RESUMO
Most children are surviving acute lymphoblastic leukemia (ALL) today. Yet, the emergence of cardiometabolic comorbidities in this population may impact long-term outcomes including the quality of life and lifespan. Obesity is a major driver of cardiometabolic disorders in the general population, and in ALL patients it is associated with increased risk of hypertension, dysglycemia, and febrile neutropenia when compared with lean ALL patients undergoing therapy. This systematic review aims to assess the current evidence for bariatric interventions to manage obesity in children with ALL. The primary outcome for this systematic review was the change in BMI z-score with implementation of the interventions studied. Literature searches were conducted in several databases. Ten publications addressing the study question were included in this review, and five studies were used in the meta-analysis to assess the impact of the bariatric interventions on obesity. The BMI z-score did not change significantly with the interventions. However, the quality of evidence was low, which precluded the recommendation of their use. In conclusion, prospective, rigorous, adequately powered, and high-quality longitudinal studies are urgently needed to deliver effective lifestyle interventions to children with ALL to treat and prevent obesity. These interventions, if successful, may improves cardiometabolic health outcomes and enhance the quality of life and life expectancy in children with ALL.

BACKGROUND: Meta-iodobenzylguanidine(MIBG) scans are used to detect neuroblastoma metastatic lesions at diagnosis and during posttreatment surveillance. MIBG positivity following induction chemotherapy correlates with poor outcome; however, there are reports of patients with progression-free survival despite MIBG positivity at the end of therapy. The factors distinguishing these survivors from patients who progress or relapse are unclear. FDG-positron-emission tomography (PET) scans can also detect metastatic lesions at diagnosis; however, their role in posttherapy surveillance is less well studied. METHODS: We performed a retrospective analysis of International Neuroblastoma Staging System (INSS) stage 4 patients to identify those with residual MIBG-avid metastatic lesions on end-of-therapy scans without prior progression. Data collected included age, disease sites, histopathology, biomarkers, treatment, imaging studies, and response. RESULTS: Eleven of 265 patients met inclusion criteria. At diagnosis three of 11 patients were classified as intermediate and eight of 11 high risk; nine of 11 had documented marrow involvement. Histologic classification was favorable for four of 10 and MYCN amplification was detected in zero of 11 cases. The median time with persistent MIBG positivity following treatment was 1.5 years. Seven patients had at least one PET scan with low or background activity. Biopsies of three of three MIBG-avid residual lesions showed differentiation. All patients remain alive with no disease progression at a median of 4.0 years since end of therapy. CONCLUSION: Persistently MIBG-avid metastatic lesions in subsets of patients following completion of therapy may not represent active disease that will progress. Further studies are needed to determine whether MYCN status or other biomarkers, and/or PET scans, may help identify patients with residual inactive MIBG lesions who require no further therapy.

INTRODUCTION: The objectives of this study were to describe reports of bother for feeling scared or worried among children with cancer and pediatric hematopoietic stem cell transplant (HSCT) recipients, and to identify factors associated with it. METHODS: We included children receiving cancer treatments who were 8-18 years of age. Three patient types were enrolled: inpatients receiving active cancer treatment, outpatients receiving maintenance acute lymphoblastic leukemia chemotherapy, and outpatients in survivorship. Amount of bother due to feeling scared or worried yesterday or today was self-reported using the Symptom Screening in Pediatrics Tool (SSPedi) on a 0-4 scale. Risk factors were evaluated using logistic regression. RESULTS: Among the 502 children included, 225 (45.0%) reported any degree of bother (score ≥ 1) and 29 (5.8%) reported severe bother (score ≥ 3) for feeling scared or worried. In multiple regression evaluating any bother, boys were less likely to be bothered (odds ratio (OR) 0.60, 95% confidence interval (CI) 0.41-0.87) and inpatients receiving active cancer treatment were more likely to be bothered compared to outpatients in survivorship (OR 3.58, 95% CI 2.00-6.52). The only factor associated with being severely bothered by feeling scared or worried was clinic visit or admission due to fever (OR 4.57, 95% CI 1.24-13.60). DISCUSSION: We found 45% of children receiving cancer treatments reported being bothered by feeling scared or worried. Girls and inpatients receiving active treatment experienced more bother of any degree, while visiting the hospital due to fever was associated with being severely bothered. Future work should identify interventions to prevent or alleviate this symptom.

This clinical practice guideline (CPG) provides clinicians with recommendations regarding chemotherapy emetogenicity classification in pediatric oncology patients. This information is critically important for the appropriate selection of antiemetic prophylaxis. Recommendations are based on a systematic review limited to pediatric patients and a framework for classification when antiemetic prophylaxis is provided. Findings of 87 publications informed the emetogenicity classification of 49 single-agent and 13 combination-agent regimens. Information required for the classification of many chemotherapies commonly administered to pediatric patients is lacking. In the absence of pediatric data, consultation of methodologically sound CPGs aimed at adult oncology patients may be appropriate.

BACKGROUND: Objectives were to describe bothersome fatigue in children with cancer and hematopoietic stem cell (HSCT) recipients and to identify factors associated with severely bothersome fatigue. METHODS: We included children ages 8-18 years treated for cancer or HSCT recipients from three groups: [1] receiving active cancer treatment and admitted to hospital for at least 3 days, [2] attending outpatient clinic for acute lymphoblastic leukemia maintenance therapy, and [3] attending outpatient clinic following treatment completion. Fatigue was measured using the Symptom Screening in Pediatrics Tool (SSPedi); severely bothersome fatigue was defined as a lot or extremely bothersome fatigue (score of 3-4 on 0-4 scale). Factors associated with severely bothersome fatigue were examined using univariate and multiple logistic regression. RESULTS: Of 502 children included, 414 (82.5%) reported some degree of bothersome fatigue (scores 1-4), and 123 (24.5%) reported severely bothersome fatigue (score 3 or 4). In multiple regression analysis, factors significantly associated with severely bothersome fatigue were child age 11-14 and 15-18 years vs 8-10 years (odds ratio (OR) 2.11, 95% confidence interval (CI) 1.21-3.77 and OR 2.96, 95% CI 1.66-5.44), and inpatients receiving cancer treatment vs outpatients who had completed therapy (OR 3.85, 95% CI 2.17-7.27). CONCLUSIONS: We found that 82.5% of children with cancer or HSCT recipients reported bothersome fatigue and 24.5% of children reported severely bothersome fatigue. Risk factors for severely bothersome fatigue were older age and inpatients receiving active cancer treatment. Future work should evaluate systematic symptom screening in clinical practice and apply interventions to reduce fatigue.

BACKGROUND: Objectives were to describe bothersome self-reported changes in taste in pediatric oncology and hematopoietic stem cell (HSCT) patients and to identify patient and treatment-related factors associated with bothersome taste changes. METHODS: We prospectively enrolled children and adolescents with cancer or pediatric HSCT recipients 8-18 years of age from three groups: inpatients receiving cancer treatments; outpatients in maintenance therapy for acute lymphoblastic leukemia (ALL); and outpatients in survivorship. Bothersome changes in taste was self-reported using the Symptom Screening in Pediatrics Tool (SSPedi); nausea was self-reported using the Pediatric Nausea Assessment Tool (PeNAT). RESULTS: Among the 502 children included, 226 (45.0%) reported bothersome taste changes and 48 (9.6%) reported severely bothersome taste changes. In multiple regression, factors independently associated with severely bothersome taste changes were: inpatients receiving cancer treatments vs outpatients in survivorship (odds ratio (OR) 12.28, 95% confidence interval (CI) 2.50-222.27), ALL in maintenance vs outpatients in survivorship (OR 7.43, 95% CI 1.06-147.77), current nausea (OR 1.59, 95% CI 1.04-2.42), vomiting (OR 2.18, 95% CI 1.06-4.38), and first language not English (OR 2.09, 95% CI 0.97-4.28). CONCLUSIONS: We found that 45% of children with cancer and pediatric HSCT recipients reported bothersome changes in taste and these were severely bothersome in 9.6% of children. Inpatients receiving cancer treatment, those experiencing more nausea and vomiting and children whose first language was not English were at greater risk of severely bothersome changes in taste. Future work should evaluate systematic symptom screening in clinical practice and identify interventions focused on addressing bothersome taste changes.

Opportunities for participation in clinical trials are a core component of the care of children with cancer. In Ontario, many pediatric patients live long distances from their cancer center. This paper describes the work that was done in order to allow patients participating in Children's Oncology Group trials to receive care, including research protocol related care, jointly between the tertiary pediatric cancer center and the closer-to-home satellite center. The system is a pragmatic risk-based model, supporting excellence in care while ensuring good conduct of the research in compliance with applicable regulations and guidelines, including ethics oversight.

BACKGROUND: Objectives were to describe the proportion of deaths due to treatment-related mortality (TRM) and to identify risk factors and probable causes of TRM among paediatric cancer deaths in a population-based cohort. METHODS: We included children with cancer ⩽18 years diagnosed and treated in Ontario who died between January 2003 and December 2012. Deaths were identified using a provincial registry, the Pediatric Oncology Group of Ontario Networked Information System. Probable causes of TRM were described. RESULTS: Among the 964 deaths identified, 821 were included. The median age at diagnosis was 6.6 years (range 0-18.8) and 51.8% had at least one relapse. Of the deaths examined, TRM occurred in 217/821 (26.4%) while 604/821 (73.6%) were due to progressive cancer. Deaths from TRM did not change over time. Using multiple regression, younger age, leukaemia diagnosis and absence of relapse were independently positively associated with TRM. The most common probable causes of TRM were respiratory, infection and haemorrhage. CONCLUSIONS: TRM was responsible for 26.4% of deaths in paediatric cancer. Underlying diagnosis, younger age and absence of relapse were associated with TRM and causes of TRM differed by diagnosis group. Future work should evaluate TRM rate and risk factors among newly diagnosed cancer patients.

This update of the 2013 clinical practice guideline provides clinicians with guidance regarding the use of aprepitant and palonosetron for the prevention of acute chemotherapy-induced nausea and vomiting (CINV) in children. The recommendations were based on three systematic reviews. Substantive changes were made to the guideline recommendations including the inclusion of palonosetron to the 5-HT3 antagonists recommended for children receiving highly emetogenic chemotherapy (HEC) and the recommendation of aprepitant for children 6 months of age or older receiving HEC. To optimize CINV control in children, future work must focus on closing critical research gaps.

Little is known about the impact of enrollment on therapeutic clinical trials on adverse event rates. Primary objective was to describe the impact of clinical trial registration on sterile site microbiologically documented infection for children with newly diagnosed acute myeloid leukemia (AML). We conducted a multicenter cohort study that included children aged ≤18 years with de novo AML. Primary outcome was microbiologically documented sterile site infection. Infection rates were compared between those registered and not registered on clinical trials. Five hundred seventy-four children with AML were included of which 198 (34.5%) were registered on a therapeutic clinical trial. Overall, 400 (69.7%) had at least one sterile site microbiologically documented infection. In multiple regression, registration on clinical trials was independently associated with a higher risk of microbiologically documented sterile site infection [adjusted odds ratio (OR) 1.24, 95% confidence interval (CI) 1.01-1.53; p = 0.040] and viridans group streptococcal infection (OR 1.46, 95% CI 1.08-1.98; p = 0.015). Registration on trials was not associated with Gram-negative or invasive fungal infections. Children with newly diagnosed AML enrolled on clinical trials have a higher risk of microbiologically documented sterile site infection. This information may impact on supportive care practices in pediatric AML.

PURPOSE: Fertility preservation options are limited in prepubertal boys with cancer. Worldwide there has been growing interest in testicular tissue cryopreservation as a promising experimental strategy to address future infertility. We measured and compared parent, male cancer survivor and provider willingness to accept the risk of testicular biopsy among prepubertal boys with cancer, and identified reactions to disclosure practices. MATERIALS AND METHODS: We conducted a multicenter study that included 153 parents of prepubertal boys with cancer, 77 male survivors of childhood cancer and 30 oncology providers. The threshold technique was used to measure subject relative willingness to accept risk of testicular biopsy under 4 different aspects of care, ie chance of infertility, complications from biopsy, development of technology to use tissue and tissue storage cost. A total of 47 in-depth interviews were conducted to identify reactions to disclosure practices. RESULTS: A total of 52 survivors (67%), 22 providers (73%) and 110 parents (72%) selected to have testicular biopsy (vs no biopsy). Median minimum infertility risk to make biopsy worthwhile varied from 25% to 30% among the 3 respondent groups. Interviews revealed that some providers would not offer biopsy in cases of greater perceived risk than benefit, that parents preferred having information regardless of risk of infertility and that nondisclosure elicited adverse feelings from some parents. CONCLUSIONS: Parents, survivors and providers were willing to accept risk of prepubertal testicular biopsy. Parental/survivor desire for information and provider decision not to disclose suggest that barriers to information delivery need to be addressed.

This clinical practice guideline provides an approach to the treatment of breakthrough chemotherapy-induced nausea and vomiting (CINV) and the prevention of refractory CINV in children. It was developed by an international, interprofessional panel and is based on systematic literature reviews. Evidence-based interventions for the treatment of breakthrough and prophylaxis of refractory CINV are recommended. Gaps in the evidence used to support the recommendations made in this clinical practice guideline were identified. The contribution of these recommendations to breakthrough and refractory CINV control in children requires prospective evaluation.

PURPOSE: This study aimed to estimate the burden of morbidity, in terms of health-related quality of life (HRQL), in survivors of high-risk neuroblastoma (NBL) after myeloablative chemotherapy followed by autologous hematopoietic stem cell transplant (HSCT). PATIENTS AND METHODS: A national population-based survey was undertaken of survivors of high-risk NBL (N = 99), diagnosed between 1991 and 2010 and treated with HSCT. Parents completed a proxy questionnaire incorporating two HRQL measures, Health Utilities Index (HUI) 2 and 3. Children >12 years of age provided self-assessments. Clinical and demographic data were collected. Independent t-test and one-way analysis of variance were used to assess differences. Comparative data were obtained from previously published work and Statistics Canada's 1998 National Population Health Survey. RESULTS: On a scale of 0 (being dead) to 1.0 (perfect health), mean HRQL utility scores were 0.89 (SD = 0.11) in HUI2 and 0.84 (SD = 0.18) in HUI3. Parents reported morbidity in sensation (52.5%), pain (30.3%), cognition (28.0%), and emotion (24.2%) in HUI2 and in hearing (38.4%), pain (30.3%), cognition (27.3%), and speech (23.2%) in HUI3. HRQL was not significantly different compared to NBL survivors treated without HSCT, but was less than in nontransplanted survivors of acute lymphoblastic leukemia and Wilms tumor, and children in the general population, yet higher than in survivors of brain tumors. CONCLUSIONS: HRQL is compromised in high-risk NBL survivors treated with and without HSCT. A differential effect on hearing reflects additional exposure to platinum-based chemotherapy. These results should inform long-term care and the development of new therapeutic interventions.

Rothia spp. (previously termed Stomatococcus) are normal flora that can cause invasive infections in immunocompromised hosts. The objective of this study was to describe infection characteristics and outcomes of Rothia spp. infections in a large cohort of children with newly diagnosed acute myeloid leukemia (AML). This retrospective chart review is a subanalysis of a larger study in which the aim was to identify factors associated with infection in pediatric patients with AML. Only sterile site infections occurring during chemotherapy were included. Among 578 children with AML, 17 (2.9%) children with at least 1 Rothia spp. infection were identified. All children were neutropenic at the time of infection. Eight (47%) had antecedent colitis or mucositis. Of the 17 infections, 16 were bacteremia and 1 was meningitis. Sepsis occurred in 4 patients, and 1 patient died due to infection. Rothia spp. infections are rare in pediatric AML but can cause significant morbidity and mortality. Future studies should describe trends in incidence and resistance patterns over time.

Vaginal yolk sac tumor is a rare malignant germ-cell tumor occurring most commonly in young girls. The treatment has evolved over the last 3 decades from radical surgery to conservative surgery with chemotherapy to chemotherapy alone. Here we present a case of a 6-month-old girl successfully treated with upfront surgery followed by chemotherapy. We include a literature review of studies on vaginal yolk sac tumor published in the last 30 years. We discuss the role of upfront surgery where possible followed by chemotherapy as a safe alternative to chemotherapy alone for the treatment of this rare malignancy.

BACKGROUND: There is a lack of standardized definition for treatment-related mortality (TRM), which represents an important endpoint in cancer. Our objective was to describe TRM definitions used in studies of children, adolescents and young adults with lymphomas, solid tumors and brain tumors. METHODS: We conducted a systematic review of studies enrolling children, adolescents and young adults with lymphomas, solid tumors and brain tumors in which an anti-cancer intervention was randomized, or all study designs in which TRM was a primary or secondary outcome. We searched Ovid MEDLINE, EMBASE and Evidence-Based Medicine Reviews from 1980 to June 2013. Two reviewers evaluated study eligibility and abstracted data. RESULTS: In total, 67 studies were included and consisted of 62 randomized therapeutic trials and 5 TRM studies. None of the studies (0/67) provided a definition for TRM. Only one randomized trial of rhabdomyosarcoma provided a definition of early death. CONCLUSIONS: We were unable to identify any TRM definitions used in studies of children, adolescents and young adults with lymphomas, solid tumors and brain tumors. Given that a proportion of this patient population may receive intensive treatment, there is an urgent need for consensus-based definitions of TRM for use across clinical trials.

BACKGROUND: Despite the high utilization of blood products by pediatric oncology patients, literature in this population remains scarce. The primary objective of this study was to assess red blood cell (RBC) and platelet (PLT) utilization rates and transfusion thresholds in pediatric oncology patients. The secondary objective was to describe transfusion-related complications including RBC alloantibody development and transfusion reactions. STUDY DESIGN AND METHODS: This epidemiologic cohort study involved pediatric oncology patients at a Canadian academic children's hospital between April 2002 and December 2011. Demographic, clinical, laboratory, and transfusion variables were collected from the Transfusion Registry for Utilization Statistics and Tracking database, a large database that captures more than 50 demographic and clinical variables as well as comprehensive transfusion information and laboratory test results. RESULTS: Of 647 pediatric oncology patients, 430 (66%) received a RBC or PLT transfusion or both during this time period. The median transfusion threshold before a RBC and PLT transfusion was a hemoglobin (Hb) value of 72 g/L (interquartile range [IQR], 68-76 g/L) and a PLT count of 16 × 10(9) /L (IQR, 10 × 10(9) -23 × 10(9) /L), respectively. Ninety-two percent of the issued RBC and PLT products (7507/8154) were cytomegalovirus negative and 90% were irradiated (7299/8154). RBC alloantibody development and transfusion reactions were reported infrequently in 0.5% (2/423) and 4.5% (8/179) of the patients, respectively. CONCLUSION: This study assessed utilization rates, transfusion thresholds, alloantibody development, and transfusion reactions in pediatric oncology patients. The descriptive results from this epidemiologic study provide baseline information to generate hypotheses to be tested in future interventional studies.

This guideline provides an approach to the prevention and treatment of anticipatory chemotherapy-induced nausea and vomiting (CINV) in children. It was developed by an international, inter-professional panel using AGREE II methods and is based on systematic literature reviews. Evidence-based recommendations for pharmacological and non-pharmacological interventions to prevent and treat anticipatory CINV in children receiving antineoplastic agents are provided. Gaps in the evidence used to support the recommendations are identified. The contribution of this guideline to anticipatory CINV control in children requires prospective evaluation.

BACKGROUND: We previously identified published scales for symptom assessment in pediatric cancer patients. The objectives of this study were to identify if any of these scales were suitable for use or adaptation as a self-report symptom screening tool, and if not, to begin the process of creating a new tool. METHODS: A focus group of ten healthcare professionals with expertise in pediatric cancer symptom management and a patient advocate were convened. First, the group identified the optimal properties of a symptom screening tool for pediatric cancer patients. Next, the previously identified symptom assessment scales were evaluated against these properties. As none of the existing scales were adequate for symptom screening, a nominal group technique was used to identify the most important symptoms for inclusion in a new symptom screening tool. RESULTS: Optimal properties of a symptom screening tool included minimal respondent burden, inclusion of 15 items or less, and inclusion of the most burdensome symptoms. None of the previously identified scales were adequate because they lacked content validity and were too long or would be too hard for children to understand. Nominal group technique identified 15 items to be included; an initial draft was developed and named the Symptom Screening in Pediatrics (SSPedi) Tool. CONCLUSIONS: This study identified the lack of an appropriate symptom screening tool for use by pediatric cancer patients. A preliminary version of SSPedi was developed. Subsequent work will ensure that it is understandable by children and evaluate its psychometric properties.

BACKGROUND: The need for new therapies to improve survival and outcomes in pediatric oncology along with the lack of approval and accessible clinical trials has led to "out-of-trial" use of innovative therapies. We conducted a retrospective analysis of requests for innovative anticancer therapy in Canadian pediatric oncology tertiary centers for patients less than 30 years old between 2013 and 2020. METHODS: Innovative therapies were defined as cancer-directed drugs used (a) off-label, (b) unlicensed drugs being used outside the context of a clinical trial, or (c) approved drugs with limited evidence in pediatrics. We excluded cytotoxic chemotherapy, cellular products, and cytokines. RESULTS: We retrieved data on 352 innovative therapy drug requests. Underlying diagnosis was primary CNS tumor 31%; extracranial solid tumor 37%, leukemia/lymphoma 22%, LCH 2%, and plexiform neurofibroma 6%. RAS/MAP kinase pathway inhibitors were the most frequently requested innovative therapies in 28% of all requests followed by multi-targeted tyrosine kinase inhibitors (17%), inhibitors of the PIK3CA-mTOR-AKT pathway (8%), immune checkpoints inhibitors (8%), and antibody drug conjugates (8%). In 112 out of 352 requests, innovative therapies were used in combination with another anticancer agent. 48% of requests were motivated by the presence of an actionable molecular target. Compassionate access accounted for 52% of all requests while public insurance was used in 27%. Mechanisms of funding varied between provinces. CONCLUSION: This real-world data collection illustrates an increasing use of "out-of-trial" innovative therapies in pediatric oncology. This new field of practice warrants further studies to understand the impact on patient trajectory and equity in access to innovative therapies.
