摘要:
Helicobacter pylori(H.pylori) infection was thought to be the main cause of gastric cancer,and its eradication showed improvement in gastric inflammation and dec-reased the risk of gastric cancer.Recently,a number of studies reported the occurrence of gastric cancer after successful eradication.Patients infected with H.pylori,even after eradication,have a higher risk for the occurrence of gastric cancer when compared with uninfected patients.Metachronous gastric cancer occurs frequently following the endoscopic removal of early gastric cancer.These data indicate that metachronous cancer leads to the occurrence of gastric cancer even after successful eradication of H.pylori.The pathogenesis of this metachronous cancer remains unclear.Further research is needed to identify biomarkers to predict the development of metachronous gastric cancer and methods for gastric cancer screening.In this article,we review the role of the H.pylori in carcinogenesis and the histological and endoscopic characteristics and risk factors for metachronous gastric cancer after eradication.Additionally,we discuss recent risk predictions and possible approaches for reducing the risk of metachro-nous gastric cancer after eradication.
