- Abstract: Gastric cancer has become the world's fourth most common malignant tumor, and the second leading cause of cancer death worldwide. Helicobacter pylori(H.pylori) infection is a major risk factor of occurrence and development of gastric cancer. In the multistage pathogenesis of gastric cancer, H.pylori infection induces chronic active gastritis slowly, which develops into gastric cancer in the end through precancerous stage of atrophic gastritis, intestinal metaplasia and hyperplasia. Related researches prove that eradication of H.pylori, particularly in the early stage, can effectively prevent the occurrence of gastric cancer. In some cases, the eradication of H.pylori can prevent the development of gastric precancerous lesions and reverse them. This paper will elaborate on the role of H.pylori eradication in the prevention of gastric cancer.
