MIE) or hybrid operations are being done in up to 30% of procedures internationally. There are some consistent data that MIE could decrease the incidence of the respiratory complications and decrease the length of hospital-stay. Nowadays, oncologic outcomes appear equivalent between open and minimally invasive procedures but numerous phase III trials are ongoing.

Abstract
BACKGROUND With recent advances in endoscopy, endoscopic techniques have surpassed esophagectomy in the treatment of dysplastic Barrett's esophagus (BE). OBJECTIVE To compare the efficacy and safety of complete EMR and radiofrequency ablation (RFA) in the treatment of dysplastic BE. DESIGN Systematic review of literature. PATIENTS Diagnosis of BE with high-grade dysplasia or intramucosal cancer. INTERVENTION Complete EMR or RFA. MAIN OUTCOME MEASUREMENTS Complete eradication of dysplasia and intestinal metaplasia at the end of treatment and after >12 months' follow-up. Adverse event rates associated with treatment. RESULTS A total of 22 studies met the inclusion criteria. Only 1 trial directly compared the 2 techniques; most studies were observational case series. Dysplasia was effectively eradicated at the end of treatment in 95% of patients after complete EMR and 92% after RFA. After a median follow-up of 23 months for complete EMR and 21 months for RFA, eradication of dysplasia was maintained in 95% of patients treated with complete EMR and 94% treated with RFA. Short-term adverse events were seen in 12% of patients treated with complete EMR but in only 2.5% of those treated with RFA. Esophageal strictures were adverse events in 38% of patients treated with complete EMR, compared with 4% of those treated with RFA. Progression to cancer appeared to be rare after treatment, although follow-up was short. LIMITATIONS Small studies, heterogeneous in design, with variable outcome measures. Also follow-up durations were short, limiting evaluation of long-term durability of both treatments. CONCLUSION RFA and complete EMR are equally effective in the short-term treatment of dysplastic BE, but adverse event rates are higher with complete EMR.

Abstract
The management of Barrett's oesophagus and associated neoplasia has evolved considerably in recent years. Modern endoscopic strategies including endoscopic resection and mucosal ablation can eradicate dysplastic Barrett's and prevent progression to invasive oesophageal cancer. However, several aspects of Barrett's management remain controversial including the stage in the disease process at which to intervene, and the choice of endoscopic or surgical therapy. A review of articles pertaining to the management of Barrett's oesophagus with or without associated neoplasia, was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Medline, Embase and Cochrane databases were searched to identify literature relevant to eight pre-defined areas of clinical controversy. The following search terms were used: Barrett's oesophagus; dysplasia; intramucosal carcinoma; endotherapy; endoscopic resection; ablation; oesophagectomy. A significant body of evidence exists to support early endoscopic therapy for high-grade dysplasia (HGD). Although not supported by randomised controlled trial evidence, endoscopic therapy is now favoured ahead of oesophagectomy for most patients with HGD. Focal intramucosal (T1a) carcinomas can be managed effectively using endoscopic and surgical therapy, however surgery should be considered the first line therapy where there is submucosal invasion (T1b). Treatment of low grade dysplasia is not supported at present due to widespread over-reporting of the disease. The role of surveillance endoscopy in non-dysplastic Barrett's remains controversial.

Abstract
BACKGROUND Treatment of esophageal adenocarcinoma often involves surgical resection. Newer technologies in interventional endoscopy have led to a substantial paradigm shift in the management of early-stage neoplasia in Barrett's esophagus comprising high-grade dysplasia (HGD), intramucosal carcinoma, and, in some cases, submucosal carcinoma. However, there has been no consensus regarding the indications for esophageal preservation in these cases. In this work, consensus guidelines were established for the management of early-stage esophageal neoplasia considering clinically relevant aspects (age, comorbidities, and social environment) in each scenario. METHODS Seventeen experts were invited to participate based on their background and clinical expertise at high-volume centers. A questionnaire was created that included four clinical scenarios covering a wide range of situations within HGD and/or early esophageal neoplasia, particularly where controversies are likely to exist. Each of the clinical scenarios was open to discussion subdivided by patient age (20, 50, and 80 s). For each clinical scenario an expert was chosen to defend that position. Each defense triggered a subsequent discussion during a consensus meeting. Conclusions of that discussion together with an accompanying literature analysis allowed experts to confirm or change their original choices and served as the basis for the recommendations stated in this article. RESULTS There was 100 % consensus supporting esophageal preservation in patients with HGD, independent of patient age or Barrett's length. In patients with T1a adenocarcinoma, consensus for preservation was not reached (65 %) for young and middle-aged individuals but was supported for elderly patients (100 %). For T1b adenocarcinoma, consensus was reached for surgical resection (90 %), leaving organ preservation for patients with very low risk of nodal invasion or poor surgical candidates. CONCLUSION Advances in endoscopic imaging and therapy allow for organ preservation in most settings of early-stage neoplasia of the esophagus, provided that the patient understands the implications of this decision.

Abstract
Background Barrett's esophagus (BE) is the most important identifiable risk factor for the progression to esophageal adenocarcinoma. Methods This article reviews the current endoscopic therapies for BE with high-grade dysplasia and intramucosal cancer and briefly discusses the endoscopic palliation of advanced esophageal cancer. Results The diagnosis of low-grade or high-grade dysplasia (HGD) is based on several cytologic criteria that suggest neoplastic transformation of the columnar epithelium. HGD and carcinoma in situ are regarded as equivalent. The presence of dysplasia, particularly HGD, is also a risk factor for synchronous and metachronous adenocarcinoma. Dysplasia is a marker of adenocarcinoma and also has been shown to be the preinvasive lesion. Esophagectomy has been the conventional treatment for T1 esophageal cancer and, although debated, is an appropriate option in some patients with HGD due to the presence of occult cancer in over one-third of patients. Conclusions Endoscopic ablative modalities (eg, photodynamic therapy and cryoablation) and endoscopic resection techniques (eg, endoscopic mucosal resection) have demonstrated promising results. The significant morbidity and mortality of esophagectomy makes endoscopic treatment an attractive potential option.

Abstract
Radiofrequency ablation (RFA) with HALO system has been developed as a new treatment option for Barrett's esophagus (BE). It had been observed that some patients had esophageal eosinophilia (EE) infiltration after RFA. The incidence and features of EE after RFA were systematically determined. From a prospectively compiled database, data on 148 patients who underwent RFA for BE were analyzed. Biopsies were taken pre- and post-RFA from the BE segment, and histological sections of the biopsy specimens were stained with hematoxylin and eosin, and examined by a gastrointestinal pathologist. The incidence of EE post-RFA was then determined. Of the 148 patients, 120 (81%) were men, 137 (92%) were white, 64 (43%) were overweight and 49 (33%) obese, and 128 (86%) were over 50 years of age or more. Four (2.7%) of the patients developed post-RFA EE, but none had symptoms of eosinophilic esophagitis. All patients except one had a history of seasonal allergies. All four were taking proton pump inhibitor before and after RFA. Two patients with EE drank alcohol, one of which was a smoker. EE is a potential adverse event of RFA for BE. The absence of esophageal dysfunction symptoms suggests a different clinicopathological entity from eosinophilic esophagitis. Further studies should be done to assess its clinical significance, if therapy is needed, or if it may eventually lead to eosinophilic esophagitis.

Abstract
The need to combat the rising incidence of esophageal adenocarcinoma with its dismal prognosis has led to increasing development of many endoscopic treatments for Barrett's esophagus (BE). Radiofrequency ablation (RFA) has been shown to be a safe and effective endoscopic treatment modality for dysplastic BE. The durability of successful eradication of dysplastic BE has been reported by earlier studies with limited sample size, follow-up time, and inadequate cohort of patients with high-grade dysplasia or intramucosal cancer. In this issue, Orman and colleagues present their findings from their single center, retrospective cohort of patients who underwent RFA with post-treatment surveillance. They report a low recurrence rate of 5.2% per year. There were no clinical characteristics found to be associated with BE recurrence in terms of length of segment or degree of dysplasia. Complete eradication of dysplasia (CE-D) or intestinal metaplasia was determined after a single post-RFA endoscopic examination with biopsies. This is an area of controversy as previous studies have used a minimum of two negative examinations before CE can be claimed. There are also limitations from sampling error during surveillance biopsies and the loss of a third of all post-RFA patients during surveillance. Multicenter, prospective studies with adequate follow-up are still needed before we can draw recommendations when to adequately cease post-treatment surveillance and to identify patients with increased risk of either recurrence or progression.

Abstract
Advances in endoscopic therapy have resulted in dramatic changes in the way early esophageal cancer is managed as well as in the palliation of dysphagia related to advanced esophageal cancer. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are effective therapies for accurate histopathologic staging and provide a potential for complete cure. Mucosal ablative techniques (radiofrequency ablation and cryotherapy) are effective adjuncts to EMR and ESD and reduce the occurrence of synchronous and metachronous lesions within the Barrett esophagus. The successes of these techniques have made endoscopic therapy the primary means of management of early esophageal cancer.

Abstract
BACKGROUND & AIMS Esophageal adenocarcinoma (EA) is increasingly common among patients with Barrett's esophagus (BE). We aimed to provide consensus recommendations based on the medical literature that clinicians could use to manage patients with BE and low-grade dysplasia, high-grade dysplasia (HGD), or early-stage EA. METHODS We performed an international, multidisciplinary, systematic, evidence-based review of different management strategies for patients with BE and dysplasia or early-stage EA. We used a Delphi process to develop consensus statements. The results of literature searches were screened using a unique, interactive, Web-based data-sifting platform; we used 11,904 papers to inform the choice of statements selected. An a priori threshold of 80% agreement was used to establish consensus for each statement. RESULTS Eighty-one of the 91 statements achieved consensus despite generally low quality of evidence, including 8 clinical statements: (1) specimens from endoscopic resection are better than biopsies for staging lesions, (2) it is important to carefully map the size of the dysplastic areas, (3) patients that receive ablative or surgical therapy require endoscopic follow-up, (4) high-resolution endoscopy is necessary for accurate diagnosis, (5) endoscopic therapy for HGD is preferred to surveillance, (6) endoscopic therapy for HGD is preferred to surgery, (7) the combination of endoscopic resection and radiofrequency ablation is the most effective therapy, and (8) after endoscopic removal of lesions from patients with HGD, all areas of BE should be ablated. CONCLUSIONS We developed a data-sifting platform and used the Delphi process to create evidence-based consensus statements for the management of patients with BE and early-stage EA. This approach identified important clinical features of the diseases and areas for future studies.

Abstract
Esophageal cancers have traditionally been diagnosed late and prognosis has been dire. For many years the only real treatment option was esophagectomy with substantial morbidity and mortality. This situation has now changed dramatically. Improvements have been achieved in surgical outcomes and there is an array of new effective treatment options now available, particularly for the increasing proportion diagnosed with early-stage disease. Minimally invasive endoscopic therapies can now prevent, cure or palliate esophageal cancers. This article aims to investigate the role and evidence base for these new therapeutic options.

Abstract
Laser thermal therapy represents a possible method to treat premalignant epithelial lesions of the esophagus. Dynamically conforming the thermal injury profile to a specific lesion boundary is expected to improve the efficacy of such a treatment and avoid complications. In this work, we investigated wavelength tuning as a mechanism to achieve this aimed control over injury depth by using the strong variation of water absorption close to 1900 nm. We developed a numerical model simulating in steps the photon propagation in the tissue, the diffusion of the absorbed heat, and the resulting tissue damage. The model was compared with experimental results on porcine esophageal specimens ex vivo and showed good agreement. Combined with power tuning, the wavelength agility in the range of 1860 to 1895 nm extends the injury range compared to a fixed wavelength source beyond 1 mm, while at the same time improving control over shallow depths and avoiding vaporization at the tissue surface. The combination of two or three discrete wavelengths combined at variable ratios provides similar control, and may provide an improved strategy for the treatment of endothelial lesions.

Abstract
Esophageal adenocarcinoma is the most rapidly increasing cancer in western countries. High-grade dysplasia (HGD) arising from Barrett’s esophagus (BE) is the most important risk factor for its development, and when it is present the reported incidence is up to 10% per patient-year. Adenocarcinoma in the setting of BE develops through a well known histological sequence, from non-dysplastic Barrett’s to low grade dysplasia and then HGD and cancer. Endoscopic surveillance programs have been established to detect the presence of neoplasia at a potentially curative stage. Newly developed endoscopic treatments have dramatically changed the therapeutic approach of BE. When neoplasia is confined to the mucosal layer the risk for developing lymph node metastasis is negligible and can be successfully eradicated by an endoscopic approach, offering a curative intention treatment with minimal invasiveness. Endoscopic therapies include resection techniques, also known as tissue-acquiring modalities, and ablation therapies or non-tissue acquiring modalities. The aim of endoscopic treatment is to eradicate the whole Barrett’s segment, since the risk of developing synchronous and metachronous lesions due to the persistence of molecular aberrations in the residual epithelium is well established.

Abstract
INTRODUCTION Esophageal cancer remains a challenging clinical problem, with overall long-term survivorship consistently at a level of approximately 30%. The incidence of esophageal cancer is increasing worldwide, with the most dramatic increase being seen with respect to esophageal adenocarcinoma. DISCUSSION Pretreatment staging accuracy has improved with the utilization of CT and PET scans, as well as endoscopic ultrasound and endoscopic mucosal resection. In an increasing percentage of patients, endoscopic techniques are being utilized in selected patients for the treatment of high-grade dysplasia in Barrett's and intramucosal cancer. Surgery remains the treatment of choice in all appropriate patients with invasive and locoregional esophageal cancer, although multimodality therapy is now used in most patients with stage II or stage III disease. CONCLUSION Outcomes for esophagectomy have been dominated by concerns regarding high mortality and morbidity; however, mortality rates associated with esophageal resection have dramatically decreased, especially in high-volume specialty centers. This manuscript highlights some of the evolutionary issues associated with staging and endoscopic and surgical treatments of Barrett's and esophageal cancer.
