Abstract
Objective This study was performed to clarify the prevalence of raspberry-type gastric foveolar-type tumors, along with the time-course changes in the size and clinical course. Methods The subjects were 10,663 consecutive patients who underwent a medical checkup between April 2016 and March 2022, including an esophagogastroduodenoscopy (EGD) examination and determination of Helicobacter pylori infection status (uninfected, positive, post-eradication). The presence of characteristic reddish polypoid lesions in the stomach was investigated, and a diagnosis of raspberry-type gastric foveolar-type tumor was made based on histological findings. Results Thirty-eight cases had gastric polyps with a raspberry-like appearance on endoscopy, with 29 lesions in 28 cases endoscopically and histologically diagnosed as a raspberry-type gastric foveolar-type tumor. All of the affected subjects were determined to be H. pylori-uninfected. The prevalence of this type of lesion in all subjects was 0.26%, while that in the 6,635 H. pylori-uninfected subjects was 0.42%. An older age and the presence of a fundic gland polyp were found to be significant risk factors associated with the occurrence of the tumor. The mean size was 3.8±1.9 (range: 2-10) mm, and the location was in a fundic gland area in all affected subjects. Furthermore, examinations of previous EGD images revealed that two-thirds of the lesions had not changed in size, while follow-up EGD findings showed that lesions ≤5 mm in size had disappeared after a biopsy procedure. Conclusion The prevalence of raspberry-type gastric foveolar-type tumors was 0.42% in H. pylori-uninfected subjects. More than half of the lesions were too small to be removed by an endoscopic biopsy.

Abstract
Objective This study was performed to clarify the association of the degree of gastric mucosal atrophy (GMA) with the occurrence of gastric cancer in patients with Helicobacter pylori-eradicated status. Subjects and Methods The subjects were 3,058 patients (2,035 men, 1,023 women; mean age 57.9 ± 9.5 years old) with H. pylori eradication who underwent esophago-gastroduodenal endoscopy examinations as part of medical checkups conducted between April 2013 and March 2022. The gender, age at eradication, time since eradication, usage of anti-secretory drugs, degree of endoscopic GMA, and FGP prevalence were compared between subjects with and without gastric cancer occurrence. Results Gastric cancer was newly detected in 26 subjects (0.85%) during the study period, with an older age at H. pylori eradication and severe grade of endoscopic GMA being significant risk factors for its occurrence. The gender, smoking history, and usage of anti-secretory drugs were not significantly different between subjects with and without gastric cancer occurrence. A Cox regression analysis showed that an older age at eradication and the degree of GMA were risk factors significantly related to occurrence. Furthermore, the degree of GMA was inversely correlated with FGP development, and gastric cancer was not detected in 467 subjects with FGP prevalence. Conclusion An older age at the time of H. pylori eradication and the degree of GMA are significant risk factors for gastric cancer occurrence in H. pylori-eradicated patients. The FGP prevalence in subjects with H. pylori eradication was inversely associated with GMA, suggesting it was negatively related with gastric cancer occurrence.

Abstract
BACKGROUND AND STUDY AIMS Sporadic fundic gland polyps (FGP) are the most common type of gastric polyp, reported in 0.8%-1.9% of patients undergoing Esophagogastroduodenoscopy (EGD). Data on long-term outcomes of large FGP is limited. We aim to study the natural history of sporadic large (≥ 10 mm) FGPs. PATIENTS AND METHODS All adults who underwent EGD for any indication from April 2014 to December 2019 at a tertiary care center were retrospectively assessed, and patients with FGP (≥10mm) were identified. Data on baseline characteristics and long-term outcomes were recorded. Follow-up data were recorded for patients who underwent repeat endoscopy to evaluate for rates of dysplasia and cancer. RESULTS A total of 4,000 patients with a diagnosis of FGP were screened and 132 large, biopsy-proven FGPs were included in the final analysis. The most common indication for EGD was gastroesophageal reflux disease (61%). During a follow-up period of 3.2 years, the rate of dysplasia, was 4.0%. Subgroup analysis based on size (10-19 mm and ≥ 20 mm) showed no significant difference in overall outcomes. CONCLUSION Repeat EGDs for surveillance should not be routinely performed since large (≥10 mm) sporadic FGPs are mostly benign without significant malignant potential.

Abstract
Fundic gland polyps (FGPs) are the most common gastric polyps and have been regarded as benign lesions with little malignant potential, except in the setting of familial adenomatous polyposis. However, in recent years, the prevalence of FGPs has been increasing along with the widespread and frequent use of proton pump inhibitors (PPIs). To date, several cases of FGPs with dysplasia or carcinoma (FGPD/CAs) have been reported. In this review, we evaluated the clinical and endoscopic characteristics of sporadic FGPD/CAs. Majority of the patients with sporadic FGPD/CAs were middle-aged women receiving PPI therapy and without Helicobacter pylori (H. pylori) infection. Majority of the sporadic FGPD/ CAs occurred in the body of the stomach and were sessile and small with a mean size of 5.4 mm. The sporadic FGPs with carcinoma showed redness, irregular surface structure, depression, or erosion during white light observation and irregular microvessels on the lesion surface during magnifying narrow-band imaging. In addition, sporadic FGPs, even with dysplasia, are likely to progress to cancer slowly. Therefore, frequent endoscopy is not required for patients with sporadic FGPs. However, histopathological evaluation is necessary if endoscopic findings different from ordinary FGPs are observed, regardless of their size. In the future, the prevalence of FGPs is expected to further increase along with the widespread and frequent use of PPIs and decreasing infection rate of H. pylori. Currently, it is unclear whether FGPD/CAs will also increase in the same way as FGPs. However, the trends of these lesions warrant further attention in the future.

Sporadic foveolar-type gastric adenoma with a raspberry-like appearance in Helicobacter pylori-naïve patients. Virchows Arch 2021; 479:687-695.

Abstract
Sporadic foveolar-type gastric adenoma (FGA) has been described as an extremely rare polyp that is whitish and flatly elevated. However, we recently found that sporadic FGA with a raspberry-like appearance (FGA-RA) is not rare in Helicobacter pylori (H. pylori)-naïve gastric mucosa. We endoscopically or surgically treated 647 patients with gastric epithelial neoplasms in the last 5 years, with 7.7% (50/647) being H. pylori-naïve. Among these, 43 FGA-RAs were diagnosed based on histologic and endoscopic features in 34 patients, who were all enrolled in this retrospective study. All lesions were observed by white-light endoscopy (WLE) and narrow-band imaging with magnification endoscopy (NBIME). We subsequently analyzed their endoscopic and microscopic features and patient characteristics. The patients were 22 males and 12 females aged 57±23 years (mean±2SD). WLE showed raspberry-like small polyps mimicking gastric hyperplastic polyps in the oxyntic gastric compartment (body/fundus). Multiple growths were confirmed in 20.6% (7/34) of the patients. NBIME revealed irregularly shaped papillary/gyrus-like microstructures with abnormal capillaries. Histologically, all lesions were intraepithelial neoplasms, and most of lesions (62.8%, 27/43) exhibited low-grade dysplasia. Immunohistochemically, neoplastic cells featured strong and diffuse MUC5AC expression, negative or very low MUC6 expression, and negative MUC2/CD10 expression. They also showed Ki-67 hyperexpression with a mean labeling index of 59.4±48.7%. The coexistence of fundic gland polyps in the background mucosa was significantly higher in multiple FGA-RA cases than in solitary cases (100% vs. 55.5%, P< 0.05). FGA-RA is a newly suggested histologic variant of sporadic FGA whose occurrence is not rare in daily endoscopic practice.

Abstract
INTRODUCTION An increase in the incidence of duodenal adenocarcinoma has been recently reported. However, little is known about the risk factors for duodenal adenocarcinoma, which are important for screening purposes. We, therefore, aimed to conduct a systematic review to identify risk factors for non-ampullary duodenal adenocarcinoma. METHODS A medical literature search was performed using electronic databases, including PubMed, Cochrane Library, Japan Medical Abstracts Society, and Web of Science. Studies that assessed the association between dietary habits, lifestyle behaviors, comorbidities, and non-ampullary duodenal adenocarcinoma were extracted. The Newcastle-Ottawa Scale was used to assess the risk of bias in individual studies, and the Grading of Recommendations, Assessment, Development, and Evaluations approach was used to assess the quality of evidence across studies included in this review. RESULTS Out of 1,244 screened articles, 10 were finally selected for qualitative synthesis. In the general population, no consistent risk factors were identified except for Helicobacter pylori positivity, which was considered a risk factor in 2 studies, but the quality of evidence was considered very low because of the high risk of bias. In patients with familial adenomatous polyposis (FAP), Spigelman stage IV at initial endoscopy was considered a consistent risk factor in 3 studies. CONCLUSIONS There are currently limited data regarding risk factors for non-ampullary duodenal adenocarcinoma, and no conclusive risk factors were identified in the general population. However, in patients with FAP, Spigelman stage IV was identified as a consistent risk factor. Further studies are needed to improve diagnosis and support effective clinical management of this malignancy.
