Association between cachexia, chemotherapy and outcomes in older cancer patients: A systematic review

Clinical significance of cachexia index determined by bioelectrical impedance analysis in patients with gastrointestinal cancer

Cancer cachexia is a complex disorder characterized by skeletal muscle loss, which may influence the prognosis of patients with cancer. The cachexia index (CXI) is a new index for cachexia. The present study aimed to assess whether the CXI determined by bioelectrical impedance analysis (BIA) is valuable for predicting survival in patients with gastrointestinal cancer. A total of 54 patients with gastrointestinal cancer undergoing BIA at the time of diagnosis at Fukuchiyama City Hospital (Kyoto, Japan) were retrospectively recruited. CXI values were calculated as follows: CXI=skeletal muscle index (SMI) × serum albumin concentration/neutrophil-to-lymphocyte ratio. The SMI was measured using BIA values. The patients were classified into low- and high-CXI groups. The median patient age was 72 years and 63.0% of patients were male. A total of 20 patients with colorectal cancer were enrolled, 12 with pancreatic cancer, 11 with gastric cancer, 6 with esophageal cancer, 4 with biliary tract cancer and 1 with liver cancer. The cumulative one-year overall survival (OS) rate was significantly worse in the low-CXI group compared with that in the high-CXI group (58.3 vs. 88.5%; P=0.012). By contrast, the SMI had no significant effect on OS. Thus, CXI values using BIA may predict survival in patients with gastrointestinal cancer.

Malnutrition Diagnosed by Patient-Generated Subjective Global Assessment and the Risk of All-Cause Mortality in Adults With Gastrointestinal Cancer: A Systematic Review and Meta-Analysis

INTRODUCTION

Several reviews have highlighted that the Patient-Generated Subjective Global Assessment (PG-SGA) is the best diagnostic tool for assessing nutritional status in cancer patients. However, previous meta-analyses summarizing the prevalence of malnutrition and overall survival in patients with gastrointestinal (GI) cancer are quite limited. This study aims to determine the overall prevalence and association between malnutrition, as defined by the PG-SGA, and mortality in adults with GI cancer.

METHODS

A comprehensive systematic review of articles published from 2005 to 2023 was conducted using Google Scholar, PubMed, Web of Sciences and Scopus. The PRISMA guideline was followed to organize the entire content. A random-effects meta-analysis model using R Studio was performed to quantify the pooled proportion and hazard ratios (HRs). Publication bias was assessed using Egger's test and funnel plots. Heterogeneity was evaluated using I2 and Baujat plots. This study was registered in PROSPERO under the protocol number CRD42023465685.

RESULTS

In this study, 46 publications with 23,235 participants were included in the final meta-analysis. The overall prevalence of malnutrition among adults with GI cancer, as determined by the PG-SGA, was 61% (95% CI: 51%-70%, I2 = 99%). The pooled prevalence of moderate and severe malnutrition were 38% (95% CI: 31%-45%, I2 = 96%) and 21% (95% CI: 13%-31%, I2 = 98%), respectively. By cancer type, malnutrition was more common in patients with oesophageal cancer (78%, 95% CI: 45%-94%, I2 = 99%) and gastric cancer (75%, 95% CI: 68%-81%, I2 = 87%). Additionally, the overall risk (pooled HR) of malnutrition on mortality among GI cancer patients was 2.02 (95% CI: 1.63%-2.5%, I2 = 23%).

CONCLUSION

Malnutrition is common in adults with GI cancer and doubles the risk of all-cause mortality. These results emphasize the importance of ongoing efforts in prevention, early assessment, and intervention for malnutrition to minimize mortality rates.

Malnutrition risk and overall survival at solid tumour diagnosis

PURPOSE

Malnutrition severely impacts tolerance to anticancer therapies, but any relationship with overall survival (OS) at the time of solid tumour diagnosis in outpatients in the USA remains unclear.

METHODS

This retrospective study evaluated 3562 patients who completed the Malnutrition Screening Tool (MST) at diagnosis, identifying the relationship between MST risk, a validated tool evaluating anorexia and weight loss, and OS. MST score of ≥2 of 5 was classified as high malnutrition risk (H-MST). Kaplan-Meier techniques and Cox proportional hazards models were used to analyse OS in H-MST versus low malnutrition risk (L-MST).

RESULTS

In the unadjusted models, MST risk was individually associated with OS. Multivariable regression confirmed that MST risk remained independently prognostic for OS after controlling for key confounding variables, HR=1.51 (95% CI: 1.33 to 1.72). The H-MST group had shorter OS (50-month survival rates: 69% L-MST vs 60% H-MST).

CONCLUSION

MST risk at diagnosis is an independent prognostic factor for OS. H-MST risk is associated with shorter survival in a broad cohort of solid tumour oncology outpatients.

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.

ACVR2B polymorphism, Adiponectin, and GDF-15 levels as biomarkers for cachexia in gastrointestinal cancer

Reversing cancer cachexia remains a challenge. Genetic biomarkers for the early detection of the disease have been explored in order to enable the implementation of preventive measures. We therefore genotyped candidate genes based on cachexia phenotype and quantified adiponectin and GDF-15 levels in cachectic patients with gastrointestinal cancer. Patients with a diagnosis of gastrointestinal cancer were divided into a cachectic and a non-cachectic group after the start of chemotherapy. A control group (no cancer) was also included. We genotyped the following single nucleotide polymorphisms (SNPs) by quantitative PCR: FOXO3 (rs1935949), FOXO3 (rs4946935), ACVR2B (rs2268757), and SELP (rs6136). In addition, we quantified adiponectin and GDF-15 levels by ELISA. The rs2268757 SNP in the ACVR2B gene was associated with the weight loss phenotype in cachectic patients with gastrointestinal cancer (non-cachectic, P = 0.004). Plasma adiponectin levels were higher in cachectic patients compared to controls (P = 0.01) and non-cachectic patients (P = 0.004). GDF-15 was also elevated in cachectic patients compared to controls (P < 0.0001) and non-cachectic patients (P = 0.001). Analysis by sex showed elevated adiponectin levels in men (control, P = 0.01) and cachectic women (control, P = 0.04; non-cachectic, P = 0.01), as well as elevated GDF-15 levels in men (control, P = 0.002) and cachectic women (control, P = 0.002; non-cachectic, P = 0.007). However, there was no significant difference in the levels of these cytokines between cachectic men and women. The results suggest the rs2268757 SNP in the ACVR2B gene, adiponectin, and GDF-15 as potential biomarkers of cachexia in gastrointestinal cancer.

Weight loss, nutritional aspects and quality of life in head and neck cancer survivors

OBJECTIVES

Comprehensive care is fundamental to cancer survivors enduring long-term side-effects of cancer treatment including nutrition impact symptoms and critical weight loss (CWL). The aim of our study was to address weight loss (WL), nutritional aspects, and quality of life (QoL) in head and neck cancer (HNC) survivors.

STUDY DESIGN

This was a cross-sectional study of HNC patients treated at the Sapienza University-Hospital, 2018-2022. We administered a modified version of the EORTC-QLQ-H&N35, the National Health and Nutrition Examination Survey for taste disorders, and the Fox Questionnaire for dry mouth. WL was recorded at T0 (before cancer treatment), T1 (right after treatment), and (at follow-up) T2.

RESULTS

All patients (n = 63; 61.9% males) had a median WL of 16.7% (range: 1.4%-44.2%) at T1 and a median of 9.8% (range: 1.8%-45.6%) at T2. Patients with dysgeusia, poor dentition, and those who underwent major orofacial surgery had the highest WL (P < .05). Patients who received multiple treatment regimens had a higher WL compared to those receiving fewer regimens (P < .05). Patients with nutritional problems (71.4%) had a lower QoL throughout (P < .05).

CONCLUSIONS

CWL is an important side effect of HNC treatment and may particularly affect survivors with xerostomia/dysgeusia, poor dentition, and those receiving multiple treatment regimens.

Serious Health-Related Suffering Impairs Treatments and Survival in Older Patients With Cancer

CONTEXT

More than half of new cancer cases occurred in older adults. Older patients with cancer are particularly at risk of physical, psycho-existential or socio-familial suffering as defined by the concept of Serious Health-related Suffering (SHS).

OBJECTIVES

To assess the direct and indirect effects of physical, psycho-existential and socio-familial dimensions of suffering on cancer treatability, supportive care needs and 12-month mortality in older patients with cancer.

METHODS

We included patients with cancer aged 70 years and over from the Elderly Cancer Patients cohort (ELCAPA, Ile-de-France), referred for geriatric assessment between 2007 and 2019 before cancer treatment. Structural equation modelling examined the direct and indirect relationships between SHS dimensions (latent variables), patients' characteristics (age, sex, tumor location and metastatic status, comorbidity, period of care), and outcomes.

RESULTS

The analysis included 4,824 patients (mean age: 82.2 ± 4 years; women: 56%; main cancer sites: breast [22.3%], colorectal [15.2%], prostate [8.5%], and lung [6.8%]; metastatic cancer: 46%). Physical suffering had direct pejorative effects on cancer treatability, and mortality (standardized coefficient [SC] = 0.12 [P < 0.001], SC = 0.27 [P < 0.001], respectively). Psycho-existential and socio-familial sufferings had indirect pejorative effects on survival through decreased cancer treatability (SC = 0.08 [P < 0.001], SC = 0.03 [P < 0.001], respectively). Psycho-existential dimension had the main direct effect size on supportive care needs (SC = 0.35 [P < 0.001]) and was interrelated with physical suffering.

CONCLUSION

Physical suffering has direct pejorative effect on survival. All dimensions indirectly decrease survival due to poorer cancer treatability. Our findings support concomitant management of physical and psycho-existential suffering.

Impact of preoperative haemoglobin, albumin, lymphocyte, and platelet score on oral cancer prognosis

OBJECTIVE

To evaluate the preoperative haemoglobin, albumin, lymphocyte, and platelet score as a prognostic indicator in oral squamous cell carcinoma treated by radical surgery.

SUBJECTS AND METHODS

Patients (83 men, 32 women; 65.80 ± 11.47 years) who underwent radical surgery between 2012 and 2022 were included. Factors affecting overall survival and disease-free survival according to the haemoglobin, albumin, lymphocyte, and platelet score were examined. Patients were categorised into low- and high-score groups using optimal cut-off values obtained from receiver operating characteristic curve analysis.

RESULTS

The low-score group had poorer overall and disease-free survival (p < 0.001 each). Multivariate analysis identified alcohol consumption (hazard ratio [HR], 3.83; 95% confidence interval [CI]: 1.56-9.41, p = 0.003); vascular invasion (HR, 3.97; 95% CI: 1.60-9.85, p = 0.003); and the haemoglobin, albumin, lymphocyte, and platelet score (HR, 0.39; 95% CI: 0.20-0.78, p = 0.007) as independent prognostic factors for overall survival and vascular (HR, 3.66; 95% CI: 1.79-7.50, p < 0.001) and lymphovascular (HR, 2.44; 95% CI: 1.36-4.41, p = 0.003) invasion as independent prognostic factors for disease-free survival.

CONCLUSION

The preoperative haemoglobin, albumin, lymphocyte, and platelet score may be a significant prognostic factor for patients with oral squamous cell carcinoma undergoing radical surgery.

Mechanisms of cancer cachexia and targeted therapeutic strategies

Tumor cachexia is a multifactorial syndrome characterized by systemic dysfunction, including anorexia and severe weight loss that is resistant to standard nutritional interventions. It is estimated that approximately 20 % of cancer patients succumb to cachexia in the later stages of their disease. Thus, understanding its pathogenesis is vital for improving therapeutic outcomes. Recent research has focused on the imbalance between energy intake and expenditure in cachexia. Clinically, cachexia presents with anorexia, adipose tissue atrophy, and skeletal muscle wasting, each driven by distinct mechanisms. Anorexia arises primarily from tumor-secreted factors and cancer-induced hormonal disruptions that impair hypothalamic regulation of appetite. Adipose tissue atrophy is largely attributed to enhanced lipolysis, driven by increased activity of enzymes such as adipose triglyceride lipase and hormone-sensitive lipase, coupled with decreased lipoprotein lipase activity. The browning of white adipose tissue, facilitated by uncoupling protein 1, further accelerates fat breakdown by increasing energy expenditure. Skeletal muscle atrophy, a hallmark of cachexia, results from dysregulated protein turnover via the ubiquitin-proteasome and autophagy-lysosomal pathways, as well as mitochondrial dysfunction. Additionally, chemotherapy can exacerbate cachexia. This review examines the molecular mechanisms underlying cancer cachexia and discusses current therapeutic strategies, aiming to inform future research and improve treatment approaches.

The toxicological analysis of problematic and sophisticated elements (Ni, Cr, and Se) in Food for Special Medical Purposes (FSMP) using in pharmacotherapy and clinical nutrition for oncological patients available in Polish pharmacies

This study focuses on FSMPs for oncologic patients, specifically analyzing the toxicological profiles of nickel (Ni), chromium (Cr), and selenium (Se) within these products available in Polish pharmacies. The presence of these elements was quantified using inductively coupled plasma mass spectrometry (ICP-MS). Results indicated variations in the concentrations of Ni, Cr, and Se across different FSMP samples, with some products exceeding the acceptable limits set by regulatory guidelines. The study highlights the potential health risks associated with nickel exposure, including dermatitis and carcinogenesis, and the complex roles of chromium and selenium, which can be both beneficial and harmful depending on their levels. Our findings reveal significant variability in the elemental content across different FSMP products, i.e.: Ni: 0.155-25.488 μg/portion, Cr: 0.076-28.726 μg/portion and Se: 0.083-20.304 μg/portion). Notably, selenium levels in FSMPs showed considerable discrepancies compared to manufacturers' declarations, averaging only about 20% of the stated values. Regulatory assessments based on the Acceptable Daily Intake (ADI) and Permitted Daily Exposure (PDE) descriptors indicated that the estimated weekly intake of Ni, Cr, and Se from these FSMPs did not exceed the provisional tolerable weekly intake (PTWI) values. However, the highest Ni content was 30.58% of the PTWI, raising concerns about potential health risks, including dermatitis and carcinogenesis. The results for Cr underscored the necessity for careful monitoring due to its potential toxic effects. Selenium, despite its essential role, showed levels inadequate to meet the Recommended Dietary Allowance (RDA), potentially impacting its intended health benefits.

Systematic nutritional screening and assessment in older patients: Rationale for its integration into oncology practice

As the global population ages, so does the number of older people being diagnosed, treated and surviving cancer. Challenges to providing appropriate healthcare management stem from the heterogeneity common in this population. Although malnutrition is highly prevalent in older people with cancer, ranging between 30 % and 80 % according to some analyses, is associated with frailty, and has been shown to be a major risk factor for poor treatment response and worse overall survival, addressing nutrition status is not always a priority among oncology healthcare providers. Evaluation of nutritional status is a two-step process: screening identifies risk factors for reduced nutritional intake and deficits that require more in-depth assessment. Screening activities can be as simple as taking weight and BMI measurements or using short nutritional questionnaires and asking the patient about unintentional weight loss to identify potential nutritional risk. Using geriatric assessment, deficits in the nutritional domain as well as in others reveal potentially reversible geriatric and medical problems to guide specific therapeutic interventions. The authors of this paper are experts in the fields of geriatric medicine, oncology, and nutrition science and believe that there is not only substantial evidence to support regularly performing screening and assessment of nutritional status in older patients with cancer, but that these measures lead to the planning and implementation of patient-centered approaches to nutrition management and thus enhanced geriatric-oncology care. This paper presents rationale for systematic nutrition screening and assessment in older adults with cancer.

Salivary Interleukin-13 and Transforming Growth Factor Beta as Potential Biomarkers of Cancer Cachexia

Cancer cachexia is a syndrome characterized by weight and muscle loss and functional impairment, strongly influencing survival in cancer patients. In this study, we aimed to establish the role of saliva cytokine measurement in cancer cachexia investigation and define two potential independent salivary biomarkers of the condition.

METHODS

serum and saliva specimens were obtained from 78 patients. Forty-six patients were non-cachectic, and 32 patients were cachectic (per SCRINIO group criteria), all with metastatic solid tumors. Commercial ELISA kits were used to determine the salivary and serum concentrations of interleukin 13 (IL-13) and transforming growth factor beta (TGF-β) in two patient groups and healthy controls. Laboratory values were obtained from the hospital information system, and weight and height were measured at the time of sampling.

RESULTS

A statistically significant difference was observed between the groups in saliva IL-13 concentrations but no difference in serum concentrations. Statistically significant differences were also observed between the groups in saliva and serum concentrations of TGF-β. Logistic regression analysis has identified salivary IL-13 and TGF-β as independent factors for cancer cachexia.

CONCLUSIONS

We demonstrated saliva as a valuable specimen for cachexia investigation and established IL-13 and TGF-β as potential cancer cachexia biomarkers. Further research is needed to evaluate these findings.

Impact of the Combination of Anamorelin and Rehabilitation on Functional and Nutritional Outcomes in Patients with Cancer Cachexia

Cancer cachexia, characterized by the progressive loss of skeletal muscle mass, leads to functional impairment and poor prognosis. Anamorelin is approved for treating cancer cachexia in Japan; however, the factors influencing its discontinuation and the impact of combining anamorelin with rehabilitation remain unclear. Therefore, we retrospectively analyzed 82 patients with cancer cachexia to identify factors associated with anamorelin discontinuation and assess changes in nutritional status and motor function using non-dominant handgrip strength after 12 wk. Patients received outpatient rehabilitation, combining resistance and aerobic training every two weeks, alongside anamorelin therapy. Our findings indicate that patients with an ECOG performance status of 1 or 2 were less likely to continue anamorelin therapy for 12 wk compared to those with a performance status of 0 (odds ratio 2.71; 95% CI 1.05 - 7.00; p = 0.040). Significant improvements were observed in body weight (48.8 to 53.7 kg, p < 0.001), skeletal muscle mass (6.4 to 6.9 kg/m2, p < 0.001), FAACT score (11.5 to 18.0, p < 0.001), and non-dominant handgrip strength (20.5 to 21.7 kg, p = 0.018) after 12 wk. Early initiation of anamorelin with regular rehabilitation is recommended to enhance nutritional status and motor function in patients with cancer cachexia.

Family Members' Explanatory Models of Cancer Anorexia-Cachexia

The experience of bearing witness to the lack of appetite and involuntary weight loss that characterizes cancer anorexia-cachexia syndrome (CACS) is reported to be stressful for family members. Research identifies that family members engage in a wide range of behaviors in response to a relative who shows minimal interest in eating and is literally 'wasting away' before their eyes. Some families, though concerned about the symptoms of CACS, do not dwell excessively on the patient's nutritional intake while others continually harass the patient to eat and petition health care providers for aggressive nutritional interventions to eat in an attempt to stave off further physical deterioration. While studies have detailed how family members respond to a terminally ill relative with CACS, empirical work explicating the explanatory models of CACS that they hold is lacking. Explanatory models (EMs) reflect the beliefs and ideas that families have about why illness and symptoms occur, the extent to which they can be controlled, how they should be treated, and how interventions should be evaluated. To address this gap in the literature, a grounded theory study guided by Kleinman's Explanatory Model questions was conducted with 25 family members of advanced cancer patients. The core category of 'Wayfaring' integrates the key categories of the model and maps onto Kleinman's questions about CACS onset, etiology, natural course, physiological processes/anatomical structures involved, treatment, and the impacts of disease on patient and family. Findings suggest that a divergence between some biomedical constructions of CACS and explanatory models held by family members may fuel the family-health care provider conflict, thereby providing direction for communication with families about care of the patient with anorexia-cachexia.

Effect of a multimodal intervention in breast Cancer patients undergoing neoadjuvant therapy: A study protocol of the multimodal project

BACKGROUND AND AIMS

To determine the effect of a multimodal intervention (nutritional behavior change and physical exercise) on quality of life, chemotherapy response rate and tolerance, histopathological level of the tumor, body composition, and biochemical parameters, in patients diagnosed with breast cancer during neoadjuvant chemotherapy treatment, and to compare them with the control group.

METHODS

Anticipated 80 patients diagnosed with breast cancer aged 18-70 years will be recruited for this randomized, unblinded clinical trial based on a nutritional behavior change and physical exercise in patients during the approximately 6 months in which the patient receives neoadjuvant treatment. Participants will be randomly allocated (1:1) to one of two groups (intervention or control). Primary and secondary outcomes will be assessed before the beginning and after the neoadjuvant treatment (before surgery). The primary outcome is quality of life, whereas secondary outcomes include chemotherapy response rate and tolerance, histopathological level of the tumor and body composition (i.e., visceral adipose tissue activity, bone, lean and fat masses). We will analyze blood parameters (i.e., biochemical, inflammatory, and tumor markers) as exploratory outcomes.

CONCLUSION

This study will address the influence of a practical and viable multimodal intervention (i.e., nutritional behavior change and physical exercise) on breast cancer patients undergoing neoadjuvant chemotherapy. Given the practical viability of the intervention in real-world settings, our study holds promise for significant scientific and clinical implications.

Malnutrition, sarcopenia and cachexia: exploring prevalence, overlap, and perceptions in older adults with cancer

BACKGROUND

Older adults with cancer are a growing population requiring tailored care to achieve optimum treatment outcomes. Their care is complicated by under-recognised and under-treated wasting disorders: malnutrition, sarcopenia, and cachexia. We aimed to investigate the prevalence, overlap, and patients' views and experiences of malnutrition, sarcopenia, and cachexia, in older adults with cancer.

METHODS

Mixed-methods study with cross-sectional study and qualitative interviews. Interviews were thematically analysed through a phenomenological lens, with feedback loop analysis investigating relationships between themes and findings synthesised using modified critical interpretative synthesis.

FINDINGS

n = 30 were screened for malnutrition, sarcopenia, and cachexia, n = 8 completed semi-structured interviews. Eighteen (60.0%) were malnourished, 16 (53.3%) sarcopenic, and 17 (56.7%) cachexic. One or more condition was seen in 80%, and all three in 30%. In univariate analysis, Rockwood clinical frailty score (OR 2.94 [95% CI: 1.26-6.89, p = 0.013]) was associated with sarcopenia, reported percentage meal consumption (OR 2.28 [95% CI: 1.24-4.19, p = 0.008]), and visible wasting (OR 8.43 [95% CI: 1.9-37.3] p = 0.005) with malnutrition, and percentage monthly weight loss (OR 8.71 [95% CI: 1.87-40.60] p = 0.006) with cachexia. Screening tools identified established conditions rather than 'risk'. Nutritional and functional problems were often overlooked, overshadowed, and misunderstood by both patients and (in patients' perceptions) by clinicians; misattributed to ageing, cancer, or comorbidities. Patients viewed these conditions as both personal impossibilities, yet accepted inevitabilities.

CONCLUSION

Perceptions, identification, and management of these conditions needs to improve, and their importance recognised by clinicians and patients so those truly 'at risk' are identified whilst conditions are more remediable to interventions.

Identification of cachexia in lung cancer patients with an ensemble learning approach

Objective

Nutritional intervention prior to the occurrence of cachexia will significantly improve the survival rate of lung cancer patients. This study aimed to establish an ensemble learning model based on anthropometry and blood indicators without information on body weight loss to identify the risk factors of cachexia for early administration of nutritional support and for preventing the occurrence of cachexia in lung cancer patients.

Methods

This multicenter study included 4,712 lung cancer patients. The least absolute shrinkage and selection operator (LASSO) method was used to obtain the key indexes. The characteristics excluded weight loss information, and the study data were randomly divided into a training set (70%) and a test set (30%). The training set was used to select the optimal model among 18 models and verify the model performance. A total of 18 machine learning models were evaluated to predict the occurrence of cachexia, and their performance was determined using area under the curve (AUC), accuracy, precision, recall, F1 score, and Matthews correlation coefficient (MCC).

Results

Among 4,712 patients, 1,392 (29.5%) patients were diagnosed with cachexia based on the framework of Fearon et al. A 17-variable gradient boosting classifier (GBC) model including body mass index (BMI), feeding situation, tumor stage, neutrophil-to-lymphocyte ratio (NLR), and some gastrointestinal symptoms was selected among the 18 machine learning models. The GBC model showed good performance in predicting cachexia in the training set (AUC = 0.854, accuracy = 0.819, precision = 0.771, recall = 0.574, F1 score = 0.658, MCC = 0.549, and kappa = 0.538). The abovementioned indicator values were also confirmed in the test set (AUC = 0.859, accuracy = 0.818, precision = 0.801, recall = 0.550, F1 score = 0.652, and MCC = 0.552, and kappa = 0.535). The learning curve, decision boundary, precision recall (PR) curve, the receiver operating curve (ROC), the classification report, and the confusion matrix in the test sets demonstrated good performance. The feature importance diagram showed the contribution of each feature to the model.

Conclusions

The GBC model established in this study could facilitate the identification of cancer cachexia in lung cancer patients without weight loss information, which would guide early implementation of nutritional interventions to decrease the occurrence of cachexia and improve the overall survival (OS).

Bioelectrical impedance analysis-derived phase angle (PhA) in lung cancer patients: a systematic review

BACKGROUND

Lung cancer is the second most diagnosed cancer in the world. Up to 84% of diagnosed patients have malnutrition, which can negatively affect quality of life and survival and may worsen with neoadjuvant treatment. Bioelectrical Impedance Analysis-Derived Phase Angle (PhA) in these patients could be a valid tool to assess the nutritional status in order to improve their condition.

METHODS

This review provides an update on PhA assessment in lung cancer patients over the past twenty years. We searched PubMed, Embase, Scopus, Web of Science, and Cochrane, for articles regarding the PhA obtained from Bioelectrical Impedance Analysis in lung cancer patients. The authors independently performed a literature search: sample size, patient population, study type, study dates, survival and interventions were evaluated. The final review included 11 studies from different countries.

RESULTS

Eight studies only considered patients with lung cancer, while three studies considered patients with different kind of cancer, including lung. Correlation data between PhA and age are conflicting. In patients undergoing clinical treatment and patients undergoing surgical treatment lower PhA was observed. A lower PhA is associated with a shorter survival. In three studies emerged a relationship between Karnofski Performance Status and Handgrip Strenght with PhA. From one study, univariate logistic regression analysis showed that higher PhA values represent a protective factor for sarcopenia.

CONCLUSION

Our research underlined interesting, but not conclusive, results on this topic; however more researches are needed to understand the clinical meaning of PhA.

Influence of malnutrition according to the glim criteria on the chemotherapy toxicities in patients with advanced lung cancer

BACKGROUND

Cancer-associated malnutrition is highly prevalent in advanced lung cancer, and 50% of global cancer-related deaths are attributed to cancer-associated malnutrition. Platinum-containing chemotherapy is the standard treatment for advanced lung cancer. Unfortunately, it can cause exacerbated toxicities, which can also have a negative impact on patient's prognosis and quality of life. The Global Leadership Initiative on Malnutrition (GLIM) criteria have been proposed as the world's first accepted diagnostic criteria for malnutrition. However, the effectiveness of GLIM criteria in predicting chemotherapy toxicities in patients with advanced lung cancer is unclear. The aim of this study was to apply the GLIM criteria to assess the prevalence of pre-treatment diagnosis of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) and to determine the impact of nutritional status on patient's chemotherapy toxicity.

METHODS

We conducted a study of hospitalized patients with pathologically and clinically diagnosed advanced NSCLC who presented to our hospital from May 2021 to January 2022. Initially, the Nutritional Risk Screening-2002 (NRS-2002) was used for nutritional risk screening, and nutritional status was assessed using the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and GLIM criteria. Chemotherapy toxicity was assessed and graded according to CTCAE5.0, and chemotherapy efficacy was assessed according to RECIST1.1. Kappa test was used to analyze the agreement between PG-SGA and GLIM criteria. Univariate and multivariate logistic regression analyses were used to determine the relationship between malnutrition and chemotherapy toxicity.

RESULTS

A total of 215 patients with advanced NSCLC were evaluated for nutritional status. Most of the patients had normal BMI (61.86%) before the start of treatment, 40% were well-nourished as assessed by the PG-SGA tool, and 51.17% were well-nourished as assessed by GLIM criteria. Consistency analysis showed moderate agreement (Kappa = 0.463, P < 0.001) and their correlation was also moderate (Spearman, rs = 0.475, P < 0.001). The objective response rate (ORR) (P = 0.040) and disease control rate (DCR) (P < 0.001) were significantly lower in malnourished patients diagnosed according to GLIM criteria than in well-nourished patients. Multivariate analysis showed that malnutrition (OR = 1.531,95%CI 0.757-3.009; OR = 6.623,95%CI 1.390-31.567, P = 0.046) diagnosed by GLIM criteria was an independent predictor of chemotherapy toxicity. Conclusions Malnutrition diagnosed by GLIM criteria better predicts toxicity during chemotherapy, determines the degree of clinical benefit of chemotherapy, and may affect patient prognosis.

Transcutaneous carbon dioxide suppresses skeletal muscle atrophy in a mouse model of oral squamous cell carcinoma

Cancer cachexia causes skeletal muscle atrophy, impacting the treatment and prognosis of patients with advanced cancer, but no treatment has yet been established to control cancer cachexia. We demonstrated that transcutaneous application of carbon dioxide (CO2) could improve local blood flow and reduce skeletal muscle atrophy in a fracture model. However, the effects of transcutaneous application of CO2 in cancer-bearing conditions are not yet known. In this study, we calculated fat-free body mass (FFM), defined as the skeletal muscle mass, and evaluated the expression of muscle atrophy markers and uncoupling protein markers as well as the cross-sectional area (CSA) to investigate whether transcutaneous application of CO2 to skeletal muscle could suppress skeletal muscle atrophy in cancer-bearing mice. Human oral squamous cell carcinoma was transplanted subcutaneously into the upper dorsal region of nude mice, and 1 week later, CO2 gas was applied to the legs twice a week for 4 weeks and FFM was calculated by bioimpedance spectroscopy. After the experiment concluded, the quadriceps were extracted, and muscle atrophy markers (muscle atrophy F-box protein (MAFbx), muscle RING-finger protein 1 (MuRF-1)) and uncoupling protein markers (uncoupling protein 2 (UCP2) and uncoupling protein 3 (UCP3)) were evaluated by real-time polymerase chain reaction and immunohistochemical staining, and CSA by hematoxylin and eosin staining. The CO2-treated group exhibited significant mRNA and protein expression inhibition of the four markers. Furthermore, immunohistochemical staining showed decreased MAFbx, MuRF-1, UCP2, and UCP3 in the CO2-treated group. In fact, the CSA in hematoxylin and eosin staining and the FFM revealed significant suppression of skeletal muscle atrophy in the CO2-treated group. We suggest that transcutaneous application of CO2 to skeletal muscle suppresses skeletal muscle atrophy in a mouse model of oral squamous cell carcinoma.

Comparison of the prognostic value of eight nutrition-related tools in older patients with cancer: A prospective study

OBJECTIVES

The primary objective of the present study was to evaluate and compare the ability of eight nutrition-related tools to predict 1-year mortality in older patients with cancer.

DESIGN, SETTING AND PARTICIPANTS

We studied older patients with cancer from the ELCAPA cohort and who had been referred for a geriatric assessment at one of 14 participating geriatric oncology clinics in the greater Paris area of France between 2007 and 2018.

MEASUREMENTS

The studied nutrition-related tools/markers were the body mass index (BMI), weight loss (WL) in the previous 6 months, the Mini Nutritional Assessment, the Geriatric Nutritional Risk Index (GNRI), the Prognostic Nutritional Index, the Glasgow Prognostic Score (GPS), the modified GPS, and the C-reactive protein/albumin ratio.

RESULTS

A total of 1361 patients (median age: 81; males: 51%; metastatic cancer: 49%) were included in the analysis. Most of the tools showed a progressively increase in the mortality risk as the nutrition-related risk category worsened (overall p-values <0.02 for all) after adjustment for age, outpatient status, functional status, severe comorbidities, cognition, mood, cancer treatment strategy, tumour site, and tumour metastasis. All the models were discriminant, with a C-index ranging from 0.748 (for the BMI) to 0.762 (for the GPS). The concordance probability estimate ranged from 0.764 (WL) to 0.773 (GNRI and GPS)).

CONCLUSION

After adjustment for relevant prognostic factors, all eight nutrition-related tools/markers were independently associated with 1-year mortality in older patients with cancer. Depending on the time or context of the GA, physicians do not always have the time or means to perform and assess all the tools/markers compared here. However, even when some information is missing, each nutritional tool/marker has prognostic value and can be used in the evaluation.

High Sarcopenia Awareness Contrasts a Lack of Clinical Implementation Among Geriatric Rehabilitation Health Care Professionals in the Netherlands: EMPOWER-GR

BACKGROUND AND PURPOSE

Despite being associated with serious adverse outcomes, such as mortality, sarcopenia remains largely undiagnosed in older individuals. This study aimed to assess the awareness, practices, and barriers and enablers to clinical implementation of sarcopenia diagnosis and treatment among geriatric rehabilitation health care professionals in the Netherlands.

METHODS

As part of EMPOWER-GR, a cross-sectional survey among geriatric rehabilitation health care professionals working in the Netherlands was undertaken between September 23, 2020, and January 28, 2021. Professionals were recruited via a geriatric rehabilitation care provider, health care professional associations, professional networks of the research team, and social media. Descriptive statistics were used to assess the study outcomes.

RESULTS AND DISCUSSION

Of the 501 geriatric rehabilitation health care professionals, 12.2% were physicians, 23.0% physical therapist/occupational therapists, 30.3% dietitians, 19.6% nurses, and 11.0% health care assistants. The concept of sarcopenia was known by 83.8% of the participants, 92.5% correctly identified sarcopenia as low muscle mass and strength (and low physical performance), and 73.8% identified sarcopenia as very important in the management of older adults admitted for rehabilitation. Although 26.2% and 18.9% of the participants reported screening and diagnosing sarcopenia, respectively, in their current practice, only 3.0% adequately used the (revised) definition of the European Working Group on Sarcopenia in Older People. When sarcopenia has been diagnosed, 65.0% reported initiating treatment consisting of resistance exercise training (78.7%), food fortification/high-energy or protein diet (85.4%), and oral nutritional supplements (70.4%). Most important barriers to screening and diagnosis were lack of knowledge, access to tools, and equipment and time, while enablers were protocol implementation, access to training, and clear responsibilities.

CONCLUSIONS

Sarcopenia awareness is high among geriatric rehabilitation health care professionals in the Netherlands, but adequate screening and diagnosis is almost nonexistent in current clinical practice, which hampers interventions. Better knowledge, clear responsibilities, and access to tools and protocols, as well as prioritization, are needed for sarcopenia to be diagnosed and treated in geriatric rehabilitation in the Netherlands.

Characterisation and Outcomes of Patients with Solid Organ Malignancies Admitted to the Intensive Care Unit: Mortality and Impact on Functional Status and Oncological Treatment

BACKGROUND

Despite the increasing number of ICU admissions among patients with solid tumours, there is a lack of tools with which to identify patients who may benefit from critical support. We aim to characterize the clinical profile and outcomes of patients with solid malignancies admitted to the ICU.

METHODS

Retrospective observational study of patients with cancer non-electively admitted to the ICU of the Hospital Clinic of Barcelona (Spain) between January 2019 and December 2019. Data regarding patient and neoplasm characteristics, ICU admission features and outcomes were collected from medical records.

RESULTS

97 ICU admissions of 84 patients were analysed. Lung cancer (22.6%) was the most frequent neoplasm. Most of the patients had metastatic disease (79.5%) and were receiving oncological treatment (75%). The main reason for ICU admission was respiratory failure (38%). Intra-ICU and in-hospital mortality rates were 9.4% and 24%, respectively. Mortality rates at 1, 3 and 6 months were 19.6%, 36.1% and 53.6%. Liver metastasis, gastrointestinal cancer, hypoalbuminemia, elevated basal C-reactive protein, ECOG-PS greater than 2 at ICU admission, admission from ward and an APACHE II score over 14 were related to higher mortality. Functional status was severely affected at discharge, and oncological treatment was definitively discontinued in 40% of the patients.

CONCLUSION

Medium-term mortality and functional deterioration of patients with solid cancers non-electively admitted to the ICU are high. Surrogate markers of cachexia, liver metastasis and poor ECOG-PS at ICU admission are risk factors for mortality.

Demographic, clinical and psychological predictors of malnutrition among people with liver cancer

PURPOSE

This study aimed to explore the nutritional status and examine the demographic, clinical, nutritional, and psychosocial characteristics associated with malnutrition among people with liver cancer.

METHODS

A descriptive cross-sectional design was used. Data were collected from a convenience sample of 162 liver cancer outpatients at a tertiary university hospital. Nutritional status was evaluated using the Patient-Generated Subjective Global Assessment (PG-SGA). Self-administered structured questionnaires were administered, and medical records were reviewed for demographic, clinical, nutritional, and psychosocial characteristics.

RESULTS

Based on PG-SGA scores, 27 patients (16.7%) were classified into the malnutrition group. The stages of liver cancer, chemotherapy, physical and psychological symptom distress, global distress index, levels of alpha-fetoprotein and protein induced by vitamin K absence or antagonists, body mass index, appetite, hemoglobin and albumin levels, and depression were statistically significantly associated with malnutrition. Logistic regression model revealed that physical symptom distress, liver cancer stage, depression, and body mass index influenced statistically significantly malnutrition.

CONCLUSIONS

In this study, clinical, nutritional, and psychosocial characteristics predicted malnutrition among people with liver cancer. Nurses should consider these characteristics when evaluating the nutritional status of people with liver cancer.

High-protein home parenteral nutrition in malnourished oncology patients: a systematic literature review

INTRODUCTION

Up to 83% of oncology patients are affected by cancer-related malnutrition, depending on tumour location and patient age. Parenteral nutrition can be used to manage malnutrition, but there is no clear consensus as to the optimal protein dosage. The objective of this systematic literature review (SLR) was to identify studies on malnourished oncology patients receiving home parenteral nutrition (HPN) where protein or amino acid delivery was reported in g/kg bodyweight/day, and to compare outcomes between patients receiving low (< 1 g/kg bodyweight/day), standard (1-1.5 g/kg/day), and high-protein doses (> 1.5 g/kg/day).

METHODS

Literature searches were performed on 5th October 2021 in Embase, MEDLINE, and five Cochrane Library and Centre for Reviews and Dissemination databases. Searches were complemented by hand-searching of conference proceedings, a clinical trial registry, and bibliographic reference lists of included studies and relevant SLRs/meta-analyses.

RESULTS

Nineteen publications were included; sixteen investigated standard protein, two reported low protein, and one included both, but none assessed high-protein doses. Only one randomised controlled trial (RCT) was identified; all other studies were observational studies. The only study to compare two protein doses reported significantly greater weight gain in patients receiving 1.15 g/kg/day than those receiving 0.77 g/kg/day.

CONCLUSION

At present, there is insufficient evidence to determine the optimal protein dosage for malnourished oncology patients receiving HPN. Data from non-HPN studies and critically ill patients indicate that high-protein interventions are associated with increased overall survival and quality of life; further studies are needed to establish whether the same applies in malnourished oncology patients.

Association of the rs3917647 polymorphism of the SELP gene with malnutrition in gastric cancer

BACKGROUND

Malnutrition and cachexia are common syndromes in patients with gastric cancer (GC) and are associated with poor quality of life and poor disease prognosis. However, there is still a lack of molecular factors that can predict malnutrition or cachexia in cancer. Studies have shown that among the potential contributors to the development of cancer cachexia, the level of the inflammatory response to P-selectin is regulated by single nucleotide polymorphisms (SNPs) located in the promoter region of the SELP gene. The aim of this study was to evaluate the association between the single nucleotide polymorphism (SNP)-2028 A/G of the SELP gene and malnutrition in patients receiving chemotherapy for gastric cancer (GC).

METHODS

The study group consisted of 220 GC patients treated with chemotherapy at Jinhua Municipal Central Hospital. DNA was extracted from peripheral leukocytes of whole blood samples using an animal DNA extraction kit. DNA was amplified using a 1.1 × T3 Super PCR mix, and loci corresponding to the peaks were genotyped using SNP1 software.

RESULTS

Patients carrying the A allele had a reduced risk of developing malnutrition compared to patients with the GG genotype (P < 0.001; OR = 3.411; 95% CI = 1.785-6.516). In addition, multivariate analysis indicated that the AA genotype significantly (more than 16-fold) reduced the risk of developing malnutrition (P < 0.001; OR = 0.062; 95% CI = 0.015-0.255).

CONCLUSION

SELP -2028A/G SNP may be a useful marker for assessing the risk of malnutrition in GC patients.

Dynamic changes in physical function during intensive chemotherapy affect transplant outcomes in older adults with AML

Introduction

Intensive chemotherapy (IC) can affect all geriatric assessment (GA) domains in older adults with acute myeloid leukemia (AML), but data on the effects of these changes on transplant outcomes are lacking.

Methods

Therefore, we prospectively assessed the prognostic role of GA domains at diagnosis and allogeneic hematopoietic stem cell transplantation (allo-HSCT) in 51 patients with AML aged ≥60 years who achieved complete remission after IC. We performed both baseline and pre-allo-HSCT GA; moreover, physical function, including a short physical performance battery (SPPB), cognitive function, psychological function, nutritional status, and social support were examined.

Results

All GA domains showed dynamic changes between the two time points. The directions of change were statistically significant for social support, self-reported physical and psychological functions, and distress, but not for nutritional status, cognitive function, or physical function. Among all GA domains at each time point, only poor physical function and its submaneuvers at diagnosis but not at allo-HSCT were significantly associated with inferior survival. In particular, since the direction of change varied between patients, we found that patients whose physical function improved before allo-HSCT were more likely to survive longer than those with persistently impaired SPPB (55.6% vs. 28.6%, p=0.268). Finally, persistent impairment in SPPB (28.6% vs. 65.9%, p=0.006), tandem stand (0% vs. 63.3%, p=0.012), sit-and-stand (41.2% vs. 70.6%, p=0.009), and gait speed (38.5% vs. 68.4%, p=0.027) further strongly predicted inferior survival.

Discussion

This study showed that IC courses can induce dynamic changes in different directions in the GA domains of each patient and that changes in objectively measured physical function can predict transplant outcomes.

Curcumin as a hepatoprotective agent against chemotherapy-induced liver injury

Despite significant advances in cancer therapeutics, chemotherapy remains the cornerstone of treatment for many tumors. Importantly, however, chemotherapy-induced toxicity, including hepatotoxicity, can lead to the interruption or discontinuation of potentially effective therapy. In recent years, special attention has been paid to the search for complementary therapies to mitigate chemotherapy-induced toxicity. Although there is currently a lack of specific interventions to mitigate or prevent hepatotoxicity in chemotherapy-treated patients, the polyphenol compound curcumin has emerged as a potential strategy to overcome this adverse effect. Here we review, firstly, the molecular and physiological mechanisms and major risk factors of chemotherapy-induced hepatotoxicity. We then present an overview of how curcumin has the potential to mitigate hepatotoxicity by targeting specific molecular mechanisms. Hepatotoxicity is a well-described side effect of cytotoxic drugs that can limit their clinical application. Inflammation and oxidative stress are the most common mechanisms involved in hepatotoxicity. Several studies have shown that curcumin could prevent and/or palliate chemotherapy-induced liver injury, mainly due to its anti-inflammatory, antioxidant, antifibrotic and hypolipidemic properties. Further clinical investigation using bioavailable curcumin formulations is warranted to demonstrate its efficacy as an hepatoprotective agent in cancer patients.

Nutrition-associated health levels in persons with cancer: item response modelling based on the International Classification of Functioning, Disability and Health

BACKGROUND

The nutritional status of individuals with cancer is a crucial determinant of their health and well-being, and addressing nutrition-related functioning conditions is essential for maintaining physical activity levels and participating in daily activities.

AIM

This study aims to identify an evidence-based International Classification of Functioning, Disability and Health (ICF) scale using item response theory for nutrition conditions in patients with cancer, which can differentiate and assess nutrition-related functioning conditions of cancer survivors.

DESIGN

Cross-sectional study.

SETTING

Sir Run Run Hospital, Nanjing Medical University.

POPULATION

One hundred cancer patients were enrolled.

METHODS

Via convenience sampling, the study administered a questionnaire consisting of 89 ICF items to participants. The original five-point rating system was binarized (1 = no problem, 0 = problem). Through data shaping, non-parametric IRT analysis and parametric IRT analysis, psychometric properties of nutritional ICF scale were calculated using R software.

RESULTS

The study extracted a unidimensional scale with 32 items and constructed 2-parameter logistic model with good fitness, whose root mean square error approximation (RMSEA) = 0.0759, Tucker-Lewis Index (TLI) = 0.9655, and Comparative Fit Index (CFI) = 0.9677. The model demonstrated high reliability, as indicated by a Cronbach's α of 0.95, Guttman λ2 of 0.95, Molenaar Sijtsma statistic of 0.96 and a latent class reliability coefficient (LCRC) of 0.98. Besides, there was a strong correlation between the total score of 32 ICF items and the score of Patient-Generated Subjective Global Assessment (PG-SGA, P<0.001, r=-0.77) and Mini Nutritional Assessment (MNA, P<0.001, r=0.76), suggesting the 32-item scale had high validity.

CONCLUSIONS

The study constructed an evidence-based ICF scale for nutrition conditions in patients with cancer with 32-item and 2PLM for evaluating nutrition-associated health level in persons with cancer, including high validity and reliability.

CLINICAL REHABILITATION IMPACT

The IRT model based on ICF provided a promising assessment tool to discriminate nutrition-associated health level of persons with cancer, and offered an auxiliary method for selecting rehabilitation intervention targets. This has the potential to lead to improved outcomes in cancer treatment and increased quality of life for cancer survivors.

Bioimpedentiometry parameters used as indicators of frailty and malnutrition: association between G8 score and Phase angle (PHA) in elderly cancer patients

BACKGROUND

Since the incidence of cancer increases with age, in older cancer patients important information may be missed without a Comprehensive Geriatric Assessment (CGA). On the other side, CGA is a time-consuming and complex instrument, so that Geriatric 8 (G8) has been proposed as a more feasible screening tool to identify patients who could benefit from a CGA evaluation. G8 consists of 8 questions (patient age + 7 items derived from the Mini Nutritional Assessment questionnaire). A G8 score ≤ 14 is considered associated with frailty and risk of malnutrition. Another screening test is Bioelectrical Impedance Analysis (Bioimpedentiometry, BIA), which enables to evaluate the nutritional status through a specific parameter known as Phase angle (PhA). This study is aimed at assessing the ability of G8 alone or in combination with PhA to detect elderly cancer patients at higher risk for malnutrition who cannot undergo immediate anticancer treatments.

METHODS

A total of 289 cancer patients (168 men and 121 women) aged ≥ 70 years old were enrolled and performed both G8 test, body mass index (BMI) and BIA assessments. A concurrent G8 score ≤ 14 and PhA < 5 defined subjects most exposed to the risk of malnutrition.

RESULTS

An association between BMI and G8 (p < 0.001, OR 1.54) and a clinically significant relationship between G8 and PhA (p = 0.013) were observed.

CONCLUSION

G8 can be used to identify patients at risk for malnutrition who would benefit from comprehensive CGA. The concurrent use of G8 and BIA presents a higher power in discriminating subjects at higher risk of malnutrition than a single test. This study suggests the need for routine assessment of nutritional status in cancer patients using combinations of methods, in order to implement strategies for individually-tailored care before starting any treatment.

Predicting Risk of Severe Toxicity and Early Death in Older Adult Patients Treated with Chemotherapy

BACKGROUND

Determining the risk of grade 3-5 toxicity and early death (ED) is important to plan chemotherapy in older adult patients with cancer. Our objective was to identify factors predicting these complications at the time of treatment initiation.

METHODS

234 patients aged ≥70 were subjected to a geriatric assessment and variables related to the tumor and the treatment were also collected. Logistic regression multivariable analysis was used to relate these factors with the appearance of grade 3-5 toxicity and ED. Predictive scores for both toxicity and ED were then developed.

RESULTS

Factors related to grade 3-5 toxicity were hemoglobin, MAX2 index, ADL, and the CONUT score. Factors related to ED were tumor stage and the GNRI score. Two predictive scores were developed using these variables. ROC curves for the prediction of toxicity and ED were 0.71 (95% CI: 0.64-0.78) and 0.73 (95% CI: 0.68-0.79), respectively.

CONCLUSIONS

Two simple and reliable scores were developed to predict grade 3-5 toxicity and ED in older adult patients with cancer. This may be helpful in treatment planning.

Spinal metastases from non-small cell lung cancer - Is surgical extent enough by following suggestions of the Tomita and Tokuhashi scores?

BACKGROUND/OBJECTIVE

The Tomita, revised Tokuhashi and Tokuhashi lung scores are commonly used tools to predict the survival of patients with spinal metastases and to guide decisions regarding surgical treatment. These prognostic scores, however, tend to underestimate the prognosis of patients with lung cancer. We examined surgical outcome and hopefully provide a more accurate reference for management.

METHODS

The consistency between predicted and actual survival was examined using the Tomita and Tokuhashi scores. Various factors that may influence survival were analyzed. Primary outcomes were overall survival (OS) and progression-free survival (PFS), defined as the ambulatory time after the initial surgery. Secondary outcomes included reoperation events, blood loss, and hospitalization days.

RESULTS

One hundred seventy-two patients were enrolled. Correct survival predictions were made for 28%, 42%, and 56% with the Tomita, revised Tokuhashi, and Tokuhashi lung scores, respectively. The Tokuhashi lung scores underestimated OS by 35%-40%. Body mass index ≥20, systemic treatment-naïve, good general condition, the use of denosumab, and adenocarcinoma were found to positively affect OS and PFS. There was no significant difference between palliative decompression and excisional surgery regarding OS and PFS.

CONCLUSION

Patients with spinal metastases from lung cancer had better prognosis than that predicted by the Tomita and Tokuhashi scores. Spine surgeons should acknowledge this discrepancy and treat these patients with at least the aggressiveness suggested. Patients with adenocarcinoma, amenable to target therapy, denosumab, good general condition, systemic treatment-naïve are better candidates for surgery. Those with cachexic status and unresectable visceral metastases are worse candidates.

Update on the treatment of cancer cachexia

Cancer cachexia is a complex multifaceted syndrome involving functional impairment and changes in body composition that cannot be reversed by nutritional support. Cancer cachexia is characterized by decreased skeletal muscle mass, increased lipolysis, and decreased food intake. Cancer cachexia decreases chemotherapy tolerance as well as quality of life. However, because no fully effective interventions are available, cancer cachexia remains an unmet need in cancer treatment. In recent years, several discoveries and treatments for cancer cachexia have been studied, and guidelines have been published. We believe that the development of effective strategies for the diagnosis and treatment of cancer cachexia will lead to breakthroughs in cancer treatment.

Usefulness of the cachexia index as a prognostic indicator for patients with gastric cancer

Aim

Cachexia is associated with the morbidity and mortality of cancer patients. The cachexia index (CXI) is a novel biomarker of cachexia associated with the prognosis for certain cancers. This study analyzed the relationship between CXI with long-term outcomes of gastric cancer patients.

Methods

We included 175 gastric cancer patients who underwent curative gastrectomy at our hospital between January 2011 and October 2019. The CXI was calculated using skeletal muscle index, serum albumin level, and neutrophil-to-lymphocyte ratio. The prognostic value of CXI was investigated by univariate and multivariate Cox hazard regression models adjusting for potential confounders.

Results

In the multivariate analyses, tumor location (hazard ratio [HR], 0.23; 95% confidence interval [CI], 0.11-0.49; p < 0.01), disease stage (HR, 15.4; 95% CI, 4.18-56.1; p < 0.01), and low CXI (HR, 2.97; 95% CI, 1.01-8.15; p = 0.03) were independent and significant predictors of disease-free survival. Disease stage (HR, 9.88; 95% CI, 3.53-29.1; p < 0.01) and low CXI (HR, 4.07; 95% CI, 1.35-12.3; p < 0.01) were independent and significant predictors of overall survival. The low CXI group had a lower body mass index (p = 0.02), advanced disease stage (p = 0.034), and a lower prognostic nutritional index (p < 0.01).

Conclusions

Cachexia index is associated with a poor prognosis for gastric cancer, suggesting the utility of comprehensive assessment using nutritional, physical, and inflammatory status.

Cardioprotective Effects of the 4-Week Aerobic Running Exercises Before Treatment with Doxorubicin in Rats

Doxorubicin is associated with cardiotoxicity, and physical exercise seeks to minimize the toxic effects of doxorubicin through physiological cardiac remodeling, as well as the reduction of oxidative stress, evidenced by previous studies. This study aimed to analyze whether running training before treatment with doxorubicin influences tolerance to physical exertion and cardiotoxicity. Thirty-nine male Wistar rats, aged 90 days and weighing between 250 and 300 g, were divided into 4 groups: Control (C), Doxorubicin (D), Trained (T), and Trained + Doxorubicin (TD). Animals in groups T and DT were submitted to treadmill running for 3 weeks, 5 times a week at 18 m/min for 20-30 min before treatment with doxorubicin. Animals in groups D and DT received intraperitoneal injections of doxorubicin hydrochloride three times a week for two weeks, reaching a total cumulative dose of 7.50 mg/kg. Our results show an increase in total collagen fibers in the D group (p = 0.01), but no increase in the TD group, in addition to the attenuation of the number of cardiac mast cells in the animals in the TD group (p = 0.05). The animals in the TD group showed maintenance of tolerance to exertion compared to group D. Therefore, running training attenuated the cardiac damage caused by the treatment with doxorubicin, in addition to maintaining the tolerance to exertion in the rats.

Nutrition as prevention for improved cancer health outcomes: a systematic literature review

BACKGROUND

Among adults with cancer, malnutrition is associated with decreased treatment completion, more treatment harms and use of health care, and worse short-term survival. To inform the National Institutes of Health Pathways to Prevention workshop, "Nutrition as Prevention for Improved Cancer Health Outcomes," this systematic review examined the evidence for the effectiveness of providing nutrition interventions before or during cancer therapy to improve outcomes of cancer treatment.

METHODS

We identified randomized controlled trials enrolling at least 50 participants published from 2000 through July 2022. We provide a detailed evidence map for included studies and grouped studies by broad intervention and cancer types. We conducted risk of bias (RoB) and qualitative descriptions of outcomes for intervention and cancer types with a larger volume of literature.

RESULTS

From 9798 unique references, 206 randomized controlled trials from 219 publications met the inclusion criteria. Studies primarily focused on nonvitamin or mineral dietary supplements, nutrition support, and route or timing of inpatient nutrition interventions for gastrointestinal or head and neck cancers. Most studies evaluated changes in body weight or composition, adverse events from cancer treatment, length of hospital stay, or quality of life. Few studies were conducted within the United States. Among intervention and cancer types with a high volume of literature (n = 114), 49% (n = 56) were assessed as high RoB. Higher-quality studies (low or medium RoB) reported mixed results on the effect of nutrition interventions across cancer and treatment-related outcomes.

CONCLUSIONS

Methodological limitations of nutrition intervention studies surrounding cancer treatment impair translation of findings into clinical practice or guidelines.

[Nutritional supportive care in the course of patients with esophagogastric cancers]

Supportive care plays a central role in the management of patients with esophagogastric cancers, at all disease stages. Malnutrition has a high prevalence in this population, reaching up to 60 % of the patients. Sarcopenia and cachexia are also common. These complications have negative impact on functional abilities, quality of life and overall survival. They impair anti-tumor treatments effectiveness and increase their toxicity. Early detection and management are needed, before reaching advanced stages, which are refractory to therapeutic interventions. Specific nutritional support is recommended, relying on different nutritional support tools (dietetic counseling, oral supplements, artificial nutrition), depending on the clinical situation. When artificial nutrition is recommended, enteral nutrition (nasogastric tube, gastrostomy or jejunostomy) should be preferred. When enteral nutrition is impossible or insufficient, parenteral nutrition could be necessary. For patients with advanced esophagogastric cancers, digestive prostheses and decompressive radiation therapy may have a symptomatic benefit on dysphagia. Adapted physical activity is also recommended at all stages of cancer care and ongoing clinical trials will help to specify its modalities and to optimize its place in the therapeutic strategy. Finally, psychosocial support could be useful. A combined approach of these different interventions on the nutritional, physical and psychological aspects is beneficial for patients with esophagogastric cancers. This multimodal and multidisciplinary approach applies to both the early stages of the disease, with prehabilitation and/or rehabilitation to reduce perioperative morbidity and mortality and the advanced stages, with a benefit on survival and quality of life, in parallel with anti-tumor treatments.

Experiences and views of nurses about unmet needs of older cancer patients receiving chemotherapy: A qualitative study

OBJECTIVE

The aim is to understand the experiences and views of oncology nurses about the unmet care needs of older cancer patients receiving chemotherapy. Nurses play the key role in evaluating and determining the needs of this special group.

METHOD

A phenomenological descriptive qualitative study with convenience sampling was used. Participants were referred by the Turkish Oncology Nursing Society. The study participants were 12 nurses aged 34-53 years, with oncology experience between 5 and 27 years. The data were collected using semi-structured face-to-face interviews. Interviews were transcribed verbatim with concurrent analyses and data collection. Thematic content analysis was used to determine common domains.

RESULTS

The study data were categorized into 3 contexts, 12 themes, and 37 subthemes. The first context, "unmet needs", includes physical care, psychological care, and social care themes. The second context, "barriers to meeting those needs", comprises the theme of patient characteristics, attitude of family, attitude of the nurses/healthcare team, health system, and culture. The last context is "suggestions for meeting needs". Nurses play an important role in identifying and meeting unmet psychosocial needs.

SIGNIFICANCE OF RESULTS

The study indicated that older cancer patients had problems in identifying, expressing, and making demands for their needs and that their culture contributed to this situation. Nurses serving in the outpatient chemotherapy units should conduct a holistic assessment of older cancer patients, be aware that these patients may not be able to express their needs, be more sensitive toward them, and ensure that the voice of the older patients is heard.

Loss of body weight and skeletal muscle negatively affect postoperative outcomes after major abdominal surgery in geriatric patients with cancer

OBJECTIVES

Malnutrition characterized by the involuntary loss of body weight and skeletal muscle can be the result of both aging and malignancy. As a result, geriatric patients could face an increased nutritional risk. This study aimed to investigate the nutritional and functional status of geriatric patients and their association with postoperative complications.

METHODS

Patients who underwent abdominal surgery for digestive cancer in our center between January 2020 and August 2021 were included in the study. Computed tomography scans were collected to evaluate muscle mass and density. Changes in body weight, muscle strength, physical performances, nutritional risk, and status were evaluated upon admission. Postoperative outcomes collected included postoperative length of stay, complications, and 30-d readmission.

RESULTS

A total of 1513 patients were included for the analysis. Of these, 72.8% were at risk for malnutrition (70.3% in the non-geriatric group and 75.4% in the geriatric group; P = 0.031), and 28.9% had malnutrition according to the Subjective Global Assessment (26.0% in the non-geriatric group and 31.8% in the geriatric group; P = 0.016). Compared with younger patients, geriatric patients have decreased muscle mass (skeletal muscle index, 44.8 versus 47.4; P < 0.001) and skeletal muscle density. Significant weight loss and loss of skeletal muscle occurred concurrently in 18.8% of the patients and were more frequent in the geriatric group (22.3% versus 14.7%; P < 0.001). In multivariate analysis, an age of 65 y or older (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.07-1.86; P = 0.014), a serum albumin level ≤4.11 g/dL (OR, 1.35; 95% CI, 1.03-1.77; P = 0.03), skeletal muscle loss (OR, 1.69; 95% CI, 1.28-2.24; P < 0.001), declined functional status (OR, 1.5; 95% CI, 1.14-1.98; P = 0.004), systematic inflammation (OR, 1.71; 95% CI, 1.09-2.8; P = 0.026), and significant weight loss (OR, 1.4; 95% CI, 1.06-2.85; P = 0.017) were independent predictors of overall postoperative complications. Although there was a trend of interactions between advanced age, skeletal muscle loss, and significant weight loss, multivariate analysis showed none of the interactions were significantly predictive of overall postoperative complications.

CONCLUSIONS

Geriatric patients are at greater risk for malnutrition. Their declined nutritional and functional status together with advanced age could increase the risk for postoperative complications. Nutrition evaluation should be part of the preoperative workup, and timely interventions should be initiated if needed, especially in geriatric patients.

Inoperable Bowel Obstruction in Ovarian Cancer: Prevalence, Impact and Management Challenges

Malignant bowel obstruction (MBO) is one of the most severe complications in patients with advanced ovarian cancer, with an estimated incidence up to 50%. Its presence is related to poor prognosis and a life expectancy measured in weeks for inoperable cases. Symptoms are usually difficult to manage and often require hospitalization, which carries a high burden on patients, caregivers and the healthcare system. Management is complex and requires a multidisciplinary approach to improve clinical outcomes. Patients with inoperable MBO are treated medically with analgesics, antiemetics, steroids and antisecretory agents. Parenteral nutrition and gut decompression with nasogastric tube, venting gastrostomy or stenting may be used as supportive therapy. Treatment decision-making is challenging and often based on clinical expertise and local policies, with lack of high-quality evidence to optimally standardize management. The present review summarizes current literature on inoperable bowel obstruction in ovarian cancer, focusing on epidemiology, prognostic factors, clinical outcomes, medical management, multidisciplinary interventions and quality of life.

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

OBJECTIVES

The aim of the present study was to clarify the effect of malnutrition as defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria on compliance with postoperative adjuvant chemotherapy and relapse-free survival (RFS) in patients with gastric cancer.

METHODS

This single-center, retrospective cohort study included 281 consecutive patients with gastric cancer who underwent radical gastrectomy for pathologic stages II and III and received postoperative S-1 adjuvant chemotherapy between April 2008 and June 2018. Treatment failure was defined as discontinuation of adjuvant chemotherapy ≤1 y. Nutritional assessment was preoperatively performed according to the GLIM criteria for all patients. We analyzed risk factors for treatment failure and poor prognostic factors for RFS using multivariate analyses.

RESULTS

Treatment failure and recurrence were observed in 50 (17.8%) and 97 (34.5%) of the 281 patients, respectively. The median follow-up period was 52 mo. The treatment failure rate was higher (P = 0.032) and RFS was worse (P = 0.017) in the malnutrition group. In multivariate analyses, GLIM criteria-defined malnutrition was an independent risk factor for treatment failure (odds ratio = 3.110; 95% confidence interval [CI], 1.020-9.470; P = 0.046). Furthermore, severe malnutrition was an independent poor prognostic factor for RFS (hazard ratio = 1.767; 95% CI, 1.132-2.759; P = 0.012).

CONCLUSIONS

Preoperative malnutrition as defined by the GLIM criteria was an independent risk factor for poor compliance with adjuvant S-1 chemotherapy and a poor prognostic factor for RFS after radical gastrectomy in patients with advanced gastric cancer. <END ABSTRACT>.

In vitro chemotherapy-associated muscle toxicity is attenuated with nutritional support, while treatment efficacy is retained

Purpose: Muscle-wasting and treatment-related toxicities negatively impact prognosis of colorectal cancer (CRC) patients. Specific nutritional composition might support skeletal muscle and enhance treatment support. In this in vitro study we assess the effect of nutrients EPA, DHA, L-leucine and vitamin D3, as single nutrients or in combination on chemotherapy-treated C2C12-myotubes, and specific CRC-tumor cells.

Materials and Methods: Using C2C12-myotubes, the effects of chemotherapy (oxaliplatin, 5-fluorouracil, oxaliplatin+5-fluorouracil and irinotecan) on protein synthesis, cell-viability, caspase-3/7-activity and LDH-activity were assessed. Addition of EPA, DHA, L-leucine and vitamin D3 and their combination (SNCi) were studied in presence of above chemotherapies. Tumor cell-viability was assessed in oxaliplatin-treated C26 and MC38 CRC cells, and in murine and patient-derived CRC-organoids.

Results: While chemotherapy treatment of C2C12-myotubes decreased protein synthesis, cell-viability and increased caspase-3/7 and LDH-activity, SNCi showed improved protein synthesis and cell viability and lowered LDH activity. The nutrient combination SNCi showed a better overall performance compared to the single nutrients. Treatment response of tumor models was not significantly affected by addition of nutrients.

Conclusions: This in vitro study shows protective effect with specific nutrition composition of C2C12-myotubes against chemotherapy toxicity, which is superior to the single nutrients, while treatment response of tumor cells remained.

Supplemental parenteral nutrition in cancer care: why, who, when

Malnutrition is an often-overlooked challenge for patients with cancer. It is associated with muscle mass reduction, poor compliance and response to cancer treatments, decreased quality of life, and reduced survival time. The nutritional assessment and intervention should be a vital part of any comprehensive cancer treatment plan. However, data on artificial nutrition supplied based on caloric needs during cancer care are scarce. In this review, we discuss the recommendations of the European and American societies for clinical nutrition on the use of nutritional interventions in malnourished patients with cancer in the context of current clinical practice. In particular, when enteral nutrition (oral or tube feeding) is not feasible or fails to meet the complete nutritional needs, supplemental parenteral nutrition (SPN) can bridge the gap. We report the available evidence on SPN in cancer patients and identify the perceived barriers to the wider application of this intervention. Finally, we suggest a ‘permissive’ role of SPN in cancer care but highlight the need for rigorous clinical studies to further evaluate the use of SPN in different populations of cancer patients.

The feasibility of screening for malnutrition in the outpatient setting and the prevalence of malnutrition in patients with newly-diagnosed ovarian carcinoma

•

Malnutrition screening of outpatients in a Gynecologic Oncology clinic setting is feasible.

•

Malnutrition was infrequently detected through outpatient screening of new patients with suspected gynecologic malignancy.

•

The prevalence of malnutrition in individuals with newly-diagnosed ovarian cancer is low.

•

Optimizing nutrition remains important, especially later in the cancer course when malnutrition is likely more prevalent.

Falls in older ambulatory care patients with cancer in Iran: Implications for clinical practice

RATIONALE/AIM

Falls can have severe consequences particularly for older patients with cancer undergoing ambulatory care. The aim of the study is to identify the predictors of falls in older patients receiving cancer ambulatory care and evaluate the accuracy of the final multivariable model in detecting older patients with falls.

METHOD

A retrospective study was conducted on 300 older patients aged 60 years and above that were referred for ambulatory care in three oncology clinics based at hospitals in Tehran, Iran. Participants completed a questionnaire comprising demographic, history of falls, and cancer-related factors. Logistic regression was used to determine risk factors associated with falls.

RESULTS

A total of 35.3% of the older patients with cancer had experienced a fall in the 6 months following the start of their ambulatory care. The most important predictors of falls include the fourth stage of cancer (odds ratio [OR]: 6.47, 95% confidence interval [CI]: 3.20-13.08, p < 0.001), fear of falling (OR: 5.64, 95% CI: 2.58-12.33, p < 0.001), use of hearing (OR: 2.38, 95% CI: 1.07-5.29, p = 0.033) and visual aids (OR: 2.36, 95% CI: 1.12-5.01, p = 0.025), and the number of visits to the doctor (OR: 1.10, 95% CI: 1.01-1.21, p = 0.035).

CONCLUSIONS

The results indicate that a reduction in falls is possible by introducing strategies to improve care for older patients in the advanced stage of cancer, eliminating the causes of fear of falling, examining and improving vision and hearing, and identifying and addressing the underlying causes of visits to the doctor.

Optimal Frailty Dimensions for Assessing Frailty and Predicting Chemotherapy Adverse Events in Older Taiwanese Cancer Patients

Background

This study aimed to investigate the effects of different frailty dimensions on frailty prevalence in older Taiwanese cancer patients receiving chemotherapy, and to analyze the dimensions that should be included in frailty assessment for effectively predicting serious adverse events, unexpected hospitalizations, and emergency department visits.

Materials and Methods

This study prospectively enrolled 234 cancer patients with solid cancer or lymphoma and aged 65 years or older who later received chemotherapy at a medical center in Taiwan from September 2016 to November 2018. First, all patients were subjected to a frailty assessment on eight frailty dimensions within 1 week before their first chemotherapy treatment. The effects of different dimensions on frailty were analyzed using a Poisson regression model. Second, after sequentially excluding one, two, and three dimensions with the lowest effects, frailty was sequentially assessed in the remaining seven, six, and five dimensions for comparison of chemotherapy-related adverse events.

Results

Nutritional status, comorbidity, history of falls, cognitive status, and polypharmacy were the top five important dimensions of frailty in older Taiwanese cancer patients. Regardless of the number (five to eight) of dimensions used for frailty assessment, frail patients had higher rates of serious adverse events, unexpected hospitalizations, and emergency room visits than non-frail patients during chemotherapy.

Conclusions

Frailty assessment in older Taiwanese cancer patients should be based on at least five dimensions to accurately identify those at high risk of serious adverse events during chemotherapy. It is expected that the present findings may be used to design a frailty scale for older Taiwanese in the future.

MASCC multidisciplinary evidence-based recommendations for the management of malignant bowel obstruction in advanced cancer

PURPOSE

To provide evidence-based recommendations on the management of malignant bowel obstruction (MBO) for patients with advanced cancer.

METHODS

The Multinational Association for Supportive Care in Cancer (MASCC) MBO study group conducted a systematic review of databases (inception to March 2021) to identify studies about patients with advanced cancer and MBO that reported on the following outcomes: symptom management, bowel obstruction resolution, prognosis, overall survival, and quality of life. The review was restricted to studies published in English, but no restrictions were placed on publication year, country, and study type. As per the MASCC Guidelines Policy, the findings were synthesized to determine the levels of evidence to support each MBO intervention and, ultimately, the graded recommendations and suggestions.

RESULTS

The systematic review identified 17,656 published studies and 397 selected for the guidelines. The MASCC study group developed a total of 25 evidence-based suggestions and recommendations about the management of MBO-related nausea and vomiting, bowel movements, pain, inflammation, bowel decompression, and nutrition. Expert consensus-based guidance about advanced care planning and psychosocial support is also provided.

CONCLUSION

This MASCC Guideline provides comprehensive, evidence-based recommendations about MBO management for patients with advanced cancer.
