Educational attainment among adult survivors of childhood cancer in Great Britain: a population-based cohort study

Burden of Childhood Cancer and the Social and Economic Challenges in Adulthood: A Systematic Review and Meta-Analysis

Importance

Significant advancements in pediatric oncology have led to a continuously growing population of survivors. Although extensive research is being conducted on the short-, medium-, and long-term somatic effects, reports on psychosocial reintegration are often conflicting; therefore, there is an urgent need to synthesize the evidence to obtain the clearest understanding and the most comprehensive answer.

Objective

To provide a comprehensive review and analysis of the socioeconomic attainment of childhood cancer survivors (CCSs) compared with their unaffected peers.

Data Sources

A systematic review and meta-analysis was conducted using data obtained from a comprehensive search of MEDLINE (via PubMed), Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases on October 23, 2021; the search was updated until July 31, 2023.

Study Selection

Eligible articles reported on educational attainment, employment, family formation, quality of life (QoL), or health-risk behavior-related outcomes of CCSs, and compared them with their unaffected peers. Study selection was performed in duplicate by 4 blinded independent coauthors.

Data Extraction and Synthesis

Data extraction was performed in duplicate by 4 independent authors following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Outcome measures were odds ratios (ORs) and mean differences with 95% CIs; data were pooled using a random-effects model.

Results

The search identified 43 913 articles, 280 of which were eligible for analysis, reporting data on a total of 389 502 survivors. CCSs were less likely to complete higher levels of education (OR, 0.69; 95% CI, 0.40-1.18), had higher odds of health-related unemployment (OR, 2.94; 95% CI, 1.90-4.57), and showed lower rates of marriage (OR, 0.72; 95% CI, 0.63-0.84) and parenthood (OR, 0.60; 95% CI, 0.49-0.74) compared with population-based controls.

Conclusion and Relevance

Study findings suggest that CCSs face several socioeconomic difficulties; as a result, the next goal of pediatric oncology should be to minimize adverse effects, as well as to provide lifelong survivorship support aimed at maximizing social reintegration.

Educational attainment in survivors of childhood cancer in Denmark, Finland, and Sweden

BACKGROUND

Survivors of childhood cancer may face difficulties at school. We investigated whether childhood cancer affects attainment of upper secondary education, in a register-based cohort study from Denmark, Finland, and Sweden, where we limit bias from selection and participation.

METHODS

From the national cancer registers, we identified all long-term survivors of childhood cancer diagnosed aged 0-14 years in 1971-2005 (n = 7629), compared them to matched population comparisons (n = 35,411) and siblings (n = 6114), using odds ratios (OR) and 95% confidence intervals (CI).

RESULTS

Overall, 6127 survivors (80%) had attained upper secondary education by age 25, compared to 84% among comparison groups. Elevated OR for not attaining this level were mainly confined to survivors of central nervous system (CNS) tumours (ORSurv_PopComp2.05, 95%CI: 1.83-2.29). Other risk groups were survivors who had spent more time in hospital around cancer diagnosis and those who had hospital contacts in early adulthood, particularly psychiatric. Survivors of all cancer types were less likely to have attained upper secondary education without delay.

CONCLUSIONS

Although survivors of childhood cancer experienced delays in their education, many had caught up by age 25. Except for survivors of CNS tumours, survivors attained upper secondary education to almost the same extent as their peers.

Educational and occupational outcomes in Swedish children treated for sarcomas: A nationwide registry-based study

BACKGROUND

Many children treated for cancer experience a negative impact on their academic performance; however, most studies of children treated for sarcomas have not investigated academic performance. Our aim was to explore how Swedish children treated for sarcomas perform academically, as well as how they adjust to life afterwards.

PROCEDURE

We compared 167 pediatric sarcoma survivors with 776 matched, non-sibling controls without a history of cancer, in a retrospective cohort study using data from nationwide registries. Primary outcomes were grades at the end of compulsory education, high school eligibility, post-compulsory education (i.e., education after school Year 9), employment, and sickness or activity compensation.

RESULTS

Pediatric sarcoma survivors were more likely to be ineligible for high school (odds ratio [OR] 1.76; p = .045) and more likely to fail Swedish (OR 2.12; p = .046), mathematics (OR 2.27; p = .011), and/or physical education (OR 2.24; p = .004), compared with controls. Survivors were less likely to have been employed (OR 0.58; p = .027) and received sickness or activity compensation more often (OR 2.49; p = .008) compared with controls.

CONCLUSIONS

Pediatric sarcoma survivors have poorer academic performance compared to peers without cancer in multiple school subjects. Survivors seem to catch up during post-compulsory education, but might struggle to find employment.

Cardiorespiratory fitness and health-related quality of life in survivors of childhood central nervous system tumours

PURPOSE

We assessed cardiorespiratory fitness and health-related quality of life (HRQoL) in survivors of childhood central nervous system (CNS) tumours.

METHODS

Participants were recruited from the National Children's Cancer Service in Children's Health Ireland at Crumlin. Inclusion criteria included diagnosis of a primary CNS tumour, aged between 6 and 17 years, between 3 months and 5 years post completion of oncology treatment, independently mobile, and deemed clinically appropriate to participate by treating oncologist. Cardiorespiratory fitness was assessed using the six-minute walk test. HRQoL was assessed with the PedsQL Generic Core Scales, Version 4.0.

RESULTS

Thirty-four participants (n = 16 male) were recruited, with a mean age of 12.21 ± 3.31 years and a mean time since completion of oncology treatment of 2.19 ± 1.29 years. Mean six-minute walk distance (6MWD) achieved was 489.56 ± 61.48 m, equating to the 8^th percentile overall. 6MWD was significantly reduced when compared to predicted population norms (p < 0.001). PedsQL parent proxy-report and child-report scores were significantly lower when compared to healthy paediatric norms (p < 0.001 - p = 0.011). A significant positive correlation was found between 6MWD and both parent proxy-report (r = 0.55, p < 0.001) and child-report (r = 0.48, p = 0.005) PedsQL total scores.

CONCLUSION

Survivors of childhood CNS tumours present with impaired cardiorespiratory fitness and HRQoL. Higher levels of cardiorespiratory fitness are associated with higher levels of HRQoL.

IMPLICATIONS FOR CANCER SURVIVORS

Routine screening of cardiorespiratory fitness and HRQoL in survivors of childhood CNS tumours may be beneficial. Healthcare providers should encourage and provide education on the potential benefits of physical activity to improve overall quality of life.

Educational pathways of childhood cancer survivors-a parental cohort

PURPOSE

Using the International Standard Classification of Education (ISCED), we examined the educational and vocational pathways of two comparable, parental cohorts: childhood cancer survivors (CCS) and their siblings. Both cohorts had previously entered parenthood. The aim of the study was to elucidate whether childhood cancer and treatment affect the educational pathways chosen by parents who are former patients.

METHODS

We analysed data that was collected from childhood cancer survivors and their siblings regarding their offspring's health within the FeCt Multicentre Offspring Study (conducted 2013-2016). We evaluated and compared the professional pathways of (i) all participating survivors and all participating siblings and those of (ii) survivors and their biological siblings.

RESULTS

Overall information on parental gender, age, and education were available from 1077 survivors and 246 siblings (group (i)). The majority of participants were female with a mean age of 35.2 (survivor) and 37.9 (sibling) years at time of survey. For subgroup (ii), analysis information was available on 191 survivors and 210 siblings. Fathers achieved university degrees significantly more often than mothers (p = 0.003 (i), p < 0.001 (ii)). The distribution of professional education was not significantly different between cancer survivors and siblings in either cohort (i) or (ii).

CONCLUSIONS

Regarding our research on the educational and vocational trajectory of CCS, patients can be reassured that family planning and vocational education are well compatible. Inequalities regarding gender-specific educational pathways remain to be addressed.

IMPLICATIONS FOR CANCER SURVIVORS

CCS should monitor their fertility status regularly and, if necessary, cryopreserve germ cells or tissue in order to optimize their family planning. Educational opportunities should be pursued as desired and with confidence. Local as well as European aftercare programs can assist with family planning and education.

International Survey of Pediatric Oncologists' Beliefs and Communication Practices Regarding Symptom Self-Monitoring by Childhood Cancer Survivors

PURPOSE

Childhood cancer survivors report self-monitoring for and worrying about symptoms of disease recurrence and secondary cancers, although symptom-related worry is associated with poorer health-related quality of life. This survey captured pediatric oncologists' beliefs and communication practices regarding symptom self-monitoring for childhood cancer survivors.

METHODS

Using a closed-loop snowball sampling technique, pediatric oncologists completed an online survey regarding the importance of symptom self-monitoring for off-therapy patients, the degree to which symptom self-monitoring was perceived to cause stress and worry, and communication practices.

RESULTS

196 pediatric oncologists (White [78%]; female [64%]; M_age = 47 years) from every continent except Antarctica participated. Oncologists believed it is important for off-therapy patients to self-monitor for symptoms of cancer recurrence (90%) and treatment late effects (94%), although some noted that recurrence (30%) and late effects (55%) are typically detected by routine surveillance before symptoms appear. Oncologists varied in their beliefs that off-therapy patients do (31%) or do not (31%) worry unnecessarily about symptoms of recurrence. Two thirds (62%) of oncologists reported often/always discussing with off-therapy patients which symptoms could indicate cancer recurrence, whereas fewer than half (43%) often/always discussed which symptoms were unlikely to indicate recurrence. Oncologists identified a need for education regarding how to communicate around symptom self-monitoring and the potential utility of a screening tool to identify those who worry excessively.

CONCLUSION

Despite nearly universal belief that their off-therapy patients should self-monitor for symptoms of disease recurrence and late effects, a substantial proportion of pediatric oncologists do not counsel patients on symptom self-monitoring. Since nearly one-third believe that off-therapy patients worry unnecessarily about symptoms of recurrence, improving patient education regarding which symptoms are and are not medically concerning could decrease stress and improve health-related quality of life for pediatric cancer survivors.

Association of Modifiable Health Conditions and Social Determinants of Health With Late Mortality in Survivors of Childhood Cancer

IMPORTANCE

Associations between modifiable chronic health conditions (CHCs), social determinants of health, and late mortality (defined as death occurring ≥5 years after diagnosis) in childhood cancer survivors are unknown.

OBJECTIVE

To explore associations between modifiable CHCs and late mortality within the context of social determinants of health.

DESIGN, SETTING, AND PARTICIPANTS

This longitudinal cohort study used data from 9440 individuals who were eligible to participate in the St Jude Lifetime Cohort (SJLIFE), a retrospective cohort study with prospective clinical follow-up that was initiated in 2007 to characterize outcomes among childhood cancer survivors. Eligible individuals had survived 5 or more years after childhood cancer diagnosis, were diagnosed between 1962 and 2012, and received treatment at St Jude Children's Research Hospital were included in mortality estimates. A total of 3407 adult SJLIFE participants (aged ≥18 years) who completed an on-campus assessment were included in risk factor analyses. Vital status, date of death, and cause of death were obtained by linkage with the National Death Index (coverage from inception to December 31, 2016). Deaths occurring before inception of the National Death Index were obtained from the St Jude Children's Research Hospital Cancer Registry. Data were analyzed from June to December 2022.

EXPOSURES

Data on treatment exposures and causes of death were abstracted for individuals who were eligible to participate in the SJLIFE study. Information on modifiable CHCs (dyslipidemia, hypertension, diabetes, underweight or obesity, bone mineral deficiency, hypogonadism, hypothyroidism, and adrenal insufficiency, all graded by the modified Common Terminology Criteria for Adverse Events), healthy lifestyle index (smoking status, alcohol consumption, body mass index [calculated as weight in kilograms divided by height in meters squared], and physical activity), area deprivation index (ADI; which measures neighborhood-level socioeconomic disadvantage), and frailty (low lean muscle mass, exhaustion, low energy expenditure, slowness, and weakness) was obtained for participants.

MAIN OUTCOMES AND MEASURES

National Death Index causes of death were used to estimate late mortality using standardized mortality ratios (SMRs) and 95% CIs, which were calculated based on US mortality rates. For the risk factor analyses (among participants who completed on-campus assessment), multivariable piecewise exponential regression analysis was used to estimate rate ratios (RRs) and 95% CIs for all-cause and cause-specific late mortality.

RESULTS

Among 9440 childhood cancer survivors who were eligible to participate in the SJLIFE study, the median (range) age at assessment was 27.5 (5.3-71.9) years, and the median (range) duration of follow-up was 18.8 (5.0-58.0) years; 55.2% were male and 75.3% were non-Hispanic White. Survivors experienced increases in all-cause mortality (SMR, 7.6; 95% CI, 7.2-8.1) and health-related late mortality (SMR, 7.6; 95% CI, 7.0-8.2). Among 3407 adult SJLIFE participants who completed an on-campus assessment, the median (range) age at assessment was 35.4 (17.9-69.8) years, and the median (range) duration of follow-up was 27.3 (7.3-54.7) years; 52.5% were male and 81.7% were non-Hispanic White. Models adjusted for attained age, sex, race and ethnicity, age at diagnosis, treatment exposures, household income, employment status, and insurance status revealed that having 1 modifiable CHC of grade 2 or higher (RR, 2.2; 95% CI, 1.2-4.0; P = .01), 2 modifiable CHCs of grade 2 or higher (RR, 2.6; 95% CI, 1.4-4.9; P = .003), or 3 modifiable CHCs of grade 2 or higher (RR, 3.6; 95% CI, 1.8-7.1, P < .001); living in a US Census block with an ADI in the 51st to 80th percentile (RR, 5.5; 95% CI, 1.3-23.5; P = .02), an ADI in the 81st to 100th percentile (RR, 8.7; 95% CI, 2.0-37.6; P = .004), or an unassigned ADI (RR, 15.7; 95% CI, 3.5-70.3; P < .001); and having frailty (RR, 2.3; 95% CI, 1.3-3.9; P = .004) were associated with significant increases in the risk of late all-cause death. Similar associations were observed for the risk of late health-related death (1 modifiable CHC of grade ≥2: RR, 2.2 [95% CI, 1.1-4.4; P = .02]; 2 modifiable CHCs of grade ≥2: RR, 2.5 [95% CI, 1.2-5.2; P = .01]; 3 modifiable CHCs of grade ≥2: RR, 4.0 [95% CI, 1.9-8.4; P < .001]; ADI in 51st-80th percentile: RR, 9.2 [95% CI, 1.2-69.7; P = .03]; ADI in 81st-100th percentile: RR, 16.2 [95% CI, 2.1-123.7; P = .007], unassigned ADI: RR, 27.3 [95% CI, 3.5-213.6; P = .002]; and frailty: RR, 2.3 [95% CI, 1.2-4.1; P = .009]).

CONCLUSIONS AND RELEVANCE

In this cohort study of childhood cancer survivors, living in a Census block with a high ADI and having modifiable CHCs were independently associated with an increased risk of late death among survivors of childhood cancer. Future investigations seeking to mitigate these factors will be important to improving health outcomes and developing risk-stratification strategies to optimize care delivery to childhood cancer survivors.

Radiotherapy-Induced Neurocognitive Dysfunction in Brain Tumor Survivors: Burden and Rehabilitation

Radiotherapy-induced neurocognitive dysfunction after cranial irradiation has an incidence of 40-100%. It may affect both children and adults, and represents a significant burden not only on ill individuals and their caregivers but also on the health care system and society in general. Multiple patient-, tumor-, and treatment-related factors may contribute to development of this complication, but its pathophysiological mechanisms are still not understood clearly. It is hoped that introduction of more advanced techniques for conformal irradiation, optimized dosimetry, and specific prophylactic measures will decrease the risk of neurocognitive decline in brain tumor survivors in the future.

Identifying the important social outcomes for childhood cancer survivors: an e-Delphi study protocol

INTRODUCTION

Optimising the health of childhood cancer survivors is important given the high long-term survival rate coupled with a significant late effects burden. Included within the WHO's definition of 'Health' are social outcomes. These are of interest given their impact on adult functioning within society, complex interactions with physical and mental health outcomes and potential for cross generational effects. Categories included within the definition of social outcomes are ill defined leading to potential gaps in research and service provision which could affect the ability of survivors to achieve their maximal potential. An e-Delphi study will be used to achieve expert consensus on the most important social outcomes for childhood cancer survivors to inform future research and ultimately, service provision.

METHODS AND ANALYSIS

A heterogeneous sample of at least 48 panel members will be recruited across four groups chosen to provide different perspectives on the childhood cancer journey: childhood cancer survivors, health professionals, social workers and teachers. Purposive sampling from a UK, regional long-term follow-up clinic will be used to recruit a representative sample of survivors. Other panel members will be recruited through local channels and national professional working groups. Opinions regarding breakdown and relevance of categories of social outcome will be collected through 3-5 rounds of questionnaires using an e-Delphi technique. Open ended, 7-point Likert scale and ranking questions will be used. Each round will be analysed collectively and per group to assess inter-rater agreement. Agreement and strength of agreement will be indicated by a median score of 6 or 7 and mean absolute deviation from the median, respectively.

ETHICS AND DISSEMINATION

Ethical approval for this study has been granted by Regional Ethics Committee 4, West of Scotland (ID 297344). Study findings will be disseminated to involved stakeholders, published in a peer-reviewed journal and presented at conferences.

A narrative review of the late effects of paediatric cancer treatment within an educational setting: Existing evidence and where do we go from here?

OBJECTIVES

The late effects of paediatric cancer treatment within an educational context are an area that is relatively under researched within the United Kingdom.

METHODS

To support this narrative review, systematic searches were conducted in key scientific databases between May and December 2020.

RESULTS

Upon reviewing literature within this field, there are key considerations that should be addressed to provide clear and concise findings. These key considerations include clarification on whether the research undertaken focuses on the late or long term effects of paediatric cancer treatment, taking a consistent approach to data analysis with the aim to improve the validity of the study findings, utilising a mixed methodology to gain further depth to the findings as well as increasing the number of studies that focus on a specific tumour type rather than numerous types to allow a detailed study to be undertaken into the potential late effects a treatment for a specific tumour may elicit.

DISCUSSION

If these key considerations are taken into account when conducting further research within this field, it would enable consistent findings to be utilised in providing the optimum educational provision for survivors of paediatric cancer who remain within the education system.

Modifiable risk factors for neurocognitive and psychosocial problems after Hodgkin lymphoma

Long-term survivors of childhood Hodgkin lymphoma (HL) experience a high burden of chronic health morbidities. Correlates of neurocognitive and psychosocial morbidity have not been well established. A total of 1760 survivors of HL (mean ± SD age, 37.5 ± 6.0 years; time since diagnosis, 23.6 ± 4.7 years; 52.1% female) and 3180 siblings (mean age, 33.2 ± 8.5 years; 54.5% female) completed cross-sectional surveys assessing neurocognitive function, emotional distress, quality of life, social attainment, smoking, and physical activity. Treatment exposures were abstracted from medical records. Chronic health conditions were graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 4.3 (1 = mild, 2 = moderate, 3 = severe/disabling, and 4 = life-threatening). Multivariable analyses, adjusted for age, sex, and race, estimated relative risk (RR) of impairment in survivors vs siblings and, among survivors, risk of impairment associated with demographic, clinical, treatment, and grade 2 or higher chronic health conditions. Compared with siblings, survivors had significantly higher risk (all, P < .05) of neurocognitive impairment (eg, memory, 8.1% vs 5.7%), anxiety (7.0% vs 5.4%), depression (9.1% vs 7%), unemployment (9.6% vs 4.4%), and impaired physical/mental quality of life (eg, physical function, 11.2% vs 3.0%). Smoking was associated with a higher risk of impairment in task efficiency (RR, 1.56; 95% confidence interval [CI], 1.02-2.39), emotional regulation (RR, 1.84; 95% CI, 1.35-2.49), anxiety (RR, 2.43; 95% CI, 1.51-3.93), and depression (RR, 2.73; 95% CI, 1.85-4.04). Meeting the exercise guidelines of the Centers for Disease Control and Prevention was associated with a lower risk of impairment in task efficiency (RR, 0.70; 95% CI, 0.52-0.95), organization (RR, 0.60; 95% CI, 0.45-0.80), depression (RR, 0.66; 95% CI, 0.48-0.92), and multiple quality of life domains. Cardiovascular and neurologic conditions were associated with impairment in nearly all domains. Survivors of HL are at elevated risk for neurocognitive and psychosocial impairment, and risk is associated with modifiable factors that provide targets for interventions to improve long-term functional outcomes.

Recommendations for the surveillance of education and employment outcomes in survivors of childhood, adolescent, and young adult cancer: A report from the International Late Effects of Childhood Cancer Guideline Harmonization Group

Educational achievement and employment outcomes are critical indicators of quality of life in survivors of childhood, adolescent, and young adult (CAYA) cancer. This review is aimed at providing an evidence-based clinical practice guideline (CPG) with internationally harmonized recommendations for the surveillance of education and employment outcomes in survivors of CAYA cancer diagnosed before the age of 30 years. The CPG was developed by a multidisciplinary panel under the umbrella of the International Late Effects of Childhood Cancer Guideline Harmonization Group. After evaluating concordances and discordances of 4 existing CPGs, the authors performed a systematic literature search through February 2021. They screened articles for eligibility, assessed quality, and extracted and summarized the data from included articles. The authors formulated recommendations based on the evidence and clinical judgment. There were 3930 articles identified, and 83 of them, originating from 17 countries, were included. On a group level, survivors were more likely to have lower educational achievement and more likely to be unemployed than comparisons. Key risk factors for poor outcomes included receiving a primary diagnosis of a central nervous system tumor and experiencing late effects. The authors recommend that health care providers be aware of the risk of educational and employment problems, implement regular surveillance, and refer survivors to specialists if problems are identified. In conclusion, this review presents a harmonized CPG that aims to facilitate evidence-based care, positively influence education and employment outcomes, and ultimately minimize the burden of disease and treatment-related late adverse effects for survivors of CAYA cancers. LAY SUMMARY: A multidisciplinary panel has developed guidelines for the surveillance of education and employment outcomes among survivors of childhood, adolescent, and young adult cancer. On the basis of evidence showing that survivors are at risk for lower educational achievement and unemployment, it is recommended that all survivors receive regular screening for educational and employment outcomes.

Long-Term Follow-Up of Pediatric CNS Tumor Survivors—A Selection of Relevant Long-Term Issues

Introduction: Survivors of pediatric central nervous system (CNS) tumors are at high risk for late effects and long-term morbidity. The quality of survival became increasingly important, as advances in diagnostics, multimodal treatment strategies, and supportive care have led to significant increases in long-term survival. Aim: This review aims to provide a global overview of the potential late effects and long-term follow-up care of CNS tumor survivors, directed to trainees and practitioners with less targeted training in pediatric oncology. Late effects in CNS tumor survivors: A specific focus on CNS tumor survivors relies on cognitive and psychosocial late effects, as they may have an impact on education, professional career, independent living, and quality of life. Further important late effects in CNS tumor survivors include endocrine, metabolic, cardiovascular, and cerebrovascular diseases. Conclusions: Comprehensive long-term follow-up care is essential for pediatric CNS tumor survivors to improve their quality of survival and quality of life. An individualized approach, taking all potential late effects into account, and carried out by an interdisciplinary team, is recommended, and should continue into adulthood. Existing recommendations and guidelines on long-term follow-up care guide the multidisciplinary teams.

Educational Attainment and Employment Outcome of Survivors of Pediatric CNS Tumors in Switzerland-A Report from the Swiss Childhood Cancer Survivor Study

Background: Childhood cancer survivors diagnosed with a central nervous system (CNS) tumor are at risk for educational and vocational challenges. This study compared educational attainment and employment outcome in survivors of CNS tumors to survivors of other malignancies. Methods: The questionnaire-based Swiss Childhood Cancer Survivor Study (SCCSS) included cancer patients diagnosed between 1976 and 2010, aged ≤20 years, who survived ≥5 years after diagnosis. We classified participants aged ≥16 years into three groups: CNS tumor and non-CNS malignancy with and without CNS-directed treatment. We analyzed educational attainment, employment outcome and special schooling. Subgroup analyses included survivors aged ≥25 years. Results: We analyzed 2154 survivors, including 329 (15%) CNS tumor survivors, 850 (40%) non-CNS tumor survivors with and 975 (45%) without CNS-directed treatment. Fewer CNS tumor survivors aged ≥25 years reached tertiary education (44%) compared to those without CNS-directed treatment (51%) but performed similar to survivors with CNS-directed treatment (42%). Among CNS tumor survivors, 36 (14%) received special schooling. Higher parental education was associated with higher levels in survivors. Employment outcome did not significantly differ between the three diagnostic groups. A higher proportion of CNS tumor survivors received disability pension or were unemployed. Conclusions: Our findings suggest that CNS tumor survivors need more time to achieve their highest educational level. This should influence clinical care of these survivors by offering vocational counseling.

Central nervous system tumors in children under 5 years of age: a report on treatment burden, survival and long-term outcomes

Purpose

The challenges of treating central nervous system (CNS) tumors in young children are many. These include age-specific tumor characteristics, limited treatment options, and susceptibility of the developing CNS to cytotoxic therapy. The aim of this study was to analyze the long-term survival, health-related, and educational/occupational outcomes of this vulnerable patient population.

Methods

Retrospective study of 128 children diagnosed with a CNS tumor under 5 years of age at a single center in Switzerland between 1990 and 2019.

Results

Median age at diagnosis was 1.81 years [IQR, 0.98–3.17]. Median follow-up time of surviving patients was 8.39 years [range, 0.74–23.65]. The main tumor subtypes were pediatric low-grade glioma (36%), pediatric high-grade glioma (11%), ependymoma (16%), medulloblastoma (11%), other embryonal tumors (7%), germ cell tumors (3%), choroid plexus tumors (6%), and others (9%). The 5-year overall survival (OS) was 78.8% (95% CI, 71.8–86.4%) for the whole cohort. Eighty-seven percent of survivors > 5 years had any tumor- or treatment-related sequelae with 61% neurological complications, 30% endocrine sequelae, 17% hearing impairment, and 56% visual impairment at last follow-up. Most patients (72%) attended regular school or worked in a skilled job at last follow-up.

Conclusion

Young children diagnosed with a CNS tumor experience a range of complications after treatment, many of which are long-lasting and potentially debilitating. Our findings highlight the vulnerabilities of this population, the need for long-term support and strategies for rehabilitation, specifically tailored for young children.

Factors related to employment in childhood cancer survivors in Japan: A preliminary study

PURPOSE

Previous research has revealed vocational and academic difficulties in childhood cancer survivors, and explored impact of survivors' medical history and physical function on vocational and academic status. However, we often encounter survivors with similar diagnoses and late effects but different academic or employment statuses. This raises the question of what affects academic attainment and employment other than treatment or late effects. This study aimed to explore factors associated with childhood cancer survivors' employment status and academic achievement.

METHODS

Comprehensive health check-up and questionnaire survey were conducted for 69 survivors who were over the age of 18 and participated in St. Luke's Lifetime cohort study. We obtained survivors' biological function using comprehensive health check-up, neurocognitive states, quality of life, transition readiness, and family function. We conducted univariate analysis (Mann-Whitney U tests or chi-square tests) to compare the differences between the regular workers/students and non-regular workers/unemployed groups. The variables with p-values <0.1 were used as independent variables multivariate logistic regression to explore predictors of employment status and academic attainment.

RESULTS

Result of the univariate analysis, intelligence quotient, SF-8 PCS, transition readiness, family function were used for multivariate logistic regression as independent variables. The stepwise likelihood method was conducted; intelligence quotient (odds ratio [OR] = 1.100; 95% confidence interval [CI] 1.015-1.193; p = 0.021), transition readiness (OR = 0.612; 95% CI 0.396-0.974; p = 0.038), and family function (OR = 2.337; 95% CI 1.175-4.645; p = 0.015) were found to be associated with survivors' regular workers/students in the final regression model.

CONCLUSION

Long-term follow-up of pediatric cancer survivors requires the provision of total care, which supports physical, psychological, and social functions to improve health, readiness for transition to self-management, and family functioning.

Help-seeking behaviour and attitudes towards internet-administered psychological support among adolescent and young adults previously treated for cancer during childhood: protocol for a survey and embedded qualitative interview study in Sweden

INTRODUCTION

A subgroup of adolescent and young adult childhood cancer survivors (AYACCS) are at increased risk of psychological distress. Despite this, AYACCS experience difficulties accessing psychological support. E-mental health (e-MH) may offer a solution to reduce this treatment gap. However, research examining e-MH for AYACCS has experienced difficulties with recruitment, retention and adherence. Such difficulties may relate to: (1) help-seeking behaviour and/or (2) e-MH acceptability. The overall study aims are to: (1) examine potential associations between health service use factors, informed by Andersen's behavioural model of health services use, and help-seeking behaviour; (2) examine attitudes towards e-MH interventions; and (3) explore perceived need for mental health support; past experience of receiving mental health support; preferences for support; and barriers and facilitators to help-seeking.

METHODS AND ANALYSIS

An online and paper-based cross-sectional self-report survey (98 items) and embedded qualitative interview study across Sweden, with a target sample size of n=365. Participants are aged 16-39 years, diagnosed with cancer when 0-18 years and have completed successful cancer treatment. The survey examines sociodemographic and clinical characteristics, actual help-seeking behaviour, attitudes towards e-MH, stigma of mental illness, mental health literacy, social support and current symptoms of depression, anxiety, and stress. Survey respondents with past and/or current experience of mental health difficulties are invited into the qualitative interview study to explore: (1) perceived need for mental health support; (2) past experience of receiving mental health support; (3) preferences for support; and (4) barriers and facilitators to help-seeking. Potential associations between health service use factors and help-seeking behaviour are examined using univariable and multivariable logistic regressions. Qualitative interviews are analysed using content analysis.

Social-ecological predictors of school functioning in Hispanic children treated for cancer with central nervous system-directed therapies

BACKGROUND

Children with brain tumor or acute leukemia are at risk for neurotoxic side effects associated with their cancer therapies. These long-term deficits include poor health-related quality of life (HRQOL) in school and lower educational achievement. Although social-ecological factors may impact these outcomes, it is not known which factors play a role. Our objective was to evaluate the factors affecting school HRQOL in Hispanic childhood cancer survivors, an important at-risk group.

PROCEDURE

Multivariable regression analyses examined whether selected social-ecological factors contribute toward suboptimal school HRQOL in 73 Hispanic children treated with central nervous system (CNS)-directed cancer therapies after accounting for effects associated with established cancer-related risk factors.

RESULTS

Consistent with expectations from prior research, in our multivariate analysis, the cancer-related factors of having a brain tumor diagnosis and being younger at cancer diagnosis were significant predictors of reduced parent-reported school HRQOL (F(2,65) = 5.46, P < .01) and accounted for 14% of the variance. Adding the social-ecological variables of parent education, child motivation, and parental knowledge accounted for an additional 25% of the variance in school HRQOL, where higher levels were associated with better child school HRQOL. Parenting knowledge was a contributor even after controlling for effects associated with the other variables in the model (F(1,62) = 4.88, P < .05).

CONCLUSIONS

Cancer survivorship care should incorporate parent education interventions to enhance the child's school functioning, particularly for Hispanic childhood cancer survivors from predominantly Spanish-speaking families. Future research should consider other at-risk groups and incorporate social-ecological indicators to predict HRQOL outcomes.

News on immune checkpoint inhibitors as immunotherapy strategies in adult and pediatric solid tumors

Immune checkpoint inhibitors (ICIs) have shown unprecedented benefits in various adult cancers, and this success has prompted the exploration of ICI therapy even in childhood malignances. Although the use of ICIs as individual agents has achieved disappointing response rates, combinational therapies are likely to promise better results. However, only a subset of patients experienced prolonged clinical effects, thus suggesting the need to identify robust bio-markers that predict individual clinical response or resistance to ICI therapy as the main challenge. In this review, we focus on how the use of ICIs in adult cancers can be translated into pediatric malignances. We discuss the physiological mechanism of action of each IC, including PD-1, PD-L1 and CTLA-4 and the new emerging ones, LAG-3, TIM-3, TIGIT, B7-H3, BTLA and IDO-1, and evaluate their prognostic value in both adult and childhood tumors. Furthermore, we offer an overview of preclinical models and clinical trials currently under investigation to improve the effectiveness of cancer immunotherapies in these patients. Finally, we outline the main predictive factors that influence the efficacy of ICIs, in order to lay the basis for the development of a pan-cancer immunogenomic model, able to direct young patients towards more specific immunotherapy.

Enduring psychological impact of childhood cancer on survivors and their families in Ireland: A national qualitative study

Objective

To establish the major expressed psychological needs of adult survivors of childhood cancer living in Ireland.

Methods

Seven focus groups were conducted with adult survivors of childhood cancer and their parents in 2018. Survivors were invited to participate if they were diagnosed with cancer before age 18.

Results

Thirty‐three participants (15 survivors, 18 parents; 27 female, 6 male) were included. They had experienced a range of haematological and solid tumours. Five themes were generated: (a) Enduring psychological impact on survivors; many survivors experience delayed trauma and mental health crises in adulthood. (b) Enduring psychological impact on family members; parents and siblings have unmet psychological needs relating to the family's experience of cancer. (c) Enduring impact on family dynamics; survivors and parents expressed fear and guilt relating to cancer which impacted on family interactions. (d) Challenges accessing support; psychological support services are inadequate to meet expressed needs. (e) Desired model of care; no single service model appeals to all survivors, and flexibility is required in the delivery of psychological support.

Conclusion

Adult survivors of childhood cancer and their family members experience enduring psychological effects relating to their diagnosis and treatment. Psychological support services are inadequate to meet the expressed needs of this growing population.

Childhood cancer: Survival, treatment modalities, late effects and improvements over time

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.

Educational attainment in childhood cancer survivors: a meta-analysis

OBJECTIVE

To assess differences across educational outcomes in survivors of childhood cancer (CCS) compared with peers.

DESIGN

Systematic review and meta-analysis of observational studies.

DATA SOURCES AND STUDY SELECTION

Medline, EMBASE, ERIC, CINAHL and PsycInfo from inception to 1st August 2018. Any peer reviewed, comparative study with a population of any survivor of childhood cancer, from high-economy countries, reporting outcomes on educational attainment, were selected.

RESULTS

26 studies representing 28 434 CCS, 17 814 matched controls, 6582 siblings and six population studies from 11 high-income countries, which have similar access to education and years of mandatory schooling as reported by the Organisation for Economic Cooperation and Development, were included. CCS were more likely to remain at compulsory level (OR 1.36, 95% CI 1.26 to 1.43) and less likely to complete secondary (OR 0.93, 95% CI 0.87 to 1.0) and tertiary level education (OR 0.87, 95% CI 0.78 to 0.98). They were more likely to require special educational needs (OR 2.47, 95% CI 1.91 to 3.20). Subgroup analyses revealed that survivors, irrespective of central nervous system (CNS) involvement, were less likely to progress onto secondary level compared with cancer-free peers (OR 1.77. 95% CI 1.46 to 2.15; OR 1.19, 95% CI 1.00 to 1.42, respectively). This, however, changed at tertiary level where those with CNS involvement continued to perform worse (OR 0.61, 95% CI 0.55 to 0.68) but those without appeared to perform similarly to their peers (OR 1.12, 95% CI 1.0 to 1.25).

CONCLUSIONS

Compared with controls, we have elucidated significant differences in educational attainment in survivors. This is sustained across different countries, making it an international issue. CNS involvement plays a key role in educational achievement. Clinicians, teachers and policymakers should be made aware of differences and consider advocating for early educational support for survivors.

Social Inequalities Along the Childhood Cancer Continuum: An Overview of Evidence and a Conceptual Framework to Identify Underlying Mechanisms and Pathways

Inequalities in health according to social conditions are regarded as unnecessary and unjust. There is a large body of evidence on inequalities in adult cancer, observable throughout the societies on a national level as well as on a global scale. Socioeconomic influences on health matter at all ages including childhood, for which childhood cancer is the leading cause of disease related death in high-income countries (HICs). Substantial differences in the reported incidence of childhood cancers have been observed globally by socioeconomic development of a population. This is reflected in the higher incidence rates reported for HICs, particularly for acute lymphoblastic leukemia, and for cancer in infants (below 1 year), compared to low- and middle-income countries (LMICs). Considerable inequalities between populations and degree of socioeconomic development are also noted for survival from childhood cancer, with substantially lower survival rates seen in most LMICs compared to HICs. With respect to inequalities by socioeconomic position (SEP) within countries, findings of an association between SEP and childhood cancer risk are diverse and limited to studies from HICs. On the contrary, observations on social inequalities in survival within countries are accumulating and indicate that survival inequalities do not only concern resource-poor countries but also high-income populations including European countries. In turn, a childhood cancer diagnosis in itself may have implications on the parents' socioeconomic situation as well as on the later socioeconomic life after having survived the disease. The underlying mechanisms and causal pathways of these empirically demonstrated social inequalities are poorly understood, although it is of significant public health relevance for any actions or strategies to reduce childhood cancer-related inequity. We propose a conceptual framework on potential underlying mechanism and pathways specifically addressing social inequalities in childhood cancer and after childhood cancer to (i) illustrate potential pathways by which social determinants may create health inequities at different points of the childhood cancer continuum; (ii) illustrate potential pathways by which a childhood cancer diagnosis may impact the socioeconomic situation of the concerned family or the later life of a childhood survivor; and (iii) point out how major determinants may relate to each other.

Prevalence of mental distress among adult survivors of childhood cancer in Germany-Compared to the general population

BACKGROUND

Increasing survival rates after childhood cancer have raised the issue of long-term mental health consequences in adulthood. This study determines mental health distress among long-term survivors of pediatric cancer and compares it to control groups.

METHODS

Childhood cancer survivors (CCS; N = 951, aged 24-49 years) were compared to three age-matched control groups from the general population collected at three time points. The study compared the prevalence of clinically relevant symptoms of a wide range of common mental disorders (depression, somatic distress, suicidal ideation, generalized anxiety, panic, social anxiety, and sleep disturbances) using identical, validated questionnaires. CCS were identified by the German Childhood Cancer Registry. Controls were approached by a demographic consultation company (USUMA) which assured that the three samples were nationally representative.

RESULTS

Childhood cancer survivors reported higher education than controls and were less often married. All forms of common mental distress were increased among survivors. Twenty-four percent of male (N = 526) and 41% of female survivors (N = 425) reported some form of clinically relevant mental health symptoms. Somatic distress as the leading complaint was highly frequent among CCS (OR: 10.98, CI 95%: 7.24-16.64). Complaints by generalized anxiety (OR: 5.04, CI 95%: 2.61-9.70), panic (OR: 3.28, CI 95%: 1.60-6.70), depression (OR: 3.36, CI 95%: 2.22-5.09), and suicidality (OR = 2.22; CI 95%: 1.38-3.57) were also strongly increased. Female sex, low education, low income, and unemployment were associated with increased distress.

CONCLUSIONS

Findings indicate a need to integrate psycho-oncological screening and care into long-term aftercare. Somatic distress, as cause and indicator of psychological distress, should receive stronger attention, especially tiredness, low energy, and pain.

Surviving childhood cancer: a systematic review of studies on risk and determinants of adverse socioeconomic outcomes

Substantial improvements in childhood cancer survival have resulted in a steadily increasing population of childhood cancer survivors. Whereas somatic late effects have been assessed in many studies, less is known about the impact of childhood cancer on socioeconomic outcomes in survivors. The aim of this article was to evaluate and summarise the evidence on the socioeconomic conditions of childhood cancer survivors and to identify survivors at particular risk of adverse socioeconomic outcomes. An extensive literature search of three electronic databases was conducted. Of 419 articles identified, 52 met the inclusion criteria. All the selected articles were appraised for quality, and findings were summarised in a narrative synthesis. Childhood cancer survivors were at higher risk of adverse socioeconomic outcomes with regard to educational achievement, income and social security benefits than the general population or a sibling comparison group. The risks for unemployment and a lower occupational position were significantly increased only for survivors of a central nervous system tumour. Notably, survivors of central nervous system tumours, survivors treated with cranial radiotherapy and those diagnosed at younger age independent of cancer type were determinants of particular adverse socioeconomic outcomes. Given the increasing population of childhood cancer survivors, targeted follow-up interventions and support strategies addressing not only the somatic and psychiatric late effects but also the socioeconomic difficulties that some childhood cancer survivors face is of high importance to reduce social inequity, and ensure a high quality of life after childhood cancer.

The Population Impact of Childhood Health Conditions on Dropout from Upper-Secondary Education

OBJECTIVES

To quantify how large a part of educational dropout is due to adverse childhood health conditions and to estimate the risk of dropout across various physical and mental health conditions.

STUDY DESIGN

A registry-based cohort study was conducted on a 20% random sample of Finns born in 1988-1995 (n = 101 284) followed for school dropout at ages 17 and 21. Four broad groups of health conditions (any, somatic, mental, and injury) and 25 specific health conditions were assessed from inpatient and outpatient care records at ages 10-16 years. We estimated the immediate and more persistent risks of dropout due to health conditions and calculated population-attributable fractions to quantify the population impact of childhood health on educational dropout, while accounting for a wide array of sociodemographic confounders and comorbidity.

RESULTS

Children with any health condition requiring inpatient or outpatient care at ages 10-16 years were more likely to be dropouts at ages 17 years (risk ratio 1.71, 95% CI 1.61-1.81) and 21 years (1.46, 1.37-1.54) following adjustment for individual and family sociodemographic factors. A total of 30% of school dropout was attributable to health conditions at age 17 years and 21% at age 21 years. Mental disorders alone had an attributable fraction of 11% at age 21 years, compared with 5% for both somatic conditions and injuries. Adjusting for the presence of mental disorders reduced the effects of somatic conditions.

CONCLUSIONS

More than one fifth of educational dropout is attributable to childhood health conditions. Early-onset mental disorders emerge as key targets in reducing dropout.

Socioeconomic Factors and Ninth Grade School Performance in Childhood Leukemia and CNS Tumor Survivors

Background

Childhood cancer survivors can experience deficits in school performance in adolescence. Few studies have investigated how social and socioeconomic factors influence and modify school performance. This study investigates the hypothesis that social and parental socioeconomic factors influence ninth grade school performance in childhood leukemia and central nervous system (CNS) tumor survivors and that the effect is different from that in healthy peers.

Methods

We analyzed data from nationwide Danish registers on school grades for children who finished ninth grade during 2002–2015 in Denmark. Using a unique within-school matched design, we compared grades from childhood cancer survivors with grades from healthy peers. Social factors were maternal/paternal civil status, immigrant status, and country of origin. Parental socioeconomic factors were measured by education and income. The study consisted of 36 426 children, of whom 460 and 289 were leukemia and CNS tumor survivors, respectively.

Results

School grades varied considerably across social strata. However, the grades among CNS tumor survivors varied notably less in the following effect modifiers: parental educational attainment, income, and immigrant status. On the contrary, no significant effect modifiers were found among leukemia survivors as compared with healthy peers.

Conclusion

There is a strong effect of social and parental socioeconomic factors on school performance in healthy adolescence in Denmark. The same pattern is seen in survivors of leukemia, but a different pattern is seen in survivors of CNS tumors. This finding suggests that impairment of school-related functions differ between leukemia and CNS tumor survivors. This study contributes to knowledge on learning in adolescence in childhood cancer survivors by investigating several social and socioeconomic effect modifiers with nationwide register data and a unique statistical method particularly suitable for comparing school grades. Improved insight could make it possible to identify high-risk groups that may need different means of help.

Surviving a childhood cancer: impact on education and employment

Long-term consequences of childhood cancer encompass adverse psychosocial effects that may severely limit the opportunity to live a satisfying and productive life. We assessed the social integration of adults cured of a cancer in their first 14 years of life by record linkage between the population-based Childhood Cancer Registry of Piedmont and the Turin Longitudinal Study. We compared education and employment outcomes within the cohort of survivors and between the cohort of survivors and their peers in the general population through logistic regression. Individuals cured of a childhood tumour have a higher risk of not obtaining educational qualifications [odds ratio (OR) 0.67 (95% confidence interval 0.40-1.11) for compulsory school, OR 0.81 (0.61-1.07) for higher education] or employment, OR 0.66 (0.45-0.98), than the general population. This problem is particularly severe for individuals cured of a central nervous system neoplasm: OR 0.56 (0.31-1.01) for higher education and OR 0.28 (0.13-0.58) for employment. Within-cohort comparisons show that men are less likely to obtain educational goals than women, OR 0.72 (0.40-1.29), but more likely to be employed, OR 2.18 (0.90-5.28); parental education (university qualifications) is positively associated with the success of the child's education, OR 9.54 (2.60-35.02), but not with their employment status, OR 1.02 (0.21-4.85). Strategies should be put in place to mitigate the risk of adverse psychosocial effects from the beginning of treatment to cure and beyond to offer those suffering a cancer at a young age the possibility of full integration into society.

Factors influencing risk-based care of the childhood cancer survivor in the 21st century

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

The efficacy of cognitive interventions for improving cognitive performance and academic achievement in children after cancer treatment: A systematic review

Academic decline has been reported in children after cancer treatment, believed to be as a result of cognitive impairment. Cognitive interventions may improve both the present and future outcomes for children after cancer treatment by improving cognitive and/or academic performance. This review aimed to examine the efficacy of cognitive interventions in children who had received cancer treatment. A systematic search of the PsycInfo and PubMed databases was conducted in May 2015 to identify studies in which cognitive interventions were conducted with children who had undergone cancer treatment and were under the age of 21. Cognitive or academic outcomes needed to be reported pre- and post-intervention to meet the inclusion criteria. Eleven studies were included in this review. Computerized and home-based cognitive interventions were found to be most successful at improving cognitive skills. However, few cognitive interventions assessed academic achievement specifically. Future cognitive intervention research studies should include measures of academic achievement outcomes, because academic achievement and cognitive outcomes may differ. Future research regarding the effectiveness of early, home-based and computerized intervention is warranted.

The Impact of a Childhood Cancer Diagnosis on the Children and Siblings’ School Attendance, Performance, and Activities: A Qualitative Descriptive Study

Families of children with cancer are confronted with unexpected out-of-pocket expenses and productivity costs associated with the diagnosis. One productivity cost that falls on children is the impact of cancer on children’s school attendance, performance, and activities (eg, play, friendships, and socialization). Nested within the Childhood Cancer Cost Study, this qualitative descriptive study used convenience sampling to recruit and interview parents of children newly diagnosed with cancer. Content analysis techniques were used to inductively descriptive the semistructured interview data. Sixty-six parents of 65 children with cancer and of 73 siblings participated. The most commonly reported productivity loss in children with cancer was school absenteeism mainly due to cancer treatment. Children fell behind their classmates academically and lost important social time with peers. A few siblings also fell behind their peers primarily due to limited parental attention. Parents adopted various strategies to lessen the impact of the diagnosis on their children’s school attendance, performance, and activities. Providing parents with additional resources and support may optimize their children’s academic and social reintegration into school.

The State of Cellular Adoptive Immunotherapy for Neuroblastoma and Other Pediatric Solid Tumors

Research on adult cancer immunotherapy is proceeding at a rapid pace resulting in an impressive success rate exemplified by a few high profile cases. However, this momentum is not readily extended to pediatric immunotherapy, and it is not for lack of trying. Though reasons for the slower advance are not apparent, some issues can be raised. Pediatric cancer patients represent a distinct demographic group whose immune system is inherently different from that of mature adults. Treating pediatric patients with immunotherapy designed for adults may not yield objective clinical responses. Here, we will present an update on adoptive T-cell and natural killer-cell therapies for neuroblastoma and other childhood solid tumors. Additionally, we will delineate key differences between human fetal/neonatal and adult immune systems. We hope this will generate interests leading to the discussion of potential future directions for improving adoptive cancer immunotherapy for children.

Unemployment Following Childhood Cancer

BACKGROUND

Childhood cancer survivors are at risk of physical and mental long-term sequelae that may interfere with their employment situation in adulthood. We updated a systematic review from 2006 and assessed unemployment in adult childhood cancer survivors compared to the general population, and its predictors.

METHODS

Systematic literature searches for articles published between February 2006 and August 2016 were performed in CINAHL, EMBASE, PubMed, PsycINFO, and SocINDEX. We extracted unemployment rates in studies with and without population controls (controlled /uncontrolled studies). Unemployment in controlled studies was evaluated using a meta-analytic approach.

RESULTS

We included 56 studies, of which 27 were controlled studies. Approximately one in six survivors was unemployed. The overall meta-analysis of controlled studies showed that survivors were more likely to be unemployed than controls (Odds Ratio [OR] = 1.48, 95% confidence interval [CI]: [1.14; 1.93]). Elevated odds were found in survivors in the US and Canada (OR = 1.86, 95% CI: [1.26; 2.75]), as well as in Europe (OR = 1.39, 95% CI: [0.97; 1.97]). Survivors of brain tumors in particular were more likely to be unemployed (OR = 4.62, 95% CI: [2.56; 8.31]). Narrative synthesis across all included studies revealed younger age at study and diagnosis, female sex, radiotherapy, and physical late effects as further predictors of unemployment.

CONCLUSION

Childhood cancer survivors are at considerable risk of unemployment in adulthood. They may benefit from psycho-social care services along the cancer trajectory to support labor market integration.

Long-term Survivors of Childhood Brain Tumors: Impact on General Health and Quality of Life

PURPOSE OF REVIEW

We review and summarize the key issues affecting general health and quality of life (QOL) of pediatric long-term survivors of brain tumors.

RECENT FINDINGS

Long-term survivors of brain tumors are at risk of considerable late morbidity and mortality. Lengthening survival in brain tumors has highlighted the deep impact of tumor and its treatment on the physical, psychological, functional, and social health and QOL of these survivors. Evolution in tumor therapy including surgery, radiotherapy, and systemic therapies, etc., has the potential to mitigate this impact to some extent. Sensitization of health staff, policy makers, and the primary designers of clinical trials towards integration of QOL end points while measuring survival in brain tumor patients is the need of the hour. New developments in tumor therapeutics must not only provide quantitative gain but also improve the quality of survival in these long-term survivors. While majority of the issues presented pertain to survivorship in pediatric brain tumor population, similar challenges are likely to exist in young adults surviving brain tumors as well.

Parent perspectives on the educational barriers and unmet needs of children with cancer

Childhood cancer challenges academic success and school engagement, yet little research has described these hardships. This study documented parental perspectives of the educational barriers and unmet needs of youth treated for cancer (n = 102). Treatment-related physical sequelae were noted as common problems interfering with school attendance and engagement. One-fourth of parents reported worse academic performance since diagnosis; however, many never had their child evaluated (63.3%) or enacted formalized educational accommodations (55%). Findings reflect educational challenges across the continuum of cancer care and survivorship, and highlight the importance of education of school staff on both acute and long-term effects of cancer treatment.

Understanding the school experiences of children and adolescents with serious chronic illness: a systematic meta-review

BACKGROUND

Serious chronic illness can have a detrimental effect on school attendance, participation and engagement, leaving affected students at risk of failing to meet their developmental potential. An improved understanding of factors that help to explain or mitigate this risk can help educators and health professionals deliver the most effective support. This meta-review critiqued the available evidence examining the link between six chronic illnesses (asthma, cancer, chronic kidney diseases, heart diseases, cystic fibrosis and gastrointestinal diseases) and children's and adolescents' school experiences and outcomes, as well as investigating the medical, school, psychosocial and sociodemographic factors that are linked to poorer or better school outcomes.

METHODS

We searched CINAHL, Cochrane Database, EMBASE, ERIC, MEDLINE, ProQuest Theses and Dissertations, and PsycINFO (2000-2015). Systematic and narrative reviews, and meta-analyses, of original studies examining students' subjective school experiences and objective school outcomes were eligible. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria to critically appraise all systematic reviews. The Grading of Recommendations Assessment, Development, and Evaluation system guided our recommendations for practice and research.

RESULTS

Eighteen reviews of 172 studies including more than 40 000 students were eligible. Therefore, we chose to conduct a meta-review to provide an overview of the literature on the relationship between chronic illness and school experiences and outcomes. We also explored the associated medical, school, psychosocial and sociodemographic factors affecting the relationship between illness and school experiences and outcomes.

CONCLUSION

Students with chronic illness demonstrate mixed school experiences and outcomes that are often worse than students without chronic illness. Modifiable factors, such as students' engagement with school, may be novel yet appropriate targets of educational support to ensure that these students reach their full schooling potential.

Health-related quality of life in parents of pediatric brain tumor survivors at the end of tumor-directed therapy

OBJECTIVE

This study examines theoretical covariates of health-related quality of life (HRQL) in parents of pediatric brain tumor survivors (PBTS) following completion of tumor-directed therapy.

METHODS

Fifty PBTS (ages 6-16) completed measures of neurocognitive functioning and their parents completed measures of family, survivor, and parent functioning.

RESULTS

Caregiving demand, caregiver competence, and coping/supportive factors were associated with parental physical and psychosocial HRQL, when controlling for significant background and child characteristics.

CONCLUSION

Study findings can inform interventions to strengthen caregiver competence and family functioning following the completion of treatment, which may improve both parent and survivor outcomes.

Educational and occupational outcomes of childhood cancer survivors 30 years after diagnosis: a French cohort study

Background:

Although survival from childhood cancer has increased, little is known on the long-term impact of treatment late effects on occupational attainment or work ability.

Methods:

A total of 3512 five-year survivors treated before the age of 19 years in 10 French cancer centres between 1948 and 2000 were identified. Educational level, employment status and occupational class of survivors were assessed by a self-reported questionnaire. These outcome measures were compared with sex–age rates recorded in the French population, using indirect standardisation. Paternal occupational class was also considered to control for the role of survivors' socioeconomic background on their achievement. Multivariable analyses were conducted to explore clinical characteristics associated with the outcomes.

Results:

A total of 2406 survivors responded to the questionnaire and survivors aged below 25 years were included in the current analysis. Compared with national statistics adjusted on age and sex, male survivors were more likely to be college graduates (39.2% vs 30.9% expected; P<0.001). This higher achievement was not observed either for leukaemia or central nervous system (CNS) tumour survivors. Health-related unemployment was higher for survivors of CNS tumour (28.1% vs 4.3% P<0.001) but not for survivors of other diagnoses. Survivors of non-CNS childhood cancer had a similar or a higher occupational class than expected.

Conclusions:

Survivors treated for CNS tumour or leukaemia, especially when treatment included cranial irradiation, might need support throughout their lifespan.

Harnessing the Immunotherapy Revolution for the Treatment of Childhood Cancers

Cancer immunotherapies can be classified into agents that amplify natural immune responses (e.g., checkpoint inhibitors) versus synthetic immunotherapies designed to initiate new responses (e.g., monoclonal antibodies [mAbs], chimeric antigen receptors [CARs]). Checkpoint inhibitors mediate unprecedented benefit in some adult cancers, but have not demonstrated significant activity in pediatric cancers, likely due their paucity of neoantigens. In contrast, synthetic immunotherapies such as mAbs and CAR T cells demonstrate impressive effects against childhood cancers. Intense efforts are underway to enhance the effectiveness of pediatric cancer immunotherapies through improved engineering of synthetic immunotherapies and by combining these with agents designed to amplify immune responses.

Employment status and occupational level of adult survivors of childhood cancer in Great Britain: The British childhood cancer survivor study

The British Childhood Cancer Survivor Study (BCCSS) provides the first detailed investigation of employment and occupation to be undertaken in a large population-based cohort. Previous studies have been limited by design issues such as using small numbers of survivors with specific diagnoses, and involved limited assessment of employment status and occupational level. The BCCSS includes 17,981 5-year survivors of childhood cancer. Employment status and occupational level were ascertained by questionnaire from eligible survivors (n = 14,836). Multivariate logistic regression was used to explore factors associated with employment and occupation, and to compare survivors to their demographic peers in the general population. Employment status was available for 10,257 survivors. Gender, current age, cancer type, radiotherapy, age at diagnosis and epilepsy were consistently associated with being: employed; unable to work; in managerial or non-manual occupations. Overall, survivors were less likely to be working than expected (OR (99% CI): 0.89 (0.81-0.98)), and this deficit was greatest for irradiated CNS neoplasm survivors (0.34 (0.28-0.41)). Compared to the general population, survivors were fivefold more likely to be unable to work due to illness/disability; the excess was 15-fold among CNS neoplasm survivors treated with radiotherapy. Overall survivors were less likely to be in managerial occupations than expected (0.85 (0.77-0.94)). However, bone sarcoma survivors were more likely to be in these occupations than expected (1.37 (1.01-1.85)) and also similarly for non-manual occupations (1.90 (1.37-2.62)). Survivors of retinoblastoma (1.55 (1.20-2.01)) and 'other' neoplasm group (1.62 (1.30-2.03)) were also more likely to be in non-manual occupations than expected.

Ninth grade school performance in Danish childhood cancer survivors

Background:

Childhood cancer survivors can experience learning problems resulting in lower-than-expected attained education as adults. It is unclear whether learning problems manifest already during adolescence.

Methods:

We analysed nationwide Danish registries on school grades for Danish children during 2001–2014. Applying a matched design we compared grades of childhood cancer survivors to children without cancer at ninth grade. We estimated grade differences by subject and its correlation to cancer site and age at diagnosis. The available statistical precision allowed for an analysis of more rare cancer sites.

Results:

The total study population was 793 332 children (mean age 15.24 years and 49.7% girls), of whom 1320 were childhood cancer survivors. Lower rank grades were seen in children with cancer in all school subjects but differed substantially according to cancer site. Most affected were survivors of central nervous system (CNS) tumours, neuroblastoma, lymphoma, leukaemia, other malignant neoplasm and germ-cell tumours. Survivors from other cancer types did not obtain lower grades. Lower rank grades were associated with young age at diagnosis.

Conclusions:

The effect of childhood cancer differed substantially between cancer sites. The largest effect was among survivors of CNS tumours and leukaemia diagnosed at a young age, suggesting an association with radiation therapy. However, the majority of cancer survivors fare well. Increasing awareness on children affected by cancer and special accommodations may help maximise the learning potential of those most affected.

Non-graduation after comprehensive school, and early retirement but not unemployment are prominent in childhood cancer survivors-a Finnish registry-based study

BACKGROUND

In order to assess neurocognitive and social outcomes after childhood cancer, we explored the educational and vocational attainments of Finnish survivors in comparison to matched population controls.

METHODS

From national registries, we identified survivors (n = 3243) born from 1960 to 1992 and aged below 16 at cancer diagnosis (years 1964-2009) as well as their controls (n = 16,215). Data on educational achievements, yearly income, employment status, and retirement were retrieved from Statistics Finland.

RESULTS

The median (range) age at study was 28 (17-50) years. The proportion of those with no education after comprehensive school was higher than controls for all the diagnostic groups: brain tumor (BT) (33.5 vs 23.0 %), solid tumor (ST) (25.0 vs 21.4 %), and leukemia/NHL (29.2 vs 23.1 %). Odds ratios (OR) for unemployment were not significantly elevated in any survivor group compared to controls, but OR for being retired was elevated in each survivor group (BT 14.8, ST 2.2, leukemia/NHL 4.0). Irradiation significantly increased that OR only in BT survivors. Leukemia/NHL survivors treated after 1992 had lower risk for early retirement (OR 0.6) compared to those diagnosed earlier.

CONCLUSIONS

Survivors had higher frequencies than controls for lacking further education after comprehensive school. Unemployment was not common, but risk for early retirement was significantly increased in each three survivor group.

IMPLICATIONS FOR CANCER SURVIVORS

Reassuring is that premature retirement was less common during the most recent treatment era. Screening and follow-up of psychosocial performance more effectively might be essential, and there is a need for studies on possibility for effective rehabilitation of the survivors.

Core deficits and quality of survival after childhood medulloblastoma: a review

Background

Medulloblastoma is the most common malignant central nervous system tumor in children. Treatment most often includes surgical resection, craniospinal irradiation, and adjuvant chemotherapy. Although survival has improved dramatically, the tumor and its treatments have devastating long-term side effects that negatively impact quality of survival (QoS). The objective was to review the literature on QoS following childhood medulloblastoma.

Methods

This narrative review is based on a Medline database search and examination of the reference lists of papers selected.

Results

Frequent problems after medulloblastoma treatment include medical complications, such as long-term neurological and sensory (hearing loss) impairments; endocrine deficits, including growth problems; and secondary tumors. Neurocognitive impairment is repeatedly reported, with decreasing cognitive performances over time. Although all cognitive domains may be affected, low processing speed, attention difficulties, and working memory difficulties are described as the core cognitive deficits resulting from both cerebellar damage and the negative effect of radiation on white matter development. Long-term psychosocial limitations include low academic achievement, unemployment, and poor community integration with social isolation. Important negative prognostic factors include young age at diagnosis, conventional craniospinal radiotherapy, presence of postoperative cerebellar mutism, and perioperative complications. The influence of environmental factors, such as family background and interventions, remains understudied.

Conclusion

Future studies should focus on the respective impact of radiation, cerebellar damage, genomic and molecular subgroup parameters, and environmental factors on cognitive and psychosocial outcomes. Long-term (probably lifelong) follow-up into adulthood is required in order to monitor development and implement timely, suitable, multi-disciplinary rehabilitation interventions and special education or support when necessary.

Risk of Adverse Health and Social Outcomes Up to 50 Years After Wilms Tumor: The British Childhood Cancer Survivor Study

Purpose

Survivors of Wilms tumor (WT) are at risk for adverse health and social outcomes but risks beyond 30 years from diagnosis remain uncertain. We investigated the risks of adverse outcomes among 5-year survivors of WT, in particular, those between 30 and 50 years from diagnosis.

Patients and Methods

The British Childhood Cancer Survivor Study includes 1,441 5-year survivors of WT. We investigated cause-specific mortality, risk of subsequent primary neoplasms (SPNs), and, for those who completed a questionnaire, the extent of smoking and drinking, educational achievement, health status, and health service use compared with the general population.

Results

Cumulative risk of death from all causes, excluding recurrence, increased substantially from 5.4% to 22.7% at 30 years and 50 years, respectively, after WT diagnosis—75% of excess deaths beyond 30 years from diagnosis were attributable to SPNs (50%) and cardiac diseases (25%). Digestive cancer, most frequently bowel, accounted for 41% of excess cancers beyond 30 years.

Conclusion

Between 30 and 50 years from diagnosis, survivors of WT are at a substantially increased risk of premature mortality, and 75% of excess deaths were accounted for by SPNs and cardiac diseases. Radiotherapy exposure was a risk factor for both outcomes. The proportion of patients with WT who are exposed to radiotherapy has reduced substantially in recent decades because of initiatives such as the SIOP WT 2001 clinical trial, which sought to reduce late effects; however, the majority of current survivors, who are at least 30 years from diagnosis, received radiotherapy. Surveillance of this group should focus on SPNs, in particular, bowel and breast cancers, and cardiac conditions.

Aspects of mental health dysfunction among survivors of childhood cancer

BACKGROUND

Some previous studies have reported that survivors of childhood cancer are at an increased risk of developing long-term mental health morbidity, whilst others have reported that this is not the case. Therefore, we analysed 5-year survivors of childhood cancer using the British Childhood Cancer Survivor Study (BCCSS) to determine the risks of aspects of long-term mental health dysfunction.

PROCEDURE

Within the BCCSS, 10 488 survivors completed a questionnaire that ascertained mental health-related information via 10 questions from the Short Form-36 survey. Internal analyses were conducted using multivariable logistic regression to determine risk factors for mental health dysfunction. External analyses were undertaken using direct standardisation to compare mental health dysfunction in survivors with UK norms.

RESULTS

This study has shown that overall, childhood cancer survivors had a significantly higher prevalence of mental health dysfunction for 6/10 questions analysed compared to UK norms. Central nervous system (CNS) and bone sarcoma survivors reported the greatest dysfunction, compared to expected, with significant excess dysfunction in 10 and 6 questions, respectively; the excess ranged from 4.4-22.3% in CNS survivors and 6.9-15.9% in bone sarcoma survivors. Compared to expected, excess mental health dysfunction increased with attained age; this increase was greatest for reporting 'limitations in social activities due to health', where the excess rose from 4.5% to 12.8% in those aged 16-24 and 45+, respectively. Within the internal analyses, higher levels of educational attainment and socio-economic classification were protective against mental health dysfunction.

CONCLUSIONS

Based upon the findings of this large population-based study, childhood cancer survivors report significantly higher levels of mental health dysfunction than those in the general population, where deficits were observed particularly among CNS and bone sarcoma survivors. Limitations were also observed to increase with age, and thus it is important to emphasise the need for mental health evaluation and services across the entire lifespan. There is evidence that low educational attainment and being unemployed or having never worked adversely impacts long-term mental health. These findings provide an evidence base for risk stratification and planning interventions.

Psychosocial Follow-Up in Survivorship as a Standard of Care in Pediatric Oncology

Childhood cancer survivors (CCS) have a high risk of medical late effects following cancer therapy. Psychosocial late effects are less often recognized. Many CCS do not receive long-term follow-up (LTFU) care, and those who do are rarely screened for psychosocial late effects. An interdisciplinary team conducted a systematic review of qualitative and quantitative studies to assess social, educational, vocational, psychological, and behavioral outcomes along with factors related to receipt of LTFU care. We propose that psychosocial screening be considered a standard of care in long-term follow-up care and that education be provided to promote the use LTFU care starting early in the treatment trajectory.
