BACKGROUND: Gastric intestinal metaplasia (IM) is regarded as a premalignant lesion, conferring risks for gastric cancer development. An intestinal transcription factor, CDX2, plays a vital role in establishing and maintaining IM. SOX2, an HMG-box transcription factor, is expressed in normal gastric mucosa and downregulated in IM. Therefore, it is important to elucidate the mutual interaction of SOX2 and CDX2 in gastric IM. AIMS: This study aims to evaluate the negative correlation between SOX2 and CDX2 in mRNA expression and promoter methylation and to illuminate the effect of SOX2 on the promoter methylation of CDX2...

Endometriosis of the appendix can be an incidental finding or a cause of appendicitis, intussusception, perforation or retention mucocele. Intestinal metaplasia of appendiceal endometriosis may occur, which can lead to a misdiagnosis of low-grade appendiceal mucinous neoplasm. On a retrospective search of the pathology database from 2001 to 2015, we identified 78 appendiceal endometriosis cases and intestinal metaplasia was present in 10/78 (13%) cases. In most of the cases (90%), the foci of intestinal metaplasia were mainly localized close to the mucosa...

One-anastomosis gastric bypass is an alternative to the "gold-standard" Roux-en-Y gastric bypass. This technique appears to be safe and efficient, but controversy remains regarding the long-term theoretical risk of subsequent biliary reflux and its possible complications, such as cancer. The aim of the present narrative review was to summarize some of the current thoughts on biliary reflux. Research has established that exposure to chronic bile reflux in humans and rats (outside the "bariatric surgery" box) induce esophageal intestinal metaplasia and esophageal adenocarcinoma...

Helicobacter pylori, a gastroenteric pathogen believed to have co-evolved with humans over 100,000 years, shows significant genetic variability. This motivates the study of different H. pylori strains and the diseases they cause in order to identify determinants for disease evolution. In this study, we used proteomics tools to compare two H. pylori strains. Nic25_A was isolated in Nicaragua from a patient with intestinal metaplasia, and P12 was isolated in Europe from a patient with duodenal ulcers. Differences in the abundance of surface proteins between the two strains were determined with two mass spectrometry-based methods, label-free quantification (MaxQuant) or the use of tandem mass tags (TMT)...

BACKGROUND: Endoscopic surveillance of Barrett's esophagus (BE) is probably not cost-effective. A sub-population with BE at increased risk of high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) who could be targeted for cost-effective surveillance was sought. METHODS: The outcome for BE surveillance from 2003 to 2012 in a structured program was reviewed. Incidence rates and incidence rate ratios for developing HGD or EAC were calculated. Risk stratification identified individuals who could be considered for exclusion from surveillance...

BACKGROUND: Gastroesophageal reflux disease (GERD) has become a major health problem globally, affecting patients' health-related quality of life (HRQOL). Barrett's esophagus (BE) is a precancerous lesion associated with GERD. BE patients might not only suffer from HRQOL losses by GERD but also face psychological distress due to the increased risk of developing cancer. However, the majority of patients in Asia have shorter BE segment which is different from the West. This study aimed to determine whether the HRQOL in BE patients were worse than in healthy referents in Taiwan...

Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens...

Gastric cancer is associated with high morbidity and mortality rates worldwide. Identifying individuals at high risk is important for surveillance and prevention of gastric cancer. Having first-degree relatives diagnosed with gastric cancer is a strong and consistent risk factor for gastric cancer, but the pathogenic mechanisms behind this familial aggregation are unclear. Against this background, we reviewed the risk factors for gastric cancer in those with a first-degree relative with gastric cancer, and the possible causes for familial clustering of gastric cancer including bacterial factors, inherited genetic susceptibility, environmental factors or a combination thereof...

BACKGROUND: Intestinal metaplasia is a precursor lesion of gastric cancer. Infection by Helicobacter pylori is the principal cause of metaplasia. While evidence of the regression of metaplasia after treatment to eradicate this infection has been demonstrated, controversy remains with regard to this subject. OBJECTIVE: The objective of this study was to determine the frequency of the regression of gastric intestinal metaplasia one year after the eradication of Helicobacter pylori...

Kinesin family protein 2A (KIF2A), an M-type nonmotile microtubule depolymerase, has attracted attention for its role in carcinogenesis and poor prognoses in various human cancers. In this study, we aimed to evaluate the expression of KIF2A and its robustness and potential to predict clinical outcomes in gastric cancer (GC) patients. The messenger RNA (mRNA) expression of KIF2A was determined in 24 pairs of cancerous and adjacent nontumor tissues by real-time polymerase chain reaction. Immunohistochemistry of KIF2A was performed on a tissue microarray composed of 461 GC and 65 matched adjacent nontumor tissues removed during surgeries and 18 chronic gastritis, 15 intestinal metaplasia, and 37 low-grade and 62 high-grade intraepithelial neoplasias acquired through gastric endoscopic biopsies...

Helicobacter pylori organisms have been observed deep within the stomach mucosa with an "intracellular" appearance, though the clinicopathologic characteristics of such cases remain poorly understood. We analyzed eighteen cases of deep mucosal H. pylori and associated clinical (sex, age, history of H. pylori infection, or proton pump inhibitor (PPI) use, medications, smoking, alcohol use, co-morbidities, treatment response treatment) and pathological (presence of lymphoid aggregates, intestinal metaplasia, PPI effect, active and/or chronic inflammation, quantity of invasive versus surface H...

Barrett's esophagus (BE) is the replacement of the normal esophageal squamous epithelium by a columnar lining epithelium. It is a premalignant condition for the development of adenocarcinoma of the esophagus and esophagogastric junction. BE is associated with gastroesophageal reflux which might change the expression profile of key transcription factors involved in the establishment of tissue differentiation, namely, SOX2 (associated with esophageal and gastric differentiation) and CDX2 (associated with intestinal differentiation)...

Barrett's esophagus is an endoscopically visible metaplasia of the columnar epithelium in the esophagus with histological detection of a specialized intestinal metaplasia. The circumferential and longitudinal extent are described endoscopically using the Prague classification. Barrett's esophagus mostly occurs as the result of gastroesophageal reflux disease. The risk of developing esophageal adenocarcinoma is increased but the absolute risk is low with 0.10-0.15 % per year. According to guideline recommendations, screening for Barrett's esophagus as well as endoscopic and biopsy surveillance should be limited to high risk groups...

Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like)...

Adenocarcinoma with osteoblastic metastases is classically seen in prostate, breast, and lung primaries. Less common primary sites include thyroid, kidney, and stomach. We present two cases of primary gastrointestinal adenocarcinoma with metastatic osteoblastic activity from two previously unreported sites. The first case represents an esophageal adenocarcinoma arising in a background of intestinal metaplasia that metastasized with osteoblastic activity to the deltoid muscle. The second case demonstrates a Stage IV sigmoid colon adenocarcinoma with osteoblastic metastases to the liver and lymph nodes...
