Abstract:About 40%-80% of patients with malignant tumors have nutrition-related problems, and malnutrition produces adverse effects on the treatment and prognoses of patients receiving radiotherapy. Medical nutrition therapy aims to help solve the malnutrition of tumor patients undergoing radiotherapy, which is of great significance to improve the nutritional status of patients and promote the comprehensive treatment effect of cancer. Patients receiving radiotherapy should be offered whole-course nutrition management during the peri-radiation period. Before, during, and after radiotherapy, NRS-2002 is utilized for nutritional risk screening;PG-SGA is employed for nutritional assessment when necessary;and standardized individualized nutritional support is provided in combination with RTOG acute and late radiation injury grading. This consensus supplemented and refined the nutritional support process for patients receiving radiotherapy, further discussed the standardized management process and standards of nutrition for radiotherapy in combination with guidelines on nutrition in cancer patients, so as to provided standards and reference for clinicians of oncology radiotherapy to develop standardized nutritional support.
