The Correlation Study Of NRS2002,PG-SGA,Clinical Nutritional Indicators And Pathological Stage Of Patients With Gastric Cancer

Objective :to study the correlation between patient age,plasma albumin,BMI,tumor size,tumor location,vascular infiltration,pathological staging NRS2002 and PG-SGA scores of patients.with gastric cancer To explore the impact of pathological staging of gastric cancer patients on nutritional risk and severity of malnutrition.Methods: 248 patients with gastric cancer who underwent surgical operations in our hospital from August 2019 to August 2020 were enrolled using consecutive samplingin this study.After 24 hours of admission,NRS2002 and PG-SGA were used to evaluate the nutritional status of the patient,and to measure the patient’s albumin(Alb),body mass index(BMI)and collect the pathological report content of the patient’s tumor size,tumor location,vascular infiltration,pathological staging.Results:1.The NRS2002 score with and without nutritional risk groups has statistical significance in age,albumin,BMI,tumor size,vascular infiltration,tumor location,and pathological stage(P<0.05),but no statistical significance in ethnicity and gender(P >0.05).Based on the above single-factor screening of the influencing factors,a multi-factor logistic regression analysis was performed.Plasma albumin and BMI are independent influencing factors of the nutritional risk of gastric cancer patients(p<0.05).Pathological staging is not an independent factor influencing the nutritional risk of gastric cancer patients(P>0.05).The PGSGA score was statistically significant in patient age,tumor size,plasma albumin,BMI,vascular infiltration,tumor location,and pathological stage(P<0.05);there was no statistical significance in ethnicity and gender(P> 0.05);Based on the above single-factor screening of the influencing factors,multivariate logistic regression analysis was performed,and PG-SGA was statistically significant in patient age,plasma albumin,BMI,tumor location,and pathological stage(P<0.05).The pathological stages of patients with stage 0,stage I,and stage II were significantly less likely to have moderate or severe malnutrition than those with stage IV(P<0.05).Patients whose tumor sites were in the cardia and gastric antrum were significantly more likely to have moderate or severe malnutrition than those whose tumor sites were in the gastric body(P<0.05).Age,plasma albumin and BMI are independent factors influencing the severity of malnutrition(P<0.05).Vascular infiltration and tumor size are not independent factors influencing the severity of malnutrition(P>0.05).PG-SGA and NRS2002 have poor nutritional consistency in patients with gastric cancer(Kappa=-0.04,P<0.01).Conclusion:1.Pathological staging is an independent risk factor for the severity of malnutrition,suggesting that patients with gastric cancer should be detected early and treated early 2.Patients whose tumors are located in the cardia and gastric antrum are more likely to have malnutrition and have a higher PGSGA score 3.Elderly patients with gastric cancer have higher PG-SGA scores and are more prone to malnutrition.4.The smaller the BMI and plasma albumin,the more likely gastric cancer patients are to have nutritional risks.Plasma albumin and BMI are independent factors influencing the severity of malnutrition.
