Genome-wide study identifies novel genes associated with bone toxicities in children with acute lymphoblastic leukaemia. Br J Haematol 2024. [PMID: 39143423 DOI: 10.1111/bjh.19696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Accepted: 07/27/2024] [Indexed: 08/16/2024]
Abstract
Bone toxicities are common among paediatric patients treated for acute lymphoblastic leukaemia (ALL) with potentially major negative impact on patients' quality of life. To identify the underlying genetic contributors, we conducted a genome-wide association study (GWAS) and a transcriptome-wide association study (TWAS) in 260 patients of European-descent from the DFCI 05-001 ALL trial, with validation in 101 patients of European-descent from the DFCI 11-001 ALL trial. We identified a significant association between rs844882 on chromosome 20 and bone toxicities in the DFCI 05-001 trial (p = 1.7 × 10-8). In DFCI 11-001 trial, we observed a consistent trend of this variant with fracture. The variant was an eQTL for two nearby genes, CD93 and THBD. In TWAS, genetically predicted ACAD9 expression was associated with an increased risk of bone toxicities, which was confirmed by meta-analysis of the two cohorts (meta-p = 2.4 × 10-6). In addition, a polygenic risk score of heel quantitative ultrasound speed of sound was associated with fracture risk in both cohorts (meta-p = 2.3 × 10-3). Our findings highlight the genetic influence on treatment-related bone toxicities in this patient population. The genes we identified in our study provide new biological insights into the development of bone adverse events related to ALL treatment.

Abstract
The therapeutic approach to Wilms tumor (WT) is multidisciplinary and leads to significant patient impairment, increasing the risk of nutritional compromise and malnutrition. Children with cancer are vulnerable to sarcopenia which has been recognized as a negative impact of anticancer therapy. Recent studies have highlighted the reduction in the total psoas muscle area (TPMA) to be associated with a poor prognosis in many pediatric diseases, including cancer. This study aims to evaluate changes in the TPMA compartment during the treatment of children with WT. An observational, longitudinal, and retrospective study was undertaken in a single institution evaluating children (1 to 14 y, n=38) with WT between 2014 and 2020. TPMA was assessed by the analysis of previously collected, electronically stored computed tomography images of the abdomen obtained at 3 time points: diagnosis, preoperatively, and 1 year after surgery. For all patients, TPMA/age were calculated with a specific online calculator. Our data show a high incidence of sarcopenia (55.3%) at diagnosis which increased after 4 to 6 weeks of neoadjuvant chemotherapy (73.7%) and remained high (78.9%) 1 year after the surgical procedure. Using TPMA/age Z-score curves we have found significant and rapid muscle loss in children with WT, with little or no recovery in the study period.

Abstract
Acute leukemia commonly occurs in young children with peak incidence at the age of 2-5 years. However, the etiology is still unclear and many preventable risk factors still deserve to be reviewed. The focus of this systematic review and meta-analysis is to summarize the evidence concerning early life nourishment (breastfeeding, early life diet), neonatal vitamin K administration and the risk of acute leukemia. All epidemiological studies published up to June 2023 and assessing diet-related risk factors for childhood acute leukemia were identified in two electronic databases (PubMed and Web of Science), with no limits on publication year or language. A total of 38 studies (37 case-control studies and 1 study with pooled analysis) were included. The published risk estimates were combined into a meta-analysis using the Generic Inverse Variance method. The current evidence shows that breastfeeding (yes vs. no) has a protective effect against acute lymphoblastic leukemia (odds ratio = 0.85; 95% CI, 0.76-0.94). Evidence related to the role of other studied factors (foods and supplements) is inconclusive. Further research into the potential role of diet in early life and the risk of acute leukemia is needed to develop prevention strategies at population level.

Improving the Quality of the Delivery of Nutritional Care Among Children Undergoing Treatment for Cancer in a Low- and Middle-Income Country. JCO Glob Oncol 2023; 9:e2300074. [PMID: 37384860 PMCID: PMC10497261 DOI: 10.1200/go.23.00074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/01/2023] [Accepted: 05/19/2023] [Indexed: 07/01/2023] Open
Abstract
PURPOSE International twinning programs have been well-established between institutions in childhood cancer and have led to pediatric cancer units in low- and middle-income countries (LMICs) adopting multidisciplinary forms of care. To advance nutritional care in LMICs, the International Initiative for Pediatrics and Nutrition (IIPAN) provided the structural framework and personnel for the delivery of nutritional care. We describe the impact of a newly established nutrition program on the delivery of nutritional care and nutrition-related clinical outcomes in children and adolescents undergoing treatment for cancer in Nicaragua and Honduras. METHODS A prospective cohort (N = 126) collected clinical data over a 2-year period. Collection of IIPAN's nutritional services received during treatment and clinical data were abstracted from medical charts and registered in Research Electronic Data Capture (REDCap) database. Chi-square, ANOVA, and generalized linear mixed models were used; P < .05 was considered statistically significant. RESULTS Nutritional assessments led to a higher number of patients receiving recommended standard of care. Children classified as underweight during treatment presented higher number of infections and toxicities, length of hospital stay, and days of treatment delays during treatment. Overall, from the start to end of treatment, 32.5% of patients improved nutritional status, 35.7% maintained it, and 17.5% worsened. On the basis of metrics, the cost per consultation was less than 4.80 US dollars (USD; Honduras) and 1.60 USD (Nicaragua). CONCLUSION Integration and equitable access of the nutritional care process for all patients needs to be recognized as a component of the basic management in pediatric oncology care. IIPAN's nutritional program demonstrates that nutritional care is economical and feasible in a limited resource setting.

Abstract
Many South African children live in poverty and food insecurity; therefore, malnutrition within the context of childhood cancer should be examined. Parents/caregivers completed the Poverty-Assessment Tool (divided into poverty risk groups) and the Household Hunger Scale questionnaire in five pediatric oncology units. Height, weight, and mid-upper arm circumference assessments classified malnutrition. Regression analysis evaluated the association of poverty and food insecurity with nutritional status, abandonment of treatment, and one-year overall survival (OS). Nearly a third (27.8%) of 320 patients had a high poverty risk, associated significantly with stunting (p = 0.009), food insecurity (p < 0.001) and residential province (p < 0.001) (multinomial regression). Stunting was independently and significantly associated with one-year OS on univariate analysis. The hunger scale was significant predictor of OS, as patients living with hunger at home had an increased odds ratio for treatment abandonment (OR 4.5; 95% CI 1.0; 19.4; p = 0.045) and hazard for death (HR 3.2; 95% CI 1.02, 9.9; p = 0.046) compared to those with food security. Evaluating sociodemographic factors such as poverty and food insecurity at diagnosis is essential among South African children to identify at-risk children and implement adequate nutritional support during cancer treatment.

Abstract
Many studies have investigated the etiology of acute leukemia, one of the most common types of cancer in children; however, there is a lack of clarity regarding preventable risk factors. This systematic review and meta-analysis aimed to summarize the current evidence regarding the role of maternal dietary factors in the development of childhood leukemia. All epidemiological studies published until July 2022 that evaluated maternal dietary risk factors for childhood acute leukemia were identified in two electronic databases (PubMed and Web of Science) without limits of publication year or language. A total of 38 studies (1 prospective cohort study, 34 case-control studies and 3 studies with pooled analysis) were included. The published risk estimates were combined into a meta-analysis, using the Generic Inverse Variance method. The maternal consumption of fruits (two or more daily servings vs. less) was inversely associated with acute lymphoblastic leukemia (odds ratio = 0.71; 95% CI, 0.59-0.86), whereas maternal coffee intake (higher than two cups per day vs. no consumption) was associated with an increased risk of acute lymphoblastic leukemia (odds ratio = 1.45; 95% CI, 1.12-1.89). Despite these findings, more high-quality research from cohort studies and the identification of causal factors are needed to develop evidence-based and cost-effective prevention strategies applicable at the population level.

Abstract
Education of the pediatric oncology workforce is an important pillar of the World Health Organization CureAll technical package. This is not only limited to healthcare workers, but all stakeholders in the childhood cancer management process. It includes governmental structures, academic institutions, parents and communities. This review evaluated the current educational and advocacy training resources available to the childhood cancer community, the contribution of SIOP Africa in the continental educational needs and evaluated future needs to improve the management of pediatric malignancies in reaching the Global Initiative for Childhood Cancer goals. Childhood cancer, unlike adult cancers, has not been prioritized in African cancer control plans nor the teaching and advocacy surrounding pediatric oncology. The availability of formal training programs for pediatric oncologists, pediatric surgeons and radiotherapy specialists are limited to particular countries. In pharmacy and nutritional services, the exposure to pediatric oncology is limited while training in advocacy doesn't exist. Many nonacademic stakeholders are creating the opportunities in Africa to gain experience and train in these various fields, but formal training programs should still be advocated for. LEARNING POINTSThe African continent has various resources to increase the capacity of childhood cancer care stakeholders to increase their knowledge.African pediatric oncology teams rely on a multitude of international sources for training while developing their own.There is a greater need for formal, standardized cancer training especially for pediatric surgeons, radio-oncologists and nurses.Greater inclusion of pathologists, pediatric oncology pharmacists and dieticians into multidisciplinary care and childhood cancer training should be facilitated and resourced.Successful advocacy programs and tool kits exist in parts of Africa, but the training in advocacy is still underdeveloped.

Abstract
This study investigates the prevalence of vitamin and iron deficiencies at cancer diagnosis. Newly diagnosed children between October 2018 and December 2020 at two South African pediatric oncology units (POUs) were assessed for nutritional and micronutrient status (Vit A, Vit B12, Vit D, folate, and iron). A structured interview with caregivers provided information regarding hunger and poverty risks. There were 261 patients enrolled with a median age of 5.5 years and a male-to-female ratio of 1:0.8. Nearly half had iron deficiency (47.6%), while a third had either Vit A (30.6%), Vit D (32.6%), or folate (29.7%) deficiencies. Significant associations existed between moderate acute malnutrition (MAM) and low levels of Vit A (48.4%; p = .005), Vit B12 (29.6%; p < .001), and folate (47.3%; p = .003), while Vit D deficiency was associated with wasting (63.6%) (p < .001). Males had significantly lower Vit D levels (respectively, 40.9%; p = .004). Folate deficiency was significantly associated with patients born at full term (33.5%; p = .017), age older than five years (39.8%; p = .002), residing in provinces Mpumalanga (40.9%) and Gauteng (31.5%) (P = .032); as well as having food insecurity (46.3%; p < .001), or hematological malignancies (41.3%; p = .004). This study documents the high prevalence of Vit A, Vit D, Vit B12, folate, and iron deficiency in South African pediatric cancer patients, demonstrating the need to include micronutrient assessment at diagnosis to ensure optimal nutritional support for macro-and micronutrients.

Abstract
Among drug-induced adverse events, pancreatitis is life-threatening and results in substantial morbidity. A prototype example is the pancreatitis caused by asparaginase, a crucial drug used to treat acute lymphoblastic leukemia (ALL). Here, we used a systems approach to identify the factors affecting asparaginase-associated pancreatitis (AAP). Connectivity Map analysis of the transcriptomic data showed that asparaginase-induced gene signatures were potentially reversed by retinoids (vitamin A and its analogs). Analysis of a large electronic health record database (TriNetX) and the U.S. Federal Drug Administration Adverse Events Reporting System demonstrated a reduction in AAP risk with concomitant exposure to vitamin A. Furthermore, we performed a global metabolomic screening of plasma samples from 24 individuals with ALL who developed pancreatitis (cases) and 26 individuals with ALL who did not develop pancreatitis (controls), before and after a single exposure to asparaginase. Screening from this discovery cohort revealed that plasma carotenoids were lower in the cases than in controls. This finding was validated in a larger external cohort. A 30-day dietary recall showed that the cases received less dietary vitamin A than the controls did. In mice, asparaginase administration alone was sufficient to reduce circulating and hepatic retinol. Based on these data, we propose that circulating retinoids protect against pancreatic inflammation and that asparaginase reduces circulating retinoids. Moreover, we show that AAP is more likely to develop with reduced dietary vitamin A intake. The systems approach taken for AAP provides an impetus to examine the role of dietary vitamin A supplementation in preventing or treating AAP.

Abstract
Childhood acute lymphoblastic leukemia (ALL) is the most common childhood cancer with survival exceeding 90% for standard-risk groups. A debilitating side-effect of treatment is the development of overweight/obesity (OW/OB), which develops in approximately 40% of children by the end of treatment. The microbiome has been associated with the development of OW/OB. We examined fluctuations in the microbiome with the development of OW/OB during the first six months of treatment at diagnosis, and two subsequent timepoints (N = 62). Shotgun metagenomic sequencing was performed on Illumina Nextseq system, and taxa and functional pathways were extracted from sequences using kraken2 and humann2, respectively. An association of increased presence of several species (e.g., Klebsiella pneumoniae, Escherichia coli) was observed in children with OW/OB, while lean-promoting species (Veillonella, Haemophilus, and Akkermansia) were increased in children who maintained a normal weight. Pathway analysis revealed purine nucleotide biosynthesis, sugar nucleotide biosynthesis, and enzyme cofactor biosynthesis were positively correlated with Bacteroides spp. among children with OW/OB. We identified several taxa and functional pathways that may confer increased risk for the development of OW/OB. The associations observed in this pilot are preliminary and warrant further research in the microbiome and the development of OW/OB in childhood ALL.

Abstract
Arm anthropometry is a more sensitive measure of nutritional status than body mass index for age (BMI) in children with cancer, but the added utility of serum albumin remains uncertain. Concordance was determined among four forms of classifying nutritional status in a cohort of undernourished children with cancer: method 1: BMI-for-age Z score; method 2: method 1 + mid-upper arm circumference (MUAC) percentile; method 3: method 2 + triceps skinfold thickness (TSFT) percentile; and method 4: method 3 + serum albumin. Concordance was highest between methods 2 and 3, followed closely by 3 and 4, indicating that addition of arm anthropometry, but not serum albumin, to BMI increased the sensitivity of baseline nutritional assessment.

Abstract
INTRODUCTION There is lack of diagnostic and treatment resources with variable access to childhood cancer treatment in low- and middle-income countries (LMIC), which may lead to subsequent poor survival. The primary aim of this study was to determine the prevalence and types of traditional and complementary medicine (T&CM) used in Cameroon. Secondarily, we explored determinants of T&CM use, associated costs, perceived benefits and harm, and disclosure of T&CM use to medical team. METHODS A prospective, cross-sectional survey among parents and carers of children younger than 15 years of age who had a cancer diagnosis and received cancer treatment at three Baptist Mission hospitals between November 2017 and February 2019. RESULTS Eighty participants completed the survey. Median patient age was 8.1 years (IQR4.1-11.1). There was significant availability (90%) and use (67.5%) of T&CM, whereas 24% thought T&CM would be good for cancer treatment. Common T&CM remedies included herbs and other plant remedies or teas taken by mouth, prayer for healing purposes and skin cutting. Living more than five hours away from the treatment center (P = 0.030), anticipated costs (0.028), and a habit of consulting a traditional healer when sick (P = 0.006) were associated with the use of T&CM. T&CM was mostly paid for in cash (53.7%) or provided free of charge (29.6%). Of importance was the fact that nearly half (44%) did not want to disclose the use of TM to their doctor. CONCLUSION Pediatric oncology patients used T&CM before and during treatment but were unlikely to disclose its use to the child's health care team.

Abstract
BACKGROUND Changesin nutritional status can constitute a risk factor for reduced tolerance and effectiveness of antineoplastic treatment. Knowledge of the nutritional status of pediatric patients is important for implementing interventions to improve outcomes. We aimed to evaluate nutritional status at diagnosis and throughout therapy in pediatric patients with solid tumors. OBJECTIVES To study the prevalence of malnutrition at diagnosis, compare different assessment tools, and examine longitudinal changes in nutritional status during the treatment of pediatric patients with solid tumors in a Brazilian institution. METHODS This prospective single-center study enrolled patients with solid tumors (age <19 years) from June 2017 to May 2018. Nutritional evaluations were performed at diagnosis and after 3 and 6 months of treatment. z-Scores for height for age (H/A) and body mass index for age (BMI/A) were calculated using the Anthro/AnthroPlus software and mid-upper arm circumference (MUAC) percentile was used for nutritional classification. RESULTS The prevalence of nutritional status at diagnosis was 29.3% malnourished, 49.5% adequate, and 21.2% overweight/obese. Nutritional status improved during the first 3 months of treatment, with a reduction in the proportion of malnourished patients and an increased number of patients with adequate nutritional status. CONCLUSIONS The two combined indices, BMI/A and MUAC, facilitated the diagnosis of a greater number of patients with solid tumors who had nutritional alterations. A high prevalence of malnutrition was present at diagnosis. Nutritional status improved in the first 3 months of treatment and could be related to the multidisciplinary institutional approach following the diagnosis.

Abstract
OBJECTIVES Malnutrition is common in developing countries and is not restricted to young children. It has been suggested that measuring mid-upper arm circumference (MUAC) is an easy, accurate, and low-cost method of identifying malnutrition in the early stages. The aims of this study were to construct age- and sex-specific MUAC reference centiles, and to define and validate cutoffs for assessment of under- and overnutrition in Indian children 5 to 17 y of age. METHODS This was a cross-sectional, multicentric, observational study conducted in seven schools in seven states from June 2018 to November 2019. The study included 6680 healthy 5- to17-y-old children. MUAC was measured using non-stretch tapes (UNICEF). Sex-specific MUAC percentiles were computed for age and height. Cutoffs for MUAC z-scores for thinness and overnutrition were defined and validated for healthy school children (n = 726) and children with cancer (n = 500). RESULTS Reference centiles for MUAC for age (and height) for boys and girls are presented. Cutoffs defined for thinness and for obesity were -0.7 and +1.5 z-score, respectively (corresponding to 25th and 95th percentiles of the MUAC for age/height). For ease of use, rounded cutoffs for thinness were 16 and 18.5 cm from 5 to 9 and 10 to 14 y of age, respectively, in both sexes, and a cutoff of 22 cm in boys and 20 cm in girl from 15 to 17 y of age. For obesity, 20 and 25.5 cm from 5 to 9 and 10 to 14 y of age, respectively, in both girls and boys and a rounded cutoff of 29 cm in boys and 27 cm in girls from 15 to17 y are proposed. CONCLUSIONS We presented MUAC percentiles and cutoffs for screening for thinness and overnutrition in Indian children from 5 to 17 y of age. These data may also be used in children with cancer and other chronic disorders with growth failure.

Walters M, Mowbray C, Jubelirer T, Jacobs S, Kelly KM, Smith K, Yao Y, Jin Z, Ladas EJ. A bilingual dietary intervention early in treatment is feasible and prevents weight gain in childhood acute lymphoblastic leukemia. Pediatr Blood Cancer 2021; 68:e28910. [PMID: 33590674 DOI: 10.1002/pbc.28910] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 01/04/2021] [Accepted: 01/05/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND Childhood acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. The onset of obesity during childhood ALL has been well established and is associated with inferior survival rates and increased treatment-related toxicities. This pilot study sought to determine if a dietary intervention is feasible and minimizes weight gain during the initial phases of treatment for ALL. METHODS Participants were recruited from four institutions, fluent in English or Spanish, between 5 and 21 years old, and enrolled within 3 days of starting induction therapy. Participants were counseled for 6 months to follow a low glycemic diet. Dietary and anthropometric data were collected at diagnosis, end of induction, and end of month 6 (NCT03157323). RESULTS Twenty-three of 28 participants (82.1%) were evaluable and included in the analysis. Dietary changes targeted by the nutrition intervention were successful; sugar intake declined (P = .003), whereas vegetable intake increased (P = .033). The majority of participants were able to adhere to the dietary principles prescribed: ≥70.0% reduced glycemic load and ≥60.0% increased fiber intake and decreased sugar intake. Importantly, we did not observe an increase in body mass index z-score during induction or over the 6-month intervention period. Most families found the nutrition intervention easy to follow (60%) and affordable (95%) despite simultaneous initiation of treatment for ALL. CONCLUSIONS A 6-month nutrition intervention initiated during the initial phase of treatment for childhood ALL is feasible and may prevent weight gain. Our preliminary findings need to be confirmed in a larger clinical trial.

Abstract
Body composition is increasingly recognized as an important factor in cancer outcomes. Use of computed tomography (CT) in cancer care provides the opportunity to accurately quantify whole‐body lean and adipose tissues from images at the third lumbar spine. We sought to substantiate the use of routinely captured, single‐slice chest CT images at the thoracic level for evaluation of skeletal muscle, residual lean tissue, and adiposity among pediatric solid tumor patients. We performed a retrospective analysis among children who underwent treatment for a solid tumor at Columbia University Irving Medical Center. Skeletal muscle (SM), residual lean tissue (RLT), and adipose tissue cross‐sectional areas (cm2) were analyzed at diagnosis and at first follow‐up for disease evaluation (6–14 weeks). Imaging analysis was performed utilizing slice‐O‐matic image analysis software. Of the 57 patients identified, 39 had chest CT imaging that included intervertebral level T12‐L1, and 22 also had concurrent imaging at L3. Correlation coefficients between body composition variables at T12‐L1 and L3 were strong (r = 0.93–0.98). Paired t‐test showed a significant decrease in SM (−4.2 ± 8.12, p = 0.003) and RLT (−10.7 ± 28.5, p = 0.025) as well as a trend toward a significant increase in visceral adipose tissue (3.10 ± 9.65, p = 0.052). Univariable analysis demonstrated a significant association between increasing age and increased SM loss (β = −0.496 with SE = 0.194, p = 0.011), and a lack of association between body mass index and body composition changes. We provide the first line of evidence that single‐slice images from routinely obtained chest CT scans provide a simple, readily available mechanism for assessing body composition in pediatric solid tumor patients. Adverse body composition changes were observed, particularly among adolescents and young adults. Precis: Changes in body composition can be detected via routine CT images in pediatric patients undergoing treatment for solid tumors.

Abstract
Sarcopenia (severe skeletal muscle wasting) and sarcopenic obesity (skeletal muscle wasting in the setting of excess fat) have been increasingly recognized as important prognostic indicators in adult oncology. Unfavorable changes in lean and adipose tissue masses manifest early in therapy and are associated with altered chemotherapy metabolism as well as increased treatment-related morbidity and mortality. Existing literature addresses the role of body composition in children with hematologic malignancies; however, data is lacking among solid tumor patients. Advances in imaging techniques for quantification of tissue compartments potentiate further investigation in this highly understudied area of pediatric oncology. The following review presents an in-depth discussion of body composition analysis and its potential role in the care of pediatric solid tumor patients. Integration of body tissue measurement into standard practice has broad clinical implications and may improve quality of life and treatment outcomes in this at-risk population.

Abstract
The human microbiome consists of trillions of microbial cells that interact with one another and the human host to play a clinically significant role in health and disease. Gut microbial changes have been identified in cancer pathogenesis, at disease diagnosis, during therapy, and even long after completion of treatment. Alterations in the gut microbiome have been linked to treatment-related toxicity and potential long-term morbidity and mortality in children with cancer. Such alterations are plausible given immune modulation due to disease as well as exposure to cytotoxic chemotherapy, infections, and antibiotics. The following review presents our current scientific understanding on the role of the gut microbiome in pediatric cancer, identifies gaps in knowledge, and suggests future research goals.

Abstract
PURPOSE The benefits and risks of supplementation with antioxidants during cancer therapy have been a controversial area. Few studies have systematically evaluated dietary intake of antioxidants with toxicity and survival in childhood cancer. We sought to determine the role of dietary intake of antioxidants on rates of infections, mucositis, relapse, and disease-free survival during induction and postinduction phases of therapy among children and adolescents with acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS We enrolled 794 children in a prospective clinical trial for treatment of ALL. Dietary intake was prospectively evaluated by a food frequency questionnaire. The association between dietary intake of antioxidants and treatment-related toxicities and survival were evaluated with the Benjamini-Hochberg false discovery rate (q) and logistic regression and the Kaplan-Meier method, respectively. RESULTS Dietary surveys were available for analysis from 614 (77%), and 561 (71%) participants at diagnosis and at end of induction, respectively. Of 513 participants who completed the dietary surveys at both time points, 120 (23%) and 87 (16%) experienced a bacterial infection and 22 (4%) and 55 (10%) experienced mucositis during the induction or postinduction phases of treatment, respectively. Increased intake of dietary antioxidants was associated with significantly lower rates of infection and mucositis. No association with relapse or disease-free survival was observed. Supplementation was not associated with toxicity, relapse, or survival. CONCLUSION Consumption of antioxidants through dietary intake was associated with reduced rates of infection or mucositis, with no increased risk of relapse or reduced survival. Dietary counseling on a well-balanced diet that includes an array of antioxidants from food sources alone may confer a benefit from infections and mucositis during treatment of childhood ALL.

Abstract
Nutrition therapy is a therapeutic approach to treating medical conditions and symptoms via diet, which can be done by oral, enteral or parenteral routes. It is desirable to include nutritional interventions as a standard of care in pediatric cancer units (PCUs) at all levels of care. The interventions are dependent on available resources and personnel across all clinical settings. Enteral nutrition is easy, inexpensive, uses the gastrointestinal tract, maintains gut mucosal integrity, and allows for individualized nutritional strategies. This narrative review describes enteral nutritional interventions for children undergoing cancer treatment and is aimed at PCUs of all levels of care located in a low- and middle-income country.

Abstract
Traditional and complementary medicine (T&CM) strategies are commonly used by pediatric cancer patients. Nutritional approaches to T&CM include bioactive compounds, supplements, and herbs as well as dietary approaches. Pediatric cancer patients and their families commonly request and use nutritional T&CM strategies. We review the potential risks and benefits of nutritional T&CM use in pediatric cancer care and provide an overview of some commonly used and requested supplements, including probiotics, antioxidants, cannabinoids, vitamins, turmeric, mistletoe, Carica papaya, and others. We also discuss the role of specific diets such as the ketogenic diet, caloric restriction diets, whole-food diets, and immune modulating diets. There is a growing body of evidence to support the use of some T&CM agents for the supportive care of children with cancer. However, further study is needed into these agents and approaches. Open communication with families about T&CM use is critical.

Abstract
PURPOSE The objective of this systematic review was to describe nutrition-related publications on children and adolescents diagnosed with cancer in Brazil. METHODS The methodology followed that of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Medline, LILACS (the Latin American & Caribbean Health Sciences Literature), and Embase were searched in April 2019, and data extraction and rating of methodologic study quality (according to the National Institutes of Health quality score assessment) were performed independently by reviewers. RESULTS Twenty-seven studies met the inclusion criteria, reporting on 3,509 patients from 1994 to 2018. Most of the studies (74%) were of poor quality in methodology and reporting. Different cancer diagnoses were included in 52% of studies, whereas acute leukemia was the exclusive focus in 41%. The majority of the articles (70%) were from institutions in the Southeast Region of Brazil, mainly the state of São Paulo (74%); no publications were from the North Region of the country. Twelve studies addressed nutritional status and body composition, reporting an abundance of malnourished patients in the Brazilian population of children and adolescents with cancer. Six studies on micronutrients pointed to possible deficiencies in this population, with a yet unclear but promising role for supplementation during treatment. CONCLUSION Evidence indicates that there is great interest in the impact of nutrition on childhood cancer treatment and clinical outcomes in Brazil. However, there is a need to focus on high-quality research, particularly with multicentric/national studies. This will help establish research priorities and better planned clinical interventions, adapted to each region of the country.

Abstract
Proper nutritional status during cancer therapy has been recognised as being integral to a variety of health outcome measures, including overall survival, treatment tolerance, and quality of life. The prevalence of malnutrition, defined by WHO as either undernutrition or overnutrition, among children and adolescents with cancer is reported to be as high as 75%. Yet, over the past two decades there have been limited advances in elucidating the underlying pathophysiological drivers of malnutrition in this population. This effect has resulted in a paucity of research aimed at improving nutritional assessment and intervention among this group. This Review presents an in-depth discussion of the role of nutritional status in paediatric cancer care, as well as evolving avenues of investigation that might propel personalised nutrition into a viable reality. Thus, nutritional science might facilitate individualised intervention strategies, and thereby help to optimise clinical outcomes for patients and survivors of childhood cancer.
