Atrophic gastritis and gastric cancer / 国际肿瘤学杂志

ABSTRACT

In many cancers the chronic inflammation caused by microorganisms can be observed, espe-cially in gastrointestinal system. Atrophic gastritis is thought to be a precancerous lesion. Studies have approved that Helicobacter pylori plays an important role in the genesis and development of gastric caner. It is now known to be responsible for inducing chronic gastric inflammation that progresses to atrophy, metaplasia, dysplasia and gastric cancer.
