The Effect of Omega-3 Enriched Oral Nutrition Supplement on Nutritional Indices and Quality of Life in Gastrointestinal Cancer Patients: A Randomized Clinical Trial

Objective: Gastrointestinal (GI) cancer patients often experience severe malnutrition during cancer therapies due to gastrointestinal dysfunctions including poor digestion and absorption as well as tumor-associated anorexia. In this study, we performed a randomized clinical trial to determine the efficacy of oral nutrition supplement (ONS) enriched with omega-3 fatty acids on nutritional status, quality of life (QOL), and pro-inflammatory indices. Methods: Patients diagnosed with GI cancers were recruited and screened for eligibility. A total of 58 patients were randomly allocated to either the control group (n=27) or the experimental group (n=31). The intervention group received 200 ml ONS twice a day while the control group received routine care. Anthropometrics, Patient-Generated Subjective Global Assessment (PG-SGA) score, QOL score and nutrient intake data were collected at baseline, week 4 and week 8. Blood was drawn for biochemical assessments. Nine patients from each group dropped out of the study Forty patients (18 control patients and 22 intervention patients) completed the study. Results: This study showed that ONS intervention improved PG-SGA scores in the intervention group (p<0.01). Scores of physical functioning score and role functioning were declined only in the control group and the difference between week 8 and baseline for role functioning was significant (p<0.001). Fatigue score was steadily decreased in the experiment group, and the differences between week 8 and baseline was significant between two groups (p<0.02). However, no statistically significant improvement in biochemical markers of nutritional status and pro-inflammatory cytokine concentrations were found. These results suggests that ONS intervention for 8 weeks improves PG-SGA scores and QOL scores in patients undergoing cancer therapy.

Validation of the Scored Patient-Generated Subjective Global Assessment (PG-SGA) in Thai Setting and Association with Nutritional Parameters in Cancer Patients

Background: The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is a multidimensional toolto assess malnutrition and risk factors. The objectives of this study are to determine the validity of the Thai version ofthe Scored PG-SGA (Thai PG-SGA) and examine the correlations with selected nutritional parameters. Methods: Thisobservational analytic study included 195 cancer patients aged greater than 18 years at a university-affiliated hospital inBangkok, Thailand. All patients were assessed for nutritional status by Thai PG-SGA in comparison to subjective globalassessment (SGA). Anthropometry, body composition, and hand grip strength were evaluated. Results: According toPG-SGA global assessment categories, 39% (75) of 195 cancer patients were well nourished, 27% (53) were moderatelymalnourished and 34% (67) of patients were severely malnourished. Thai PG-SGA had a sensitivity of 99.1% and aspecificity of 86.0% at predicting SGA classification. PG-SGA numerical scores were significantly different betweenwell-nourished and malnourished groups (4.2 ± 2.4 Vs 16.3 ± 4.9; p < 0.001). The PG-SGA scores, nutritional statusassessed by PG-SGA, and nutritional status assessed by SGA were correlated with weight, % weight loss in one month,body mass index, body fat, and hand grip strength (p < 0.001) respectively. Conclusions: Thai PG-SGA showed highsensitivity and good specificity in predicting malnutrition in Thai cancer patients. This tool demonstrated the correlationswith anthropometric parameters, body composition, and muscle strength.     

胃肠道肿瘤患者围化疗期营养状况的评价及对免疫功能的影响

目的:运用患者主观全面评价法(patient generated-subjective global assessment,PG-SGA)和营养风险筛查2002(nutrition risk screening 2002,NRS-2002)并结合实验室指标对围化疗期胃肠道肿瘤患者进行营养评价及免疫功能检测,观察营养不良及营养风险对相关临床指标的影响。方法:收集2012年2月至2014年2月期间于我院诊断为胃肠道恶性肿瘤术后待化疗患者80例,通过PG-SGA评分、NRS-2002评分、体格测量及实验室检测进行营养评价。检测T细胞亚群（CD4+、CD8+、CD4+/CD8+）。以PG-SGA评分作为营养评价指标,将80例化疗前患者分为A组（0-3分）、B组（4-8分）和C组（＞8分）,分别测定外周血T淋巴细胞亚群。其中资料完整的45例化疗患者于化疗6周期后重复上述内容,并观察化疗后并发症、平均住院时间。结果:PG-SGA评价结果为营养不良者占68.75%,NRS-2002评价结果营养不良者占42.50%。PG-SGA与NRS-2002分别与其他营养评价指标评价结果间均有显著相关性（P＜0.05）。随着营养不良评分的升高,CD4+和CD4+/CD8+均呈不同程度下降,差异有统计学意义（P＜0.05）。PG-SGA评分与CD4+之间的相关系数r=－0.399(P＜0.01);PG-SGA与CD4+/CD8+之间的相关系数r=－0.655(P＜0.01)。胃肠道肿瘤患者化疗后营养不良发生率高于化疗前。化疗后与化疗前,CD4+/CD8+明显下降,差异有显著性（P＜0.05）。化疗后营养不良组与营养良好组相比平均住院时间及并发症发生率显著增高（P＜0.05）。与无营养风险组相比,存在营养风险组的平均住院时间及并发症发生率显著增高（P＜0.05）。结论:联合运用PG-SGA、NRS-2002和实验室检测指标有助于提高肿瘤患者营养不良的诊断率。

目的 分析直肠癌同步放化疗患者营养状态与放化疗近期不良反应的相关性。方法 收集2018-2019年间浙江省肿瘤医院收治的115例行同步放化疗的直肠癌患者,同时采用欧洲营养风险筛查工具(NRS 2002)和患者主观整体评估量表(PG-SGA)评估患者放疗期间的营养风险状况,采用美国RTOG及不良反应常见术语标准评估急性放化疗不良反应。Spearman′s分析营养状态与放化疗急性不良反应相关性。结果 从放化疗开始前到放化疗第4周患者的营养风险呈逐步增加趋势,随后营养风险又逐步下降。NRS 2002评分和PG-SGA评分均与直肠癌放化疗患者血液学不良反应(r=0.26,P<0.05;r=0.31,P<0.01)、上消化道反应(r=0.51,P<0.01;r=0.63,P<0.01)、下消化道反应(r=0.23,P<0.05;r=0.45,P<0.01)、疲劳(r=0.47,P<0.01;r=0.64,P<0.01)均呈正相关,并且PG-SGA和不同不良反应之间的相关性系数大于NRS 2002。分层分析显示Ⅱ-ⅢB期、<65岁及术后辅助放化疗患者,营养状况和不良反应程度显著相关(均P<0.05)。结论 直肠癌患者同步放化疗期间存在较高的营养不良风险,营养不良风险越高患者放化疗急性不良反应通常越大,建议加强直肠癌放化疗期间的动态营养评估及支持。     

Correlation between nutritional status and toxicity of concurrent chemoradiotherapy in patients with rectal cancer

Objective To analyze the correlation between nutritional status and acute toxicity induced by concurrent chemoradiotherapy in patients with rectal cancer. Methods A total of 115 patients with rectal cancer who underwent concurrent chemoradiotherapy in Zhejiang Cancer Hospital from March 2018 to August 2019 were prospectively selected. Nutritional risk was assessed by NRS 2002 and PG-SGA nutritional screening tools before, during and after radiotherapy. The acute toxicity was assessed by RTOG and CTCAE 3.0 scoring criteria. The correlation between nutritional status and the acute toxicity of chemoradiotherapy was analyzed by Spearman′s correlation analysis. Results The nutritional risk of the cohort was gradually increased from the beginning of chemoradiotherapy to the fourth week of chemoradiotherapy, and then decreased gradually. Spearman′s correlation analysis showed that NRS 2002 and PG-SGA scores were positively correlated with acute hematological toxicity (r=0.26, P<0.05;r=0.31, P<0.01), upper gastrointestinal toxicity (r=0.51, P<0.01;r=0.63, P<0.01), proctitis (r=0.23, P<0.05;r=0.45, P<0.01) and fatigue (r=0.47, P<0.01;r=0.64, P<0.01) in patients with rectal cancer undergoing chemoradiotherapy. The correlation coefficients between PG-SGA and various toxicities were higher than those of NRS 2002. Stratified analysis showed that patients with stage Ⅱ-Ⅲ B, age<65 years and postoperative adjuvant chemoradiotherapy, nutritional status was significantly associated with the severity of toxicity (all P<0.05). Conclusions Patients with rectal cancer has a high risk of malnutrition during concurrent chemoradiotherapy. The higher the risk of malnutrition, the greater the acute toxicity of chemoradiotherapy. Therefore, dynamic nutrition assessment and nutritional support should be strengthened for rectal cancer patients during chemoradiotherapy.     

Nutritional assessment and risk factors associated to malnutrition in patients with esophageal cancer

Introduction: Esophageal cancer is the fourth most common cause of cancer death in China. Patients with esophageal cancer are more likely to suffer from malnutrition. The purpose of this study is to assess nutritional status of patients with esophageal cancer from multiple perspectives and analyze the risk factors. Methods: A total of 1482 esophageal cancer patients were enrolled in the study. We investigated the Scored Patient Generated Subjective Global Assessment (PG-SGA) scores, NRS-2002 scores, Karnofsky performance status scores, anthropometric, and laboratory indicators of patients. Unconditional logistic regression analysis was applied to identify the risk factors of nutritional status. Results: PG-SGA (≥4) and NRS-2002 (≥3) showed the incidence of malnutrition were 76% and 50%, respectively. In the patients with PG-SGA score ≥4, the proportion of patients who did not receive any nutritional support was 60%. The incidence of malnutrition in females was significantly higher than that in males. Besides, abnormality rates of Red blood cell (P < 0.001), MAC (P = 0.037), and MAMC (P < 0.001) in males was significantly higher than that in females, while abnormality rates of TSF (P < 0.001) was lower than that in females. After adjusted with the other potential risk factors listed, unconditional logistic regression analysis indicated smoking (odds ratio: 2.868, 95% confidence interval: 1.660-4.954), drinking (OR: 1.726, 95% CI: 1.099-2.712), family history (OR: 1.840, 95% CI: 1.132-2.992), radiotherapy or chemotherapy (OR: 1.594, 95% CI: 1.065-2.387), and pathological stage (OR: 2.263, 95% CI: 1.084-4.726) might be the risk factors of nutritional status, while nutritional support can reduce the risk of malnutrition. Conclusion: Effective nutritional risk assessment methods and nutritional intervention measures can be adopted according to the research data to improve quality of life of esophageal cancer patients.

Association of Nutritional Status with Quality of Life in Breast Cancer Survivors

Nutritional status and dietary intake play a significant role in the prognosis of breast cancer and may modifythe progression of disease. The aim of this study was to determine the influence of nutritional status on thequality of life of Iranian breast cancer survivors. Cross-sectional data were collected for 100 Iranian breastcancer survivors, aged 32 to 61 years, attending the oncology outpatient clinic at Golestan Hospital, Ahvaz, Iran.Nutritional status of subjects was assessed by anthropometric measurements, Patient-Generated SubjectiveGlobal Assessment (PG-SGA) and three non-consecutive 24-hour diet recalls. The European Organization ofResearch and Treatment of Cancer Quality of Life form (EORTC QLQ-C30) was used to assess quality of life.Ninety-four percent of the survivors were well-nourished, 6% were moderately malnourished or suspected ofbeing malnourished while none were severely malnourished. Prevalence of overweight and obesity was 86%.Overall, participants had an inadequate intake of vitamin D, E, iron and magnesium according to dietaryreference intake (DRI) recommendations. Survivors with better nutritional status had better functioning scalesand experienced fewer clinical symptoms. It appears important to provide educational and nutritional screeningprograms to improve cancer survivor quality of life.

Comparison of PG-SGA,SGA and body-composition measurement in detecting malnutrition among newly diagnosed lung cancer patients in stage IIIB/IV and benign conditions

Assessment tools and body-composition measurements are useful in diagnosing malnutrition. Which one is better for lung disease patients is unclear. The objectives of the present study are: to assess relationships between different methods of nutritional measurements in lung diseases patients; to determine which one is better in diagnosing malnutrition for lung disease patients; and to determine whether lung cancer patients can be differentiated from benign lung disease patients using different measurements. A total of 96 newly diagnosed primary lung cancer patients in stage IIIB/IV and 52 benign lung disease patients nutritional status were assessed according to the SGA, the scored PG-SGA, and serum albumin, prealbumin, transferrin, hemoglobin, total lymphocyte count, body mass index (BMI), and weight. A total of 40% of lung cancer patients were severely malnourished, with men or elder having a higher rate of malnutrition. Significantly lower values of weight, BMI, total lymphocyte count, transferrin, prealbumin and serum albumin were found for them. Age, sex, weight, weight half year ago and prealbumin are in the regression equation to predict them. For benign lung disease patients, 21.2% were severely malnourished with significantly lower values of weight and transferrin. Age and prealbumin are in the equation to predict severely malnourished benign lung disease patients. The highest receiver operation characteristic area under the curve was found for the PG-SGA score, BMI and weight. PG-SGA global rating, age and iron-transferring protein are in the equation for predicting disease status. The SGA and PG-SGA are appropriate for identifying malnutrition in lung disease patients. Lung cancer patients can be differentiated from benign conditions by PG-SGA.

Validation of nutritional risk index method against patient-generated 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.     

Evaluation of Nutritional Status of Cancer Patients during Treatment by Patient-Generated Subjective Global Assessment: a Hospital-Based Study

Cancer patients frequently experience malnutrition. Cancer and cancer therapy effects nutritional status through alterations in the metabolic system and reduction in food intake. In the present study, fifty seven cancer patients were selected as subjects from the oncology ward of Cachar Cancer Hospital and Research Centre, Silchar, India. Evaluation of nutritional status of cancer patients during treatment was carried out by scored Patient-Generated Subjective Global Assessment (PG-SGA). The findings of PG SGA showed that 15.8% (9) were well nourished, 31.6% (18) were moderately or suspected of being malnourished and 52.6% (30) were severely malnourished. The prevalence of malnutrition was highest in lip/oral (33.33%) cancer patients. The study showed that the prevalence of malnutrition (84.2%) was high in cancer patients during treatment.     

Utilization of a Scored Patient-Generated Subjective Global Assessment in Detecting a Malnourished Status in Gynecologic Cancer Patients

Purpose: To assess the prevalence of malnutrition in gynecologic cancer patients using the Scored Patient- Generated Subjective Global Assessment (PG-SGA) questionnaire. Materials and Methods: A total of 97 gynecologic cancer patients who never had any treatment but were planned for surgery were enrolled. The patients were asked to complete the scored PG-SGA form before the treatment was started. Attending physicians were also asked to complete other information in the PG-SGA form. Total scores were calculated and the patients were classified into 3 nutritional status levels. Results: Mean age was 54 years. Postoperative diagnoses were endometrial cancer in 42 cases (43.2%), ovarian cancer in 29 cases (29.9%), and cervical cancer in 26 cases (26.8%). Mean PG-SGA score was 5.24.7. Malnutrition (PG-SGA B and C) was found in 52 patients (53.6%, 95% CI 43.7% - 63.2%). Preoperative BMI, hemoglobin, serum albumin, and cancer stage were not significantly associated with nutritional status. Malnutrition was significantly more common among patients diagnosed with ovarian cancer, compared to other types of cancer (79.3% vs. 42.6%, p 0.004). Conclusions: Prevalence of malnutrition among gynecologic cancer patients was 53.5%, according to the scored PG-SGA. Malnutrition was significantly more common among patients with ovarian cancer.     

人体成分指标对预测鼻咽癌患者营养不良初步探讨

目的 探讨鼻咽癌患者同步放化疗期间营养状况与生活质量相关性,以期探索人体成分中评价营养不良最合适指标。方法 采用前瞻性方法以2014-2015年在复旦大学附属肿瘤医院放疗科48例鼻咽癌患者作为研究对象。采用欧洲肠外肠内营养学会营养不良诊断共识及患者主观整体评估方法进行营养评估,并采用生物电阻抗法观察同步放化疗期间患者的人体成分变化;采用Pearson法相关分析研究营养状况与生活质量的相关性;采用Logistics回归分析预测鼻咽癌患者营养状况的影响因素。结果 同步放化疗期间随时间变化人体成分指标如体重、体重指数、脂肪组织指数、去脂组织指数、体细胞量、骨骼肌量及相位角均有不同程度下降,患者主观整体评估评分逐渐升高(P=0.00)。根据2015年欧洲肠外肠内营养学会营养不良诊断共识检出放疗期间鼻咽癌营养不良发生率为2.1%~39.6%,根据患者主观整体评估评分检出率为12.5%~41.7%,两种方法在放疗第4、6周的一致性较好(Kappa=0.911、0.957)。放疗期间去脂组织指数和体重变化值与生活质量评分变化值存在相关性(r=0.805,P=0.00)(r=0.777,P=0.00)。因素分析显示年龄、脂肪组织指数、去脂组织指数对营养状况有显著影响(P=0.035、0.013、0.043)。结论 鼻咽癌患者放化疗期间营养状况下降明显,营养状况与患者生活质量密切相关,建立营养状况预测模型可更为全面准确地判断患者营养状况。

Quality of life as a predictor of cancer survival among Chinese liver and lung cancer patients

The utility of quality of life (QoL) scores in predicting cancer survival remains inconclusive because of methodological and/or statistical heterogeneity. We examined whether QoL scores predicted survival among Chinese liver (n=176) and lung cancer (n=358) patients. Cox proportional hazards models examined if QoL and psychosocial variables predicted survival after fully adjusting for sociodemographic and clinical factors. The results showed that global QoL scores did not predict survival in either patient group. Less advanced cancer stage (HR=2.574, p<0.05) was associated with longer survival in liver cancer. Longer survival in lung cancer was predicted by younger age (HR=1.016, p<0.05), less advanced cancer stage (HR=1.978, p<0.001), having had treatment before baseline (HR=0.671, p<0.05), better physical well-being (HR=0.941, p<0.001) and better appetite (HR=0.888, p<0.001).

足量营养支持改善肿瘤化疗患者癌因性疲乏和营养状况

目的:观察足量营养支持对肿瘤化疗患者癌因性疲乏（CRF）以及营养状况改善的影响。方法:选取我院自2018年03月-2019年03月间收治的恶性肿瘤化疗患者90例作为实验对象,按照数字随机原则分成两组,对照组45例行常规营养支持,观察组45例给予足量营养支持,采用营养风险筛查工具、Piper疲乏评估量表（RPFS-CV）以及癌症患者生命质量核心量表（EORTCQLQ-C30）对两组患者营养状况、癌因性疲乏、生活质量进行评估。结果:观察组营养风险评分明显低于对照组(P＜0.05);治疗前两组患者体质量指数（BMI）、前白蛋白（PA）、血清白蛋白（ALB）差异无统计学意义（P＞0.05）,治疗后观察组3项指标均显著升高,与对照组对比差异有统计学意义（P＜0.05）;治疗后两组情感疲乏、躯体疲乏和认知疲乏评分均显著下降,观察组降幅优于对照组（P＜0.05）;治疗后观察组EORTCQLQ-C30评分中功能领域、整体健康评分显著高于对照组,症状评分显著低于对照组（P＜0.05）。结论:肿瘤患者化疗期间采用足量营养支持能改善其营养状况,缓解癌因性疲乏等症状表现,全面提升患者的生活质量。
