Abstract： The incidence of malnutrition in patients with malignant tumors is high, especially in patients with gastrointestinal cancer. In addition to the consumption of tumor itself and the release of specific factors, gastrointestinal tumors are often caused by inadequate or excessive loss of nutritional intake due to obstruction of the digestive tract, which further aggravates the degree of malnutrition in the patients. Perioperative malnutrition can increase the incidence of postoperative complications, prolong hospital stay, reduce quality of life, increase unplanned second surgical rates, and ultimately increase mortality. By using of effective nutrition screening tool for scanning patients with malnutrition, providing accurate and effective nutritional support treatment in the perioperative period, improving the nutritional status of patients with tumor, it can improve the tolerance of patients with tumor, reduce the adverse reaction and complication rate, improve curative effect, shorten hospitalization time, reduce hospitalization costs, thereby improving the clinical outcome of patients, and improve the quality of life and prolong the survival time. Therefore, perioperative nutrition screening and accurate nutrition therapy for gastrointestinal cancer patients are of great importance to improve the prognosis of patients with gastrointestinal cancer. From the aspects of the causes of malnutrition in patients with gastrointestinal cancer, the assessment and screening of nutritional status, the precision nutrition therapy, and the choice and application of the nutritional preparations, this paper illustrates the current research progress.
