An Observational Study on Gastric Cancer in High-risk Individuals

This study is designed as a prospective observational cohort study, aiming to assess the differences in the occurrence of gastric cancer and the progression of gastric cancer-related precancerous lesions between individuals who test positive or negative for fecal multi-target testing, with baseline negative gastric endoscopy results. The clinical outcomes between the two groups will be compared through long-term follow-up.
