Abstract
Background: Telehealth is an emerging method which may overcome barriers to rehabilitation access for pediatric cancer survivors (aged ≤19 years). This systematic review aimed to examine telehealth-based rehabilitation interventions aimed at preventing, maintaining, or improving disability in pediatric cancer survivors. Methods: We performed systematic searches in Ovid MEDLINE, Ovid EMBASE, Cochrane Library, SCOPUS, Web of Science, and CINAHL Plus between 1994 and 2022. Eligible studies included telehealth-based interventions assessing disability outcomes in pediatric cancers. Results: Database searches identified 4,040 records. Nine unique interventions met the eligibility criteria. Telehealth delivery methods included telephone (n = 6), email (n = 3), mobile health applications (n = 3), social media (n = 3), videoconferencing (n = 2), text messaging (n = 2), active video gaming (n = 2), and websites (n = 2). Interventions focused on physical activity (n = 8) or self-management (n = 1). Outcomes assessing disability varied (n = 6). Three studies reported statistically and clinically significant results. Narrative synthesis of findings was constructed based on the Picker's principles for patient-centered care: (1) values, preferences, and needs; (2) involve family and friends; (3) coordination of care; (4) provide social support; (5) holistic well-being; and (6) information and communication. Conclusions: Telehealth-based rehabilitation interventions for pediatric cancer survivors is an emerging research area with potential to improve disability outcomes. Adequately powered trials with consistency in disability outcome measures are warranted. Additional research is needed to determine the effectiveness and best practices for telehealth-based pediatric cancer rehabilitation.

Abstract
The increasing incidence of childhood cancer in low- and middle-income countries (LMICs) presents significant economic and logistical challenges, affecting health care provision and equitable treatment access. This editorial explores the economic barriers to pediatric oncology care in LMICs, highlighting resource scarcity, socioeconomic inequities, and health care complexities. It emphasizes the need for detailed cost analysis within health systems complicated by inadequate data and variable treatment protocols. Central to the discussion is the "Childhood Cancers Budgeting Rapidly to Incorporate Disadvantaged Groups for Equity (CC-BRIDGE) Tool" from the manuscript by Nancy Bolous et al., who proposed an innovative method to estimate the cost of integrating childhood cancer services into National Cancer Control Plans. This tool aligns with the World Health Organization's Global Initiative for Childhood Cancer to enhance survival rates and advocate for universal health coverage in pediatric oncology. The CC-BRIDGE tool's methodological rigor provides a structured framework for cost analysis. Yet, it is recognized as an initial step requiring further enhancements for comprehensive economic forecasting and societal cost assessments. In conclusion, the editorial highlights the tool's critical role in incorporating childhood cancer care into national strategies in LMICs, contributing to the broader fight against cancer and advocating for comprehensive, equitable health care. It signifies a vital stride toward addressing pediatric oncology's economic challenges and supporting universal health coverage for childhood cancer care.

Abstract
Background Approximately 82% of children with childhood cancer survive more than five years after diagnosis. Living as a cancer survivor elicits a new reality that can include psychosocial impacts. These psychosocial impacts interact collectively, especially regarding reassimilation, and are rarely explored. Objective To explore the psychosocial impacts of surviving childhood cancer and reassimilation back into society in young adult survivors of childhood cancer. Methodology Individual in-depth semi-structured interviews were conducted with childhood cancer survivors and explored psychosocial aspects associated with returning to work, school, and social environments after remission. Interpretive phenomenological analysis was conducted once interviews were manually transcribed. A group interview with survivors was held to discuss the study's findings and interpretation. Results Individual interviews and the group interview revealed three major themes: outlook on reassimilating, outlook on coping, and outlook on cancer. Conclusions This work is a first step to understanding how survivors' personal outlook on coping and healthcare system barriers play influential roles in reassimilation following cancer treatment. Survivors expressed the need for reliable survivorship information and improved communication with healthcare providers regarding what to expect, so they could feel prepared for life post-cancer. These aspects need to be explored more deeply through other qualitative studies.

Abstract
Contexte Environ 82 % des personnes atteintes d’un cancer pendant l’enfance survivent plus de 5 ans après le diagnostic. La survivance transforme leur quotidien et entraîne parfois des difficultés psychosociales. Les séquelles psychosociales – rarement étudiées – sont interreliées, surtout en ce qui concerne la réinsertion aux activités normales. Objectif Examiner les effets psychosociaux de la survie au cancer pédiatrique et la réinsertion sociale des jeunes adultes. Méthodologie Des entrevues individuelles semi-structurées détaillées ont été réalisées auprès de personnes ayant survécu à un cancer pédiatrique afin d’étudier les aspects psychologiques du retour au travail, à l’école et en société après la rémission. Après la transcription manuelle des entrevues, on a procédé à une analyse phénoménologique interprétative. Un groupe de discussion a été organisé pour permettre aux survivants de discuter des résultats de l’étude et de l’interprétation des données. Résultats Les entrevues individuelles et le groupe de discussion ont fait ressortir trois grands thèmes: le regard porté sur la réinsertion, le regard porté sur l’adaptation et le regard porté sur le cancer. Conclusions La présente recherche amorce une démarche visant à comprendre en quoi le regard que portent les survivants sur l’adaptation et les obstacles liés au système de santé influence la réintégration après le cancer. Les survivants ont exprimé le besoin d’obtenir des renseignements fiables sur la survivance au cancer et d’être mieux informés par leurs professionnels de la santé afin de se préparer à la vie après le cancer. Ces aspects devront faire l’objet d’autres études qualitatives détaillées.

Abstract
The basic principle of chemotherapy is to attack cells with fast growth, and cancer cells are targeted by anticancer drugs because they have a faster growth rate than normal cells. High doses of anticancer drugs may cause an irreversible decline in reproductive capacity, and novel approaches for fertility preservation and/or restoration after anticancer treatment are urgently needed. Here, we provide important insights into the recovery of human reproductive cells damaged by chemotherapy. We performed a detailed screening of the cytokines of various human mesenchymal stem cells (hMSCs) to select superior MSCs. Also, we analyzed the Ovarian granulosa cell (OGC)-)-specific functions for restoring function, apoptosis, and mitochondrial functions to confirm the recovery mechanism in damaged OGCs. As a result, we demonstrated that conditioned media (CM) of Umbilical cord mesenchymal stem cells (UC-MSCs) could restore the functions of damaged OGCs primarily through antiapoptotic and antioxidant effects. Furthermore, CM changed the phenotype of damaged OGCs to an energetic status by restoring mitochondrial function and enhanced the mitochondrial metabolic activity decreased by chemotherapy. Finally, we demonstrated that the restoration of mitochondrial function in damaged OGCs was mediated through mitochondrial autophagy (mitophagy). Our findings offer new insights into the potential of stem cell-based therapy for fertility preservation and/or restoration in female cancer patients.

Abstract
BACKGROUND AND AIMS Significantly discrepant survival rates have been documented in single disease childhood cancer cohorts in South Africa; those from higher socioeconomic groups were shown to have a significantly lower risk of death than those from less affluent households. This study aimed to determine the impact of socioeconomic status (SES) on childhood cancer survival using pooled South African data. METHODS Five databases spanning January 2000 to December 2021 were interrogated. SES status was assigned based on a public sector annual household income classification. H0 households (formally unemployed) received free healthcare. H1, H2 and H3 (annual income > United States Dollar [USD] 19,000) households paid for healthcare relative to their income. The Spearman test assessed correlations between SES and disease stage in patients with solid tumours. Hazard ratios were determined using Cox regression modelling. The Kaplan-Meier procedure estimated overall survival (OS). RESULTS A total of 1598 children were eligible for analysis; 1269 had a solid tumour with a negative correlation between SES and stage (Spearman rho = -.178; p < .001). Patients with solid tumours and lower SES showed proportionately higher numbers of stage III and IV disease (p < .01). This proportion decreased with higher SES categories. In the multivariate analyses adjusted for sex, age, tumour type and stage, higher SES was associated with lower mortality risk (p < .001), indicating that the impact of SES on survival was in excess of any effect that could be explained by lower stage disease alone. There was a strong positive correlation between race and SES (Fisher's exact tests, p < .001) across all groups and all SES strata. Five-year OS was 85.3% in children from H3 households versus 46.3% in children from H0 households (p < .001). CONCLUSION SES significantly impacts childhood cancer survival for children with solid tumours in South Africa. SES is a robust surrogate for race in South Africa as a prognostic metric of disease outcome in childhood cancer. Advocacy to increase social support for impoverished patients is essential to achieve equitable improvements in outcomes treated with standardised national treatment guidelines.

Abstract
PURPOSE Structural racism could contribute to racial and ethnic disparities in cancer mortality via its broad effects on housing, economic opportunities, and health care. However, there has been limited focus on incorporating structural racism into simulation models designed to identify practice and policy strategies to support health equity. We reviewed studies evaluating structural racism and cancer mortality disparities to highlight opportunities, challenges, and future directions to capture this broad concept in simulation modeling research. METHODS We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review Extension guidelines. Articles published between 2018 and 2023 were searched including terms related to race, ethnicity, cancer-specific and all-cause mortality, and structural racism. We included studies evaluating the effects of structural racism on racial and ethnic disparities in cancer mortality in the United States. RESULTS A total of 8345 articles were identified, and 183 articles were included. Studies used different measures, data sources, and methods. For example, in 20 studies, racial residential segregation, one component of structural racism, was measured by indices of dissimilarity, concentration at the extremes, redlining, or isolation. Data sources included cancer registries, claims, or institutional data linked to area-level metrics from the US census or historical mortgage data. Segregation was associated with worse survival. Nine studies were location specific, and the segregation measures were developed for Black, Hispanic, and White residents. CONCLUSIONS A range of measures and data sources are available to capture the effects of structural racism. We provide a set of recommendations for best practices for modelers to consider when incorporating the effects of structural racism into simulation models.

Abstract
PURPOSE To identify the factors associated with employment status among mothers of childhood cancer survivors (CCSs). METHODS We conducted a questionnaire survey on mothers of survivors of childhood cancer to clarify practical factors such as care demands, psychological factors such as motivation to work, and support. After calculating descriptive statistics for all variables, binary logistic regression analysis was performed. RESULTS Of 171 mothers, 129 (75.4%) were employed. The most common form of employment was non-regular (n = 83; 48.5%), including part-time, dispatched, and fixed-term workers. At the time of the survey, compared with nonworking mothers, working mothers tended to be more motivated to work and have lower scores for "Long-term Uncertainty" on the Parent Experience of Child Illness Scale. The results of the binary logistic regression analysis indicated that employment was related to higher motivation to work, the continuation of employment during treatment, more outpatient visits, and a higher amount of support. CONCLUSION As employment of CCSs' mothers is associated with psychological factors such as motivation to work and long-term uncertainty, psychological support for CCSs' mothers might promote employment. In addition, because the continuation of employment during treatment affects the employment of mothers after the end of cancer treatment, a leave system that covers the treatment period for childhood cancer needs to be established.

Abstract
IMPORTANCE Prior investigations in social determinants of health (SDoH) in pediatric head and neck cancer (HNC) have only considered a narrow scope of HNCs, SDoH, and geography while lacking inquiry into the interrelational association of SDoH with disparities in clinical pediatric HNC. OBJECTIVES To evaluate the association of SDoH with disparities in HNC among children and adolescents and to assess which specific aspects of SDoH are most associated with disparities in dynamic and regional sociodemographic contexts. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study included data about patients (aged ≤19 years) with pediatric HNC who were diagnosed from 1975 to 2017 from the Surveillance, Epidemiology, and End Results Program (SEER) database. Data were analyzed from October 2021 to October 2022. EXPOSURES Overall social vulnerability and its subcomponent contributions from 15 SDoH variables, grouped into socioeconomic status (SES; poverty, unemployment, income level, and high school diploma status), minority and language status (ML; minoritized racial and ethnic group and proficiency with English), household composition (HH; household members aged ≥65 and ≤17 years, disability status, single-parent status), and housing and transportation (HT; multiunit structure, mobile homes, crowding, no vehicle, group quarters). These were ranked and scored across all US counties. MAIN OUTCOMES AND MEASURES Regression trends were performed in continuous measures of surveillance and survival period and in discrete measures of advanced staging and surgery receipt. RESULTS A total of 37 043 patients (20 729 [55.9%] aged 10-19 years; 18 603 [50.2%] male patients; 22 430 [60.6%] White patients) with 30 different HNCs in SEER had significant relative decreases in the surveillance period, ranging from 23.9% for malignant melanomas (mean [SD] duration, lowest vs highest vulnerability: 170 [128] months to 129 [88] months) to 41.9% for non-Hodgkin lymphomas (mean [SD] duration, lowest vs highest vulnerability: 216 [142] months vs 127 [94] months). SES followed by ML and HT vulnerabilities were associated with these overall trends per relative-difference magnitudes (eg, SES for ependymomas and choroid plexus tumors: mean [SD] duration, lowest vs highest vulnerability: 114 [113] months vs 86 [84] months; P < .001). Differences in mean survival time were observed with increasing social vulnerability, ranging from 11.3% for ependymomas and choroid plexus tumors (mean [SD] survival, lowest vs highest vulnerability: 46 [46] months to 41 [48] months; P = .43) to 61.4% for gliomas not otherwise specified (NOS) (mean [SD] survival, lowest vs highest vulnerability: 44 [84] months to 17 [28] months; P < .001), with ML vulnerability followed by SES, HH, and HT being significantly associated with decreased survival (eg, ML for gliomas NOS: mean [SD] survival, lowest vs highest vulnerability: 42 [84] months vs 19 [35] months; P < .001). Increased odds of advanced staging with non-Hodgkin lymphoma (OR, 1.21; 95% CI, 1.02-1.45) and retinoblastomas (OR, 1.31; 95% CI, 1.14-1.50) and decreased odds of surgery receipt for melanomas (OR, 0.79; 95% CI, 0.69-0.91) and rhabdomyosarcomas (OR, 0.90; 95% CI, 0.83-0.98) were associated with increasing overall social vulnerability. CONCLUSIONS AND RELEVANCE In this cohort study of patients with pediatric HNC, significant decreases in receipt of care and survival time were observed with increasing SDoH vulnerability.

Abstract
PURPOSE This qualitative study aimed to explore Hispanic parents of childhood cancer survivors (CCS) perceptions of facilitators and barriers to their caregiving experience. METHODS We conducted semi-structured phone interviews with 15 Hispanic/Latino parents (English and Spanish). Parents were recruited using a purposive sampling method in a safety-net hospital in Los Angeles County from July-September 2020. Interviews were audio-recorded, professionally transcribed, and analyzed in the language they were conducted. Two coders independently coded interviews following reflexive thematic analysis and elements of grounded theory methodology. RESULTS Most caregivers were mothers caring for leukemia CCS who had finished treatment more than 2 years prior. Caregivers expressed gratitude to social workers for introducing and aiding with the application process for safety-net programs that enabled caregivers to focus on their child's care and well-being. Caregivers revealed the importance of supportive communication with the medical team, particularly after their child's treatment was considered complete. All caregivers found caring for a child with cancer overwhelming, and many described deteriorations in their health and well-being. Financial instability, transportation difficulties, and work disruptions were identified as barriers, resulting in caregiver distress. Caregivers also shared the challenges they experienced navigating the healthcare system, seeking care despite lack of legal residency, and staying afloat despite limited employment opportunities. CONCLUSION Improving navigation to resources and improving relationships with the medical team may reduce the perceived caregiving burden among Hispanic/Latino caregivers throughout their family's cancer journey.

Abstract
Background Several studies have shown significant variation in overall survival rates from childhood cancer between countries, using population-based cancer registry (PBCR) data for all cancers combined and for many individual tumour types among children. Without accurate and comparable data on Tumour stage at diagnosis, it is difficult to define the reasons for these survival differences. This is because measurement systems designed for adult cancers do not apply to children’s cancers and cancer registries often hold limited information on paediatric tumour stage and the data sources used to define it. Aims The BENCHISTA project aims to test the application of the international consensus “Toronto Staging Guidelines” (TG) for paediatric tumours by European and non-European PBCRs for six common paediatric solid tumours so that reliable comparisons of stage at diagnosis and survival rates by stage can be made to understand any differences. A secondary aim is to test the data availability and completeness of collection of several ‘Toronto’ consensus non-stage prognostic factors, treatment types given, occurrence of relapse/progression and cause of death as a descriptive feasibility study. Methods PBCRs will use their permitted data access channels to apply the Toronto staging guidelines to all incident cases of six solid childhood cancers (medulloblastoma, osteosarcoma, Ewings sarcoma, rhabdomyosarcoma, neuroblastoma and Wilms tumour) diagnosed in a consecutive three-year period within 2014–2017 in their population. Each registry will provide a de-identified patient-level dataset including tumour stage at diagnosis, with only the contributing registry holding the information that would be needed to re-identify the patients. Where available to the registry, patient-level data on ‘Toronto’ non-stage prognostic factors, treatments given and clinical outcomes (relapse/progression/cause of death) will be included. More than 60 PBCRs have been involved in defining the patient-level dataset items and intend to participate by contributing their population-level data. Tumour-specific on-line training workshops with clinical experts are available to cancer registry staff to assist them in applying the Toronto staging guidelines in a consistent manner. There is also a project-specific help desk for discussion of difficult cases and promotion of the CanStaging online tools, developed through the International Association of Cancer Registries, to further ensure standardisation of data collection. Country-specific stage distribution and observed survival by stage at diagnosis will be calculated for each tumour type to compare survival between countries or large geographical regions. Discussion This study will be promote and enhance the collection of standardized staging data for childhood cancer by European and non-European population-based cancer registries. Therefore, this project can be seen as a feasibility project of widespread use of Toronto Staging at a population-level by cancer registries, specifying the data sources used and testing how well standardized the processes can be. Variation in tumour stage distribution could be due to real differences, to different diagnostic practices between countries and/or to variability in how cancer registries assign Toronto stage. This work also aims to strengthen working relationships between cancer registries, clinical services and cancer-specific clinical study groups, which is important for improving patient outcomes and stimulating research.

Abstract
IMPORTANCE Adults in disadvantaged socioeconomic positions have elevated risks of a severe course of COVID-19, but it is unclear whether this holds true for children. OBJECTIVE To investigate whether young people from disadvantaged households have a higher risk of COVID-19 hospitalization and whether differences were associated with comorbidities that predispose children to severe courses. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study included all children and adolescents (aged 0-18 years) who were enrolled in a statutory health insurance carrier in Germany during the observation period of January 1, 2020, to July 13, 2021. Logistic regressions were calculated to compare children from households with and without an indication of poverty. Age, sex, days under observation, nationality, and comorbidities (eg, obesity, diabetes) were controlled for to account for explanatory factors. EXPOSURES Disadvantage on the household level was assessed by the employment status of the insurance holder (ie, employed, long- or short-term unemployed, low-wage employment, economically inactive). Socioeconomic characteristics of the area of residence were also assessed. MAIN OUTCOMES AND MEASURES Daily hospital diagnoses of COVID-19 (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes U07.1 and U07.2) were recorded. Comorbidities were assessed using inpatient and outpatient diagnoses contained in the insurance records. RESULTS A total of 688 075 children and adolescents were included, with a mean (SD) age of 8.3 (5.8) years and 333 489 (48.4%) female participants. COVID-19 hospital diagnosis was a rare event (1637 participants [0.2%]). Children whose parents were long-term unemployed were 1.36 (95% CI, 1.22-1.51) times more likely than those with employed parents to be hospitalized. Elevated odds were also found for children whose parents had low-wage employment (odds ratio, 1.29; 95% CI, 1.05-1.58). Those living in low-income areas had 3.02 (95% CI, 1.73-5.28) times higher odds of hospitalization than those in less deprived areas. Comorbidities were associated with hospitalization, but their adjustment did not change main estimates for deprivation. CONCLUSIONS AND RELEVANCE In this cohort study, children who had parents who were unemployed and those who lived in low-income areas were at higher risk of COVID-19 hospitalization. This finding suggests that attention must be paid to children with SARS-CoV-2 from vulnerable families and closer monitoring should be considered. A number of explanatory factors, including comorbidities, were taken into account, but their analysis yielded no clear picture about underlying processes.

Abstract
Racial and ethnic inequities in survival persist for children with acute lymphoblastic leukemia (ALL). In the US, there are strong associations between SES, race/ethnicity, and place of residence. This is evidenced by ethnic enclaves: neighborhoods with high concentrations of ethnic residents, immigrants, and language isolation. The Latinx enclave index (LEI) can be used to investigate how residence in a Latinx enclave is associated with health outcomes. We studied the association between LEI score and minimal residual disease (MRD) in 142 pediatric ALL patients treated at Texas Children's Hospital. LEI score was associated with end-induction MRD positivity (OR per unit increase 1.63, CI 1.12-2.46). There was also a significant trend toward increased odds of MRD positivity among children living in areas with the highest enclave index scores. MRD positivity at end of induction is associated with higher incidence of relapse and lower overall survival among children with ALL; future studies are needed to elucidate the exact causes of these findings and to improve ALL outcomes among children residing within Latinx enclaves.Supplemental data for this article is available online at https://doi.org/10.1080/08880018.2022.2047850.

Abstract
BACKGROUND Socioeconomic differences in survival among children with acute lymphoblastic leukemia (ALL) have been reported in high-income countries and there is an unmet need for strategies to identify vulnerable patient subgroups. Reported differences in survival for children from families with different socioeconomic positions seem to arise when starting maintenance therapy. This could reflect reduced physician's compliance or family adherence to maintenance therapy. METHODS This nationwide cohort study with extensive monitoring of systemic methotrexate (MTX)/6-mercaptopurine (6MP) dosing and metabolite levels, retrospectively investigated 173 Danish children treated according to The Nordic Society for Pediatric Hematology and Oncology ALL2008 protocol from 2008 to 2016. RESULTS Significantly lower prescribed doses of MTX and 6MP were seen in the children in families with short parental education (short vs. medium vs. higher education: mMTX: 13.8, 16.2, and 18.6 mg/m2 /week; p < .01; m6MP: 47.4, 64.9, and 66.1 mg/m2 /day; p = .03) or parents unemployed/not in workforce (unemployed/not in workforce vs. mixed vs. at work: mMTX: 15.0, 19.9, and 17.2 mg/m2 /week; p < .01; m6MP: 54.8, 72.0, and 65.1 mg/m2 /day; p < .01). When assessing family adherence by analyzing MTX and 6MP metabolite levels, including per prescribed dose of MTX and 6MP, we found no significant differences by levels of parental education, affiliation to work market, or income (p > .05 for all comparisons). CONCLUSIONS These results indicate that inferior physician compliance to protocol recommendations on drug dosage rather than families' adherence to therapy may contribute to the association between socioeconomic position and cure rates in childhood ALL, although precise mechanisms remain to be explored.

Abstract
The development and implementation of a multicancer early detection (MCED) test that is effective and affordable has the potential to change cancer care systems around the world. However, careful consideration is needed within the context of different health care settings (both low- and middle-income countries and high-income countries) to roll out an MCED test and promote equity in access.

Abstract
INTRODUCTION Contemporary research about environmental risk factors in an era of global climate change to inform childhood cancer prevention efforts is disjointed. Planetary pediatric providers need to establish a better understanding of how the postnatal environment influences childhood cancer. Authors conducted a scoping review of recent scientific literature with the aim of understanding the environmental risk factors for childhood cancer. METHOD Ovid Medline, CINAHL, and Scopus databases were searched with results limited to the English language with publication years 2010-2021. Two independent reviewers screened 771 abstracts and excluded 659 abstracts and 65 full-text articles on the basis of predefinedcriteria. RESULTS The scoping review identified 47 studies about environmental risk factors for childhood cancer with mixed results and limited consensus in four main categories, including air pollution, chemical exposures, radiation, and residential location. DISCUSSION Research by collaborative international groups of planetary health researchers about environmental risk factors is needed to inform global health policy for childhood cancer prevention efforts.

Abstract
BACKGROUND Although there is evidence of socioeconomic disparities in survival of children diagnosed with central nervous system (CNS) tumors, the impact of neighborhood socioeconomic deprivation on the survival of these malignancies has not been adequately studied. We investigated the association between area deprivation index (ADI), a measure of neighborhood socioeconomic disadvantage, and pediatric CNS tumor survival. METHODS Demographic and clinical characteristics, geocoded addresses at diagnosis, and vital status of pediatric CNS tumor cases (n = 5,477) for the period 1995 to 2017 were obtained from the Texas Cancer Registry. ADI scores were computed for census tracts in Texas using the U.S. Census Bureau 2010 geography. Tracts were classified into quartiles as least, third-most, second-most, and most disadvantaged. Children were mapped to quartiles based on residency at diagnosis. The adjusted hazard ratio (HR) and 95% confidence interval (CI) were calculated. RESULTS The results showed a significantly increased HR for death among children in the most (HR, 1.29; 95% CI, 1.09-1.51), second-most (HR, 1.18; 95% CI, 1.01-1.38), and third-most disadvantaged census tracts (HR, 1.18; 95% CI, 1.02-1.37) compared with children in the least disadvantaged tracts. CONCLUSIONS Children living in the most disadvantaged neighborhoods experienced a significantly higher risk of mortality, indicating the important role of socioeconomic disparities in the survival of pediatric CNS tumors. IMPACT The demographic and socioeconomic disparities identified by this study should be considered when planning treatment strategies for these susceptible groups and thus, lead to a better outcome in socioeconomically disadvantaged children diagnosed with CNS tumors.

Abstract
INTRODUCTION The growing number of survivors of childhood cancer, with many years of life ahead, demonstrates the increasing clinical and public health relevance of investigating the risks of social and socioeconomic impairment after a childhood cancer diagnosis and the life-saving treatment. To enrich understanding of the mental, social and socioeconomic difficulties that childhood cancer survivors may face during their life-course, identify particularly vulnerable survivors and overcome the limitations of previous research, we initiated the Socioeconomic Consequences in Adult Life after Childhood Cancer in Scandinavia (SALiCCS) research programme. METHODS This Nordic cross-border research programme is a collaboration between the Danish Cancer Society, the Finnish Cancer Registry and Karolinska Institutet to investigate a broad range of mental, social and socioeconomic conditions in long-term childhood cancer survivors in Denmark, Finland and Sweden. SALiCCS is based on a registry-based matched cohort design, comprising five-year survivors of cancer diagnosed at ages 0-19 years (1971-2008 in Denmark, 1971-2009 in Finland, 1971-2011 in Sweden), age-, sex- and country-matched population comparisons and sibling comparisons who were followed over time. Outcomes of interest included mental disorders, educational achievements, employment and profession, family life and the need of social security benefits. Individual-level data linkage among various national registries provided the data for the research programme. RESULTS The SALiCCS core population comprises 21,292 five-year survivors, 103,303 population comparisons and 29,644 siblings as a second comparison group. The most common diagnoses in survivors were central nervous system tumours, leukaemias and lymphomas. DISCUSSION SALiCCS is the largest, most comprehensive population-based research initiative in this field, based on high-quality registry data with minimal risk of bias. The findings will be informative for evidence-based survivorship care targeting not only somatic late effects but also psychosocial impairments.

Abstract
Treatment advances over the past five decades have resulted in significant improvements in survival from childhood cancer. Although survival rates are relatively high, social disparities in outcomes have been sometimes observed. In a population-based study, we investigated social inequalities by sex and deprivation in treatment receipt in childhood cancer in Ireland. Cancers incident in people aged 0 to 19 during 1994 to 2012 and treatments received were abstracted from the National Cancer Registry Ireland. Multivariable modified Poisson regression with robust error variance (adjusting for age, and year) was used to assess associations between sex and deprivation category of area of residence at diagnosis and receipt of cancer-directed surgery, chemotherapy or radiotherapy. Three thousand seven hundred and four childhood cancers were included. Girls were significantly less likely than boys to receive radiotherapy for leukemia overall (relative risk [RR] = 0.70; 95% confidence interval [CI] = 0.50-0.98), and acute lymphoblastic leukemia specifically (RR = 0.54; 95% CI = 0.36-0.79), and surgery for central nervous system (CNS) overall (RR = 0.83; 95% CI = 0.74-0.93) and other CNS (RR = 0.76; 95% CI = 0.60-0.96). Girls were slightly less likely to receive chemotherapy for non-Hodgkin lymphoma and surgery for Hodgkin lymphoma (HL), but these results were not statistically significant. Children residing in more deprived areas were significantly less likely to receive chemotherapy for acute myeloid leukemia or surgery for lymphoma overall and HL, but more likely to receive chemotherapy for medulloblastoma. These results may suggest social inequalities in treatment receipt for childhood cancers. Further research is warranted to explore whether similar patterns are evident in other childhood cancer populations and to better understand the reasons for the findings.

Abstract
Despite the abundance of epidemiological evidence concerning the association between pesticide exposure and adverse health outcomes including acute childhood leukemia (AL), evidence remains inconclusive, and is inherently limited by heterogeneous exposure assessment and multiple statistical testing. We performed a literature search of peer-reviewed studies, published until January 2021, without language restrictions. Summary odds ratios (OR) and 95% confidence intervals (CI) were derived from stratified random-effects meta-analyses by type of exposure and outcome, exposed populations and window of exposure to address the large heterogeneity of existing literature. Heterogeneity and small-study effects were also assessed. We identified 55 eligible studies (n = 48 case-control and n = 7 cohorts) from over 30 countries assessing >200 different exposures of pesticides (n = 160,924 participants). The summary OR for maternal environmental exposure to pesticides (broad term) during pregnancy and AL was 1.88 (95%CI: 1.15-3.08), reaching 2.51 for acute lymphoblastic leukemia (ALL; 95%CI: 1.39-4.55). Analysis by pesticide subtype yielded an increased risk for maternal herbicide (OR: 1.41, 95%CI: 1.00-1.99) and insecticide (OR: 1.60, 95%CI: 1.11-2.29) exposure during pregnancy and AL without heterogeneity (p = 0.12-0.34). Meta-analyses of infant leukemia were only feasible for maternal exposure to pesticides during pregnancy. Higher magnitude risks were observed for maternal pesticide exposure and infant ALL (OR: 2.18, 95%CI: 1.44-3.29), and the highest for infant acute myeloid leukemia (OR: 3.42, 95%CI: 1.98-5.91). Overall, the associations were stronger for maternal exposure during pregnancy compared to childhood exposure. For occupational or mixed exposures, parental, and specifically paternal, pesticide exposure was significantly associated with increased risk of AL (ORparental: 1.75, 95%CI: 1.08-2.85; ORpaternal: 1.20, 95%CI: 1.07-1.35). The epidemiological evidence, supported by mechanistic studies, suggests that pesticide exposure, mainly during pregnancy, increases the risk of childhood leukemia, particularly among infants. Sufficiently powered studies using repeated biomarker analyses are needed to confirm whether there is public health merit in reducing prenatal pesticide exposure.

Abstract
BACKGROUND Childhood cancer survival currently exceeds 80 % five years after diagnosis in high-income countries. In this study, we aimed to describe long-term trends and to investigate socioeconomic and spatial disparities in childhood cancer survival. METHODS The study included 28,073 cases recorded in the French National Registry of Childhood Cancers from 2000 to 2015. Contextual census data (deprivation indices, population density, spatial accessibility to general practitioners) were allocated to each case based on the residence at diagnosis. Overall survival (OS) and conditional 10-year OS for 5-year survivors were estimated for all cancers combined and by diagnostic group and subgroup. Comparisons were conducted by sex, age at diagnosis, period of diagnosis, and contextual indicators. Hazard ratios for death were estimated using Cox models. RESULTS All cancers combined, the OS reached 82.8 % [95 % CI: 82.4-83.3] at 5 years and 80.8 % [95 % CI: 80.3-81.3] at 10 years. Conditional 10-year OS of 5-year survivors reached 97.5 % [95 % CI: 97.3-97.7] and was higher than 95 % for all subgroups except osteosarcomas and most subgroups of the central nervous system. In addition to disparities by sex, age at diagnosis, and period of diagnosis, we observed a slight decrease in survival for cases living in the most deprived areas at diagnosis, not consistent across diagnostic groups. CONCLUSION Our results confirm the high 5-year survival for childhood cancer and show an excellent 10-year conditional survival of 5-year survivors. Additional individual data are needed to clarify the factors underlying the slight decrease in childhood cancer survival observed in the most deprived areas.

Abstract
Research Objective: Initiatives to address social determinants of health (SDOH) and measure health-related social needs (HRSN) within clinic settings are increasing. However, few have focused on the specific needs of Asian Americans (AA). We examine the prevalence of HRSN during a period spanning the COVID-19 pandemic to inform strategies to improve cancer screening and primary care among AA patients. Methods: We implemented a self-administered HRSN screening tool in English and Chinese, traditional (T) or simplified (S) text, within a hospital-affiliated, outpatient primary care practice predominantly serving AA in New Jersey. HRSN items included food insecurity, transportation barriers, utility needs, interpersonal violence, housing instability, immigration history, and neighborhood perceptions on cohesion and trust. We conducted medical chart reviews for a subset of participants to explore the relationship between HRSN and history of cancer screening. Results: Among 236 participants, most were Asian (74%), non-US born (79%), and privately insured (57%). One-third responded in Chinese (37%). Half reported having ≥1 HRSN. Interpersonal violence was high across all participants. Transportation needs were highest among Chinese-T participants, while food insecurity and housing instability were higher among Chinese-S participants. Lower-income patients had higher odds of having ≥2 HRSN (OR:2.53, 95% CI: 1.12, 5.98). Older age and public insurance/uninsured were significantly associated with low neighborhood perceptions. Conclusions: We observed higher than anticipated reports of HRSN among primary care patients in a suburban, hospital-affiliated practice serving AA. Low neighborhood perceptions, particularly among Chinese-S participants, highlight the importance of addressing broader SDOH among insured, suburban AA patients. These study findings inform the need to augment HRSN identification to adequately address social needs that impact health outcomes and life course experiences for Asian patients. As HRSN measuring efforts continue, and COVID-19's impact on the health of minority communities emerge, it will be critical to develop community-specific referral pathways to connect AA to resources for HRSN and continue to address more upstream social determinants of health for those who are disproportionately impacted.

Abstract
BACKGROUND Most of the world's population is not covered by cancer surveillance systems or vital registration, and worldwide/UN-regional cancer incidence is estimated using a variety of methods. Quantifying the cancer burden in children (<15 years) is more challenging than in adults; childhood cancer is rare and often presents with non-specific symptoms that mimic those of more prevalent infectious and nutritional conditions. METHODS A Baseline Model (BM) was constructed comprising a set of quality assured sex- and age-specific cancer rates derived from the US Surveillance, Epidemiology and End Results (SEER) program, for diagnostic groups of the International Classification of Childhood Cancers (ICCC-3) 3rd edition, and information on a known risk factor for endemic Burkitt lymphoma and Kaposi's sarcoma. These rates were applied to global country-level population data for 2015 to estimate the global and regional incidence of childhood cancer. Results were compared to GLOBOCAN 2018, extrapolations from the International Incidence of Childhood Cancer (IICC-3) and estimates from the Global Childhood Cancer (GCC) model (based on IICC-3 data combined with information on health care systems and other parameters). RESULTS The BM estimated 360,114 total childhood cancers occurring worldwide in 2015; 54% in Asia and 28% in Africa. BM estimated standardised rates ranged from ∼178 cases per million in Europe and North America, through to ∼218 cases per million in West and Middle Africa. Totals from GLOBOCAN and extrapolations from the IICC-3 study were lower (44.6% and 34.7% respectively), but the estimate from the GCC model was 10.2% higher. In all models, agreement was good in countries with very high human development index (HDI), but more variable in countries with medium and low HDIs; the discrepancies correlating with registration coverage across these settings. CONCLUSION Disagreements between the BM estimates and other sources occur in areas where health systems are insufficiently equipped to provide adequate access to diagnosis, treatment, and supportive care. Incorporating aetiological evidence into the BM enabled the estimation of the additional burden of Burkitt lymphoma and Kaposi sarcoma; similar adjustments could be applied to other cancers, as and when information becomes available.

METHODS We performed a retrospective single-center study of 125 children diagnosed with ALL between 2010 and 2016. Standard forms were used for data collection of variate clinical and paraclinical parameters. RESULTS The children were predominantly male (64.8%) and their median age at diagnosis was 5 years. A total of 107 patients were diagnosed with precursor B-cell acute lymphoblastic leukemia (BCP)-ALL and 18 with T-cell acute lymphoblastic leukemia T-ALL. Multiplex reverse transcription polymerase chain reaction RT-PCR assay for ETV6-RUNX1, BCR-ABL, E2A-PBX1, KMT2A-AFF1, and STIL-TAL1 fusion genes was performed in 111 patients. ETV6-RUNX1 translocation was detected in 18.9% of patients, while BCR-ABL1 and E2A-PBX1 rearrangements were seen in 2.7% and 3.6%, respectively. Complete remission at the end of induction phase was obtained in 89.6% of patients. The overall relapse rate was 11.2%, with 11 early and 3 late relapses. The 5-year overall survival rate in BCP-ALL was 81.6% and in T-ALL 71.4%. CONCLUSIONS The 5-year overall and event-free survival rates in our study were slightly lower than those reported in developed countries, so the patients' outcomes are encouraging.

Abstract
Acute leukemia is the most common childhood cancer and has been associated with exposure to environmental carcinogens. This study aimed to identify clusters of acute childhood leukemia (ACL) cases and analyze their relationship with proximity to industrial sources of air pollution in three capital cities in Colombia during 2000-2015. Incident ACL cases were obtained from the population cancer registries for the cities of Bucaramanga, Cali, and Medellín. The inventory of industrial sources of emissions to the air was obtained from the regional environmental authorities and industrial conglomerates were identified. The Kulldorf's circular scan test was used to detect city clusters and to identify clusters around industrial conglomerates. Multivariable spatial modeling assessed the effect of distance and direction from the industrial conglomerates controlling for socioeconomic status. We identified industrials sectors within a buffer of 1 km around industrial conglomerates related to the ACL clusters. Incidence rates showed geographical heterogeneity with low spatial autocorrelation within cities. The spatio-temporal tests identified one cluster in each city. The industries located within 1 km around the ACL clusters identified in the three cities represent different sectors. Exposure to air pollution from industrial sources might be contributing to the incidence of ACL cases in urban settings in Colombia.

Abstract
BACKGROUND Few studies have evaluated social determinants of outcomes disparities for children with acute lymphoblastic leukemia (ALL). We investigated the association of area deprivation index (ADI), a measure of neighborhood socioeconomic disadvantage, with overall survival (OS) among children and adolescents with ALL. PROCEDURE We obtained demographic and clinical data, geocoded addresses at diagnosis, and vital status on all Texas children diagnosed with ALL from 1995 to 2011 (N = 4104). Using the US Census Bureau 2010 geography, we computed ADI scores for all census tracts in Texas and grouped the tracts into quartiles: least, third-most, second-most, and most disadvantaged. We mapped children to ADI quartiles based on residence at diagnosis, and estimated OS using Cox regression adjusting for sex, race/ethnicity, age, and metropolitan/nonmetropolitan residence. RESULTS Five-year OS ranged from 89% (95% confidence interval [CI] 87-91%) for children in the least disadvantaged tracts to 79% (95% CI 76-81%) for children in the most disadvantaged tracts (P = 4E-7). An elevated hazard ratio (HR) for death was observed for children in the most disadvantaged tracts (HR 1.57, 95% CI 1.23-2.00), and trends toward increased mortality were observed in the third-most and second-most disadvantaged tracts (HR 1.23, 95% CI 0.97-1.57 and HR 1.27, 95% CI 0.99-1.62, respectively). In stratified analyses, area disadvantage was more strongly associated with OS in males than females. CONCLUSIONS Neighborhood socioeconomic disadvantage is associated with inferior OS in this analysis of over 4100 children with ALL, highlighting the substantial contributions of social-environmental factors to childhood cancer survival. This association was stronger in males than females.

Abstract
BACKGROUND The objective was to investigate factors associated with patient-related timing (PRT) to seek healthcare and health service-related timing (HSRT) to diagnose cancer and provide treatment to children without social security in Mexico. PROCEDURE A cross-sectional survey was conducted in 13 Ministry of Health hospitals in the states of Chihuahua, Jalisco, Mexico City, Morelos, Oaxaca, Puebla, Queretaro, State of Mexico, and Tlaxcala. Study participants were parents of recently diagnosed pediatric cancer patients (≤ 17 years of age). Three groups of factors were investigated: (1) patients (child and parent characteristics); (2) healthcare providers (HCPs) (first-contact HCP, institution, perceptions of barriers to healthcare, etc.); and (3) disease factors (cancer type/site, stage/risk at diagnosis). PRT and HSRT-associated factors were identified using multiple negative binomial regressions. RESULTS The study included 265 children; 49% sought care when symptoms first appeared. The median PRT was seven days, and the median HSRT was 40 days. Parents' perceptions of long wait times for appointments were associated with longer PRT and HSRT. Residing in the lowest or highest socioeconomic regions and persistent or worsening symptoms increased the probability of longer PRT. Older patient age, HCP requests for imaging tests or prescription for steroids, a higher number of doctors consulted, having a urinary tract cancer, and having an advanced stage or high-risk cancer increased the probability of longer HSRT. CONCLUSION Strategies to shorten lag time from symptom onset to diagnosis and treatment are urgently needed for childhood cancers in Mexico.

Abstract
BACKGROUND Neuroblastoma (NB) is a heterogeneous disease with variable outcomes among countries. Little is known about NB in low- and middle-income countries (LMICs).
AIM The aim of this review was to evaluate regional management protocols and challenges in treating NB in paediatric oncology units in LMICs compared to high-income countries (HICs).
METHODS PubMed, Global Health, Embase, SciELO, African Index Medicus and Google Scholar were searched for publications with keywords pertaining to NB, LMICs and outcomes. Only English language manuscripts and abstracts were included. A descriptive review was done, and tables illustrating the findings were constructed.
RESULTS Limited information beyond single-institution experiences regarding NB outcomes in LMICs was available. The disease characteristics varied among countries for the following variables: sex, age at presentation, MYCN amplification, stage and outcome. LMICs were found to be burdened with a higher percentage of stage 4 and high-risk NB compared to HICs. Implementation of evidence-based treatment protocols was still a barrier to care. Many socioeconomic variables also influenced the diagnosis, management and follow-up of patients with NB.
CONCLUSION Patients presented at a later age with more advanced disease in LMICs. Management was limited by the lack of resources and genetic studies for improved NB classification. Further research is needed to develop modified diagnostic and treatment protocols for LMICs in the face of limited resources.

Abstract
Abstract
Background
Differences in access, delivery and utilisation of health care may impact childhood and adolescent cancer survival. We evaluated whether insurance coverage impacts survival among US children and adolescents with cancer diagnoses, overall and by age group, and explored potential mechanisms.
Methods
Data from 58 421 children (aged ≤14 years) and adolescents (15–19 years), diagnosed with cancer from 2004 to 2010, were obtained from the National Cancer Database. We examined associations between insurance status at initial diagnosis or treatment and diagnosis stage; any treatment received; and mortality using logistic regression, Cox proportional hazards (PH) regression, restricted mean survival time (RMST) and mediation analyses.
Results
Relative to privately insured individuals, the hazard of death (all-cause) was increased and survival months were decreased in those with Medicaid [hazard ratio (HR) = 1.27, 95% confidence interval (CI): 1.22 to 1.33; and −1.73 months, 95% CI: −2.07 to −1.38] and no insurance (HR = 1.32, 95% CI: 1.20 to 1.46; and −2.13 months, 95% CI: −2.91 to −1.34). The HR for Medicaid vs. private insurance was larger (pinteraction <0.001) in adolescents (HR = 1.52, 95% CI: 1.41 to 1.64) than children (HR = 1.16, 95% CI: 1.10 to 1.23). Despite statistical evidence of PH assumption violation, RMST results supported all interpretations. Earlier diagnosis for staged cancers in the Medicaid and uninsured populations accounted for an estimated 13% and 19% of the survival deficit, respectively, vs. the privately insured population. Any treatment received did not account for insurance-associated survival differences in children and adolescents with cancer.
Conclusions
Children and adolescents without private insurance had a higher risk of death and shorter survival within 5 years following cancer diagnosis. Additional research is needed to understand underlying mechanisms.

Abstract
Background Population-based EUROCARE-5 studies demonstrated that childhood cancer survival rates in Lithuania were 10-20% lower than the European mean. We aimed to analyse the change in the outcome of treatment of paediatric malignancies in Lithuania over 30 years. Methods A single-centre retrospective analysis of children below 18 years of age treated for cancer at Vilnius University Hospital Santaros Klinikos between 1982 and 2011 was carried out. The minimal requirement of 5-year follow-up after diagnosis was specified for survival estimation. The vital status was assessed using data from the population-based Lithuanian Cancer Registry. To evaluate changes over time, the entire cohort was split into three groups according to the time of diagnosis: 1982-1991, 1992-2001, and 2002-2011. Results A total of 1268 children met the inclusion criteria. The shortest median follow-up was 8.9 (IQR 6.4-11.5) years for patients treated in the third decade. The 5-year overall survival of the entire cohort increased from 37.3% (95% CI 30.2-44.3) in 1982-1991 to 70.7% (95% CI 66.4-74.1) in 2002-2011 (p < 0.0001). The same trend was evident when calculated separately for leukaemia (p < 0.0001), lymphoma (p < 0.0005), and solid tumours (p < 0.004). The percentage of cure rose from zero in the early years of the period analysed to 80% in 2010 and 2011. The improvement in the treatment outcome was attributable to the reduction of treatment-related mortality from 45.8% in 1982-1991 to 12.4% in 2002-2011 and disease recurrence from 30.4% to 19.6% for the same periods, respectively. Conclusions Significant progress in the cure rate of children treated for cancer at our institution was observed over 30 years. Collaborative national and international clinical and research efforts are crucial to ensure further advances in care and cure.

Abstract
Since the 1960s, paediatric oncologists have gradually become better organised in large study groups and participation in clinical trials is today considered as the standard of care, with most children with cancer in Europe and North America being enrolled on available treatment protocols. Chemotherapy is nowadays the main element of therapy, but irradiation is still required for some patients. With the advent of multimodality therapy and supportive care, five-year cancer survival exceeds 80 % in most European and North American countries today. The substantial improvements in survival led to a constantly growing population of childhood cancer survivors. Concerns regarding the risk of late effects of the intensive cancer treatment at a young age, together with increasing numbers of survivors, have directed attention towards survivorship research. Survivors of childhood cancer are at longstanding risk of various severe somatic and mental health conditions attributable to the cancer and its treatment, as well as adverse social and socioeconomic consequences, and diminished psychological well-being and quality of life. It is, however, important to stress that some survivors have no or very mild adverse health conditions. Nevertheless, joint efforts are warranted for the care and long-term follow-up of childhood cancer patients. With this article, we provide a comprehensive overview of improvements in survival and treatment modalities over time, as well as the related somatic and mental late effects, and social and socioeconomic difficulties that these children might encounter later in life.
