OBJECTIVE Helicobacter pylori-associated atrophic gastritis is known to be a significant risk factor for gastric cancer. Among the well-known parameters of atrophic gastritis are the levels of serum gastrin-17 (G-17) and pepsinogen I (PG1), which are biomarkers of gastric antral and corpus mucosal activity, respectively. The aim of study was to compare the(More)
AIM To assess the possibility of non-invasive screening of atrophic chronic gastritis for preventing further development of gastric cancer. METHODS One hundred and seventy-eight consecutive Helicobacter pylori (H pylori)-positive dyspeptic patients after detection of serum levels of pepsinogen-1 (PG-1) and gastrin-17 (G-17) by enzyme immunoassay were(More)
PURPOSE To detect the Helicobacter pylori (H. pylori)-induced gastric precancerous lesions leading to cancer formation, and to evaluate the possibility of non-invasive screening of dyspeptic patients to identify those having high risk of gastric cancer. MATERIAL AND METHODS 178 consecutive H. pylori-positive dyspeptic patients after assessment of serum(More)
