The aim of the study was to ascertain the existence of intestinal metaplasia in gastric mucosa of patients with gastric carcinoma coupled with H. pylori positive chronic atrophic gastritis and possible connection of IM with the development of gastric carcinoma. The paper presents prospective study that included 50 patients with gastric carcinoma and 50 patients with chronic atrophic H. pylori positive gastritis. All the patients were subjected to gastroscopy as well as biopsy targeted at antrum, lesser curvature and corpus and at the area 1-2 cm removed from tumor lesion. Biopsy samples were sliced by microtome and stained. We analyzed presence, frequency and severity of inflammatory-regenerative, metaplastic and dysplastic changes in the mucosa and evaluated their prognostic value. We typed IM immunohistochemically. This study confirmed responsibility of H. pylori for inflammatory events in gastric mucosa in patients with gastriccarcinoma. According to our findings incomplete IM of types IIa and IIb as precancerous lesion is responsible for the development of gastriccarcinoma and is associated with chronic atrophic gastritis grade I and II (92% of subjects, p=0.0097, h=1, p=0.01). Thus, the finding of incomplete intestinal metaplasia may be used as an indicator for early gastric carcinoma detection. Patients with patho-histologically verified incomplete intestinal metaplasia associated with active chronic atrophic gastritis of levels I and II represent risk group for the development of gastric carcinoma of intestinal type.

Background and aim. Atrophic gastritis is a precancerous gastric lesion, therefore its early detection is a priority in preventing gastric cancer. The aim of the present paper is to develop a narrative synthesis of the present knowledge on diagnostic methods of chronic atrophic gastritis. Methods. A literature search was carried out on main databases: PubMed, Hinari, SpringerLink and Scopus (Elsevier) for the period 2000-2020. The searched keywords were: chronic atrophic gastritis, intestinal metaplasia and dysplasia + diagnosis. Inclusion criteria were focused on the articles about the invasive and non-invasive diagnosis of chronic atrophic gastritis and of precancerous gastric lesions, intestinal metaplasia and dysplasia; exclusion criteria were articles published before 2000 and those that did not include the proposed theme. Results. The search returned 575 papers addressing the topic of precancerous lesions. From these, 60 articles were qualified representative for the materials published on the topic of this synthesis article, being those that met the inclusion criteria. The data emphasize the need to use upper digestive endoscopy with biopsies for the diagnosis of chronic atrophic gastritis. However serological diagnosis is available as alternative mainly recommended in follow up. Conclusions. There are two main methodological approaches for the evaluation of chronic atrophic gastritis as a precancerous gastric lesions: invasive examination, which requires histological analysis of biopsy samples taken during upper digestive endoscopy, being the "gold standard" for diagnosis, and non-invasive serological examination using markers of gastric function.

Background: The purpose of the study was to see whether chronic alcohol abuse had any effect on the gastric mucosa in a population already affected by a high prevalence of Helicobacter pylori.Methods: 35 males with a history of chronic alcohol abuse were compared with 35 males who were abstinent or social drinkers. All subjects had complaints of dyspepsia. All subjects underwent endoscopy and targeted biopsies were taken from three specific sites in the stomach, namely body, antrum and incisura. Biopsies were studied to look for changes of atrophic gastritis and intestinal metaplasia. The presence or absences of H. pylori on the tissue biopsy were also recorded.Results: Atrophic gastritis were only assessable in 24 alcoholic patients and 21 non-alcoholic patients due to the inadequacy of the depth of the biopsy. AG were found to be equally distributed in both the groups. 23 (64.9%) patients in the alcoholic group and 19(54.5%) in the control group had AG (OR-1.54, p=0.47). Intestinal metaplasia was seen in 10 (28.5%) alcoholic group and 12 (34.2) in the control group (OR-0.65, p=0.45). Of the 42 subjects detected to have AG, 16 (38.1%) had IM. However, IM were always associated with AG. In addition, H. pylori were not seen to be different in the two groups. H. pylori were positive in 18 (51.4%) alcoholic and14 (40%) non-alcoholic patients (p=0.33).Conclusions: Chronic alcohol abuse doesn’t appear to have any major impact on the gastric mucosa in terms of producing premalignant lesions such as atrophic gastritis or intestinal metaplasia or enhancing the prevalence of H. pylori.

Gastric cancer is the fourth most common cancer and the second leading cause of cancer death worldwide. Although the global incidence of gastric cancer has been decreased dramatically in recent decades, north and northwest of Iran have the highest incidence rate of gastric cancer. Whilst the surgical procedures for gastric cancer have been improved, there is no cure for that. The intestinal type of GC results from pre-neoplastic conditions including atrophic gastritis, intestinal metaplasia and dysplasia. Trefoil Factors Family proteins (TFFs) are small and stable molecules secreted by the mammalian gastrointestinal tract. TFFs constitute a family of three peptides (TFF1, TFF2and TFF3) that are widely expressed in a tissue specific manner in the gastrointestinal tract. Variable TFFs expression in gastric cancer and pre-neoplastic lesions has been found. TFF1 has a tumor suppressor activity and inhibits tumorogenesis in gastric cancer. Its expression decreases in gastritis, gastric atrophy, dysplasia, intestinal metaplasia and gastric cancer.TFF2 has a protective effect on gastrointestinal epithelium. As a prognostic factor, TFF2 expression decreases in gastric ulcer, chronic atrophic gastritis and gastric cancer. TFF3 is considered as an oncogenic factor in gastric tissues. Whilst the normal gastric tissues don’t express TFF3, it increases in intestinal metaplasia. Therefore, more studies are necessary to clarify the role of TFFs in GC and pre-neoplastic conditions. This review has focused on elucidating the important role of TFFs in gastric cancer and pre-neoplastic lesions.
