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

Digital Health Intervention to Reduce Malnutrition Among Individuals With Gastrointestinal Cancer Receiving Cytoreductive Surgery Combined With Hyperthermic Intraperitoneal Chemotherapy: Feasibility, Acceptability, and Usability Trial

Background

Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) can improve survival outcomes for individuals with gastrointestinal (GI) cancer and peritoneal disease (PD). Individuals with GI cancer and PD receiving CRS-HIPEC are at increased risk for malnutrition. Despite the increased risk for malnutrition, there has been limited study of nutritional interventions for individuals receiving CRS-HIPEC.

Objective

We aimed to test the feasibility, acceptability, and usability of Support Through Remote Observation and Nutrition Guidance (STRONG), a multilevel digital health intervention to improve nutritional management among individuals with GI cancer and PD receiving CRS-HIPEC. We also assessed patient-reported outcomes, including malnutrition risk, health-related quality of life, and weight-related measures.

Methods

STRONG is a 12-week digital intervention in which participants received biweekly nutritional counseling with a dietitian, logged food intake using a Fitbit tracker, and reported nutrition-related outcomes. Dietitians received access to a web-based dashboard and remotely monitored patients' reported food intake and nutrition-impact symptoms. Implementation outcomes were assessed against prespecified benchmarks consistent with benchmarks used in prior studies. Changes in patient-reported outcomes at baseline and follow-up were assessed using linear and ordered logistic regressions.

Results

Participants (N=10) had a median age of 57.5 (IQR 54-69) years. Feasibility benchmarks were achieved for recruitment (10/17, 59% vs benchmark: 50%), study assessment completion (9/10, 90% vs benchmark: 60%), dietitian appointment attendance (7/10, 70% vs benchmark: 60%), daily food intake logging adherence (6/10, 60% vs benchmark: 60%), and participant retention (10/10, 100% vs benchmark: 60%). Most participants rated the intervention as acceptable (8/10, 80% vs benchmark: 70%) and reported a high level of usability for dietitian services (10/10, 100%). The benchmark usability for the Fitbit tracker to log food intake was not met. Compared to baseline, participants saw on average a 6.0 point reduction in malnutrition risk score (P=.01), a 20.5 point improvement in general health-related quality of life score (P=.002), and a 5.6 percentage point increase in 1-month weight change (P=.04) at the end of the study.

Conclusions

The STRONG intervention demonstrated to be feasible, acceptable, and usable among individuals with GI cancer and PD receiving CRS-HIPEC. A fully powered randomized controlled trial is needed to test the effectiveness of STRONG for reducing malnutrition and improving patient outcomes.

Evaluating the accuracy of a nutritional screening tool for patients with digestive system tumors: A hierarchical Bayesian latent class meta-analysis

BACKGROUND

Cancer, particularly tumors of the digestive system, presents a major global health challenge. The incidence and mortality rates of these cancers are increasing, and many patients face significant nutritional risks, which are often overlooked in clinical practice. This oversight can lead to serious health consequences, underscoring the need for effective nutritional assessment tools to improve clinical outcomes. Although several nutritional risk screening tools exist, their specific utility for patients with gastrointestinal tumors remains unclear. This study aimed to address this gap by systematically evaluating the performance of various nutritional screening tools in this patient population.

METHODS

A systematic search of six databases was conducted to identify studies that met predefined inclusion and exclusion criteria. Diagnostic test metrics such as sensitivity, specificity, and likelihood ratios (positive and negative) were estimated using a hierarchical summary receiver operating characteristic model. This approach was used to compare the accuracy of different nutritional screening scales.

RESULTS

A total of 33 eligible studies were included in this meta-analysis, assessing six nutritional screening tools: the Malnutrition Universal Screening Tool, Malnutrition Screening Tool, Nutritional Risk Screening 2002, Mini Nutritional Assessment-Short Form, Nutritional Risk Index, and Patient-Generated Subjective Global Assessment. Among these, the Patient-Generated Subjective Global Assessment demonstrated the highest performance, with a sensitivity of 0.911 (95% confidence interval: 0.866-0.942) and a specificity of 0.805 (95% confidence interval: 0.674-0.891), outperforming the other screening tools.

CONCLUSIONS

This study confirms the effectiveness of the Patient-Generated Subjective Global Assessment in identifying malnutrition risk among patients with digestive system tumors. However, as this research focused on a Chinese population, future studies should encompass a broader geographic scope and work toward standardized assessment criteria to enhance the global validation and refinement of nutritional screening tools.

Updated systematic review and meta‑analysis for risk predictors of 30‑day unplanned readmission following gastric cancer surgery

Readmission to hospital is a common occurrence due to adverse post-operative events. The primary objective of the present study was to examine the possible risk predictors for 30-day unplanned readmissions after the surgical treatment of gastric cancer. The secondary aim was to determine the clinical characteristics that are associated with readmission. Studies that reported the risk factors and clinical characteristics of patients with gastric cancer who had an unplanned 30-day post-operative readmission were identified systematically from PubMed, Cochrane Central Register of Controlled Trials, Web of Science and Embase databases, with a final search date of March 30, 2024. A systematic review and meta-analysis were then performed to estimate the risk predictors and relevant clinical characteristics for readmission. A total of 16,154 patients from 12 studies were included in the present study, with 1,736 patients who were readmitted and 14,418 patients who were not readmitted. A higher proportion of patients with an age ≥70 years, cardiovascular comorbidity, Nutritional Risk Screening (NRS) 2002 score ≥3, respiratory diseases, male sex, American Society of Anesthesiologists score ≥3, combined multi-organ resection, greater depth of invasion (T3-4/T1-2), discharge to home with provision of care services, neoadjuvant therapy, post-operative complications or a blood transfusion were found in the readmission group compared with that in the non-readmission group. A meta-analysis was also performed to calculate risk predictors using the results of multivariate regression analyses from the original literature. This identified cardiovascular comorbidity, NRS 2002 score ≥3, pancreatectomy and post-operative complications as risk predictors for 30-day unplanned readmission following surgery for gastric cancer. Therefore, it is recommended that extra attention and support should be given to patients with these high-risk predictors during the perioperative period.

Malnutrition screening tool and nutritional screening tool for classification of nutritional risk in patients with cancer upon hospital admission: Comparison of diagnostic performance using Global Leadership Initiative on malnutrition criteria as reference

BACKGROUND & AIMS

Tools for screening of nutrition risk in patients with cancer are usually validated against other screening instruments. Here with the performance of Malnutrition Screening Tool (MST) and Nutritional Screening Tool (NUTRISCORE) to identify the risk of malnutrition was assessed. A full nutritional evaluation and diagnosis following criteria from the Global Leadership Initiative of Malnutrition (GLIM) was the reference standard for the classification of malnutrition.

METHODS

Diagnostic test prospective analysis of adult patients with a confirmed diagnosis of cancer. MST, NUTRISCORE and nutritional evaluation and diagnosis by GLIM criteria were independently performed within 24 h of admission to a 4th tier hospital in Bogotá, Colombia.

RESULTS

From 439 patients the sensitivity and specificity of MST was 75% and 94% and of NUTRISCORE 45% and 97% respectively. The area under receiver operating characteristic (ROC) curves were 0.90 for MST and 0.85 for NUTRISCORE (p = 0.003).

CONCLUSION

The MST showed a significantly better diagnostic performance over NUTRISCORE for detection of malnutrition risk at admission to hospital of patients with cancer.

Enteral Nutrition in Operated-On Gastric Cancer Patients: An Update

It is well established that the preoperative nutritional status of gastric cancer (GC) patients significantly affects the prognosis of the operated patients, their overall survival, as well as the disease-specific survival. Existing data support that preoperative assessment of nutritional status and early correction of nutritional deficiencies exert a favorable effect on early postoperative outcomes. A variety of relevant indices are used to assess the nutritional status of GC patients who are candidates for surgery. The guidelines of almost all international organizations recommend the use of oral enteral nutrition (EN). Oncologically acceptable types of gastrectomy and methods of patient rehabilitation should take into account the expected postoperative nutritional status. The majority of data support that perioperative EN reduces complications and hospital stay, but not mortality. Oral EN in the postoperative period, albeit in small amounts, helps to reduce the weight loss that is a consequence of gastrectomy. Iron deficiency with or without anemia and low serum levels of vitamin B12 are common metabolic sequelae after gastrectomy and should be restored. EN also significantly helps patients undergoing neoadjuvant or adjuvant antineoplastic therapy. The occurrence of the so-called "postgastrectomy syndromes" requires dietary modifications and drug support. This review attempts to highlight the benefits of EN in GC patients undergoing gastrectomy and to emphasize the type of necessary nutritional management, based on current literature data.

Assessing Nutritional Status in Gastric Cancer Patients after Total versus Subtotal Gastrectomy: Cross-Sectional Study

Gastric cancer (GC) remains a significant global health concern, ranking as the third leading cause of cancer-related deaths. Malnutrition is common in GC patients and can negatively impact prognosis and quality of life. Understanding nutritional issues and their management is crucial for improving patient outcomes. This cross-sectional study included 51 GC patients who underwent curative surgery, either total or subtotal gastrectomy. Various nutritional assessments were conducted, including anthropometric measurements, laboratory tests, and scoring systems such as Eastern Cooperative Oncology Group/World Health Organization Performance Status (ECOG/WHO PS), Observer-Reported Dysphagia (ORD), Nutritional Risk Screening-2002 (NRS-2002), Patient-Generated Subjective Global Assessment (PG-SGA), and Simplified Nutritional Appetite Questionnaire (SNAQ). Serum carcinoembryonic antigen (CEA) levels were significantly higher in the subtotal gastrectomy group. Nutritional assessments indicated a higher risk of malnutrition in patients who underwent total gastrectomy, as evidenced by higher scores on ORD, NRS-2002, and PG-SGA. While total gastrectomy was associated with a higher risk of malnutrition, no single nutritional parameter emerged as a strong predictor of surgical approach. PG-SGA predominantly identified malnutrition, with its occurrence linked to demographic factors such as female gender and age exceeding 65 years.

Perioperative nutritional assessment and management of patients undergoing gastrointestinal surgery

Malnutrition is a major issue in gastrointestinal perioperative situations, as only 40% of malnourished patients are finally treated. This literature review investigates the inconsistencies regarding the diagnostic approach to both preoperative and postoperative patients and the various underlying causes, as well as the efficiency of the various therapeutic regimens. A literature search was conducted until August 2023 in MEDLINE and Scopus. Clinical studies involving perioperative nutritional assessment in adult gastrointestinal surgery patients during the last 10 years were included in the present review. Finally, 19 articles were included in the study. Preoperative nutritional therapy is increasingly recognized as a key component of surgical care. Malnourished patients who are hospitalized and operated on, have significantly worse clinical results. Gastrointestinal postoperative malnutrition coexists with metabolic stress, as patients usually suffer from minor chronic inflammations; therefore, postoperative malnutrition is the result of a combination of the effects of inflammation and a lack of food intake. Postoperative malnutrition leads to prolonged hospitalizations and hospital complications and therefore the need to treat it is essential. There are many recognized tools for detecting malnutrition. However, all tools showed inconsistent results regarding their validity. Per os feeding after surgery, and dietary supplements when necessary, have been recommended. Therefore, it is very important to reduce malnutrition and define clear strategies towards that direction.

Development and validation of self-screening tool for nutrition risk in patients with gastric cancer after gastrectomy: A study protocol

AIM

This study aims to develop and validate a clinical nutrition risk screening tool to predict nutrition risk in home for the patients with gastric cancer after surgery at home so that high-risk patients can be targeted for preventive nutrition care.

DESIGN

The development of self-screening tool for nutrition risk in patients with gastric cancer after gastrectomy (SNRSGC) through literature review, expert panel ratings and cognitive interview; the validation of SNRSGC is evaluated through prospective research on participants.

METHODS

This research is divided into four parts: Step 1, Identification of a potential referred nutritional risk screening; Step 2, Item generation and scoring are selected through literature review methods to screen sensitive indicators which can reflect the nutritional characteristics of patients after gastric cancer surgery, establish the frame and update according to the latest guidelines; Step 3, Item reduction is determined by the rating of SNRSGC items by an expert panel and cognitive interview; Step 4, During the validation stage, we conducted research design based on the Consensus-based Standards for the selection of health Measurement Instruments checklist to evaluate the validity, reliability, interpretability and acceptability of SNRSGC.

RESULTS

SNRSGC is the first screening tool specifically to predict nutrition risk for stay-at-home postoperative patients with gastric cancer, which can help patients at home detect nutritional risks at home in time and guide patients to seek medical treatment as soon as possible to improve their nutritional status.

Diagnostic test accuracy of preoperative nutritional screening tools in adults for malnutrition: a systematic review and network meta-analysis

BACKGROUND

Good nutritional screening tests can triage malnourished patients for further assessment and management by dietitians before surgery to reduce the risk of postoperative complications. The authors assessed the diagnostic test accuracy of common nutritional screening tools for preoperative malnutrition in adults undergoing surgery and determined which test had the highest accuracy.

METHODS

MEDLINE, EMBASE, CINAHL, and Web of Science were searched for relevant titles with no language restriction from inception till 1 January 2023. Studies reporting on the diagnostic test accuracy of preoperative malnutrition in adults using one or more of the following index nutritional screening tools were included: Malnutrition Screening Tool (MST), Malnutrition Universal Screening Tool (MUST), Mini Nutritional Assessment (MNA), short-form Mini Nutritional Assessment (MNA-SF), Nutritional Risk Index (NRI), Nutrition Risk Screening Tool 2002 (NRS-2002), and Preoperative Nutrition Screening (PONS). The reference standard was the Subjective Global Assessment (SGA) before surgery. Random-effects bivariate binomial model meta-analyses, meta-regressions, and a network meta-analysis were used to estimate the pooled and relative sensitivities and specificities.

RESULTS

Of the 16 included studies (5695 participants with an 11 957 index and 11 957 SGA tests), all were conducted after hospital admission before surgery. Eleven studies ( n =3896) were at high risk of bias using the Quality Assessment of Diagnostic Accuracy Studies tool due to a lack of blinded assessments. MUST had the highest overall test accuracy performance (sensitivity 86%, 95% CI: 75-93%; specificity 89%, 95% CI: 83-93%). Network meta-analysis showed NRI had similar relative sensitivity (0.93, 95% CI: 0.77-1.13) but lower relative specificity (0.75, 95% CI: 0.61-0.92) than MUST.

CONCLUSIONS

Of all easy-to-use tests applicable at the bedside, MUST had the highest test accuracy performance for screening preoperative malnutrition. However, its predictive accuracy is likely insufficient to justify the application of nutritional optimization interventions without additional assessments.

The prognostic nutritional index (PNI) is independently associated with 90-day and 12-month mortality after metastatic spinal tumor surgery

INTRODUCTION

Estimated postoperative survival is an important consideration during the decision-making process for patients with spinal metastases. Nutritional status has been associated with poor outcomes and limited survival in the general cancer population. The objective of this study was to evaluate the predictive utility of the prognostic nutritional index (PNI) for postoperative mortality after spinal metastasis surgery.

METHODS

A total of 139 patients who underwent oncologic surgery for spinal metastases between April 2012 and August 2022 and had a minimum 90-day follow-up were included. PNI was calculated using preoperative serum albumin and total lymphocyte count, with PNI < 40 defined as low. The mean PNI of our cohort was 43 (standard deviation: 7.7). The primary endpoint was 90-day mortality, and the secondary endpoint was 12-month mortality. Multivariate logistic regression analyses were performed.

RESULTS

The 90-day mortality was 27% (37/139), and the 12-month mortality was 56% (51/91). After controlling for age, ECOG performance status, total psoas muscle cross-sectional area (TPA), and primary cancer site, the PNI was associated with 90-day mortality [odds ratio 0.86 (95% confidence interval 0.79-0.94); p = 0.001]. After controlling for ECOG performance status and primary cancer site, the PNI was associated with 12-month mortality [OR 0.89 (95% CI 0.82-0.97); p = 0.008]. Patients with a low PNI had a 50% mortality rate at 90 days and an 84% mortality rate at 12 months.

CONCLUSION

The PNI was independently associated with 90-day and 12-month mortality after metastatic spinal tumor surgery, independent of performance status, TPA, and primary cancer site.

Early vs delayed enteral nutrition or parenteral nutrition in hospitalized patients: An umbrella review of systematic reviews and meta-analyses of randomized trials

We conducted an umbrella review to summarize the existing evidence on the effect of early enteral nutrition (EEN) compared with other approaches, including delayed enteral nutrition (DEN), parenteral nutrition (PN), and oral feeding (OF) on clinical outcomes in hospitalized patients. We performed a systematic search up to December 2021, in MEDLINE (via PubMed), Scopus, and Institute for Scientific Information Web of Science. We included systematic reviews with meta-analyses (SRMAs) of randomized trials investigating EEN compared with DEN, PN, or OF for any clinical outcomes in hospitalized patients. We used "A Measurement Tool to Assess Systematic Reviews" (AMSTAR2) and the Cochrane risk-of-bias tool for assessing the methodological quality of the systematic reviews and their included trial, respectively. The certainty of the evidence was rated using the "Grading of Recommendations Assessment, Development, and Evaluation" (GRADE) approach. We included 45 eligible SRMAs contributing with a total of 103 randomized controlled trials. The overall meta-analyses showed that patients who received EEN had statistically significant beneficial effects on most outcomes compared with any control (ie, DEN, PN, or OF), including mortality, sepsis, overall complications, infection complications, multiorgan failure, anastomotic leakage, length of hospital stay, time to flatus, and serum albumin levels. No statistically significant beneficial effects were found for risk of pneumonia, noninfectious complications, vomiting, wound infection, as well as number of days of ventilation, intensive care unit days, serum protein, and pre-serum albumin levels. Our results indicate that EEN may be preferred over DEN, PN, and OF because of the beneficial effects on many clinical outcomes.

Effects of oral immunonutritional supplement on 3-year disease-free survival in gastric cancer patients with pathological stage III after total gastrectomy (CRUCIAL): study protocol of a multicentre, randomised clinical trial

INTRODUCTION

The nutritional status of patients with gastric cancer (GC) after total gastrectomy continues to deteriorate and lasts a long time after discharge, which is an independent risk factor for mortality. Recent guidelines have recommended appropriate nutritional support after discharge for cancer surgery patients with malnutrition or nutritional risk. The evidence on the efficacy of oral immunonutritional supplement (INS) and its effect on long-term disease-free survival (DFS) in patients with GC is limited. This study was designed to test the hypothesis that oral INS compared to diet alone may improve 3-year DFS of GC patients with pathological stage III after total gastrectomy (Nutrition Risk Screening 2002 score ≥3 at discharge).

METHODS AND ANALYSIS

This is a pragmatic, open-label, multicentre, randomised controlled study. 696 eligible GC patients with pathological stage III after total gastrectomy will be randomised in a 1:1 ratio to oral INS group or normal diet group for 6 months. The primary endpoint is 3-year DFS after discharge. The following secondary endpoints will be evaluated: 3-year overall survival; unplanned readmission rate at 3 and 6 months after discharge; quality of life, body mass index and haematological index at 3, 6 and 12 months after discharge; incidence of sarcopenia at 6 and 12 months after discharge; and the tolerance to chemotherapy. The adverse events of oral INS will also be evaluated during the intervention.

ETHICS AND DISSEMINATION

This study was approved by the ethics committee of Jinling Hospital, Nanjing University (number 2021NZKY-069-01). The present study may validate the effectiveness of oral immunonutritional therapy in improving 3-year DFS for GC patients with pathological stage III after total gastrectomy for the first time. The results of this trial will be disseminated in peer-reviewed journals and at scientific conferences.

TRIAL REGISTRATION NUMBER

Assessing the Effects of a Perioperative Nutritional Support and Counseling in Gastrointestinal Cancer Patients: A Retrospective Comparative Study with Historical Controls

The aim of this study was to investigate the effects of perioperative nutritional therapy care in gastrointestinal (esophageal, gastric, gastroesophageal) cancer patients on nutritional status and disease progression (complications, hospitalization, mortality). We considered 62 gastrointestinal cancer patients treated at the Center for Integrated Oncology (CIO), University Hospital Bonn, Germany (August 2017-July 2019). Of these, 42 patients (as intervention group: IG) received pre- and postoperative nutritional support with counseling, while 20 patients (as historical control group CG) received only postoperative nutritional therapy. Several clinical parameters, such as Body Mass Index (BMI), nutritional risk screening (NRS), phase angle, postoperative complications, length of hospital stay, and mortality, were determined. There were significantly fewer patients with gastric cancer/CDH1 gene mutation and more with esophageal cancer in IG (p = 0.001). Significantly more patients received neoadjuvant therapy in IG (p = 0.036). No significant differences were found between the groups regarding BMI, NRS, complications, length of hospital stay, and mortality. However, the comparison of post- and preoperative parameters in IG showed a tendency to lose 1.74 kg of weight (p = 0.046), a decrease in phase angle by 0.59° (p = 0.004), and an increase in NRS of 1.34 points (p < 0.001). Contrary to prior reports, we found no significant effect of perioperative nutritional therapy care in gastrointestinal cancer patients; however, the small cohort size and infrequent standardization in nutritional status may possibly account for the variance. Considering that oncological pathways and metabolic nutritional pathways are interrelated, dividing patients into subgroups to provide a personalized nutritional approach may help in improving their treatment.

Nutrition Intervention in a Gastric Cancer Patient With Gastrectomy for 12 Months: A Case Report

Gastrectomy is the most effective method of treating gastric cancer, but it is commonly associated with weight loss, nutritional deficiencies, and the increased risk of malnutrition due to post-surgery complications, including gastric stasis, dumping syndrome, malabsorption, and maldigestion. Malnutrition is a risk factor for postoperative complications and poor prognosis. To prevent it and guarantee a quick recovery after surgery, continuous and individualized nutrition intervention should be performed both before surgery and postoperatively. The Department of Dietetics at Samsung Medical Center (SMC) performed nutritional status assessment before gastrectomy, initial nutritional assessment within 24 hours of admission, description of therapeutic diet after surgery, nutrition counselling before discharge, and nutritional status assessment and individual nutrition counselling after 1, 3, 6, and 12 months from surgery. This is a case report of a patient who underwent gastrectomy as well as intensive nutrition intervention in SMC.

Nutritional status assessed by Patient-Generated Subjective Global Assessment is associated with toxicity to chemoradiotherapy in women with cervical cancer: a prospective study

BACKGROUND

Patient-generated subjective global assessment (PG-SGA), a validated tool for nutritional assessment, has been associated with worse clinical outcomes in patients with cancer. However, studies assessing its relationship in chemoradiotherapy outcomes are scarce. The study aimed to determine the prevalence of malnutrition according to PG-SGA and its association with the incidence of toxicity to chemoradiotherapy treatment in women with cervical cancer.

METHODS

In a single-centre prospective observational study, we enrolled 391 women with locally advanced cervical cancer. Patients were assessed on the day of their first chemotherapy infusion, when nutritional status was evaluated by the PG-SGA form and anthropometric measurements. Sociodemographic and clinical data were also collected. Toxicity to chemoradiotherapy was assessed weekly and toxicity-induced modification of treatment (TIMT) was defined as any serious adverse event that resulted in treatment delay, interruption, or dose reduction. Multivariate mixed-effects Poisson and Logistic regression models were performed to identify the factors contributing to the outcome number of adverse events ≥ grade 3 and TIMT, respectively.

RESULTS

Malnutrition was found in 47.6% of the population. Roughly 1/3 had TIMT and 54.2% experienced at least one symptom ≥grade 3. In the adjusted models, PG-SGA B and C, as well as the score ≥9 were independent predictors of the number of toxicity events ≥grade 3 and higher incidence of TIMT.

CONCLUSIONS

PG-SGA may represent an important assessment tool to predict toxicity outcomes in women with cervical cancer, besides being considered a simple, fast, and low-cost tool, which allows early nutritional care.

Harmonization and standardization of malnutrition screening for all adults - A systematic review initiated by the Norwegian Directorate of Health

BACKGROUND & AIMS

The Norwegian Directorate of Health has identified a need to harmonize and standardize the malnutrition screening practice in Norwegian hospitals and primary health care settings, in order to provide a seamless communication of malnutrition screening along the patient pathway. Our aim was to perform a systematic review of the validity and reliability of screening tools used to identify risk of malnutrition across health care settings, diagnoses or conditions and adult age groups, as a first step towards a national recommendation of one screening tool.

METHODS

A systematic literature search for articles evaluating validity, agreement, and reliability of malnutrition screening tools, published up to August 2020, was conducted in: MEDLINE, Embase, APA PsycInfo, Cinahl, Cochrane Databases, Web of Science, Epistemonikos, SveMed+, and Norart. The systematic review was registered in PROSPERO (CRD42022300558). For critical appraisal of each included article, the Quality Criteria Checklist by The Academy of Nutrition and Dietetics was used.

RESULTS

The review identified 105 articles that fulfilled the inclusion and exclusion criteria. The most frequently validated tools were Mini Nutritional Assessment short form (MNA), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST), and Nutritional Risk Screening 2002 (NRS-2002). MNA, MST and NRS-2002 displayed overall moderate validity, and MUST low validity. All four tools displayed low agreement. MST and MUST were validated across health care settings and age groups. In general, data on reliability was limited.

CONCLUSIONS

The screening tools MST and NRS-2002 displayed moderate validity for the identification of malnutrition in adults, of which MST is validated across health care settings. In addition, MNA has moderate validity for the identification of malnutrition in adults 65 years or older.

Nutrition Care in Cancer Surgery Patients: A Narrative Review of Nutritional Screening and Assessment Methods and Nutritional Considerations

Malignancy is a catabolic state, which is precipitated with surgical intervention. Malnutrition is one of the main risk factors for poor outcomes of cancer surgery. We need to screen oncological patients for malnutrition using standardized screening tools, by which patients found to be at nutritional risk are then referred to a registered dietitian for further management. A detailed assessment is required in such patients, which helps in categorizing the patients based on the severity and rendering proper care. Preoperative nutrition care is often overlooked because of the urgency of operating on a cancer patient. Still, studies have shown preoperative nutritional building gives better surgical outcomes and good postoperative quality of life. Preoperative nutrition care includes both early and late preoperative care. For efficient preoperative nutrition care publishing, standard operating procedures at every healthcare center are recommended. Postoperative nutrition care is given to build the patient tackle the surgical trauma, and their diet mainly includes protein to minimize catabolism. Regardless of the route of nutrition delivery, providing appropriate nutrition care in the postoperative period improves cancer patients' condition drastically. Early postoperative nutrition is studied in different cancer surgeries and is considered ideal in cancer surgical patients. There is a need for consensus on the composition of postoperative nutrition. The diet of a cancer patient should include micronutrients like vitamins D and B and minerals along with the usual nutrition care. The use of special diets like branched-chain amino acids and immune nutrition is to be considered on a case-by-case basis and introducing them into the routine care of a patient needs to be studied extensively.

Malnutrition management in oncology: An expert view on controversial issues and future perspectives

Cancer and anticancer treatments can lead to several negative side effects, including malnutrition. Despite the recognized need for adequate nutritional support in cancer patients, in daily clinical practice, nutrition is still not considered one of the first aspects to be considered. Malnutrition negatively affects the clinical outcomes, treatment response, and overall survival of cancer patients. In this study, three of the most controversial issues related to malnutrition, which emerged during an Italian Consensus Conference, were addressed specifically for patients with head and neck as well as gastrointestinal cancer. The timing of nutritional evaluation and intervention, extension of the Enhanced Recovery after Surgery (ERAS^®) protocols, and cost-effectiveness of nutritional interventions have been considered. This study aimed to illustrate the state-of-the art of each issue and hypothesize future perspectives and actions to be taken, trying to suggest a new nutritional management model for cancer patients in Italy that overcomes the critical issues encountered. Of note, the timely diagnosis of nutritional issue appears to be essential to ensure the correct management of malnourished cancer patients as well as those who are at high risk of malnutrition. Standardized protocols, screening tests, and the inclusion of nutritional parameters in patient medical records would help to achieve good clinical outcomes. Finally, appropriate nutritional support is also associated with cost savings, and it seems necessary to promote its clinical and economic value to obtain improvements in both outcomes and management costs.

Evaluation of Nutritional Status and Anxiety Levels in Patients Applying to the Radiation Oncology Outpatient Clinic during the COVID-19 Pandemic: Turkish Society for Radiation Oncology Group Study (TROD 12:02)

Cancer patients often face malnutrition, which negatively affects their response to cancer treatment. This study aims to analyze the effects of the COVID-19 pandemic on nutritional status and anxiety in cancer patients with different types and stages of cancer. This is a cross-sectional cohort study that includes 1,252 patients with varying cancer types from 17 radiation oncology centers. The nutritional risk scores (NRS-2002) and coronavirus anxiety scale (CAS) scores of all patients were measured. NRS-2002 ≥ 3 and CAS ≥ 5 were accepted as values at risk. Of all patients, 15.3% had NRS-2002 ≥ 3. Breast cancer was the most prevalent cancer type (24.5%) with the lowest risk of nutrition (4.9%, p < 0.001). Nutritional risk was significantly higher in patients with gastrointestinal cancer, head and neck cancer, and lung cancer (p < 0.005) and in patients with stage IV disease (p < 0.001). High anxiety levels (CAS ≥ 5) were significantly related to voluntary avoidance and clinical postponement of hospital visits due to the pandemic (p < 0.001), while clinical postponement was particularly frequent among patients with NRS-2002 < 3 (p = 0.0021). Fear and anxiety in cancer patients with COVID-19 cause hesitations in visiting hospitals, leading to disrupted primary and nutritional treatments. Thus, nutritional monitoring and treatment monitoring of cancer patients are crucial during and after radiotherapy.

Applicability of five nutritional screening tools in Chinese patients undergoing colorectal cancer surgery: a cross-sectional study

OBJECTIVES

To identify the most appropriate nutritional risk screening tool for patients undergoing colorectal cancer surgery, five nutritional screening tools, including the Nutritional Risk Screening 2002 (NRS 2002), Short Form of Mini Nutritional Assessment (MNA-SF), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST) and Nutritional Risk Index (NRI), were employed to evaluate the nutritional risk at admission and short-term clinical outcome prediction.

DESIGN

A cross-sectional study.

SETTING

A comprehensive affiliated hospital of a university in Shenyang, Liaoning Province, China.

PARTICIPANTS

301 patients diagnosed with colorectal cancer were continuously recruited to complete the study from October 2020 to May 2021.

PRIMARY AND SECONDARY OUTCOME MEASURES

Within 48 hours of hospital admission, five nutritional screening tools were used to measure the nutritional risk and to determine their relationship with postoperative short-term clinical outcomes.

RESULTS

The nutritional risk assesed by the five tools ranged from 25.2% to 46.2%. Taking the Subject Global Assessment as the diagnostic standard, MNA-SF had the best consistency (κ=0.570, p<0.001) and MST had the highest sensitivity (82.61%). Multivariate Logistic regression analysis after adjusting confounding factors showed that the NRS 2002 score ≥3 (OR 2.400, 95% CI 1.043 to 5.522) was an independent risk factor for postoperative complications and was the strongest predictor of postoperative complications (area under the curve 0.621, 95% CI 0.549 to 0.692). The scores of NRS 2002 (r=0.131, p<0.001), MNA-SF (r=0.115, p<0.05) and NRI (r=0.187, p<0.05) were poorly correlated with the length of stay. There was no correlation between the five nutritional screening tools and hospitalisation costs (p>0.05).

CONCLUSIONS

Compared with the other four nutritional screening tools, we found that NRS 2002 is the most appropriate nutritional screening tool for Chinese patients with colorectal cancer.

Association of Sarcopenia and Low Nutritional Status with Unplanned Hospital Readmission after Radical Gastrectomy in Patients with Gastric Cancer: A Case-Control Study

Objective. Sarcopenia is one of the influencing factors of poor prognosis in patients with gastric cancer but the association with readmission are unknown. We aimed to explore factors associated with readmission after gastrectomy and to determine whether preoperative sarcopenia is a common outcome in readmitted patients. Methods. In this case-control study, patients who underwent gastric resection in the First Affiliated Hospital of Wenzhou Medical University between April 2016 and September 2017 were included. The reasons of readmission patients were described. The readmission patients and non-readmission patients were matched by propensity score matching (PSM). The univariate analysis was applied for the baseline characteristics, operative details, postoperative prognosis and discharge disposition, and multiple logistic regression analysis for the independent risk factors of readmission. Results. The unplanned readmission rate within 30 days of radical gastrectomy for gastric cancer was 6.5% (43/657). The average time interval from discharge to readmission was 13 days. Delayed gastric evacuation was the main cause of readmission (18.6%, 8/43). Body mass index (BMI), nutritional risk screening (NRS) 2002 score, history of abdominal surgery, sarcopenia, and preoperative albumin were included in the multivariate logistic regression analysis. NRS 2002 (OR = 3.43, 95% CI: 1.10–10.72, $P=0.034$ ) and sarcopenia (OR = 4.25, 95% CI: 1.13–16.02, $P=0.033$ ) were found to be independently associated with unplanned readmission within 30 days of radical gastrectomy for cancer. Other factors such as age, sex, BMI, American Society of Anesthesiologists grade, surgical method, operation and reconstruction type, TNM stage, surgical duration, previous abdominal surgery, and preoperative albumin and hemoglobin level were not associated with unplanned readmission after radical gastrectomy for cancer. Conclusions. Sarcopenia and low nutritional status are independently associated with unplanned readmission within 30 days of radical gastrectomy for cancer.

Perioperative nutrition management for gastric cancer

Gastric cancer is one of the most frequently diagnosed and the leading cause of cancer death worldwide. Malnutrition is a substantial problem in patients with gastric cancer, associated with poor treatment tolerance and increased morbidity. It has also been recognized as an independent prognostic factor in individuals with cancer. Early detection of malnutrition and effective perioperative nutrition intervention play an important role in the treatment of gastric cancer. Nutrition screening and assessment are the first steps in nutrition management and provide a basis for further nutrition support. Several tools, including the Nutrition Risk Screening-2002 and Patient-Generated Subjective Global Assessment, have been developed for nutrition screening and assessment. Effective nutrition support can significantly improve nutritional and immune status, reduce the incidence of postoperative complications, and accelerate recovery. The aim of this review was to focus on preoperative nutrition risk screening and assessment, and perioperative nutrition support, which may serve as a framework of perioperative nutrition management for gastric cancer.

Prognostic value of hemoglobin combined with Geriatric Nutritional Risk Index scores in patients undergoing postoperative radiotherapy for esophageal squamous cell carcinoma

Aims: To investigate the prognostic value of hemoglobin combined with geriatric nutritional risk index (GNRI) scores in patients undergoing postoperative radiotherapy for esophageal squamous cell carcinoma (ESCC). Patients & methods: Patients who underwent esophagectomy and postoperative radiotherapy were included in this retrospective study. Their preoperative hemoglobin and GNRI were collected to establish hemoglobin-GNRI (H-GNRI) scores, and their association with OS was evaluated. Results: Patients with high H-GNRI scores had better prognosis than those with low scores (p < 0.001). Differentiation (p = 0.001), T classification (p = 0.010), N classification (p = 0.001) and H-GNRI score (p = 0.018) were independent prognostic factors for all patients. Conclusion: H-GNRI score is an independent prognostic factor for the survival of patients with ESCC managed by surgery and postoperative radiotherapy.

A Prospective Review of Preoperative Nutritional Status and Its Influence on the Outcome of Abdominal Surgery

Aim

To assess the incidence of malnutrition in a surgical gastroenterology unit and analyze its impact on postoperative complication rates.

Method

Data were prospectively accrued from patients admitted for emergency or elective surgery to the gastrointestinal surgery unit at Jaslok Hospital between May 2013 and May 2014. The nutritional status was preoperatively assessed by using anthropometric parameters like body mass index (BMI), midarm circumference (MAC), and tissue skinfold thickness (TSFT). In addition, a subjective global assessment scale (SGA), serum albumin, and absolute lymphocyte count (ALC) were used. Patients with BMI <18.5, MAC <24 cm in males and <22 cm in females, and TSFT <10 mm were considered malnourished. Patients with serum albumin between 3 and 3.5 g/dl were considered mild, 2.4-2.9 g/dl was moderate, and <2.4 g/dl were severely malnourished. Patients with ALC between 1200 and 2000/cm were labelled mild, between 800 and 1199/cm were moderate, and <800/cm were severely malnourished. As per SGA, well-nourished had less than 5% weight loss or if more than 5%, with recent gain and improved appetite, mild/moderately malnourished had 5% to 10% weight loss with no gain, mild subcutaneous fat loss, and those severely malnourished had more than 10% weight loss, severe subcutaneous fat loss, and muscle wasting. Postoperative complications were graded as per the Clavien-Dindo classification. Patients with grades 1 and 2 complications were labelled as minor and the rest as major.

Result

Men in the age group of 40-60 years comprised the majority of the study population. The most frequent reason for admission was cholelithiasis. The overall incidence of malnutrition was 22.16%. Out of the 96 patients who had complications, 45 had minor and 41 had significant complications. Amongst the well-nourished, the incidence of complications was 26.62% of which the majority were minor complications. Severely malnourished patients had a high complication rate (63.38%); 32% out of the 63.38% developed significant complications. The majority of the patients suffering from severe malnutrition belonged to the sub-group with chronic pancreatitis and carcinoma of the pancreas. According to the chi-square analysis of the data, ALC, serum albumin, and SGA correlate with the postoperative complication rate with a p-value <0.05 as significant. On the contrary, BMI, MAC, and TSFT did not correlate with postoperative complications.

Conclusion

Preoperative malnutrition is common among patients undergoing abdominal surgeries in the urban private health care sector. Although there have been studies that have analyzed the incidence of malnutrition in patients undergoing oncological surgeries, there is limited literature on malnutrition among patients subjected to gastrointestinal surgeries. We conclude that simple bedside nutritional assessment tools like serum albumin, absolute lymphocyte count, and SGA can accurately identify malnourished patients preoperatively and are good predictors of postoperative complications. Hence, it is imperative to assess and attempt to improve the nutritional status of the patients preoperatively.

The clinical impact of malnutrition on the postoperative outcomes of patients undergoing gastrectomy for gastric cancer: Propensity score matched analysis of 2011-2017 hospital database

BACKGROUND & AIMS

Malnutrition is a prominent feature of gastric cancer patients who suffer from gastric outlet obstruction, impaired peristalsis, and cancer-mediated disruptions in metabolic hemostasis. In this study, we systematically evaluate the impact of malnutrition on the postoperative outcome of patients with gastric cancer undergoing gastrectomy.

METHODS

2011-2017 National Inpatient Sample was used to isolate patients with gastric cancer who underwent gastrectomy, who were stratified using malnutrition. The malnutrition-present cohort was matched to the malnutrition-absent controls using 1:1 propensity score-matching analysis, and compared to the following endpoints: mortality, length of stay (LOS), hospitalization costs, and postoperative complications.

RESULTS

5309 were identified to have undergone gastric resection procedure for gastric cancer, from which there were 1044 with malnutrition and 1044 matched controls. Malnourished patients had higher mortality (6.80 vs 3.83% p = 0.003, OR 1.83 95% CI 1.23-2.73), LOS (17.2 vs 11.4 d p < 0.001), costs ($197,702 vs $124,133 p < 0.001), and were more often discharged to rehabilitation facilities. Malnourished patients had higher rates of wound complications (3.64 vs 1.25% p < 0.001, OR 3.00 95% CI 1.59-5.66), infection (6.90 vs 3.26% p < 0.001, OR 2.20 95% CI 1.45-3.34), and respiratory failure (6.80 vs 3.64% p = 0.002, OR 1.93 95% CI 1.29-2.89). In multivariate analysis, malnourished patients had higher rates of mortality (p = 0.002, aOR 1.87 95% CI 1.25-2.80), length of stay (p < 0.001, aOR 1.52 95% CI 1.48-1.55), costs (p < 0.001, aOR 1.61 95% CI 1.61-1.61) despite controlling for non-matched hospital variables.

CONCLUSION

In this propensity score matched analysis, malnutrition is associated with increased postoperative mortality, LOS, and hospitalization costs in patients with gastric cancer undergoing gastric resection surgery.

Associations between Nutritional and Immune Status and Clinicopathologic Factors in Patients with Pancreatic Cancer: A Comprehensive Analysis

The aim of this study was to assess and analyze the nutritional status (NS) and immune status of pancreatic cancer (PC) patients. The retrospective analysis included 80 PC patients undergoing curative pancreatic resection in the Department of Digestive Tract Surgery of the Medical University (Katowice, Poland). Patients were divided by the tumor location (proximal vs. distal), age (≤65 years vs. >65 years), Nutritional Risk Score 2002 (NRS 2002) (<3 vs. ≥3), prognostic nutritional index (PNI) (<45 vs. ≥45), and the presence of postoperative complications (no-complication vs. complication) as well as the use of neoadjuvant chemotherapy (no neoadjuvant chemotherapy vs. neoadjuvant chemotherapy) into two subgroups, which were compared. Significantly higher weight loss was related to the proximal tumor location (p = 0.0104). Significantly lower serum total protein (p = 0.0447), albumin (p = 0.0468), hemoglobin (p = 0.0265) levels, and PNI (p = 0.03) were reported in older patients. The higher nutritional risk according to NRS 2002 was significantly associated with higher age (p = 0.0187), higher weight loss (p < 0.01), lower body mass index (BMI) (p = 0.0293), lower total lymphocyte count (p = 0.0292), longer duration of hospitalization (p = 0.020), neoadjuvant chemotherapy (p < 0.01), and preoperative biliary drainage (p = 0.0492). The lower PNI was significantly associated with higher weight loss (p = 0.0407), lower serum total protein and albumin concentration, lymphocyte count (p < 0.01) and higher neutrophil/lymphocyte (NLR), monocyte/lymphocyte (MLR), platelet/lymphocyte (PLR) ratios, and duration of hospitalization (p < 0.01). In the multiple logistic regression analysis, BMI ≥ 30 kg/m2 (OR: 8.62; 95% CI: 1.24-60.04; p = 0.029521) and NRS 2002 ≥ 3 (OR: 2.87; 95% CI: 0.88-9.33; p = 0.048818) predicted postoperative complications. In the multiple linear regression analysis, the higher NRS 2002 score was linked with the longer duration of hospitalization (b = 7.67948; p = 0.043816), and longer duration of postoperative hospitalization was associated with a higher complication rate (b = 0.273183; p = 0.003100). Nutritional impairment correlates with a systemic inflammatory response in PC patients. Obesity (BMI ≥ 30 kg/m2) and malnutrition (NRS 2002 ≥ 3) predict postoperative complications, which are associate with a longer hospital stay. Assessment of nutritional and immune status using basic diagnostic tools and PNI and immune ratio (NLR, MLR, PLR) calculation should be the standard management of PC patients before surgery to improve the postoperative outcome.

Relación del índice nutricional pronóstico con complicaciones y mortalidad en los pacientes con cáncer gástrico sometidos a gastrectomía en un hospital de tercer nivel de Bogotá, Colombia

Introducción. El cáncer gástrico es el quinto cáncer diagnosticado con mayor frecuencia y la tercera causa de muerte por cáncer en el mundo. En el tratamiento quirúrgico, la evidencia actual apoya las medidas preoperatorias e índices pronósticos para mejorar la supervivencia. El índice nutricional pronóstico, que une los valores de los linfocitos circulantes en sangre periférica con los de la albúmina sérica, ha presentado características de ser un marcador nutricional e inmunológico con valor predictivo sobre complicaciones y mortalidad. El objetivo de este estudio fue determinar la relación entre el índice nutricional pronóstico con las complicaciones y mortalidad en pacientes con cáncer gástrico sometidos a gastrectomía. Métodos. Se llevó a cabo un estudio observacional descriptivo, de corte transversal, con componente analítico, mediante la revisión retrospectiva de las historias clínicas. Resultados. Se analizaron 113 pacientes sometidos a gastrectomía total o subtotal. Se encontró asociación entre el índice nutricional pronóstico y la mortalidad; todos los pacientes que murieron tenían un índice menor o igual a 46. También se encontró asociación inversa entre el valor del índice y la presentación de complicaciones posoperatorias, como sepsis, peritonitis, fuga de la anastomosis y sangrado. Discusión. Similar a nuestro análisis, varios estudios plantean que un índice nutricional pronóstico bajo podría tener un valor predictivo sobre la frecuencia de complicaciones y supervivencia global en pacientes con cáncer gástrico llevados a cirugía. Conclusión. El índice nutricional pronóstico se asocia con la mortalidad y complicaciones posoperatorias en pacientes sometidos a gastrectomía por cáncer gástrico.

Low Food Consumption Interferes with the Nutritional Status of Surgical Patients with Neoplasia of the Gastrointestinal Tract

Nutritional support strongly influence the nutritional status of the surgical neoplastic patients. This study aimed to evaluate the influence of food consumption on the perioperative nutritional status of hospitalized patients with neoplasia of the upper (UGIT) and lower (LGIT) gastrointestinal tract. Methods: Observational, longitudinal, and prospective study. Data collected: food consumption, Subjective Global Assessment, anthropometry, laboratory tests. Results: Eighty patients were followed up: 43 (54%) in the UGIT and 37 (46%) in the LGIT. The consumption in the perioperative period was lower than the usual consumption in the UGIT and LGIT groups, respectively, of energy (14.2 ± 6.5; 22.8 ± 11.2 Kcal/kg/d, p < 0.001; 13.6 ± 1.2; 19.0 ± 2.0 Kcal/kg/d; p = 0.014), protein (1.1 ± 0.7; 0.6 ± 0.3 g/kg/d, p < 0.001; 0.8 ± 0.1; 0.5 ± 0.1 g/kg/d; p = 0.058), selenium, zinc and copper. Most patients presented in the UGIT and LGIT groups, respectively, worsening malnutrition and muscle depletion according to the Subjective Global Assessment (61.9%; 51.4%) and hypoalbuminemia, mainly in the UGIT in the postoperative. Conclusion: Low food consumption during the perioperative period associated with prolongation of the postoperative fasting period worsens the nutritional status of patients undergoing surgery of the gastrointestinal tract for neoplasia, especially in the UGIT group.

Nutrition Care Process Model Approach to Surgical Prehabilitation in Oncology

The nutrition care process is a standardized and systematic method used by nutrition professionals to assess, diagnose, treat, and monitor patients. Using the nutrition care process model, we demonstrate how nutrition prehabilitation can be applied to the pre-surgical oncology patient.

Core outcome set for surgical trials in gastric cancer (GASTROS study): international patient and healthcare professional consensus

BACKGROUND

Surgery is the primary treatment that can offer potential cure for gastric cancer, but is associated with significant risks. Identifying optimal surgical approaches should be based on comparing outcomes from well designed trials. Currently, trials report different outcomes, making synthesis of evidence difficult. To address this, the aim of this study was to develop a core outcome set (COS)-a standardized group of outcomes important to key international stakeholders-that should be reported by future trials in this field.

METHODS

Stage 1 of the study involved identifying potentially important outcomes from previous trials and a series of patient interviews. Stage 2 involved patients and healthcare professionals prioritizing outcomes using a multilanguage international Delphi survey that informed an international consensus meeting at which the COS was finalized.

RESULTS

Some 498 outcomes were identified from previously reported trials and patient interviews, and rationalized into 56 items presented in the Delphi survey. A total of 952 patients, surgeons, and nurses enrolled in round 1 of the survey, and 662 (70 per cent) completed round 2. Following the consensus meeting, eight outcomes were included in the COS: disease-free survival, disease-specific survival, surgery-related death, recurrence, completeness of tumour removal, overall quality of life, nutritional effects, and 'serious' adverse events.

CONCLUSION

A COS for surgical trials in gastric cancer has been developed with international patients and healthcare professionals. This is a minimum set of outcomes that is recommended to be used in all future trials in this field to improve trial design and synthesis of evidence.

Nutritional care of older people: Investigating nurses' attitudes in medical and surgical units

Background: Malnutrition in older people in hospitals leads to negative patient outcomes. Nurses often underestimate the problem, showing negative attitudes.Aims: To compare nurses' attitudes towards nutritional care of older people in surgical and medical wards. Design: Multicentre cross-sectional survey, conducted in January 2015.Methods: All nurses in surgical and medical wards in 10 hospitals in northern Italy were surveyed using the Staff Attitudes to Nutritional Nursing Care Geriatric Scale (SANN-G scale).Results: 799 out of 1,293 questionnaires were returned (61.8%). 23.2% (185) had a negative attitude, 56.6%(452) had a neutral attitude, and 20.2%(162), positive. Multivariate analysis showed no significant differences between medical and surgical wards (OR = 1.298; CI95% = .883-1.886, p = .18).Conclusions: It is necessary to raise nurses' awareness of poor nutritional care in both settings. More research is needed within the barriers to nutritional care.Impact statement: Strategies such as education and more clearly defined nutritional responsibilities are needed to improve nurses' attitudes.

Malnutrition screening tools in gastrointestinal cancer: A systematic review of concurrent validity

OBJECTIVE

Malnutrition is a significant problem in gastrointestinal (GI) cancer, and accurate screening and identification is essential to ensure appropriate nutrition intervention. This study aims to determine current evidence for concurrent validity of malnutrition screening tools in GI cancer.

METHODS

A systematic review was undertaken according to PRISMA guidelines, using four databases. Studies investigating the concurrent validity of malnutrition screening tools against a reference standard of Patient Generated Subjective Global Assessment (PG-SGA) or Subjective Global Assessment (SGA) in adult patients with GI cancer were identified. Screening, quality assessment using the QUADAS-2 checklist, and data extraction were performed by two independent reviewers. Concurrent validity ratings were applied using predefined criteria.

RESULTS

Six studies investigating concurrent validity of the Nutrition Risk Index (NRI), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST) and Nutrition Risk Screening 2002 criteria (NRS-2002) were included. There was variation in concurrent validity ratings ranging from poor-good for all tools, depending on treatment type, stage and population characteristics.

CONCLUSION

Recommendations regarding the use of one tool over another could not be made. However, in the absence of a clear recommendation specific to GI cancer, screening tools that are well validated in general clinical populations should be utilised. The MST can be recommended based on validity data against the PG-SGA and SGA from other oncology populations. If indicated, malnutrition screening should then be followed by thorough nutritional assessment.

Sarcopenia in Patients With Normal Body Mass Index Is an Independent Predictor for Postoperative Complication and Long-Term Survival in Gastric Cancer

Malnutrition in patients with gastric cancer (GC) with normal body mass index (BMI) is often ignored. This study aimed to explore the role of sarcopenia in predicting postoperative complication and long-term survival in patients with GC with normal BMI. We included patients with normal BMI (18.5 kg/m2  ≤ BMI < 23 kg/m2 ) who underwent radical gastrectomy between July 2014 and December 2016. Sarcopenia was assessed by muscle mass, handgrip strength, and gait speed. Kaplan-Meier survival analysis was used to analyze the association between sarcopenia and the prognosis of patients with GC. Univariate and multivariate analyses were used to identify risk factors contributing to postoperative complications and long-term survival. Overall, 267 patients with GC with normal BMI were included in this study; of which 49 (18.35%) patients were diagnosed with sarcopenia. Patients with sarcopenia had higher incidence of a major postoperative complication, longer postoperative hospital stays, and greater hospital costs. The Kaplan-Meier survival analysis showed that patients with sarcopenia had poorer overall survival than non-sarcopenia patients. Univariate and multivariate analyses showed that sarcopenia was an independent predictor for postoperative complication and long-term survival in such patients. Sarcopenia is an independent predictor for postoperative complications and long-term survival in patients with normal BMI after radical gastrectomy for GC. We recommend that patients with normal BMI should perform nutritional risk screening by sarcopenia.

Different muscle mass indices of the Global Leadership Initiative on Malnutrition in diagnosing malnutrition and predicting survival of patients with gastric cancer

OBJECTIVE

Malnutrition is common and related to negative prognosis in patients with gastric cancer (GC). The Global Leadership Initiative on Malnutrition (GLIM), a novel consensus for the diagnosis of malnutrition, was proposed recently. However, the roles of GLIM in diagnosing malnutrition and predicting overall survival (OS) in patients with GC have been unclear.

METHOD

We conducted a multicenter, observational cohort study including 877 hospitalized patients with GC 2013 through 2018. Different anthropometric measurements were compared to assess reduced muscle mass. Kaplan-Meier curves and multivariate Cox regression were used to analyze the relationship between GLIM-defined malnutrition and the OS of patients with GC. Independent prognostic variables were incorporated to develop a nomogram for individualized survival prediction. The calibration curve was used to determine the predictive accuracy and discriminatory capacity of the nomogram. In addition, 219 patients with GC were enrolled for external validation.

RESULTS

A total of 464 (53%) patients with GC were diagnosed with malnutrition. Patients diagnosed with severe malnutrition based on either midarm circumference or body weight-standardized hand grip strength had a shorter median survival time (16.7 mo; interquartile range, 8.4-32.7 mo) and a higher hazard ratio (HR, 1.49; 95% CI, 1.15-1.92; P = 0.002). Severe malnutrition was an independent risk factor for OS (HR, 1.32; 95% CI, 1.02-1.71; P = 0.038). The GLIM nomogram showed good performance in predicting 3-y survival in patients with GC.

CONCLUSIONS

Our findings support the effectiveness of GLIM in diagnosing malnutrition and predicting OS in patients with GC.

Assessment of adherence to oral nutritional supplementation and exploration of barriers and facilitators in patients after gastric cancer surgery: a mixed methods study protocol

INTRODUCTION

Postoperative malnutrition is a major issue in patients with gastric cancer. The European Society for Clinical Nutrition and Metabolism recommends oral nutritional supplements (ONS) as a first-line nutritional therapy to prevent malnutrition in patients with cancer. However, adherence to ONS is unsatisfactory. The overall aim of this study was to evaluate the adherence of patients with gastric cancer to ONS and to explore the promoting and hindering factors.

METHODS AND ANALYSIS

In this study, we will use mixed methods with an explanatory sequential approach for data collection and analysis. In the first phase, a 12-week longitudinal study will be performed to identify changes in trends of oral nutritional supplementation adherence in 135 patients with gastric cancer, the impact of adherence on nutritional indicators and clinical outcomes and ONS adherence-related factors. The primary endpoints include patient adherence to ONS, weight, body mass index and grip strength followed by 30-day readmission rate, complications and adverse reactions. In the second stage, qualitative research will be implemented to provide in-depth insight into the quantitative results. Finally, quantitative and qualitative results will be combined for analysis and discussion to put forward suggestions for improving patients' ONS adherence.

ETHICS AND DISSEMINATION

This research protocol has been approved by the Ethics Committee of the School of Nursing, Jilin University, China (No. 2019101601). Results will be disseminated in peer-reviewed journals and conferences, and sent to participating practices.

Nutritional Risk and Assessment for Patients with Cancer Pain

BACKGROUND

The incidence of nutritional risk and malnutrition are high in patients with cancer pain. It is very important to choose an effective tool to identify these patients promptly. However, few studies have discussed this issue. The primary objective of this study is to clarify the similarities and differences between the two nutritional screening and assessment tools, and to estimate the anthropometry and biochemical indicators of the patients with cancer pain, with a view to provide help for treatment of these patients.

METHOD

Data of 146 patients with cancer pain were collected from August 2018 to May 2019 in the Pain Therapy Department of Tianjin Cancer Hospital. The information of numerical rating scale (NRS), nutritional risk screening-2002 (NRS-2002), patient-generated subjective global assessment (PG-SGA), anthropometry and biochemical indicators were collected for pain assessment, nutritional risk screening, and nutritional status assessment.

RESULTS

NRS scores had a positive correlation with NRS-2002 (R = 0.273, P = 0.001) and PG-SGA (R = 0.341, P = 0.000) separately. NRS-2002 and PG-SGA had a significant positive correlation with each other (R = 0.468, P = 0.000). NRS-2002 was finished in a shorter time period (4.2 ± 0.8 min vs. 12.8 ± 0.8 min, P = 0.001), while PG-SGA had a higher detection rate of malnutrition (86.3% vs. 65.8%). In the stepwise multiple regression analysis, NRS (0.258, P = 0.001), PA (-0.297, P = 0.000), TP (0.178, P = 0.030) are the indicators of NRS-2002; and NRS (0.317, P = 0.000), PA (β = 0.288, P = 0.000) and BMI (-0.281, P = 0.000) are the related variables of PG-SGA. The kappa coefficient was lower than 0.4 (kappa value = 0.396) when choosing the score of NRS-2002 ≥ 3 and PG-SGA ≥ 9 as the diagnostic criteria. If choosing the score of NRS-2002 ≥ 2 and PG-SGA ≥ 9, both the correlation coefficient (R = 0.699, P = 0.000) and the kappa coefficient (kappa value = 0.698, P = 0.000) became more coefficient.

CONCLUSIONS

Both NRS-2002 and PG-SGA could identify patients with nutritional risk and malnutrition accurately. NRS-2002 is simpler and takes less time to finish, while PG-SGA is more cumbersome with a higher detection rate of malnutrition. NRS, PA, TP and BMI are the most important reference indicators predicting on nutritional risk index and malnutrition status. We recommend NRS-2002 ≥ 2 as the diagnostic criteria in order to avoid missing the patients with nutritional risk.

Development and validation of nomograms for the prediction of low muscle mass and radiodensity in gastric cancer patients

BACKGROUND

The skeletal muscle mass index (SMI) and skeletal muscle radiodensity (SMD) are important components of sarcopenia and malnutrition. However, their assessment requires additional resources in cancer patients, which is inconvenient for the early detection of sarcopenia and malnutrition.

OBJECTIVES

This study aimed to develop and validate nomograms for the prediction of low muscle mass and muscle radiodensity and to examine the application value of the nomograms in the diagnoses of sarcopenia and malnutrition.

METHODS

A total of 1315 patients diagnosed with gastric cancer between July 2014 and May 2019 were included. Random resampling with an 80/20 split ratio was performed to obtain a training cohort (n = 1056) and a validation cohort (n = 259). Nomograms were separately constructed for low SMI (LSMI) and low SMD (LSMD) in the training cohort based on prospectively collected preoperative data. The performance of the nomograms was assessed using the AUC, calibration curve, and Hosmer-Lemeshow test. The application values of the nomograms in the diagnoses of sarcopenia and malnutrition were also evaluated.

RESULTS

Age, BMI, hemoglobin concentration, and gait speed were included in the nomogram for LSMI predictions. These variables, in addition to sex, were included in the nomogram for LSMD predictions. The diagnostic nomograms exhibited good discrimination, with AUCs of 0.818 (95% CI, 0.791-0.845) for the LSMI nomogram and 0.788 (95% CI, 0.761-0.815) for the LSMD diagnostic nomogram in the training cohort. Calibration was also excellent. The agreement ratios between the nomograms and actual observations in the total population were 92.3% and 95.6% for sarcopenia and malnutrition, respectively. Prognostic nomograms exhibited similar performance in the validation cohort.

CONCLUSIONS

Diagnostic nomograms consisting of preoperative factors can successfully predict LSMI and LSMD. These models facilitate early identification and timely interventions for at-risk populations.

Does nutritional status affect treatment tolerability, chemotherapy response and survival in metastatic gastric cancer patients? Results of a prospective multicenter study in Turkey

BACKGROUND

The possible impact of malnutrition on the efficacy and tolerability of modern chemotherapy for metastatic gastic adenocarcinoma (mGC) patients is unclear. With this study, we aimed to represent the possible impact of malnutrition on the efficacy and tolerability of chemotherapy, and also on the overall survival of mGC patients.

METHODS

In this prospective multicenter study, we collected demographic, oncological and nutritional data of our mGC patients. The nutritional status of patients were assessed with the Nutritional Risk Index (NRI), Body Mass Index (BMI) and weight loss percentage within 21-day period, between the chemotherapy cycles. All of these parameters along with toxicity assessment were evaluated after each courses of chemotherapy in order to determine inter-treatment weight loss. NRIs were calculated with a formula as follows; [1.519 × serum albumin level(g/L) + 41.7 × current weight/basic weight]. Patients were classified as having 'no malnutrition' (NRI > 97.5), 'moderate malnutrition' (97.5 ≥ NRI ≥ 83.5) or 'severe malnutrition' (NRI < 83.5). Drug-induced toxicities and treatment responses were evaluated via National Cancer Institute CTCAE version 4.0 and RECIST Criteria 1.1, respectively.

RESULTS

One hundred and sixteen mGC patients were enrolled into the study. Median age was 60 years with range 32-83. Primary location of the tumor was antrum in 40% of the patients and of which 24% had undergone primary tumor resection. Ninety-eight percent of the patients had WHO performance status 0 or 1. Malnutrition was diagnosed in 67% of the patients and was severe in 31% of them. All patients received chemotherapy as first-line setting. Severe malnutrition was not associated with chemotherapy responses (p = 0.57). Moderate/severe malnutrition was associated with more cytopenia, nausea/vomiting, diarrhea, neuropathy, (p < 0.05 for all parameters). Moderate/severe malnutrition is associated with worser non-hematological toxicities (p = 0.038). Forty-one percent of patients died during the follow up period (Median: 138 days, range: 21-378). Malnutritional level was associated with significantly reduced overall survival. Severe malnutrition was associated with shorter median overall survival (74 days (95% CI, 20.7-111.0) vs. 237 (95% CI, 148.4-325.6) in none/moderate groups, p = 0.007).

CONCLUSIONS

In mGC patients, moderate/severe malnutrition is associated with worse non-hematological toxicities. Severe malnutrition is also associated with reduced overall survival.

Prognostic Value of Restaging F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography to Predict 3-Year Post-Recurrence Survival in Patients with Recurrent Gastric Cancer after Curative Resection

OBJECTIVE

The aim of this study was to investigate the prognostic value of the maximum standardized uptake value (SUV_max) measured while restaging with F-18 fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) to predict the 3-year post-recurrence survival (PRS) in patients with recurrent gastric cancer after curative surgical resection.

MATERIALS AND METHODS

In total, 47 patients with recurrent gastric cancer after curative resection who underwent restaging with ¹⁸F-FDG PET/CT were included. For the semiquantitative analysis, SUV_max was measured over the visually discernable ¹⁸F-FDG-avid recurrent lesions. Cox proportional-hazards regression models were used to predict the 3-year PRS. Differences in 3-year PRS were assessed with the Kaplan-Meier analysis.

RESULTS

Thirty-nine of the 47 patients (83%) expired within 3 years after recurrence in the median follow-up period of 30.3 months. In the multivariate analysis, SUV_max (p = 0.012), weight loss (p = 0.025), and neutrophil count (p = 0.006) were significant prognostic factors for 3-year PRS. The Kaplan-Meier curves demonstrated significantly poor 3-year PRS in patients with SUV_max > 5.1 than in those with SUV_max ≤ 5.1 (3-year PRS rate, 3.5% vs. 38.9%, p < 0.001).

CONCLUSION

High SUV_max on restaging with ¹⁸F-FDG PET/CT is a poor prognostic factor for 3-year PRS. It may strengthen the role of ¹⁸F-FDG PET/CT in further stratifying the prognosis of recurrent gastric cancer.

Feasibility of substituting handgrip strength for muscle mass as a constituent standard in the Global Leadership Initiative on Malnutrition for diagnosing malnutrition in patients with gastrointestinal cancers

OBJECTIVES

The aim of this study was to determine the feasibility of substituting handgrip strength (HGS) for muscle mass as a constituent in the Global Leadership Initiative on Malnutrition (GLIM) to diagnose malnourished patients with gastrointestinal (GI) cancer.

METHODS

The study included 2209 patients diagnosed with GI cancer from two centers. All patients were evaluated for nutritional risk using Nutritional Risk Screening 2002 within 24 h of admission. The GLIM consensus was then used to diagnose malnourished patients. The evaluation of muscle mass as one of the constituents contained in the GLIM consensus was measured by computed tomography presented as skeletal muscle mass index (SMI) and HGS, respectively. Consistency test was carried out to evaluate the diagnostic value of SMI and HGS.

RESULTS

There were 1042 (47.2%) cases of gastric cancer and 1167 (52.8%) cases of colorectal cancer. Among these cases were 768 patients (34.8%) at nutritional risk. Furthermore, 603 (27.3%) and 593 patients (26.8%) were diagnosed with malnutrition in the GLIM (SMI) group and the GLIM (HGS) group, respectively, and 544 (24.6%) patients in the two groups overlapped. The consistency test results showed that the κ value in the GLIM (HGS) group compared with the GLIM (SMI) group was 0.881 (P < 0.001) in patients with gastric cancer and 0.872 (P < 0.001) in those with colorectal cancer.

CONCLUSION

HGS can be a substitute for muscle mass as a constituent in the diagnostic criteria of GLIM in patients with GI cancer.

Biochemical parameters and nutritional status of surgical patients with gastrointestinal cancer: a literature review

This is an integrative literature review with the objective of identifying the relationship between biochemical parameters and the nutritional status of surgical patients with cancer of the gastrointestinal tract, developed in April 2019, encompassing the databases SCOPUS (Elsevier), PubMed Central® (PMC), and the Cochrane Virtual Health Library (BVS). We used the terms "Gastrointestinal Neoplasm" AND "Nutritional Status" AND "Blood Chemical Analysis" with the aid of the Academical software after the protocol validation. Out of 147 articles analyzed, seven were included in the review, as they met the inclusion criteria. There were relevant associations between biochemical parameters and nutritional status. Impaired nutritional status can negatively influence the postoperative outcome. The monitoring of interdisciplinary teams can assist in the recovery of these patients and prevent unfavorable outcomes.

Nutritional screening tools for adult cancer patients: A hierarchical Bayesian latent-class meta-analysis

BACKGROUND & AIMS

Cancer treatment requires attentiveness to its broader effect on the body. Cancer's effect on appetite, strength, and body composition is contained in the summary term malnutrition. The tools used to detect malnutrition are a critical part of effective cancer care. In clinical care, selection of any specific tool is random. The relative validity of these tools have not been systematically compared. Using hierarchical Bayesian latent-class meta-analysis methods, this report compares three tools used for adult cancer patients - the Mini Nutritional Assessment (MNA), the Nutritional Risk Screening 2002 (NRS-2002) and the Patient Generated Subjective Global Assessment (PG-SGA).

METHOD

Drawing from English and Chinese language databases, a broad pool of eligible studies were identified for further selection and assessment. Using the hierarchical summary receiver operating characteristic (HSROC) model, pooled sensitivity, specificity, and other measurements the accuracy of the three tools were compared.

RESULT

A total of 37 eligible studies involving the MNA, NRS-2002 and PG-SGA were included in this meta-analysis. The pooled sensitivity was 0.910 (95% CI: 0.763 to 0.970) for MNA, 0.747 (95% CI: 0.680 to 0.804) for NRS-2002, and 0.964 (95% CI: 0.913 to 0.986) for PG-SGA. The pooled specificity was 0.720 (95% CI: 0.623 to 0.800) for MNA, 0.854 (95% CI: 0.808 to 0.891) for NRS-2002, 0.905 (95% CI: 0.807 to 0.956) for PG-SGA, respectively. The back-calculated likelihood ratio (LR) showed that MNA had a low negative likelihood ratio (LR^-), NRS-2002 corresponded to a high positive likelihood ratio (LR⁺) and PG-SGA represented the best LR⁺ and LR^-.

CONCLUSIONS

While there is no standard approach to assessment of malnutrition, the PG-SGA has the best diagnostic performance with cancer patients. Further work is needed to refine the utility of these tools in larger clinical samples.

Combination of Haemoglobin and Prognostic Nutritional Index Predicts the Prognosis of Postoperative Radiotherapy for Esophageal Squamous Cell Carcinoma

Purpose

To investigate the predictive effect of the combined markers of haemoglobin and prognostic nutritional index (PNI) on the long-term survival of patients undergoing postoperative radiotherapy for esophageal squamous cell carcinoma (ESCC).

Patients and Methods

A total of 238 patients were included in this retrospective analysis. PNI was calculated as the serum albumin level (g/L) + 5 × absolute lymphocyte count, and the cut-off values of PNI and haemoglobin were calculated by receiver operating characteristic (ROC) curve analysis. Then, we combined haemoglobin and PNI, named the H-PNI score, as a predictor of tumour prognosis. The patients were divided into three groups: H-PNI score of 2 (having both hyper-haemoglobin and high PNI), H-PNI score of 1 (having one of these haematological abnormalities), and H-PNI score of 0 (having neither hyper-haemoglobin nor high PNI). The overall survival (OS) rate was calculated using the Kaplan–Meier method, and survival differences between groups were evaluated using the Log rank test. Cox proportional hazards models were used for univariate and multivariate analyses. P values <0.05 indicated statistical significance.

Results

The cut-off values of haemoglobin and PNI were 132.5 (g/L) and 46.55, respectively. Kaplan–Meier analysis showed that patients with high haemoglobin and PNI levels had a significantly better prognosis than those with low haemoglobin and PNI levels (P = 0.015 and P = 0.002, respectively). Similarly, the survival rate was significantly lower in patients with an H-PNI score of 0 than in those with an H-PNI score of 1–2 (P=0.000). Univariate analysis indicated that differentiation, T and N classification, and H-PNI score were significantly associated with OS. Finally, differentiation (P=0.002), T and N classification (P=0.000), and H-PNI score (P=0.01) were independent prognostic factors for ESCC patients undergoing postoperative radiotherapy.

Conclusion

The H-PNI score was an independent prognostic factor for ESCC patients undergoing postoperative radiotherapy.

Predicting Postoperative Events in Patients With Gastric Cancer: A Comparison of Five Nutrition Assessment Tools

BACKGROUND/AIM

We compared the adequacy of five nutrition assessment tools with respect to their predictive value in patients with locally advanced gastric cancer (GC) receiving radical surgery.

PATIENTS AND METHODS

Five nutrition assessment tools-Glasgow prognostic score (GPS), malnutritional universal screening tool (MUST), nutritional risk screening, patient generated subjective global assessment (PG-SGA), and prognostic nutritional index (PNI)-were assessed preoperatively for stage III GC patients. The correlation between postoperative events and nutritional status was further analyzed.

RESULTS

Most of the nutritional tools accurately predicted length of hospital stay and grade 3 or higher surgical complications, while only the GPS correlated with 30-day readmission and surgical complications. The PG-SGA performed the poorest among the five tools and failed to predict any postoperative event.

CONCLUSION

The application of GPS is recommended as a prognostic index for patients with locally advanced GC prior to radical surgery.

Enteral nutritional support in patients undergoing chemoradiotherapy for esophageal carcinoma

Esophageal cancer patients are at a high risk of malnutrition. Both the disease itself and chemoradiotherapy will lead to the deterioration of nutritional status. The development of nutritional oncology promotes the application of enteral nutrition in tumor patients. Through nutritional support, prognosis is improved and the incidence of adverse chemoradiotherapy reactions is reduced, especially in those with head and neck or esophageal cancer. This review summarizes enteral nutritional support in esophageal cancer patients undergoing chemoradiotherapy in recent years, including a selection of nutritional assessment tools, the causes and consequences of malnutrition in esophageal cancer patients, types of access and effects of enteral nutrition. More patients with esophageal cancer will benefit from the development of enteral nutrition technology in the future.
