Fatigue in children who have recently completed treatment for acute lymphoblastic leukemia: a longitudinal study.

BACKGROUND: This study examined fatigue in patients treated for childhood acute lymphoblastic leukemia (ALL) over a 2-year period (3- to 27-months post-treatment completion), from the perspective of children and parent caregivers, compared to a healthy comparison group. METHODS: Eighty-three patients (4-16 years at enrolment) and their parents, reported on the child's fatigue using the Pediatric Quality of Life Inventory- Multidimensional Fatigue Scale (PedsQL-MFS), at 3- 15- and 27-months post-treatment completion, and 53 healthy children and their parents reported on fatigue across the same timepoints. RESULTS: Parent proxy-reporting showed that parents of ALL patients reported more total fatigue than parents of the comparison group at all time points, with all subscales elevated (general, cognitive, and sleep/rest fatigue). In contrast, patient self-report of fatigue over this period differed from the comparison children for the general fatigue subscale only. Self-reported total fatigue was worse than the comparison group at the 27-month timepoint, with cognitive and sleep/rest fatigue symptoms contributing to this difference. Expected improvements in fatigue over time were not evident in either patient or parent report and no demographic risk factors were identified. Parents and children from both groups reported significantly more fatigue at all time points compared to commonly utilised normative population data. CONCLUSIONS: Patients treated for childhood ALL are impacted by fatigue symptoms in the post-treatment and early survivorship period. These findings highlight that patients in the 2-years following treatment require increased symptom surveillance and may benefit particularly from interventions that target cognitive and sleep/rest fatigue.

Behavioral and Emotional Functioning of Children and Adolescents at the End of Treatment for Acute Lymphoblastic Leukemia Compared to Healthy Peers.

This study describes the behavioral and emotional adjustment of 77 children and adolescents 3 months post-treatment for acute lymphoblastic leukemia (ALL), compared to 52 age and sex-matched healthy peers. Parents, teachers, and self-report ratings on the Behavioral Assessment System for Children, Second Edition (BASC-2) were utilized to measure psychological function. While overall mean scores were in the average range for both groups, parents and teachers rated patients higher on behavior symptoms, internalizing problems and adaptive skill difficulties. No significant differences between groups were observed on self-report, and inter-rater correlations were low to moderate. For the ALL group, maternal university completion was associated with elevations on parent report of behavioral problems, while no other factors predicted either parent or teacher report on other scales. Findings indicate that a subset of patients will require specialist psychosocial support to optimise their adjustment following treatment completion.

Parent perceptions of pediatric oncology care during the COVID-19 pandemic: An Australian study.

BACKGROUND: We examined parents' perceptions of their child's oncology care during a period of significant COVID-19 restrictions in Australia. METHODS: Parents of children, 0-18 years, receiving hospital-based cancer treatment, completed a survey examining their COVID-19 exposure and impact, information and knowledge, and perception of their child's medical care. Recruitment occurred between October and November 2020. RESULTS: Eighty-four parents (95% mothers) completed the survey. Sixty-seven percent of patients were diagnosed pre-COVID-19. The majority of parents (76%) reported negative impacts of COVID-19 on family life, including parenting and emotional well-being despite exposure to COVID-19 cases being very low (4%). Family functioning and parent birthplace were associated with COVID-19 impact and distress. Parents perceived the hospital as a safe place during the pandemic. Very few parents reported delaying presentation to the emergency department (12%). The majority identified no change (69%) or delay (71%) in their child's treatment delivery. Over 90% of parents were confident that COVID-19 did not impact medical decision-making. They felt confident in their COVID-19 knowledge and sought information from trusted sources. Parents reported a positive relationship with their child's care team (93%); however, access to some support services was reduced. CONCLUSION: Understanding patient and family experiences of pediatric oncology care across international contexts during the pandemic is important to inform present and future health care responses. In the Australian context of low infection rates and strict community restrictions, parents perceived their child's oncology care to be relatively unaffected. However, findings indicate that family well-being was impacted, which warrants further investigation.

Parental adjustment following their child's completion of acute lymphoblastic leukemia treatment.

BACKGROUND: Few studies haveexamined parent and family adaptation in the early period following the end of childhood cancer treatment. We examined parent adjustment at the end of their child's treatment for acute lymphoblastic leukemia (ALL). METHODS: Parents of childhood cancer survivors (CCS), who were 3 months post-ALL treatment, and parents of typically developing children completed measures of psychological and family functioning. Parents of CCS also completed distress and posttraumatic stress symptom (PTSS) questionnaires related to their child's cancer experience. RESULTS: One hundred twenty-nine parents were recruited: 77 parents of CCS and 52 comparison parents. Overall mean psychological symptoms of depression, anxiety and stress, and family functioning were within normal limits for both groups. Parents of CCS endorsed higher scores for stress, depression, and family problems; however, mean scores for emotional distress were low for both groups, in particular the comparison group. Parents of CCS endorsed low rates of PTSS. Fifty-one percent of parents of CCS scored above the distress thermometer (DT-P) clinical cutoff (>4), with items elevated across all six DT-P domains. However, most parents did not indicate a wish to speak to a health professional about their symptoms. CONCLUSION: Specialist psychosocial intervention may be indicated for only a subset of parents at the end of treatment. As per psychosocial standards of care, effective screening at this timepoint is warranted. Further examination of appropriate timing of psychosocial information and support services that are tailored to parents' circumstances is needed. eHealth approaches may be appropriate.

Health-related quality of life in paediatric patients up to five years post-treatment completion for acute lymphoblastic leukaemia: a systematic review.

PURPOSE: Despite survival rates greater than 90%, treatment for paediatric acute lymphoblastic leukaemia (ALL) remains challenging for families. The early post-treatment phase is an especially unique time of adjustment. The primary aim of this review was to identify and synthesise research on health-related quality of life (HRQoL) for patients up to five years post-treatment. The secondary aim was to identify if theorised risk/resistance model factors could explain any variance in reported HRQoL. METHODS: We conducted a systematic review using the PRISMA guidelines across five databases: Embase, Medline, Psychinfo, Pubmed, and Cochrane. Only studies examining HRQoL up to five years post-treatment were included. Studies were excluded if they covered periods greater than five years post-treatment or did not differentiate between patients with ALL and other cancers. After assessing the quality of each study sample size, patient characteristics, HRQoL outcomes and HRQoL correlates were extracted and summarised. RESULTS: A total of 14 studies representing 1254 paediatric patients, aged 2-18 years, were found. HRQoL findings were mixed, dependent on time since completion and comparison group. Patient HRQoL was mostly lower compared to normative data, whilst higher compared to healthy control groups, patients on treatment, and patients with other types of cancers. Lower HRQoL was also found to be associated with demographic (age and sex), family dysfunction, and treatment-related factors. CONCLUSIONS: Completing treatment signalled a significant improvement in HRQoL for patients compared to being on treatment. Overall, however, HRQoL was still significantly lower than the population during the early post-treatment period.

Family Functioning and Mood and Anxiety Symptoms in Adolescents Born Extremely Preterm.

OBJECTIVE: To (1) compare adolescent- and parent-perceived family functioning between extremely preterm/extremely low birth weight (<28 wk/<1000 g, EP/ELBW) and normal birth weight (>2499 g, NBW) adolescents and (2) determine whether adolescents' or parents' ratings of family functioning were related to concurrent depression and anxiety symptoms in the adolescent and whether these relationships varied by birth group. METHODS: One hundred ninety-three EP/ELBW and 151 NBW adolescents (aged 15-20 yr) and their parents rated aspects of family functioning on the Family Environment Scale. Adolescents rated current depression and anxiety symptoms on the Center for Epidemiologic Studies Depression Scale-Revised and Beck Anxiety Inventory. Family functioning was compared across the groups using linear regression, and logistic regression was used to assess relationships between family functioning domains and elevated depression and anxiety scores. RESULTS: Compared with NBW controls, EP/ELBW adolescents reported similar levels of family Cohesiveness and Expressiveness, but less Conflict, and more Organization and Control. Parent ratings of family functioning were similar between groups except for higher Control scores in EP/ELBW group parents. Poorer family functioning as rated by adolescents, but not parents, was associated with increased depression/anxiety symptoms. These findings were generally consistent across both the EP/ELBW and control groups. CONCLUSION: EP/ELBW adolescents report generally positive family functioning. While adolescents' perceptions of family functioning are associated with concurrent adolescent mental health, parental perceptions of family functioning may not be indicative of adolescents' mental health. Importantly, EP/ELBW adolescents do not appear to be more vulnerable to anxiety/depression in the context of poorly perceived family functioning than their NBW peers.

Motor functioning during and following treatment with chemotherapy for pediatric acute lymphoblastic leukemia.

This systematic review evaluated empirical studies examining motor skills in children during and following treatment for acute lymphoblastic leukemia. Most studies indicated that children on-treatment display poorer gross and fine motor abilities than healthy peers, but generally have intact visual-motor integration skills. Studies have reported gross motor difficulties in 5-54% of survivors. There is some limited evidence for long-term fine motor deficits. The evidence for visual-motor integration difficulties in the survivor population is less consistent. Larger studies with a longitudinal design are needed to further specify the onset and timing of motor difficulties and ascertain risk factors.

Gross and fine motor skills in children treated for acute lymphoblastic leukaemia.

OBJECTIVE: Chemotherapy treatment for acute lymphoblastic leukaemia (ALL) may disrupt motor development, with suggestions that gross and fine motor deficits are different depending on time since treatment. METHODS: Thirty-seven participants aged between 2.5 to 5 years at the time of diagnosis were assessed using the Movement Assessment Battery for Children, 2nd Edition (MABC-2) and the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition, Short Form (BOT-2 SF), and divided into groups (i.e., months-off-treatment): (1) 0-12, (2) 13-24, and (3) 25-60 for comparison. RESULTS: MABC-2 and BOT-2 SF mean total scores fell within the average range. Twenty-six percent of the sample performed in the impaired range on the MABC-2. Group 2 had significantly lower Manual Dexterity scores than the normative population and lower BOT-2 SF scores than Group 1. CONCLUSION: Most children treated for ALL display appropriate motor skills, yet around a quarter experience general motor difficulties. Time-off-treatment did not affect the prevalence of motor impairments on any measure.

School-age outcomes of extremely preterm or extremely low birth weight children.

OBJECTIVE: Research is required to monitor changes in the nature of neurobehavioral deficits in extremely preterm (EP) or extremely low birth weight (ELBW) survivors. This study examines cognitive, academic, and behavioral outcomes at age 8 years for a regional cohort of EP/ELBW children born in 1997. METHODS: The EP/ELBW cohort comprised all live births with a gestational age <28 weeks (EP) or birth weight <1000 g (ELBW) born in the state of Victoria, Australia, in 1997. Of 317 live births, 201 (63.4%) survived to 2 years of age.A term/normal birth weight (T/NBW) cohort was recruited comprising 199 infants with birthweights ≥2500 g or gestational age ≥37 weeks [corrected]. Measures of intellectual ability, educational achievement, and behavior were administered at age 8. RESULTS: Retention was 94% for the EP/ELBW group and 87% for the T/NBW group. The EP/ELBW group performed poorer than the T/NBW group on measures of IQ, educational achievement, and certain behavioral domains, even after adjustment for sociodemographic factors and exclusion of children with neurosensory impairment. The rate of any neurobehavioral impairment was elevated in the EP/ELBW group (71% vs 42%), and one-half of subjects had multiple impairments. The outcomes for those with <750 g birth weight or <26 weeks' gestational age were similar to those with a birth weight of 750 to 999 g or a gestational age of 26 to 27 weeks, respectively. CONCLUSIONS: Despite ongoing improvements in the management of EP/ELBW infants, the rate of neurobehavioral impairment at school-age remains too high relative to controls.

Feasibility of neurobehavioral screening following diagnosis of pediatric cancer.

BACKGROUND: Neurobehavioral deficits will affect up to 50% of pediatric cancer survivors treated with central nervous system (CNS)-directed therapies. Guidelines suggest assessment of neurobehavioral skills at diagnosis be extended from patients with brain tumors to include all patients requiring CNS-directed therapies. However, comprehensive neuropsychological assessment at diagnosis is difficult to implement and resource intensive. A screening assessment targeted at the neurobehavioral domains known to be impacted by cancer treatments may be more feasible. This study aimed to assess the feasibility of implementing baseline neurobehavioral screening following childhood cancer diagnosis. PROCEDURE: A consecutive sample of 59 recently diagnosed patients requiring CNS-directed therapies, and 49 healthy controls were assessed using a targeted neurobehavioral screen, which included measures of developmental, cognitive, academic, behavioral, and psychosocial functioning. Feasibility was assessed using a formal feasibility framework, with criteria of brevity, simplicity, relevance, acceptability, and value. Neurobehavioral assessment was compared to standard care to determine the quality of information acquired from the screen. RESULTS: Mean time from diagnosis to assessment was 5.17 weeks. Assessments were completed within 1 hour for 87% of patients. Participant and researcher evaluation indicated the screen was acceptable across a range of criteria, with no differences between clinical and control groups. Compared to standard medical record documentation, the screen provided significant additional information on developmental and neurobehavioral status of patients at diagnosis. CONCLUSION: A brief neurobehavioral screen in the early period following cancer diagnosis is feasible and provides valuable baseline data for children at risk of neurobehavioral late-effects of cancer treatments.

Attention problems in a representative sample of extremely preterm/extremely low birth weight children.

The aim of this study was to examine attention in a large, representative, contemporary cohort of children born extremely preterm (EP) and/or extremely low birth weight (ELBW). Participants included 189 of 201 surviving children born EP (<28 weeks' gestation) or ELBW (<1,000 g) in 1997 in the state of Victoria, Australia. A comparison group of 173 of 199 children born full term and normal birth weight (FT/NBW) were randomly selected matching for birth hospital, expected due date, gender, mother's country of birth, and health insurance status. Participants were assessed at 8 years of age on subtests from the Test of Everyday Attention for Children (TEA-Ch) and the Wechsler Intelligence Scale for Children-4th Edition (WISC-IV). Measures of selective attention, sustained attention, attention encoding, and executive attention (inhibition, shifting attention, and divided attention) were administered. To assess behavioral elements of inattention, the primary caregiver completed the Behavior Rating Inventory of Executive Function (BRIEF) and the Conners' ADHD/DSM-IV Scale (CADS-P). The EP/ELBW group performed more poorly across all cognitive and behavioral measures than the FT/NBW group, with the exception of inhibition. The EP/ELBW group also had significantly elevated rates of impairment in selective, sustained, shifting and divided attention, as well as attention deficit hyperactivity disorder (ADHD) symptoms. No significant gender or gradient effects (e.g., <26 weeks' gestation vs. ≥ 26 weeks' gestation) were identified. Neonatal medical factors were not strong predictors of attention, although necrotizing enterocolitis (NEC) and cystic periventricular leukomalacia (PVL) were independent predictors of selective attention. In conclusion, our comprehensive assessment of attention provides strong evidence that children born EP/ELBW are at increased risk for attentional impairments, and as such, this population should be monitored closely during early and middle childhood with a focus on attention functioning.

Underestimation of developmental delay by the new Bayley-III Scale.

OBJECTIVE: To assess the ability of the third edition of the Bayley Scales of Infant and Toddler Development (Bayley-III) to detect developmental delay in 2-year-old children who were extremely preterm and those carried to term. DESIGN: Prospective cohort study. SETTING: The state of Victoria, Australia. PARTICIPANTS: Subjects were consecutive surviving children who were born either at less than 28 weeks' gestational age (extremely preterm) or with less than 1000 g birth weight (extremely low-birth-weight; n = 221) in the state of Victoria, Australia, in 2005 and randomly selected controls who were both carried to term and of normal birth weight (n = 220). MAIN OUTCOME MEASURE: Children were assessed by psychologists blinded to knowledge of group at 2 years of age, corrected for prematurity with the new Bayley-III scale. RESULTS: Follow-up rates of both cohorts were high (>92%). Mean values for all composite and subtest scores for the extremely preterm/extremely low-birth-weight group were significantly below those of the control group (P < .001), with the magnitude of all group differences being in excess of two-thirds SD. Mean values for the extremely preterm/extremely low-birth-weight group approached the normative mean, but in contrast, the mean values for the control group were higher than expected, with composite scores being between 0.55 and 1.23 SD above the normative mean. Proportions of children with developmental delay were grossly underestimated using the reference values, but were within the expected range when computed relative to the mean (standard deviation) for the controls. CONCLUSION: The Bayley-III scale seriously underestimates developmental delay in 2-year-old Australian children.

Normative data from the CANTAB. I: development of executive function over the lifespan.

The study of executive function within a developmental framework has proven integral to the advancement of knowledge concerning the acquisition and decline of higher skill processes. Still in its early stages, there exists a discontinuity in the literature between the exploration of executive capacity in young children and the elderly. Research of age-related differences utilising a lifespan approach has been restricted by the lack of assessment tools for the measurement of executive skills that are applicable across all age levels. This paper addresses these issues using the computer-based Cambridge Neuropsychological Test Automated Battery (CANTAB) to identify periods of development in executive capacities using a normative sample of 194 participants ranging in age from 8 to 64 years. Findings of executive function in children as young as 8 years of age were extended, with functional gains found in the efficiency of working memory capacity, planning and problem-solving abilities, between the ages of 15 and 19 years and again at 20-29 years of age. Cognitive flexibility was assessed at adult-levels in even the youngest children. Declines in performance on all tasks were revealed for the 50-64 year old sample, providing support for the vulnerability of executive skills to normal aging.
