Gastric cancer is a common heterogeneous malignancy that is pathologically characterized by the development of chronic atrophic gastritis and dysplasia of the epithelium. The pathogenic mechanisms at the molecular level are completely unclear. In the present study, we first address the expression network and miRNA-lncRNA-mRNA interaction in the malignant transformation process from normal mucosa and atrophic gastritis to a tumor. First, the long non-coding RNA (lncRNA), micro RNA (miRNA) and messenger RNA (mRNA) expression profiles of normal gastric mucosa, atrophic gastritis, gastric cancer and the peri-tumor tissues were analyzed using microarrays...

Gastric cancer (GC) is the fifth most common type of malignancy and the third leading cause of cancer-associated mortality worldwide. It is necessary to identify novel methods aimed at improving the early diagnosis and treatment of GC. MicroRNA expression profiles in the plasma of patients with GC have demonstrated a potential use in the opportune diagnosis of this neoplasm. However, there are currently no standardized targets for use in the normalization of microRNA Cq values for different neoplasms. The present study tested two normalization approaches while analyzing plasma derived from patients with GC and non-atrophic gastritis...

BACKGROUND: Objective was to quantify biases in screening for gastric cancer when comparing attenders to nonattenders using serum pepsinogen I (SPGI) level as primary test. METHODS: In mid 1990s, all men aged 51-65 years from two Finnish cities were invited to SPGI screening. Mortality and premature mortality in attenders were compared to nonattenders. Efficacy of screening was studied by 15 years' follow-up of standardized mortality ratio (SMR) and potential years of life lost (PYLL) due to gastric cancer...

The approvals and provisions of the Management of Helicobacter pylori infection-the Maastricht V/ Florence Consensus Report and those of the Kyoto Global Consensus Conference on H. pylori-associated gastritis, concerning with the primary and secondary prevention of gastric cancer (GC), unambiguously suggest that H. pylori infection is the most important risk factor of GC. Accordingly, the basis for the primary and secondary prevention of GC is the optimization of H. pylori eradication therapy. The clear direct relationship of the risk of GC to the severity and extent of atrophic gastritis, intestinal metaplasia and dysplasia and no reversal of intestinal metaplasia and dysplasia in the presence of H...

BACKGROUND: Magnifying narrow-band imaging (M-NBI) can reportedly help predict the presence and distribution of atrophy and intestinal metaplasia in the gastric corpus. However, the micro-mucosal pattern of the antrum shown by M-NBI differs from that of the corpus. We studied the distribution and histology of the micro-mucosal pattern in the antrum based on magnifying endoscopy. METHODS: Endoscopic images of the greater curvature of the antrum were evaluated in 50 patients with chronic atrophic fundic gastritis (CAFG)...

In Indonesia, endoscopy services are limited and studies about gastric mucosal status by using pepsinogens (PGs) are rare. We measured PG levels, and calculated the best cutoff and predictive values for discriminating gastric mucosal status among ethnic groups in Indonesia. We collected gastric biopsy specimens and sera from 233 patients with dyspepsia living in three Indonesian islands. When ≥5.5 U/mL was used as the best cutoff value of Helicobacter pylori antibody titer, 8.6% (20 of 233) were positive for H...

BACKGROUND: Serum pepsinogen (PG) test, as an indicator of gastric mucosal atrophy, reflects the functional and morphologic status of gastric mucosal and it is suggested to serve as a useful predictive marker for patients with gastric cancer (GC). The available classifications of gastritis, known as the Operative Link on Gastritis Assessment (OLGA) and Operative Link on Gastritis Intestinal Metaplasia (OLGIM), integrating the severity and topography of atrophy/intestinal metaplasia (IM), have been gradually accepted and used in screening for GC in recent years...

BACKGROUND AND AIM: Western studies have suggested two distinct etiologies of esophagogastric junction (EGJ) cancer: Helicobacter pylori-associated atrophic gastritis and non-atrophic gastric mucosa resembling esophageal adenocarcinoma. The present study investigated whether endoscopic gastric mucosal atrophy can distinguish between these two types of EGJ adenocarcinoma. METHODS: Data were collected from patients with Siewert type II, T1 EGJ adenocarcinoma who underwent endoscopic or surgical resection at eight Japanese institutions in 2010-2015...

Helicobacter pylori infection triggers a cascade of inflammatory stages that may lead to the appearance of non-atrophic gastritis, multifocal atrophic, intestinal metaplasia, dysplasia, and cancer. Deleted in malignant brain tumors 1 (DMBT1) belongs to the group of secreted scavenger receptor cysteine-rich proteins and is considered to be involved in host defense by binding to pathogens. Initial studies showed its deletion and loss of expression in a variety of tumors but the role of this gene in tumor development is not completely understood...

Gastric cancer (GC) is still an extremely severe health issue with high mortality due to the lacking of effective biomarkers. In this study, we aimed to investigate the alterations of salivary protein glycosylation related to GC and assess the possibility of salivary glycopatterns as potential biomarkers for the diagnosis of GC. Firstly, 94 patients with GC (n = 64) and atrophic gastritis (AG) (n = 30), as well as 30 age- and sex-matched healthy volunteers (HV) were enrolled in the test group to probe the difference of salivary glycopatterns using lectin microarrays, the results were validated by saliva microarrays and lectin blotting analysis...

Gastric intestinal metaplasia, an intermediate lesion in the development of intestinal-type gastric cancer, is observed in the milieu of long standing non-atrophic gastritis and atrophic gastritis. Most patients with intestinal metaplasia remain asymptomatic unless cobalamin deficiency occurs secondary to loss of glands (that produce intrinsic factor and acid). Genetic events that predispose to development of gastric intestinal metaplasia remains an enigma. Mechanisms leading to the progression of atrophy to metaplasia still needs to be comprehensively explored...

BACKGROUND: Autoimmune gastritis (AIG) and adenocarcinoma-associated chronic atrophic gastritis (CAG) are both associated with oxyntic atrophy, but AIG patients demonstrate an increased risk of carcinoid tumors rather than the elevated risk of adenocarcinoma observed with CAG. We therefore sought to compare the characteristics of the metaplastic mucosa in AIG and CAG patients. METHODS: We examined markers for metaplasia (spasmolytic polypeptide expressing metaplasia (SPEM) and intestinal metaplasia) as well as proliferation (Ki67) and immune cell populations (neutrophils, macrophages, and eosinophils) in gastric sections from 16 female patients with autoimmune thyroiditis and AIG and 17 patients with CAG associated with gastric adenocarcinoma...

BACKGROUND AND AIM: Risk factors for progression of gastric atrophy have not been fully elucidated. The aim of this study was to evaluate the risk factors for the development of atrophic gastritis in patients with Helicobacter pylori (H. pylori ) infection. METHODS: We reviewed 206 H. pylori-infected patients retrospectively. Endoscopic gastric atrophy was classified into closed- and open-type. We conducted univariate and multivariate logistic regression analyses on the contribution of age, sex, body mass index, past history of cancer, the first-degree family history of gastric cancer, habitual smoking and alcohol drinking, and endoscopic findings of gastric ulcer or duodenal ulcer for open-type gastric atrophy...

Anemia is a frequent, although often underestimated, clinical condition accompanying thyroid diseases. In spite of the fact that anemia and thyroid dysfunction often occur simultaneously, the causative relationship between these two disorders remains ambiguous. Thyroid hormones stimulate erythrocytes precursors proliferation directly, as well as via erythropoietin production enhancement, whereas iron-deficient anemia negatively influences thyroid hormonal status. Thus, different forms of anemia might emerge in the course of thyroid dysfunction...

Neuroendocrine tumors (NETs) represent uncommon tumors arising from the excessive proliferation of enterochromaffin-like (ECL) cells (so-called Kulchitsky cell). Gastric NETs (GNET) represent less than 2% of all NETs and less than 1% of all stomach neoplasms. In particular, gastric NETs type 1 (associated to chronic atrophic gastritis and hypergastrinaemia) is the more frequent one, accounting for 70-80% of all GNET. A macrocytic anemia is a frequent manifestation of GNET type 1. The possibility that macrocytic anemia appear during therapy with methotrexate (MTX) is widely documented...
