In recent years, domestic and foreign scholars have carried out extensive research on the prognostic factors of gastric cancer. Among them, non-specific inflammatory markers and nutritional indicators are the most concentrated in gastric cancer. C-reactive protein, as an acute phase protein, has been widely used to diagnose acute and chronic inflammation throughout the body. Prealbumin is a sensitive indicator of nutrition with a shorter half-life, which can quickly reflect the nutritional status of the body. At present, C-reactive protein and prealbumin as sensitive indicators of inflammation and nutrition, have shown certain predictive value in terms of postoperative complications and prognosis of gastric cancer. This article reviews the use of C-reactive protein, prealbumin and their ratios in predicting postoperative complications and prognosis of gastric cancer, aiming to provide a reference for the diagnosis and treatment of patients after gastric cancer.
