Abstract
Background and Objective This narrative review discusses Barrett's esophagus management in the context of perceived deficiencies or controversies. Barrett's adenocarcinoma incidence has not clearly been impacted by Barrett's screening and surveillance. Methods The following report was derived from articles using PubMed and Google searches. The search was concentrated on Barrett's esophagus screening and management guidelines. Key Content and Findings Comprehensive literature searches that highlight potential deficiencies or controversies regarding the current approach to Barrett's esophagus were employed. Esophageal adenocarcinoma incidence is rapidly increasing and this malignancy usually presents in an advanced and unresectable state. This is despite the significant expenditure of resources and time in endoscopic screening for and surveillance of Barrett's esophagus. Thus, more widespread screening for Barrett's esophagus may be considered. In addition, there are apparent inefficiencies and precision lack in the performance of endoscopic surveillance. This relates mainly to the lack of endoscopic cues for dysplasia. On the other hand, relatively low-risk subjects have frequent screening or surveillance procedures increasing cost. Lastly, endoscopic ablation for Barrett's with dysplasia has moderately good efficacy, especially for eradication of dysplasia, but mandates intensive post-therapy endoscopic surveillance. There is some concern for subsurface development of advanced Barrett's lesions. Fortunately, there is intense research in improving Barrett's esophagus diagnosis and treatment. Our narrative review will delineate deficiencies and potential measures to remedy them. Conclusions In conclusion, screening for Barrett's esophagus and surveillance in Barrett's subjects have minimal established benefits, but proposed changes in screening practices and innovations in Barrett's esophagus endoscopic surveillance and dysplasia therapy have great promise.

Abstract
Barrett's esophagus is a precancerous condition that can progress in a stepwise manner to dysplasia and eventually esophageal adenocarcinoma (EAC). Once diagnosed, patients with Barrett's esophagus are kept on surveillance to detect progression so that timely intervention can occur with endoscopic therapy. Several demographic and clinical risk factors are known to increase progression toward EAC, such as longer Barrett's segments, and these patients are kept on tighter surveillance. While p53 IHC has been advocated as an adjunct to histopathologic diagnosis, use of this biomarker is variable, and no other molecular factors are currently applied. Given the new evidence available, it is time to consider whether other risk factors or tools could be applied in clinical practice to decide on closer or attenuated surveillance. In this commentary, we summarize the most relevant risk factors for Barrett's esophagus progression, highlight the most promising novel risk stratification tools-including nonendoscopic triage and commercial biomarker panels, and propose a new framework suggesting how to incorporate risk stratification into clinical practice.

Clinical variation in surveillance and management of Barrett's esophagus: A cross-sectional study of gastroenterologists and gastrointestinal surgeons. Medicine (Baltimore) 2022; 101:e32187.

Abstract
Appropriate surveillance and treatment of Barrett's esophagus (BE) is vital to prevent disease progression and decrease esophageal adenocarcinoma (EAC)-related mortality. We sought to determine the variation in BE care and identify improvement opportunities. 275 physicians (113 general gastroenterologists, 128 interventional gastroenterologists, 34 gastrointestinal surgeons) cared for 3 simulated patients, one each from 3 BE clinical scenarios: non-dysplastic BE (NDBE), BE indefinite for dysplasia (IND), and BE with low grade dysplasia (LGD), and care scores were measured against societal guidelines. Overall quality-of-care scores ranged from 17% to 85% with mean of 47.9% ± 11.8% for NDBE, 50.8% ± 11.7% for IND, and 52.7% ± 12.2% for LGD. Participants appropriately determined risk of progression 20.3% of the time: 14.4% for NDBE cases, 19.9% for LGD cases, and 26.8% for IND cases (P = .001). Treatment and follow-up care scores averaged 12.9% ± 17.5% overall. For the LGD cases, guideline-recommended twice-daily PPI treatment was ordered only 24.7% of the time. Guideline-based follow-up endoscopic surveillance was done in only 27.7% of NDBE cases and 32.7% of IND cases. For the LGD cases, 45.4% ordered endoscopic eradication therapy while 25.1% chose annual endoscopic surveillance. Finally, participants provided counseling on lifestyle modifications in just 20% of cases. Overall care of patients diagnosed with BE varied widely and showed room for improvement. Specific opportunities for improvement were adherence to guideline recommended surveillance intervals, patient counseling, and treatment selection for LGD. Physicians would potentially benefit from additional BE education, endoscopic advances, and better methods for risk stratification.

Prediction of Progression in Barrett's Esophagus Using a Tissue Systems Pathology Test: A Pooled Analysis of International Multicenter Studies. Clin Gastroenterol Hepatol 2022; 20:2772-2779.e8.

Abstract
BACKGROUND & AIMS Prediction of progression risk in Barrett's esophagus (BE) may enable personalized management. We aimed to assess the adjunct value of a tissue systems pathology test (TissueCypher) performed on paraffin-embedded biopsy tissue, when added to expert pathology review in predicting incident progression, pooling individual patient-level data from multiple international studies METHODS: Demographics, clinical features, the TissueCypher risk class/score, and progression status were analyzed. Conditional logistical regression analysis was used to develop multivariable models predicting incident progression with and without the TissueCypher risk class (low, intermediate, high). Concordance (c-) statistics were calculated and compared with likelihood ratio tests to assess predictive ability of models. A risk prediction calculator integrating clinical variables and TissueCypher risk class was also developed. RESULTS Data from 552 patients with baseline no (n = 472), indefinite (n = 32), or low-grade dysplasia (n = 48) (comprising 152 incident progressors and 400 non-progressors) were analyzed. A high-risk test class independently predicted increased risk of progression to high-grade dysplasia/adenocarcinoma (odds ratio, 6.0; 95% confidence interval, 2.9-12.0), along with expert confirmed low-grade dysplasia (odds ratio, 2.9; 95% confidence interval, 1.2-7.2). Model prediction of progression with the TissueCypher risk class incorporated was significantly superior than without, in the whole cohort (c-statistic 0.75 vs 0.68; P < .0001) and the nondysplastic BE subset (c-statistic 0.72 vs 0.63; P < .0001). Sensitivity and specificity of the high risk TissueCypher class were 38% and 94%, respectively. CONCLUSIONS An objective tissue systems pathology test high-risk class is a strong independent predictor of incident progression in patients with BE, substantially improving progression risk prediction over clinical variables alone. Although test specificity was high, sensitivity was modest.

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

Abstract
Barrett's esophagus is a widespread chronically progressing disease of heterogeneous nature. A life threatening complication of this condition is neoplastic transformation, which is often overlooked due to lack of standardized approaches in diagnosis, preventative measures and treatment. In this essay, we aim to stratify existing data to show specific associations between neoplastic transformation and the underlying processes which predate cancerous transition. We discuss pathomorphological, genetic, epigenetic, molecular and immunohistochemical methods related to neoplasia detection on the basis of Barrett's esophagus. Our review sheds light on pathways of such neoplastic progression in the distal esophagus, providing valuable insight into progression assessment, preventative targets and treatment modalities. Our results suggest that molecular, genetic and epigenetic alterations in the esophagus arise earlier than cancerous transformation, meaning the discussed targets can help form preventative strategies in at-risk patient groups.
