The role of nutrition in children with cancer

Age-stratified validation and interrater reliability of the screening tool for nutritional risk for childhood cancer in hospitalized children

OBJECTIVE

To evaluate the reliability, construct, and criterion validity of the screening tool for childhood cancer (SCAN), stratified by age in oncology patients admitted to a tertiary referral hospital.

METHODS

Hospitalized children from birth to 18 years old, with an oncological diagnosis and expected length of stay (LOS) of >24 hours were included. Interrater and intrarrater agreements were used to evaluate the reliability of SCAN. Construct validity and criterion validity were explored in SCAN. Also, predictive validity was explored by comparing SCAN risk categories against LOS.

RESULTS

Three hundred ninety-four children were included in the study. The scores obtained after dietitians and physicians used SCAN showed good agreement (ICC = 0.80, 95%CI 0.71-0.86, P < 0.001). The intrarrater agreement within the evaluation of the same dietitian to the same group of patients was also good (ICC = 0.83, 95%CI 0.75-0.88, P < 0.001). After applying SCAN, 66.2% of participants scored >3 points, classified as at risk of malnutrition. The agreement observed when comparing the risk classification given by the tool with the malnutrition assessment using anthropometry variables as the criterion reference was fair (κ = 0.22, 95%CI 0.15-0.29, P < 0.001). Predictive validity indicated a slight agreement (κ = 0.16, 95%CI 0.08-0.25, P < 0.001) between malnutrition risk by SCAN and LOS. When assessing construct validity, comparing the scores given by SCAN with those provided by STRONGkids, a fair agreement was found (κ = 0.21, 95%CI 0.15-0.26, P < 0.001).

CONCLUSIONS

Our results show that SCAN is a reliable and valid tool for detecting malnutrition in oncology pediatric patients upon hospital admission.

Nutritional status at diagnosis and its relationship with survival and relapse in Mexican children with acute lymphoblastic leukemia: a retrospective study

BACKGROUND & AIMS

Childhood acute lymphoblastic leukemia (ALL) is a malignancy with varying survival rates across countries with low, middle, and high income. The assessment of nutritional status (NS) using anthropometric indicators has been explored for its potential relationship on treatment outcomes. This study analyzed a 3-year retrospective cohort of Mexican pediatric patients with ALL, exploring the association between NS at diagnosis and relapse/mortality.

METHODS

Retrospective observational study. Medical records from 252 pediatric patients with ALL were included; anthropometric indicators (Z-scores) of body weight, height, mid-upper arm circumference (MUAC), and triceps and subscapular skinfolds (TSF and SSF, respectively) measurements were used to assess NS. The relapse/mortality data were collected from medical records. Kaplan-Meier (KM) functions and Cox regression models were performed to evaluate the effect of indicators on survival, relapse, and event (death or disease relapse).

RESULTS

Patients with malnutrition showed a significantly lower survival rate according to their BMI (76% vs 63%, p = 0.049), while relapses were higher in the group with TSF < -2 SD (41% vs 12%, p = 0.007). Patients with stunting and TSF < -2 SD showed a higher risk of mortality (HR:6.214, 95%CI: 1.372 to 28.154; HR:2.91, 95%CI: 1.27 to 6.68, respectively), while in patients with higher MUAC Z-score showed a decrease in the mortality risk (HR:0.85, 95%CI:0.73 to 1.00).

CONCLUSIONS

The nutritional status assessed by anthropometric measurements was a strong predictor of survival and relapse outcomes 3y post/diagnosis in this cohort of pediatric patients with ALL.

The evolution of nutritional care in children and young people with acute lymphoblastic leukaemia: a narrative review

BACKGROUND

Acute lymphoblastic leukaemia (ALL) is the most common paediatric malignancy in the world. Advances in treatment protocols have resulted in survival rates of >80% in most high-income countries (HIC); however, children and young people (CYP) with ALL continue to face significant nutrition-related challenges during treatment.

METHODS

This narrative review outlines the changing landscape of treatment and survivorship for CYP with ALL and the advances in nutrition knowledge that call for changes to clinical nutrition practice.

RESULTS

The incidence of ALL has remained stable in HIC; however, there have been significant advances in survival over the past 30 years. Overweight and obesity are increasingly prevalent in CYP with ALL at diagnosis, during treatment and in survivorship. Coupled with poor diet quality, high-energy and saturated fat intakes, altered eating behaviours and inactivity, this necessitates the need for a shift in nutrition intervention. Undernutrition remains a concern for CYP with high-risk treatment protocols where oral or enteral nutrition support remains a cornerstone of maintaining nutrition status.

CONCLUSIONS

With improved treatment protocols and high survival rates, a shift to focusing on diet quality, prevention of excessive weight gain and obesity during treatment and survivorship is necessary.

The association between nutrition risk status assessment and hospital mortality in Chinese older inpatients: a retrospective study

PURPOSE

The association between nutritional risk status assessment and hospital mortality in older patients remains controversial. The aim of this study was to assess the relationship between nutritional risk on admission and in-hospital mortality, and explore the best Nutritional Risk Status Screening 2002 (NRS2002) threshold for predicting in-hospital mortality of older inpatients in China.

METHOD

The elderly inpatients were recruited from a hospital in Hunan Province, China. Nutritional risk was screened and assessed using the NRS2002. Logistic regression was used to analyze whether NRS2002 scores were independently associated with hospital mortality, and the results were expressed as odds ratios (OR) and 95% confidence intervals (CIs). Receiver operating characteristic curve (ROC) was used to determine the best NRS2002 threshold for predicting in-hospital mortality in elderly inpatients. And 500 bootstrap re-samplings were performed for ROC analysis.

RESULT

In total, 464 elderly inpatients completed the survey (15 of whom died, 205 males and 259 females, mean age = 72.284 ± 5.626 years). Multifactorial analysis revealed that age, the NRS2002 score, and length of hospital stay significantly influenced in-hospital mortality among older inpatients (P < 0.05). The results also showed that higher NRS2002 scores were associated with an increased risk of in-hospital mortality in both the unadjusted (OR = 1.731,95%CI = 1.362-2.20, P < 0.0001), adjusted model I (OR = 1.736, 95% CI = 1.354-2.206, P < 0.0001) and model II (OR = 1.602, 95% CI = 1.734-2.488, P = 0.0005). The optimal NRS2002 threshold for predicting in-hospital mortality in older inpatients was 3.5, with the largest ROC area of 0.84.

CONCLUSION

Our findings indicated that nutritional risk was an independent predictor of in-hospital mortality, with a cut-off value of 3.50 for the NRS2002 nutritional risk assessment being more appropriate than a cut-off value of 3.0.

Validity of a nutrition screening tool for childhood cancer

BACKGROUND

Malnutrition in pediatric oncology patients is a serious clinical condition. There is a need for standardized nutrition screening in pediatric oncology patients, as nutrition screening can offer a simple method to identify children with cancer at risk of malnutrition. This study aimed to determine the validity of a Turkish version of nutrition screening tool for childhood cancer (SCAN) in identifying the risk of malnutrition among children with cancer.

MATERIALS AND METHODS

A cross-sectional study was conducted with 78 children with cancer admitted to the pediatric hematology-oncology unit of a university hospital. In the first stage of this study, SCAN was translated into Turkish, and in the second stage, the validity of SCAN against pediatric Subjective Global Nutritional Assessment (SGNA) and Academy of Nutrition and Dietetics/American Society for Parenteral and Enteral Nutrition (AND/ASPEN) malnutrition criteria were evaluated.

RESULTS

Patients had a median age of 8.0 years (range, 2-18 years; IQR, 5-14 years), 61.5% were male, and 60.3% were diagnosed with leukemia. According to SCAN, 53.8% had high risk of malnutrition. Validation of SCAN against pediatric SGNA showed that SCAN has a sensitivity of 97.5%, specificity of 94.5%, and accuracy of 96.1%.

CONCLUSION

The risk of malnutrition is common in children with cancer. The Turkish version of the SCAN is a simple, quick, and valid tool to determine the risk of malnutrition in children with cancer. Further research is needed to understand the impact of nutrition interventions on clinical outcomes in children at risk for malnutrition based on SCAN.

Knowledge, attitudes, and practices of primary caregivers of gastric cancer patients regarding postoperative dietary management

BACKGROUND

Family caregivers of gastric cancer (GC) patients after gastrectomy have a strong demand for nutrition knowledge. This study investigates the knowledge, attitudes, and practices (KAP) of primary caregivers of GC patients regarding postoperative dietary management.

METHODS

We conducted a cross-sectional study, collecting data through questionnaire distribution. Demographic information of the respondents and KAP scores were assessed and analyzed.

RESULTS

Of 508 included participants, majority were female (59.84%) urban residents (78.94%), aged 40-60 years (53.15%). Caretakers were primarily spouses of GC patient (50.39%) or parents (10.43%), only child (12.99%) or non-only child (24.21%). Notable percentage of poor knowledge and practice was found among participants (45.05% and 40.55%, respectively), while attitude was predominantly positive (99.41%). Correlation analysis revealed a weak positive correlation between knowledge and attitude scores (r = 0.150, P < 0.001) and negative link to practice scores (r=-0.228, P < 0.001); attitude scores were positively correlated with practice (r = 0.117, P = 0.008). Multivariate logistic regression analysis found that higher attitude scores were independently associated with higher practice scores (OR = 1.360; 95%CI, 1.223-1.513), P < 0.001), while higher knowledge scores (OR = 0.684; 95%CI, 0.575-0.815), P < 0.001), older age (OR = 0.951; 95%CI, 0.918-0.985), P = 0.005), duration of caregiving > 3 months (3-6 months (OR = 0.415; 95%CI, 0.193-0.894, P = 0.025); 6 months-1 year (OR = 0.269; 95%CI, 0.120-0.606), P = 0.002); >1 year (OR = 0.290; 95%CI, 0.120-0.705), P = 0.006), and follow-up location after patient's surgery (OR = 0.072 (0.033-0.160), P < 0.001) were independently associated with lower practice scores.

CONCLUSIONS

Family caregivers of GC patients that participated in this study demonstrated moderate knowledge and practice, but positive attitude towards dietary management after gastrectomy.

Prevalence of Undernutrition Among Children and Adolescents with Cancer Living in Sub-Saharan African Countries: A Systematic Review and Meta-analysis

Objective. To systematically review studies to provide the pooled estimate of undernutrition among children and adolescents with cancer living in sub-Saharan African countries. Methods. The review followed the recommendations outlined in the PRISMA statement. Online searches were performed on electronic databases such as PubMed, Scopus, Embase, and Hinari; gray literature sources: such as Google, Google Scholar, and university repositories were also searched. A random effect model was used to drive the pooled prevalence, and was reported at a 95% Confidence Interval (CI). Heterogeneity was assessed using subgroup analysis and univariable meta-regression. The effect of each study on the overall prevalence was assessed using leave-one-out sensitivity analysis. In all the models, statistical significance was set at P-value <.05. Result. A total of 623 articles were identified, and 21 articles were retrieved for the final analysis. The overall pooled prevalence of undernutrition was 41.34% (95% CI: 31.64%, 51.04%). The highest prevalence of undernutrition was observed from studies that used Arm Muscle Area (AMC) for age to assess undernutrition: 61.66% (95% CI: 47.59%, 75.72%). The protocol for this review has been registered at PROSPERO (CRD42024510052). Conclusion. The prevalence of undernutrition in sub-Saharan African countries was considerably high. Therefore, policy directions and cost-effective approaches that sustainably address undernutrition among pediatric patients with cancers are needed.

Perception of Paediatricians and Families about Nutritional Supplements: Acceptance, Tolerability and Satisfaction in Malnourished Children (PerceptiONS Jr Study)

BACKGROUND

Malnutrition is a common situation in the Spanish paediatric population. Malnourished children may benefit from different strategies, including dietary modifications or nutritional supplements (NS). It is important to know the different factors that can influence treatment tolerance and adherence, and their impact on nutrition monitoring.

OBJECTIVES

To explore the perception of doctors who prescribe nutritional supplements (NS) in children and to investigate different factors involved in tolerance and adherence.

MATERIAL AND METHODS

A cross-sectional, descriptive observational study based on an ad hoc electronic survey designed to study doctors' perceptions of at least five of their children with NS and their families, subjected to outpatient follow up. Variables included were the socio-demographic variables of the doctors and children, nutritional status of the patients, amount and characteristics of NS (hyper-caloric oral with fibre (HOFF), oral peptide (OPF) and hyper-caloric infant (HIF)), route of administration, perceived benefits, satisfaction, palatability, adherence, and acceptance.

RESULTS

815 patients aged 0-16 years (mean 10.6 years; SD 7.8) were included. A proportion of 64% received HOFF, 16% FOP, and 20% HIF. A proportion of 84% received exclusive oral NS. Total daily calorie intake prescribed with NS ranged from 30-75% in 48.2% of cases, though it was significantly higher in children under 6 months of age. Improvement in overall condition, nutritional status and quality of life was observed in 82%, 79.5%, and 80% of subjects. Improvement in tolerance and digestive symptoms was reported in 83.5% and 72% of subjects. The degree of satisfaction and acceptance of NS was very good in 80% of cases, with taste being the most influential factor (82.3%). Adherence was adequate in more than 60%, and smell was the most significant feature in lack of adherence (55%). The flavour of the best-accepted supplement was chocolate (44%). A total of 97% of prescribing doctors would recommend the same formula again.

CONCLUSIONS

In our study, prescribing doctors and families perceived an excellent benefit from the use of the prescribed formulas, improved quality of life, high satisfaction, acceptance, and adherence. The positive factors for adequate adherence were sufficient information about the formulations and their benefits, and continuity of care during follow-up. Prescribing doctors would recommend supplement use again given the perceived benefits and satisfaction.

Nutritional interventions in children with acute lymphoblastic leukemia undergoing antineoplastic treatment: a systematic review

BACKGROUND

A compromised nutritional status jeopardizes a positive prognosis in acute lymphoblastic leukemia (ALL) patients. In low- and middle-income countries, ~ 50% of children with ALL are malnourished at diagnosis time, and undergoing antineoplastic treatment increases the risk of depleting their nutrient stores. Nutrition interventions are implemented in patients with cancer related malnutrition. We aimed to evaluate the effect of nutrition interventions in children diagnosed with ALL under treatment.

METHODS

Using a predefined protocol, we searched for published or unpublished randomized controlled trials in: Cochrane CENTRAL, MEDLINE, EMBASE, LILACS, and SciELO, and conducted complementary searches. Studies where at least 50% of participants had an ALL diagnosis in children ≤ 18 years, active antineoplastic treatment, and a nutrition intervention were included. Study selection and data extraction were conducted independently by three reviewers, and assessment of the risk of bias by two reviewers. Results were synthesized in both tabular format and narratively.

RESULTS

Twenty-five studies (out of 4097 records) satisfied the inclusion requirements. There was a high risk of bias in eighteen studies. Interventions analyzed were classified by compound/food (n = 14), micronutrient (n = 8), and nutritional support (n = 3). Within each group the interventions and components (dose and time) tested were heterogeneous. In relation to our primary outcomes, none of the studies reported fat-free mass as an outcome. Inflammatory and metabolic markers related to nutritional status and anthropometric measurements were reported in many studies but varied greatly across the studies. For our secondary outcomes, fat mass or total body water were not reported as an outcome in any of the studies. However, some different adverse events were reported in some studies.

CONCLUSIONS

This review highlights the need to conduct high-quality randomized controlled trials for nutrition interventions in children with ALL, based on their limited number and heterogeneous outcomes.

The importance of basic and translational research in caring for children with malignant solid tumors in Latin America

Objective

Basic and translational research in pediatric cancer are essential to improve patient care. To critically assess the developments achieved in these areas in Latin America, we systematically reviewed information published between 2013 and 2023.

Methods

Studies of basic and translational research performed by investigators in Latin America evaluating pediatric malignant solid and central nervous system tumors were retrieved from PubMed. Original articles published in English between 2013 and 2023 were included. Collaborations among Latin American authors or among Latin American authors working with researchers from other continents were also included. Studies were excluded if they focused only on adults or on basic research in tumor biology not specifically related to the tumor types analyzed in this review.

Results

A total of 550 articles were retrieved, but after removal of duplicates, 514 articles were included in the analysis, the majority of which were authored by researchers affiliated with institutions in Argentina, Brazil and Mexico. These countries also had the highest number of collaborations on original articles published with authors from Europe and North America. Argentina had the highest number of collaborations on original publications, with coauthors from Brazil and Uruguay. The median impact factor of the 244 journals in which articles were published was 3.5. The most commonly studied tumors were osteosarcomas, neuroblastomas and medulloblastomas; the most commonly studied areas were molecular analysis, tumor cell biology and biomarkers.

Conclusions

In Latin America, research in pediatric oncology is on the agenda, despite a notable disparity in publication rates and frequency of collaboration between countries. There is a need to strengthen scientific collaboration within Latin America and with countries from other continents to promote research and to develop novel treatment strategies that reflect the local needs of children in Latin America who have solid tumors and brain cancer.

Clinical effects and safety of semi-solid feeds in tube-fed patients: a meta-analysis and systematic review

Background

Enteral nutrition is a very important form of treatment for critically ill patients. This meta-analysis aimed to evaluate the clinical effects and safety of semi-solid feeds in tube-fed patients.

Methods

Two researchers searched PubMed, clinical trials, Embase, Cochrane Central Register of Controlled Trials, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and Weipu databases for randomized controlled trials (RCTs) on the clinical effects and safety of semi-solid feeds in tube-fed patients until 10 October 2023. The quality evaluation tool recommended by the Cochrane Library was used to evaluate the quality of included RCTs. RevMan 5.4 software was used for data analysis.

Results

A total of eight RCTs involving 823 tube-fed patients were included in this meta-analysis. A synthesized outcome indicated that semi-solid feeds reduced the incidence of diarrhea (RR = 0.32, 95%CI:0.20-0.50, P < 0.001), vomiting (RR = 0.31, 95%CI:0.15-0.64, P = 0.002), abdominal distension (RR = 0.41, 95%CI:0.22-0.76, P = 0.005), length of intensive care unit (ICU) stay (MD = -3.61, 95%CI: -6.74 to -0.48, P = 0.02), and length of hospital stay (MD = -7.14, 95%CI: -10.31 to -3.97, P < 0.01) in tube-fed patients. Enteric feeding had no effect on the 30-day mortality (RR = 0.55, 95%CI: 0.19-1.56, P = 0.26). No publication bias was detected by the Egger's test results (all P > 0.05).

Conclusion

Semi-solid feeds are beneficial in reducing the incidence of diarrhea, abdominal distension, vomiting, and hospital stay. More high-quality studies are needed in the future to verify the effects of semi-solid feeds on mortality.

Nutritional status, body composition and diet quality in children with cancer

During cancer treatment, nutritional status disorders such as malnutrition or obesity affect the tolerance of cancer treatment, quality of life, but also the pharmacokinetics of drugs. It is hypothesized that changes in fat and lean body mass can modify chemotherapy volume distribution, metabolism and clearance. In children with cancer, lean body mass decreases or remains low during treatment and fat mass increases. Body composition is influenced by the cancer itself, aggressive multimodal-therapies, changes in metabolism, unbalanced diet and reduced physical activity. Due to the side effects of treatment, including changes in the sense of taste and smell, nausea, vomiting, diarrhea, and stress, eating according to recommendation for macronutrients and micronutrients is difficult. Research indicates that throughout cancer treatment, the consumption of fruits, vegetables, and dairy products tends to be insufficient, whereas there is an elevated intake of sugar and unhealthy snacks. Children exhibit a preference for high-carbohydrate, salty, and strongly flavored products. This review revealed the importance of body composition and its changes during cancer treatment in children, as well as eating habits and diet quality.

More than a small adult brain: Lessons from chemotherapy-induced cognitive impairment for modelling paediatric brain disorders

Childhood is recognised as a period of immense physical and emotional development, and this, in part, is driven by underlying neurophysiological transformations. These neurodevelopmental processes are unique to the paediatric brain and are facilitated by augmented rates of neuroplasticity and expanded neural stem cell populations within neurogenic niches. However, given the immaturity of the developing central nervous system, innate protective mechanisms such as neuroimmune and antioxidant responses are functionally naïve which results in periods of heightened sensitivity to neurotoxic insult. This is highly relevant in the context of paediatric cancer, and in particular, the neurocognitive symptoms associated with treatment, such as surgery, radio- and chemotherapy. The vulnerability of the developing brain may increase susceptibility to damage and persistent symptomology, aligning with reports of more severe neurocognitive dysfunction in children compared to adults. It is therefore surprising, given this intensified neurocognitive burden, that most of the pre-clinical, mechanistic research focuses exclusively on adult populations and extrapolates findings to paediatric cohorts. Given this dearth of age-specific research, throughout this review we will draw comparisons with neurodevelopmental disorders which share comparable pathways to cancer treatment related side-effects. Furthermore, we will examine the unique nuances of the paediatric brain along with the somatic systems which influence neurological function. In doing so, we will highlight the importance of developing in vitro and in vivo paediatric disease models to produce age-specific discovery and clinically translatable research.

Children's Oncology Group's 2023 blueprint for research: Cancer control and supportive care

The objective of the Cancer Control and Supportive Care (CCL) Committee in the Children's Oncology Group (COG) is to reduce the overall morbidity and mortality of therapy-related toxicities in children, adolescents, and young adults with cancer. We have targeted five major domains that cause clinically important toxicity: (i) infections and inflammation; (ii) malnutrition and metabolic dysfunction; (iii) chemotherapy-induced nausea and vomiting; (iv) neuro- and oto-toxicty; and (v) patient-reported outcomes and health-related quality of life. Subcommittees for each domain prioritize randomized controlled trials and biology aims to determine which strategies best mitigate the toxicities. The findings of these trials are impactful, informing clinical practice guidelines (CPGs) and directly leading to changes in the standard of care for oncology practice. With the development of new therapies, there will be new toxicities, and the COG CCL Committee is dedicated to developing interventions to minimize acute and delayed toxicities, lessen morbidity and mortality, and improve quality of life in pediatric and young adult patients with cancer.

Anthropometric Outcomes in Survivors of Pediatric Solid Tumors

Nutritional status is an important aspect of childhood cancer, with a bearing on the disease and subsequent survivorship. We sought to evaluate the long-term anthropometric outcomes in a cohort of pediatric solid tumor survivors treated between 1994 and 2016. Anthropometry was noted at the time of presentation, after completion of therapy, and at the last follow-up. The z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated using WHO growth charts for ages <5 years and the Indian Academy of Pediatrics growth charts for age >/= 5 years. BMI was calculated for adult survivors. We included 317 survivors, comprising 48, 81, and 188 survivors of Hepatoblastoma (HB), Malignant Germ cell Tumor (MGCT), and Wilms Tumor (WT) respectively. The median age at diagnosis was 24.5 (IQR 59-13.2) months, with a follow-up ranging from 5 to 19.54 years. The z-scores of the collective cohort and individual cohorts of HB, MGCT, and WT showed an improving trend from diagnosis to the last follow-up. The difference in the prevalence of malnutrition was found to be statistically significant when any two-time points were compared. Of the 28 adult survivors, 43% were noted to be underweight. Thus, anthropometric measures improve during follow-up, however, up to 15% of children persist in being malnourished.

Role of Nutrition in Pediatric Patients with Cancer

Children with cancer are at high risk for developing short-term and long-term nutritional problems related to their underlying disease and side effects of multimodal treatments. Nutritional status (NS) can influence several clinical outcomes, such as overall survival (OS) and event-free survival (EFS), treatment tolerance, risk of developing infections and quality of life (QoL). However, the importance of nutrition in children with cancer is still underestimated. This review focuses on alterations of NS that occurs in children during cancer treatment. In particular, we reviewed the pathogenesis of undernutrition in oncological children, as well as how NS affects treatment tolerance and response, the immune system and the risk of infections of children with cancer. Thanks to recent advances in all types of supportive therapy and to the progress of knowledge on this topic, it has been realized that NS is a modifiable prognostic factor that can be intervened upon to improve the outcome of these patients. Currently, there is a lack of a systematic approach and standard recommendations for nutritional care in the pediatric cancer population. Literature analysis showed that it is essential to define the NS and treat any alterations in a timely manner ensuring proper growth and development. Nutritional follow-up should become an integral part of the care pathway. Regular nutritional monitoring should be performed at diagnosis, during treatment and during follow-up. A close collaboration and sharing of expertise between pediatric oncologists and nutrition specialists, combined with careful and participatory sharing of the feeding experience with the family and the child (after age 6 years), is strongly required.
