Understanding the malignant potential of gastric metaplasia of the oesophagus and its relevance to Barrett's oesophagus surveillance: individual-level data analysis. Gut 2024; 73:729-740. [PMID: 37989565 PMCID: PMC11041591 DOI: 10.1136/gutjnl-2023-330721] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 11/01/2023] [Indexed: 11/23/2023]
Abstract
OBJECTIVE Whether gastric metaplasia (GM) of the oesophagus should be considered as Barrett's oesophagus (BO) is controversial. Given concern intestinal metaplasia (IM) may be missed due to sampling, the UK guidelines include GM as a type of BO. Here, we investigated whether the risk of misdiagnosis and the malignant potential of GM warrant its place in the UK surveillance. DESIGN We performed a thorough pathology and endoscopy review to follow clinical outcomes in a novel UK cohort of 244 patients, covering 1854 person years of follow-up. We complemented this with a comparative genomic analysis of 160 GM and IM specimens, focused on early molecular hallmarks of BO and oesophageal adenocarcinoma (OAC). RESULTS We found that 58 of 77 short-segment (<3 cm) GM (SS-GM) cases (75%) continued to be observed as GM-only across a median of 4.4 years of follow-up. We observed that disease progression in GM-only cases and GM+IM cases (cases with reported GM on some occasions, IM on others) was significantly lower than in the IM-only cases (Kaplan-Meier, p=0.03). Genomic analysis revealed that the mutation burden in GM is significantly lower than in IM (p<0.01). Moreover, GM does not bear the mutational hallmarks of OAC, with an absence of associated signatures and driver gene mutations. Finally, we established that GM found adjacent to OAC is evolutionarily distant from cancer. CONCLUSION SS-GM is a distinct entity from SS-IM and the malignant potential of GM is lower than IM. It is questionable whether SS-GM warrants inclusion in BO surveillance.

Esophageal adenocarcinoma heterogeneity in clinicopathology and prognosis: A single center longitudinal study of 146 cases over a 20-year period. Ann Diagn Pathol 2024; 70:152285.

Abstract
Recent genomic studies suggest that esophageal adenocarcinoma (EAC) is not homogeneous and can be divided into true (tEAC) and probable (pEAC) groups. We compared clinicopathologic and prognostic features between the two groups of EAC. Based on endoscopic, radiologic, surgical, and pathologic reports, tumors with epicenters beyond 2 cm of the gastroesophageal junction (GEJ) were assigned to the tEAC group (N = 63), while epicenters within 2 cm of, but not crossing the GEJ, were allocated to the pEAC group (N = 83). All 146 consecutive patients were male (age: median 70 years, range: 51-88) and White-predominant (98.6 %). There was no significant difference in gastroesophageal reflux disease, obesity, comorbidity, and the prevalence of Barrett's esophagus, and cases diagnosed during endoscopic surveillance. However, compared to the pEAC group, the tEAC group had significantly more cases with hiatal hernia (P = 0.003); their tumors were significantly smaller in size (P = 0.007), more frequently with tubular/papillary adenocarcinoma (P = 0.001), had fewer cases with poorly cohesive carcinoma (P = 0.018), and demonstrated better prognosis in stage I disease (P = 0.012); 5-year overall survival (34.9 months) was significantly longer (versus 16.8 months in pEACs) (P = 0.043). Compared to the patients without resection, the patients treated with endoscopic or surgical resection showed significantly better outcomes, irrespective of stages. We concluded that EACs were heterogeneous with two distinct tEAC and pEAC groups in clinicopathology and prognosis; resection remained the better option for improved outcomes. CONDENSED ABSTRACT: Esophageal adenocarcinoma can be divided into true or probable groups with distinct clinicopathology and better prognosis in the former than in the latter. we showed that resection remained the better option for improved outcomes.

Abstract
BACKGROUND Achalasia and other esophageal dysmotility disorders mimicking achalasia can be associated with cancer. This study aimed to review the main mechanisms for which cancer may develop in esophageal dysmotility disorder patients. METHODS A narrative review was performed. RESULTS The mechanism for developing squamous cell carcinoma and adenocarcinoma are discussed. Besides, achalasia-like syndromes related to familial KIT-gene mutation and pseudoachalasia are discussed. CONCLUSIONS Knowing the main mechanism for which achalasia can be related to cancer is essential for clinicians to conduct the proper investigation, surveillance, and treatment.

Neoplasia Detection Rate in Barrett's Esophagus and Its Impact on Missed Dysplasia: Results from a Large Population-Based Database. Clin Gastroenterol Hepatol 2021; 19:922-929.e1. [PMID: 32707339 PMCID: PMC7854811 DOI: 10.1016/j.cgh.2020.07.034] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 07/12/2020] [Accepted: 07/16/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS It is a challenge to detect dysplasia in Barrett's esophagus (BE) and esophageal adenocarcinomas (EACs) are missed in 25%-33% of cases. The neoplasia detection rate (NDR), defined as the rate of high-grade dysplasia (HGD) or EAC detection during initial surveillance endoscopy, has been proposed as a quality metric for endoscopic evaluation of patients with BE. However, current estimates are from referral center cohorts, which might overestimate NDR. Effects on rates of missed dysplasia are also unknown. We analyzed data from a large cohort of patients with BE to estimate the NDR and factors associated with it, and assess the effects of the NDR on the rate of missed dysplasia. METHODS We analyzed data from 1066 patients in the Rochester Epidemiology Project-linked medical record system, a population-based cohort of patients with BE (confirmed by review of the endoscopic and histologic reports) from 11 southeastern Minnesota counties from 1991 through 2019. Biopsies reported to contain dysplasia were confirmed by expert gastrointestinal pathologists. The NDR was calculated as the rate of HGD or EAC detected by histologic analyses of biopsies collected during the first surveillance endoscopy. Patients without HGD or EAC at their initial endoscopy (n = 391) underwent repeat endoscopy within 12 months; HGD or EAC detected at the repeat endoscopy were considered to be missed on index endoscopy. Factors associated with NDR and missed dysplasia were identified using univariate and multivariate logistic regression models. RESULTS The NDR was 4.9% (95% CI, 3.8-6.4); 3.1% of patients had HGD, 1.8% had EAC, and 10.6% had low-grade dysplasia. Factors associated with higher rates of detection of neoplasia included older age, male sex, smoking, increasing length of BE, and surveillance endoscopies by gastroenterologists. This NDR was associated with a substantially lower rate of missed dysplasia (13%). CONCLUSIONS In an analysis of 1066 patients with BE in a population-based cohort, we found a lower NDR and lower rate of missed dysplasia than previously reported. NDR may have value as a quality metric in BE surveillance if validated in other cohorts.

Abstract
In the United States, the incidence of esophageal adenocarcinoma increased markedly since the 1970s with a recent stabilization. Despite evolving screening and surveillance strategies to diagnose, risk triage, and intervene in Barrett's esophagus patients to prevent esophageal adenocarcinoma, most cases present with advanced disease and poor resultant survival. Epidemiologic studies have identified the main risk factors for these conditions, including increasing age, male sex, white race, gastroesophageal reflux disease, abdominal obesity, cigarette smoking, and lack of infection with Helicobacter pylori. This review summarizes the current epidemiologic evidence with implications for screening and surveillance in Barrett's esophagus and esophageal adenocarcinoma.

Abstract
AIMS Recent studies have suggested that oesophageal submucosal gland (ESMG) ducts harbour progenitor cells that may contribute to oesophageal metaplasia. Our objective was to determine whether histological differences exist between the ESMGs of individuals with and without oesophageal adenocarcinoma (EAC). METHODS AND RESULTS We performed histological assessment of 343 unique ESMGs from 30 control patients, 24 patients with treatment-naïve high-grade columnar dysplasia (HGD) or EAC, and 23 non-EAC oesophagectomy cases. A gastrointestinal pathologist assessed haematoxylin and eosin-stained ESMG images by using a scoring system that assigns individual ESMG acini to five histological types (mucous, serous, oncocytic, dilated, or ductal metaplastic). In our model, ductal metaplastic acini were more common in patients with HGD/EAC (12.7%) than in controls (3.5%) (P = 0.006). We also identified greater proportions of acini with dilation (21.9%, P < 0.001) and, to a lesser extent, ductal metaplasia (4.3%, P = 0.001) in non-EAC oesophagectomy cases than in controls. Ductal metaplasia tended to occur in areas of mucosal ulceration or tumour. CONCLUSIONS We found a clear association between ductal metaplastic ESMG acini and HGD/EAC. Non-EAC cases had dilated acini and some ductal dilation. Because ESMGs and ducts harbour putative progenitor cells, these associations could have significance for understanding the pathogenesis of EAC.

Esophageal Adenocarcinoma and Its Rare Association with Barrett's Esophagus in Henan, China. PLoS One 2014; 9:e110348.

Abstract
Incidence of esophageal adenocarcinoma (EAC) has increased sharply in Western Europe and United States over the past three decades. Nearly all cases of EAC in the west are thought to be associated with Barrett's esophagus (BE) at the time of diagnosis. Regions in the Henan province of China have one of world's highest incidences of esophageal cancer, yet recent temporal trends in the relative rates of EAC with respect to esophageal squamous-cell carcinoma (ESCC), as well as its association with Barrett's esophagus (BE), have not been reported. In this report, we present large-scale longitudinal clinical and histological data on 5401 esophageal cancers (EC) patients diagnosed during the recent 10-year period (2002-2011) at Henan Cancer Hospital, China. All 217 esophageal adenocarcinoma (EAC) patients from these 5401 EC patients were examined to better understand the relationship between Barrett's esophagus (BE) and EAC. We found that EAC was relatively rare and accounted for approximately 5% of all esophageal cancers each year during 2002-2011. There is no evidence of significant temporal trends in the rate of EAC relative to ESCC. Only 10 out of 217 (4.6%) EAC cases were detected to have any evidence of Barrett's esophagus. This result raises the possibility of a different etiological basis for EAC in China motivating more detailed epidemiological, clinical and molecular characterization of EAC in China in order to better understand the neoplastic development of EAC.

Abstract
Adenocarcinoma of the distal esophagus and esophagogastric junction continues to rise in incidence. An intestinal metaplasia (Barrett esophagus)-dysplasia-carcinoma sequence induced by gastroesophageal reflux disease is well established. However, a significant number of adenocarcinomas in the vicinity of the esophagogastric junction are seen in the background of gastric/cardiac-type mucosa without intestinal metaplasia. Thus, the aim of this study was to investigate the role of Barrett esophagus (intestinal-type mucosa) in the classification and prognosis of tumors of the distal esophagus and esophagogastric junction. Clinicopathological and molecular characteristics were examined in 157 consecutively resected adenocarcinomas of the distal esophagus and esophagogastric junction and were compared between tumors arising in association with intestinal-type and cardiac-type mucosa. Intestinal-type mucosa-associated adenocarcinomas were more likely to be associated with younger age (P=0.0057), reflux symptoms (P<0.0001), proximal location (P=0.0009), lower T stage (P<0.0001), fewer nodal metastases (P=0.0001), absence of lymphatic (P<0.0001), venous (P=0.0060) or perineural (P<0.0001) invasion. Histologically, intestinal-type mucosa-associated tumors were more likely to be low-grade glandular tumors (P=0.0095) of intestinal or mixed immunophenotype (P=0.015) and express nuclear β-catenin (P=0.0080), whereas tumors arising in a background of cardiac-type mucosa were more frequently associated with EGFR amplification (P=0.0051). Five-year overall survival rate was significantly higher in patients with intestinal-type mucosa-associated tumors (28 vs 9%, P=0.0015), although no survival benefit was seen after adjusting for potential confounders. Our findings support the theory that multiple distinct pathways of tumorigenesis exist in the vicinity of the esophagogastric junction, including one in which tumors arise from dysplastic intestinal metaplasia (intestinal pathway), and one potentially involving dysplasia of the cardiac-type mucosa (non-intestinal pathway). Additional studies are warranted to further clarify their pathogenesis and the molecular mechanisms involved.

Abstract
Background Investigation of the expression of an intestinal stem cell marker in esophageal adenocarcinomas (EAC) with and without Barrett's Esophagus (BE), with respect to a cancer stem cell (CSC) hypothesis. Materials and methods Expression of a putative intestinal stem cell marker LgR5 was analyzed in esophageal cancer specimen (n = 70: 41 EAC with BE, 19 EAC without BE, and n = 10 esophageal squamous-cell carcinomas, ESCC) and in the adenocarcinoma cell line OE-33. Ki-67 and Cdx-2 were co-labelled with LgR5 in double staining experiments. Immunhistochemical expression results were confirmed by RT-PCR and correlated with tumor stage and five-year survival rates. Results LgR5was found expressed in 35 of 41 (85%) EAC with BE and in 16 of 19 (81%) EAC without BE. By contrast, LgR5 was not found to be expressed in ESCC. Quantification of immunolabeling showed 15% LgR5+ cells in EAC with BE, 32% LgR5+ cells in adjacent BE and 13% in EAC without BE. Immunofluorescence double staining experiments with LgR5 and Ki-67 revealed a subpopulation (~5%) of proliferating LgR+/Ki-67+ cells. On mRNA-level, expression of LgR5 was higher in BE in comparison to EAC (p = 0.0159). High levels of LgR5 expression in BE associated EAC were associated with poorer survival in univariate analysis. Conclusion The stem cell marker LgR5 is expressed in EAC, irrespective of association with BE, and appears to have negative impact on survival. The subset of proliferating LgR5+ cells (<5%) might resemble rapidly cycling CSCs, which needs to be substantiated in further investigations.

Abstract
Background Esophageal adenocarcinomas (EACs) arise due to gastroesophageal reflux, with Barrett's esophagus (BE) regarded as precancerous lesion. Matrix metalloproteinases (MMPs) might play a role during the multistep carcinogenetic process. Methods Expression of MMP-1 and -13 was analyzed in esophageal cancer (n = 41 EAC with BE, n = 19 EAC without BE, and n = 10 esophageal squamous-cell carcinomas, ESCC), furthermore in BE without intraepithelial neoplasia (IN) (n = 18), and the cell line OE-33. MMP-1 was co-labelled with Ki-67 (proliferation), Cdx-2 (marker for intestinal metaplasia, BE) and analyzed on mRNA level. MMP-1 staining results were correlated with clinicopatholocical parameters. Results On protein level, MMP-1 expression was found in 39 of 41 (95%) EAC with BE, in 19 of 19 (100%) EAC without BE, in 6 of 10 (60%) ESCC, and in 10 of 18 (56%) BE without IN. No expression of MMP-13 was found in these specimens. Quantification showed 48% MMP-1 positive cells in EAC with BE, compared to 35% in adjacent BE (p < 0.05), 44% in EAC without BE, 32% in ESCC, and 4% in BE without IN. Immunofluorescence double staining experiments revealed increased MMP-1 expressing in proliferating cells (MMP-1+/Ki-67+) (r = 0.943 for BE and r = 0.811 for EAC). On mRNA-level, expression of MMP-1 was significantly higher in EAC compared to BE (p = 0.01) and confirmed immunohistochemical staining results. High MMP-1 levels were associated with lymph node metastases but not with poorer survival (p = 0.307). Conclusions Our findings suggest that MMP-1 plays a role as preinvasive factor in BE-associated EAC. Expression of MMP-1 in proliferating BE and EAC cells suggest malignant proliferation following the clonal expansion model.

Abstract
BACKGROUND Prolonged gastro-oesophageal reflux resulting in columnar metaplasia of the oesophagus is the main risk factor for oesophageal adenocarcinoma. AIM To examine the duration of symptoms and associations of different symptoms with the development of columnar-lined oesophagus, dysplasia and adenocarcinoma. METHODS UK multicentre cohort study of patients with columnar-lined oesophagus whose date of symptom onset (1082 patients) and/or types of symptoms reported (1681 patients) were documented. Follow-up was examined by analysis of histological reports from the registering centers. RESULTS Symptoms of dysphagia/odynophagia and nausea/vomiting were associated with development of dysplasia. High-grade dysplasia and adenocarcinoma were associated with dysphagia/odynophagia and weight loss. Median duration from symptom onset to detection of columnar-lined oesophagus without intestinal metaplasia: 2.6 years, columnar-lined oesophagus with intestinal metaplasia: 5.0 years, indefinite changes for dysplasia: 19.3 years and low-grade dysplasia: 30.0 years. One tenth of patients had developed high-grade dysplasia at 9.6 years and one tenth had developed adenocarcinoma at 13.8 years from symptom onset. CONCLUSIONS In patients with columnar-lined oesophagus, symptoms of dysphagia/odynophagia and nausea/vomiting were associated with a higher risk of development of dysplasia and adenocarcinoma. There is a trend for longer duration of symptoms to the detection of dysplasia.

Abstract
BACKGROUND The laparoscopic transhiatal esophagectomy for benign or malignant disease is a complex operation associated with a high rate of morbidity and mortality. In the last decade this procedure gained popularity and acceptance for treatment of the esophagus cancer and other benign diseases. AIM To perform a retrospective analysis in patients with esophageal cancer that was underwent a laparoscopic transhiatal esophagectomy, demonstrated pre and post operative complications and immediate result. METHODS From November 1993 to June 2005, 72 patients underwent laparoscopic transhiatal esophagectomy. Sixty-four with malignant neoplasm of esophagus. The males are predominant, and the mean age was 56.5 years. The abdominal part of the operation was totally laparoscopic and the cervical one was made the conventional way. The stomach was pulled up to the neck by the posterior mediastinum. RESULTS The laparoscopic transhiatal esophagectomy was initiated in 64 patients. Four patients were converted to open surgery. The mean operation time was 153 minutes. The incidence of cervical fistula was 14.06%. The mortality rate 5.6%. CONCLUSION Laparoscopic transhiatal esophagectomy is a secure option in experience centers. The morbility is low, with a faster return to normal activity. Maybe in fact this procedure may be reminded and ponder in the treatment of esophageal disease.

Abstract
Fluorescence diagnosis following oral administration of 5-aminolevulinic acid (5-ALA) has shown to enable the sensitive visualization of intestinal metaplasia, dysplasia and early carcinoma in Barrett's esophagus. Once being established, this technique will be a potential alternative to today's standard diagnosis, i.e. four-quadrant random biopsies which are taken every 1-2 cm of the esophagus for histopathological analysis. In order to further improve this methodology, topical application of lipophilic 5-ALA esters to the esophagus could be advantageous in terms of fluorescence contrast and fluorescence intensity in the target tissue, adverse side effects, as well as application time. Therefore, the aim of this study was to develop a bioadhesive formulation loaded with hexylaminolevulinate (HAL) targeting the esophageal lining. In the present study, different mucoadhesive gels including poloxamer 407, cross-linked polyacrylic acid, hydroxypropylmethylcellulose, sodium carboxymethylcellulose and chitosan have been evaluated with respect to bioadhesion to the esophagus using an ex vivo rat model and a clinical study on healthy volunteers. In order to visualize the mucoadhesive properties of the formulations, a blue dye was incorporated as contrast agent. Chitosan has shown the best esophageal adhesion both in vitro and in vivo. Furthermore, using the in vitro release profiles from chitosan loaded with 40 mM of HAL, one can estimate that after a residence time of 10 min on the esophageal wall, the amount of HAL delivered to the epithelium will be sufficient to perform fluorescence diagnosis of Barrett's esophagus following swallowing of this formulation.

Abstract
BACKGROUND Laparoscopic transhiatal esophagectomy, indicated for benign and malignant esophageal diseases, is a complex operation, often associated with a high rate of morbidity and mortality. During the past decade this technique has became well accepted among specialized surgeons for the treatment of esophageal cancer, avoiding thoracotomy and reducing open access complications. The aim of the present study was to retrospectively analyze patients with esophageal cancer who underwent laparoscopic transhiatal esophagectomy. METHODS From November 1993 to August 2006, 78 patients underwent laparoscopic transhiatal esophagectomy. There were 68 cases of esophageal cancer (57 males and 21 females, age range = 28-73 years) with a predominant rate of squamous cell carcinoma (60.2%). RESULTS The conversion rate was 6.4%. The mean operative time was 153 min with a 12.8% rate of cervical leak and a postoperative (30-day) mortality rate of 5.1%. The four-year survival rate was 19% as determined within a subgroup of 21 patients whose followup during the period was possible. CONCLUSIONS Laparoscopic transhiatal esophagectomy is a safe alternative for experienced professionals. This access can improve mortality, hospital stay, and other outcomes when compared with open methods.

Abstract
OBJECTIVE A recent study of adenocarcinoma of the oesophagus (ACO) incidence rates in Denmark showed a steep fall in the over-80 population, interpreted as the result of a decline in the prevalence of Barrett's oesophagus (BO) in this age group, for which three hypotheses were advanced: the specific mortality from ACO and, superimposed, either excess mortality from causes of death unrelated to ACO or a birth cohort effect. The aim of this study was to create models estimating the BO population fitting each of these three hypotheses, in order to select the most plausible hypothesis and to gain insight into the Danish BO population. MATERIAL AND METHODS Models were designed for these three hypotheses, conforming to the generally accepted 0.4-0.5% annual ACO incidence in BO patients. These models employed expectation-maximization (EM) algorithms, Danish life tables and the observed ACO incidence rates. The models enabled the estimation of a BO population for each hypothesis. RESULTS After testing against set criteria, the most plausible model was found to be that describing a birth cohort effect which predicted a +/-5% annual rise in the prevalence of BO and, consequently, in the incidence rate of ACO in Denmark. This prediction was borne out over the subsequent decade. CONCLUSIONS This rising ACO incidence rate is likely to continue into the foreseeable future. The use of EM algorithms enabled a first estimate of the BO population at risk of ACO, although, owing to the limitations imposed by the models, the age- and gender-specific ACO risk for the entire Danish BO population could not as yet be ascertained.

Abstract
BACKGROUND Barrett's oesophagus is present in 8-10% of patients with gastro-oesophageal reflux disease (GERD). AIM We performed a cohort study to determine the incidence of Barrett's oesophagus in patients with chronic heartburn symptoms. METHODS We identified patients, with GERD and/or Barrett's oesophagus between 1998 and 2004 by primary or secondary International Classification of Diseases (ICD-9) codes of 530.81 and/or 530.2, who had two or more oesophagogastroduodenoscopies performed at least 6 months apart. RESULTS We screened 11 040 patients (41 390 random data entries by ICD-9 code) and enrolled 515 (4.6%) GERD patients and 169 (1.5%) Barrett's oesophagus patients. The mean (+/-s.d.) number of oesophagogastroduodenoscopies in the GERD cohort was 3.2 +/- 1.8 (range: 2-15) over 3.4 +/- 2.2 (range: 0.5-11) years. None of the 412 (80%) GERD patients with non-erosive disease developed Barrett's oesophagus over a mean follow-up time of 3.4 +/- 2.2 years (95% CI: 0-0.9%). Five (1%) of the 103 GERD patients with erosive oesophagitis developed subsequent Barrett's oesophagus. Fifty-seven per cent of the GERD patients were on PPI therapy at the time of index endoscopy. None of the 169 Barrett's oesophagus patients had normal index oesophagogastroduodenoscopies within a mean retrospective time period of 4.5 +/- 2.8 years (95% CI: 0-2%). Using the ICD-9 code of 530.2 as a predictor of the presence of Barrett's oesophagus, the sensitivity was 79% with a specificity of 88%. CONCLUSION The majority of patients with GERD do not appear to develop Barrett's oesophagus when it is not present on the index endoscopy.

Abstract
OBJECTIVE To identify risk factors for esophageal adenocarcinoma (EAC) in patients with Barrett's esophagus (BE). METHODS A hospital-based case-control study was performed in which 91 cases with EAC and 244 controls with histologically confirmed BE (>2 cm) with no dysplasia or low-grade dysplasia were included. Information on demographic, anthropometric, and lifestyle characteristics, physical activity levels, working posture, family history, gastroesophageal reflux disease (GERD) symptoms, and medication use was collected by questionnaire. RESULTS Cases more often were current smokers (odds ratio 3.7, 95% confidence interval 1.4-9.9), more often had a body mass index >25 assessed at age 20 (2.6, 1.2-5.5), and more frequently had been working in a stooped posture at age 20 (2.0, 1.1-3.9), compared to controls. In addition, cases less often experienced symptoms of heartburn (0.3, 0.2-0.5) and less frequently used proton pump inhibitors (0.1, 0.05-0.2), compared to controls, whereas use of nonsteroidal anti-inflammatory drugs/aspirin was more common among cases (1.8, 1.1-3.2). Cases more often were men, compared to controls (91%vs 67%, p < 0.001). CONCLUSION In patients with BE, the risk of EAC is related to risk factors for GERD, which is, however, asymptomatic. As these risk factors are common in Western countries, they are probably not helpful in individualization of surveillance intervals.

Abstract
BACKGROUND Barrett's esophagus and gastroesophageal reflux disease (GERD) are recognized to predispose to esophageal adenocarcinoma. Abdel-Latif and colleagues recently suggested that esophageal adenocarcinoma patients with GERD might be resistant to multimodality treatment. In this study, we investigated potential differences in clinical outcomes in esophageal adenocarcinoma patients based on the presence of identifiable Barrett's mucosa and/or history of symptomatic GERD. METHODS Eighty-four patients with resectable esophageal adenocarcinoma, who completed the planned preoperative chemoradiation and underwent a potentially curative esophageal resection were retrospectively evaluated. Postoperative survival was compared between patients with or without underlying Barrett's esophagus and history of symptomatic GERD. Patients with pathologic complete response (path CR) and those with partial or no response (path PR) were compared to determine if presence of Barrett's esophagus and history of symptomatic GERD influence the path CR rates. RESULTS We found significantly lower postoperative survival in patients with Barrett's associated adenocarcinoma (vs adenocarcinoma arising de novo, p = 0.031) and patients with symptomatic GERD (vs patients without symptomatic GERD, p = 0.019). Furthermore, the subset of patients with path PR (vs path CR) after chemoradiation have a significantly higher proportion of patients with Barrett's esophagus (HR = 4.38, confidence interval [CI] = 1.39 to 13.83, p = 0.012) and patients with GERD (HR = 2.71, CI = 1.13 to 6.50, p = 0.026). CONCLUSIONS Patients with esophageal adenocarcinoma may have differences in response to preoperative chemoradiation based on the presence of Barrett's esophagus and history of symptomatic GERD.

Abstract
BACKGROUND Adenocarcinoma limited to the esophagus (ACE) arises in Barrett's esophagus (BE). The incidence of ACE is therefore restricted to this BE subpopulation, whose size is unknown and which is for 95% unidentified. AIMS To determine the age- and gender-specific incidence rates of ACE, limited to the BE subpopulation, within a defined geographical area and to compare them with those of squamous cell carcinoma of the esophagus (SCC), which can affect the entire population. METHODS The age- and gender-specific incidence rates for ACE and adenocarcinoma of the cardia (AGC) were calculated after an expert panel classified 87% of all cases of adenocarcinoma of the esophagus reported to the Danish Cancer Registry over a 6-yr period as ACE or AGC. RESULTS The age-specific incidence rates of ACE for males rose from 0.09/10(5) (30-34 yr) to 14.14/10(5) (80-84 yr), falling to 7.2/10(5) (85+ yr), for females from 0.19/10(5) (45-49 yr) to 2.79/10(5) (80-84 yr), falling to 2.43/10(5) (85+ yr) and yielding a gender ratio of 5.9:1; AGC demonstrated a similar pattern and a gender ratio of 4.26:1. However, the incidence rates of SCC continued rising after the age of 80 yr, with a gender ratio of 2.46:1. CONCLUSIONS The continuing rise in the SCC incidence rates in the elderly demonstrated that the unexpected decline and fall in the incidence rates of ACE over the age of 80 yr did not result from underdiagnosis but were most probably caused by a declining prevalence rate of BE, restricting the elderly BE subpopulation at risk of developing ACE.

Abstract
BACKGROUND Both the demographics underlying the sex ratio in the prevalence of Barrett's esophagus (BE) and the status of BE without intestinal metaplasia (IM) are unclear. AIMS To establish the demographics of histologically proven BE, IM+ and IM-, over a 15-yr period from a primary referral, endoscopy unit. PATIENTS AND METHODS For all BE patients aged 20-89 yr, identified between 1982 and 1996, IM+ or IM-, prevalences were calculated per 100 first endoscopies. RESULTS A total of 492 cases of BE, 320 (248 IM+) in males, 175 (127 IM+) in females were identified in 21,899 first endoscopies (10,939 males, 10,960 females). Between ages 20 and 59 yr in males and 20-79 in females, IM+, IM- and all BE prevalences rose by +/-7.36% for each additional year of age (p= 0.92) with, however, a 20-yr age shift between the sexes, resulting in a male:female OR 4.15 95% CI 2.99-5.77. A declining rate of increase in over 59 males resulted in an overall male:female OR 2.14, 95% CI 1.77-2.58. Over the age of 79 yr, BE prevalences/100 first endoscopies fell from a maximum of 5.1 in males and 3.65 in females to 3.38 and 2.53, respectively. CONCLUSION The 4:1 sex ratio and 20-yr age shift between males and females in the prevalence of BE, both IM+ and IM-, found in younger age groups, was the main cause of the overall BE 2:1 sex ratio. The very similar demographics of IM- and IM+ BE suggest they may be two consecutive stages in the same metaplastic process.

Abstract
OBJECTIVE To ascertain the incidence rate of adenocarcinoma in Barrett's esophagus (ACE) in a stable population of 28,000 institutionalized intellectually disabled individuals (IDI) in whom the prevalence rate of Barrett's esophagus (BE) was previously estimated in a representative sample by 24 h pH monitoring and endoscopy, and in which all cases of ACE were ascertained over a 6-year period. These IDI do not smoke or drink alcohol and are known to have exceptionally high prevalence rates of gastro-esophageal reflux disease, and consequently of BE. METHODS A population comprising 52,038 person-years was observed and all cases of ACE were ascertained. On the basis of the representative sample, the percentage of this population with BE was estimated to be 10.8%. ACE incidence rates could then be estimated and compared with those found in a free-living BE cohort after correction for age and gender differences. RESULTS In IDI an incidence rate of ACE of 2.5/1000 person-years was found against 6.3/1000 person-years in the free-living BE cohort. However, the age distributions of the IDI and of the free-living BE cohort were very different, and after correction for this factor there was no significantly lower incidence rate of ACE in the IDI (relative risk, 0.79; P = 0.61). CONCLUSIONS This is the first reported incidence study of ACE in a stable, well-defined population. In contrast to squamous cell carcinoma, our findings suggest only a minor role for smoking and alcohol in the etiology of ACE.

Abstract
Adenocarcinoma of the esophagus and the gastroesophageal junction is the twentieth most common malignancy in the United States. In developed countries, the incidence of esophageal adenocarcinoma is increasing 5% to 10% per year. Despite the use of endoscopy for earlier detection, mortality from esophageal adenocarcinoma has not declined. Using an evidence-based approach, we review screening methods for esophageal adenocarcinoma, including the use of a symptom questionnaire, identification of patients with a family history of Barrett's esophagus, peroral or transnasal endoscopy, barium swallow, fecal occult blood testing, and brush and balloon cytology. Screening has not been shown to reduce rate of progression of Barrett's esophagus to esophageal cancer. Many treatment options for dysplastic Barrett's esophagus or early carcinoma appear effective, but long-term follow-up data are not available. There is currently insufficient evidence supporting population-based screening for Barrett's esophagus. Several risk factors, including severe reflux symptoms, male sex, and obesity, may identify patients with gastroesophageal reflux disease who are at the greatest risk of the development of cancer.

Abstract
BACKGROUND Intestinal metaplasia of the distal esophagus frequently cannot be detected in patients with esophageal adenocarcinoma. It has therefore been questioned whether Barrett's esophagus is the primary precursor lesion of such lesions. We hypothesized that the underlying Barrett's mucosa may be masked by tumor overgrowth in the majority of these patients. METHODS The pretherapeutic endoscopy and biopsy records of 79 patients with locally advanced esophageal adenocarcinoma who had undergone preoperative chemotherapy were reviewed and compared to findings on restaging endoscopy/biopsy and subsequent resection and histopathologic analysis of the resected specimen. RESULTS Pretherapeutic endoscopy and biopsy showed associated Barrett's esophagus in 59/79 patients, whereas there was no evidence of associated intestinal metaplasia in 20/79 patients on extensive biopsies. Following neoadjuvant chemotherapy, Barrett's mucosa was unmasked and later documented by biopsy or histopathologic assessment of the resected specimen in 18 of the latter 20 patients. This resulted in an overall association of Barrett's mucosa with adenocarcinoma in the distal esophagus of 97.4% CONCLUSION Underlying Barrett's mucosa is frequently masked by tumor overgrowth in patients with locally advanced adenocarcinoma of the distal esophagus.

Abstract
Esophageal adenocarcinoma in patients 45 years of age or younger is uncommon. We reviewed our experience with the surgical management of these patients to determine their clinical characteristics, pathologic findings, and treatment results. Thirty-two patients were identified through our surgical pathology database, and their medical records were reviewed to determine clinical characteristics, treatment, treatment-associated mortality, tumor staging, presence of Barrett's mucosa, and survival. In our series, patients were white (100%) males (96.9%) with a history of reflux (56.3%), cigarette smoking (40.6%), and alcohol consumption (59.4%), who presented with progressive solid food dysphagia (78.1%). A prior diagnosis of Barrett's mucosa or use of antireflux medications was noted in five patients each (15.6%). There were no operative deaths. Actuarial survival was 81.1% (95% confidence interval [CI] 66.1 to 96.2) at 12 months, 68.5% (95% CI 49.5 to 87.5) at 24 months, and 56.9% (95% CI 34.6 to 79.1) at 60 months. Our findings show that patients with esophageal adenocarcinoma 45 years of age or younger have similar clinical findings to those reported in other large series where the median age is in the sixth or seventh decade of life, supporting a uniform theory of tumor pathogenesis. Esophagectomy may be performed with low mortality, and survival is reasonable for early-stage disease. Young patients with Barrett's esophagus are not immune from the development of adenocarcinoma and need to be screened accordingly.

Abstract
Photodynamic therapy offers the possibility of relatively selective tumour necrosis and normal tissue healing. It has many potential applications but as yet no clear role. Articles, editorials and case reports published primarily in English and listed in Medline/ISI up to April 2000 or identified by a manual search have been reviewed in an attempt to provide a comprehensive overview of the use of photodynamic therapy in the alimentary tract. It is concluded that photodynamic therapy can be an effective treatment for superficial pre-malignant mucosal lesions and early cancers, especially in diffuse disease. Suitable patients include those wishing to avoid surgery, high risk subjects or those in whom other forms of treatment have failed. Superiority over other methods of ablation has not so far been demonstrated. Cheaper and more effective photosensitizers and improved techniques of light delivery are likely to increase the application of photodynamic therapy.

Abstract
We conducted a review of the literature comparing medical treatment with antireflux surgery in patients with Barrett's esophagus (BE). In particular, we wanted to assess the efficacy of medical and surgical therapies in preventing the progression of Barrett's epithelium to dysplasia or adenocarcinoma of the esophagus. In general, few BE patients show complete regression of BE epithelium following medical or surgical therapy. The incidence of developing dysplasia or cancer following surgical therapy appears to be less than with medical therapy; however, there is an insufficient number of current, randomized controlled studies to confirm this. Surveillance of BE is required regardless of treatment. This review suggests that there may be a trend in support of surgery being somewhat better than medical therapy in the prevention of BE progression and adenocarcinoma. We suggest that patients with BE should be considered for antireflux surgery - in particular, certain subgroups of BE patients.
