Abstract

Helicobacter pylori  (H. pylori) is the most important etiologic factor for gastric cancer. It is one of the most common human pathogens, which colonizes in the mucus layer of the gastric epithelium in more than 50% of the population. The study include 78 samples of gastric cancer in addition to 42 blood samples. The results from 78 gastric cancer samples showed that gastric cancer can occur red at any age, but it increases in older ages and the incidence of H. pylori infected positive gastric cancer (HIP-GC) is higher than of H. pylori infected negative gastric cancer (HIN-GC). Male is the predominant in both groups and female affected by H. pylori more than male and the intestinal type was the predominant type.
