Core Tip
Core tip: Although helicobacter pylori (H. pylori) infection is the most important risk factor for gastric cancer (GC) development, eradication of this bacteria does not guarantee the elimination of GC risk, as pre-neoplastic lesions may have already developed. It is therefore necessary to identify patients at high-risk for GC after H. pylori eradication by either endoscopy with histologic assessment or non-invasive testing. Long-term endoscopic surveillance is advisable for high-risk patients. Future studies are necessary to investigate medications that may modify the GC risk after H. pylori eradication.
