Prospective Gastric Cancer Screening Using Helicobacter Pylori High-Risk Single Nucleotide Polymorphism Detection

Summary

This is a prospective study designed to compare the performance of fecal H. pylori gastric cancer susceptibility analysis and the gastric cancer risk questionnaire for the early detection of gastric cancer. The primary objective is to assess whether each method, individually or in combination, can facilitate earlier diagnosis of gastric cancer. All participants will undergo fecal H. pylori gastric cancer susceptibility testing and complete the gastric cancer risk questionnaire.
