Risk Assessment and Syndrome Evolution Models for Chronic Atrophic Gastritis Malignant Transformation

NCT03261934

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.
