Investigation on nutrition status and clinical outcome of patients with common cancers in Chinese patients: a multicenter prospective study protocol

Background:Malnutrition is common in patients with cancer, whichadversely affectsthesurvival and quality of life ofcancer patients.However, there is no national data on the prevalence of malnutrition inChinese cancer patients. Thisstudy aims to evaluate the prevalenceof malnutrition and quality of life(QOL)ofChinese patients with localregional, recurrentor metastatic cancer,to address the prognostic value of nutritional status and QOLon the survival of cancer patients in China and to validate the patient-generated subjective global assessment (PG-SGA) questionnaire in Chinese cancer patients.Methods:Thisisanobservational,multi-centered,and hospital-based prospective cohort study.We aimed to recruit 50,000 cancer patients (age 18and above)overan 8-year period.Data collection will occur within 48hrafter patientsare admitted to hospital, 30-days after hospital admission, and the follow-up will be conducted1-8years after enrolment. The primary outcomeisoverall survival, and secondaryoutcomes arelength of hospital stay and hospital costs. Factors measured are demographic characteristics, tumor characteristics, anthropometry measurements,hematological measurement, body composition, PG-SGAscores,Karnofsky performance status scores,and QLQ C30 scores. This protocol wasapproved by local ethical committees of all the participant hospitals.Conclusions: This multi-centered, large-scale, long-time follow-up prospective study will help diagnose malnutrition in cancer patients in China, and identify the related risk factors associated with the negative outcomes. The anticipated results will highlight the need for a truly scientific appraisal of nutrition therapy, and help to improve outcomes among cancer patients in China.Trial Registration: The trial has been registered with the Chinese Clinical Trial Registry, ChiCTR1800020329.

Comparative study of prognostic nutritional index and patient-generated subjective global assessment in perioperative nutritional prediction in patients with esophageal cancer / 中国胸心血管外科临床杂志

@#Objective    To investigate the prognostic value and consistency of prognostic nutritional index (PNI) and patient-generated subjective global assessment (PG-SGA) in perioperative nutritional status of patients with esophageal cancer. Methods    Clinical data of 224 patients, including 186 males and 38 females with an average age of 63.08±8.42 years, who underwent esophageal cancer surgery in our hospital from November 2017 to August 2018 were retrospectively reviewed. The PNI was calculated according to the results of the first time blood and biochemical tests, and the PG-SGA assessment was also performed. According to the PNI value, the patients were divided into a good nutrition group (PNI≥45, 60 patients) and a malnutrition group (PNI<45, 164 patients). According to the PG-SGA score, the patients were divided into a good nutrition group (PG-SGA<4, 75 patients) and a malnutrition group (PG-SGA≥4, 149 patients). Nutrition-related haematological indexes and body mass index (BMI) were compared between the two groups, and the consistency of PNI and PG-SGA for nutritional assessment was analyzed. Results    The nutrition-related haematological indexes in different PNI groups were statistically different in the perioperative period (P<0.01). The longitudinal changes of prealbumin in patients of different PG-SGA groups were statistically different (P<0.05); the BMI of patients in different PG-SGA groups was statistically different in the perioperative period (P<0.01). The Kappa coefficient of the two indicators was 0.589 (P<0.001). Conclusion    Both PNI and PG-SGA can predict the nutritional risk of patients with esophageal cancer to some extent. PNI is an objective monitoring indicator, and PG-SGA is a subjective evaluation indicator, the combined use of which can more comprehensively reflect and predict the nutritional status of patients, and provide an important reference to the development of individualized nutrition support programs.

Prevalence of nutritional risk and malnutrition in hospitalized patients with different stages of lung cancer in a tertiary hospital in Chongqing: a cross-sectional survey / 中华临床营养杂志

Objective To investigate the prevalence of nutritional risk and malnutrition in hospitalized lung cancer patients in a tertiary A hospital in Chongqing.Methods From December 2013 to July 2017,2 735 consecutive lung cancer patients were admitted to the Department of Pneumology at Daping Hospital for planned anti-cancer treatment.Patients who did not complete a nutritional status assessment and who had repeated admission wcrc excluded from the study.The demographic and tumor characteristics were investigated in the 548 lung cancer inpatients who completed the study.The nutritional risk screening 2002 (NRS 2002) was used to evaluate the nutritional risk.The individual nutritional status was also evaluated using the patient-generated subjective global assessment (PG-SGA) questionnaire,anthropometry measurements and hematological measurements.The physical status was assessed by the Karnofsky performance status (KPS).Results According to the NRS 2002 score,29.56％ (162/548) of the cancer patients had nutritional risk (score ≥3).The prevalence of nutritional risk was 17.39％,15.00％,22.00％ and 36.86％,respectively,for patients with stage Ⅰ,Ⅱ,Ⅲ and Ⅳ lung cancer.Forty-four patients (9.67％) had a body mass index＜ 18.5 kg/m2 and poor general condition,and the prevalence was 6.52％,5.00％,8.67％ and 11.22％,respectively,for stages I,Ⅱ,Ⅲ and Ⅳ.A total of 107 cases (19.53％) had impaired nutritional status (indicated by a severity score of 3 in the NRS 2002).The prevalence by different stages was 10.87％ (stage Ⅰ),5.00％ (stage Ⅱ),14.67％ (stage Ⅲ) and 25.00％ (stage Ⅳ).One hundred and twenty-five patients (22.81％) had PG-SGA scores ≥ 9,with 2.19％,2.50％,12.67％,and 33.33％ of patients in stages Ⅰ,Ⅱ,Ⅲ and Ⅳ having these high scores.The KPS scores were lower in the patients with nutritional risk and malnutrition than in the patients with a normal nutritional status.Conclusions The prevalence of nutritional risk and malnutrition in patients with lung cancer were mediom.Nutritional risk screening and nutritional status assessment should be considered at the time of admission for lung cancer patients in order to ensure better outcomes of treatment.

Investigation on Nutritional Status and Nutritional Intervention of Inpatients with Malignant Tumor in Our Hospital / 中国药房

OBJECTIVE:To provide reference for strengthening the rational nutritional intervention of patients with malignant tumor. METHODS:From Sept. 2016 to Oct. 2017,191 inpatients diagnosed as malignant tumor in our hospital were targeted. Nutritional support pharmacist used Nutritional Risk Screening 2002 (NRS 2002) and Patient-generated Subjective Global Assessment(PG-SGA)to conduct nutritional status assessment within 48 h of admission;at the same time,nutritional intervention for patients during hospitalization was investigated. RESULTS:Among 191 patients,NRS 2002 score ≥3 (with nutritional risk) was classified in 123 cases,and total incidence of nutritional risk was 64.40％. Totally 129 cases were classified into grade B and C(malnutrition)by PG-SGA,and total incidence of malnutrition was 67.54％. There was statistical significance in the incidence of malnutrition among patients aged below 60 years old and patients aged more than 60 years old(P<0.05). NRS 2002 and PG-SGA showed a consistency of Kappa=0.557 (P<0.001), with moderate consistency degree. Of 191 patients, only 46 received nutritional intervention(only 2 cases received total enteral nutrition),and the overall intervention rate was 24.08％. Among them, the intervention rate of patients with nutritional risk was only 34.15％(42/123), and the intervention rate of patients with malnutrition was 31.78％(41/129). CONCLUSIONS:The incidence of nutritional risk and malnutrition among patients with malignant tumors is high, especially in elderly patients. But clinical nutrition interventions are obviously inadequate and the application rate of enteral nutrition support is low. Therefore,nutritional support pharmacists are required to assist and cooperate with physicians,combined two tools as NRS 2002 and PG-SGA that can promptly and effectively screen patients who already have nutritional risk or malnutrition on admission and comprehensively evaluate their nutritional status, so as to give appropriate nutritional intervention.

La desnutrición es una complicación frecuente en pacientes con cáncer de cabeza y cuello (CyC). La Valoración Global Subjetiva Generada por el Paciente (VGS-GP)es una herramienta validada para valorar el estado nutricional. El objetivo del estudio fuedeterminar la frecuencia de desnutrición según VGS-GP en pacientes con cáncer de cabeza y cuello en el Instituto Nacional del Cáncer (INC) “Prof. Dr. Manuel Riveros” en el periodo 2014-2015.Estudioobservacional descriptivo de corte transversal en el que se estudiaron 81 pacientes mayores de 18 años, de ambos sexos condiagnóstico de cáncer de cabeza y cuello en el periodo 2014 - 2015. El estado nutricional de los pacientes fue valorado mediante la herramienta VGS-GP. La VGS-GP mostró una desnutrición moderada/severa del 64,2% (32,1% categorías B y 32,1%categorías C). El 98% de los pacientes presentó complicaciones secundarias, siendo la disfagia el síntoma más frecuente. Las "categorías B y C" se observaron con mayor frecuencia en pacientes del sexo masculino, de edades avanzadas, en estadiosIII/IV de la neoplasia, así como en pacientes sometidos a cirugía y quimioterapia ycon cáncer en faringe, cavidad oral y esófago proximal. Según la VGS-GPmás de la mitad de los pacientes con cáncer de cabeza y cuello presentaron desnutrición moderada o severa ("categorías B y C").

Malnutrition is a common complication in head and neck cancer patients. Scored Patient-Generated Subjective Global Assessment (EGS-GP) is a validated tool fornutritional evaluation in patients with cancer. To determine the frequency of malnutritionac cording to Scored-Patient-Generated Subjective Global Assessment (EGS-GP) inpatients with head and neck cancer at the National Cancer Institute “Prof. Dr. Manuel Riveros” from 2014-2015. It’s an observational descriptive cross-sectional study with primary data. A total of 81 patients of both sexes, over 18 years old with head and neck cancer were studied using the Patient-Generated Subjective Global Assessment during the evaluation period between 2014-2015. Scored-PG-SGA showed moderately/severe lymalnutrition with 64.2% ("class B and C" with 32.1% for each one). A high percentage of the patients display secondary symptoms (98%) and the dysphagia is the most common symptom observed. "Class B and C" were showed with more frequency in male patients, an advanced age, stages III/IV of the neoplasia, as in patients treated with surgery and chemotherapy and in patients with cancer in pharynx, oral cavity and proximal esophagus. According to Scored-Patient-Generated Subjective Global Assessment (EGSGP)more than half of head and neck cancer patients had moderate or severe malnutrition.

A preliminary investigation of body composition in prediction of malnutrition in patients with nasopharyngeal carcinoma / 中华放射肿瘤学杂志

Objective To investigate the relationship between nutritional status and quality of life ( QOL) in patients with nasopharyngeal carcinoma undergoing concurrent chemoradiotherapy, and to identify the optimal indices of body composition for evaluation of malnutrition. Methods Based on the European Society Parenteral and Enteral Nutrition ( ESPEN) consensus on the diagnosis of malnutrition and patient?generated subjective global assessment (PG?SGA), a prospective study was performed in 48 patients with nasopharyngeal carcinoma who received concurrent chemoradiotherapy in our hospital from 2014 to 2015. Changes in body composition and nutritional status were evaluated in those patients. The relationship between nutritional status and QOL was studied. The predictive factors for nutritional status in patients with nasopharyngeal carcinoma were explored. The correlation between datasets was evaluated by the Pearson correlation coefficient. The influencing factors for nutritional status were analyzed by Logistic regression. Results During concurrent chemoradiotherapy, some indices of body composition, including weight, body mass index ( BMI) , fat mass index ( FMI) , fat?free mass index ( FFMI) , body cell mass ( BCM) , skeletal muscle mass ( SM) , and phase angle ( PA) had different degrees of reduction ( P=0?00) , while the PG?SGA score gradually increased. The incidence of malnutrition in patients with nasopharyngeal carcinoma during radiotherapy was 2?1%?39?6% based on 2015 ESPEN consensus on the diagnosis of malnutrition and 12?5%?41?7% based on PG?SGA. These two methods showed good agreement at the fourth and sixth weeks of radiotherapy ( Kappa=0?911;Kappa=0?957) . The changes in QOL score were correlated with changes in FFMI and weight during radiotherapy ( r= 0?805, P= 0?00;r= 0?777, P= 0?00 ) . Logistic regression indicated that age, FMI, and FFMI were influencing factors for nutritional status ( P= 0?035, 0?013, 0?043) . Conclusions Patients with nasopharyngeal carcinoma have substantial nutritional deterioration during chemoradiotherapy. The nutritional status is closely associated with QOL. A prediction model of nutritional status can provide a comprehensive and accurate judgment of nutritional status in patients.

Correlation of the nutritional status with liver function and clinical outcomes in surgically treated liver cancer patients / 中华临床营养杂志

Objective To investigate the relationship of the nutritional status with liver function and clinical outcomes of liver cancer patients treated with surgery.Methods Altogether 112 hospitalized patients undergoing surgical treatments for liver cancer were enrolled from October 2011 to October 2013.Their general clinical data were collected,including creatinine-height index (CHI),arm circumference,grip strenghth,albumin,prealbumin,and transferrin.The nutritional status was assessed using Patient-Generated Subjective Global Assessment (PG-SGA).The liver function was assessed with Child-Pugh classification.Postoperative infectious complications and the hospital stays were recorded to assess the clinical outcomes.The correlation between nutritional status and liver function,and that between nutritional status and clinical outcomes were analyzed.Results Among the 112 patients,70 (62.5％) were in normal nutritional status,34 (30.4％) were with moderate malnutrition,and 8 (7.1％) were with severe malnutrition according to PG-SGA scores.PG-SGA assessment showed strong consistence with CHI nutritional assessment (κ =0.760,P =0.000),and moderate consistence with arm circumference assessment (κ =0.564,P =0.000),and grip strength assessment (κ =0.523,P =0.000).The live function classified by Child-Pugh was found highly correlated with PG-SGA assessment (rs =0.829,P =0.000).Postoperative infectious complications and hospital stays were both positively correlated with PG-SGA assessment (r =0.349,P =0.000 ; r =0.624,P =0.000).Conclusions PD-SGA combining with CHI can be used for the nutritional status assessment of liver cancer patients undergoing surgical treatments.The nutritional status of the patients has positive correlation with live function,infectious complications,and postoperative hospital stays.

A Prospective Observational Study Evaluating the Change of Nutritional Status and the Incidence of Dumping Syndrome after Gastrectomy

PURPOSE: The aim of this study was to investigate the change of nutritional status and the incidence of dumping syndrome after gastrectomy for gastric cancer. METHODS: From January 2013 to May 2014, 36 patients who underwent gastrectomy for gastric cancer were prospectively investigated in terms of nutritional status by body weight, anthropometric measurements, biochemical data, and Patient-Generated Subjective Global Assessment (PG-SGA). Dumping syndrome was assessed using a newly developed questionnaire based on the Japanese Society of Gastroenterological Surgery survey and Sigstad's scoring system. RESULTS: Body weight losses were 4.6%, 8.1%, and 6.9% at discharge, six months, and one year after discharge, respectively. Triceps skinfold thickness had no significance, however, mid-arm muscle circumference showed significant loss after gastrectomy. A part of the biochemical data showed significant change after gastrectomy, but almost indicated a restoring tendency within two months after discharge. In terms of PG-SGA, 33 patients (91.7%) were classified as A (well-nourished) before surgery, however, the number of well-nourished patients showed a sharp decrease to 1 (2.8%) at two weeks after discharge, and then gradually increased to 25 (69.4%) at one year. The main obstacles against diet intake were reported as 'early satiety' and 'anxiety'. The number of patients who had experience in at least one dumping syndrome related symptom was 21 (58.3%) at discharge, 26 (72.2%) at two months after discharge, and 11 (30.6%) at one year after discharge. CONCLUSION: Nutritional deficit as well as dumping syndrome is encountered in a large number of gastric cancer patients after gastrectomy. Postoperative nutritional support and personalized education seem to be very important during the postoperative period.

Investigation on the nutrition status of 132 advanced lung cancer patients in primary treatment / 肿瘤

Objective: To investigate the nutrition status of lung cancer patients in stage III and IV who were admitted in hospital and receive primary treatment. Methods: One hundred and thirty two lung cancer patients and 38 benign lung disease patients were prospectively investigated using patient generated-subjective global assessment (PG-SGA). Body mass index (BMI), total lymphocyte count, hemoglobin, serum albumin, iron transferring protein, pre-albumin, LDH, fasting glucose, cholesterol, triglycerides, blood urea nitrogen and creatinine levels were detected. Results: There were 19(14%) lung cancer patients in grade A, 51(39%) in grade B and 60(47%) in grade C based on PG-SGA score. Seventy two patients (54.5%) had PG-SGA score at 2 to 8 and 57 (42.2%) lung cancer patients had PG-SGA score ≥9, and only 3(2.3%) lung cancer patients had PG-SGA score between 0 to 1. The ratio of lung cancer patients in grade C was significantly higher than benign lung disease patients. In lung cancer patients at stage III and IV, BMI and serum albumin were significantly different between A, B and C 3 grades; age of patients and hemoglobin level were significantly different between B and C 2 grades. The chemotherapy-induced bone marrow suppression correlated with the number of combined drugs. Conclusion: The admitted lung cancer patients at stage III and IV had high protein-energy malnutrition rates. There was good consistency between PG-SGA score and traditional nutritional assessment indicated by BMI, serum albumin, and hemoglobin.
