Genetic polymorphisms of the cancer related gene andHelicobacter pylori infection in Japanese gastric cancer patients: An age and gender matched case–control study

Abstract

Atrophic mucosal change, indicated by serum pepsinogen levels, is possible a risk factor for gastric cancer. H. pylori infection and genetic polymorphisms of CYP2E1, L-myc, and GSTM1 genetic polymorphisms were not risk factors in this study.
