Abstract: Objective The objectives of this study were to use Nutrition Risk Screening 2002(NRS2002)to conduct nutritional assessment research on patients with advanced cancer in our hospital,and to assess the patients′ nutritional deficiencies,nutritional risk and nutritional support,and to discuss the nutritional status and clinical indicators of patients with different tumor types in order to provide a scientific evidence for individualized nutritional support.Methods Patients with advanced tumors met the requirements were enrolled from January 2016 to February 2017.Nutritional questionnaires and anthropometry were conducted and recorded the information of measurements and relevant laboratory tests.NRS2002 was used to screen nutritional risk of patients.Results The nutritional insufficiency rate was 19.54% in 517 patients with advanced cancer and 49.52% in nutrition risk.The proportion of nutrition-free patients receiving nutritional support was 14.56%,and the nutritional support patients with nutritional support were 63.67%.The average length of hospital stay was(14.43±11.82)days for patients with nutritional risk,and(8.29±6.93)days for patients without nutritional risk.The incidence of nutritional risk in patients with digestive tract cancer was higher than other tumor types.Conclusion As an effective nutritional screening tool,NRS2002 can help clinicians to screen the potential nutritional risk of patients in oncology and provide the basis for patients to develop rational nutrition support.
