Abstract
This study intended to explore the neuropsychological ramifications in childhood acute lymphoblastic leukemia (ALL) survivors in Malaysia and to examine treatment-related sequelae. A case-control study was conducted over a 2-year period. Seventy-one survivors of childhood ALL who had completed treatment for a minimum of 1 year and were in remission, and 71 healthy volunteers were enlisted. To assess alertness (processing speed) and essential executive functioning skills such as working memory capacity, inhibition, cognitive flexibility, and sustained attention, seven measures from the Amsterdam Neuropsychological Tasks (ANT) program were chosen. Main outcome measures were speed, stability and accuracy of responses. Mean age at diagnosis was 4.50 years (SD ± 2.40) while mean age at study entry was 12.18 years (SD ± 3.14). Survivors of childhood ALL underperformed on 6 out of 7 ANT tasks, indicating poorer sustained attention, working memory capacity, executive visuomotor control, and cognitive flexibility. Duration of treatment, age at diagnosis, gender, and cumulative doses of chemotherapy were not found to correlate with any of the neuropsychological outcome measures. Childhood ALL survivors in our center demonstrated significantly poorer neuropsychological status compared to healthy controls.

Genetic Factors and Long-term Treatment-Related Neurocognitive Deficits, Anxiety, and Depression in Childhood Leukemia Survivors: An Exome-Wide Association Study. Cancer Epidemiol Biomarkers Prev 2024; 33:234-243. [PMID: 38051303 PMCID: PMC10903523 DOI: 10.1158/1055-9965.epi-23-0634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/23/2023] [Accepted: 11/30/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND An increased risk of neurocognitive deficits, anxiety, and depression has been reported in childhood cancer survivors. METHODS We analyzed associations of neurocognitive deficits, as well as anxiety and depression, with common and rare genetic variants derived from whole-exome sequencing data of acute lymphoblastic leukemia (ALL) survivors from the PETALE cohort. In addition, significant associations were assessed using stratified and multivariable analyses. Next, top-ranking common associations were analyzed in an independent SJLIFE replication cohort of ALL survivors. RESULTS Significant associations were identified in the entire discovery cohort (N = 229) between the AK8 gene and changes in neurocognitive function, whereas PTPRZ1, MUC16, TNRC6C-AS1 were associated with anxiety. Following stratification according to sex, the ZNF382 gene was linked to a neurocognitive deficit in males, whereas APOL2 and C6orf165 were associated with anxiety and EXO5 with depression. Following stratification according to prognostic risk groups, the modulatory effect of rare variants on depression was additionally found in the CYP2W1 and PCMTD1 genes. In the replication SJLIFE cohort (N = 688), the male-specific association in the ZNF382 gene was not significant; however, a P value<0.05 was observed when the entire SJLIFE cohort was analyzed. ZNF382 was significant in males in the combined cohorts as shown by meta-analyses as well as the depression-associated gene EXO5. CONCLUSIONS Further research is needed to confirm whether the current findings, along with other known risk factors, may be valuable in identifying patients at increased risk of these long-term complications. IMPACT Our results suggest that specific genes may be related to increased neuropsychological consequences.

Abstract
OBJECTIVE The primary aim of this study was to assess the feasibility of a developmentally tailored neurocognitive assessment in survivors of childhood acute leukemia with Down syndrome (DS-leukemia). A secondary aim was to compare outcomes in the DS-leukemia group to a historical comparison group of individuals with DS and no history of childhood cancer. METHODS Survivors of DS-leukemia (n = 43; 56% male, mean [SD] age at diagnosis = 4.3 [4.5] years; age at evaluation = 15 [7.9] years) completed a neurocognitive assessment battery that included direct measures of attention, executive function, and processing speed, and proxy ratings of attention problems and executive dysfunction. Direct assessment outcomes were compared to a historical comparison cohort of individuals with DS and no history of childhood cancer (DS-control; n = 117; 56% male, mean [SD] age at evaluation = 12.7 [3.4] years). RESULTS Rates of valid task completion ranged from 54% to 95%, suggesting feasibility for most direct assessment measures. Compared to the DS-control group, the DS-leukemia group had significantly lower completion rates on measures of executive function (p = 0.008) and processing speed (p = 0.018) compared to the DS-control group. There were no other significant group differences in completion rates. Compared to the DS-control group, the DS-leukemia group had significantly more accurate performance on two measures of executive function (p = 0.032; p = 0.005). Compared to the DS-control group, the DS-leukemia group had significantly more problems with executive function as identified on proxy ratings (6.5% vs. 32.6%, p = <0.001). CONCLUSION Children with Down syndrome (DS) are at increased risk for developing acute leukemia compared to the general population but are systematically excluded from neurocognitive outcome studies among leukemia survivors. This study demonstrated the feasibility of evaluating neurocognitive late effects in leukemia survivors with DS using novel measures appropriate for populations with intellectual developmental disorder.

Abstract
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.

Abstract
PURPOSE Little is known regarding long-term neurocognitive outcomes in osteosarcoma and Ewing sarcoma (EWS) survivors despite potential risk factors. We evaluated associations among treatment exposures, chronic health conditions, and patient-reported neurocognitive outcomes in adult survivors of childhood osteosarcoma and EWS. METHODS Five-year survivors of osteosarcoma (N = 604; median age 37.0 years) and EWS (N = 356; median age 35.0 years) diagnosed at < 21 years from 1970 to 1999, and 697 siblings completed the Childhood Cancer Survivor Study Neurocognitive Questionnaire and reported chronic health conditions, education, and employment. Prevalence of reported neurocognitive difficulties were compared between diagnostic groups and siblings. Modified Poisson regression identified factors associated with neurocognitive difficulties. RESULTS Osteosarcoma and EWS survivors, vs. siblings, reported higher prevalences of difficulties with task efficiency (15.4% [P = 0.03] and 14.0% [P = 0.04] vs. 9.6%, respectively) and emotional regulation (18.0% [P < 0.0001] and 15.2% [P = 0.03] vs. 11.3%, respectively), adjusted for age, sex, and ethnicity/race. Osteosarcoma survivors reported greater memory difficulties vs. siblings (23.5% vs. 16.4% [P = 0.01]). Comorbid impairment (i.e., ≥ 2 neurocognitive domains) was more prevalent in osteosarcoma (20.0% [P < 0.001]) and EWS survivors (16.3% [P = 0.02]) vs. siblings (10.9%). Neurological conditions were associated with worse task efficiency (RR = 2.17; 95% CI = 1.21-3.88) and emotional regulation (RR = 1.88; 95% CI = 1.01-3.52), and respiratory conditions were associated with worse organization (RR = 2.60; 95% CI = 1.05-6.39) for EWS. Hearing impairment was associated with emotional regulation difficulties for osteosarcoma (RR = 1.98; 95% CI = 1.22-3.20). Patient report of cognitive difficulties was associated with employment but not educational attainment. CONCLUSIONS Survivors of childhood osteosarcoma and EWS are at increased risk for reporting neurocognitive difficulties, which are associated with employment status and appear related to chronic health conditions that develop over time. IMPLICATIONS FOR CANCER SURVIVORS Early screening, prevention, and treatment of chronic health conditions may improve/prevent long-term neurocognitive outcomes.

Abstract
PURPOSE Evidence suggests an increased long-term risk of major psychiatric disorders (MPDs) in childhood and adolescent cancer survivors (CACSs). However, definitive conclusions regarding such associations and whether such associations vary for different types of cancers remain unclear. METHODS Using a nationwide data set from 2001 to 2011, we enrolled CACSs and likewise randomly selected individuals without cancer from the general population (1:10 ratio) who were matched to the CACSs with regard to demographic data. We investigated eight organ system-related cancers. The primary outcomes were the risks of seven MPD diagnoses: autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and post-traumatic stress disorder. RESULTS CACSs (n = 5,121; mean age = 9.08 years) showed increased risks of six MPD diagnoses than controls (n = 51,210), with results as follows (in descending order): ASD (hazard ratio [HR], 10.42; associated 95% CI, 4.58 to 23.69), ADHD (HR, 6.59; 95% CI, 4.91 to 8.86), BD (HR, 2.93; 95% CI, 1.26 to 6.80), MDD (HR, 1.88; 95% CI, 1.26 to 2.79), OCD (HR, 3.37; 95% CI, 1.33 to 8.52), and post-traumatic stress disorder (HR, 6.10; 95% CI, 1.46 to 25.54). CACSs also showed earlier ages at diagnoses of ADHD, schizophrenia, MDD, and OCD than controls. The risks of MPD diagnoses vary according to specific cancer types/categories. Brain cancer and lymphatic/hematopoietic tissue cancer were associated with the greatest number of MPD diagnoses (ie, each was associated with six diagnoses). In addition, ASD and ADHD were associated with most organ system-related cancers (ie, each was associated with five categories). CONCLUSION We found that CACSs were at higher risks of MPD diagnoses than controls. Follow-up care should include psychosocial interventions focusing on early signs of mental health problems and early interventions in this high-risk group.

Abstract
ABSTRACT Children with acute lymphoblastic leukemia (ALL) often experience treatment-related neurocognitive deficits and significant pain. Pain may exacerbate these cognitive impairments. This study examined neuropathic pain and neurocognitive outcomes in survivors of childhood ALL treated with contemporary therapy on a clinical trial (NCT00137111). There were 345 survivors (45% female, M = 6.9 years at diagnosis) who completed neurocognitive assessments including measures of sustained attention, learning and memory, and parent ratings of attention during at least one of 4 time points: on-therapy (Induction and Reinduction), end of therapy, and 2 years post-therapy. At-risk performance was defined as a score at least 1SD below the age-adjusted mean. Data on neuropathic pain (events, duration, and severity according NCI Common Toxicity Criteria) and pharmacologic pain management (opioids and gabapentin) were ascertained. Results showed that 135 survivors (39%) experienced neuropathic pain during treatment. Compared with those without pain, survivors with pain had greater memory impairments at end of therapy (California Verbal Learning Test [CVLT]-Total, 24% vs 12%, P = 0.046). Within the pain group, survivors who experienced a greater number of pain events (CVLT-Total = -0.88, P = 0.023) and those who were treated with opioids (versus gabapentin) had poorer learning and memory performance (CVLT-Total = -0.73, P = 0.011; Short Delay = -0.57, P = 0.024; Long Delay = -0.62, P = 0.012; and Learning Slope = -0.45, P = 0.042) across time points. These are considered medium-to-large effects (SD = 0.45-0.88). Neuropathic pain may be a risk factor for learning problems after therapy completion, and treatment for pain with opioids may also adversely affect neurocognitive performance. Therefore, patients who experience pain may require closer monitoring and additional intervention for neurocognitive impairment.

Abstract
The aim of the study was to determine the feasibility of the Persian version of the Canadian Occupational Performance Measure (COPM) to assess self-reported occupational performance in a group of children with cancer at least one-year post-cancer diagnosis and intervention and to describe the self-reported occupational performance problems of children with cancer. Forty-three children with cancer (mean age 11.59 years; SD 4.94) participated in a cross-sectional study, using a convenience sampling approach. Performance and satisfaction were assessed through a validated Persian version of the COPM and feasibility and ease of administration were also considered. This study showed that feasibility was found to be adequate and this measurement was perceived as easy to understand; completion took from 20 to 51 minutes. Children with cancer prioritized 115 occupations within six of the nine COPM subcategories. Among the prioritized occupations, the highest number was found in self-care 61.7%, followed by productivity (26%), and leisure (12.1%). The mean ratings of performance varied from 3.7 to 8.4. The lowest mean rating was in the subgroup play/school (3.7). For satisfaction, the mean ratings were from 2.6 to 5.2, with functional mobility as the highest and play/school the lowest. The results support the use of the COPM in clinical practice for children with cancer. Based on these findings, children with cancer perceive problems with occupations related to all aspects of daily life. This underlines the need to provide rehabilitation services, especially occupational therapy services for these children.

Abstract
Simple Summary In this study, we investigated standardized post-chemotherapy magnetic resonance (MR) scans for leukoencephalopathy and patient- and treatment-related risk factors in childhood leukemia patients. As prevalence numbers are limited, our study provides the required estimations for this population. Furthermore, we demonstrate that younger patients might be more at-risk for development of leukoencephalopathy (LE), and that a higher intravenous methotrexate (IV-MTX) dose has a cumulative toxic effect, while the number of intrathecal administrations was not significantly associated with the extent of LE. This can suggest we should modify chemotherapeutic treatment regimens by decreasing the number of IV-MTX applications, with special attention for younger patients. Abstract Methotrexate (MTX) is associated with leukoencephalopathy (LE) in children treated for lymphoblastic leukemia/lymphoma (ALL/LBL). However, large-scale studies with systematic MR acquisition and quantitative volumetric lesion information remain limited. Hence, the prevalence of lesion burdens and the potential risk factors of LE in this population are still inconclusive. FLAIR-MRI scans were acquired at the end of treatment in children who were treated for ALL/LBL, which were quantitatively analyzed for LE. Voxels were assigned to the lesion segmentation if indicated by two raters. Logistic and linear regression models were used to test whether lesion presence and size were predicted by risk factors such as age at diagnosis, gender, intrathecal (IT-) or intravenous (IV-)MTX dose, CNS invasion, and acute neurological events. Patients with a pre-existing neurological condition or low-quality MR scan were excluded from the analyses. Of the 129 patients, ten (8%) suffered from CNS invasion. Chemotherapy-associated neurological events were observed in 13 patients (10%) during therapy, and 68 patients (53%) showed LE post-treatment. LE was more frequent in cases of lower age and higher cumulative IV-MTX doses, while the extent of LE and neurological symptoms were associated only with IV-MTX doses. Neurological events were not significantly associated with LE, even though symptomatic patients demonstrated a higher ratio of LE (n = 9/13) than asymptomatic patients (n = 59/116). This study suggests leukoencephalopathy frequently occurs in both symptomatic and asymptomatic leukemia patients. Younger children and patients treated with higher cumulative IV-MTX doses might need more regular screening for early detection and follow-up of associated sequelae.

Abstract
Children with acute leukemia (ALL) often suffer from several disease and treatment related side-effects during treatment. The aim of the present study was to determine the gross and fine motor functioning and basic cognitive performance of children (n = 25) with ALL who were undergoing induction or consolidation chemotherapy and to compare these characteristics to a normative group (n = 21) of age-matched typically developing children. We assessed the children's motor functions with the Bruininks-Oseretsky Test of Motor Proficiency Second Edition-Short Form and the Nine-hole Peg Test, and we used the Modified Mini-Mental State Exam (MMSE) to evaluate their cognitive performance. Compared to the normative group, children with ALL had lower scores on total motor proficiency and sub-tests scores of motor functions (p < .05), and on the Nine-hole Peg Test performance (p < .05); but their cognitive performance on the MMSE was not significantly different. Children with ALL would likely benefit from structured exercise and rehabilitative interventions during chemotherapy to prevent and/or ameliorate ALL-related motor dysfunction. We also suggest that their cognitive functioning should be further investigated with more extensive well-validated neurocognitive tests for children (e.g., the Wechsler intelligence scales).

Abstract
The current 5-year survival rate for cancer in infants is greater than 75% in developed countries. However, survivors of neonatal malignancies have an increased risk of late effects from their tumor or its treatment, which may lead to long-term morbidity and/or early mortality. This article reviews surgical approaches and chemotherapeutic agents commonly used in neonatal malignancies and their associated late effects. It also reviews the increased risk for late effects associated with radiation at a young age and hematopoietic stem cell transplantation at a young age.. It highlights the importance of survivor-specific multidisciplinary care in the long-term management of neonatal cancer survivors.

Psychological, educational, and social late effects in adolescent survivors of Wilms tumor: A report from the Childhood Cancer Survivor Study. Psychooncology 2020; 30:349-360. [PMID: 33113206 DOI: 10.1002/pon.5584] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 08/31/2020] [Accepted: 10/13/2020] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To delineate the impact of treatment exposures and chronic health conditions on psychological, educational, and social outcomes in adolescent survivors of Wilms tumor. METHODS Parent reports from the Childhood Cancer Survivor Study were analyzed for 666 adolescent survivors of Wilms tumor and 698 adolescent siblings. Adjusting for race and household income, survivors were compared to siblings on the Behavior Problems Index and educational outcomes. Multivariable modified Poisson regression estimated relative risks (RR) for therapeutic exposures and chronic health conditions (CTCAE 4.03 graded) among survivors, adjusting for sex, race, income, and age at diagnosis. RESULTS Compared to siblings, adolescent survivors of Wilms tumor were more likely to take psychoactive medication (9.4% vs. 5.1%, p < 0.001) and utilize special education services (25.5% vs. 12.6%, p < 0.001) but did not differ significantly in emotional and behavioral problems. Survivors were less likely to be friendless (7.2% vs. 10.1%, p = 0.04) but were more likely to have difficulty getting along with friends (14.5% vs. 7.8%, p < 0.001). Among survivors, use of special education services was associated with abdomen plus chest radiation (RR = 1.98, CI:1.18-3.34). Those with grade 2-4 cardiovascular conditions had higher risk for anxiety/depression (RR = 1.95, CI:1.19-3.19), headstrong behaviors (RR = 1.91, CI:1.26-2.89), and inattention (RR = 1.56, CI:1.02-2.40). CONCLUSIONS Adolescent survivors of Wilms tumor were similar to siblings with respect to mental health concerns overall but were more likely to require special education. Monitoring of psychosocial and academic problems through adolescence is warranted, especially among those treated with radiation to the abdomen plus chest or with cardiac conditions.

Abstract
OBJECTIVES Children diagnosed with acute lymphoblastic leukemia (ALL) in their early childhood are more susceptible to neuromuscular and musculoskeletal impairments. This cross-sectional study was designed to address different types of fine motor impairments in Egyptian children diagnosed with ALL. METHODS Fifty-four children treated for ALL in maintenance phase aged from four to seven years were compared with an age- and sex-matched control group. Fine motor performance was assessed using the total fine motor form of the Bruininks-Oseretsky Test of Motor Proficiency-second edition (BOT-2). Sex- and age-specific norms of BOT-2 were used to calculate scale and standard scores in both groups. RESULTS Children with ALL had significantly impaired fine motor skills in all subtests and composites of BOT-2 compared with the typically developing group (P < 0.00001). Cumulative doses of vincristine, methotrexate, and dexamethasone revealed no significant correlation with any BOT-2 measure. Males performed significantly better than females in all BOT-2 scores except for the fine motor integration subtest and the total fine motor control composite as no significant differences were observed. The protocol risk stratum, duration of maintenance treatment, and the age at assessment did not significantly affect the BOT-2 measures. CONCLUSION About 67% of children with ALL on maintenance treatment experienced fine motor difficulties. Periodic evaluation along the course of chemotherapy could identify specific impaired fine motor domains providing the base for a successful rehabilitation program.

Abstract
This study sought to characterize auditory attention functioning among pediatric Acute Lymphoblastic Leukemia (ALL) survivors treated on a chemotherapy-only protocol, given previous literature suggesting late impact on sustained visual attention. We hypothesized similar deficits would be observed in auditory attention relative to previous literature indicating weakness with aspect of visual attention in this population. Survivors (n = 107, 53 females, M = 12.80 years) completed the Conners Continuous Auditory Test of Attention (CATA). Parents completed the Behavior Assessment System for Children, Second Edition and reported educational performance and services via structured questionnaire. Results indicated several CATA indices associated with sustained auditory attention were significantly worse than normative data, though group means were average. Reflecting individual variability in performance, 50% of the sample performed worse than one standard deviation from the mean on at least one CATA variable. Parent report of attention did not differ from normative means for the sample. Parent-report data indicated that 60% of the sample utilized academic support services, with a large proportion of survivors having utilized special education services. Poorer performance with sustained auditory attention was associated with poor academic outcomes. Greater methotrexate exposure and younger age at diagnosis were risk factors for inattentiveness. No gender differences were identified on direct assessment of auditory attention or parent report of attention, though male gender was associated with poorer educational performance. Findings suggest that auditory attention is an at-risk cognitive domain following treatment for pediatric ALL, and that an association exists between auditory attention and school performance in this population.

Cognitive Improvement After Kidney Transplantation Is Associated With Structural and Functional Changes on MRI. Transplant Direct 2020; 6:e531.

Abstract
Supplemental Digital Content is available in the text. Background. Several studies have reported improved cognitive outcomes after kidney transplantation, but most studies either did not include controls or lacked extensive neuroimaging. In addition, there is uncertainty whether kidney donation is a safe procedure in terms of cognitive outcomes. Methods. We prospectively studied neurocognitive function in kidney transplant recipients. The primary outcome was change in neurocognitive function after 1 year compared with baseline, which was evaluated using the Amsterdam Neuropsychological Task battery and verbal fluency tests. Secondary outcomes included changes in depression and anxiety (measured by the Hospital Anxiety and Depression scale) and changes in fatigue (measured by the Checklist for Individual Strength). We included kidney donors to control for learning effects, socioeconomic status, and surgery. In addition, kidney transplant recipients were evaluated with MRI scans at baseline and at year 1. The MRI protocol included conventional MRI, automated volumetric measurement, diffusion tensor imaging, magnetic resonance spectroscopy, arterial spin labeling, and a resting state functional MRI. Results. Twenty-seven recipients and 24 donors were included. For both recipients and donors, neuropsychologic testing scores improved 1 year after transplantation (donation). Recipient improvement significantly exceeded donor improvement on tasks measuring attention and working memory. These improvements were associated with increases in white matter volume and N-acetylaspartate/creatine (a marker for neuronal integrity). Conclusions. Attention and working memory improve significantly 1 year after kidney transplantation. Learning effects do not account for these improvements because recipient improvement in these areas exceeds donor improvement and correlates with an improvement in white matter integrity after transplantation. Kidney donation appears to be a safe procedure in terms of cognitive outcomes.

Abstract
BACKGROUND The impact of contemporary chemotherapy treatment for childhood acute lymphoblastic leukemia on central nervous system activity is not fully appreciated. METHODS Neurocognitive testing and functional magnetic resonance imaging (fMRI) were obtained in 165 survivors five or more years postdiagnosis (average age = 14.4 years, 7.7 years from diagnosis, 51.5% males). Chemotherapy exposure was measured as serum concentration of methotrexate following high-dose intravenous injection. Neurocognitive testing included measures of attention and executive function. fMRI was obtained during completion of two tasks, the continuous performance task (CPT) and the attention network task (ANT). Image analysis was performed using Statistical Parametric Mapping software, with contrasts targeting sustained attention, alerting, orienting, and conflict. All statistical tests were two-sided. RESULTS Compared with population norms, survivors demonstrated impairment on number-letter switching (P < .001, a measure of cognitive flexibility), which was associated with treatment intensity (P = .048). Task performance during fMRI was associated with neurocognitive dysfunction across multiple tasks. Regional brain activation was lower in survivors diagnosed at younger ages for the CPT (bilateral parietal and temporal lobes) and the ANT (left parietal and right hippocampus). With higher serum methotrexate exposure, CPT activation decreased in the right temporal and bilateral frontal and parietal lobes, but ANT alerting activation increased in the ventral frontal, insula, caudate, and anterior cingulate. CONCLUSIONS Brain activation during attention and executive function tasks was associated with serum methotrexate exposure and age at diagnosis. These findings provide evidence for compromised and compensatory changes in regional brain function that may help clarify the neural substrates of cognitive deficits in acute lymphoblastic leukemia survivors.

Abstract
BACKGROUND The 5-year survival for pediatric acute lymphoblastic leukemia (ALL) is greater than 90%. One late effect of pediatric ALL associated with numerous long-term difficulties is neurocognitive deficits. The experience at our institution, as well as conversations with oncologists at other institutions, suggests an increase in the use of sedation during lumbar punctures (LPs) for treatment of pediatric ALL. Among the most common Children's Oncology Group (COG) ALL protocols, approximately 30 LPs are performed over 2-3 years. Studies in animals reveal that sedation drugs may harm the developing brain. Gaps in knowledge exist regarding their use in children, particularly repeated exposures. The purpose of this study is to summarize sedation practices for LPs related to the treatment of ALL at COG institutions. METHODS Responsible Individuals (RIs) of the Cancer Control Committee of COG were invited to complete an internet-based survey about sedation practices at their institutions. RESULTS Surveys were sent to 103 RIs with a 62% response rate (N = 64). A combined 2018 new patients with ALL were seen each year (mean = 31.5, range = 3-110) at the participating institutions. The majority (96%) of children with ALL received sedation for LPs. While there was considerable variability across institutions in the type of sedation given, the most common was propofol alone (n = 36, 56%). CONCLUSIONS A substantial number of children with ALL receive sedation for LPs; however, there is variation in the medication used. Better understanding of sedation practices in children with ALL may inform future research to investigate which methods are the safest, with an emphasis on long-term neurocognitive late effects.

Abstract
Acute lymphoblastic leukaemia (ALL) is the most common malignancy in children. Although the survival rate has increased dramatically over the last decades, patients struggle with the adverse side effects of treatment. Treatment for ALL includes chemotherapy and irradiation - both of which are linked to cognitive impairments and alterations in central nervous system (CNS) structure and function detected by neuroimaging and in neurocognitive studies. The present article is a meta-analysis of the existing evidence for the mechanisms underlying changes in the CNS and neurocognitive function in ALL survivors after treatment. We found that compared with controls, ALL survivors develop: (i) cognitive sequelae in intelligence, academics, attention, memory, processing speed and executive function domains; (ii) decreased grey and white matter volume in cortical and several subcortical brain regions, with functional changes particularly in frontal regions and the hippocampus; (iii) neurocognitive impairments related to CNS changes; and (iv) reduction, but not resolution, of late neurocognitive sequelae in patients in whom prophylactic irradiation was replaced by systemic/intrathecal chemotherapy. Continued work with advanced functional magnetic resonance imaging techniques will hopefully allow the detection of early CNS changes as biomarkers to help guide early diagnosis and intervention for neurocognitive defects in patients with childhood ALL.

Abstract
To investigate the cognitive and psychological outcomes of pediatric allogeneic HSCT survivors in China.A total of 135 3 to 18 years old children and adolescents who underwent allo-HSCT and survived at least 3 months post-HSCT were recruited and completed the assessments. Cognitive and psychological functions were assessed via age-appropriate standardized measures. Clinical information was extracted from the medical records.Forty one 3 to 6 years old children completed Psychological Questionnaires for 3 to 6 years Children. The scores of 21(51.2%) children in cognitive development dimension, 18(43.9%) in motor development dimension, 16(39.0%) in language development and social development dimension, 15(36.6%) in emotion and will dimension and 14(34.1%) in living habits dimension were less than the standard. Fifty six 8 to 16 years old children and adolescents completed the Depression Self-rating Scale for Children and 9 (16.1%) of these met the criteria of depression. Sixty nine 7 to 16 years old children and adolescents completed the screening for Child Anxiety Related Disorders and 7 (10.1%) of these met the criteria of anxiety, especially social phobia and school phobia. Eighty nine 6 to 18 years old children and adolescents completed the Symptom Checklist-90 and 43.8% to 77.5% of these experienced mild symptoms like obsession-compulsion (77.5%), hostility (64%), and interpersonal sensitivity (60.7%). Children treated with total body irradiation (TBI) showed more cognitive impairments like motor deficits than those without TBI. Also older children and adolescents had more symptoms like psychoticism.These findings demonstrated cognitive and psychological late effects of pediatric allo-HSCT survivors in a single center in China and highlighted that the survivors conditioned with TBI had more cognitive impairments and older children and adolescents had more symptoms. Early intervention in these children and adolescents might minimize the cognitive losses and psychological effects.

The Developmental Pathways of Preschool Children with Acute Lymphoblastic Leukemia: Communicative and Social Sequelae One Year after Treatment. CHILDREN-BASEL 2019; 6:children6080092.

Abstract
Early childhood is considered to be a period of rapid development, with the acquisition of abilities predicting future positive school competences. Motor, cognitive, and social difficulties related to cancer therapies heavily impact the development of children with cancer. This study focused on two main aims: To assess the developmental pathways of preschool children with acute lymphoblastic leukemia one year post-treatment and to compare these abilities both with those of a control group of healthy peers and with Italian norms. Forty-four children and their families, recruited through the Hematology-Oncologic Clinic of the Department of Child and Woman Health (University of Padua), agreed to participate in this study. The children’s mean age was 4.52 years (SD = 0.94, range = 2.5–6 years), equally distributed by gender, all diagnosed with acute lymphoblastic leukemia. Matched healthy peers were recruited through pediatricians’ ambulatories. Each family was interviewed adopting the Vineland adaptive behavior scales. Paired sample Wilcoxon tests revealed that children were reported to have significantly more developmental difficulties than their healthy peers. When compared with Italian norms, they scored particularly low in verbal competence, social, and coping skills. No significant association was found between treatment variables and developmental abilities. These findings suggest that the creation of specialized interventions, both for parents and children, may fill the possible delays in children’s development probably due to stress, lack of adequate stimulation, or difficult adaptation.

The relationship of child executive functions to parenting capacities in childhood acute lymphoblastic leukemia survivors. Pediatr Blood Cancer 2019; 66:e27761. [PMID: 31033172 PMCID: PMC6657494 DOI: 10.1002/pbc.27761] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 04/03/2019] [Accepted: 04/04/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE The current study examined associations between child executive functions and parenting capacities in long-term survivors of childhood acute lymphoblastic leukemia (ALL). METHODS Participants included 188 parent-child dyads; children were at least 8 years of age, 5 years postdiagnosis of ALL, and previously treated with chemotherapy only. Parents completed the Parental Protection Scale (PPS), Child Vulnerability Scale (CVS), and Decision-Making Questionnaire (DMQ). Children completed measures of executive functioning and general cognitive abilities. Multivariate multiple regression examined associations between child executive functioning and parenting, while controlling for child age, treatment risk, maternal education, and child intelligence quotient. An exploratory aim identified latent profiles of parenting capacities. RESULTS Higher child cognitive flexibility (β = -0.16, P = .02) and planning abilities (β = -0.16, P = .049) were related to less parental overprotection. No other neurocognitive measures were related to child autonomy in decision making or perceived child vulnerability. For the exploratory aim, we found (a) a large class defined by normative parenting (94.3%) and (b) a small class characterized by higher levels of child vulnerability and overprotection. Class membership was unrelated to executive functioning, but higher maternal education was related to higher odds of class 2 membership (OR = 0.58, P = .04). CONCLUSIONS Results suggest that parents respond to child executive function difficulties with greater overprotection, which may be adaptive but not conducive to the development of independence. Although most parents report normative levels of child vulnerability and overprotection, a small subset demonstrate parenting practices that may place some survivors at risk for adverse outcomes.

Abstract
Introduction: There is increasing concern for adverse cognitive late effects among survivors of pediatric acute lymphoblastic leukemia (ALL) given the widespread impact they have on academic achievement, particularly working memory and attention. We assessed performance among survivors and their healthy peers on a dual task paradigm measuring visual working memory (VWM) and visual attention independently and the dynamic relationship between the two. Assessing specific subsets within cognitive domains allows for understanding the distinct nature of cognitive impairments. Method: Participants were 34 survivors of ALL who have been off-treatment and disease free for 7.5 years; and 20 healthy controls, all between the ages of 10 and 18 years. We utilized behavioral single- and dual-task paradigms. In the dual tasks, participants maintained several items in VWM while performing a visual attention task (Eriksen Flanker Task) that required processing of a target stimulus while inhibiting the processing of distractor stimuli. The single tasks involved performing only the VWM task or only the visual attention task. Results: Results revealed survivors of ALL performed significantly worse than their healthy peers on the single visual attention task but not the single VWM task. Of particular interest, group differences were obtained on the dual VWM and visual attention tasks, such that the VWM and attention tasks reciprocally interfered with each other only among survivors and not their healthy peers. Conclusions: Our results highlight a core deficit in visual attention that is exacerbated by VWM demands among survivors of ALL. The implementation of tasks from cognitive neuroscience paradigms may be sensitive to cognitive impairments experienced by cancer survivors. Assessment and intervention practices among survivors of pediatric ALL are discussed.

Abstract
Background: Approximately 50% of survivors of childhood acute lymphoblastic leukemia (ALL) demonstrate cognitive impairments. However, the trajectory of change and contributing neuropathology is unclear, limiting our ability to tailor intervention content and timing. This study aimed to explore information processing abilities and brain morphology early post-treatment for pediatric ALL. Procedure: Twenty-one children at the end of ALL treatment and 18 controls underwent neuropsychological assessment. A subset also completed structural magnetic resonance imaging. Results: A principal component analysis generated two cognitive factors: information processing capacity and information processing speed. Compared to control group, the ALL group displayed deficits in capacity, but not speed. No group differences were identified in morphology. No relationship was identified between capacity or speed and morphology. Conclusion: Early cognitive intervention should target information processing abilities using a system-wide approach. Future studies should employ alternative imaging techniques sensitive to white-matter microstructure when exploring pathology underlying information processing deficits.

Abstract
PURPOSE To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT). METHODS One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.1] years) and 354 community controls (55.6% female; 35 [10.2] years) completed comprehensive neuropsychological testing and physical examination, including echocardiography/electrocardiography, pulmonary function tests, and endocrine evaluation. Self-report of emotional distress, HRQOL, and social attainment were collected. Impairment was defined in relation to both controls and normative data. Generalized linear models were developed to examine impact of treatment and chronic health conditions on outcomes. RESULTS WT survivors performed poorer than norms and controls in 6 of 16 cognitive variables and 1 of 8 HRQOL variables, with scores ranging from - 0.64 (mathematics) to - 0.21 (verbal fluency) standard deviations below expectations. Compared to controls, WT survivors were less likely to graduate college (odds ratio 2.23, 95% confidence interval 1.46-3.41) and had more moderate to severe neurologic conditions (18.4% vs 8.2%, p < 0.001), which were associated with poor memory (β = - 0.90, p < 0.001), attention (β = - 1.02, p < 0.001), and HRQOL general health (β = - 0.80, p = 0.0015). Treatment variables and cardiopulmonary morbidity (higher in survivors) were not associated with outcomes. CONCLUSIONS Survivors of WT demonstrate impairment in neurocognitive function and have lower social attainment during adulthood, with poorer neurocognitive function associated with neurologic morbidity. IMPLICATIONS FOR CANCER SURVIVORS Survivors of WT should be offered neurocognitive evaluations and rehabilitation. Neurologic conditions should be routinely assessed, and appropriate support offered to reduce risk for functional limitations.

Abstract
BACKGROUND A substantial number of survivors of childhood acute lymphoblastic leukemia suffer from treatment-related late adverse effects including neurocognitive impairment. While multiple studies have described neurocognitive outcomes in childhood acute lymphoblastic leukemia (ALL) survivors, relatively few have investigated their association with individual genetic constitution. METHODS To further address this issue, genetic variants located in 99 genes relevant to the effects of anticancer drugs and in 360 genes implicated in nervous system function and predicted to affect protein function, were pooled from whole exome sequencing data of childhood ALL survivors (PETALE cohort) and analyzed for an association with neurocognitive complications, as well as with anxiety and depression. Variants that sustained correction for multiple testing were genotyped in entire cohort (n = 236) and analyzed with same outcomes. RESULTS Common variants in MTR, PPARA, ABCC3, CALML5, CACNB2 and PCDHB10 genes were associated with deficits in neurocognitive tests performance, whereas a variant in SLCO1B1 and EPHA5 genes was associated with anxiety and depression. Majority of associations were modulated by intensity of treatment. Associated variants were further analyzed in an independent SJLIFE cohort of 545 ALL survivors. Two variants, rs1805087 in methionine synthase, MTR and rs58225473 in voltage-dependent calcium channel protein encoding gene, CACNB2 are of particular interest, since associations of borderline significance were found in replication cohort and remain significant in combined discovery and replication groups (OR = 1.5, 95% CI, 1-2.3; p = 0.04 and; OR = 3.7, 95% CI, 1.25-11; p = 0.01, respectively). Variant rs4149056 in SLCO1B1 gene also deserves further attention since previously shown to affect methotrexate clearance and short-term toxicity in ALL patients. CONCLUSIONS Current findings can help understanding of the influence of genetic component on long-term neurocognitive impairment. Further studies are needed to confirm whether identified variants may be useful in identifying survivors at increased risk of these complications.

Abstract
Aim: To examine the neurocognitive outcomes in children and adolescents with acute lymphoblastic leukemia (ALL) in remission who were treated with systemic chemotherapy only (CTO). Methods: Neurocognitive performances in 36 children and adolescents, aged 8.4-15.3 years, in long-term remission from ALL 4.3-12.4 years post diagnosis, without relapse, and with no pre-diagnosis history of neurodevelopmental disorder were compared with 36 healthy controls matched for gender, age, and parents' socio-economic status. The former patients and the healthy controls completed an extensive battery of standardized neuropsychological tests. Results: Survivors who were treated by CTO obtained significantly lower scores than did healthy controls on the domains of Copy and drawing (p = 0.001; Cohen's d 0.85; after controlling for Type 1 errors q = 0.006), Arithmetic (p = 0.001; Cohen's d 0.80; after controlling for Type 1 errors, q = 0.006), and Tactile sensory functions (p = 0.008; Cohen's d 0.65; after controlling for Type 1 errors, q = 0.03). Fifty percent of the ALL group were more than 1 SD below the control groups mean on Copy and drawing. There was an interaction between age and group (ALL vs. Control, p = 0.042) on Copy and drawing, indicating that the youngest ALL patients exhibited the worst performance. The oldest ALL patients performed equal to or better than the controls. A tendency in the same direction was seen for Arithmetic and Tactile sensory functions. The ALL survivors exhibited a steeper rising learning slope on repeated tests, with lower scores on a tactile problem-solving task, tactile sensory tests, verbal memory, and visual attention, but they performed as well as the controls when stimuli were repeated. Conclusion: The results indicate that neurocognitive long-term sequelae in ALL survivors are limited to specific domains - particularly complex drawing, arithmetic, and tactile processing, and novelty processing. Cognitive deficits are shown among the youngest ALL patients. Intervention programs and school programs should account for difficulties with processing new information and taking advantage of repetitions as a strength, which may prevent survivors from falling behind their peers.

Nutrients 2019; 11:nu11040936. [PMID: 31027240 PMCID: PMC6521088 DOI: 10.3390/nu11040936] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/18/2019] [Accepted: 04/22/2019] [Indexed: 01/25/2023] Open
Abstract
Methotrexate (MTX), a folic acid antagonist, is widely used in cancer treatment. However, treatment with MTX reduces hippocampal neurogenesis, leading to memory deficits. Hesperidin (Hsd) is a flavonoid glycoside that promotes anti-inflammation, acts as an antioxidant, and has neuroprotective properties. Consumption of Hsd enhances learning and memory. In the present study, we investigated the protective effects of Hsd against MTX-induced impairments of memory and neurogenesis; male Sprague Dawley rats were administered with a single dose of MTX (75 mg/kg) by intravenous (i.v.) injection on days 8 and 15 or Hsd (100 mg/kg) by oral gavage for 21 days. Memory was tested using novel object location (NOL) and novel object recognition (NOR) tasks. Immunofluorescence staining of Ki-67, bromodeoxyuridine (BrdU), and doublecortin (DCX) was performed to assess cell proliferation, survival, and immature neurons. The data showed that Hsd and MTX did not disable locomotor ability. The MTX animals exhibited memory deficits in both memory tests. There were significant decreases in the numbers of cell proliferation, survival, and immature neurons in the MTX animals. However, co-administration with MTX and Hsd alleviated memory loss and neurogenesis decline. These results revealed that Hsd could protect against MTX side effects in the animals in this study.

Abstract
Objective Attentional and academic difficulties, particularly in math, are common in survivors of childhood acute lymphoblastic leukemia (ALL). Of cognitive deficits experienced by survivors of childhood ALL, attention deficits may be particularly responsive to intervention. However, it is unknown whether deficits in particular aspects of attention are associated with deficits in math skills. The current study investigated relationships between math calculation skills, performance on an objective measure of sustained attention, and parent- and teacher-reported attention difficulties. Method Twenty-four survivors of childhood ALL (Mage = 13.5 years, SD = 2.8 years) completed a computerized measure of sustained attention and response control and a written measure of math calculation skills in the context of a comprehensive clinical neuropsychological evaluation. Parent and teacher ratings of inattention and impulsivity were obtained. Results Visual response control and visual attention accounted for 26.4% of the variance observed among math performance scores after controlling for IQ (p < .05). Teacher-rated, but not parent-rated, inattention was significantly negatively correlated with math calculation scores. Conclusions Consistency of responses to visual stimuli on a computerized measure of attention is a unique predictor of variance in math performance among survivors of childhood ALL. Objective testing of visual response control, rather than parent-rated attentional problems, may have clinical utility in identifying ALL survivors at risk for math difficulties.

DIVERGT screening procedure predicts general cognitive functioning in adult long-term survivors of pediatric acute lymphoblastic leukemia: A PETALE study. Pediatr Blood Cancer 2018; 65:e27259.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Because of major improvements in treatment protocols, the survival rate now exceeds 80%. However, ALL treatments can cause long-term neurocognitive sequelae, which negatively impact academic achievement and quality of life. Therefore, cognitive sequelae need to be carefully evaluated. The DIVERGT is a battery of tests proposed as a screening tool, sensitive to executive function impairments in children and adolescent cancer survivors. Our study aimed at verifying the predictive value of the DIVERGT on general cognitive functioning in adult long-term survivors of ALL. METHODS ALL survivors completed the DIVERGT 13.4 years, on average, after remission (N = 247). In addition, 49 of these survivors (equally selected amongst those with low, average, and high DIVERGT scores) as well as 29 controls completed a more comprehensive neuropsychological evaluation within a 3-year period from DIVERGT administration. Multivariate regression analysis was used to assess the predictive value of the DIVERGT on general intelligence, mathematics, verbal memory, and working memory. As a follow-up analysis, three performance groups were created based on the DIVERGT results. Multivariate analysis of variance (MANOVA) assessed neuropsychological differences between groups. RESULTS The DIVERGT accurately predicted General Ability Index (GAI) (P < 0.0001), mathematics (P < 0.0001) and verbal memory (P = 0.045). Moreover, the low-performance group consistently had poorer performance than the high-performance and control groups on the neuropsychological tests. CONCLUSION The DIVERGT is a useful, time-effective screening battery for broader neurocognitive impairments identification in long-term adult ALL survivors. It could be implemented as routine examination in cancer follow-up clinics.

Long-term psychological and educational outcomes for survivors of neuroblastoma: A report from the Childhood Cancer Survivor Study. Cancer 2018; 124:3220-3230.

Abstract
BACKGROUND Neuroblastoma survivors may be at elevated risk for psychological impairments because of their young age at diagnosis and neurotoxic treatment, but this is not well described. METHODS A total of 859 ≥5-year survivors of neuroblastoma younger than 18 years (diagnosed in 1970-1999), who had a median age at diagnosis of 0.8 years (range: 0.0-7.3 years) and a median follow-up of 13.3 years (range: 8.0-17.9 years), were compared with 872 siblings of childhood cancer survivors who were younger than 18 years with the parent-reported Behavior Problem Index (BPI) for psychological functioning. Age- and sex-adjusted multivariate log-binomial models were used to identify factors associated with impairment in BPI domains (scores worse than the sibling 10th percentile). The impact of psychological impairment on educational outcomes was examined among survivors. RESULTS Compared with siblings, neuroblastoma survivors had an increased prevalence of impairment in the domains of anxiety/depression (19% vs 14%; P = .003), headstrong behavior (19% vs 13%; P < .001), attention deficits (21% vs 13%; P < .001), peer conflict/social withdrawal (26% vs 17%; P < .001), and antisocial behavior (16% vs 12%; P = .01). Common treatment exposures (vincristine, cisplatin, and retinoic acid) were not associated with impairment. Having 2 or more chronic health conditions predicted impairment in 4 domains (P < .001). Specifically, pulmonary disease predicted impairment in all 5 domains (P ≤ .004). Endocrine disease (P ≤ .004) and peripheral neuropathy (P ≤ .02) each predicted impairment in 3 domains. Psychological impairment was associated with special education service usage and educational attainment less than college. CONCLUSIONS Neuroblastoma survivors are at elevated risk for psychological impairment, which is associated with special education service usage and lower adult educational attainment. Those with chronic health conditions may represent a high-risk group for targeted screening and intervention. Cancer 2018. © 2018 American Cancer Society.

Abstract
Today, children are surviving pediatric cancer at unprecedented rates, making it one of modern medicine's true success stories. However, we are increasingly becoming aware of several deleterious effects of cancer and the subsequent "cure" that extend beyond physical sequelae. Indeed, survivors of childhood cancer commonly report cognitive, emotional, and psychological difficulties, including attentional difficulties, anxiety, and posttraumatic stress symptoms (PTSS). Cognitive late- and long-term effects have been largely attributed to neurotoxic effects of cancer treatments (e.g., chemotherapy, cranial irradiation, surgery) on brain development. The role of childhood adversity in pediatric cancer - namely, the presence of a life-threatening disease and endurance of invasive medical procedures - has been largely ignored in the existing neuroscientific literature, despite compelling research by our group and others showing that exposure to more commonly studied adverse childhood experiences (i.e., domestic and community violence, physical, sexual, and emotional abuse) strongly imprints on neural development. While these adverse childhood experiences are different in many ways from the experience of childhood cancer (e.g., context, nature, source), they do share a common element of exposure to threat (i.e., threat to life or physical integrity). Therefore, we argue that the double hit of early threat and cancer treatments likely alters neural development, and ultimately, cognitive, behavioral, and emotional outcomes. In this paper, we (1) review the existing neuroimaging research on child, adolescent, and adult survivors of childhood cancer, (2) summarize gaps in our current understanding, (3) propose a novel neurobiological framework that characterizes childhood cancer as a type of childhood adversity, particularly a form of early threat, focusing on development of the hippocampus and the salience and emotion network (SEN), and (4) outline future directions for research.

Abstract
Objective: This study aimed to evaluate neuropsychological consequences in survivors of childhood brain tumor. Method: A case-control study was conducted over a period of 4 months in a tertiary referral center in Kuala Lumpur, Malaysia. Fourteen survivors of childhood brain tumor aged 7–18 years, who were off-treatment for at least 1 year and were in remission, and 31 unrelated healthy controls were recruited. The median age at diagnosis was 8.20 years (range: 0.92–12.96 years). The diagnoses of brain tumors were medulloblastoma, germ cell tumor, pineocytoma, pilocystic astrocytoma, suprasellar germinoma, and ependymoma. Eleven survivors received central nervous system irradiation. Seven tasks were selected from the Amsterdam Neuropsychological Tasks program to evaluate alertness (processing speed), and major aspects of executive functioning, such as working memory capacity, inhibition, cognitive flexibility, and sustained attention. Speed, stability and accuracy of responses were the main outcome measures. Results: Survivors of childhood brain tumor showed statistically significant poorer performance on all tasks compared to healthy controls. Both processing speed and accuracy were impaired in the survivors, in particular under more complex task conditions. The survivors demonstrated deficits in alertness, sustained attention, working memory capacity, executive visuomotor control, and cognitive flexibility. Longer duration off treatment appeared to be correlated with poorer alertness, memory capacity, and inhibition. Conclusion: Survivors of childhood brain tumor in our center showed impaired neuropsychological functioning. Development of less toxic treatment protocols is important to prevent late effects of cognitive deficits in survivors of childhood brain tumor.

Abstract
Advances in cancer treatments have led to substantially improved survival for patients with cancer. However, many patients experience changes in cognition as a side effect of both cancer and cancer treatment. This occurs with both central nervous system (CNS) tumors and non-CNS tumors and in both children and adults. Studies of patients with non-CNS cancer have shown that cancer-related cognitive impairment (CRCI), which can include changes in memory, executive function, attention, and processing speed, occurs in up to 30% of patients prior to any treatment and in up to 75% of patients during treatment. A subset of patients with non-CNS and CNS cancer appear to be at higher risk for CRCI, so much research has gone into identifying who is vulnerable. Risk factors for CRCI in adults include cognitive reserve, age, genetic factors, and ethnicity; risk factors for children include genetic factors, female sex, younger age at diagnosis, chemotherapy dose, and both dose and field size for radiation. Although the field has made substantial strides in understanding and treating CRCI, more research is still needed to improve outcomes for both pediatric and adult cancer survivors.

Abstract
With the increase of survival rates of pediatric cancer patients, the number of children facing potential cognitive sequelae has grown. Previous adult studies suggest that white matter (WM) microstructural changes may contribute to cognitive impairment. This study aims to investigate WM microstructure in childhood bone and soft tissue sarcoma. Differences in (micro-)structure can be investigated using diffusion MRI (dMRI). The typically used diffusion tensor model (DTI) assumes Gaussian diffusion, and lacks information about fiber populations. In this study, we compare WM structure of childhood bone and soft tissue sarcoma survivors (n = 34) and matched controls (n = 34), combining typical and advanced voxel-based models (DTI and NODDI model, respectively), as well as recently developed fixel-based models (for estimations of intra-voxel differences, apparent fiber density [AFD] and fiber cross-section [FC]). Parameters with significant findings were compared between treatments, and correlated with subscales of the WAIS-IV intelligence test, age at diagnosis, age at assessment and time since diagnosis. We encountered extensive regions showing lower fractional anisotropy, overlapping with both significant NODDI parameters and fixel-based parameters. In contrast to these diffuse differences, the fixel-based measure of AFD was reduced in the cingulum and corpus callosum only. Furthermore, AFD of the corpus callosum was significantly predicted by chemotherapy treatment and correlated positively with time since diagnosis, visual puzzles and similarities task scores. This study suggests altered WM structure of childhood bone and soft tissue sarcoma survivors. We conclude global chemotherapy-related changes, with particular vulnerability of centrally located WM bundles. Finally, such differences could potentially recover after treatment.

Abstract
PURPOSE/OBJECTIVES To assess change in specific cognitive processes during treatment with chemotherapy only among children with acute lymphoblastic leukemia (ALL).
. DESIGN A prospective, repeated measures design.
. SETTING Pediatric oncology treatment centers at Banner-University Medical Center Tucson/Banner Children's-Diamond Medical Center (University of Arizona) and Texas Children's Cancer and Hematology centers (Baylor College of Medicine) in Houston.
. SAMPLE 71 children with ALL, with a mean age of 6.18 years at the time of diagnosis.
. METHODS Using mixed-effects latent growth curve modeling with time since diagnosis as a fixed effect, age-adjusted standardized measures of working memory, processing speed, executive function, and attention were obtained and repeated about one and two years later. A subsample was tested for academic achievement at the end of treatment.
. MAIN RESEARCH VARIABLES Verbal working memory, visual spatial memory, processing speed, academic achievement, age, and gender.
. FINDINGS A significant main effect was observed for age at diagnosis on decline in verbal working memory during treatment. Planned contrasts revealed greater decline among children who were diagnosed when aged younger than five years compared to those diagnosed when aged five years or older. Decline in verbal working memory and achievement in letter-word identification and calculation skills were associated, and decline in spatial memory was associated with calculation. A main effect of gender was observed on processing speed, with female patients showing greater decline than male patients.
. CONCLUSIONS Findings from this study may guide the timing of interventions that could improve school achievement among survivors.
. IMPLICATIONS FOR NURSING Children undergoing treatment for ALL may experience issues with verbal working memory and increased difficulty in school. Nurses are in a position to refer parents and children to school resources for additional academic support.

Abstract
The aim of the study was to evaluate the long-term neurodevelopmental consequences of currently applied acute lymphoblastic leukemia (ALL) therapy containing chemotherapy alone or combined with 12 Gy radiotherapy. Seventy-nine children aged 6.3-21.7 years diagnosed with ALL and treated according to ALL IC-BFM 2002 have been studied. The control group consisted of 23 children newly diagnosed with ALL. We assessed subcortical gray matter volume using automatic MRI segmentation and cognitive performance to identify differences between three therapeutic schemes and patients prior to treatment. Irradiated patients had smaller selected subcortical volumes than those treated with chemotherapy alone and than the controls, while the chemotherapy group had similar volumes as the control one. In neurocognitive assessment, irradiated children performed worse in major domains than the control group. There were no significant results for patients after high dose chemotherapy without radiotherapy. There was a significant relationship between full scale IQ together with verbal learning and volumes of hippocampus, amygdala, and pallidum. In all children treated for ALL, both decreased volume of selected subcortical structures and cognitive impairment were observed, especially in children who were irradiated.

Abstract
INTRODUCTION Subtle neurocognitive deficits have been recently observed in Acute Lymphoblastic Leukemia (ALL) survivors. AIM We aim to assess the neurocognitive functions of ALL survivors who had been treated with chemotherapy only using two different protocols, and to identify treatment-related risk factors. PATIENTS AND METHODS We carried a multicenter study involving 3 pediatric oncology centers on 100 children who were treated for ALL. Fifty patients were treated by the modified Children's Cancer Group (CCG) 1991 protocol with low dose methotrexate and 50 children were treated by Total XV protocol with high dose methotrexate. Fifty healthy children were included as a control group. Psychometric assessment using Arabic version of Wechsler intelligence scale for children (WISC III) was performed for all patients and controls. RESULTS Patients had significantly lower mean full scale IQ, performance IQ and verbal IQ than controls. Patients ≤ 5 years at diagnosis had significantly lower mean full scale IQ and performance IQ than patients>5 years at diagnosis, while the verbal IQ showed no significant difference between both age groups. Female patients had significantly lower mean full scale IQ, performance IQ and verbal IQthan males. Patients who received Total XV protocol with high dose methotrexate had significantly lower mean full scale IQ, performance IQ and verbal IQ than patients who received modified CCG 1991 protocol with low dose methotrexate. CONCLUSIONS CNS directed chemotherapy might appear to affect neurocognitive functions in children with ALL, which is more significant in young children at diagnosis, in girls and in those receiving high dose methotrexate.

The Effect of Atorvastatin on Vascular Function and Structure in Young Adult Survivors of Childhood Cancer: A Randomized, Placebo-Controlled Pilot Clinical Trial. J Adolesc Young Adult Oncol 2017; 8:442-450.

Abstract
Purpose: Many adult survivors of childhood cancer are at high-risk of developing cardiovascular disease. Cancer therapy may cause damage to the vascular endothelium, thereby initiating atherosclerosis. Atorvastatin has been shown to improve endothelial function independent of reducing cholesterol, as well as reduce/slow arterial stiffness and thickening, yet has never been studied in childhood cancer survivors (CCS). Methods: Twenty-seven young adult (age 26.8 ± 6.2 years) survivors of childhood acute lymphoblastic leukemia or Non-Hodgkin's lymphoma were randomly assigned (1:1) 40 mg/day of atorvastatin or placebo for 6 months. Brachial artery flow-mediated dilation (FMD), small artery reactive hyperemia index (RHI), arterial stiffness, and carotid artery elasticity/thickness were assessed. Results: Fifteen participants completed the trial. No significant treatment effect for any vascular outcomes was observed at 6 months; however, a significant decrease in peak FMD (-3.0 [95% confidence interval [CI]: -5.3, -0.7]) and a trending significant decrease in RHI (-0.3 [95% CI: -0.62, 0.01]) was observed in the placebo group, resulting in a trend toward a treatment effects (p < 0.10). No effect on arterial stiffness, carotid arterial elasticity, or thickness was observed. Conclusion: Six months of atorvastatin treatment did not improve endothelial function or arterial stiffness in young adult CCS. While a trend toward an improvement in endothelial function was present, findings should be interpreted with caution owing to the small number of evaluable participants and subsequent lack of sufficient power. Further research in a larger sample size is needed to fully elucidate the effects of atorvastatin on vascular function. Trial registered at clinicaltrials.gov as NCT01733953.

Abstract
BACKGROUND Acute lymphoblastic leukemia is the most common pediatric cancer, and survival approaches 90%. Acute lymphoblastic leukemia survivors are more likely than healthy peers or siblings to experience academic underachievement, yet little is known about neurocognitive predictors of academic outcomes. OBJECTIVES Objectives were to compare neurocognitive abilities to age-adjusted standardized norms, examine change over time in neurocognitive abilities, and establish neurocognitive predictors of academic outcomes. METHODS Seventy-one children were followed over the course of therapy. Cognitive abilities were assessed during induction when the child was in remission (baseline) and annually for 3 years (years 1, 2, and 3). Reading and mathematics abilities were assessed at year 3. RESULTS Fine motor dexterity was significantly below age-adjusted norms at all data points but showed improvement over time. Baseline visual-motor integration was within the reference range but significantly declined by year 3, and mean scores at years 2 and 3 were significantly below age-adjusted norms. Verbal short-term memory was significantly below age-adjusted norms at all assessments. Visual-motor integration predicted reading and mathematics abilities. Verbal short-term memory predicted reading abilities, and visual short-term memory predicted mathematics abilities. CONCLUSIONS Central nervous system-directed therapy is associated with specific neurocognitive problems. Visual-spatial skills and verbal and visual short-term memory predict academic outcomes. IMPLICATIONS FOR PRACTICE Early assessment of visual-spatial perception and short-term memory can identify children at risk of academic problems. Children who are at risk of academic problems could benefit from a school-based individual educational program and/or educational intervention.

Abstract
PURPOSE To challenge the view that the dose of folinic acid rescue after high-dose methotrexate (MTX) has no significance in the prevention of neurotoxicity and to present the minority view that neurotoxicity can be prevented by an adequate dose of folinic acid, without compromising treatment results. Several fallacies that led to the misunderstanding of post MTX neurotoxicity are presented. METHODS Data mining using search engines was used to find relevant publications, and an e-mail survey of more than 60 authors of articles in this field was performed. All relevant articles identified were read in their entirety. RESULTS Examples of clinical studies with neurotoxicity following inadequate rescue are given. Some studies demonstrated no neurotoxicity when adequate doses of folinic acid rescue were started 24-36 h after the start of HDMTX rescue even after mega doses of MTX. Rescue started after 42 h was associated with neurotoxicity except in patients with low serum MTX levels after 24 and 36 h. ALL protocols with neurotoxicity, especially BFM-like protocols, are presented. Protocol is reported in which single protocol changes prevented neurotoxicity. CONCLUSIONS From the published data, when folinic acid rescue is given in a sufficiently high enough dose and is started 24-36 h after the beginning of the methotrexate exposure, and virtually all forms of post MTX neurotoxicity can be prevented without compromising therapeutic results.

Abstract
Cognitive late-effects have been identified in patients treated with chemotherapy-only protocols for childhood acute lymphoblastic leukemia (ALL), yet the underlying neuropathology is not well understood. This review synthesized recent findings from eight articles investigating the relationship between neurocognitive and neuroimaging outcomes for patients treated for ALL with chemotherapy-only protocols. Reported cognitive domains, imaging methods, and neuroanatomy examined were variable. Despite this, 62.5% (n = 5) of the reviewed studies found a significant relationship between cognitive and imaging outcomes. Greater understanding of the effects of treatment on neuroanatomy and cognitive outcomes is critical for proactively managing ALL cognitive late-effects. Research directions are suggested.

Abstract
Though the treatment of pediatric cancers has come a long way, acute and chronic effects of cancer are still affecting the life of many children. These effects may be caused not only by the malignancy itself but also by the interventions used for the purpose of treatment. This article focuses primarily on the indirect effects of pediatric cancers and their treatment on the central and peripheral nervous system. Chemotherapy, radiation, and stem cell transplantation cause an immune-compromised state and place the patient at risk of infection, the leading cause of mortality in pediatric cancer. The underlying cancer and the treatments also cause neurovascular changes that may lead to neurological sequelae immediately or many years in the future. Chemotherapy and radiation have both immediate and long-term neurotoxic effects on the central and peripheral nervous system. Cancers may also trigger an immune response that damages nervous system components, leading to altered mental status, seizures, abnormal movements, and even psychosis. Knowledge of these effects can help the practitioner be more vigilant for the signs and symptoms of potential neurological complications during the management of pediatric cancers.

Abstract
INTRODUCTION Survival rates for children with acute lymphoblastic leukemia (ALL) approach 95%. At the same time, there is growing concern that chemotherapy causes alterations in brain development and cognitive abilities. We performed MRI measurements of white and gray matter volume to explore how variation in brain structure may be related to cognitive abilities in ALL survivors and healthy controls. METHODS The sample included 24 male ALL survivors who had completed contemporary treatment 3-11 years prior, and 21 age- and sex-matched controls. Participants were between 8 and 18 years old. Working memory and motor response inhibition were measured with the N-Back and Stop Signal Tasks (SST), respectively. Participants underwent 3T structural MRI to assess white and gray matter volumes overall, lobe-wise, and in cortical and atlas-identified subcortical structures. Mental health was assessed with the Child Behavioral Checklist. RESULTS ALL survivors performed more poorly on measures of working memory and response inhibition than controls. Frontal and parietal white matter, temporal and occipital gray matter volume, and volumes of subcortical white and gray matter structures were significantly reduced in ALL survivors compared with controls. Significant structure-function correlations were observed between working memory performance and volume of the amygdala, thalamus, striatum, and corpus callosum. Response inhibition was correlated with frontal white matter volume. No differences were found in psychopathology. CONCLUSIONS Compared with controls, a reduction in volume across brain regions and tissue types, was detectable in ALL survivors years after completion of therapy. These structural alterations were correlated with neurocognitive performance, particularly in working memory. Confirming these observations in a larger, more representative sample of the population is necessary. Additionally, establishing the time course of these changes-and the treatment, genetic, and environmental factors that influence them-may provide opportunities to identify at-risk patients, inform the design of treatment modifications, and minimize adverse cognitive outcomes.

Abstract
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.

Abstract
INTRODUCTION The aim of this study was to assess the long-term side effects of central nervous system prophylaxis (high-dose chemotherapy alone vs chemotherapy and CNS radiotherapy) according to the ALL IC-BFM 2002. METHODS Thirty-tree children aged 6.7-19.9 years have been studied. The control group consisted of 12 children newly diagnosed with acute lymphoblastic leukemia. We assessed subcortical gray matter volume using automatic MRI segmentation and cognitive performance to identify differences between two therapeutic schemes and patients prior to treatment. RESULTS Patients treated with chemotherapy and CNS radiotherapy had smaller hippocampi than two other subgroups and lower IQ score than patients treated with chemotherapy alone. Both treated groups, whether with chemotherapy only or in combination with CNS radiotherapy, had significantly lower volumes of caudate nucleus and performed significantly worse on measures of verbal fluency in comparison with patients prior to treatment. There were no differences in the mean volumes of total white matter, total gray matter, thalamus, putamen, and amygdala between the studied groups. CONCLUSION In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment was observed, especially in children who received chemotherapy in combination with reduced dose CNS radiotherapy. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment were observed, especially in children who received chemotherapy in combination with CNS radiotherapy.
