Effect of malnutrition as defined by the Global Leadership Initiative on Malnutrition criteria on compliance of adjuvant chemotherapy and relapse-free survival for advanced gastric cancer

The impact of preoperative skeletal muscle loss on the completion of S-1 adjuvant chemotherapy for gastric cancer

PURPOSE

Body weight loss after surgery for gastric cancer is related to S-1 compliance and it also affects the prognosis. However, it is unclear whether the preoperative skeletal muscle mass affects S-1 completion for gastric cancer. We investigated the impact of preoperative skeletal muscle mass loss on the completion of S-1 adjuvant chemotherapy for gastric cancer.

METHODS

We retrospectively analyzed data from 53 patients who underwent curative gastrectomy followed by adjuvant S-1 monotherapy for pStage II-III gastric cancer between 2012 and 2021 at our hospital. The psoas muscle mass index (PMI) was used as the index for preoperative skeletal muscle mass.

RESULTS

Thirty-six patients completed S-1 treatment and 17 discontinued treatment. The patients who completed S-1 treatment had a longer overall survival than those who discontinued treatment (log-rank test, p = 0.043). According to a univariate analysis, the patients in the discontinuation group had a significantly lower preoperative body mass index (< 22.9 kg/m2, p = 0.005) and a higher rate of adverse events (grade 2 or higher, p < 0.001) than those in the completion group. According to a multivariate analysis, preoperative PMI (HR 3.563, p = 0.030) was an independent predictive factor for S-1 completion.

CONCLUSION

Preoperative skeletal muscle loss might therefore prevent the completion of adjuvant chemotherapy S-1 in patients with gastric cancer.

Nutritional support after hospital discharge reduces long-term mortality in patients after gastric cancer surgery: Secondary analysis of a prospective randomized trial

BACKGROUND AND AIMS

Nutritional support after hospital discharge was found to enhance the nutritional condition of patients after cancer surgery. However, the effect of such support on long-term clinical outcomes is controversial. We thus investigated the effect of nutritional support after hospital discharge on long-term clinical outcomes in patients after gastric cancer surgery.

METHODS

This was a secondary analysis on individuals at nutritional risk who underwent gastric cancer surgery and were included in a randomized controlled trial. The intervention group received oral nutritional supplements combined with dietary advice, and the control group received dietary advice alone. The long-term mortality (primary outcome) and other clinical outcomes were compared between the groups.

RESULTS

In total, 321 patients were included in this analysis, with a median follow-up duration of 60.5 months. According to the Nutritional Risk Screening 2002 (NRS 2002), the presence of nutritional risk was found to be a significant predictor of death. This association remained independent even after adjusting for age, sex, comorbidity, and American Joint Committee on Cancer stage. The adjusted hazard ratio for mortality increased by 1.30 (95% confidence interval [CI] 1.05-1.60, P = 0.016) for each additional point rise in NRS. During the follow-up, a total of 64 individuals (39.5%) in the intervention group and 81 patients (50.9%) in the control group died. Consequently, the adjusted hazard ratio for mortality between the two groups was 0.69 (95% CI 0.50-0.96, P = 0.026). The results of interaction tests did not yield statistically significant variations in fatality rates across the age, sex, comorbidity, NRS, and American Joint Committee on Cancer stage subgroups. Nutritional support after hospital discharge significantly improved handgrip strength (adjusted coefficient 5.05, 95% CI 3.01-7.08, P = 0.000) in addition to other functional outcomes.

CONCLUSIONS

Nutritional support after hospital discharge reduced long-term mortality and improved handgrip strength among patients at nutritional risk after gastric cancer surgery. The current investigation provides evidence for the recommendation of nutritional support, for post-surgery patients after hospital discharge, in cancer management guidelines.

Comparison of three objective nutritional screening tools for identifying GLIM-defined malnutrition in patients with gastric cancer

OBJECTIVE

This study aimed to compare three objective nutritional screening tools for identifying GLIM-defined malnutrition in patients with gastric cancer (GC).

METHOD

Objective nutritional screening tools including geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and controlling nutritional status (CONUT) score, were evaluated in patients with GC at our institution. Malnutrition was diagnosed according to the GLIM criteria. The diagnostic value of GNRI, PNI, and COUNT scores in identifying GLIM-defined malnutrition was assessed by conducting Receiver Operating Characteristic (ROC) curves and calculating the area under the curve (AUC). Additionally, sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were determined. The Kappa coefficient (k) was used to assess agreement between three objective nutritional screening tools and GLIM criteria.

RESULTS

A total of 316 patients were enrolled in this study, and malnutrition was diagnosed in 151 (47.8%) patients based on the GLIM criteria. The GNRI demonstrated good diagnostic accuracy (AUC = 0.805, 95% CI: 0.758-0.852) for detecting GLIM-defined malnutrition, while the PNI and COUNT score showed poor diagnostic accuracy with AUCs of 0.699 (95% CI: 0.641-0.757) and 0.665 (95% CI: 0.605-0.725) respectively. Among these objective nutritional screening tools, the GNRI-based malnutrition risk assessment demonstrated the highest specificity (80.0%), accuracy (72.8%), PPV (74.8%), NPV (71.4%), and consistency (k = 0.452) with GLIM-defined malnutrition.

CONCLUSIONS

Compared to PNI and COUNT scores, GNRI demonstrated superior performance as an objective nutritional screening tool for identifying GLIM-defined malnutrition in GC patients.

Summary of Evidence on Nutritional Management for Patients Undergoing Chemotherapy

OBJECTIVE

This paper aims to consolidate the most robust evidence on nutritional strategies for patients undergoing chemotherapy, offering evidence-based guidance for clinical practice. The review highlights critical evidence gaps in nutritional therapy for advanced gastric cancer (AGC) patients undergoing systemic therapy, integrating findings from both prospective and retrospective studies.

METHOD

According to the "6S" evidence resource pyramid model, clinical decision-making tools, guidelines, expert consensus, and systematic reviews on nutritional management for chemotherapy patients were systematically retrieved from national and international databases. The methodological quality of the selected literature was evaluated using AGREE II for guidelines, the JBI Evidence-Based Healthcare Center's standards for systematic reviews, and expert consensus developed by evidence-based practice experts.

RESULTS

A total of 47 articles were analyzed, consisting of 12 guidelines, 12 expert consensus statements, and 23 systematic reviews. The findings were categorized into five dimensions: interdisciplinary collaboration, nutritional screening and assessment, nutritional requirements, nutritional therapy, and discharge and follow-up, resulting in the identification of 62 pieces of relevant evidence.

CONCLUSIONS

The study provides comprehensive, evidence-based recommendations for nutritional management in chemotherapy patients. Application of the evidence should be adapted to specific clinical scenarios, patient conditions, preferences, and expert judgment to ensure both feasibility and relevance in clinical practice.

CONTRIBUTIONS

This review consolidates diverse nutritional management strategies into a unified framework, addressing evidence gaps in AGC under systemic therapy. Integrating prospective and retrospective studies with interdisciplinary insights provides evidence-based recommendations to enhance patient care through personalized and standardized approaches.

Validity of the Global Leadership Initiative on Malnutrition criteria in East Asian patients with gastric cancer: a comprehensive narrative review

Background

Malnutrition is a significant public health issue for patients with gastric cancer, particularly in East Asia, the region most affected globally. In response to the absence of adequate tools for assessing nutritional status, the Global Leadership Initiative on Malnutrition (GLIM) criteria were established in 2018, aiming to standardize the diagnosis of malnutrition. However, there is no consensus on the value of GLIM criteria for evaluating the nutritional status of patients with gastric cancer in East Asia. Given these facts, our study aimed to assess the validity of the GLIM criteria in East Asian patients with gastric cancer.

Methods

We conducted a rapid critical review of available literature, summarizing the existing problems in GLIM applications and possible improvement directions. After systematically summarizing the literature published in PubMed, Web of Science, and Cochrane Library, a total of 13 articles involving 7,679 cases were included in this study.

Results

The results indicated a lack of sufficient data on sensitivity and specificity to fully validate the GLIM criteria for diagnosing malnutrition in East Asian patients with gastric cancer. Additionally, some studies have reported moderate agreement between the GLIM and the PG-SGA. Furthermore, malnutrition defined by GLIM is a risk factor for short and long-term outcomes in East Asian patients with gastric cancer. However, the prognostic effect of moderate malnutrition on these patients remains controversial.

Conclusion

Despite being in the early application stages, GLIM has shown promising potential in diagnosing and predicting the prognosis of malnutrition. However, future research should incorporate more comprehensive validity parameters, including sensitivity, specificity, and PPV/NPV, to achieve a more thorough understanding of GLIM's diagnostic efficacy. Furthermore, further optimization of GLIM is necessary to address the needs of more diverse populations and situations.

Routine assessment of nutritional, functional and inflammatory criteria in patients with cancer: A systematic review

BACKGROUND

The review discusses the significant impact of cancer on patients, particularly focusing on cachexia - a condition marked by weight and lean tissue loss. This condition critically affects the nutritional status, quality of life, and treatment outcomes of cancer patients.

RESEARCH QUESTION

The review seeks to understand the effectiveness and necessity of routine clinical monitoring of cancer cachexia, and how it can aid in better therapeutic interventions.

METHODS

The systematic review followed a pre-defined protocol based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)statement. A systematic search using specific keywords was conducted in PubMed and EMBASE databases on October 24, 2023, supplemented by citations from the original papers. The selection process involved screening titles and abstracts for relevance.

RESULTS

The review finds varying levels of effectiveness in the different measurement criteria used for monitoring cachexia. It highlights the potential of the Global Leadership Initiative on Malnutrition (GLIM) framework in defining and managing cancer cachexia, though noting some challenges in standardisation and implementation of measurements.

CONCLUSION

The present systematic review highlights the variability and lack of standardization in the application of GLIM criteria for monitoring cachexia in cancer patients. Despite these challenges, it will be important to determine the most efficacious clinically routine nutritional and inflammation assessments in the routine application of GLIM criteria assessment.

Combination of handgrip strength and high-sensitivity modified Glasgow prognostic score predicts survival outcomes in patients with colon cancer

Objective

Handgrip strength (HGS) and the high-sensitivity modified Glasgow prognostic score (HS-mGPS) are associated with the survival of patients with cancer. However, no studies have investigated the combined effect of HGS and HS-mGPS on the overall survival (OS) of patients with colon cancer.

Methods

Prospective follow-up data of colon cancer patients undergoing radical resection from April, 2016 to September, 2019 were retrospectively collected. We combined the HGS and HS-mGPS to create a new composite index, HGS-HS-mGPS. The hazard ratio (HR) and 95% confidence interval (CI) were calculated using Cox regression models to assess the association between variables and OS. Risk factors on OS rates were investigated by Cox analyses and the nomogram was constructed using significant predictors and HGS-HS-mGPS. The predictive performance of the nomogram was evaluated by receiver operating characteristic curve and calibration curve.

Results

This study included a total of 811 patients, of which 446 (55.0%) were male. The HGS optimal cut-off values of male and female patients were 28.8 and 19.72 kg, respectively. Multivariate analysis revealed that low HGS and high HS-mGPS were independent risk factors of colon cancer after adjusting confounders (adjusted HR = 3.20; 95% CI: 2.27-4.50; p < 0.001 and adjusted HR = 1.55; 95% CI: 1.12-2.14; p = 0.008 respectively). Patients with low HGS and high HS-mGPS had a 10.76-fold higher mortality risk than those with neither (adjusted HR = 10.76; 95% CI: 5.38-21.54; p < 0.001). A nomogram predicting 1-, 3-, and 5 year OS was constructed based on three clinicopathologic prognostic factors. Importantly, incorporating HGS-HS-mGPS into the nomogram model meaningfully improved the predictive performance. The decision curve analyses demonstrated the application value of the HGS-HS-mGPS nomogram for predicting OS of patients with colon cancer.

Conclusion

HGS-HS-mGPS is associated with the survival of patients with colon cancer. These findings indicate the usefulness of HGS and HS-mGPS measurements in clinical practice for improving patient assessment, cancer prognosis, and precise intervention.

Adipose Tissue Quantification Improves the Prognostic Value of GLIM Criteria in Advanced Gastric Cancer Patients

The present study investigated whether the risk of recurrence after curative surgery could be further stratified by combining the Global Leadership Initiative on Malnutrition (GLIM) criteria and changes in subcutaneous (SAT) and visceral (VAT) adipose tissue mass after surgery in patients with advanced gastric cancer (AGC). This study retrospectively analyzed 302 patients with AGC who underwent curative surgery. Based on the GLIM criteria, patients were classified into malnourished and non-malnourished groups. The cross-sectional areas of SAT and VAT were measured from preoperative and 6-month post-operative computed tomography (CT) images. Multivariate survival analyses demonstrated that GLIM-defined malnutrition (p = 0.008) and loss of VAT after surgery (p = 0.008) were independent risk factors for recurrence-free survival (RFS). Evaluation of the prognostic value of combining the two independent predictors showed that malnourished patients with a marked loss of VAT had the worst 5-year RFS rate of 35.2% (p < 0.001). Preoperative GLIM-defined malnutrition and a loss of VAT during the first 6 months after surgery were independent predictors for RFS in patients with AGC. Changes in the VAT area after surgery could further enhance the prognostic value of the GLIM criteria for predicting the risk of gastric cancer recurrence.

Exploring the association between inflammatory biomarkers and gastric cancer development: A two-sample mendelian randomization analysis

This study aimed to elucidate the potential causative links between inflammatory biomarkers and gastric cancer risk via a two-sample Mendelian randomization approach. Leveraging genome-wide association study (GWAS) data, we conducted a two-sample Mendelian randomization analysis. Instrumental variable selection for inflammatory markers - namely, tissue factor, monocyte chemotactic protein-1, E-selectin, interleukin 6 receptor, and fatty acid-binding protein 4 - was informed by SNP data from the IEU database. Strongly associated SNPs served as instrumental variables. We applied a suite of statistical methods, including Inverse Variance Weighted (IVW), Weighted Median Estimator (WME), MR-Egger, and mode-based estimates, to compute the odds ratios (ORs) that articulate the impact of these markers on gastric cancer susceptibility. The IVW method revealed that the interleukin 6 receptor was inversely correlated with gastric cancer progression (OR = 0.86, 95% CI = 0.74-0.99, P = .03), whereas fatty acid-binding protein 4 was found to elevate the risk (OR = 1.21, 95% CI = 1.05-1.39, P = .03). Instrumental variables comprised 5, 4, 7, 2, and 3 SNPs respectively. Convergent findings from WME, MR-Egger, and mode-based analyses corroborated these associations. Sensitivity checks, including heterogeneity, horizontal pleiotropy assessments, and leave-one-out diagnostics, affirmed the robustness and reliability of our instruments across diverse gastric malignancy tissues without substantial bias. Our research suggests that the interleukin 6 receptor potentially mitigates, while fatty acid-binding protein 4 may contribute to the pathogenesis of gastric cancer (GC). Unraveling the intricate biological interplay between inflammation and oncogenesis offers valuable insights for preemptive strategies and therapeutic interventions in gastric malignancy management.

Bayesian diagnostic test evaluation and true prevalence estimation of malnutrition in gastric cancer patients

BACKGROUND & AIMS

Malnutrition is prevalent among gastric cancer (GC) patients, necessitating early assessment of nutritional status to guide monitoring and interventions for improved outcomes. We aim to evaluate the accuracy and prognostic capability of three nutritional tools in GC patients, providing insights for clinical implementation.

METHODS

The present study is an analysis of data from 1308 adult GC patients recruited in a multicenter from July 2013 to July 2018. Nutritional status was assessed using Nutritional Risk Screening 2002 (NRS-2002), Patient-Generated Subjective Global Assessment (PG-SGA) and Global Leadership Initiative on Malnutrition (GLIM) criteria. Bayesian latent class model (LCM) estimated the malnutrition prevalence of GC patients, sensitivity and specificity of nutritional tools. Cox regression model analyzed the relationship between nutritional status and overall survival (OS) in GC patients.

RESULTS

Among 1308 GC patients, NRS-2002, PG-SGA, and GLIM identified 50.46%, 76.76%, and 68.81% as positive, respectively. Bayesian LCM analysis revealed that PG-SGA had the highest sensitivity (0.96) for malnutrition assessment, followed by GLIM criteria (0.78) and NRS-2002 (0.65). Malnutrition or being at risk of malnutrition were identified as independent prognostic factors for OS. Use any of these tools improved survival prediction in TNM staging system.

CONCLUSION

PG-SGA is the most reliable tool for diagnosing malnutrition in GC patients, whereas NRS-2002 is suitable for nutritional screening in busy clinical practice. Given the lower sensitivity of NRS-2002, direct utilization of GLIM for nutritional assessment may be necessary. Each nutritional tool should be associated with a specific course of action, although further research is needed.

Adherence to Oral Nutrition Supplementation in Gastrointestinal Cancer Patients: A Systematic Review of the Literature

The prevalence of malnutrition is high in gastrointestinal (GI) cancer patients. The use of oral nutrition supplementation (ONS) as part of patients' nutritional therapy seems to be effective in the improvement of nutritional status. Nevertheless, oncology patients, experience several symptoms that negatively affect their compliance with ONS products. Τhe aim of this systematic review is to examine the factors affecting compliance with ONS in patients who underwent GI cancer surgery and/or adjuvant treatments. A systematic search was conducted to identify studies published until June 2023 that assessed compliance to ONS in GI cancer patients. Eleven studies fulfilled the eligibility criteria and were included in the analysis. Postoperative compliance with ONS among GI cancer surgery patients ranged between 26.2% and 71.1%, whereas in GI cancer patients receiving chemotherapy the average reported rate was 90.2%. The main reasons for noncompliance were the presence of GI symptoms, such as early satiety, bloating, and diarrhea after ONS consumption, as well as taste alterations that result in aversion to the provided ONS. Frequent monitoring of these patients is crucial in order to record adverse effects, identify patients that are in need of personalized guidance at an early stage and motivate them to follow their ONS plan.
