Methods:A total of 2,000 cancer patients were consecutively screened using the Nutritional Risk Screening 2002 instrument on ad-mission.Patients at nutritional risk(Nutritional Risk Screening 2002 score≥3)were enrolled to obtain the complete GLIM,PG-SGA,and mPG-SGA criteria.To evaluate the convergent validity,Spearman correlation analysis was used to compare the test-retest reliability of the GLIM criteria and its results with the scores of various nutritional tools and objective parameters.Kruskal-Wallis tests and χ2 tests were used to test the discriminant validity among groups with different nutritional status.We calculated the sensitivity,specificity,positive predictive value,and negative predictive value for the various tools. Results:There were 562 patients found to be at nutritional risk,accounting for 28.1%of all patients.One hundred seventy-four patients(8.7%)were diagnosed as moderately malnourished,and 333 patients(16.6%)were severely malnourished based on the PG-SGA.When assessed using the GLIM criteria,185 patients(9.3%)were diagnosed as moderately malnourished and 311 patients(15.5%)were severely malnourished.The content validity of the GLIM criteria was 95%,evaluated by 60 medical staff members.The test-retest reliability was good.For the diagnosis of malnutrition versus the PG-SGA,the sensitivity of the GLIM was"good"(90.5%;95%confidence interval[95%CI]=88.0%-93.1%),with a positive predictive value of 92.5%(95%CI=90.2%-94.9%),but the spec-ificity and negative predictive value were"poor."Similar results were obtained when the mPG-SGA was used as the criterion. Conclusions:Overall,this cross-sectional study suggests that the GLIM criteria comprise a valid and reliable tool to assess the nutri-tional status of Chinese cancer patients.展开更多

文摘Background Malnutrition is common among cancer patients,but few studies have evaluated the nutritional status among gynecological cancer patients in China.This study aimed to assess the nutritional status of women with gynecological cancer using the patient-generated subjective global assessment(PG-SGA).Methods Data for gynecological cancer patients treated at 44 tertiary hospitals were retrieved from a multicenter study on tumor nutrition.The R Software was used for statistical analyses.Univariate analyses of PG-SGA scores were performed using the Chi-squared test for categorical variables and the Wilcoxon-rank sum test or Kruskal-Wallis test for continuous variables,as appropriate.The significance level was 0.05.Results Data for 1962 women with three types of gynecological cancer(cervical,uterine and ovarian cancer)were used for the data analysis.The median PG-SGA score was 4(interquartile range,IQR:1,8),the median participants’age was 51(IQR:46,59)years old,and the patients had a median BMI of 22.9(IQR:20.7,25.4).The percentages of women who had a medical co-morbidity,or had undergone any radical resection,chemotherapy,or radiotherapy were approximately 27.7%,55.4%,52.5%,and 30.2%,respectively.The levels of serum albumin and high density lipoprotein cholesterol(HDL-C)were 40.1g/L(IQR:36.8,43.1)and 1.2mmol/L(IQR:1.0,1.5),respectively.The identified risk factors for malnutrition based on the PG-SGA score were age(0.05±0.01,p=0.002),BMI(-0.34±0.04,p<0.001),having a medical co-morbidity(0.95±0.33,p=0.004),receiving radiotherapy(1.52±0.31,p<0.001),the serum albumin level(-0.18±0.03,p<0.001),and the HDL-C(-1.12±0.35,p=0.001)as indicated by a linear regression analysis.Conclusions A higher PG-SGA score is positively associated with the age of the patient,having a medical co-morbidity,and receiving radiotherapy,and is negatively related to the patients’BMI and serum albumin and HDL-C levels.
文摘Background:The Global Leadership Initiative on Malnutrition(GLIM)has been used in China since 2019.This study aimed to test the use of the GLIM criteria in Chinese cancer patients and to compare the diagnostic performance of the GLIM criteria with the Patient-Generated Subjective Global Assessment(PG-SGA)and modified PG-SGA(mPG-SGA). Methods:A total of 2,000 cancer patients were consecutively screened using the Nutritional Risk Screening 2002 instrument on ad-mission.Patients at nutritional risk(Nutritional Risk Screening 2002 score≥3)were enrolled to obtain the complete GLIM,PG-SGA,and mPG-SGA criteria.To evaluate the convergent validity,Spearman correlation analysis was used to compare the test-retest reliability of the GLIM criteria and its results with the scores of various nutritional tools and objective parameters.Kruskal-Wallis tests and χ2 tests were used to test the discriminant validity among groups with different nutritional status.We calculated the sensitivity,specificity,positive predictive value,and negative predictive value for the various tools. Results:There were 562 patients found to be at nutritional risk,accounting for 28.1%of all patients.One hundred seventy-four patients(8.7%)were diagnosed as moderately malnourished,and 333 patients(16.6%)were severely malnourished based on the PG-SGA.When assessed using the GLIM criteria,185 patients(9.3%)were diagnosed as moderately malnourished and 311 patients(15.5%)were severely malnourished.The content validity of the GLIM criteria was 95%,evaluated by 60 medical staff members.The test-retest reliability was good.For the diagnosis of malnutrition versus the PG-SGA,the sensitivity of the GLIM was"good"(90.5%;95%confidence interval[95%CI]=88.0%-93.1%),with a positive predictive value of 92.5%(95%CI=90.2%-94.9%),but the spec-ificity and negative predictive value were"poor."Similar results were obtained when the mPG-SGA was used as the criterion. Conclusions:Overall,this cross-sectional study suggests that the GLIM criteria comprise a valid and reliable tool to assess the nutri-tional status of Chinese cancer patients.

文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2<BMI<24 kg/m2),overweight(24 kg/m2≤BMI<28 kg/m2)and obese(BMI≥28 kg/m2)were 9.3%,59.9%,26.1%and 4.7%,respectively.A total of 18.3%(4,101/22,424)of patients had lost 5%or more of their bodyweight within the past month and 19.6%(2,463/12,538)of patients had lost 10%or more of their bodyweight within the past 6 months.According to the PG-SGA scores,26.6%of the patients were severely malnourished(score≥9),31.3%were moderately malnourished(scores 4~8).A total of 22.2%of patients had a serum albumin level lower than 35g/L.Only 8.6%(2056/23,991)of the patients had severe KPS scores(≤60).The patients with these severe KPS scores were most frequently among those with cancers of the brain(19.7%),prostate(18.0%),pancreas(15.5%)and bladder(15.0%).Based on the QLQ-C30 score,11.6%of patients had a poor QoL.The PG-SGA score and global QoL were correlated(r=-0.593,P<0.001).Conclusion The prevalence of malnutrition in patients with cancer is relatively high,and is related to a poorer QoL.The present findings should be kept in mind when assessing cancer patients,because addressing the patient’s problems in nutritional status would be expected to improve both the clinical outcomes and QoL in cancer patients with malnutrition.

文摘Objective To examine the utility of the Nutrition Risk Screening 2002(NRS 2002),Patient-Generated Subjective Global Assessment(PG-SGA)and serum factors for the preoperative evaluation of gastric cancer patients.Methods We examined 181 gastric cancer patients treated at the First Affiliated Hospital of Guangxi Medical University from January 2015 to January 2018.Nutritional assessments were administered within 48 h of admission.The body mass index(BMI)and serum factors were measured,and information on preoperative nutritional support and postoperative complications was recorded.Results Both the NRS 2002 and PG-SGA had positive correlations with age(P<0.05),and negative correlations with albumin,prealbumin,transferrin,hemoglobin,BMI,and bodyweight(P<0.05).The NRS 2002 and PG-SGA scores were positively correlated with each other(r=0.683,P<0.01),but had poor consistency(κ=0.357,P<0.01).During the preoperative period,33.2%of patients received nutritional support,mainly enteral nutrition.The nutritional risk group(NRS 2002≥3)received more support than the group without nutritional risk(NRS 2002<3;P<0.05).Patients with nutritional risk or malnutrition who received preoperative nutritional support had fewer postoperative complications than unsupported patients.The overall rate of complications was 12.2%,and the rate of severe complications(gradeⅢor above)was 5.5%.The malnutrition and nutritional risk groups had higher rates of severe complications.Conclusions The combined application of the NRS 2002,PG-SGA,BMI,and serum nutritional indices was useful for the nutritional screening and assessment of preoperative gastric cancer patients.The NRS 2002 and PG-SGA provided guidance on the need for nutritional support during the preoperative period.
文摘目的本研究的目的是研究不同的营养评估方法与维持性血液透析患者的预后的关系。方法对我院血液透析中心的83名患者进行营养评估,包括主观综合性营养评估(subjective global assessment,SGA)、营养不良-炎症评分(malnutrition inflammation score,MIS)和微型营养评定简表(mini nutrition assessment short form,MNA-SF)。同时收集基本资料、辅助检查结果。随访48月(40±13月),采用Kaplan-Meier以及Cox回归分析比较不同营养评估方法与患者全因死亡风险的差别。结果 Kaplan-Meier分析提示:SGA<25分患者的死亡风险较SGA≥25分患者高(P<0.05),MIS>10分组比MIS≤10分死亡风险高(P>0.05)。以MNA-SF分组,MNA-SF≥11分死亡风险低于NA-SF<11分(P>0.05)。多因素Cox回归分析提示,SGA及MIS不同分组仍然与维持性血液透析患者不同的全因死亡风险有关(P<0.05)。结论不同营养评估方法对于维持性血液透析患者长期生存的预测能力不同,SGA法以及MIS法所评价的营养状况与维持性血液透析患者长期的全因死亡风险有较好相关性。
