[PMID: 40381316 PMCID: PMC12085195 DOI: 10.1093/dote/doaf038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2024] [Revised: 03/30/2025] [Accepted: 04/30/2025] [Indexed: 05/20/2025]
Abstract
Barrett's esophagus is the precursor to esophageal adenocarcinoma. Esophageal adenocarcinoma detected from endoscopic surveillance programs accounts for <10% of all cases, suggesting majority of patients with Barrett's esophagus are likely unaccounted for. Previous observational studies have estimated the observed prevalence of Barrett's esophagus to be approximately 1%, but others suggest may be an underestimate. The aim of this study was twofold: (i) calculate lifetime risk of esophageal adenocarcinoma and (ii) estimate overall and age-specific prevalence of Barrett's esophagus. A tree cohort model was created for progression to esophageal adenocarcinoma from birth to death (100 years) for USA and Australian population. Lifetime risk of esophageal cancer and adenocarcinoma were necessary for calculating Barrett's esophagus prevalence. The model incorporated age- and sex-specific incidence data from national cancer registries: the Australian Institute of Health and Welfare and the Surveillance, Epidemiology, and End Results database for the USA. The model was calibrated using an optimization algorithm, which matched progression rates from Barrett's esophagus to esophageal adenocarcinoma with known national cancer data. A Monte Carlo simulation, with 10,000 iterations, was conducted to derive error margins. Estimates of age-specific and overall prevalence of Barrett's esophagus in the population were generated through a similar process. Results: The lifetime risk of esophageal cancer and adenocarcinoma in USA non-Hispanic White population was 0.56% and 0.36%, respectively, while it was somewhat higher at 0.81% and 0.61% (range 0.57%-0.65%) in the Australian population. Estimated overall prevalence of Barrett's esophagus was ~3% (±0.3%) and ~ 5.4% (±0.6%) in USA White and Australian populations (male and female). Prevalence for age brackets was estimated at 0.06% (±0.02%), 1.6% (±0.7%), 3.2% (±1.3%), 8% (±3%), and 12% (±4%) for USA, and 0.05% (±0.02%), 0.9% (±0.5%), 2.8% (±1.2%), 7% (±3%), and 12% (±4%) for Australian population for ages 0-29, 30-44, 45-59, 60-74, and 75+, respectively. Observed estimates of Barrett's esophagus prevalence are likely lower than projected overall prevalence. This study also presents age-specific prevalence estimates of Barrett's esophagus, which are key in developing screening programs for esophageal adenocarcinoma.

Abstract
INTRODUCTION Current guidelines recommend endoscopic surveillance of Barrett's esophagus (BE) but do not account for competing mortality unrelated to esophageal cancer (EC). We conducted a systematic review and meta-analysis to estimate EC and non-EC mortality risk in BE patients. METHODS We searched multiple databases for studies reporting mortality in BE. We included population-based studies providing standardized mortality ratio (SMR). The primary outcome was SMR from all causes and EC and non-EC etiologies. SMR was calculated by dividing the observed mortality over the expected mortality. Logarithmic form of SMRs was pooled using random-effects model. RESULTS Our search yielded 2,826 articles, of which 7 studies (n = 34,454) were included. All-cause mortality was elevated in BE patients compared with population controls (pooled SMR 1.24, 95% confident interval [CI] 1.01-1.53) driven in part by increased EC mortality risk (SMR 8.98, 95 CI 5.12-15.77). The mortality risk was still increased but attenuated after excluding EC mortality (SMR 1.21, 95% CI 1-1.46). There was no increased mortality risk of non-EC malignancies (SMR 1.22, 95% CI 0.82-1.82) or mortality due to noncancer etiologies (SMR 1.13, 95% CI 0.90-1.43). Death due to cardiovascular diseases was higher in BE (SMR 1.16, 95% CI 1.02-1.33). BE patients were 10 times more likely to die from noncancer etiologies than EC (risk ratio 10.71, 95% CI 5.98-19.16). Subgroup analysis of studies that excluded prevalent EC at baseline (3 studies) also showed increased all-cause (SMR 1.12, 95% CI 1.07-1.18) and EC mortality (SMR 4.7, 95% CI 3.58-6.17) among BE patients. DISCUSSION BE patients exhibit a higher all-cause mortality, driven in part by risk of EC mortality. A personalized approach to surveillance, mitigating risk of EC while recognizing the broader mortality risks, is warranted.

Incidence and Prediction of Unrelated Mortality After Successful Endoscopic Eradication Therapy for Barrett's Neoplasia. Gastroenterology 2024; 166:1058-1068.

Abstract
BACKGROUND & AIMS Follow-up (FU) strategies after endoscopic eradication therapy (EET) for Barrett's neoplasia do not consider the risk of mortality from causes other than esophageal adenocarcinoma (EAC). We aimed to evaluate this risk during long-term FU, and to assess whether the Charlson Comorbidity Index (CCI) can predict mortality. METHODS We included all patients with successful EET from the nationwide Barrett registry in the Netherlands. Data were merged with National Statistics for accurate mortality data. We evaluated annual mortality rates (AMRs, per 1000 person-years) and standardized mortality ratio for other-cause mortality. Performance of the CCI was evaluated by discrimination and calibration. RESULTS We included 1154 patients with a mean age of 64 years (±9). During median 59 months (p25-p75 37-91; total 6375 person-years), 154 patients (13%) died from other causes than EAC (AMR, 24.1; 95% CI, 20.5-28.2), most commonly non-EAC cancers (n = 58), cardiovascular (n = 31), or pulmonary diseases (n = 26). Four patients died from recurrent EAC (AMR, 0.5; 95% CI, 0.1-1.4). Compared with the general Dutch population, mortality was significantly increased for patients in the lowest 3 age quartiles (ie, age <71 years). Validation of CCI in our population showed good discrimination (Concordance statistic, 0.78; 95% CI, 0.72-0.84) and fair calibration. CONCLUSION The other-cause mortality risk after successful EET was more than 40 times higher (48; 95% CI, 15-99) than the risk of EAC-related mortality. Our findings reveal that younger post-EET patients exhibit a significantly reduced life expectancy when compared with the general population. Furthermore, they emphasize the strong predictive ability of CCI for long-term mortality after EET. This straightforward scoring system can inform decisions regarding personalized FU, including appropriate cessation timing. (NL7039).

Abstract
Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Progression to cancer typically occurs in a stepwise fashion through worsening dysplasia and ultimately, invasive neoplasia. Established EAC with deep involvement of the esophageal wall and/or metastatic disease is invariably associated with poor long-term survival rates. This guides the rationale of surveillance of Barrett’s in an attempt to treat lesions at an earlier, and potentially curative stage. The last two decades have seen a paradigm shift in management of Barrett’s with rapid expansion in the role of endoscopic eradication therapy (EET) for management of dysplastic and early neoplastic BE, and there have been substantial changes to international consensus guidelines for management of early BE based on evolving evidence. This review aims to assist the physician in the therapeutic decision-making process with patients by comprehensive review and summary of literature surrounding natural history of Barrett’s by histological stage, and the effectiveness of interventions in attenuating the risk posed by its natural history. Key findings were as follows. Non-dysplastic Barrett’s is associated with extremely low risk of progression, and interventions cannot be justified. The annual risk of cancer progression in low grade dysplasia is between 1%-3%; EET can be offered though evidence for its benefit remains confined to highly select settings. High-grade dysplasia progresses to cancer in 5%-10% per year; EET is similarly effective to and less morbid than surgery and should be routinely performed for this indication. Risk of nodal metastases in intramucosal cancer is 2%-4%, which is comparable to operative mortality rate, so EET is usually preferred. Submucosal cancer is associated with nodal metastases in 14%-41% hence surgery remains standard of care, except for select situations.

Abstract
Aim The aim of this study was to investigate the incidence of dysplastic transformation of Barrett's esophagus (BE) in a Chinese population. Method Data from nondysplastic BE patients at Taichung Veterans General Hospital were collected from May 2008 to June 2017. The enrolled individuals received regular upper gastrointestinal (UGI) endoscopy during follow up. The pathological transformations, including low-grade dysplasia (LGD), high-grade dysplasia (HGD), or esophageal adenocarcinoma (EAC), were collected prospectively until June 2017. Rates of progression were calculated in cases with a diagnosis of dysplasia or EAC. Results There were 51 subjects who met the inclusion criteria, with a mean follow up of 3.71 years (SD, 1.61) and a total follow up of 189.1 patient-years. Eight cases (15.7%) developed LGD, with a calculated incidence rate of 2.9% per year. The mean time to development of LGD was 3.26 years (SD, 2.68-3.84). One subject (2%) developed EAC, with a calculated incidence rate of 0.4% per year. No case with HGD was detected. Conclusion In a Chinese population with nondysplastic BE, 15.7% of cases developed LGD, with an incidence rate of 2.9% per year, and 2% of cases developed EAC, with an incidence rate of 0.4% per year.

Abstract
Centrosome abnormalities are a typical hallmark of human cancers. However, the origin and dynamics of such abnormalities in human cancer are not known. In this study, we examined centrosomes in Barrett's esophagus tumorigenesis, a well-characterized multistep pathway of progression, from the premalignant condition to the metastatic disease. This human cancer model allows the study of sequential steps of progression within the same patient and has representative cell lines from all stages of disease. Remarkably, centrosome amplification was detected as early as the premalignant condition and was significantly expanded in dysplasia. It was then present throughout malignant transformation both in adenocarcinoma and metastasis. The early expansion of centrosome amplification correlated with and was dependent on loss of function of the tumor suppressor p53 both through loss of wild-type expression and hotspot mutations. Our work shows that centrosome amplification in human tumorigenesis can occur before transformation, being repressed by p53. These findings suggest centrosome amplification in humans can contribute to tumor initiation and progression.

Abstract
BACKGROUND & AIMS Endoscopic surveillance of patients with Barrett's esophagus (BE) is inefficient. Risk stratification of patients might improve the effectiveness of surveillance. We performed a systematic review and meta-analysis to identify factors associated with progression of BE without dysplasia or BE with low-grade dysplasia (LGD) to high-grade dysplasia or esophageal adenocarcinoma. METHODS We performed a systematic search of databases through May 2016 to identify cohort studies of patients with baseline BE without dysplasia or BE with LGD that reported predictors of progression. Pooled estimates (odds ratios) of associations of age, sex, smoking, alcohol use, obesity, baseline LGD, segment length, and medication use with progression were calculated. RESULTS We identified 20 studies, reporting 1231 events in 74943 patients. The studies associated BE progression with increasing age (12 studies; odds ratio [OR], 1.03; 95% CI, 1.01-1.05), male sex (11 studies; OR, 2.16; 95% CI, 1.84-2.53), ever smoking (current or past, 8 studies; OR, 1.47; 95% CI, 1.09-1.98), and increasing BE segment length (10 studies; OR, 1.25; 95% CI, 1.16-1.36), with a low degree of heterogeneity. LGD was associated with a 4-fold increase in risk of BE progression (11 studies; OR, 4.25; 95% CI, 2.58-7.0). Use of proton pump inhibitors (4 studies; OR, 0.55; 95% CI, 0.32-0.96) or statins (3 studies; OR, 0.48; 95% CI, 0.31-0.73) were associated with lower risk of BE progression. Alcohol use and obesity did not associate with risk of progression. CONCLUSIONS In a systematic review and meta-analysis, we associated older age, male sex, smoking, longer BE segment, and LGD with risk of progression of BE. Individuals with these features should undergo more intensive surveillance or endoscopic therapy. Smoking is a modifiable risk factor for cancer prevention in patients with BE.

[PMID: 28053055 PMCID: PMC5827961 DOI: 10.1136/gutjnl-2016-312223] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 12/01/2016] [Accepted: 12/04/2016] [Indexed: 12/15/2022]
Abstract
OBJECTIVE Barrett's oesophagus (BE) increases the risk of oesophageal adenocarcinoma by 10-55 times that of the general population, but no community-based cancer-specific incidence and cause-specific mortality risk estimates exist for large cohorts in the USA. DESIGN Within Kaiser Permanente Northern California (KPNC), we identified patients with BE diagnosed during 1995-2012. KPNC cancer registry and mortality files were used to estimate standardised incidence ratios (SIR), standardised mortality ratios (SMR) and excess absolute risks. RESULTS There were 8929 patients with BE providing 50 147 person-years of follow-up. Compared with the greater KPNC population, patients with BE had increased risks of any cancer (SIR=1.40, 95% CI 1.31 to 1.49), which slightly decreased after excluding oesophageal cancer. Oesophageal adenocarcinoma risk was increased 24 times, which translated into an excess absolute risk of 24 cases per 10 000 person-years. Although oesophageal adenocarcinoma risk decreased with time since BE diagnosis, oesophageal cancer mortality did not, indicating that the true risk is stable and persistent with time. Relative risks of cardia and stomach cancers were increased, but excess absolute risks were modest. Risks of colorectal, lung and prostate cancers were unaltered. All-cause mortality was slightly increased after excluding oesophageal cancer (SMR=1.24, 95% CI 1.18 to 1.31), but time-stratified analyses indicated that this was likely attributable to diagnostic bias. Cause-specific SMRs were elevated for ischaemic heart disease (SMR=1.39, 95% CI 1.18 to 1.63), respiratory system diseases (SMR=1.51, 95% CI 1.29 to 1.75) and digestive system diseases (SMR=2.20 95% CI 1.75 to 2.75). CONCLUSIONS Patients with BE had a persistent excess risk of oesophageal adenocarcinoma over time, although their absolute excess risks for this cancer, any cancer and overall mortality were modest.

Mortality and cardiovascular diseases risk in patients with Barrett's oesophagus: a population-based nationwide cohort study. Aliment Pharmacol Ther 2017; 45:973-982. [PMID: 28139003 DOI: 10.1111/apt.13962] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Revised: 01/10/2017] [Accepted: 01/10/2017] [Indexed: 12/18/2022]
Abstract
BACKGROUND Patients with Barrett's oesophagus may be at increased risk of mortality overall, and cardiovascular disease has been suggested as the main underlying cause of death. AIM To examine cause-specific mortality and risk of cardiovascular events among patients with Barrett's oesophagus. METHODS Utilising existing Danish data sources (1997-2011), we identified all patients with histologically verified Barrett's oesophagus (n = 13 435) and 123 526 members of the general population matched by age, sex and individual comorbidities. We calculated cause-specific mortality rates and incidence rates of cardiovascular diseases. We then compared rates between patients with Barrett's oesophagus and the general population comparison cohort, using stratified Cox proportional hazard regression. RESULTS Patients with Barrett's oesophagus had a 71% increased risk of overall mortality. The cause-specific mortality rate per 1000 person-years for patients with Barrett's oesophagus was 8.5 for cardiovascular diseases, 14.7 for non-oesophageal cancers, and 5.4 for oesophageal cancer. Compared to the general population cohort, corresponding hazard ratios were 1.26 (95% confidence interval (CI): 1.15-1.38), 1.77 (95% CI: 1.65-1.90), and 19.4 (95% CI: 16.1-23.4), respectively. The incidence rates of cardiovascular diseases per 1000 person-years for Barrett's oesophagus patients and for persons from the general population cohort, respectively, varied from 0.4 and 0.2 for subarachnoid bleeding (hazard ratio 1.10, 95% CI: 0.87-1.39) to 8.1 and 5.9 for congestive heart failure (hazard ratio 1.33, 95% CI: 1.21-1.46). CONCLUSION Prophylactic measures targeted at cardiovascular diseases and non-oesophageal cancers potentially could be more important than measures against oesophageal cancer, for improving prognosis among patients with Barrett's oesophagus.

Systematic review with meta-analysis: prevalent vs. incident oesophageal adenocarcinoma and high-grade dysplasia in Barrett's oesophagus. Aliment Pharmacol Ther 2016; 44:775-84. [PMID: 27562355 DOI: 10.1111/apt.13783] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2016] [Revised: 07/20/2016] [Accepted: 08/05/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND The proportion of oesophageal adenocarcinoma that is detected concurrently with initial Barrett's oesophagus diagnosis is not well studied. AIM To compare the proportion of prevalent adenocarcinoma vs. incident adenocarcinoma found during surveillance of Barrett's. METHODS We performed a systematic search of MEDLINE, EMBASE and Web of Science (from their inception to 31 May 2015) for cohort studies in adults with Barrett's (nondysplastic Barrett's ± Barrett's with low-grade dysplasia) with minimum average follow-up of 3 years, and providing numbers of prevalent adenocarcinoma detected (concurrently with Barrett's diagnosis and up to 1 year afterwards) vs. incident adenocarcinoma detected (greater than 1 year after Barrett's diagnosis). Pooled weighted proportions of prevalent and incident adenocarcinoma were calculated, using a random effects model. RESULTS On meta-analysis of 13 studies reporting on 603 adenocarcinomas in 9657 Barrett's patients, 85.1% of adenocarcinomas were classified as prevalent [95% confidence interval (CI), 78.1-90.2%) and 14.9% as incident (95% CI, 9.8-21.9%), with substantial heterogeneity (I(2) = 66%). Among nine studies reporting on 787 high-grade dysplasia and oesophageal adenocarcinomas in 8098 Barrett's patients, the proportion of prevalent high-grade dysplasia-oesophageal adenocarcinoma was similar at 80.5% (95% CI, 68.1-88.8%, I(2) = 87%). These results remained stable across multiple subgroup analyses including study quality, setting, duration of follow-up and presence of baseline dysplasia. CONCLUSIONS In our meta-analysis, four of five patients diagnosed with adenocarcinoma or high-grade dysplasia at index endoscopy or within 1 year of Barrett's follow-up were considered to be prevalent cases. Continued efforts are needed to identify patients with Barrett's before the development of adenocarcinoma.

Abstract
BACKGROUND Narrow band imaging (NBI) is used in the detection of intestinal metaplasia (IM) and dysplasia in patients with Barrett's oesophagus (BE). AIMS The study compared the usefulness of NBI with white-light standard endoscopy (WLSE) for the detection of dysplasia and IM in BE and determined the prediction of the histological diagnosis according to the mucosal and vascular patterns obtained by NBI. PATIENTS AND METHODS A total of 84 patients were prospectively enrolled in the study. Every patient underwent a WLSE with random biopsies and after 4-6 weeks, a NBI examination was performed. RESULTS NBI detected significant more IM positive biopsies than WLSE (74.5% vs. 35.9%; p<0.0001) and significant more patients with low grade dysplasia (LGD) (7.1% vs. 0%; p=0.03). Taking biopsy samples from the villous pattern determined the diagnosis of IM (80%) and biopsies from the area covered by the irregular pattern lead to the identification of LGD in 45.4% of the cases and indefinite dysplasia (ID) in 18.2% of the cases. CONCLUSION A thorough analysis of NBI patterns may lead to real-time IM diagnosis in the absence of the histological examination and may require targeted biopsies from the areas with an irregular pattern for diagnosing dysplasia.

Abstract
BACKGROUND Varying rates of oesophageal adenocarcinoma (OAC) complicating Barrett's oesophagus (BO) have been reported. Recent studies and meta-analyses suggest a lower incidence, questioning the value of endoscopic surveillance. AIM We aimed to retrospectively examine the rate of OAC, risk factors and causes of death in a prospectively recruited BO cohort. METHODS Data from patients with BO from a cohort from 1982-2007 were studied. Patients were subdivided into surveyed, failed to attend surveillance and unfit for surveillance. Standardised mortality ratios (SMR) were calculated for common causes of death. Cox proportional hazards models were used to determine which factors were associated with progression to OAC. RESULTS In total, 671 BO patients (61% male) were studied; 37 (76% male) were diagnosed with OAC. OAC incidence was 0.47% per annum and stable across three decades (1982-1991 0.56%, 1992-2001 0.46%, 2002-2012 0.41% (p = 0.8)). All-cause mortality was increased for the whole cohort (SMR 163(95% CI 145-183)). Mortality from OAC appeared higher in patients who failed to attend surveillance (SMR 3216(95% CI 1543-5916)) compared with surveyed (SMR 1753(95% CI 933-2998)) and those unfit for surveillance due to co-morbidity (SMR 440(95% CI 143-1025)). Multivariable analysis identified low-grade dysplasia (HR 4.4(95% CI 1.56-12.43), p = 0.005) and length of BO (HR 1.2(95% (1.1-1.3)), p < 0.001)) as associated with OAC. CONCLUSIONS Progression to OAC appeared stable over three decades at 0.47% per annum. Patients with BO had a modest increase in all-cause mortality and a large increase in OAC mortality, particularly if fit for surveillance. Low-grade dysplasia and the length of the BO segment were associated with developing OAC.

Abstract
BACKGROUND & AIMS Radiofrequency ablation (RFA) is commonly used to treat Barrett's esophagus (BE). We assessed the incidence of esophageal adenocarcinoma (EAC) after RFA, factors associated with the development of EAC, and EAC-specific and all-cause mortality. METHODS We collected data for outcomes of patients who underwent RFA for BE from July 2007 through July 2011 from US multicenter RFA Patient Registry. Patients were followed until July 2014. Kaplan-Meier curves of EAC incidence were stratified by baseline histology. Crude EAC incidence and mortality (all-cause and EAC-specific) were calculated, and adjusted all-cause mortality was assessed. Logistic regression models were constructed to assess predictors of EAC and all-cause mortality. RESULTS Among 4982 patients, 100 (2%) developed EAC (7.8/1000 person-years [PY]) and 9 patients (0.2%) died of EAC (0.7/1000 PY) in a mean 2.7 ± 1.6 years. The incidence of EAC in nondysplastic BE was 0.5/1000 PY. Overall, 157 patients (3%) died during follow-up (all-cause mortality, 11.2/1000 PY). On multivariate logistic regression, baseline BE length (odds ratio, 1.1/ cm) and baseline histology (odds ratios, 5.8 and 50.3 for low-grade dysplasia and high-grade dysplasia [HGD] respectively) predicted EAC incidence. Among 9 EAC deaths, 6 (67%) had baseline HGD, and 3 (33%) had baseline intramucosal EAC. The most common causes of death were cardiovascular (15%) and extraesophageal cancers (15%). No deaths were associated with RFA. CONCLUSIONS Based on analysis of a multicenter registry of patients who underwent RFA of BE, less than 1% died from EAC. The incidence of EAC was markedly lower in this study than in other studies of disease progression, with the greatest absolute benefit observed in patients with HGD.

Abstract
BACKGROUND The risk of esophageal adenocarcinoma (EAC) in non-dysplastic Barrett's esophagus (NDBE) is considered to be approximately 0.3% per year or even lower, according to population-based studies. Data from countries with low EAC incidence are scarce. Our principal aim was to determine the incidence of high-grade dysplasia (HGD) and EAC in NDBE. Our secondary aims were to identify the predictors of progression and to calculate the incidence of HGD/EAC, by using the calculation method for surveillance time in population-based studies. MATERIALS AND METHODS A cohort of NDBE patients was prospectively followed up. Cases of HGD and EAC (study end points) diagnosed during the first year of follow-up were considered as prevalent. Only cases with an endoscopic surveillance time > 1 year were included in our analysis. RESULTS We enrolled 331 patients (251 men) in the surveillance program. Their median age was 59 years (interquartile range (IQR): 47-67 years). Their median NDBE length was 3 cm (IQR: 2-4 cm). Of these patients, 80 died during the follow-up (one from EAC) and two were lost to follow-up. After 2284 patient-years of endoscopic follow-up (median surveillance time, 5 years (IQR: 2-10 years)), we found that five cases of HGD and two cases of EAC were diagnosed. The incidence of HGD/EAC was 3.1 cases per 1000 patient-years (95% CI: 1.3-6.0) and that of EAC was 0.9 (95% CI: 0.2-2.9). The incidence of HGD/EAC in short segments (≤ 3 cm) was 0.7 cases per 1000 patient-years (95% CI: 0.3-3.4). The sole variable that we found associated with progression was NDBE length. If the total surveillance time was considered (3537 patient-years), the incidence of HGD and EAC was only slight lower. CONCLUSIONS The incidence of HGD and EAC was very low in NDBE. Therefore, current surveillance guidelines must be reassessed, at least for short-segment BE.

Abstract
Barrett's esophagus is a known precursor for esophageal adenocarcinoma. Early detection of dysplasia provides a window of opportunity for curative intervention. Several image-enhanced technologies have been developed to improve visualization of neoplasia. These however have not been found to be superior to the standard four quadrant random biopsy protocol. Patients are risk-stratified based on the degree of dysplasia found on biopsies and undergo either surveillance or treatment. Endoscopic therapy has become the mainstay of treatment for early neoplasia.

Abstract
Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC), a disease with increasing burden in the Western world, especially in white men. Risk factors for BE include obesity, tobacco smoking, and gastroesophageal reflux disease (GERD). EAC is the most common form of esophageal cancer in the United States. Risk factors include GERD, tobacco smoking, and obesity, whereas nonsteroidal antiinflammatory drugs and statins may be protective. Factors predicting progression from nondysplastic BE to EAC include dysplastic changes on esophageal histology and length of the involved BE segment. Biomarkers have shown promise, but none are approved for clinical use.

Abstract
Barrett's esophagus (BE), a common condition, is the only known precursor to esophageal adenocarcinoma (EAC). There is uncertainty about the best way to manage BE as most people with BE never develop EAC and most patients diagnosed with EAC have no preceding diagnosis of BE. Moreover, there have been recent advances in knowledge and practice about the management of BE and early EAC. To aid clinical decision making in this rapidly moving field, Cancer Council Australia convened an expert working party to identify pertinent clinical questions. The questions covered a wide range of topics including endoscopic and histological definitions of BE and early EAC; prevalence, incidence, natural history, and risk factors for BE; and methods for managing BE and early EAC. The latter considered modification of lifestyle factors; screening and surveillance strategies; and medical, endoscopic, and surgical interventions. To answer each question, the working party systematically reviewed the literature and developed a set of recommendations through consensus. Evidence underpinning each recommendation was rated according to quality and applicability.

Abstract
The incidence of oesophageal adenocarcinoma is continuing to increase at an alarming rate in the Western world today. Barrett's oesophagus is a clearly recognized risk factor for the development of oesophageal adenocarcinoma, but the overwhelming majority of patients with Barrett's oesophagus will never develop oesophageal cancer. A number of endoscopic, histologic and epidemiologic risk factors identify Barrett's oesophagus patients at increased risk for progression to high-grade dysplasia and oesophageal adenocarcinoma. Endoscopic factors include segment length, mucosal abnormalities as seemingly trivial as oesophagitis and the 12 to 6 o'clock hemisphere of the oesophagus. Both intestinal metaplasia and low grade dysplasia, the latter only if confirmed by a pathologist with expertise in Barrett's oesophagus pathologic interpretation are the histologic risk factors for progression. Epidemiologic risk factors include ageing, male gender, obesity, and smoking. Factors that may protect against the development of adenocarcinoma include a diet rich in fruits and vegetables, and the use of proton pump inhibitors, aspirin/NSAIDs and statins.

Abstract
Barrett’s esophagus (BE) develops as a consequence of chronic esophageal acid exposure, and is the major risk factor for esophageal adenocarcinoma (EAC). The practices of endoscopic screening for—and surveillance of—BE, while widespread, have failed to reduce the incidence of EAC. The majority of EACs are diagnosed in patients without a known history of BE, and current diagnostic tools are lacking in their ability to stratify patients with BE into those at low risk and those at high risk for progression to malignancy. Nonetheless, advances in endoscopic imaging and mucosal therapeutics have provided unprecedented opportunities for intervention for BE, and have vastly altered the approach to management of BE-associated mucosal neoplasia.

Abstract
Barrett oesophagus is an important precursor lesion for the development of oesophageal adenocarcinoma (OAC). Upper gastrointestinal endoscopy is the modality most widely used to visualize and biopsy the oesophagus to establish a diagnosis. Additional clues are available at the time of endoscopy that can identify high-risk features known to increase the risk of progression to OAC, such as the length of the Barrett oesophagus segment, length of hiatal hernia and the presence of nodularity or visible endoscopic lesions in this segment. Until molecular biomarkers are identified and validated as adjunctive tools for risk stratification, knowledge of endoscopic features could complement dysplasia grading for risk stratification of patients with Barrett oesophagus and identify subgroups at risk of progression to OAC. This approach would, in turn, facilitate more rational tailoring of endoscopic surveillance. This Review summarizes the current role of endoscopic and histological factors involved in neoplastic progression of Barrett oesophagus to OAC, and provides an overview of the risk-prediction models that have utilized endoscopic and histological factors for risk stratification in patients with Barrett oesophagus.

Abstract
BACKGROUND The natural history of low-grade dysplasia (LGD) in patients with Barrett's esophagus (BE) is unclear. OBJECTIVE We performed a systematic review and meta-analysis of studies that reported the incidence of esophageal adenocarcinoma (EAC) and/or high-grade dysplasia (HGD) among patients with BE with LGD. DESIGN Systematic review and meta-analysis of cohort studies. PATIENTS Patients with BE-LGD, with mean cohort follow-up ≥ 2 years. MAIN OUTCOME MEASUREMENTS Pooled incidence rates with 95% confidence intervals (CI) of EAC and/or BE-HGD. RESULTS We identified 24 studies reporting on 2694 patients with BE-LGD, with 119 cases of EAC. Pooled annual incidence rates of EAC alone and EAC and/or HGD in patients with BE-LGD were 0.54% (95% CI, 0.32-0.76; 24 studies) and 1.73% (95% CI, 0.99-2.47; 17 studies). The results were stable across study setting and location and in high-quality studies. Substantial heterogeneity was observed, which could be explained by stratifying based on LGD/BE ratio as a surrogate for quality of pathology; the pooled annual incidence rates of EAC were 0.76% (95% CI, 0.44-1.09; 14 studies) for LGD/BE ratio <0.15 and 0.32% (95% CI, 0.07-0.58; 10 studies) for LGD/BE ratio >0.15. The annual rate of mortality not related to esophageal disease in patients with BE-LGD was 4.7% (95% CI, 3.2-6.2; 4 studies). LIMITATIONS Substantial heterogeneity was observed in the overall analysis. CONCLUSION The incidence of EAC among patients with BE-LGD is 0.54% annually. The LGD/BE ratio appears to explain the variation observed in the reported incidence of EAC in different cohorts. Conditions not related to esophageal disease are a major cause of mortality in patients with BE-LGD, although additional studies are warranted.

Abstract
BACKGROUND The published prevalence of Barrett's esophagus (BE) varies from 0.9% to 25%, in part because of differences in the endoscopic interpretation of the disease. OBJECTIVE We studied the accuracy of diagnosis in 130 patients previously labeled as having BE. Our aim was to determine the interobserver consistency of endoscopic findings and assess the percentage of patients with confirmed BE versus those with a revised diagnosis. DESIGN/SETTING/PATIENTS Patients previously diagnosed with BE of any length and due for surveillance endoscopy were eligible for study. INTERVENTIONS After intensive consensus anatomic and endoscopic review, study patients underwent endoscopy and biopsy by 1 of 3 endoscopists. BE was defined as any length of columnar-lined esophagus with goblet cells. MAIN OUTCOME MEASUREMENTS Patients were photographed/videotaped for review by the other 2 endoscopists, and BE was either confirmed or revised. RESULTS Eighty-eight patients (67.7%) had confirmed BE, and 42 (32.3%) had their diagnosis revised to no BE (95% confidence interval, 24.4%-41.1%) because there was no visible columnar-lined esophagus proximal to the gastric folds or no goblet cells were found on biopsy. BE length, site of previous endoscopy, age, sex, and hiatal hernia size were predictors of revision. All 3 endoscopists agreed on all confirmed BE cases and 38 of 42 of those revised. LIMITATIONS Retrospective analysis, possible sampling error. CONCLUSIONS BE is overdiagnosed in clinical practice with important implications for patient care including increased costs, reduced insurability, and psychological stress. The true BE cancer risk may also be underestimated. This study suggests the need for a better definition of the gastroesophageal junction, stricter accountability for BE diagnosis, and improved endoscopic education.

Abstract
Although endoscopic surveillance of patients with Barrett's oesophagus has been widely implemented, its effectiveness is debateable. The recently reported low annual oesophageal adenocarcinoma risk in population studies, the failure to identify most Barrett's patients at risk of disease progression, the poor adherence to surveillance and biopsy protocols, and the significant risk of misclassification of dysplasia all tend to undermine the effectiveness of current management, in particular, endoscopic surveillance programmes, to prevent or improve the outcomes of patients with oesophageal adenocarcinoma. The ongoing increase in incidence of Barrett's oesophagus and consequent growth of the surveillance population, together with the associated discomfort and costs of endoscopic surveillance, demand improved techniques for accurately determining individual risk of oesophageal adenocarcinoma. More accurate techniques are needed to run efficient surveillance programmes in the coming decades. In this review, we will discuss the current knowledge on the epidemiology of Barrett's oesophagus, and the challenging epidemiological dilemmas that need to be addressed when assessing the current screening and surveillance strategies.

Abstract
BACKGROUND & AIMS It is not clear whether length of Barrett's esophagus (BE) is a risk factor for high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) in patients with nondysplastic BE. We studied the risk of progression to HGD or EAC in patients with nondysplastic BE, based on segment length. METHODS We analyzed data from a large cohort of patients participating in the BE Study-a multicenter outcomes project comprising 5 US tertiary care referral centers. Histologic changes were graded as low-grade dysplasia, HGD, or EAC. The study included patients with BE of documented length without dysplasia and at least 1 year of follow-up evaluation (n = 1175; 88% male), and excluded patients who developed HGD or EAC within 1 year of their BE diagnosis. The mean follow-up period was 5.5 y (6463 patient-years). The annual risk of HGD and EAC was plotted in 3-cm increments (≤3 cm, 4-6 cm, 7-9 cm, 10-12 cm, and ≥13 cm). We calculated the association between time to progression and length of BE. RESULTS The mean BE length was 3.6 cm; 44 patients developed HGD or EAC, with an annual incidence rate of 0.67%/y. Compared with nonprogressors, patients who developed HGD or EAC had longer BE segments (6.1 vs 3.5 cm; P < .001). Logistic regression analysis showed a 28% increase in risk of HGD or EAC for every 1-cm increase in BE length (P = .01). Patients with BE segment lengths of 3 cm or shorter took longer to develop HGD or EAC than those with lengths longer than 4 cm (6 vs 4 y; P = nonsignificant). CONCLUSIONS In patients with BE without dysplasia, length of BE was associated with progression to HGD or EAC. The results support the development of a risk stratification scheme for these patients based on length of BE segment.

Abstract
BACKGROUND Barrett's high grade dysplasia (HGD) is a pre-malignant condition which requires treatment with either oesophagectomy or ablative endoscopic therapy. Endoscopic ablative techniques have evolved through Photodynamic Therapy (PDT) to more recently radiofrequency ablation (RFA). Although RFA has superseded PDT due to improved efficacy and safety profile there remains a significant cohort of patients previously treated by PDT where the long term outcome is unclear. This study's aim was to assess the long term efficacy of PDT in patients with Barrett's HGD. METHODS Between June 2002 and 2007 21 patients (16 male, median age 70) underwent PDT for HGD in Barrett's oesophagus. Patients received intravenous photosensitiser Photofrin (Porfimer sodium) forty eight hours prior to endoscopic light activation by laser light at 630 nm. The patients returned at 6-12 weekly intervals for repeat endoscopy and biopsy. RESULTS Sixteen patients remained free of HGD at median 62 (range 36-114) months. Three patients developed adenocarcinoma at 47, 48 and 54 months (15%). Two patients were treated endoscopically with RFA and YAG laser, while one patient had surgical resection. Four patients developed recurrent HGD treated with repeat PDT. There was a significant reduction in length of Barrett's segment (from 5 cm to 3 cm) post PDT. The stricture rate requiring endoscopic therapy was 37% and 10% of patients developed photosensitivity reactions. CONCLUSION PDT successfully ablated HGD in 84% of patients and could therefore still be considered an effective salvage treatment for this condition in patients with co-morbidities precluding them for surgical resection.

Abstract
Surgical pathologists need to answer 2 questions when evaluating biopsies from the distal esophagus or gastroesophageal junction in patients with a history of gastroesophageal reflux disease: Are the findings consistent with Barrett esophagus? and Is there any evidence of dysplasia? Pathologists should be well informed about the controversy around the definition of Barrett esophagus and the common pitfalls that lead to a false-positive diagnosis of Barrett esophagus or Barrett esophagus-associated dysplasia. A concise description of distinct morphologic types of dysplasia in Barrett esophagus and a summary of recent data on the natural history of BE are provided in this review.

Abstract
Oesophageal adenocarcinoma will soon cease to be a rare form of cancer for people born after 1940. In many Western countries, its incidence has increased more rapidly than other digestive cancers. Incidence started increasing in the Seventies in England and USA, 15 years later in Western Europe and Australia. The cumulative risk between the ages of 15 and 74 is particularly striking in the UK, with a tenfold increase in men and fivefold increase in women in little more than a single generation. Prognosis is poor with a 5-year relative survival rate of less than 10%. The main known risk factors are gastro-oesophageal reflux, obesity (predominantly mediated by intra-abdominal adipose tissues) and smoking. Barrett's oesophagus is a precancerous lesion, however, the risk of degeneration has been overestimated. In population-based studies the annual risk of adenocarcinoma varied between 0.12% and 0.14% and its incidence between 1.2 and 1.4 per 1000 person-years. Only 5% of subjects with Barrett's oesophagus die of oesophageal adenocarcinoma. On the basis of recent epidemiological data, new surveillance strategies should be developed. The purpose of this review is to focus on the epidemiology and risk factors of oesophageal adenocarcinoma.

Abstract
BACKGROUND AND AIM The presence of an association between Barrett's metaplasia and colonic neoplasia has remained controversial. The aim of the study was to test the presence of this association, using a large national database. METHODS From a computerized database of surgical pathology reports, we selected 203,000 subjects who underwent colonoscopy and esophago-gastro-duodenoscopy with biopsy results available from both procedures. In a case-control study we compared the occurrence of Barrett's metaplasia in patients with and without various types of colonic neoplasms. RESULTS Barrett's metaplasia occurred more frequently among patients with hyperplastic polyps (OR = 2.14, 95 % CI 2.02-2.27), adenomatous polyps (2.52, 2.41-2.64), advanced adenomas (2.10, 1.90-2.32), villous adenomas or adenomas with high-grade (HG) dysplasia (2.45, 2.28-2.64), and colonic adenocarcinomas (1.75, 1.39-2.22). The association between Barrett's metaplasia and colonic neoplasm applied similarly to polyps of different size, number and location within the large bowel. These types of association could also be confirmed when analyzed separately for Barrett's metaplasia characterized by low-grade or HG dysplasia, as well as esophageal adenocarcinoma. CONCLUSIONS The data support the existence of a true association between Barrett's metaplasia and various types of colonic neoplasm. The association may be more interesting for its potential insights into the pathogenesis of the two disorders than its actual clinical implications.

Abstract
BACKGROUND & AIMS Understanding the causes of death in people with Barrett's esophagus (BE) could guide evidence-based practice in the follow-up of these patients. METHODS We identified individuals diagnosed with BE in the UK's Clinical Practice Research Datalink and linked their information with that from England's Hospital Episode Statistics database. Eligible patients (N = 8448) were matched with individuals without BE for age, sex, and general practice (controls, N = 155,212). Causes of death were obtained from the UK's Office for National Statistics. Cox proportional hazard regression, excluding data from the first year of follow-up, was used to estimate hazard ratios and cumulative mortality. Absolute excess risks were calculated by subtracting cause-specific mortality values of controls from those of patients with BE. RESULTS Compared with the control population, patients with BE had increased risks of death from neoplasms and from respiratory and digestive causes but not from circulatory disorders. The annual mortality rate from esophageal cancer among patients with BE was 0.14%; 4.5% of deaths among these patients resulted from this cancer, leading to a cumulative 10-year risk of almost 2%. Nonetheless, the largest single cause of death among patients with BE was ischemic heart disease (5.6 per 1000 patients); 168 patients with BE died of this cause, nearly 4-fold the number that died of esophageal cancer. CONCLUSIONS Among patients with BE, approximately 2% will die of esophageal cancer within 10 years. However, patients with BE died more frequently of other causes, such as ischemic heart disease. Evidence-based strategies are available to prevent this disease and might be more cost-effective for reducing mortality among patients with BE.

Abstract
UNLABELLED BACKGROUND& AIMS: Proton pump inhibitors and nonsteroidal anti-inflammatory drugs might prevent esophageal adenocarcinoma in patients with Barrett's esophagus (BE), but there are limited data from clinical trials to support this concept. We conducted a randomized, double-blind, placebo-controlled, phase 2 trial to assess the effects of the combination of aspirin (3 different doses) and esomeprazole on tissue concentrations of prostaglandin (PG) E(2) in patients with BE with no dysplasia or low-grade dysplasia. METHODS Participants were recruited through the multicenter Cancer Prevention Network and randomly assigned to groups that were given 40 mg esomeprazole twice daily in combination with an aspirin placebo once daily (arm A; n = 30), with 81 mg aspirin once daily (arm B; n = 47), or with 325 mg aspirin once daily (arm C; n = 45) for 28 days. We collected esophageal biopsy specimens before and after the intervention period to determine the absolute change in mean concentration of PGE(2) (the primary end point). RESULTS Based on data from 114 patients, baseline characteristics were similar among groups. The absolute mean tissue concentration of PGE(2) was reduced by 67.6 ± 229.68 pg/mL in arm A, 123.9 ± 284.0 pg/mL in arm B (P = .10 vs arm A), and 174.9 ± 263.62 pg/mL in arm C (P = .02 vs arm A). CONCLUSIONS In combination with esomeprazole, short-term administration of higher doses of aspirin, but not lower doses or no aspirin, significantly reduced tissue concentrations of PGE(2) in patients with BE with either no dysplasia or low-grade dysplasia. These data support further evaluation of higher doses of aspirin and esomeprazole to prevent esophageal adenocarcinoma in these patients. Clinical trial registration number NCT00474903.

Abstract
The incidence of esophageal adenocarcinoma (EAC) has increased exponentially in the last 3 decades. Barrett's esophagus (BE) is the only known precursor of EAC. Patients with BE have a greater than 40 folds higher risk of EAC compared with the general population. Recent years have witnessed a revolution in the clinical and molecular research related to BE. However, several aspects of this condition remain controversial. Data regarding the true prevalence of BE have varied widely. Recent studies have suggested a lower incidence of EAC in nondysplastic BE (NDBE) than previously reported. There is paucity of prospective data showing a survival benefit of screening or surveillance for BE. Furthermore, the ever-increasing emphasis on healthcare cost containment has called for reexamination of the screening and surveillance strategies for BE. There is a need for identification of reliable clinical predictors or molecular biomarkers to risk-stratify patients who might benefit the most from screening or surveillance for BE. Finally, new therapies have emerged for the management of dysplastic BE. In this paper, we highlight the key areas of controversy and uncertainty surrounding BE. The paper discusses, in detail, the current literature about the molecular pathogenesis, biomarkers, histopathological diagnosis, and management strategies for BE.
