Identification of a high risk gastric cancer group using serum pepsinogen after successful eradication of <i><scp>H</scp>elicobacter pylori</i>

Abstract

In the identification of a high risk group for gastric cancer, we suggest that the optimal cut-off value of PGI/II after successful eradication of H. pylori is 4.5. PGI/II ≤ 4.5 in post-eradication includes more gastric cancer cases compared with the traditional PG method, and 75% of gastric cancer cases detected after eradication.
