Abstract
Bedtime digital media use (BDM) is linked to poor sleep and fatigue in many populations. Pediatric cancer patients have been observed to engage in BDM in clinical settings, but it is unknown whether BDM rates are higher in this population or how this impacts their sleep and fatigue during treatment and into survivorship. The goal of this study was to evaluate patterns of BDM and its relationship with sleep and fatigue in a sample of pediatric cancer survivors and to compare these patterns with children from their own family (i.e. siblings) and children from unaffected families (i.e. healthy matched controls and siblings of controls). Ninety-nine children (4 groups: 24 acute lymphoblastic leukemia survivors, 13 survivor siblings, 33 controls, 29 control siblings) ages 8-18 were recruited from a long-term survivor clinic at a large children's hospital and via community advertisements. Survivors were 2-7 years post-treatment (M = 4.80 years). Children's BDM was parent-reported. Children completed 7 consecutive days of sleep actigraphy and the PedsQL Multidimensional Fatigue Scale. Most survivors (66.67%) engaged in BDM; smartphones were the most common medium. BDM patterns were equivalent across survivors, their siblings, controls, and control siblings. Statistical trends suggested that BDM was associated with fewer minutes of sleep and greater fatigue for all children; these relationships were equivalent across groups. BDM was common among survivors, but usage was not different from their own siblings or compared to healthy control children and sibling pairs. This study underscores the importance of assessing bedtime digital media use in childhood cancer survivors, although other factors impacting sleep should be explored. Clinicians should emphasize established recommendations for healthy media use and sleep habits in pediatric oncology settings.

Abstract
OBJECTIVE/BACKGROUND Retinoblastoma is an ocular cancer diagnosed in early childhood. Previous research has indicated the impact of cancer treatment on sleep, but little is known about how sleep is impacted among survivors of retinoblastoma. The current study aimed to describe sleep habits of school-age survivors of retinoblastoma, to examine associations between sleep and quality of life, and to examine concordance between parent and child reports of sleep habits. PATIENTS/METHODS Sixty-nine survivors of retinoblastoma (Mage = 10.89, SD = 1.07, 50.7% female; 56.5% unilateral disease) and their caregivers participated, providing information on both self- and parent-reported sleep habits, quality of life, and demographic data. RESULTS Greater sleep concerns than national norms were reported by parents (bedtime resistance (t(58) = 2.69, p = .009), greater sleep onset delay (t(66) = 2.46, p = .017), shorter sleep duration (t(57) = 2.12, p = .038), increased daytime sleepiness (t(53) = 6.45, p= <.001)) and children (sleep location (t(61) = 2.39, p = .02), restless legs syndrome (t(62) = -2.21, p = .03), parasomnias (t(64) = 19.19, p=<.001)) . Both children and parents of children who received enucleation endorsed greater sleep concerns across several domains (e.g., electronic use before bed, sleep-disordered breathing). Child- and parent-reported sleep concerns were generally associated with decreased quality of life. Finally, child- and parent-report of sleep habits appeared generally consistent. CONCLUSIONS Survivors of retinoblastoma experience sleep difficulties. As such, assessment and targeted intervention is important to mitigate any effects on quality of life. Future research should examine sleep habits of survivors of retinoblastoma across cultures and developmental periods.

Abstract
Background Pediatric brain tumor (PBT) survivors are at risk for developing sleep disturbances. While in other pediatric populations sleep disturbance has been associated with worse cognitive functioning, it is unclear to what extent this relationship generalizes to PBT survivors. The aim of the current study was to assess the relationship between sleep disturbance and aspects of cognition, including sluggish cognitive tempo (SCT) as well as attention and working memory. Materials and Methods Eighty-three PBT survivors 6–18 years of age who were at least 3 months post-treatment were included in the present cross-sectional study. Level of sleep disturbance was measured as a composite score reflecting various sleep problems as rated by caregivers. Cognitive measures included caregiver-ratings of sluggish cognitive tempo and attention problems, as well as performance-based cognitive measures assessing attention and executive functioning. Hierarchical regression analysis was used to assess associations between sleep and cognition. Results Of all caregivers, 32.5% reported one or more sleep disturbances as “very/often true” and over 68% of caregivers rated at least one sleep-related item as “somewhat true.” Of all cognitive variables, scores were most frequently impaired for SCT (30%). A higher level of sleep disturbance was associated with worse SCT and parent-rated attention problems. Associations between sleep and performance-based cognitive measures assessing attention and working memory were not statistically significant. Conclusion Findings of the current study highlight the importance of further investigation into the relationship between sleep and cognition in PBT survivors, which may assist efforts to maximize cognitive outcome and health-related quality of life in PBT survivors. The current study additionally suggests further investigation of SCT in this population is warranted, as it may be more sensitive to detecting possible associations with sleep disturbance relative to discrete measures that assess cognitive performance under ideal circumstances.

Abstract
Background Tumors of the central nervous system (CNS) are the most common solid childhood malignancy. Over the last decades, treatment developments have strongly contributed to the improved overall 5-year survival rate, which is now approaching 75%. However, children now face significant long-term morbidity with late-effects including sleep disorders that may have detrimental impact on everyday functioning and quality of life. The aims of this study were to (1) describe the symptoms that lead to polysomnographic evaluation; (2) describe the nature of sleep disorders diagnosed in survivors of childhood CNS tumor using polysomnography (PSG); and (3) explore the association between tumor location and diagnosed sleep disorder. Methods An extensive literature search following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines (PRISMA) was conducted. Inclusion criteria were children and adolescents diagnosed with a CNS tumor age <20 years having a PSG performed after end of tumor treatment. The primary outcome was sleep disorder confirmed by PSG. Results Of the 1,658 studies identified, 11 met the inclusion criteria. All the included articles were appraised for quality and included in the analysis. Analyses indicated that sleep disorders commonly occur among childhood CNS tumor survivors. Symptoms prior to referral for PSG were excessive daytime sleepiness (EDS), fatigue, irregular breathing during sleep and snoring. The most common sleep disorders diagnosed were sleep-related breathing disorders (i.e., obstructive sleep apnea) and central disorders of hypersomnolence (i.e., narcolepsy). Conclusion Our findings point to the potential benefit of systematically registering sleep disorder symptoms among CNS tumor patients together with tumor type and treatment information, so that at-risk patients can be identified early. Moreover, future rigorous and larger scale controlled observational studies that include possible modifiable confounders of sleep disorders such as fatigue and obesity are warranted.

Abstract
OBJECTIVES This study provided information about sleep disruption, particularly its prevalence and severity among Hong Kong Chinese childhood cancer survivors. Additionally, we identified the factors influencing sleep disruption and explored how fatigue, depressive symptoms and physical activity (PA) affect sleep disruption. METHODS 402 survivors 6-18 years old and 50 age- and gender-matched healthy counterparts were assessed for depressive symptoms, fatigue, PA and subjective sleep quality. Demographic and clinical information were collected. Multiple logistic regression analyses were conducted to identify any factors contributing to poor sleep. RESULTS Mean scores of depressive symptoms, fatigue for children and that for adolescents, and PA in survivors were 16.1 (SD=11.1), 24.6 (SD=10.3), 27.7 (SD=7.8) and 3.08 (SD=2.9), respectively. 44.8% of the survivors were poor sleepers, which was more that in healthy counterparts. The three most common sleep problem were prolonged sleep latency (31.9%), daytime dysfunction (23.4%) and sleep disturbance (22.9%). The time since last treatment (children: AOR=0.54, 95%CI=0.30-0.96, p=.04; adolescents: AOR=0.80, 95%CI=0.70-0.92, p<.01) and PA levels (children: AOR=0.46, 95%CI=0.260-0.82, p=.01; adolescents: AOR=0.70, 95%CI=0.49-0.98, p=.04) were negatively associated with sleep disruption, while depressive symptoms (children: AOR=1.31, 95%CI=1.04-1.64, p=.02; adolescents: AOR=1.07, 95%CI=1.01-1.13, p=.03), fatigue (children: AOR=1.15, 95% CI=1.00-1.31, p=.04; adolescents: AOR=1.08, 95%CI=1.02-1.15, p=.01), number of treatment received (children:AOR=16.56, 95% CI=1.27-216.82, p=.03; adolescents: AOR=7.30, 95%CI=2.36-22.56, p<.01) and co-sleeping (children: AOR=29.19, 95%CI=1.65-511.57, p=.02; adolescents: AOR=4.63, 95%CI=1.22-17.61, p=.02) were positively associated with sleep disruption. CONCLUSION PA made the largest contribution to reduce sleep disruption. It is crucial to advocate for the adoption and maintenance of PA in survivorship. This article is protected by copyright.

Abstract
BACKGROUND Previous research has demonstrated that paediatric cancer survivors (PCS) have lower sleep quality than their healthy peers. However, the research to date has focused mainly on self-reported data. Therefore, the aim of this cross-sectional study was to characterise selected sleep parameters in PCS using objective monitoring techniques and to compare them with a control group (CG) of their healthy peers during a structured recovery stay. A specific objective was to characterise sleep with respect to gender, age, and cancer type. METHODS 26 PCS and 38 CG aged 7-15 years participated in the study. Selected sleep indicators (time in bed, total sleep time, sleep efficiency) were objectively assessed with an Actigraph wGT3X-BT accelerometer for 12 days during the recovery stay. RESULTS No significant differences were found between the PCS and CG groups in terms of the selected sleep parameters. The total time in bed was 543.1 min/day in the PCS and 537.2 min/day in the CG (p=0.91). The total sleep time was 455.3 min/day in the PCS and 457.5 min/day in the CG (p=0.57). Sleep efficiency was 85.3% in the PCS and 86.3% in the CG (p=0.36). Sleep efficiency >85% was achieved by 62% of the PCS (n=16) and 68% of the CG (n=26). There were no significant differences in sleep parameters in terms of variables such as gender, age, or cancer type. CONCLUSION The results of our study suggest that - under the same conditions - the PCS did not differ from their healthy peers in terms of the indicators of time in bed, total sleep time, and sleep efficiency. No significant differences according to age, gender, or cancer type were found.

Abstract
Sleep disturbances represent an understudied yet common source of distress among pediatric cancer patients and survivors, with deleterious effects on quality of life. Sleep issues stem from multiple risk factors, yet individual contributors are difficult to isolate, consequently impeding the identification of targets for intervention. In many pediatric cancer patients, disrupted sleep and its negative impact on quality of life continue into adulthood and may affect various functional domains. This literature review highlights the types and prevalence of sleep disturbances in pediatric cancer patients during active treatment and through survivorship. Potential etiological and risk factors for disturbed sleep are summarized, including the effects of cancer and its treatment, psychosocial and family factors, as well as individual-patient aspects, such as genetics, mood and coping skills. While existing assessment and management strategies are reviewed, the literature is incomplete, and significant gaps emerge in our understanding of sleep disturbances in pediatric cancer patients and survivors. The review concludes with recommendations of areas where further research is needed. The aims of this review include increasing clinicians' awareness of sleep disturbances as a significant source of poor quality of life in pediatric cancer patients and survivors and directing researchers to gaps in our understanding of sleep disturbances in pediatric cancer patients and survivors.

Abstract
Background Sleep disruption is a prevalent symptom reported by survivors of childhood cancer. However, there is no validated instrument for assessing this symptom in this population group. To bridge the literature gap, this study translated and adapted the Pittsburgh Sleep Quality Index (PSQI) for Hong Kong Chinese cancer survivors and examined its psychometric properties and factor structure. Methods A convenience sample of 402 Hong Kong Chinese childhood cancer survivors aged 6–18 years were asked to complete the Chinese version of the PSQI, Center for Epidemiologic Studies Depression Scale for Children (CES-DC), Fatigue Scale-Child (FS-C)/Fatigue Scale-Adolescent (FS-A), and Pediatric Quality of Life Inventory (PedsQL). To assess known-group validity, 50 pediatric cancer patients and 50 healthy counterparts were recruited. A sample of 40 children were invited to respond by phone to the PSQI 2 weeks later to assess test–retest reliability. A cutoff score for the translated PSQI used with the survivors was determined using receiver operating characteristic analysis. Results The Chinese version of the PSQI had a Cronbach alpha of 0.71, with an intraclass correlation coefficient of 0.90. Childhood cancer survivors showed significantly lower mean PSQI scores than children with cancer, and significantly higher mean scores than healthy counterparts. This reflected that childhood cancer survivors had a better sleep quality than children with cancer, but a poorer sleep quality than healthy counterparts. We observed positive correlations between PSQI and CES-DC scores and between PSQI and FS-A/FS-C scores, but a negative correlation between PSQI and PedsQL scores. The results supported that the Chinese version of the PSQI showed convergent validity. Confirmatory factor analysis showed that the translated PSQI data best fit a three-factor model. The best cutoff score to detect insomnia was 5, with a sensitivity of 0.81 and specificity of 0.70. Conclusion The Chinese version of the PSQI is a reliable and valid instrument to assess subjective sleep quality among Hong Kong Chinese childhood cancer survivors. The validated PSQI could be used in clinical settings to provide early assessments for sleep disruption. Appropriate interventions can therefore be provided to minimize its associated long-term healthcare cost. Trial registration This study was registered in ClinicalTrials.gov with the reference number NCT03858218.

Abstract
BACKGROUND Sleep disturbances constitute a common complication in pediatric cancer patients and survivors and are frequently severe enough to warrant treatment. Suboptimal sleep has been associated with decreased emotional well-being and cognitive functioning and increased behavioral problems. Standardized guidelines for non-pharmacological sleep interventions for adults with cancer exist, but no standard of care intervention or standard guidelines are available to guide such intervention in pediatric cancer patients and survivors. Therefore, effective behavioral interventions for improving sleep quality need to be identified. The objective of the review is to evaluate the effect of non-pharmacological sleep interventions on sleep quality in pediatric cancer patients and survivors. METHODS The review will consider studies that include children and adolescents between 0 and 18 years diagnosed with cancer or who have a history of cancer who have non-respiratory sleep disturbance. We will include experimental and quasi-experimental studies evaluating non-pharmacological interventions such as psychological interventions, technical/device interventions, interventions targeting physical activity, and complementary and alternative medicine interventions (e.g., yoga, massage, music). Interventions involving medications, ingestible supplements, products purported to work through absorption, and medical devices will be excluded. Primary outcome will be sleep quality as measured by methods including retrospective ratings, daily sleep diary, and validated questionnaires. Secondary outcomes will include total sleep time, sleep onset latency, wake after sleep onset, daytime sleepiness, and daytime sleep duration (naps) as measured by retrospective ratings, daily sleep diary, validated questionnaires, and/or actigraphy. Databases will include MEDLINE (Ovid), EMBASE (Ovid), Cochrane Library, CINAHL (Ebsco), and PsycINFO (Ovid) and will be queried from database inception to present. Two reviewers will independently screen all citations, full-text articles, and extract data. The study methodological quality will be assessed using Joanna Briggs Institute (JBI) critical appraisal tools. Data will be extracted and findings pooled and synthesized using a meta-aggregation approach via the JBI System for the Unified Management, Assessment, and Review of Information (SUMARI). If feasible, we will conduct random effects meta-analysis. Additional analyses will be conducted to explore the potential sources of heterogeneity (e.g., methodological quality, study design, outcome measures). DISCUSSION This systematic review will synthesize and consolidate evidence on existing non-pharmacological interventions to improve sleep in pediatric cancer patients and survivors. Findings may help inform practitioners working with pediatric cancer patients and survivors experiencing sleep disturbances and is intended to identify gaps and opportunities to improve methodical quality of further non-pharmacological sleep intervention research in this population toward developing an eventual standard of care.

Abstract
OBJECTIVES Sleep problems are a common late effect in survivors of pediatric cancer. Growing literature suggests deficits in sleep functioning may be related to more impairing neurobehavioral outcomes. The purpose of the present study was to evaluate the prevalence of parent reported sleep concerns in survivors of pediatric cancer, as well as evaluate the relationship between sleep and neurobehavioral functioning utilizing both parent and teacher input. METHODS The study included parent-teacher dyads of 75 survivors of pediatric cancer between the ages of six and 17 who completed a clinical neuropsychological evaluation with embedded measures of neurobehavioral functioning and sleep, including excessive daytime sleepiness and snoring. Bivariate correlations and multiple linear regressions were conducted to evaluate the relationship between sleep and neurobehavioral functioning. RESULTS No significant difference in parent reported sleep concerns was found with regard to demographic, diagnostic, or treatment variables. Daytime sleepiness was significantly elevated for 28% of the sample; snoring was not identified as a significant concern. Daytime sleepiness was significantly associated with worse neurobehavioral outcomes as reported by parents and teachers, including inattention, hyperactivity/impulsivity, peer difficulties, anxiety, depression, somatic complaints, and aggressive behaviors. Daytime sleepiness was not significantly related to report of learning problems. CONCLUSIONS Results further support that daytime sleepiness, as reported by parents, impacts approximately one third of survivors of pediatric cancer and is associated with worse neurobehavioral outcomes across home and school environments. As a result, it is vital that sleep functioning is a target of assessment in annual survivorship care. Future longitudinal studies are needed to further delineate the directionality of the sleep-neurobehavioral relationship in survivors.

Abstract
OBJECTIVE Sleep disturbances have been identified by patients with cancer as common and distressing; however, conflicting evidence about the prevalence of these outcomes exists for survivors of childhood cancers. Additionally, little is known about how the experience of cancer might impact survivor siblings' sleep. The current study compared the sleep of survivors of acute lymphoblastic leukemia who were 2-7 years off therapy and their siblings to healthy control/sibling dyads. METHODS Participants (survivors, n = 45; survivor siblings, n = 27; controls, n = 45; control siblings, n = 41; 58% male) aged 8-18 (m = 11.64) completed a 7-day sleep diary and seven consecutive days of actigraphy. Parents (n = 90) completed the Children's Sleep Habits Questionnaire for each of their children. RESULTS No between-group differences were found on measures of sleep diaries or actigraphy. Parents reported that survivor siblings had significantly poorer sleep habits than survivors or controls. For survivors, greater time off treatment and younger age at diagnosis were associated with less total sleep time, more wake after sleep onset, and decreased sleep efficiency via actigraphy. CONCLUSION Sleep across all groups was consistent and below national guidelines. Although the survivor group did not have poorer sleep compared to their siblings or matched controls, within the survivor group, those who were diagnosed at an earlier age and those who were further off treatment had more disrupted sleep. Parent reports suggested that survivor siblings may be at risk for sleep problems.

Abstract
Cognitive impairment is frequent in pediatric cancer, and behavioral and psychological disturbances often also affect children who have survived cancer problems. Furthermore, pediatric tumors are also often associated with sleep disorders. The interrelationship between sleep disorders, neurodevelopmental disorders and pediatric cancer, however, is still largely unexplored. In this narrative review we approach this important aspect by first considering studies on pediatric cancer as a possible cause of neurodevelopmental disorders and then describing pediatric cancer occurring as a comorbid condition in children with neurodevelopmental disorders. Finally, we discuss the role of sleep disorders in children with cancer and neurodevelopmental disorders. Even if the specific literature approaching directly the topic of the role of sleep in the complex relationship between pediatric cancer and neurodevelopmental disorders was found to be scarce, the available evidence supports the idea that in-depth knowledge and correct management of sleep disorders can definitely improve the health and quality of life of children with cancer and of their families.
