In addition, cardia adenocarcinomas seem to have a more aggressive natural history with deeper gastric wall invasion, greater lymph node involvement, and a worse prognosis than distal adenocarcinomas 5, Previously, it was left to the judgment of the physicians involved to classify the tumors located at the esophagogastric junction as esophageal or gastric.

It is recommended that patients undergoing upper gastrointestinal endoscopy due to gastrointestinal symptoms have a sampling of at least five biopsies, including two of gastric antropyloric mucosa greater and lesser curvatureone of the incisura angularisand two of the gastric body lesser and greater curvature.

Department of Digestive Diseases. Helicobacter pylori and gastric adenocarcinoma. The last type is usually observed in diffuse type adenocarcinomas and it is known as linitis plastica. This migratory process can be interpreted as an indirect measure of the extent of the nariio to the gastric mucosa, and as such, as a phenomena that we may consider to be an indicator for risk of carcinoma 21,22, Gastritis was graded as negative 0mild 1moderate 2severe 3 and undifferentiated 9. All of the above emphasis on more frequent checkups, especially for younger patients, aims at making early detection of gastric cancer a priority and at observing regression of premalignant lesions resulting from intervention by health promotion and disease prevention medical groups.

Each slice was prepared with hematoxylin eosin stain for routine histological examination of with an especially modified Giemsa stain for detection of Helicobacter pylori.

Virulence- Associated genotypes of Helicobacter pylori: This measure is not recommended due to the risk of the appearance of antimicrobial-resistant strains, not only for H.

Non-atrophic chronic gastritis was found in 35 Acta Pathol Microbiol Scand. The observation of higher gastric cancer rates in the mountainous areas is not universal: Serum pepsinogen I is secreted in the oxyntic mucosa, and PGII is secreted in both oxyntic and antropyloric mucosa.

The prevalence of premalignant lesions varies greatly according to geographic zones and age which accounts for the importance of their prevalence in the region in question.
