Risk Assessment and Syndrome Evolution Models Combining Traditional Chinese Medicine and Modern Medicine Indicators for Chronic Atrophic Gastritis Malignant Transformation: a Registry Study
Chronic atrophic gastritis (CAG) is acknowledged as the precancerous stage of gastric cancer (GC). The present study aims to developed risk assessment and syndrome evolution models of CAG malignant transformation events combining TCM indicators with modern medicine indicators. The proposed study is a registry study based participant survey conducted in 4 hospitals in Beijing, China. After obtaining informed consent, a total of 2000 study patients diagnosed with CAG will be recruited. 10-year follow-ups are carried out on-site in hospitals and off-site by telephone to track malignant transformation events.
• (1) 18-75 years of age; (2) Meeting diagnostic criteria of CAG after upper gastrointestinal endoscopy; (3) Willing to cooperate with data, tissue sample, and blood sample collection during recruitment; (4) Willing to respond truthfully and timely to researcher queries after recruitment, able to cooperate with data, tissue sample and blood sample collection during follow-ups; (5) Willing to sign informed consent.
