Colombian congress of digestive diseases. This region also has a high gasgrico of premalignant lesions including chronic atrophic gastritis, intestinal metaplasia and mild dysplasia as well as high prevalence of Helicobacter pylori infections. Gastric cancer: Overview These observations would support the hypothesis that race and ethnicity are important, as well as the age of acquisition of the infection [ 38 ]. Intestinal metaplasia arises most often in the lesser curvature of the stomach, but may be observed anywhere in the stomach. However, the role of EBV in gastric carcinogenesis is not yet clearly defined. If there is dysplasia with a visible lesion at endoscopy, it should be classified according to stage and resection of the lesion must be carried out See other articles in PMC that cite the published article.

Muran Evaluation of dysplasia in gastrointestinal diseases. There is a great need for non-invasive screening tests that can be applied to large populations to assess cancer risk or detect early gastric cancer cases.
Diffuse type adenocarcinomas have a more aggressive behavior and worse prognosis than those of the intestinal type. The role of nutrition Dietary and environmental factors may be significantly different between the mountainous and coastal regions. In the initial bastrico lesion, atrophic gastritis is characterized by the death of the parietal cells and the loss of the glandular epithelium that covers the mucosa of the stomach 4.
This precancerous process was described in by Correa et al. This phenomenon has been described in other parts of the world and has stimulated numerous epidemiological studies aimed at finding its causes. General measures for gastric cancer prevention are the adequate consumption of fresh fruits and vegetables, the avoidance of excessive salt intake and the avoidance of exposure to tobacco smoke. In some instances, after decades of continuous bacteria-host dialogue, the balance is compromised, leading to peptic ulcer disease and cabcer cancer.

A greater prevalence of cag -positive strains has been observed in regions with a greater incidence of gastric cancer This syndrome is caused by a variety of mutations of the gene encoding E-cadherin, a cell adhesion protein essential cancr the maintenance of epithelial tissue architecture BabA adheres to the Lewis b blood group antigen present on the membrane of gastric epithelial cells.
As few studies have been conducted that ccancer the prevalence of intestinal metaplasia in the general asymptomatic population, it is necessary to carry out an upper endoscopy gaztrico a histological examination. These differences are attributable to variation in a DNA motif in the cagA promoter region The point becomes even more important when we take into account the study of the pO1 ca project report of the National Cancer Institute of the USA 3 which says that invasive gastric cancer is preceded by a prolonged process that starts during childhood as a result of the Helicobacter pylori infection.
