Abstract Abstract: The incidence of malnutrition was high in cancer patients receiving radiotherapy. Malnutrition may reduce the antitumor effect and increase the radiotherapy adverse reactions. NRS 2002 is recommended for nutritional risk screening, and PG-SGA is recommended for nutritional assessment. The cancer patients receiving radiotherapy should carry out whole-process nutrition management during the peri-radiation period. We should correctly assess the nutritional status of patients using PG-SGA before, during and after radiotherapy and acute radiation injury during and after radiotherapy according to RTOG criteria. Then, we can select the standardized and individualized nutrition treatment method according to the assessment result. Nutritional therapy should follow the "five-stage model". Enteral nutrition access should follow the "four-stage model". Only when the patient is unable to obtain adequate nutritional needs through enteral nutrition or the presence of severe radioactive mucositis, radiation enteritis or intestinal failure, it is recommended to combine partal or whole enteral nutrition in time. The recommended amount of energy intake for radiotherapy patients with malignant tumor is 25~30kcal/(kg·d). It should be adjusted dynamically according to tumor burden, stress state and acute radiation injury during radiotherapy. Cancer patients receiving radiotherapy are recommend higher protein intake, and 1.5~ 2.0g/(kg·d) is recommended for patients with severe malnutrition. For patients with cachexia, it can be increased to 2.0g/(kg·d).
