Prognostic value of preoperative malnutrition assessment in patients with gastric cancer radical surgery
Objective To evaluate the application value of the Global Leadership Initiative on Malnutri-tion(GLIM)criteria in the patients with gastric cancer radical surgery,and to explore the relationship be-tween the malnutrition defined by GLIM criteria and the prognosis of the patients with gastric cancer radical surgery.Methods A total of 150 gastric cancer patients receiving radical surgical resection in Zhejiang Provin-cial Tongde Hospital from January 2014 to December 2017 were selected as the study subjects.All the study subjects were diagnosed as malnutrition and graded by the severity of malnutrition.The effect of malnutrition defined by GLIM criteria on the prognosis of the patients with gastric cancer radical surgery was evaluated by the Kaplan Meier survival curve and Cox regression analysis.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of GLIM criteria on the postoperative survival rate of the pa-tients with gastric cancer radical surgery,and the corresponding area under the curve(AUC)was calculated,and the predictive value of inflammatory indicator C-reactive protein(CRP)addition on GLIM criteria in pre-dicting the prognosis of the patients with gastric cancer radical surgery was evaluated.Results Malnutrition diagnosed by GLIM criteria was an independent risk factor affecting the postoperative survival rate of the pa-tients with gastric cancer radical surgery.The results of survival trend analysis of various indicators in GLIM criteria showed that involuntary weight reduction(moderate malnutrition HR=14.13,95％CI:1.70-117.39,severe malnutrition HR=12.50,95％CI:1.40-111.89)and CRP＞10 mg/L(HR=9.70,95％CI:2.31-40.67)were the most important factors affecting the survival rate of the patients with gastric cancer radical surgery.In addition,the addition of inflammatory marker CRP could increase the sensitivity and speci-ficity of the GLIM model in predicting the postoperative survival rate of the patients with gastric cancer radical sur-gery.Conclusion The GLIM criteria can not only reflect the nutritional status of the patients with gastric cancer radi-cal surgery,but also serve as an effective predictive tool for predicting the survival rate after radical surgery.The addition of inflammatory marker CRP increases the sensitivity and specificity of GLIM criteria in predicting postoperative survival rate.
