Item Associations of Ferritin and Folate Status With Clinical Outcomes in Childhood Cancer Patients: A Prospective Cohort Study(2025-03-07) Withey, Kalum; Brougham, Mark F. H.; Paciarotti, Ilenia; McKenzie, Jane M.; Wilson, David C.; Revuelta Iniesta, RaquelBackground: Given the limited research on folate and ferritin status in children with cancer undergoing treatment, we investigated the prevalence of abnormalities and their impact on clinical outcomes and treatment complications. Methods: This prospective cohort study enrolled children <18 years diagnosed with cancer between August 2010 and February 2014. Data collection occurred at diagnosis, 3, 6, 9, 12 and 18 months. Clinical outcomes were classified as event‐free survival or events (relapse, death, the development of new metastasis, becoming palliative) and treatment complications. Micronutrient status was assessed through clinical and nutritional analyses. Binary logistic regression, multilevel model analysis explored relationships between micronutrient status and clinical outcomes. Results: Eighty‐two patients (median [interquartile range] 3.9 (1.9–8.8) years, 56% males) were recruited. Excess ferritin (85%) and folate deficiency (25.5%) were prevalent micronutrient abnormalities throughout the study. Decreased ferritin levels reduced the odds of events by 83.9% (odd ratios = 0.161, 95% CI = 1.000–1.002, p = 0.032). Higher ferritin was associated with increased number of treatment‐related complications (B = 7.3E−5, 95% CI = 1.5E−5–0.000, p = 0.013). Folate status showed significant association with body mass index category (χ2 = 9.564, p = 0.008), indicating that overweight and obese patients were more prone to deficiency, and methotrexate (F(2.9); p = 0.06; −2LL (1381)). Haematological malignancies (F(2.8); p = 0.05; −2LL (4244)) and medium and high treatment intensity (F(2.4); p = 0.09; −2LL 4262)) were associated with higher ferritin levels over 18 months. Conclusions: Paediatric cancer patients undergoing treatment exhibit high ferritin and reduced folate levels. Elevated ferritin is linked to increased toxicity and negative clinical outcomes, highlighting the importance of regular assessment and monitoring of both folate and ferritin. Implementing routine monitoring for these biomarkers could help mitigate adverse effects associated with treatment. Large‐scale population‐based studies and clinical trials are now warranted.Item Micronutrient status influences clinical outcomes of paediatric cancer patients during treatment: A prospective cohort study(2021-03-20) Revuelta-Iniesta, Raquel; Gerasimidis, Konstantinos; Paciarotti, Ilenia; McKenzie, Jane; Brougham, Mark F. H.; Wilson, David C.Research reporting plasma micronutrient status and its impact on clinical outcomes in paediatric cancer is scarce. Therefore, we investigated the prevalence of plasma micronutrient abnormalities and their impact on clinical outcomes and treatment complications. A multicentre prospective-cohort study of children aged <18 years diagnosed with cancer was performed between Aug 2010-Jan 2014. Clinical and nutritional data were collected at diagnosis, 3, 6, 9, 12 and 18 months. Micronutrient status was established using in-house laboratory references (vitamin B12, vitamin A and Vitamin E/Ch) and aged adjusted Z-scores (Mg, Se, Zn and Cu) generated from a cohort of healthy Scottish children. Clinical outcomes were classified as "event free survival (EFS)" or "event" (relapse, death, new metastasis or becoming palliative) and treatment complications. Descriptive statistics, logistic regression multilevel analysis were performed. Eighty-two patients [median (IQR) 3.9 (1.9-8.8) years, 56% males] were recruited. Of these, 72 (88%) samples were available, 74% (53/72) patients had micronutrient abnormalities at baseline; deficiencies (25%, 18/72), excesses (19%, 14/72) and a combination of both (29%, 21/72), which continued for 18 months. Vitamin A deficiency (15%, 3/20) and excess (50%, 10/20) were most prevalent at 18 months, whilst vitamin E/Cholesterol and vitamin B12 were mostly within the normal range. Prevalence of Zn deficiency at diagnosis was 36% (16/44 adjusted for CRP), which remained at these levels throughout the study. Reduction in each selenium concentration unit increased the odds of an event by 2% (OR 0.02) and lower Se predicted higher complications at diagnosis [β (-1.2); t (-2.1); 95% CI (-2.9 - (-0.04)); p = 0.04], 3 months [β (-3.9); t (-4.2); 95% CI (-5.57 - (-2.02)); p < 0.001] and 12 months [β (-2.3); t (-2.4); 95% CI (-4.10 - (-0.34)); p = 0.02]. Given the prevalence of micronutrient abnormalities and the negative impact of low selenium on clinical outcome, micronutrient status should be assessed and monitored in paediatric cancer patients. Larger multicentre population based studies and clinical trials are now warranted.Item Nutritional screening and assessment of paediatric cancer patients: A quality improvement project (baseline results)(European Society for Clinical Nutrition and Metabolism, 2020-04-14) Glatt, Dominique; Hughes, Caoimhe; McCarthy, Orlaith; O'Shea, Fiona; Brougham, Mark F. H.; Wilson, David C.; Revuelta-Iniesta, RaquelThe department of Haematology and Oncology at the Royal Hospital for Sick Children (RHSC) in Edinburgh have developed their own nutritional standards specific to paediatric cancer. We aimed to audit the current nutritional practice in anthropometry, nutritional biochemistry and malnutrition screening for paediatric cancer patients against nutritional standards to identify areas for nutritional-practice improvement and progress nutrition-related clinical outcomes. A Clinical audit was conducted >20 weeks between 2015 and 2017 in three data collection locations (inpatient (IP), day-care (DC), or outpatient (OP)) at RHSC. We included patients aged 0-18 years and undergoing treatment for diagnosed malignant childhood cancer (ICCC-3 or Langerhans Cell Histiocytosis). Data were collected by analysing documentation and observing clinical practice for frequency and mode of administration of anthropometry, malnutrition screening, nutritional biochemistry and resulting documentation completion. Results were presented as descriptive statistics and stratified by percentage of standard met (100%, 99-70%, <70%). 185 audited patient records (22 IP, 54 DC and 109 OP) were analysed. The areas which were <70% of the standard were: height and weight documentation for DC; head-circumference for IP; arm anthropometry assessment for all locations; initial PYMS screening and re-screening in IP; malnutrition screening in DC and OP; and initial assessment and re-assessment for serum vitamins D, A, E, B and parathyroid hormone levels. Baseline nutritional practice was successfully established, identifying areas for practice improvement in the RHSC Paediatric Oncology and Haematology Department; this will be implemented in the next step of the audit to optimise patient care.

H.; Wilson, David C.Background and aims Malnutrition (under and overnutrition) in paediatric cancer patients during and after treatment increases short and long-term side-effects; however, factors contributing to malnutrition and patterns of change in nutritional status are still unclear. The aims were to investigate the prevalence of malnutrition, patterns of change in nutritional status and factors contributing to malnutrition in Scottish paediatric cancer patients.
