Abstract
Benign and malignant diseases of the upper gastrointestinal tract show gender-specific differences. The frequent gastroesophageal reflux disease is a prime example: men have an erosive reflux disease more often than women and are also younger at the time of onset. The rate of progression to a metaplastic Barrett's esophagus is also higher in men. In the case of achalasia, there are indications that surgical treatment by laparoscopic Heller's myotomy and semifundoplication 180° according to Dor leads to a markedly better improvement in the symptoms in women compared to men, although they showed a more pronounced dilation of the tubular esophagus. The female hormone status influences the localization and histopathology of adenocarcinoma of the esophagogastric junction and gastric carcinoma. Premenopausal and postmenopausal carcinomas differ significantly in women. In addition, high microsatellite instability (MSI high) is more frequent in women and is associated with a generally significantly better prognosis. The MSI high gastric carcinomas of women show better survival than MSI high carcinomas of men. The future inclusion of gender-specific aspects in studies of the upper gastrointestinal tract is desirable in order to generate adequate data and to enable differentiated treatment stratification in the future.

Sex Differences in Neoplastic Progression in Barrett’s Esophagus: A Multicenter Prospective Cohort Study. Cancers (Basel) 2022; 14:cancers14133240. [PMID: 35805012 PMCID: PMC9264818 DOI: 10.3390/cancers14133240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/20/2022] [Accepted: 06/27/2022] [Indexed: 12/04/2022] Open
Abstract
Simple Summary Barrett’s esophagus (BE) is the only known precursor lesion of esophageal adenocarcinoma (EAC). Endoscopic surveillance plays an important role in the timely detection of neoplastic progression. However, the cost-effectiveness of current surveillance strategies is debatable. Previous studies have shown that male Barrett’s patients have lower neoplastic progression risk than females. However, these studies do not provide a more practical translation of these sex disparities into different surveillance intervals. The current multicenter prospective cohort study aimed to evaluate sex differences in 868 BE patients; not only with respect to neoplastic progression risk, but also concerning the difference in time to detection of high-grade dysplasia (HGD)/EAC: time to neoplastic progression was estimated to be almost twice as low in males than in females. In contrast, the stage of neoplasia appeared to be higher in females. Our results can guide future discussions for sex-specific guidelines, supporting the implementation of neoplastic risk stratification per individual patient in BE surveillance. Abstract Recommendations in Barrett’s esophagus (BE) guidelines are mainly based on male patients. We aimed to evaluate sex differences in BE patients in (1) probability of and (2) time to neoplastic progression, and (3) differences in the stage distribution of neoplasia. We conducted a multicenter prospective cohort study including 868 BE patients. Cox regression modeling and accelerated failure time modeling were used to estimate the sex differences. Neoplastic progression was defined as high-grade dysplasia (HGD) and/or esophageal adenocarcinoma (EAC). Among the 639 (74%) males and 229 females that were included (median follow-up 7.1 years), 61 (7.0%) developed HGD/EAC. Neoplastic progression risk was estimated to be twice as high among males (HR 2.26, 95% CI 1.11–4.62) than females. The risk of HGD was found to be higher in males (HR 3.76, 95% CI 1.33–10.6). Time to HGD/EAC (AR 0.52, 95% CI 0.29–0.95) and HGD (AR 0.40, 95% CI 0.19–0.86) was shorter in males. Females had proportionally more EAC than HGD and tended to have higher stages of neoplasia at diagnosis. In conclusion, both the risk of and time to neoplastic progression were higher in males. However, females were proportionally more often diagnosed with (advanced) EAC. We should strive for improved neoplastic risk stratification per individual BE patient, incorporating sex disparities into new prediction models.

Abstract
Barrett's esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), a cancer with increasing incidence and poor survival. Risk of EAC in patients with BE is higher compared with the general population. Endoscopic screening for BE is performed to identify patients earlier in the metaplasia-dysplasia-carcinoma sequence from BE to EAC to enable eradication therapy. BE screening should be considered in individuals with multiple risk factors for BE and EAC. Challenges to BE screening include the absence of a cost-effective, widely applicable minimally invasive screening tool, gastroesophageal reflux disease centric screening recommendations, and limitations of current endoscopic surveillance practice.

Abstract
Esophageal adenocarcinoma (EAC) is the cancer arising from the esophagus, which frequently develop from Barrett's esophagus (BE). Extracellular vesicles (EVs), particularly exosomes, are nanosized vesicles of endosomal origin released from various types of cells that have been implicated in cancers. However, the significance of circulating exosomes during the progression of BE to EAC remains unknown. Sera exosmal microRNAs were profiled from 13 EAC and 12BE patients compared to 12 healthy controls. We found a substantial dysregulation of exosomal miRNA levels in BE compared to healthy control, and identified a unique signature of 24 up regulated and 14 down regulated miRNAs. Further validation showed exosomal miR-196a, -26b, -21, and -143 expression was significantly higher in BE and continued to have higher levels in EAC compared to healthy controls; while sera exosomal miR-378, -210, -205, and -200c-3p were significantly lower expressed in BE patients compared to compared to controls. Further, miR-378, -210, -205, and -200c-3p continue to have even lower levels in EAC patients compared to BE. Interestingly, sera expression levels of exosomal miR-15a, -16, and -193a-3p were significantly down regulated in BE PD-L1(+) patients; Sera exosomal miR-15a, -15b, -16, and -193a-3p expression levels in EAC PD-L1(+) patients were significantly lower (all p < 0.01) when compared to EAC PD-L1(-) patients. More importantly, the BE-EAC group had longitudinally decreased exosomal expression levels of miR-15a, -15b, -16, and -193a-3p from BE status to their EAC progression. In conclusion, distinct microRNA expression patterns were demonstrated in circulating exosomes from Barrett's esophagus and esophageal adenocarcinoma; Furthermore exosomal microRNAs potentially targeting PD-L1 mRNA were down regulated in PD-L1 (+) BE and EAC patients.

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.

Abstract
Whipple's disease is a rare infectious disease that can be fatal if left untreated. The disease is caused by infection with Tropheryma whipplei, a bacterium that may be more common than was initially assumed. Most patients present with nonspecific symptoms, and as routine cultivation of the bacterium is not feasible, it is difficult to diagnose this infection. On the other hand, due to the generic symptoms, infection with this bacterium is actually quite often in the differential diagnosis. The gold standard for diagnosis used to be periodic acid-Schiff (PAS) staining of duodenal biopsy specimens, but PAS staining has a poor specificity and sensitivity. The development of molecular techniques has resulted in more convenient methods for detecting T. whipplei infections, and this has greatly improved the diagnosis of this often missed infection. In addition, the molecular detection of T. whipplei has resulted in an increase in knowledge about its pathogenicity, and this review gives an overview of the new insights in epidemiology, pathogenesis, clinical manifestations, diagnosis, and treatment of Tropheryma whipplei infections.

Abstract
It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area.

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
Barrett's esophagus (BE) is a well-recognized precursor of esophageal adenocarcinoma (EAC) and is defined as ≥1 cm segment of salmon-colored mucosa extending above the gastroesophageal junction into the tubular esophagus with biopsy confirmation of metaplastic replacement of the normal squamous epithelium by intestinal-type columnar epithelium. The incidence of both BE and EAC has been increasing over the past few decades. As a result, preventing the development of BE by identifying and understanding its modifiable and non-modifiable risk factors may help reduce the incidence of EAC. Over the recent past, a tremendous amount of progress has been made towards improving our knowledge of risk factors and pathogenesis of BE. This article reviews the evidence for the various risk factors for developing BE.

[PMID: 26619962 PMCID: PMC4919075 DOI: 10.1053/j.gastro.2015.11.040] [Citation(s) in RCA: 124] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2015] [Revised: 11/08/2015] [Accepted: 11/18/2015] [Indexed: 02/08/2023]
Abstract
BACKGROUND & AIMS A proportion of patients with Barrett's esophagus (BE) are diagnosed with esophageal adenocarcinoma (EAC) within 1 year of an endoscopic examination that produced negative findings. These cases of missed cancers have not been well studied, despite current surveillance strategies for BE. We performed a systematic review and meta-analysis to determine the magnitude of missed EAC in cohorts of patients with BE. METHODS We searched MEDLINE, EMBASE, and Web of Science from their inception to May 31, 2015 to identify cohort studies of adults with BE (baseline nondysplastic BE ± BE with low-grade dysplasia) and at least a 3-year follow-up period, providing data on missed and incident EACs (diagnosed within 1 year and diagnosed more than 1 year after the initial endoscopy in which BE was diagnosed, respectively). The main outcome measure was pooled proportion of missed and incident EACs (of all EACs detected after initial endoscopy) among BE cohorts, using a random effects model. RESULTS In a meta-analysis of 24 studies reporting on 820 missed and incident EACs, 25.3% were classified as missed (95% confidence interval: 16.4%-36.8%) and 74.7% as incident EACs (95% CI: 63.2%-83.6%), although there was substantial heterogeneity among studies (I2 = 74%). When the analysis was restricted to nondysplastic BE cohorts (15 studies), 23.9% of EACs were classified as missed (95% confidence interval: 15.3%-35.4%; I2 = 0%). In a meta-analysis of 10 studies with follow-up periods of ≥5 years (a total of 239 EACs), 22.0% were classified as missed (95% confidence interval: 8.7%-45.5%), with substantial heterogeneity (I2 = 68%). CONCLUSIONS Among adults with nondysplastic BE (or BE with low-grade dysplasia) at their index endoscopy and at least a 3-year follow-up period, 25% of EACs are diagnosed within 1 year after the index endoscopy. Additional resources should be allocated to detect missed EAC.

Abstract
The incidence of esophageal adenocarcinoma (EAC) has risen sharply in western countries over the past 4 decades. This type of cancer is considered to follow a transitional process that goes from gastro-esophageal reflux disease (GERD) to Barrett's esophagus (BE, a metaplastic condition of the distal esophagus), a precursor lesion and ultimately adenocarcinoma. This spectrum of GERD is strongly predominant in males due to an unidentified mechanism. Several epidemiologic studies have described that the prevalence of GERD, BE and EAC in women is closely related to reproductive status, which suggests a possible association with the estrogen level. Recently, we revealed in an in vivo study that the inactivation of mast cells by the anti-inflammatory function of estrogen may account for the gender difference in the GERD spectrum. Other studies have described the contribution of female steroid hormones to the gender difference in these diseases. Estrogen is reported to modulate the metabolism of fat, and obesity is a main risk factor of GERDs. Moreover, estrogen could confer esophageal epithelial resistance to causative refluxate. These functions of estrogen might explain the approximately 20-year delay in the incidence of BE and the subsequent development of EAC in women compared to men, and this effect may be responsible for the male predominance. However, some observational studies demonstrated that hormone replacement therapy exerts controversial effects in GERD patients. Nevertheless, the estrogen-related endocrine milieu may prevent disease progression toward carcinogenesis in GERD patients. The development of innovative alternatives to conventional acid suppressors may become possible by clarifying the mechanisms of estrogen.

Abstract
BACKGROUND Little is known about differences in Barrett's esophagus (BE) characteristics by sex and race and/or ethnicity or these differences in response to radiofrequency ablation (RFA). OBJECTIVE We compared disease-specific characteristics, treatment efficacy, and safety outcomes by sex and race and/or ethnicity in patients treated with RFA for BE. DESIGN The U.S. RFA patient registry is a multicenter collaboration reporting processes and outcomes of care for patients treated with RFA for BE. PATIENTS Patients enrolled with BE. INTERVENTIONS RFA. MAIN OUTCOME MEASUREMENTS We assessed safety (stricture, bleeding, perforation, hospitalization), efficacy (complete eradication of intestinal metaplasia [CEIM]), complete eradication of dysplasia, and number of treatments to CEIM by sex and race and/or ethnicity. RESULTS Among 5521 patients (4052 men; 5126 white, 137 Hispanic, 82 African American, 40 Asian, 136 heritage not identified), women were younger (60.0 vs 62.1 years) and had shorter BE segments (3.2 vs 4.4 cm) and less dysplasia (37% vs 57%) than did men. Women were almost twice as likely to stricture (odds ratio 1.7; 95% confidence interval, 1.2-2.3). Although white patients were predominantly male, about half of African Americans and Asians with BE were female. African Americans and Asians had less dysplasia than white patients. Asians and African Americans had more strictures than did white patients. There were no sex or race differences in efficacy. LIMITATIONS Observational study with non-mandated paradigms, no central laboratory for reinterpretation of pathology. CONCLUSION In the U.S. RFA patient registry, women had shorter BE segments and less-aggressive histology. The usual tendency toward BE in men was absent in African Americans and Asians. Posttreatment stricture was more common among women and Asians. RFA efficacy did not differ by sex or race.

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
BACKGROUND Length of Barrett's oesophagus (BE) is a risk factor for oesophageal cancer. The underlying mechanisms that determine BE length are nor fully known. AIM To determine if there is a correlation between obesity and length of BE. METHODS Using a population-based study, 381 patients diagnosed with Barrett's oesophagus between 1999 and 2013 were included. Body mass index (BMI) at the time of BE diagnosis was calculated. Upper endoscopy reports were reviewed to obtain the length of BE. Spearman's correlation coefficient was performed to assess the strength of the relationship between Barrett's length and BMI. A multivariate logistic regression analysis was conducted to further examine the association between BMI and length of BE. RESULTS The adjusted odds ratio for each five-point increase in BMI was 1.5 (95% CI 1.24-1.81, P < 0.001). The mean BMI was significantly higher in patients with long segment BE as compared to patients with short segment BE (32.7 vs. 30.3, P = 0.001). There was also a positive trend in long segment BE as patients entered into higher BMI categories (Z = 4.25, P < 0.001). There was a significant correlation between BMI and length of BE (r = 0.25, P < 0.0001). CONCLUSION The study demonstrated a correlation between BMI and the length of Barrett's oesophagus mucosa. Thus, increased BMI is associated with longer segment of Barrett's oesophagus.

Abstract
OBJECTIVE To establish the incidence and risk factors for progression to high-grade intraepithelial neoplasia (HG-IEN) or Barrett's esophageal adenocarcinoma (BAc) in a prospective cohort of patients with esophageal intestinal metaplasia [(BE)]. BACKGROUND BE is associated with an increased risk of BAc unless cases are detected early by surveillance. No consistent data are available on the prevalence of BE-related cancer, the ideal surveillance schedule, or the risk factors for cancer. METHODS In 2003, a regional registry of BE patients was created in north-east Italy, establishing the related diagnostic criteria (endoscopic landmarks, biopsy protocol, histological classification) and timing of follow-up (tailored to histology) and recording patient outcomes. Thirteen centers were involved and audited yearly. The probability of progression to HG-IEN/BAc was calculated using the Kaplan-Meier method; the Cox regression model was used to calculate the risk of progression. RESULTS HG-IEN (10 cases) and EAc (7 cases) detected at the index endoscopy or in the first year of follow-up were considered to be cases of preexisting disease and excluded; 841 patients with at least 2 endoscopies {median, 3 [interquartile range (IQR): 2-4); median follow-up = 44.6 [IQR: 24.7-60.5] months; total 3083 patient-years} formed the study group [male/female = 646/195; median age, 60 (IQR: 51-68) years]. Twenty-two patients progressed to HG-IEN or BAc (incidence: 0.72 per 100 patient-years) after a median of 40.2 (26.9-50.4) months. At multivariate analysis, endoscopic abnormalities, that is, ulceration or nodularity (P = 0.0002; relative risk [RR] = 7.6; 95% confidence interval, 2.63-21.9), LG-IEN (P = 0.02, RR = 3.7; 95% confidence interval, 1.22-11.43), and BE length (P = 0.01; RR = 1.16; 95% confidence interval, 1.03-1.30) were associated with BE progression. Among the LG-IEN patients, the incidence of HG-IEN/EAc was 3.17 patient-years, that is, 6 times higher than in BE patients without LG-IEN. CONCLUSIONS These results suggest that in the absence of intraepithelial neoplastic changes, BE carries a low risk of progression to HG-IEN/BAc, and strict surveillance (or ablative therapy) is advisable in cases with endoscopic abnormalities, LG-IEN or long BE segments.

Abstract
The natural history of Barrett’s esophagus (BE) is difficult to quantify because, by definition, it should describe the course of the condition if left untreated. Pragmatically, we assume that patients with BE will receive symptomatic treatment with acid suppression, usually a proton pump inhibitor, to treat their heartburn. This paper describes the development of complications of stricture, ulcer, dysplasia and adenocarcinoma from this standpoint. Controversies over the definition of BE and its implications in clinical practice are presented. The presence of intestinal metaplasia and its relevance to cancer risk is discussed, and the need to measure the extent of the Barrett’s epithelium (long and short segments) using the Prague guidelines is emphasized. Guidelines and international consensus over the diagnosis and management of BE are being regularly updated. The need for expert consensus is important due to the lack of randomized trials in this area. After searching the literature, we have tried to collate the important studies regarding progression of Barrett’s to dysplasia and adenocarcinoma. No therapeutic studies yet reported show a clear reduction in the development of cancer in BE. The effect of pharmacological and surgical intervention on the natural history of Barrett’s is a subject of ongoing research, including the Barrett’s Oesophagus Surveillance Study and the aspirin and esomeprazole cancer chemoprevention trial with interesting results. The geographical variation and the wide range of outcomes highlight the difficulty of providing an individualized risk profile to patients with BE. Future studies on the interaction of genome wide abnormalities in Barrett’s and their interaction with environmental factors may allow individualization of the risk of cancer developing in BE.

Abstract
BACKGROUND & AIMS The risks of dysplasia and esophageal adenocarcinoma (EAC) are not clear for patients with nondysplastic Barrett's esophagus (NDBE); the rate of progression has been overestimated in previous studies. We studied the incidences of dysplasia and EAC and investigated factors associated with progression of BE. METHODS The BE study is a multicenter outcomes project of a large cohort of patients with BE. Neoplasia was graded as low-grade dysplasia, high-grade dysplasia (HGD), or EAC. Patients followed up for at least 1 year after the index endoscopy examination were included, whereas those diagnosed with dysplasia and EAC within 1 year of diagnosis with BE (prevalent cases) were excluded. Of 3334 patients with BE, 1204 met the inclusion criteria (93.7% Caucasian; 88% male; mean age, 59.3 y) and were followed up for a mean of 5.52 years (6644.5 patient-years). RESULTS Eighteen patients developed EAC (incidence, 0.27%/y; 95% confidence interval [CI], 0.17-0.43) and 32 developed HGD (incidence, 0.48%/y; 95% CI, 0.34-0.68). The incidence of HGD and EAC was 0.63%/y (95% CI, 0.47-0.86). There were 217 cases of low-grade dysplasia (incidence, 3.6%/y; 95% CI, 3.2-4.1). Five and 10 years after diagnosis, 98.6% (n = 540) and 97.1% (n = 155) of patients with NDBE were cancer free, respectively. The length of the BE was associated significantly with progression (EAC <6 cm, 0.09%/y vs EAC ≥ 6 cm, 0.65%/y; P = 0.001). CONCLUSIONS There is a lower incidence of dysplasia and EAC among patients with NDBE than previously reported. Because most patients are cancer free after a long-term follow-up period, surveillance intervals might be lengthened, especially for patients with shorter segments of BE.

Abstract
Incidence rates for oesophageal adenocarcinoma have increased by over 500% during the past few decades without clear reasons. Gastro-oesophageal reflux disease, obesity and smoking have been identified as risk factors, although the demographic distribution of these risk factors is not consistent with the demographic distribution of oesophageal adenocarcinoma, which is substantially more common among whites and males than any other demographic groups. Numerous epidemiological studies have suggested associations between dietary factors and the risks of oesophageal adenocarcinoma and its precursor, Barrett's oesophagus, though a comprehensive review is lacking. The main aim of the present review is to consider the evidence linking dietary factors with the risks of oesophageal adenocarcinoma, Barrett's oesophagus, and the progression from Barrett's oesophagus to oesophageal adenocarcinoma. The existing epidemiological evidence is strongest for an inverse relationship between intake of vitamin C, β-carotene, fruits and vegetables, particularly raw fruits and vegetables and dark green, leafy and cruciferous vegetables, carbohydrates, fibre and Fe and the risk of oesophageal adenocarcinoma and Barrett's oesophagus. Patients at higher risk for Barrett's oesophagus and oesophageal adenocarcinoma may benefit from increasing their consumption of fruits and vegetables and reducing their intake of red meat and other processed food items. Further research is needed to evaluate the relationship between diet and the progression of Barrett's oesophagus to oesophageal adenocarcinoma. Evidence from cohort studies will help determine whether randomised chemoprevention trials are warranted for the primary prevention of Barrett's oesophagus or its progression to cancer.

Abstract
BACKGROUND It is not known whether there have been recent changes in demographic or clinical characteristics among patients newly diagnosed with Barrett's esophagus (BE), which could be a result of changes in disease epidemiology or of screening or surveillance effects, and could have clinical implications. AIMS The aim of this study was to determine whether there has been a shift in age at diagnosis of BE over the past decade. Secondary aims were to determine whether there has been a shift in patient body mass index (BMI) or BE segment length. METHODS An endoscopic database at a tertiary medical center was used to identify all esophagogastroduodenoscopies (EGDs) performed between 1997 and 2007. The cohort was restricted to patients newly diagnosed with BE. Pathology records were reviewed to confirm biopsy findings of intestinal metaplasia (IM). RESULTS BE was diagnosed in 378 subjects between 1997 and 2007. Mean age at diagnosis of BE was 60.7 +/- 14.1 years, with mean BMI of 27.4 +/- 5.2 kg/m(2) and mean BE segment length of 4.7 +/- 3.7 cm. Between 1997 and 2007 there was no significant change in mean age at diagnosis, BMI, BE segment length or in proportion of men versus women newly diagnosed. CONCLUSIONS Despite an increase in volume of EGDs performed in an open-access endoscopy unit between 1997 and 2007, there was no appreciable shift in age at diagnosis of BE. BMI and BE segment length among newly diagnosed patients also remained stable over this time period.

SETTING All histologically confirmed Barrett cases seen over a 3-year period in six MC and 19 CP covering a third of all upper gastrointestinal endoscopies (n = 126,000) performed annually in Berlin, Germany. MAIN OUTCOME MEASURE Rate of relevant neoplasia (high-grade intraepithelial neoplasia or more) in both settings in relation to adherence to standards. RESULTS Of 1317 Barrett cases, 66% were seen in CP. CP patients had a shorter mean Barrett length (2.6 cm vs. 3.8 cm; P < 0.001) with fewer biopsies taken during an examination (2.5 vs. 4.1 for Barrett length <or=2 cm; P < 0.001). CPs also provided fewer complete esophagogastroduodenoscopy documentation (25.1% vs. 57.8%, P < 0.001). Neoplasias were found more commonly in MCs compared to CPs (9.2% vs. 0.8%; P < 0.001). However, on exclusion of all referred patients with known neoplasia (65%) or those examined for other reasons (27.5%), the detection rate at MCs decreased to 1.3%, not different from the one seen at CPs (0.8%, P = 0.43). Only 13% were found during surveillance, but 57% were diagnosed at an early stage. CONCLUSIONS Referral bias and not better adherence to guidelines could explain the higher neoplasia prevalence in Barrett's oesophagus at hospital centres. Despite a generally poor adherence to guidelines, most neoplasias found were at an early and potentially curable stage.

Abstract
The current epidemics of obesity and gastroesophageal reflux disease (GERD)-related disorders have generated much interest in studying the association between them. Results of multiple studies indicate that obesity satisfies several criteria for a causal association with GERD and some of its complications, including a generally consistent association with GERD symptoms, erosive esophagitis, and esophageal adenocarcinoma. An increase in GERD symptoms has been shown to occur in individuals who gain weight but continue to have a body mass index (BMI) in the normal range, contributing to the epidemiological evidence for a possible dose-response relationship between BMI and increasing GERD. Data are less clear on the relationship between Barrett's esophagus (BE) and obesity. However, when considered separately, abdominal obesity seems to explain a considerable part of the association with GERD, including BE. Overall, epidemiological data show that maintaining a normal BMI may reduce the likelihood of developing GERD and its potential complications.

Abstract
Barrett's esophagus is a well-recognized precursor of esophageal adenocarcinoma. Surveillance of Barrett's esophagus patients is recommended to detect high-grade dysplasia (HGD) or early cancer. Because of wide variation in the published cancer incidence in Barrett's esophagus, the authors undertook a systematic review and meta-analysis of cancer and HGD incidence in Barrett's esophagus. Ovid Medline (Ovid Technologies, Inc., New York, New York) and EMBASE (Elsevier, Amsterdam, the Netherlands) databases were searched for papers published between 1950 and 2006 that reported the cancer/HGD risk in Barrett's esophagus. Where possible, early incident cancers/HGD were excluded, as were patients with HGD at baseline. Forty-seven studies were included in the main analysis, and the pooled estimate for cancer incidence in Barrett's esophagus was 6.1/1,000 person-years, 5.3/1,000 person-years when early incident cancers were excluded, and 4.1/1,000 person-years when both early incident cancer and HGD at baseline were excluded. Corresponding figures for combined HGD/cancer incidence were 10.0 person-years, 9.3 person-years, and 9.1/1,000 person-years. Compared with women, men progressed to cancer at twice the rate. Cancer or HGD/cancer incidences were lower when only high-quality studies were analyzed (3.9/1,000 person-years and 7.7/1,000 person-years, respectively). The pooled estimates of cancer and HGD incidence were low, suggesting that the cost-effectiveness of surveillance is questionable unless it can be targeted to those with the highest cancer risk.

Abstract
AIM: To evaluate whether the prevalence of overweight and obese conditions is increased in gastro-esophageal reflux disease (GERD) patients (with 24-h pathological pH recordings) in comparison to general population.
METHODS: A total of 196 consecutive patients (103 females, age range 18-83 years) with symptoms of gastro-esophageal reflux (GER) and 24-h pathological esophageal pH-metry. Body mass index (BMI) of the patients was calculated and its distribution (%) was compared with that of the Italian general population as assessed by National Bureau of Census (ISTAT). To evaluate the association of GERD with weight categories, the binomial test was employed. P < 0.05 was considered statistically significant.
RESULTS: In males, overweightedness (BMI 25-25.9) was present in 43% of GERD patients vs 41.8% of Italian population (IP) (ns), obesity (BMI ≥ 30) in 10.9% vs 9.1% (ns). In females overweight was present in 34.9% of GERD patients vs 25.7% of IP (P < 0.01), obesity in 13.6% of GERD patients vs 9.1% of IP (P < 0.01). No statistically significant differences were noted in different age classes.
CONCLUSION: In comparison to the Italian general population, the prevalence of overweightedness and obesity is increased in female but not in male patients with ascertained gastro-esophageal reflux disease.

Abstract
We aim to determine the expression of the proto-oncogene c-Myc in patients with Barrett's esophagus (BE) and esophageal adenocarcinoma, and to evaluate the prevalence of such expression in relation to the metaplasia-dysplasia-adenocarcinoma sequence. BE develops as a result of a severe esophageal mucosa injury from gastroesophageal reflux. BE is a premalignant lesion and plays an important role in the development of esophageal adenocarcinoma. Several genetic alterations have been identified in the process that transforms a normal cell into a tumorous one. In the development of human tumors, one of the most important genes is the proto-oncogene c-Myc. The c-Myc protein expression was determined by immunohistochemical analysis in four different groups: 31 patients with normal tissue, 43 patients with BE without dysplasia, 11 patients with dysplasia in BE and 37 patients with esophageal adenocarcinoma. The material was obtained from esophageal biopsies or the dissection of patient esophagectomy specimens. Demographic and endoscopic data (sex, age, race and intestinal metaplasia extension), and morphologic and histopathologic tumor characteristics (deep tumor invasion, lymph node status, and tumor differentiation) were analyzed. The c-Myc expression was assessed using the Immunoreactive Scoring System (IRS). Overexpression of c-Myc was found in only 9.6% of normal tissue specimens, 37.2% of Barrett's esophagus, 45.5% of BE patients with dysplasia and 73% of adenocarcinoma samples, with significant statistical difference among these groups. No correlation was identified when the c-Myc expression was compared with morphologic and histologic tumor features or endoscopic data. However, linear correlation of c-Myc overexpression along the metaplasia-dysplasia-adenocarcinoma sequence was observed. This study demonstrates a significant increase in the expression of c-Myc in Barrett's esophagus, dysplasia and adenocarcinoma in relation to the control group, as well as a linear progression of this gene expression in this sequence. These results point out the importance of this marker in the development of esophageal adenocarcinoma from BE.
