A Prospective Study of Gastric Cancer Screening Based on Fecal Multi-Target DNA Analysis Combined With a Risk Questionnaire
This is a prospective study designed to evaluate the efficacy of a multi-target fecal DNA test for the early detection of gastric cancer. The test combines Helicobacter pylori gene detection with analysis of fecal methylated DNA markers. The primary objective is to assess whether each method, individually or in combination, can facilitate earlier diagnosis of gastric cancer. All participants will undergo the multi-target fecal DNA test and complete the gastric cancer risk questionnaire.
