Nutritional status in childhood malignancies

Nutritional Support Best Practices in Pediatric Blood and Marrow Transplant Patients: An Integrative Review

Nutrition is vital to the long-term survival of children undergoing blood and marrow transplantation (BMT), but there is no standardization on how to optimize the nutritional status of these patients. A literature search was performed to evaluate nutritional support approaches currently in practice for pediatric patients who are undergoing BMT. CINAHL, Embase, and Cochrane databases were searched for peer-reviewed articles evaluating nutritional interventions for BMT recipients aged 20 or younger. Nine articles published between 2019 and 2023 were found and reviewed. The nutritional support varied between enteral nutrition, parenteral nutrition, a combination of both, and prophylactic feeding tube placement. The post-transplant outcomes identified as associated with alterations in nutritional regimens included length of stay, date of platelet engraftment, incidence of acute graft-versus-host disease, infection rate, and overall survival. The use of any amount of enteral nutrition compared to parenteral alone was beneficial. Complications during BMT can potentially be decreased via prioritizing enteral nutrition over parenteral. The paucity of literature on this topic highlights an unmet need in the field. Future research should focus on ways to optimize the nutritional support of transplant recipients, including increasing the likelihood of enteral feeding tube placement and utilization.

Nutritional Status and Growth Deficit in Children and Adolescents with Cancer at Different Moments of Treatment

BACKGROUND

Nutrition deficits are common in children and adolescents undergoing cancer treatment and can contribute to a worse prognosis. There are scarce studies regarding this context considering different moments of treatment. The aim of this study was to evaluate the association between moment of treatment and nutritional status in children and adolescents with cancer.

METHODS

A retrospective study was performed from January 2013 to December 2015, including data from all clinical records of patients under 18 years old with cancer. Clinical, nutritional support and anthropometric data were collected at four moments of treatment from cancer diagnosis: diagnosis (t₀), 3 mo, (t₁), 6 mo, (t₂) and 1 year (t₃). In addition, nutritional indicators were evaluated. Generalized Estimating Equation models were performed to analyze changes on anthropometric indices throughout four moments of treatment.

RESULTS

The sample comprised 73 patients and frequency of nutritional deficits ranged from 13.0% to 18.6%. All nutritional indicators decreased at t₁, showed a modest recovery at t₂ and a stronger recovery at t₃ (p < 0.001). Growth was also impacted during treatment, mainly on patients under 2 years in the first three months of treatment.

CONCLUSIONS

Moment of treatment was associated with growth deficit and decreased percentiles in development indicators.

Assessment of Nutritional Status and Malnutrition Risk at Diagnosis and Over a 6-Month Treatment Period in Pediatric Oncology Patients With Hematologic Malignancies and Solid Tumors

In total, 74 pediatric oncology patients with hematologic malignancies (n=56) or solid tumors (n=18) and a median age of 78.5 months were included in this prospective study. The aims were to assess malnutrition risks and nutritional status over a 6-month treatment period measured at regular intervals. The rate of patients with high risk for malnutrition at diagnosis was 28.4% by Screening Tool for Risk of Impaired Nutritional Status and Growth tool and 36.5% by Pediatric Yorkhill Malnutrition Score. Body mass index (BMI) z-scores at diagnosis showed 12.3% undernutrition (<-2 SD) and 6.8% overnutrition (>2 SD), which changed to 6.7% and 11.1% at the sixth month, respectively. Malnutrition (BMI<5th age percentile) was detected in 13.7% at diagnosis. Despite an initial deterioration noted in BMI, BMI for age percentile, and z-scores at month 1 in all malignancy subgroups (at month 3 for acute lymphoblastic leukemia), the scores improved later on. There was an increase in weight from baseline in 88.2% of patients over 6 months. This study revealed a decrease in the prevalence of undernutrition and malnutrition over a 6-month treatment period with improved anthropometrics despite an initial deterioration in all malignancy subgroups and even in patients with high risk for malnutrition at baseline screening. Solid tumors and acute lymphoblastic leukemia seem to be associated with higher likelihood of undernutrition and overnutrition, respectively, during treatment.

Effects of pediatric cancer and its treatment on nutritional status: a systematic review

CONTEXT

Malnutrition in pediatric cancer is common worldwide, yet its prevalence and effects on clinical outcomes remain unclear.

OBJECTIVE

The aim of this review was to evaluate primary research reporting the prevalence of malnutrition in pediatric cancer patients and to assess the effects of pediatric cancer and its treatment on nutritional status.

DATA SOURCES

Electronic databases of MEDLINE, CINHAL, and PubMed were searched (January 1990-February 2013).

STUDY SELECTION

Studies of patients aged <18 years who were diagnosed with and treated for cancer and for whom measurements of anthropometry were reported and included. The primary outcome was the prevalence of malnutrition (undernutrition and overnutrition), expressed as body mass index (BMI), in children diagnosed with and treated for cancer.

DATA EXTRACTION

Evidence was appraised critically by employing the Critical Appraisal Skills Program tool, and data was extracted from original articles.

DATA SYNTHESIS

A total of 46 studies were included, most of which were considered to be of low quality on the basis of heterogeneity in both the criteria and the measurements used to define malnutrition. Undernutrition was identified by measuring BMI, weight loss, mid-upper arm circumference, and triceps skinfold thickness, while overnutrition was assessed using BMI. Overall, the prevalence of undernutrition ranged from 0% to 65% and overnutrition from 8% to 78%. Finally, undernutrition in pediatric cancer at diagnosis was associated with poor clinical outcomes in 6 of 9 studies.

CONCLUSION

The possibility of a high prevalence of malnutrition in childhood cancer, indicated by the studies reviewed, highlights the need for high-quality, population-based, longitudinal studies using standard criteria to identify malnutrition.

Malnutrition screening tools for hospitalized children

PURPOSE OF REVIEW

Malnutrition is highly prevalent in hospitalized children and has been associated with relevant clinical outcomes. The scope of this review is to describe the five screening tools and the recent European Society for Parenteral and Enteral Nutrition (ESPEN) research project aimed at establishing agreed, evidence-based criteria for malnutrition and screening tools for its diagnosis in hospitalized children.

RECENT FINDINGS

Five nutrition screening tools have recently been developed to identify the risk of malnutrition in hospitalized children. These tools have been tested to a limited extent by their authors in the original published studies but have not been validated by other independent studies. So far, such screening tools have not been established widely as part of standard pediatric care.

SUMMARY

Although nutrition screening and assessment are recommended by European Society for Parenteral and Enteral Nutrition and the European Society for Pediatric Gastroenterology Hepatology and Nutrition and are often accepted to be required by healthcare facilities, there is no standardized approach to nutritional screening for pediatric inpatients. The near future will provide us with comparative data on the existing tools which may contribute to delineating a standard for useful nutrition screening in pediatrics.

Prevalence of malnutrition in pediatric hospital patients

PURPOSE OF REVIEW

Hospital protein-energy malnutrition and its adverse consequences were already described back in 1980. The purpose of this review is to describe the current prevalence of malnutrition in hospitalized children and to describe current risk groups.

RECENT FINDINGS

Different definitions have been used to describe malnutrition. According to WHO criteria, the SD score with a cutoff of less than -2 should be used to define malnutrition and to compare prevalence data. Using the SD score for weight for height or equivalent criteria, the prevalence of acute malnutrition over the last 10 years in hospitalized children in Germany, France, the UK and the USA varied between 6.1 and 14%, whereas in Turkey up to 32% of patients with malnutrition were reported. Acute malnutrition is still highly prevalent in children with an underlying disease; however, the prevalence rate seems lower in children with cystic fibrosis and malignancies.

SUMMARY

The prevalence of acute malnutrition of children admitted to hospital is still considerably high, but there is a scarcity of data concerning the nutritional status during hospital admission. Screening tools to identify children at risk of developing malnutrition might be helpful.

Parent perceptions of nutritional issues during their child's treatment for cancer

To examine family mealtime interactions, parental concerns about nutrition, and body mass index (BMI) among children with cancer who did not have primary central nervous system involvement. Parents of 95 children receiving treatment for cancer and 95 comparisons completed the About Your Child's Eating-Revised (AYCE-R) measure. Anthropometric data for children with cancer were obtained from medical charts at diagnosis and again when the AYCE-R was administered. No differences in mealtime interactions were found between children with cancer and comparisons, but parents of children with cancer reported greater concern about their child's weight. Anthropometric measures for children with cancer were consistent with national norms. However, children with cancer were somewhat underweight at diagnosis and became heavier over time. Lower BMI was associated with mother and father report of greater resistance from the child at mealtime, father report of his own aversion to family meals, and more severe treatment. The impact of cancer on family mealtime interactions and BMI appeared minimal during treatment. However, further longitudinal research is needed given the risk for late effects, such as growth problems and obesity, among cancer survivors. Families also may benefit from ongoing education to optimize healthy lifestyles among survivors.
