Summary

The goal of this cross-sectional study is to evaluate epigenetic modifications in gastric carcinogenesis, mainly in H. pylori gastritis vs gastric carcinoma. The main question\[s\] it aims to answer are: * How does H. pylori infection cause gastric cancer? * Can DNA methylation and other epigenetic changes predict and affect the development of gastric cancer? Formalin-fixed-paraffin-embedded tissue specimens will be obtained and reviewed for comparison between epigenetic changes in H. pylori gastritis and gastric adenocarcinoma.
