2、utrition increases the risk of treatment toxicity and impairs outcomes of patients with cancer.Early nutrition interventions are recommended in properly identified patients for improving treatment tolerance and patient survival.Underestimation of malnutrition remains a significant issue since early
3、recognition of malnutrition may allow for early optimization of nutrition interventions to support patients during treatment.Patient self-screening for malnutrition has been reported as feasible in cancer,and relatives may also provide external information on nutrition.42023-5-12研究背景及目的01questions:W
4、hether patients with cancer and/or their relatives are aware of malnutrition and could improve the efficacy of nutri-tion interventions is unclear.However,the subjective awareness of malnutrition by the patients,their relat-ives,and physicians has not yet been assessed or compared.52023-5-12研究背景及目的0

12、nd lower than the 43.5%and 52%reported by Nourissat et al8 and Segura et al,9 respectively.One explanation could be the different proportions of pa-tients with GI locations:32%in our study compared with 17%and 34%in the studies by Pressoir et al7 and Nourissat et al,8 respectively,while in the study
13、 by Segura et al,9 the proportion of patients with pancreatic and lung cancers was higher.01182023-5-12讨论及总结0402Patients and relatives underestimated malnutrition while physicians overestimated it,indicating a low awareness of patients and relatives regarding malnutrition in cancer.Further studies are needed to improve the awareness of mal-nutrition in patients and their relatives as well as the efficacy of nutrition interventions.192023-5-12讨论及总结04请老师同学指正批评时间：2017.3.15Thanks for your attention202023-5-12
