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.

Comparison of malnutrition and malnutrition screening tools in pediatric oncology patients: A cross-sectional study

OBJECTIVES

The aim of this study was to determine the prevalence of malnutrition, to compare nutritional evaluation tools, and to highlight the importance of nutritional status in pediatric oncology patients.

METHODS

This study evaluated the nutritional status, based on height, weight, and midupper arm circumference, of 170 patients ages 5 months to 18 years who were hospitalized at the Ege University Hospital Pediatric Oncology Clinic. The prevalence of malnutrition was determined using the malnutrition screening tools, STRONGkids (SK) and Pediatric Yorkhill Malnutrition Score (PYMS). Correlations, sensitivity, specificity, and the positive and negative predictive values between the screening tools were calculated.

RESULTS

In all, 68.2% of the patients were diagnosed with a solid tumor. According to SK, 59.4% had a moderate risk of malnutrition, and 40.6% had a high risk. According to PYMS, 30.6% of patients had a low to moderate risk of malnutrition, and 69.4% had a high risk of malnutrition. Minimal agreement was noted between SK and PYMS (Kappa value: 0.40 and 0.18, respectively). The sensitivity of PYMS was higher than that of SK (92.68 and 78.05, respectively). In total, 22.9% of the patients had a body mass index of <5%, and 21.2% had a midupper arm circumference of <5.

CONCLUSIONS

The present findings show that, in general, pediatric oncology patients have a high risk of malnutrition. Although SK and PYMS do not differ significantly, PYMS has higher sensitivity for detecting malnutrition. The nutritional status of pediatric oncology patients should be monitored using appropriate screening techniques throughout their treatment.

Eating and feeding problems in children with cancer: Prevalence, related factors, and consequences

BACKGROUND & AIMS

During treatment for cancer, children experience many side effects such as lack of appetite, nausea, and vomiting. As a result, ensuring adequate intake puts pressure on both the child and the parent. This study aims to determine the prevalence, causes and consequences of eating and feeding problems in children treated for cancer.

METHODS

Parents of 85 children with cancer completed the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) and symptoms, BMI, energy intake, feeding style, and parental distress were measured at 0, 3, 6 and 12 months after diagnosis.

RESULTS

Parent-reports revealed that almost a quarter of the children experienced eating disorder: 15.7% experienced problems related to diminished intake and 8.6% related to excessive intake. Prevalence of feeding disorders related to parents' behavior was 21.1%. In children <8 years prevalence of eating and feeding disorders was significantly higher: 31% and 36% for child and parent behavior respectively. Younger age, poor pre-illness eating behavior, increase in symptoms and a demanding feeding style were associated with more eating problems. Excessive eating resulted in higher energy intake, however, no association was found between eating problems and nutritional status. Food refusal resulted in more parental distress.

CONCLUSIONS

Especially younger children with cancer are at risk for eating and feeding problems. In addition, poor pre-illness eating behavior, symptoms and a demanding feeding style aggravate eating problems. Therefore, interventions should focus at diminishing side effects of treatment and instructing parents to be less demanding regarding their child's eating behavior.

Dietary intake and diet quality in children receiving treatment for cancer

This narrative synthesis aims to examine the dietary intake, diet quality, and dietary preferences of pediatric cancer patients during cancer treatment. Thirteen studies were eligible for review. Studies mostly investigated nutrient intake, with 7 reporting on children's food intake. There was consensus among studies, which reported suboptimal fruit and vegetable intake and a preference for savory, carbohydrate-based foods. Results suggest that pediatric cancer patients consume a limited variety of foods, with a high intake of noncore foods. Future research should aim to examine dietary food data against dietary guidelines to assess adequacy and variety within core food groups.

Percutaneous Endoscopic Gastrostomy in Children with Malignant Disease

The objective of the study was to assess both the possible complications of percutanous endoscopic gastrostomy (PEG) in pediatric cancer patients and its effect on weight development. The medical records of 18 children with a median age of 2.5 years (range, 0.5–14.2 years) were reviewed. The diagnoses were leukemia, central nervous system tumors, solid tumors, and lymphoma. The indications for PEG were anticipated therapy-related nutritional problems and inadequate food intake, weight loss, swallowing problems in relation to paresis of the pharynx, and relapse of the disease. Ten children received a PEG at treatment start, and eight children received it at a median time of 3.4 months (range, 0.9–27.4 months) after treatment start. The median duration of having a PEG in place was 12.3 months (range, 1.2–24.0 months). At admission the median weight for age expressed as standard deviation (SD) was −0.11 (range, −2.78–2.68). There was a significant ( p = .005) decrease in the median SD from admission until PEG installation. There was also a significant increase in the median SD from the start of PEG use until 1 ( p = .04) and 2 ( p = .039) months after start. The most common complications were episodes of inflammation of the PEG site, which were successfully treated with topically or orally administered antibiotics, and episodes of infection, which required intravenously administered antibiotics. Taking into consideration the medical condition of the children in the study group and the considerable length of time with a PEG in place, we believe that nutrition via PEG in children with cancer has several advantages and is rarely associated with other than minor complications.

Altered food intake and taste perception in children with cancer after start of chemotherapy: perspectives of children, parents and nurses

GOALS OF WORK

The purpose of this study was to better understand various variables related to food intake and eating problems in children with cancer during their chemotherapy.

PATIENTS AND METHODS

Twenty-two consecutively admitted children, diagnosed with cancer and undergoing chemotherapy, participated in this study. Twenty-one of them, their parents and attending nurses participated in semi-structured interviews. Ten of the children underwent a taste acuity test, and recognition thresholds for the four basic tastes were determined.

MAIN RESULTS

The shared view of both children and parents was that altered taste was the predominant cause of the eating problems. In contrast, the nurses perceived that nausea was the most important cause of the children's eating problems. In addition, psychological aspects such as learned food aversions and negative attitudes towards hospital food were regarded as important by children, parents and nurses. The taste test showed that the patients had higher thresholds for bitter taste and made more taste recognition errors compared to controls.

CONCLUSIONS

Changes seem to exist both in the primary gustatory sense as well as in food perception in paediatric cancer patients undergoing chemotherapy. Single solutions, such as efforts to serve "tasty food", do not suffice alone. A more effective solution may be to combine different strategies and combinations of oral, enteral and parenteral nutrition should be considered to prevent malnutrition.
