Abstract
Gastric polyps (GPs) are increasingly common. On upper endoscopy, they should be examined with white light and occasionally chromoendoscopy, and their morphology classified according to the Paris classification. Most GPs have a typical endoscopic appearance and can be associated with diseases like Helicobacter pylori infection. Histological examination is necessary for an accurate diagnosis. While most polyps are non-neoplastic and do not require treatment, some carry a risk of malignancy or are already malignant. Therefore, understanding the diagnosis, classification, and management of GPs is crucial for patient prognostication. Our new classification categorizes GPs into "good", "bad", and "ugly" based on their likelihood of becoming malignant. We aim to provide descriptions of the endoscopic appearance, pathology, treatment, and follow-up for different GPs, as well as clinical management flowcharts.

Abstract
INTRODUCTION Gastric intestinal metaplasia (GIM) is defined as the replacement of the normal gastric epithelium by intestinal-type epithelium. GIM is considered a preneoplastic lesion for gastric adenocarcinoma in adults and is found in 25% of Helicobacter pylori ( H pylori ) exposed adults. However, the significance of GIM in pediatric gastric biopsies is still unknown. METHODS We conducted a retrospective study of children with GIM on gastric biopsies at Boston Children's Hospital between January 2013 and July 2019. Demographic, clinical, endoscopic, and histologic data were collected and compared to age and sex-matched cohort without GIM. Gastric biopsies were reviewed by the study pathologist. GIM was classified as complete/incomplete based on Paneth cell presence or absence and limited/extensive based on its distribution in the antrum or both antrum and corpus. RESULTS Of 38 patients with GIM, 18 were male (47%), mean age of detection was 12.5 ± 5.05 years (range, 1-18 years). The most common histologic was chronic gastritis (47%). Complete GIM was present in 50% (19/38) and limited GIM was present in 92% (22/24). H pylori was positive in 2 patients. Two patients had persistent GIM on repeat esophagogastroduodenoscopy (2/12). No dysplasia or carcinoma was identified. Proton-pump inhibitor use and chronic gastritis were more common in GIM patients compared to control ( P = 0.02). CONCLUSION Most children with GIM had low-risk histologic subtype (complete/limited) for gastric cancer; GIM was rarely associated with H pylori gastritis in our cohort. Larger multicenter studies are needed to better understand outcomes and risk factors in children with GIM.

Abstract
BACKGROUND/AIMS Little is known about the effect of Helicobacter pylori eradication on the recurrence of gastric hyperplastic polyps after endoscopic resection. Thus, we evaluated the recurrence rate of gastric hyperplastic polyps based on H. pylori eradication following endoscopic resection. METHODS We retrospectively reviewed the medical records of 201 patients with H. pylori infection who underwent endoscopic resection for gastric hyperplastic polyps at six medical centers. H. pylori status was assessed by histological analysis and a rapid urease test. A total of 149 patients underwent successful H. pylori eradication (eradication group), whereas 52 patients had persistent H. pylori infections (non-eradication group). The recurrence rate of gastric hyperplastic polyps and the risk factors according to H. pylori status were analyzed. RESULTS During the mean follow-up period of 18.3 months, recurrent gastric polyps developed after endoscopic resection in 10 patients (19.2% [10/52]) in the non-eradication group and 12 patients (8.1% [12/149]) in the eradication group. The cumulative incidence of recurrent gastric hyperplastic polyps was significantly higher in the non-eradication group than in the eradication group (p = 0.041, log-rank test). In the adjusted analysis, H. pylori eradication reduced the recurrence of gastric hyperplastic polyps (hazard ratio [HR], 0.42; 95% confidence interval [CI], 0.18 to 0.99), whereas anticoagulation therapy increased the risk of recurrence of gastric hyperplastic polyps (HR, 4.91; 95% CI, 1.39 to 17.28). CONCLUSION Successful eradication of H. pylori may reduce the recurrence of gastric hyperplastic polyps in patients after endoscopic mucosal resection.

Abstract
BACKGROUND AND AIMS Familial adenomatous polyposis (FAP) is characterized by high risks of colonic and extracolonic tumors. Recent studies have suggested a rising risk for gastric cancer (GC). We sought to define the spectrum of premalignant gastric polyps in FAP, focusing on high-grade dysplasia (HGD). METHODS The gastric phenotypes of 118 patients diagnosed with FAP or attenuated FAP in our Hereditary Gastrointestinal Cancer Registry were retrospectively reviewed. To analyze the clinical features associated with the diagnosis of HGD, we established an age- and sex-matched control group of FAP patients from our cohort without gastric HGD in a 4:1 ratio. RESULTS The spectrum and frequency of gastric polyps in individuals with FAP included fundic gland polyps (67.9%), hyperplastic polyps/foveolar hyperplasia (19.6%), tubular adenomas (15.2%), foveolar adenomas (10.7%), and pyloric gland adenomas (6.3%). Ten patients (8.9%) exhibited gastric HGD at a mean age of 55 ± 13 years, and HGD was seen in all polyp types. When compared with control subjects, HGD was associated with a high diversity of gastric polyp histology, prior low-grade dysplasia, severe gastric polyposis, and prior Whipple surgery (P = 2.0E-5, .003, .024, and .04, respectively). Two patients (1.7%) with HGD were diagnosed with GC. However, the remaining 8 patients with HGD have been under surveillance for an average of 5.8 ± 4.5 years without progression to GC. CONCLUSIONS Gastric HGD in FAP may be more common than previously appreciated. The natural history of HGD is variable, and most patients with HGD do not appear to progress to GC.

Image-enhanced endoscopy for real-time differentiation between hyperplastic and fundic gland polyps in the stomach. Indian J Gastroenterol 2022; 41:599-609.

Abstract
BACKGROUND Fundic gland polyps (FGP) of stomach are benign, while some hyperplastic polyps (HP) may harbor dysplasia or malignancy. Conventional white light endoscopy (WLE) cannot reliably distinguish FGP from HP. We investigated the role of image-enhanced endoscopy in differentiating FGP from HP. METHODS Patients with gastric polyps were recruited prospectively. The characteristics of the polyps were assessed using WLE and magnification narrow band imaging (mNBI). The microsurface, intervening space (IS), and microvascular (V) features of polyps were evaluated on mNBI. The pattern characteristic of FGP and HP were determined. Histopathology of polyps was the gold standard for diagnosis. Finally, in the validation phase, five endoscopists applied the characteristic features identified in this study to predict the type of gastric polyp and their performance was assessed. RESULTS Forty-five patients with a total of 70 gastric polyps (HP-46, FGP-24) were included in this study. On mNBI, the pattern characteristic of HP included peripheral curved type of white structures forming large circular/villous loops (microsurface), enlarged intervening space, and microvessels appearing as dark patches in the intervening space (p<0.001 vs. FGP). These were noted in 95.7% HP. In contrast, 95.8% FGP had a pattern characterized by dotted/elliptical/tubular white structures (microsurface), normal width of intervening space, and microvessels surrounding the white structures in a network pattern. This IS-V pattern classification had an accuracy of >90% in the validation phase with intra-class correlation coefficient of 0.95. The accuracy of mNBI was higher than WLE (97.1% vs. 67%) in predicting the type of gastric polyp. CONCLUSIONS Image-enhanced endoscopy with mNBI (IS-V pattern) performs very well in differentiating HP from FGP.

Abstract
Gastric cancer (GC) has a good prognosis, if detected at an early stage. The intestinal subtype of GC follows a stepwise progression to carcinoma, which is treatable with early detection and intervention using high-quality endoscopy. Premalignant lesions and gastric epithelial polyps are commonly encountered in clinical practice. Surveillance of patients with premalignant gastric lesions may aid in early diagnosis of GC, and thus improve chances of survival. An expert professional workgroup was formed to summarise the current evidence and provide recommendations on the management of patients with gastric premalignant lesions in Singapore. Twenty-five recommendations were made to address screening and surveillance, strategies for detection and management of gastric premalignant lesions, management of gastric epithelial polyps, and pathological reporting of gastric premalignant lesions.

Abstract
Giant gastric hyperplastic polyps are the most common benign epithelial tumors in the stomach. These are non-neoplastic epithelial proliferations of the stomach which are strongly associated with inflammatory conditions like chronic gastritis, helicobacter pylori gastritis, reactive or chemical gastritis. A 60 years old gentleman presented with history of two bouts of hematemesis preceded by multiple intermittent episodes of epigastric pain, nausea and few episodes of non-bilious vomiting without any history of previous gastrointestinal bleed, loss of appetite or significant weight loss. Work up with ultrasonography of abdomen, upper gastrointestinal endoscopy, contrast enhanced computed tomography abdomen, laboratory investigations followed by biopsy and histopathology was done which confirmed the diagnosis. Giant hyperplastic polyps are benign epithelial tumor of stomach often resulting from excessive regenerative hyperplasia in areas of chronic inflammation with no site predilection and nearly no malignant potential. Usually asymptomatic, these are incidentally detected on upper gastrointestinal endoscopy with characteristic appearance of such polyps on double contrast barium study followed by upper gastrointestinal endoscopy and biopsy is definitive for diagnosis.

Abstract
Gastric hyperplastic polyps (GHP) are frequently found to be benign polyps and have been considered to have a low carcinogenic potential. The characteristics of the hyperplastic polyp-associated gastric cancer (HPAGC) remain unclear. Therefore, we analyzed samples from 102 GHP patients and identified 20 low-grade atypical GHPs (19.6%), 7 high-grade atypical GHPs (6.9%), and 5 intramucosal cancer samples (4.9%). GHP atypia was more common in the elderly and increased with increasing polyp size. In particular, polyps larger than 1 cm were associated with a higher grade and cancer. Furthermore, mucus production decreased with increasing atypia. Although no correlation was found between atypia and Helicobacter pylori infection or intestinal metaplasia, enhanced proliferative ability (Ki-67) did correlate with atypia, as did nuclear 8-hydroxy-2'-deoxyguanosine levels. Interestingly, 4-hydroxynonenal levels in granulation tissue and the area ratio of granulation tissue within polyps also correlated with GHP atypia. In five cases of HPAGC, three cases exhibited caudal type homeobox transcription factor (CDX2)-positive cells and a mixed mucin phenotype, which is considered to be related to H. pylori infection. By contrast, two cases were CDX2 negative, with a gastric mucin phenotype, and H. pylori infection was not observed in the tumor or the surrounding mucosa. In these cases, a v-raf murine sarcoma viral oncogene homolog B1 (BRAF) mutation (V600E) was detected. All cancer samples showed high stemness and p53 protein accumulation, but no KRAS mutations. The molecular and phenotypic characteristics of the cases characterized by BRAF mutations may represent a novel subtype of HPAGC, reflecting a conserved pathway to oncogenesis that does not involve H. pylori infection. These findings are worthy of further investigation in a large-scale study with a substantial cohort of HPAGC patients to establish their clinical significance.

Abstract
Introduction Hyperplastic polyps represent 30-93% of all gastric epithelial polyps. They are generally detected as innocuous incidental findings; however, they have a risk of neoplastic transformation and recurrence. Frequency and risk factors for neoplastic transformation and recurrence are not well established and are fields of ongoing interest. This study aims to evaluate the frequency of and identify the risk factors for recurrence and neoplastic change of gastric hyperplastic polyps (GHP). Methods A single-centre retrospective cohort study including consecutive patients who underwent endoscopic resection of GHP from January 2009 to June 2020. Demographic, endoscopic, and histopathologic data was retrieved from the electronic medical records. Results A total of 195 patients were included (56% women; median age 67 [35-87] years). The median size of GHP was 10 (3-50) mm, 62% (n = 120) were sessile, 61% (n = 119) were located in the antrum, and 36% (n = 71) had synchronous lesions. Recurrence rate after endoscopic resection was 23% (n = 26). In multivariate analysis, antrum location was the only risk factor for recurrence (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.1-8.1). Overall, 5.1% (n = 10) GHP showed neoplastic transformation, with low-grade dysplasia in 5, high-grade dysplasia in 4, and adenocarcinoma in 1. In multivariate analysis, a size >25 mm (OR 84; 95% CI 7.4-954) and the presence of intestinal metaplasia (OR 7.6; 95% CI 1.0-55) and dysplasia (OR 86; 95% CI 10-741) in adjacent mucosa were associated with an increased risk of neoplastic transformation. Recurrence was not associated with neoplastic transformation (OR 1.1; 95% CI 0.2-5.9). Discussion Our results confirmed the risk of recurrence and neoplastic transformation of GHP. Antrum location was a predictor of recurrence. The risk of neoplastic change was increased in large lesions and with intestinal metaplasia and dysplasia in adjacent mucosa. More frequent endoscopic surveillance may be required in these subgroups of GHP.

Abstract
Gastrointestinal endoscopy is the primary method used for the diagnosis and treatment of gastric polyps. The early detection and removal of polyps is vitally important in preventing cancer development. Many studies indicate that a high workload can contribute to misdiagnosing gastric polyps, even for experienced physicians. In this study, we aimed to establish a deep learning-based computer-aided diagnosis system for automatic gastric polyp detection. A private gastric polyp dataset was generated for this purpose consisting of 2195 endoscopic images and 3031 polyp labels. Retrospective gastrointestinal endoscopy data from the Karadeniz Technical University, Farabi Hospital, were used in the study. YOLOv4, CenterNet, EfficientNet, Cross Stage ResNext50-SPP, YOLOv3, YOLOv3-SPP, Single Shot Detection, and Faster Regional CNN deep learning models were implemented and assessed to determine the most efficient model for precancerous gastric polyp detection. The dataset was split 70% and 30% for training and testing all the implemented models. YOLOv4 was determined to be the most accurate model, with an 87.95% mean average precision. We also evaluated all the deep learning models using a public gastric polyp dataset as the test data. The results show that YOLOv4 has significant potential applicability in detecting gastric polyps and can be used effectively in gastrointestinal CAD systems.

Abstract
The liberal use of upper endoscopy has led to an increased detection of gastric and duodenal polyps, which are identified in as many as 6 and 4.6% of patient examinations, respectively. Gastroduodenal polyps are a heterogeneous group of lesions that can be neoplastic or non-neoplastic (e.g. hyperplastic or heterotopical). Most polyps present characteristic topographical features, as well as endoscopic appearance and size. Evaluation of the surrounding mucosa is essential in assessing the underlying pathology (e.g. Helicobacter pylori, autoimmune gastritis or inherited polyposis syndromes). Phylogenetically, gastric and duodenal polyps can be classified according to the epithelial compartment from which they derive. Polyps that arise from the surface epithelium can either be of foveolar or intestinal type, and they can develop from either the native mucosa or the metaplastic epithelium (gastric intestinal metaplasia or duodenal foveolar metaplasia). Other polyps develop from the deeper glandular component, such as pyloric/oxyntic gland derived subtypes. In this review we focus upon epithelial polyps, with an emphasis on the most common and clinically relevant lesions, and present recently described entities.

Abstract
Background The association of upper gastrointestinal endoscopic findings with sex, age, and Helicobacter pylori infection in asymptomatic healthy people is unclear. The aim of this study was to retrospectively determine the associations of upper gastrointestinal endoscopic findings in asymptomatic healthy people with sex, age, and H. pylori infection.
Methods A retrospective study was conducted on 2923 patients from a health examination center in Xiangya Hospital between September 2015 and September 2019. Data on sex, age, H. pylori infection, and gastroscopy results were collected.
Results Among 2923 asymptomatic patients who underwent gastroscopy, 2911 (99.59%) had abnormal results. The top three results were chronic gastritis (95.11%), peptic ulcer (17.45%), and duodenitis (9.17%). Inflammation of the gastric mucosa in chronic gastritis was more severe in the H. pylori-positive group. The incidence of peptic ulcer decreased with increasing age and was higher in men, patients aged < 30 years, and H. pylori-positive patients. The incidence of polyps was higher in women (9.54%) than in men (5.94%), and the incidence in individuals aged ≥60 years (11.63%) was higher than that in those aged < 60 years (6.83%). The pathological results of gastric polyps depended on the location of the lesion. Conclusion The incidence of abnormal upper gastrointestinal endoscopic results is high in asymptomatic healthy people undergoing a check-up and is associated with sex, age, and H. pylori infection. Gastroscopy should be considered part of a routine health check.

Polypoid lesions detected in the upper gastrointestinal endoscopy: A retrospective analysis in 19560 patients, a single-center study of a 5-year experience in Turkey. North Clin Istanb 2020; 8:178-185. [PMID: 33851083 PMCID: PMC8039112 DOI: 10.14744/nci.2020.16779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 09/10/2020] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVE: In our study, we aimed to evaluate the endoscopic features such as prevalence and localization of polypoid lesions determined by us using esophagogastroduodenoscopy and histopathological characteristics of biopsy specimens taken in detail. METHODS: The data of 19,560 patients undergoing upper gastrointestinal endoscopy for any reason between 2009 and 2015 in our endoscopy unit were screened retrospectively and endoscopic and histopathological findings were analyzed in detail. RESULTS: In our study, the polypoid lesion was detected in 1.60% (n=313) of 19,560 patients. The most common localization of the polypoid lesions was determined to be gastric localization (n=301, 96.2%) and antrum with a rate of 33.5% (n=105). When 272 patients in whom biopsy specimen could be taken was investigated, the most frequently seen lesion was polyp (n=115, 43.4%). Hyperplastic polyps (n=81, 29.8%) were the most frequently seen type among all polyps. In histopathological evaluation of the lesions, the prevalence rates of intestinal metaplasia (IM), surrounding tissue IM, atrophy, dysplasia, and neoplasia (adenocarcinoma, squamous cell carcinoma, gastrointestinal stromal tumor, neuroendocrine tumor, and metastatic tumor) among premalignant lesions were determined to be 16.9%, 11.2%, 4.1%, 1.1%, and 3.7%, respectively. CONCLUSION: Polypoid lesions can be seen in endoscopic investigations. In histopathological investigations, while the vast majority of these lesions are benign polyps, some of them are diagnosed as premalignant or malignant lesions. In our study, we determined malignant lesions higher than the similar studies in the literature. This condition shows how effective endoscopic procedure and histopathological evaluation are of vital importance.

Abstract
Objectives With the widespread use of esophagogastroduodenoscopy (EGD) in recent years, upper gastrointestinal system polyps have started to be encountered more often. Although most patients with gastric polyps are asymptomatic, these are important due to their malign potential, and gastric cancer may develop if left untreated. Material and Methods Records of 12.563 patients who underwent EGD at Kartal Kosuyolu High Specialization Health Application and Research Center for any reason between January 2013 and June 2016 were reviewed retrospectively. Patients with at least 1 histopathologically proven polyp were included in this study. Results A total of 12.563 endoscopic procedures of the upper gastrointestinal system were investigated and 353 (2.8%) polypoid lesions were detected. Mean age of these patients was 56.3 years and 241 (68.3%) of the patients were female. Gastric polyps were found most commonly in the antrum (50.1%) and of all gastric polyps, 245 (69.5%) were less than 1 cm. Histopathological evaluation showed that hyperplastic polyp (HP) (n= 151, 42.8%) was the most common polyp type, followed by fundic gastric polyp (FGP) (n= 51, 14.4%). Non-polyp gastric mucosa evaluation of 298 patients revealed that 34.9% of the cases were Helicobacter pylori positive, 19.4% had intestinal metaplasia, and 11.4% had atrophic gastritis. Conclusion Polyps of the upper gastrointestinal system are generally detected coincidentally as they have no specific symptoms. Polypectomy is required for gastric polyps because of their potential for malign transformation according to medical evidence.

Risk factors and clinical correlates of neoplastic transformation in gastric hyperplastic polyps in Chinese patients. Sci Rep 2020; 10:2582.

Abstract
Gastric hyperplastic polyps (GHPs) have a potential risk of neoplastic transformation, but the responsible mechanisms have not yet been established. We conducted a study involving 55 patients (33 female) who had undergone endoscopic or surgical resection of GHPs. We compared 16 patients who had GHPs showing neoplastic transformation with 39 patients who had non-neoplastic GHPs. We analyzed differences in serology, gastroscopic manifestations and pathology between the two groups in order to establish risk factors that may be associated with neoplastic transformation. The mean age of the cohort was 61.73 ± 9.024 years. The prevalence of positive serum gastric parietal cell antibody (PCA) was 61.8%. 30 of the GHPs with neoplastic formation had a “strawberry-like” appearance with erosions of polyps (P = 0.000). A history of anaemia was a risk factor for GHPs which demonstrated neoplastic transformation (odds ratio [OR], 3.729; 95% confidence interval [CI], 1.099–12.649; P = 0.035). Although the differences were not significant, our data showed higher prevalences of positive serum PCA (P = 0.057), hypergastrinemia (P = 0.062) and female gender (P = 0.146) in the GHP patients who had neoplastic transformation. Multiple polyps in the corpus (P = 0.024) occurred more frequently in serum PCA positive patients. Hypergastrinemia occurred more frequently in Helicobacter pylori negative patients and of these 20/22 patients had a positive PCA (P = 0.007). GHPs are associated with autoimmune metaplastic atrophic gastritis (AMAG). AMAG is probably one of the risk factors for GHPs to undergo neoplastic transformation.

Abstract
Background/Aims Fundic gland polyps (FGPs), hyperplastic polyps (HPs), and xanthomas (XTs) are common benign gastric lesions that can be diagnosed by endoscopic appearance alone in most cases. The aim of this study was to evaluate associations between gastric cancer and these benign lesions. Methods Two expert endoscopists reviewed a series of gastroscopy images. FGPs, HPs, and XTs were diagnosed by endoscopic appearance, whereas all gastric cancers were confirmed pathologically. Results Of the 1,227 patients reviewed, 114 (9.3%) had a concurrent or past history of gastric cancer. The overall prevalences of FGPs, HPs and XTs were 9.4%, 6.3% and 14.2%, respectively. HPs and XTs coexisted in 1.6% of patients, whereas other combinations were rarer. XTs were observed in 39.3% and 11.5% of patients with and without gastric cancer, respectively (p<0.001). In contrast, no gastric cancer patients had FGPs, whereas 10.4% of patients without cancer had FGPs (p<0.001). The prevalence of HPs was similar between the two groups (8.8% and 6.0% of patients with and without cancer, respectively, p=0.29). Multivariate and Mantel-Haenszel analyses demonstrated that XTs were positively associated and FGPs were negatively associated with gastric cancer. Conclusions XTs and FGPs might be useful as endoscopic risk indicators for monitoring gastric cancer.

Abstract
Gastric adenocarcinoma carries a poor prognosis, in part due to the late stage of diagnosis. Risk factors include Helicobacter pylori infection, family history of gastric cancer-in particular, hereditary diffuse gastric cancer and pernicious anaemia. The stages in the progression to cancer include chronic gastritis, gastric atrophy (GA), gastric intestinal metaplasia (GIM) and dysplasia. The key to early detection of cancer and improved survival is to non-invasively identify those at risk before endoscopy. However, although biomarkers may help in the detection of patients with chronic atrophic gastritis, there is insufficient evidence to support their use for population screening. High-quality endoscopy with full mucosal visualisation is an important part of improving early detection. Image-enhanced endoscopy combined with biopsy sampling for histopathology is the best approach to detect and accurately risk-stratify GA and GIM. Biopsies following the Sydney protocol from the antrum, incisura, lesser and greater curvature allow both diagnostic confirmation and risk stratification for progression to cancer. Ideally biopsies should be directed to areas of GA or GIM visualised by high-quality endoscopy. There is insufficient evidence to support screening in a low-risk population (undergoing routine diagnostic oesophagogastroduodenoscopy) such as the UK, but endoscopic surveillance every 3 years should be offered to patients with extensive GA or GIM. Endoscopic mucosal resection or endoscopic submucosal dissection of visible gastric dysplasia and early cancer has been shown to be efficacious with a high success rate and low rate of recurrence, providing that specific quality criteria are met.

Abstract
Background To determine the risk factors and prevalence of asymptomatic gastric polyps in the general population of Taiwan. Methods Consecutive asymptomatic individuals completing a health examination during October 2015–March 2016 were enrolled in the study and subjected to upper GI endoscopy. Their demographic data and medical history were collected, and the prevalence of gastric polyps was calculated. The risk factors of gastric polyps were identified by analyzing these data through univariate and multivariate logistic regression. Results Gastric polyp prevalence in the study population was 29.8%. Age range of 45–60 years, current smoking, and lack of regular exercise were found to be significantly associated with gastric polyps, whereas age range of 45–60 years (relative risk [RR], 1.59; 95% confidence interval [CI], 1.06–2.40) and current smoking (RR, 1.63; 95% CI, 1.04–2.55) were found to be independent predictors for gastric polyps. Conclusions In Taiwan, asymptomatic gastric polyps have a prevalence of 29.8%. Age range of 45–60 years and current smoking may increase the risk of asymptomatic gastric polyps.

Abstract
OBJECTIVE Recent guidelines on endoscopic sampling recommend complete gastric polyp removal for solitary fundic polyps >10 mm, hyperplastic polyps >5 mm and all adenomatous polyps. We aim to describe endoscopic approach to polyps in the time period prior to the American Society of Gastrointestinal Endoscopy (ASGE) guidelines and to identify opportunities for clinical practice improvements. DESIGN Retrospective review of the Clinical Outcome Research Initiative (CORI) database, including all oesophagogastroduodenoscopies (OGDs). Reviewers grouped interventions during procedures based on instruments used for polyp sampling by forceps or snare polypectomy. Logistic regression estimated the effect of variables of interest on method of polypectomy. RESULTS Of 783 037 OGDs reported in the CORI database, 25 670 (3.3%) described gastric polyps and met the inclusion criteria. Mean gastric polyp size was 6.5±4.9 mm, and 46.2% and 14.5% were located in the corpus and antrum, respectively. Polyps in the forceps group were smaller than polyps in the snare group (5.7±4.0 mm vs 9.3±6.4 mm, respectively, p<0.001). We identified 1056 polyps (41.3%) >10 mm that only underwent forceps biopsy. Forceps were used more frequently in the gastric fundus. CONCLUSIONS Snare polypectomy was underused in gastric polyps, per current ASGE guidelines. Anatomical location and endoscopic features of polyps were important predictors of the approach to gastric polypectomy.

Abstract
Hyperplastic polyps are the most frequent benign epithelial gastric polyps. Although they are considered nonneoplastic, some cases have been reported with focal adenocarcinoma. We present the case of a 59-year-old woman with a sessile lesion of 15 mm on the distal gastric body associated with an extensive atrophic gastritis. Magnifying endoscopy with Fuji Intelligent Color Enhancement (FICE) revealed an irregular microsurface pattern at the apex, suggesting malignancy. A mucosectomy was performed. The histopathology revealed that the base corresponded to a hyperplastic polyp, where a tubular adenoma with high-grade dysplasia was established, with focal well-differentiated intramucosal tubular adenocarcinoma.

Abstract
Most solitary gastrointestinal (GI) polyps in children are either inflammatory or hamartomatous. Solitary hyperplastic polyp, sentinel polyp and solitary adenomatous polyp have been occasionally diagnosed in adults, but very rarely reported in Korean children. We recently came across a case with adenomatous polyp in the colon, a case with hyperplastic polyp beneath the gastroesophageal junction, a case with hyperplastic polyp in the prepyloric area, and a case with sentinel polyp in the distal esophagus, which are unusual pathologic types in children. These mucosal lesions were diagnosed incidentally during elective endoscopic examinations for GI symptoms. Most polyps do not cause significant symptoms, so the diagnosis might be delayed, especially in children, in whom GI endoscopy is not commonly performed for screening purpose as in the adults.

Abstract
Early gastric cancer (ECG) can be difficult to diagnose endoscopically. Endoscopists should be familiar with subtle changes and endoscopic features of EGC. Chromoendoscopy and image-enhanced endoscopy improve diagnostic accuracy and facilitate endoscopic resection. Endoscopic submucosal dissection is a preferred endoscopic technique for resection of EGC and offers a comparable overall survival to surgical resection. Endoscopic management of benign gastric epithelial polyps (fundic gland polyps, hyperplastic polyps, and gastric adenoma) depends on patient symptomatology, patient's comorbidities (eg, familial syndromes), lesions' characteristics, and risk of malignant transformation. This article provides an overview of endoscopic management of EGC and common premalignant gastric lesions.

Abstract
Gastric polyps are frequently reported in patients undergoing upper endoscopic procedures. In this retrospective study, the association between hyperplastic polyps and celiac disease in Northern Sardinia was estimated.Age, gender, body mass index, and medications taken in the 2 preceding months, including proton-pump inhibitors (PPIs), H2 receptor blockers (anti-H2), Helicobacter pylori status, endoscopic findings, and histology from charts of patients undergoing esophago-gastro-duodenoscopy were reviewed. Polyps were classified as hyperplastic, fundic gland, inflammatory, and adenomatous.3.7% (423/11379) patients had celiac disease. Prevalence of gastric polyps was 4.2% (3.8% among celiac vs 4.2% nonceliac patients). Inflammatory polyp was the most common histotype (55.8% and 56.2%) followed by fundic gland polyps (31.4% and 43.7%), hyperplastic (8.7% and 0%), and adenomas, in celiac and nonceliac patients, respectively. Fundic gland polyps were more common in PPI users (odds ratio: 4.06) than in nonusers (2.65, P = 0.001) among celiac and nonceliac patients. Age older than 50, female gender, esophago-gastro-duodenoscopy year, and PPI use were associated with the presence of polyps, whereas active H pylori infection was not.Gastric polyps were common in Sardinian patients undergoing esophago-gastro-duodenoscopy. However, the previously reported association between hyperplastic polyps and celiac disease was not confirmed in our study.

Abstract
Hyperplastic polyps of the stomach are routinely encountered during upper endoscopy and often arise in the setting of abnormal surrounding mucosa, particularly Helicobacter pylori, autoimmune gastritis, and reactive gastropathy. Not infrequently gastroenterologists fail to biopsy the surrounding mucosa, thus determining the underlying etiology of the gastric hyperplastic polyp can be difficult. Recently, the Rodger C. Haggitt Gastrointestinal Pathology Society published guidelines on the use of special stains. The society guidelines indicate that H pylori are not usually present in hyperplastic polyps and special stains in this setting may have limited utility. We analyzed the histologic features of 32 gastric hyperplastic polyps in which the nonpolypoid mucosa demonstrated H pylori gastritis. A consecutive series of 50 hyperplastic polyps in which no surrounding mucosa was sampled was also analyzed. When H pylori are identified in biopsies of the nonpolypoid mucosa, it is also commonly present within the polyp tissue (22/32, 69%). The majority of H pylori organisms were identified on routine hematoxylin and eosin stain (16/22, 72%). In contrast, H pylori were only seen in 2/50 consecutive hyperplastic polyps in which the surrounding mucosa was not sampled. Compared with the hyperplastic polyps that lack the organisms, H pylori associated hyperplastic polyps more commonly had dense lymphoplasmacytic inflammation (P = .0001) and neutrophils within gastric epithelium (P = .036). Polyp location, number, size, and presence of intestinal metaplasia was not associated with H pylori These results provide empirical data to guide evaluation of hyperplastic polyps for H pylori.

Abstract
Gastric hyperplastic polyps are generally considered benign lesions, although rare cases of adenocarcinoma have been reported. Two cases of intramucosal adenocarcinoma originating from gastric hyperplastic polyps that were successfully removed by endoscopic mucosal resection or endoscopic submucosal dissection are reported. On pathological examination, adenocarcinoma limited to the hyperplastic foveolar epithelial mucosa of the gastric hyperplastic polyps was observed.

Abstract
AIM: To assess the endoscopic characteristics of gastric polyps and their association with Helicobacter pylori (H. pylori) status in a predominantly Hispanic population.
METHODS: We conducted a retrospective study of all esophagogastroduodenoscopies performed at our institution. Demographic, endoscopic and histopathological data were reviewed. Categorization of patients into Hispanic and Non-Hispanic was based on self-identification. Patients without resection/biopsy were not included in the analysis. Identification of polyps type was based on histological examination. One way analysis of variance was used to compare continuous variables among different polyp types and Fisher’s exact test was used compare categorical variables among polyp types. Unadjusted and adjusted comparisons of demographic and clinical characteristics were performed according to the H. pylori status and polyp type using logistic regressions.
RESULTS: Of 7090 patients who had upper endoscopy, 335 patients had gastric polyps (4.7%). Resection or biopsy of gastric polyps was performed in 296 patients (88.4%) with a total of 442 polyps removed or biopsied. Of 296 patients, 87 (29%) had hyperplastic polyps, 82 (28%) had fundic gland polyps and 5 (1.7%) had adenomatous polyps. Hyperplastic polyps were significantly associated with positive H. pylori status compared with fundic gland polyps (OR = 4.621; 95%CI: 1.92-11.13, P = 0.001). Hyperplastic polyps were also found to be significantly associated with portal hypertensive gastropathy compared with fundic gland polyps (OR = 6.903; 95%CI: 1.41-33.93, P = 0.0174). Out of 296 patients, 30 (10.1%) had a follow-up endoscopy with a mean duration of 26 ± 16.3 mo. Interval development of cancer was not noted in any of the patients during follow up period.
CONCLUSION: Gastric hyperplastic polyps were significantly associated with positive H. pylori status and portal hypertensive gastropathy as compared with fundic gland polyps.

Abstract
AIMS The aim of the study was to utilize a large national histopathology database for the analysis of the clinical epidemiology of gastric polyps. METHODS In a case-control study, 71,575 case subjects with gastric polyps were compared to 741,351 control subjects without gastric polyps. RESULTS Of all patients, 7.72% harboured fundic gland polyps, 1.79% gastric hyperplastic polyps, 0.09% gastric adenomas, and 0.06% type I neuroendocrine tumours. All types showed a clear-cut age-dependent rise. Reflux disease was significantly more common in patients with fundic gland polyps and significantly less common in patients with gastric adenomas or neuroendocrine tumours. Anaemia was more common in patients with gastric hyperplastic polyps, gastric adenomas, or neuroendocrine tumours. Helicobacter pylori was found significantly less frequently in all subjects with gastric polyps than in controls. Intestinal metaplasia and gastric atrophy were both more common in gastric adenoma and neuroendocrine tumours and less common in fundic gland polyps than in controls. Different polyp types tended to coincide in the same patients. CONCLUSIONS Gastric hyperplastic polyps appeared to mark the beginning of a progression from chronic gastritis to intestinal metaplasia and gastric atrophy, which leads to diminished gastric acid output and increased gastrin secretion. Gastric adenoma and neuroendocrine tumours reflect later stages of this process.

Abstract
BACKGROUND Little is known about gastric neoplasms arising from hyperplastic polyps (HPs). OBJECTIVE To investigate the risk factors associated with neoplasms within HPs and to evaluate the role of alterations of the p16-cyclin D1-pRb pathway in the malignant transformation of HPs. DESIGN Retrospective, case-control study. SETTING Tertiary-care center. PATIENTS Between May 1995 and January 2011, a total of 809 HPs >1 cm were investigated. Associated neoplasms were present in 30 HPs (case group); 30 HPs without neoplasms were selected as a control group. INTERVENTIONS Gastric polypectomy. MAIN OUTCOME MEASUREMENTS The risk factors associated with neoplasms within HPs and immunohistochemical expression of p16, cyclin D1, p53, and Ki-67 between case and control groups. RESULTS Of the 809 HPs, 15 had associated dysplasia, and 15 had carcinoma. Multivariate analysis showed that neoplasm was associated with patient age (odds ratio [OR] 1.159; 95% confidence interval [CI], 1.243-2.044; P < .001), polyp size (OR 1.103; 95% CI, 1.055-1.152; P < .001), and polyp lobulation (OR 4.549; 95% CI, 1.759-11.0766; P < .001) but not with location, multiplicity, intestinal metaplasia, growth pattern, or Helicobacter pylori infection. Loss of p16 expression and high Ki-67 expression were observed in dysplastic areas of HPs compared with the control group (p16 = 14.3% vs 60%; P = .001, Ki-67 = 60.7% vs 36.7%; P < .001). However, no significant differences were found in nondysplastic areas in both groups. LIMITATIONS Single-center, retrospective study. CONCLUSION HPs >1 cm may indicate the presence of neoplasms. Loss of p16 and high Ki-67 expression may be markers of HP-associated dysplasia.

Abstract
AIM: To compare the clinical and pathological features of gastrointestinal polyps between Han people and nomadic people in Tacheng, Xinjiang, and to summarize the features of gastrointestinal polyps in nomadic people.
METHODS: A retrospective analysis of Han people and nomadic people who underwent gastroscopy (n = 7538) or enteroscopy (n = 657) at the City Hospital of Tacheng and the Region Hospital of Tacheng from January 1, 2012 to December 31, 2013 was performed. The numbers and pathology results of gastric polyps and intestinal polyps were analyzed.
RESULTS: Among the gastrointestinal polyp patients in Tacheng, the baseline data such as gender composition and age were similar between the two groups. The detection rates of gastric hyperplastic polyps (15.09% vs 19.91%, P > 0.05) and gastric inflammatory polyps (10.38% vs 11.85%, P > 0.05) between the nomadic people and Han people showed no statistical difference. The detection rate of gastric adenomatous polyp in nomadic people was significantly higher than that in Han people (54.72% vs 8.53%, P < 0.05), while that of fundic gland polyps was lower (19.81% vs 59.71%, P < 0.05). The detection rate of intestinal inflammatory polyps between the two groups showed no statistical difference (8.00% vs 11.65%, P > 0.05). The detection rate of intestinal adenomatous polyps in nomadic people was higher than that in Han people (80.00% vs 60.19%, P < 0.05), while that of intestinal hyperplastic polyps was lower (12.00% vs 28.16%, P < 0.05).
CONCLUSION: Because of the differences in diets and living habits between nomadic people and Han people, the detection rates of digestive adenomatous polyps in nomadic people are higher than those in Han ethnic group, while the detection rate of fundic gland polyps is lower. Since adenomatous polyps may undergo malignant transformation, regular follow-up by endoscopy and colonoscopy is recommended for nomadic people.

Abstract
The endoscopic finding of a gastric polyp and the histopathologic report that follows may leave clinicians with questions that have not been addressed in formal guidelines: do all polyps need to be excised, or can they just be sampled for biopsy? If so, which ones and how many should be sampled? What follow-up evaluation is needed, if any? This review relies on the existing literature and our collective experience to provide practical answers to these questions. Fundic gland polyps, now the most frequent gastric polyps in Western countries because of widespread use of proton pump inhibitors, and hyperplastic polyps, the second most common polyps notable for their association with gastritis and their low but important potential for harboring dysplastic or neoplastic foci, are discussed in greater detail. Adenomas have had their name changed to raised intraepithelial neoplasia and are decreasing in parallel with Helicobacter pylori infection; however, they do retain their importance as harbingers of gastric cancer, particularly in East Asia. Gastrointestinal stromal tumors have low incidence and no known associations, but their malignant potential is high; early diagnosis and proper management are crucial. Although rare and benign, inflammatory fibroid polyps need to recognized, particularly by pathologists, to avoid misdiagnosis. Gastric neuroendocrine tumors (carcinoids) are important because of their association with either atrophic gastritis or the multiple endocrine neoplasia syndromes; those that do not arise in these backgrounds have high malignant potential and require aggressive management. The review concludes with some practical suggestions on how to approach gastric polyps detected at endoscopy.

Abstract
BACKGROUND The prevalence of gastric polyps is unknown in Hungary. AIM The aim of the authors was to assess the prevalence of polypoid lesions of the stomach in the endoscopic centre of the 2nd Department of Medicine, Semmelweis University. METHODS Results of upper gastrointestinal endoscopies carried out between March 2010 and June 2011 were analysed. RESULTS 193 cases with polyps were diagnosed in 4174 endoscopies (4.62%). Hyperplastic polyps, fundic gland polyps and malignant lesion were detected in 33.67%, 31.09% and 2.07% of the cases, respectively. Proton pump inhibitor use was more frequent among patients diagnosed with fundus gland polyps (p = 0.007), while hyperplastic polyps were diagnosed more frequently in patients with chronic gastritis (p = 0.032). CONCLUSIONS The frequency of gastric polyps was higher than expected from data published in the literature. Long-term proton pump-inhibitor use and chronic gastritis were associated with fundus gland and hyperplastic polyps, respectively.

Gastric cancer is the final step in a multi-stage cascade triggered by long-standing inflammatory conditions (particularly Helicobacter pylori infection) resulting in atrophic gastritis and intestinal metaplasia: these lesions represent the cancerization field in which (intestinal-type) gastric cancer develops. Intraepithelial neoplasia is consistently recognized as the phenotypic bridge between atrophic/metaplastic lesions and invasive cancer. This paper addresses the epidemiology, pathology, molecular profiling, and clinical management of advanced precancerous gastric lesions.

Abstract
Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric polyps presenting as acute gastrointestinal bleeding in the medical literature. We present a case of a 56-year-old African American woman who was admitted to our hospital with symptomatic anemia and sepsis. The patient developed acute upper gastrointestinal bleeding during her hospital stay. She underwent emergent endoscopy, but bleeding could not be controlled. She underwent emergent laparotomy and wedge resection to control the bleeding. Biopsy of surgical specimen was reported as hyperplastic gastric polyp. We recommend that physicians should be aware of this rare serious complication of hyperplastic gastric polyps as endoscopic polypectomy has diagnostic and therapeutic benefits in preventing future complications including bleeding.

Abstract
BACKGROUND AND AIM Traditionally the most common gastric polyps are hyperplastic polyps (HPs). However, in the last two decades, fundic gland polyps (FGPs) have greatly increased in Western countries. We aimed to re-evaluate and compare the distribution of gastric polyps in a northern Chinese population in 2000 and 2010. METHODS Consecutive patients with gastric polyps detected in 2000 and 2010 were analyzed and biopsies were re-evaluated. Data including patients' age, sex, symptoms and the number, size, location, Helicobacter pylori (H. pylori) infection of polyps were recorded. RESULTS A total of 6784 and 17 337 patients underwent esophagogastroduodenoscopy in 2000 and 2010, 68 and 183 patients were diagnosed with gastric polyps, respectively. H. pylori infection decreased from 54.4% to 37.7% (P = 0.017). Overall, spectrum of gastric polyps changed (P < 0.001). HPs accounted for 28.3% and decreased from 48.5% to 20.8%, adenoma/carcinoma and inflammatory polyps also decreased. FGPs were present in 50.6% and increased from 8.8% to 66.1%. The location of polyps was also changed with an increase of polyps in gastric corpus. There was a high proportion of FGPs in females, while adenomas/adenocarcinomas were more common in males. The distribution pattern was similar in young and elderly patients. CONCLUSIONS Spectrum change of gastric polyps was observed over the past 10 years in the northern Chinese population most likely due to the higher proportion of FGPs. Further studies are required to investigate the reasons and confirm whether it will lead to a different management strategy in China.

Abstract
BACKGROUND/AIMS Hyperplastic polyps (HPs) are the most common cause of all benign epithelial gastric polyps, constituting 30 to 93%. Although gastric HPs are usually considered as benign lesions compared with adenoma, neoplastic transformation has been known to occur rarely. We aimed to identify the clinical factors of gastric HPs predicting for neoplastic transformation. METHODS Between January 2002 to August 2010, a total of 274 gastric HPs, which had been removed by endoscopic polypectomy or surgical resection from 210 patients, were analyzed retrospectively. RESULTS Neoplastic transformation was found in 15 cases (5.5%) of 274 HPs including 10 cases of low grade dysplasia (3.7%), 2 cases of high grade dysplasia (0.7%) and 3 cases of adenocarcinoma (1.1%). Neoplastic transformations were significantly associated with >1 cm in size (n=10 [66.7%] vs. n=91 [35.1%], p=0.024), with pedunculated shape (n=9 [60.0%] vs. n=62 [23.9%], p=0.002), with previous history of gastrectomy (n=3 [20.0%] vs. n=3 [1.2%], p=0.002) and with synchronous neoplastic lesions occurring elsewhere in the gastric mucosa (n=5 [33.3%] vs. n=31 [12.0%], p=0.021). However, no significant difference was found between HPs with and without neoplastic transformation in terms of age, sex, number of polyps detected per patient, location, macroscopic appearance such as erosion, hyperemia. CONCLUSIONS Neoplastic transformation of gastric HPs had significant relationships with 1 cm in size, pedunculated shape, postgastectomy state, and synchronous neoplastic lesion. Therefore, endoscopic polypectomy should be considered in these HPs to avoid the risk of missing HPs with neoplastic potential.

Abstract
Since the discovery of Helicobacter pylori in 1982, the development of several treatment guidelines has allowed a consensus on the indications for H. pylori eradication. Beyond these currently accepted indications, including various upper gastrointestinal disorders and extragastric diseases, a significant amount of new information regarding H. pylori eradication is emerging. Certain types of acute gastritis, such as nodular gastritis, hypertrophic gastritis, Ménétrier's disease, hemorrhagic gastritis, and granulomatous gastritis are reversible after H. pylori eradication. Further, for chronic gastritis, closed-type atrophic gastritis and complete-type intestinal metaplasia appear to be more reversible after H. pylori eradication than open-type atrophic gastritis and incomplete-type intestinal metaplasia. Eradication can also be considered in subjects younger than 40 years who have a family history of gastric cancer and in subjects with long-term medications that might lead to bleeding (antiplatelet agents) or atrophy (proton pump inhibitors). Emerging evidence indicates that H. pylori eradication could be an effective treatment for some extragastric diseases that are unresponsive to conventional therapy. In such conditions, routine screening for eradication of H. pylori has not previously been recommended; a "test-and-treat" approach is suggested in the aforementioned situations. Given that H. pylori eradication is effective when the gastritis is reversible, future indications should be expanded to include acute gastric lesions that show marked improvement upon H. pylori eradication rather than just focusing on chronic gastric lesions. Future indications for H. pylori eradication should focus more on reversible lesions before preneoplastic conditions develop.

Abstract
Hyperplastic (inflammatory) polyps (HPs) of the gastric corpus and antrum typically develop in association with chronic gastritis. However, little is known regarding the etiology, pathologic features, and natural history of HPs of the gastroesophageal junction (GEJ). We have noted, anecdotally, that GEJ HPs often occur in patients without gastric pathology. The aim of this study was to evaluate the clinical, pathologic, and outcome features of patients with HPs of the GEJ, and to compare the data with a control group of individuals with HPs in the gastric corpus or antrum. One hundred thirty-four consecutive polyps of the GEJ were identified by a 5-year search through the pathology files of a major tertiary-care hospital. Of these, 46 (36%) polyps from 46 patients met the pathologic criteria for HPs and formed the basis of this study. The 46 study patients, and their polyps, were evaluated for a wide variety of clinical, endoscopic, and pathologic features including outcome on follow-up endoscopy. The findings were compared with 46 HPs from 46 patients of the distal stomach (antrum or corpus) that were obtained randomly from the same 5-year period. Compared with patients with gastric antral or corpus HPs, patients with HPs of the GEJ were significantly younger in age (mean age, 55.9 y vs. 63.0 y; P=0.04). Pathologically, GEJ HPs showed a significantly higher rate of multilayered epithelium (P=0.06) and association with Barrett esophagus (BE) (P=0.0001) compared with distal gastric HPs. All BE-associated GEJ HPs were associated with either ultrashort (<1 cm) or short segment (1 to 3 cm) BE. All other pathologic variables, including intestinal metaplasia, were similar to those of distal gastric HPs. In a subanalysis, BE-associated GEJ HPs (33% of all GEJ HPs) showed a higher male to female ratio and a higher rate of intestinal metaplasia compared with all other HPs. Furthermore, none of the BE-associated GEJ HPs were associated with chronic active gastritis versus the non-BE-associated GEJ HPs, although this was not statistically significant. Only 1 HP (from the GEJ) from both the study and control groups was associated with a neoplasm (signet-ring cell carcinoma). On follow-up, 1 patient with a GEJ HP and 4 with distal gastric HPs developed recurrent HPs and none of the patients from either patient group developed dysplasia or carcinoma. In conclusion, unlike HPs of the gastric corpus or antrum, a significant proportion of HPs of the GEJ arise in association with BE and without gastric pathology. In patients with BE, the columnar-lined segment is often ultrashort, and thus, an HP may be the first clinical/endoscopic manifestation of that disorder.

Abstract
BACKGROUND Long-term observational studies assessing the incidence of type I gastric carcinoid (typeIGC) in patients with chronic atrophic gastritis are few. AIM To evaluate the occurrence of typeIGC at diagnosis and during follow-up and to identify patient features associated with the presence of typeIGC in a cohort of chronic atrophic gastritis patients. METHODS Three hundred and sixty-seven chronic atrophic gastritis patients [245 women, age 54 (18-79) years] underwent regular follow-up by gastroscopy. The incidence of typeIGC was determined in chronic atrophic gastritis patients with at least 2 years of follow-up (n = 214). Baseline clinical and histological features were analysed as factors associated with the presence of typeIGC by univariate analysis. RESULTS Type I gastric carcinoid was diagnosed in nine (2.4%) patients at the moment when chronic atrophic gastritis was diagnosed. After 1463 person-years, six patients developed typeIGC with an annual incidence rate (person-year) of 0.4%. Patients with typeIGC had significantly higher levels of gastrin, chromogranin A and more frequently the presence of body polyps and ECL-dysplasia compared with chronic atrophic gastritis patients without typeIGC. CONCLUSIONS This cohort study shows that typeIGC is a rare complication in patients with chronic atrophic gastritis, and the presence of body polyps and ECL-dysplasia at gastroscopic/histologic evaluation is strongly associated with the presence of typeIGC.
