Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients

Objective：To validate malnutrition screening tool of nutrition risk index （NRI） against patent-generated subjective global assessment （PG-SGA） as a gold standard tool in colorectal cancer patients before radiotherapy.Methods：Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA （gold standard method） and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results：The findings of PG-SGA and NRI showed that 52％ and 45％ of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66％ and a specificity of 60％ against PG-SGA.The positive predictive value was 64％ and the negative predicative value was 62％.The agreement between NRI and PG-SGA was statistically insignificant （kappa =0.267; P＞0.05）.Conclusions：The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients.

Validity of the Patient-Generated Subjective Global Assessment(PG SGA)in Colorectal Cancer Patients in China

Objective The patient-generated subjective global assessment(PG-SGA)is a nutritional assessment tool specially designed for cancer patients.This study tested the validity of the PG-SGA for the nutritional assessment of colorectal cancer(CRC)patients in China.Methods A total of 8,093 Chinese patients with any stage CRC were enrolled in this cross-sectional,observational study.Within the first 48 hours of admission,patients were evaluated using the PG-SGA,nutritional risk screening 2002(NRS 2002),Karnofsky Performance Status(KPS),and some anthropometric parameters,including the triceps skinfold thickness(TSF),mid-arm circumference(MAC),mid-arm muscle circumference(MAMC),hand grip strength(HGS),maximum left calf circumference(MLCC),and maximum right calf circumference(MRCC),among others.Spearman’s correlation test was performed to analyze item-total score correlations and correlations between the total PG-SGA score and other parameters or performance scores,further testing convergent validity.The discriminative ability of the PG-SGA was measured by comparing different characteristics between several nutritional groups.A principal component analysis was performed with selected parameters to evaluate the construct validity.Results The average total PG-SGA score of all patients was 5.69±4.46,and they had a median age of 59 years(interquartile range(IQR),51-67 years)and an average body mass index(BMI)of 22.57±3.29 kg/m^(2).The item-total correlations of the total PG-SGA score between the global PG-SGA rating(Spearman,r=0.94)and PG-SGA score(patient-generated)(Spearman,r=0.97)were strong.Significant correlations were also found between the total PG-SGA score and other nutritional screening tools,including the BMI(Spearman,r=-0.26),KPS(Spearman,r=-0.36),and NRS 2002(Spearman,r=-0.47).Well-nourished(41.2%),mildly or moderately malnourished(35.3%)and severely malnourished(23.5%)groups defined according to the PG-SGA had significantly different characteristics.Patients with a worse nutritional status tended to have a decreased BMI(well-nourished,23.32 kg/m^(2)vs.mildly or moderately malnourished,22.52 kg/m^(2)vs.severely malnourished,21.35 kg/m^(2);P<0.001),hemoglobin,body fat mass,muscle mass,protein mass,TSF,MAC,HGS,MAMC,and MLCC,and a dramatically increased C-reactive protein level.The Kaiser-Meyer-Olkin measure was>0.7,and the P value of Bartlett’s test of sphericity was<0.001.One component was extracted by the principal component analysis,and the analysis showed that the total PG-SGA score explained the total variances of 97.3%.Conclusion The PG-SGA is a valid tool for evaluating the nutritional status for Chinese CRC patients.

Subjective Global Assessment as a Pre-Operative Nutrition Status Screening Tool for Head and Neck Cancer Patients of a Tertiary Health Care Setting

Introduction: In India, 57% of patients with head and neck cancers are documented with nutritional compromise. Active nutritional support has been shown to improve outcomes and reduce the cost of treatment in severely malnourished patients. The assessment of nutritional status should be a priority when initiating medical nutrition therapy. We evaluated the agreement between Subjective and Objective evaluation of pre-operative nutrition status of head and neck cancer patients in a tertiary cancer centre. Methods: Two hundred and thirty seven head and neck cancer patients who underwent surgery were eligible. The patients included both males (147) and females (90) with age varying between 23 - 88 years. All patients were screened for pre-operative nutrition status objectively as well as subjectively. The association of pre-operative SGA scores (A, B and C) subjectively, and PNS score (0, 1, 2) objectively were tested for statistical significance. Results: The cancer sites included tongue in 82, buccal mucosa in 30, thyroid in 28, alveolus in 18, glottis in 10, RMT in 10, nasal cavity in 9, FOM in 8. The pre-operative nutrition status based on subjective scores are A in 156 (65.8%), B in 75 (32%) and C in 6 (2.5%). The objective parameters obtained on the basis of BMI, % weight loss, PNI and S. albumin values are PNS 0 in 161 (67.9%), PNS 1 in 71 (30%) and PNS 2 in 5 (2.1%) patients. As the kappa coefficient p-0.56, there is moderate agreement between the pre-operative nutrition status subjectively as well as objectively. Conclusion: Subjective global assessment is a simple and inexpensive way to screen the pre-operative nutrition status when compared to the other objective assessment tool. SGA has moderate agreement with expensive and complicated objective assessment tools. So it can be a reliable tool for assessing the pre-operative nutrition status.

Comparison of different nutritional assessments in detecting malnutrition among gastric cancer patients

AIM: To evaluate the prevalence of preoperative and postoperative malnutrition and the relationships between objective and subjective nutritional assessment of gastric cancer patients. METHODS: From October 2005 to July 2006, we studied 80 patients with no evidence of recurrent disease and no loss to follow-up after curative surgery for gastric cancer. In this group, 9 patients underwent total gastrectomy and 71 patients subtotal gastrectomy. At admission, 6 and 12 mo after surgery, the patients were assessed on the subjective global assessment (SGA), nutritional risk screening (NRS-2002), nutritional risk index (NRI) and by anthropometric measurements and laboratory data. Differences between the independent groups were assessed with the Student's t test and oneway analysis of variance. Spearman's rank correlation coefficients were calculated to evaluate the association between the scores and variables. RESULTS: The prevalence of malnutrition at admissionwas 31% by SGA and 43% by NRS-2002. At admission, the anthropometric data were lower in the malnourished groups defined by the SGA and NRS-2002 assessments, but did not differ between the groups using the NRI assessment. Body weight (BW), body mass index (BMI), triceps skin fold and midarm circumference were significantly reduced, but the total lymphocyte count, albumin, protein, cholesterol and serum iron levels did not decrease during the postoperative period. Six months after surgery, there was a good correlation between the nutritional assessment tools (SGA and NRS-2002) and the other nutritional measurement tools (BW, BMI, and anthropometric measurements). However, 12 mo after surgery, most patients who were assessed as malnourished by SGA and NRS-2002 had returned to their preoperative status, although their BW, BMI, and anthropometric measurements still indicated a malnourished status. CONCLUSION: A combination of objective and subjective assessments is needed for the early detection of the nutritional status in case of gastric cancer patients after gastrectomy.

Nutritional assessment with different tools in leukemia patients after hematopoietic stem cell transplantation

Objective： Correct nutritional assessment is essential for leukemia patients after hematopoietic stem cell transplantation （HSCT）. This study aimed to investigate the best nutritional assessment method for leukemia patients after HSCT, and find the possible nutritional risk of the patients during the transplantation process in order to intervene in the patients with nutritional risks and undernourished patients timely, so that the entire transplantation process could be successfully completed. Methods： A prospective study was performed in 108 leukemia patients after HSCT, and different nutritional assessment methods, including nutritional risk screening 2002 （NRS2002）, mini nutritional assessment （MNA）, subjective globe assessment （SGA） and malnutritional universal screening tools （MUST）, were used. The associations between nutritional status of these patients and nutritional assessment methods were analyzed. Results： A total of 108 patients completed SGA, and 99 patients completed NRS2002, MNA and MUST. During the treatment process, 85.2% of the patients lost weight, wherein, 50% lost weight greater than 5%, and 42.6% had significantly reduced food intake. For nutritional risk assessment, the positive rates of NRS2002, MNA and MUST were 100%, 74.7% and 63.6%, respectively. There was a significant difference （P〈0.05） among the positive rates of NRS2002, MNA and MUST. In undernutrition assessment, the positive rate of SGA （83.3%） was significantly higher than that of MNA （17.2%） （P〈0.05）, and the incidence rate of nutritional risk among leukemia patients _〈30 years old was greater than that of patients 〉30 years old （P〈0.05）. Conclusions： Patients with leukemia were in poor nutritional status during and after HSCT. The leukemia patients 〈30 years old had a greater incidence rate of nutritional risk. As nutritional risk screening tool, the specificity of NRS2002 is not high, but it can be used for evaluating nutritional deficiencies. MNA is a good nutritional risk screening tool, but not an adequate tool for nutritional assessment. If assessment of undernutrition is necessary, the combination of all these screening tools and clinical laboratory indicators should he applied to improve accuracy.

Comparison of two nutritional assessment methods in gastroenterology patients

AIM:To investigate and compare efficacy and differences in the nutritional status evaluation of gastroenterology patients by application of two methods:subjective global assessment(SGA) and nutritional risk index(NRI).METHODS:The investigation was performed on 299 hospitalized patients,aged 18-84 years(average life span 55.57 ± 12.84),with different gastrointe-stinal pathology,admitted to the Department of Gastroenterohepatology,Clinical and Hospital Center "Bezanijska Kosa" during a period of 180 d.All the patients,after being informed in detail about the study and signing a written consent,underwent nutritional status analysis,which included two different nutritional indices:SGA and NRI,anthropometric parameters,bioelectrical impedance analysis,and biochemical markers,within 24 h of admission.RESULTS:In our sample of 299 hospitalized patients,global malnutrition prevalence upon admission varied from 45.7% as assessed by the SGA to 63.9% by NRI.Two applied methods required different parameters for an adequate approach:glucose level(5.68 ± 1.06 mmol/L vs 4.83 ± 1.14 mmol/L,F = 10.63,P = 0.001);body mass index(26.03 ± 4.53 kg/m2 vs 18.17 ± 1.52 kg/m2,F = 58.36,P < 0.001);total body water(42.62 ± 7.98 kg vs 36.22 ± 9.32 kg,F = 7.95,P = 0.005);basal metabolic rate(1625.14 ± 304.91 kcal vs 1344.62 ± 219.08 kcal,F = 9.06,P = 0.003) were very important for SGA,and lymphocyte count was relevant for NRI:25.56% ± 8.94% vs 21.77% ± 10.08%,F = 11.55,P = 0.001.The number of malnourished patients rose with the length of hospital stay according to both nutritional indices.The discriminative function analysis(DFA) delineated the following parameters as important for prediction of nutritional status according to SGA assessment:concentration of albumins,level of proteins,SGA score and body weight.The DFA extracted MAMC,glucose level and NRI scores were variables of importance for the prediction of whether admitted patients would be classif ied as well or malnourished.CONCLUSION:SGA showed higher sensitivity to predictor factors.Assessment of nutritional status requires a multidimensional approach,which includes different clinical indices and various nutritional param eters.

Clinical application of subjective global assessment in Chinese patients with gastrointestinal cancer

AIM:To investigate the role of subjective global assessment(SGA) in nutritional assessment and outcome prediction of Chinese patients with gastro-intestinal cancer.METHODS:A total of 751 patients diagnosed with gastrointestinal cancer between August 2004 and August 2006 were enrolled in this study.Within 72 h after admission, SGA, anthropometric parameters, and laboratory tests were used to assess the nutritional status of each patient.The outcome variables including hospital stay, complications, and in-hospital medical expenditure were also obtained.RESULTS:Based on the results of SGA, 389(51.8%), 332(44.2%), and 30(4.0%) patients were classified into well nourished group(SGA-A), mildly to moderately malnourished group(SGA-B), and severely malnourished group(SGA-C), respectively.The prevalence of malnutrition classif ied by SGA, triceps skinfold thickness(TSF), mid-upper arm muscle circumference(MAMC), albumin(ALB), prealbumin(PA), and body mass index(BMI) was 48.2%, 39.4%, 37.7%, 31.3%, 21.7%, and 9.6%, respectively.In addition, ANOVA tests revealed significant differences in body mass index(BMI), TSF, PA, and ALB of patients in different SGA groups.The more severely malnourished the patient was, the lower the levels of BMI, TSF, PA, and ALB were(P < 0.05).χ2 tests showed a significant difference in SGA classif ication between patients receiving different types of treatment(surgery vs chemotherapy/radiotherapy).As the nutritional status classif ied by SGA deteriorated, the patients stayed longer in hospital and their medical expenditures increased significantly.Furthermore, multiple regression analysis showed that SGA and serum ALB could help predict the medical expenditures and hospital stay of patients undergoing surgery.The occurrence of complications increased in parallel with the increasing grade of SGA, and was the highest in the SGA-C group(23.3%) and the lowest in the SGA-A group(16.8%).CONCLUSION:SGA is a reliable assessment tool and helps to predict the hospital stay and medical expenditures of Chinese surgical gastrointestinal cancer patients.

The Role of the PNI and NLR in Nutritional Risk Screening and Assessment of Gastric Cancer Patients

Background The use of nutritional risk screening and assessment is becoming increasingly common in cancer patients.The Nutritional Risk Screening 2002(NRS 2002)is a nutritional risk screening programe with good utility.The patient generated-subjective global assessment(PG-SGA)is a method used to assess the nutritional status of cancer patients.The prognostic nutritional index(PNI)and neutrophil to lymphocyte ratio(NLR)are considered to be predictors of the prognosis following treatment for patients with a variety of cancers.However,the relationship between the PNI and NLR in the nutritional screening and assessment in patients with gastric cancer is unknown.Methods A retrospective analysis was performed on 378 patients with gastric cancer who underwent surgery at the First Affiliated Hospital of Guangxi Medical University from August 2019 to December 2020.NRS 2002 and PG-SGA were performed within 24 hours of admission,and indicators such as the serum albumin level,body mass index(BMI),PNI and NLR were measured.Results In the grouping based on the NRS2002,patients in the positive group(NRS 2002≥3)had a higher platelet value,a higher median NLR,and a lower PNI than those in the negative group(NRS 2002<3)(295.50±118.49×10^(9)/L vs.269.36±93.52×10^(9)/L,2.38 vs.1.77,42.36±5.96 vs.46.64±4.29).Based on the PG-SGA grouping,the serum albumin level and lymphocyte count were highest in the mild group(PG-SGA:score 2-3),(36.94±3.51 g/L and 1.91±0.7610^(9)/L)and lowest within the severe group(PG SGA score≥9)(34.09±4.18 g/L and 1.51±0.6410^(9)/L).The BMI was highest in the mild group(23.35±3.00 kg/m^(2))and lowest in the severe group(20.63±2.97 kg/m^(2)),and the PNI was also highest in the mild group(46.50±5.17)and lowest in the severe group(41.64±5.53).However,the NLR was lowest in the mild group(median 1.91)and highest in the severe group(median 2.44).Conclusion The PNI and NLR in gastric cancer patients are closely related to the results of the nutritional risk screening and assessment,suggesting that they may be useful to guide the nutritional interventions for gastric cancer patients.

Nutritional Assessment of Gynecological Cancer Patients in China

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.

Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects

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.

Preliminary validation of Global Leadership Initiative on Malnutrition criteria in cancer patients:A cross-sectional study

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.

Extension Protocol for the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC)Study:2021 update

Background Malnutrition is common in patients with cancer,and this adversely affects the survival and quality of life of patients.Chinese Society for Nutritional Oncology issued a multi-center,large-scale,long-term follow-up prospective study,the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC study)since 2013.This is an extension to the previous 2013-2020 study protocol.This study still sought to:①address the prognostic impact of nutritional factors and quality of life on cancer patient survival;②describe the overall and cancer-specific incidence and/or distribution of malnutrition and different measurements of patient quality of life.Methods and study design This is an observational,multi-centered,hospital-based prospective cohort study.Data collection will be performed at baseline(within 48 hours after patient admission),during the hospital stay and 30 days after hospital admission.Follow-up will be conducted for 1-20 years after enrollment.The primary outcome will be the all-cause mortality/overall survival,and secondary outcomes will be the length of hospital stay and costs of hospitalization.Study factors will include demographic characteristics,tumor characteristics,information about chronic diseases,hematological measurements(e.g.,red blood cell count,total lymphocyte counts,hemoglobin,albumin,prealbumin,creatinine,C-reactive protein,IL-6),anthropometric measurements(e.g.,height,weight,arm circumference,arm muscle circumference,triceps skinfold thickness,and waist circumference),body composition parameters,PG-SGA scores,quality of life(as indicated by the QLQ-C30 questionnaire),muscle mass(as indicated by the calf circumference),muscle strength(as indicated by the handgrip strength),muscle function(as indicated by the six-meter walking speed test)and physical status assessments(as indicated by the Karnofsky Performance Status scores).This clinical study protocol was approved by local Ethics Committees of all the participating hospitals.Written informed consent is required for each subject included.Discussion This multi-center,large-scale,long-term follow up prospective study will help improve the diagnosis of malnutrition in cancer patients and identify the risk factors associated with adverse clinical outcomes.The anticipated results of this study will highlight the need for a truly scientific appraisal of nutrition therapy in Chinese oncology populations,and finally help treat the potentially reversible elements of malnutrition in cancer patients to improve their clinical outcomes in the future.

Nutritional Support During Chemotherapy in a Patient with Advanced Gastric Cancer: A Case Report

Gastric cancer (GC) is one of the most common malignancies in China. GC patients often present with dysphagia and abnormal digestive function, leading to malnutrition or even cachexia. In February 2017, an advanced GC patient at Peking University Cancer Hospital received chemotherapy with the additional support of nutritional treatment. After being treated with the dietary prescription and oral nutritional supplements, the patient’s malnutrition was reversed, and he was able to complete five full cycles of chemotherapy.

Malnutrition as a predictor of prolonged length of hospital stay in patients with gynecologic malignancy: A comparative analysis

Objective To explore the consistency of the Patient-generated Subjective Global Assessment(PG-SGA)and Nutritional Risk Screening-2002(NRS-2002)for nutritional evaluation of patients with gynecologic malignancy and their predictive effect on the length of hospital stay(LOS).Methods We recruited 147 hospitalized patients with gynecologic malignancy from Nanfang Hospital in 2017.Their nutritional status was assessed using the PG-SGA and NRS-2002.The consistency between the two assessments was compared via the Kappa test.The relationship between malnutrition and LOS was analyzed using crosstabs and Spearman’s correlation.Results The PG-SGA demonstrated that 66.7%and 54.4%of patients scoring≥2 and≥4 were malnourished,respectively.Furthermore,the NRS-2002 indicated that 55.8%of patients were at nutritional risk.Patients with ovarian cancer had a relatively high incidence of malnutrition.However,this was only significant for patients who scored≥4 in the PG-SGA(P=0.001 and P=0.019 for endometrial carcinoma and cervical cancer,respectively).The PG-SGA and NRS-2002 showed good consistency in evaluating the nutritional status of patients with gynecologic malignancy(0.689,0.643 for PG-SGA score≥2,score≥4 and NRS-2002,respectively).Both the scores of PG-SGA and NRS-2002 were positively correlated with LOS.Furthermore,prolonged LOS was higher in patients with malnutrition than in those with adequate nutrition.Conclusion The PG-SGA and NRS-2002 shared a good consistency in evaluating the nutritional status of patients with gynecologic malignancy.Both assessments could be used as predictors of LOS.

Nutritional Screening in a University Hospital:Comparison between Oncologic and Non-Oncologic Patients

Background & Aims: We compared the screening nutritional data of patients with malignant and non-malignant disease, and classified their nutritional risk according to the primary tumor’s site. Methods: Subjective Global Assessment was applied to 3008 patients within 48 h of admission to a public university. Subjects were divided into Oncologic Group (n = 576) or Non-Oncologic Group (n = 2432) according to the presence of neoplasms or other diseases respectively. These data were compared by the t-student test and classic chi-square test, with statistical significance set at p < 0.05. Results: The Oncologic Group presented a higher prevalence of weight loss (60.3% vs. 49.3%), quantitative (40.7% vs. 28.5%) and qualitative (16.4% vs. 7.6%) alterations in the food intake pattern, gastrointestinal symptoms and muscle waste (23.2% vs. 13.2%) as compared to the Non-Oncologic Group. Also, there was a higher prevalence of nutritional disturbances in the Oncologic Group, with 49.5% of the subjects moderately (or suspected to be malnourished) and 12.7% severely mal-nourished. Severe malnourishment was mainly observed in patients with head and neck (25%), upper digestive tract (21.9%) and soft tissue and bones (17.9%) tumors.
