Emotional Well-Being of Pediatric Brain Tumor Survivors and Comparison Peers: Perspectives From Children and Their Parents

OBJECTIVE

The aim of this study was to examine the emotional well-being of pediatric brain tumor survivors (PBTS) from the perspective of children's self-reports and parents' reports relative to matched comparison peers (COMP) and their parents. It was hypothesized that PBTS would self-report more depression symptoms, loneliness, and lower self-concept than COMP. We also hypothesized that mothers and fathers of PBTS would report more internalizing symptoms and lower total competence for their children. Age and sex effects were examined in exploratory analyses.

METHODS

Families of 187 PBTS and 186 COMP participated across 5 sites. Eligible children in the PBTS group were 8-15 years of age and 1-5 years post-treatment for a primary intracranial tumor without progressive disease. COMP were classmates matched for sex, race, and age.

RESULTS

PBTS self-reported lower scholastic, athletic, and social competence, but not more depression, loneliness, or lower global self-worth than COMP. Parents of PBTS reported more internalizing symptoms and lower total competence than parents of COMP. With few exceptions, group differences did not vary as a function of child age and sex.

CONCLUSION

PBTS reported diminished self-concept in scholastic, athletic, and social domains, while their parents reported broader challenges with internalizing symptoms and total competence. Discrepancies between self-report and parent report require further study to inform targeted interventions for PBTS. Screening survivors for emotional challenges in follow-up clinic or in school setting may help with the allocation of psychosocial support and services for PBTS and their families.

The Influence of Socioeconomic Status (SES) and Processing Speed on the Psychological Adjustment and Wellbeing of Pediatric Brain Tumor Survivors

Simple Summary

Processing speed (PS) is one of the most impaired functions in pediatric brain tumor survivors (PBTSs) and it has been linked to difficulties in their psychological functioning, together with other non-insult-related risk factors, such as socio-economic status (SES). Given the psychological adjustment difficulties observed in PBTS, the aim of the current study was to explore the relationship between SES and psychological functioning, measured with the Child Behavioral Checklist (CBCL) and the Strengths and Difficulties Questionnaire, and considering the contribution of PS as a mediator. The results demonstrated that the influence of SES on the CBCL total index was mediated by PS. Furthermore, PS was found to have a mediating effect on the SES–internalizing problems relationship but not on the SES–externalizing problems relationship. These findings suggest that PS may be a rehabilitation target to prevent psychological distress and should be addressed, especially for PBTSs who live in a disadvantaged situation.

Abstract

(1) Background: The relationship between processing speed (PS) and psychological adjustment in the healthy population is well established, as is that between low socio-economic status (SES) and psychological distress. While PS is one of the most impaired functions in pediatric brain tumor survivors (PBTSs), previous research has demonstrated that low SES may be a predictor of increased psychosocial risk in PBTSs. Given the psychological adjustment difficulties observed in PBTS, in the current study we aimed to explore the relationship between SES and psychological functioning, considering the contribution of PS as a mediator. (2) Methods: demographic and clinical data of 80 children (age range: 4–17 y.o.) were retrospectively collected. Psychological measures were the parent-compiled versions of the Child Behavioral Checklist (CBCL) and the Strengths and Difficulties Questionnaire (SDQ). Mediation analysis models were performed on psychological measures with and without the inclusion of covariates. (3) Results: The influence of SES on the CBCL total index was mediated by PS. Furthermore, PS was found to have a mediating effect on the relationship between SES and internalizing problems but not on the relationship between SES and externalizing problems. (4) Conclusions: The results suggest that PS may be a rehabilitation target for the prevention of psychological distress and should be addressed especially for PBTSs who live in a disadvantaged situation.

Behavioral outcome among survivors of childhood brain tumor: a case control study

BACKGROUND

Advances in the treatment of childhood brain tumors have significantly improved survival rates. With improved survival rates, long-term treatment-related toxicities have become important, and the resulting complications can affect patients' emotion and behavior. This study aimed to 1) evaluate behavioral outcomes among survivors of childhood brain tumors, 2) compare behavioral outcomes among survivors of childhood brain tumors with survivors of childhood leukemia and healthy children, and 3) determine any demographic, disease, and/or treatment-related factors that could affect the behavioral outcomes of survivors of childhood brain tumors.

METHODS

A comparative cross-sectional study was conducted over a period of 1 year (June 1st, 2018-May 31st, 2019) in two tertiary referral centers in Kuala Lumpur, Malaysia. Thirty-eight survivors of childhood brain tumors aged 6 to 18 years old who had been off-treatment for at least 1 year and were in remission, 38 age- and gender-matched survivors of childhood leukemia who had been off-treatment for at least 1 year and were in remission, and 38 age- and gender-matched unrelated healthy children were recruited. The Child Behaviour Checklist (CBCL) parent report and Youth Self-Report (YSR) questionnaires were used to assess behavioral outcomes.

RESULTS

Survivors of childhood brain tumors showed statistically significantly worse behavioral outcomes than healthy children for social problems and attention problems (p < 0.05, respectively). A significantly worse outcome was found for "social problems" (p < 0.05) in survivors of childhood brain tumors compared to survivors of childhood leukemia. Significant associations were also found between physical disability, visual impairment, education level of survivors, and father's occupation and behavioral outcomes among survivors of childhood brain tumors.

CONCLUSIONS

Survivors of childhood brain tumors in our center showed poor behavioral outcomes for social problems and attention problems. Thus, effective psychosocial support interventions tailored to individual patients as soon as treatment is completed are important to prevent potentially debilitating emotional problems.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Psychosexual development and satisfaction in long-term survivors of childhood cancer: Neurotoxic treatment intensity as a risk indicator

BACKGROUND

Risk factors for impairment in psychosexual development and satisfaction among adult survivors of childhood cancer are poorly understood. The authors compared psychosexual outcomes between survivors and healthy controls, and tested whether at-risk survivors can be identified by 1) treatment neurotoxicity or 2) diagnosis.

METHODS

A total of 144 young adult survivors of childhood cancer and 144 matched controls completed questionnaires regarding psychosexual development, sexual satisfaction, and satisfaction with relationship status. Survivors were aged 20 to 40 years and were 5 to 34 years after diagnosis. Using medical chart data, survivors were divided into non-neurotoxic (48 survivors), low-dose (36 survivors), and high-dose (58 survivors) neurotoxic treatment groups.

RESULTS

Apart from having fewer lifetime sex partners, survivors did not appear to differ from controls. However, survivors of brain tumors and any survivor who received high-dose neurotoxic treatment reported the lowest rates of achieving milestones of psychosexual development, whereas sexual and relationship status satisfaction were found to be related to relationship status. Neurotoxic treatment intensity further distinguished between survivors of brain tumors with and without psychosexual impairment.

CONCLUSIONS

The intensity of neurotoxic treatment may be a valuable indicator of risk for psychosexual impairment relative to diagnosis alone. Health care providers should assess romantic/sexual problems among survivors at risk and make referrals if needed. Cancer 2017;123:1869-1876. © 2017 American Cancer Society.

Positive schemas, psychopathology, and quality of life in children with pediatric cancer: A pilot study

PURPOSE

Research in the area of pediatric oncology has shown that although some children and youth diagnosed with this disease cope adaptively after their diagnosis, others continue to have long-term psychosocial difficulties. The potential mechanisms that may protect against the experience of psychopathology and poor quality of life within this population are not well known. The purpose of this pilot study was to utilize a new comprehensive measure of positive schemas to better understand the relationship between positive schemas, quality of life, and psychopathology, for children on active treatment for cancer.

METHODS

Participants were 22 patients, aged 8-18 years, being treated in a pediatric oncology clinic. Patients and parents completed measures of positive schemas, quality of life, and psychopathology.

RESULTS

The mean age at time of initial diagnosis of the patient sample was 11.6 years. Child-reported positive schemas were significantly related to child-reported child quality of life (r = 0.46, p = 0.03).

CONCLUSIONS

This is the first study to examine positive schemas within a pediatric oncology sample. Future research is needed to further explore facets of positive schemas that may be particularly relevant to child psychological functioning in a pediatric oncology population.

Sexually Abstinent Adolescents

This study was a longitudinal follow-up of 697 early adolescents from 20 schools in Missouri, investigating students who, in 1997, indicated on a survey of sexual attitudes and behaviors that they had not had sexual intercourse. They completed the Reasons for Abstinence Scale (RAS) by identifying those items that were reasons why they had not had sex. In 1999, 18 months later, 568 of the same students were available to complete the RAS again. When the adolescents who remained abstinent in 1999 ( n = 422) were compared with their peers who had become sexually active ( n = 146), the abstinent adolescents (a) were significantly less likely to report consuming alcohol on a regular basis, (b) were significantly more likely to be male, and (c) gave more reasons for being abstinent. However, the adolescents who remained abstinent had a significant drop in the number of reasons for being abstinent over the 18 months.

Social competence in children and young people treated for a brain tumour

PURPOSE

The purposes of this study were to provide a multi-informant assessment of social competence in 8-16-year olds treated for a brain tumour (BT) and then to compare these assessment outcomes to peers.

METHOD

A cross-sectional, mixed (within and between group) design was used to compare a paediatric BT survivor group (n = 33) with an age-matched control group (n = 34) on two multi-informant (self-report, parent, teacher) social competence questionnaires: Social Skills Improvement System (SSIS) and Social Responsiveness Scale (SRS). Demographic factors (age, gender, social economic status (SES), intellectual ability and emotional/behavioural difficulties were investigated as potential non-insult-related risk factors.

RESULTS

Compared to controls, the BT group was reported to have difficulties in social adjustment, interactions and information processing, on both social competence questionnaire measures by parents and teachers, but not self-report. Social competence scores for the BT group were broadly distributed within the normal-severe clinical range, with 40 % of BT survivors scoring in the clinical range for social competence difficulties on the SRS. Lower intellectual ability and emotional/behavioural difficulties accounted for some of the group differences in social competence, but group effects remained once estimated IQ and emotional/behavioural difficulties were controlled for.

CONCLUSIONS

Paediatric BT survivors were reported by parents and teachers to have significant difficulties at all three levels of social competence: adjustment, interaction and information processing. The results highlight the importance of routine assessment in clinic settings for social competence and emotional/behavioural difficulties in BT survivors, to promote early identification and to ensure that survivors are referred for appropriate services and intervention as part of their multi-disciplinary care package.

Social competence in pediatric brain tumor survivors: application of a model from social neuroscience and developmental psychology

Pediatric brain tumor (BT) survivors are at risk for psychosocial late effects across many domains of functioning, including neurocognitive and social. The literature on the social competence of pediatric BT survivors is still developing and future research is needed that integrates developmental and cognitive neuroscience research methodologies to identify predictors of survivor social adjustment and interventions to ameliorate problems. This review discusses the current literature on survivor social functioning through a model of social competence in childhood brain disorder and suggests future directions based on this model. Interventions pursuing change in survivor social adjustment should consider targeting social ecological factors.

Temperament and social behavior in pediatric brain tumor survivors and comparison peers

OBJECTIVE

To examine the role of temperament (i.e., surgency/positive affect, negative affect, and effortful control) in the social behavior of pediatric brain tumor survivors and comparison classmates.

METHODS

Parent-, peer-, and self-report data were collected for 75 children after treatment for a brain tumor, and 67 comparison classmates. Tests of mediation and moderated mediation were run to examine whether effortful control accounted for group differences in social behavior and whether this indirect effect was moderated by surgency/positive or negative affectivity.

RESULTS

Peers described survivors as lower in Leadership-popularity and higher in Sensitivity-isolation and victimization than comparison classmates. Parent and self-report of surgency/positive affect revealed survivors were lower on this dimension. Survivors were rated by parents as demonstrating less effortful control. Effortful control did not consistently account for group differences in social behavior. There was limited evidence of moderated mediation.

CONCLUSIONS

Research on the implications of potential changes in temperament following treatment is warranted.

Parent-child communication and psychological adjustment in children with a brain tumor

BACKGROUND

Internalizing problems, anxiety, depression, withdrawal, and consequent social problems are frequently observed in children with brain tumors. The objective of this work is to describe the relationship between these psychological problems and the type of parent-child communication established about the disease.

PROCEDURES

A group of 64 children surviving a brain tumor (aged 4-18 years) underwent psychological assessment by means of parent reports on the Child Behavior Checklist (CBCL) and the Vineland Adaptive Behavior Scales (VABS). A semi-structured interview with each child and their parents enabled us to classify the method of communication regarding the disease as "avoidance," "ineffective," and "effective." Demographic, clinical, and functional data relating to the disease were also collected.

RESULTS

A significant relationship between the onset of Internalizing problems, withdrawal, anxiety-depression, and social problems and the presence of avoidance or ineffective communication about the disease was observed (P = 0.001, P = 0.001, P = 0.001, and P = 0.01, respectively). These psychological problems did not prove to be associated to demographic or clinical variables; however, they were found to be related to the children's residual functional problems. By contrast, the method of communication proved to be unrelated to clinical or functional variables, but it was associated to demographic variables such as sex and age at assessment.

CONCLUSIONS

Effective (complete, truthful, consistent, comprehensible, gradual and continuous, and tailored) communication to the child about his/her condition proved to be associated with a better psychological outcome.

Late effects of therapy for pediatric brain tumor survivors

Approximately 2 of every 3 of all pediatric patients with brain tumors will be long-term survivors. However, there is a steep cost for pediatric brain tumor survivors, and the group as a whole faces significantly more late effects than many other survivors of pediatric cancers. Most of these effects can be attributed to direct neurologic damage to the developing brain caused by the tumor and its removal, the long-term toxicity of chemotherapy, or the effects of irradiation on the central nervous system. The late effects experienced by childhood brain tumor survivors involve multiple domains. This article will review the significant late effects that occur within the medical, neurocognitive, psychosocial, and economic domains of the survivorship experience. We conclude by discussing how the late effects in different domains often coexist and can create a complex set of obstacles that pose significant challenges for a survivor of a pediatric brain tumor on a daily basis.

Specialized Summer Camp for Children with Cancer: Social Support and Adjustment

The purpose of this study was to assess the types of social support received by children attending a week-long residential summer camp for children with cancer. Following the camp, families were sent a social support questionnaire (for the child to complete) and the Child Behavior Checklist (for parents to complete). Analyses evaluated children's adjustment rated by parents, support reported by children, and the relationship between adjustment and support. Girls reported receiving more support than boys, and both genders reported receiving more support at camp than children in the general population. Ratings of adjustment were not different from normative data for boys or girls. No relationship was found between adjustment and support. The camp environment is very supportive and may offer forms of support not available in other environments. Research is needed to further understand how camp can be supportive, what factors may affect that support, and how the experience enhances children's quality of life.

A group social skills intervention program for survivors of childhood brain tumors

OBJECTIVE

The purpose of this study was to evaluate the feasibility and preliminary outcomes of a social skills group intervention program for child brain tumor survivors.

METHODS

Participants were 32 survivors (14 females) aged 8-18 years. Medulloblastoma (28%) was the main diagnosis. The intervention consisted of eight 2-hr weekly sessions focused on social skills including friendship making and assertion. Survivors and parents completed measures of social skills, quality of life, behavior and depression, at baseline, pre- and post-intervention, and 6 months later.

RESULTS

Feasibility analyses revealed promising acceptability, retention, recruitment, and treatment fidelity. Significant improvement was found after intervention based on parents' reports of self-control [F(1,27) = 5.97, p <.05], social skills [F(1,28) = 5.70, p <.05], and quality of life [F(1,15) = 17.98, p <.01].

CONCLUSIONS

The intervention is feasible and outcomes based on parental reports provide preliminary support for the efficacy of the program.

Persistent psychosocial problems in children who develop posterior fossa syndrome after medulloblastoma resection

PURPOSE

Posterior fossa syndrome (PFS) occurs in approximately 20% of patients after resection of a tumor from the posterior fossa. Few descriptions of persistent psychosocial consequences exist. We assessed whether the development of PFS is associated with increased risk for emotional, behavioral, and social problems after the cessation of cancer treatment.

PROCEDURES

Medical charts and neuropsychological data from 21 children (range = 6-17 years old, median = 9.8) were reviewed. All participants were survivors of childhood medulloblastoma and had been treated with surgical resection of the tumor, craniospinal radiation, +/- chemotherapy, and had comprehensive neuropsychological evaluations 1-2 years post-treatment. Six of the 21 were diagnosed with PFS. A series of chi-square tests were conducted to determine whether a relationship existed between PFS and clinically significant levels of emotional, behavioral, and social problems as measured by parent-report on the Achenbach Child Behavior Checklist (CBCL) and Conners' Parent Rating Scale-93 (CPRS-93).

RESULTS

Children who developed PFS were significantly more likely to exhibit obsessive-compulsive type (i.e., perfectionistic) behaviors, withdrawal behaviors, social problems, and internalizing problems (all P < 0.05) than those who did not develop PFS. Additionally, children with PFS were more likely to evidence anxious-shy behaviors, attention problems, and somatic complaints, although these differences were not statistically significant.

CONCLUSION

Results from the current preliminary study suggest that PFS may place children at increased risk for emotional, behavioral, and social problems long after completion of their cancer treatment.

Automated segmentation and classification of high throughput yeast assay spots

Several technologies for characterizing genes and proteins from humans and other organisms use yeast growth or color development as read outs. The yeast two-hybrid assay, for example, detects protein-protein interactions by measuring the growth of yeast on a specific solid medium, or the ability of the yeast to change color when grown on a medium containing a chromogenic substrate. Current systems for analyzing the results of these types of assays rely on subjective and inefficient scoring of growth or color by human experts. Here, an image analysis system is described for scoring yeast growth and color development in high throughput biological assays. The goal is to locate the spots and score them in color images of two types of plates named "X-Gal" and "growth assay" plates, with uniformly placed spots (cell areas) on each plate (both plates in one image). The scoring system relies on color for the X-Gal spots, and texture properties for the growth assay spots. A maximum likelihood projection-based segmentation is developed to automatically locate spots of yeast on each plate. Then color histogram and wavelet texture features are extracted for scoring using an optimal linear transformation. Finally, an artificial neural network is used to score the X-Gal and growth assay spots using the extracted features. The performance of the system is evaluated using spots of 60 images. After training the networks using training and validation sets, the system was assessed on the test set. The overall accuracies of 95.4% and 88.2% are achieved, respectively, for scoring the X-Gal and growth assay spots.

Behavioral and Social Outcomes in Adolescent Survivors of Childhood Cancer: A Report From the Childhood Cancer Survivor Study

Purpose

Adolescents, regardless of medical history, may face behavioral and social challenges. Cancer and related treatments represent additional challenges for teens navigating the transition from childhood to adulthood. This study was conducted to evaluate behavioral and social outcomes of adolescent childhood cancer survivors using data from the Childhood Cancer Survivor Study.

Patients and Methods

We evaluated 2,979 survivors and 649 siblings of cancer survivors to determine the incidence of difficulty in six behavioral and social domains (depression/anxiety, headstrong, attention deficit, peer conflict/social withdrawal, antisocial behaviors, and social competence). Outcomes were determined by calculating parent-reported scores to questions from the behavior problem index.

Results

Survivors and siblings were similar in age at the time of interview (mean: 14.8, survivors; 14.9, siblings; range, 12 to 17 years). Overall, multivariate analyses showed that survivors were 1.5 times (99% CI, 1.1 to 2.1) more likely than siblings to have symptoms of depression/anxiety and 1.7 times (99% CI, 1.3 to 2.2) more likely to have antisocial behaviors. Scores in the depression/anxiety, attention deficit, and antisocial domains were significantly elevated in adolescents treated for leukemia or CNS tumors when compared with siblings. In addition, survivors of neuroblastoma had difficulty in the depression/anxiety and antisocial domains. Treatments with cranial radiation and/or intrathecal methotrexate were specific risk factors.

Conclusion

Adolescent survivors of childhood cancer, especially those with a history of leukemia, CNS tumors, or neuroblastoma, may be at increased risk for adverse behavioral and social outcomes. Increased surveillance of this population, in combination with development of interventional strategies, should be a priority.

Treatments for astrocytic tumors in children: current and emerging strategies

Strategies for the treatment of childhood cancer have changed considerably during the last 50 years and have led to dramatic improvements in long-term survival. Despite these accomplishments, CNS tumors remain the leading cause of death in pediatric oncology. Astrocytic tumors form the most common histologic group among childhood brain tumors. They are a heterogeneous group that from a practical therapeutic point of view can be subdivided into low-grade astrocytomas (LGA), optic pathway gliomas (OPG), high-grade astrocytomas (HGA), and brainstem gliomas (BSG). This article focuses on the practical application of treatments that lead to long-term survival, improved quality of life, and reduced long-term complications. Improvement in therapy has led to better outcomes for patients with LGA and OPG. Careful follow-up without any treatment is indicated for a small percentage of patients diagnosed with LGA with an indolent course including children with neurofibromatosis type 1 (NF1). Surgery is the main recommended treatment for children with resectable LGA. Radiation therapy is generally recommended for children with progressive LGA, or after failure of chemotherapy, accomplishing tumor control at 10 years in over 60% of patients. Cytotoxic chemotherapy is usually reserved for children who have had treatment failure with surgery and radiation therapy. It is also offered for children who are too young to be treated with radiation or to defer or avoid radiotherapy. Carboplatin and vincristine achieve 5% complete and 28% partial responses but the use of vincristine is criticized due to poor penetration of the CNS. A regimen of tioguanine, procarbazine, mitolactol, lomustine, and vincristine is frequently administered as an alternative to carboplatin and vincristine in LGA. The introduction of temozolomide has allowed better responses, including a 24% complete response rate compared with 0-5% complete response rates with the previous regimens. OPG are usually histologically LGA, and are treated with similar chemotherapy regimens. OPG is the most common type of brain tumor associated with NF1. Tumor growth in some of these patients is slow with no treatment recommended for an extended period of time. The prognosis for children with the remaining types of astrocytomas remains poor. Surgical resection is typically the first step in the treatment of HGA followed in older children by radiation therapy. The data regarding chemotherapy are mixed. Combination chemotherapy before or after radiation, including cisplatin, carmustine, cyclophosphamide, and vincristine or carboplatin, ifosfamide, cyclophosphamide, and etoposide has provided disappointing results. Clinical trials with temozolomide and agents directed against single targets have not shown substantially better results, but it is hoped that currently conducted studies will provide better outcomes. Diffuse intrinsic BSG are among the most difficult-to-treat brain tumors. Surgical treatment is not recommended for diffuse intrinsic BSG and standard radiation therapy is typically given in children aged >3 years. None of the numerous chemotherapy regimens, including temozolomide, has provided a significant response rate or an improvement in survival. It is expected that newer agents affecting multiple targets such as AEE-788 and antineoplastons, and combinations of single-targeted agents with chemotherapy will provide better results. Careful evaluation of histology, location of the tumor, patient age, and consideration of treatment-related morbidity play an important part in selecting between clinical observation, surgery, radiation, chemotherapy, or investigational agents. The goals of treatment for astrocytic tumors should extend well beyond objective responses and increased survival. Improvement of quality of life is an equally important objective of treatment. Radiation therapy and chemotherapy result in serious late toxicities.

Developing a health-related quality of life instrument for childhood brain tumor survivors

OBJECTS

With improved treatment, many childhood brain tumor survivors live through adulthood. A psychometrically sound instrument, which can capture their unique experiences through the lifetime, is needed. This paper documents the development of the Pediatric Functional Assessment of Cancer Therapy-Childhood Brain Tumor Survivor (PedsFACT-BrS) for use with survivors for at least 1 year posttreatment.

METHODS

The PedsFACT-BrS was developed in two phases. In phase I, items were generated via interviewing 20 survivors, 20 caregivers, and 12 clinicians/teachers. In phase II, Rasch analysis and classical test theory were used to evaluate the responses of 46 survivors and 46 caregivers.

CONCLUSION

The 34-item PedsFACT-BrS covers four domains: physical well-being, emotional well-being and illness experiences, social well-being, and brain tumor-specific concerns. Its scalability is supported by Rasch analysis and its content validity and reliability is documented. It is now ready to be validated to other subpopulations across the disease trajectory.

Dietary essential fatty acids and gender-specific behavioral responses in cranially irradiated rats

Specific memory deficits, reduced intellectual processing speed, and a variety of social and behavioral problems have been implicated as long-term effects of cranial radiation therapy (CRT). These deficits are thought to be related to changes in brain cytology and structure associated with microvascular aberrations. N-3 fatty acids may serve as protectants in pediatric patients who receive CRT for brain tumors. Timed-pregnant rat dams were fed one of four diets that were identical in all respects, except for their essential fatty acid content. The dams were placed on these diets at the beginning of the third trimester of gestation and their pups remained on them throughout the study. The rats' behavioral response as judged by acoustic startle response (ASR) and neurocognitive response (performance in a radial maze, RM) were evaluated in relation to diet, gender, and CRT. The following hypotheses were tested: (1) female rats will show greater CRT-induced neurocognitive and behavioral deficits; (2) dietary n-3 fatty acids will diminish CRT-induced neurocognitive and behavioral deficits; (3) gender-specific differences would be dampened by n-3 fatty acids in the diet. All three hypotheses were partially supported. These findings are discussed in light of the potential neuroprotective effects of n-3 fatty acids.

Behavioral and educational limitations after chemotherapy for childhood acute lymphoblastic leukemia or Wilms tumor

BACKGROUND

The improved prognosis of childhood cancer makes monitoring of functional outcome important. The purpose of this study was to evaluate behavioral and educational functioning in survivors of childhood acute lymphoblastic leukemia (ALL) or a Wilms tumor. In this study, children with ALL received central nervous system directed chemotherapy without cranial irradiation.

METHODS

In a multicenter study, behavioral functioning and school performance was examined in 199 children age 4 to 18. Sixty-four children were at least 1 year from finishing treatment with chemotherapy for ALL (n = 28) or a Wilms tumor (n = 36). They were compared with siblings (n = 37) and with a control group of healthy schoolchildren (n = 98).

RESULTS

A moderately increased risk of behavioral and educational problems was found in children with ALL but not in children with Wilms tumor. School performance was poorer in children with ALL attending primary school compared with same-age peers; however, the rate of utilization of special education services was low. Teacher-rated behavior and mathematics performance was correlated with attention function in children with ALL. An excess of problem behavior and underperformance at school was found in the ALL high-risk group compared with the standard-risk group. No differences were found between siblings and controls.

CONCLUSION

Evidence is provided of subtle but significant behavioral and educational problems in survivors of childhood ALL, but no dysfunctions in survivors of a Wilms tumor. Careful follow-up of children with ALL treated with chemotherapy only is warranted.

Factors associated with emotional and behavioural problems among school age children of breast cancer patients

To identify factors linked with emotional and behavioural problems in school age (6- to 17-year-old) children of women with breast cancer. Reports of children's emotional and behavioural problems were obtained from patient mothers, their healthy partners, the children's teacher and adolescents using the Child Behaviour Checklist and Mental Health subscale of the Child Health Questionnaire. Parents reported on their own level of depression and, for patients only, their quality of life. Family functioning was assessed using the Family Assessment Device and Cohesion subscale of the Family Environment Scale. Using a cross-sectional within groups design, assessments were obtained (N=107 families) where the patients were 3-36 months postdiagnosis. Risk of problems in children were linked with low levels of family cohesion, low affective responsiveness and parental over-involvement as reported by both child and mother. Adolescents reported family communication issues, which were associated with externalising behaviour problems. Maternal depression was related to child internalising problems, particularly in girls. Whether the mother was currently on or off chemotherapy was not associated with child problems nor was time since cancer diagnosis. These findings held across child age. Where mothers have early stage breast cancer, a substantial minority of their school-aged children have emotional and behavioural problems. Such cases are characterised by the existence of maternal depression and poor family communication, rather than by the mother's treatment status or time since diagnosis. Targeted treatments, which focus on maternal depression and family communication may benefit the children and, through improved relationships, enhance the patients' quality of life.

School experiences after treatment for a brain tumour

BACKGROUND

Children surviving a brain tumour face major difficulties including learning problems, lengthy school absences and psychosocial problems, all of which can impact on school functioning. Our aims were to provide information for parents and teachers about the skills and resources of this group. Specifically, we aimed to: describe the special educational needs of these children; document the impact of diagnosis and treatment on school attendance; compare parent and teacher assessments of social, emotional and behavioural difficulties.

METHODS

Forty families agreed to participate (response rate = 58.82%). The children (19 males and 21 females) were aged from 6 to 16 years and had completed treatment at least 2 years previously (range = 2 years-12 years 5 months). Questionnaires (Strengths and Difficulties and school experience) were completed by mothers and teachers.

RESULTS

Survivors were experiencing a wide range of physical, learning and interpersonal difficulties, according to parent and teacher reports. Almost half the children (n = 19) had ongoing neurological problems that were significant enough to require special help at school. Literacy and numeracy were the most common learning difficulties. Parents also rated brain tumour survivors as having more behavioural and emotional problems than would be expected from population norms. For example, survivors were rated as having more Total Difficulties (t = 6.86, P < 0.001), Emotional Symptoms (t = 8.82, P < 0.001), Hyperactivity (t = 2.25, P = 0.03), Peer Relationship Problems (t = 7.58, P < 0.001) and poorer Pro-social Behaviour (t = -3.34, P = 0.002) than would be expected from population norms. These problems were also seen to be having a significant impact on the child's functioning (t = 3.95, P < 0.001). Teachers rated these problems as less serious than parents.

CONCLUSION

These children experience significant problems in school some time after diagnosis and when they are considered medically cured. Closer school-hospital liaison is essential to maximize integration and achievement in these children.

Brain tumors in children and adolescents: cognitive and psychological disorders at different ages

Cognitive and psychological disorders are among the most frequently observed sequelae in brain tumor survivors. The goal of this work was to verify the presence of these disorders in a group of children and adolescents diagnosed with brain tumor before age 18 years, differentiate these disorders according to age of assessment, identify correlations between the two types of impairments and define possible associations between these impairments and clinical variables. The study involved 76 patients diagnosed with brain tumor before age 18 years. Three age groups were formed, and all the patients received a standardized battery of age-matched cognitive and psychological tests. According to our findings, all three groups present with cognitive and psychological-behavioral disorders. Their frequency varies according to age of onset and is strongly associated to time since diagnosis. The performance intelligence quotient (PIQ) was more impaired than the verbal intelligence quotient (VIQ). Internalizing problems, withdrawal and social problems were the most frequent psychological disorders. Correlations were found between cognitive impairment and the onset of the main psychological and behavioral disorders. These findings are relevant as they point out the long-term outcome of brain tumor survivors. Hence, the recommendation to diversify psychological interventions and rehabilitation plans according to the patients' age.

Serial Evaluation of Academic and Behavioral Outcome After Treatment With Cranial Radiation in Childhood

Purpose

To evaluate academic and behavioral outcome in radiated survivors of posterior fossa (PF) tumors.

Patients and Methods

Fifty-three patients (36 males) treated for malignant PF tumors were seen for evaluation of academics and/or behavioral functioning. Forty-six patients were treated for medulloblastoma, and seven patients were treated for ependymoma. Fourteen patients were treated with reduced-dose cranial radiation, and 34 patients were treated with standard-dose cranial radiation (dose was not available for four patients). All patients received an additional boost to the PF. One patient was treated with PF radiation only. Standardized achievement tests and behavioral questionnaires were administered at different times after diagnosis for each child. First, the influence of demographic and medical variables on outcome was examined. Second, the rate of change in scores was determined using mixed model regression for patients seen for serial assessment.

Results

The presence of hydrocephalus was related to poorer academics, but outcome was not related to radiation dose, extent of surgery, or treatment with chemotherapy. Younger age predicted poor reading ability and lower parent rating of academic achievement. Children's performance declined for spelling, mathematics, and reading. Significant declines were also evident in parent and teacher's ratings of academic ability. Behavioral functioning was generally not related to medical and demographic variables, and few clinically significant problems in externalizing behavior were evident. Increases in social and attention problems emerged over time.

Conclusion

Cranial radiation is associated with declines in academic ability, social skills, and attention. However, neither psychological distress nor behavior problems were a significant concern for this sample.

Psychosocial Functioning in Pediatric Cancer

OBJECTIVE

To describe the emergence of pediatric psycho-oncology and to summarize research on psychosocial aspects of childhood cancer and survivorship.

METHODS

To review research into illness communication and informed consent, procedural pain, late effects, psychological distress, coping and adjustment, and special risk populations. Methodological challenges, appropriate methodology, and directions for future research are discussed.

RESULTS

The past 30 years have seen change from avoidance of communication about cancer to an emphasis on straightforward discussion of diagnosis and prognosis. Behavioral research has led to interventions to reduce procedural distress. Late effects have been observed in social functioning. Although average levels of distress in survivors of pediatric cancer are typical, subsets of more vulnerable patients and family members exist. Factors predicting positive and negative coping have been identified.

CONCLUSIONS

As the numbers of pediatric cancer survivors increase, psychosocial researchers will be better able to conduct longitudinal studies not only of adjustment and its predictors but also of the impact of the emerging medical treatments and interventions to ameliorate late effects of treatment. Additional funding, improving methodology, and multi-institutional cooperation will aid future pediatric psycho-oncology investigators.

Neuropsychological functioning after surgery in children treated for brain tumor

OBJECTIVE

To describe the neuropsychological functioning of children treated with surgery only for localized brain tumors in Dana-Farber Cancer Institute Protocol 92-077. Subsequent reports will describe the neuropsychological functioning of children treated with surgery and stereotactic radiation therapy on Dana-Farber Cancer Institute 92-077.

METHODS

The intellectual functioning of 106 patients was evaluated within 3 months after surgery. An in-depth assessment of the neuropsychological functioning, including an impairment index, was conducted for a subset of 77 school-age children (6-16 yr old) across six functional domains. Descriptive statistics were generated; binomial distribution analyses were performed to assess whether the proportion of individuals with impaired performance on each measure exceeded normative expectations. The impairment index assessed whether poor performance was attributable to a few children or reflected the performance of the cohort as a whole.

RESULTS

Although the Full Scale IQ was within normative expectations, the Verbal IQ was higher than the Performance IQ with 45% of individuals showing a significant discrepancy (P < 0.01) between these scales. There was an increased prevalence of poor performance for measures of motor output, verbal memory, and visuospatial organization. The distribution of the impairment index indicated moderate impairment across the school-age cohort rather than severe impairment in a few patients.

CONCLUSION

The results document a moderate level of neuropsychological morbidity among children with brain tumors before stereotactic radiation therapy, presumably referable to the tumor itself and the surgery. The extent to which stereotactic radiation therapy may increase this burden will be assessed in follow-up studies evaluating the longitudinal neuropsychological data.

Survivors of childhood brain tumors: behavioral, emotional, and social adjustment

This paper reviews the literature on the psychological adjustment and quality of life in children who survive brain tumors. A total of 31 studies were reviewed. Findings are discussed in terms of the rates of general psychological adjustment, internalizing behavior problems, externalizing behavior problems, social competence, correlates or predictors of adjustment, and quality of life among survivors. Although these survivors appear to be at risk for compromised social competence and long-term quality of life, reports in the literature on rates of psychological adjustment in this population vary widely. Limitations in the current literature are discussed including inadequate assessment techniques, lack of appropriate comparison groups, and small sample sizes. Directions for future research are offered.

The school experience of the child with cancer

OBJECTIVE

To review literature investigating school absence, behaviour problems and social relationships of children with cancer on return to school. Additionally, we reviewed interventions aimed at promoting successful school re-entry for children with cancer, and increasing classmates and teachers understanding of childhood cancer.

METHODS

Electronic searches were used to identify studies examining the effects of school re-entry on children with cancer.

RESULTS AND CONCLUSIONS

School absences are higher for children with cancer than healthy children and those with other chronic conditions. Although there is mixed evidence about whether children have significant behavioural problems, studies involving social relationships generally conclude that children with cancer are more sensitive and isolated than peers, according to both peer and teacher report.

Eine Übersicht über kognitiv, behaviorale und psychosoziale Langzeitfolgen nach pädiatrischen Hirntumoren

Zusammenfassung. In diesem Beitrag wird ein Überblick über die kognitiven, behavioralen und psychosozialen Langzeitfolgen bei Kindern und Jugendlichen mit Hirntumoren gegeben. In der Übersicht wird deutlich, daß die kognitiven Leistungen der pädiatrischen Hirntumor-Patienten (insb. nach Radiatio) deutlich stärker beeinträchtigt sind als bei Kindern mit Leukämieerkrankung nach ZNS-Bestrahlung. Verbunden damit, aber auch aufgrund der großen Häufigkeit von Verhaltensauffälligkeiten, wird die schulische Reintegration als schwierig beschrieben. Die massiven kognitiven Beeinträchtigungen und Verhaltensauffälligkeiten der Hirntumor-Kinder machen die Notwendigkeit der Konzeption und Evaluation von Rehabilitations- und Beratungsmaßnahmen für die betroffenen Kinder und ihre Eltern deutlich.

Effect of ionizing radiation on the human brain: white matter and gray matter T1 in pediatric brain tumor patients treated with conformal radiation therapy

OBJECTIVE

To test a hypothesis that fractionated radiation therapy (RT) to less than 60 Gy is associated with a dose-related change in the spin-lattice relaxation time (T1) of normal brain tissue, and that such changes are detectable by quantitative MRI (qMRI).

METHODS

Each of 21 patients received a qMRI examination before treatment, and at several time points during and after RT. A map of brain T1 was calculated and segmented into white matter and gray matter at each time point. The RT isodose contours were then superimposed upon the T1 map, and changes in brain tissue T1 were analyzed as a function of radiation dose and time following treatment. We used a mixed-model analysis to analyze the longitudinal trend in brain T1 from the start of RT to 1 year later. Predictive factors evaluated included patient age and clinical variables, such as RT dose, time since treatment, and the use of an imaging contrast agent.

RESULTS

In white matter (WM), a dose level of greater than 20 Gy was associated with a dose-dependent decrease in T1 over time, which became significant about 3 months following treatment. In gray matter (GM), there was no significant change in T1 over time, as a function of RT doses < 60 Gy. However, GM in close proximity to the tumor had an inherently lower T1 before therapy. Neither use of a contrast agent nor a combination of chemotherapy plus steroids had a significant effect on brain T1.

CONCLUSION

Results suggest that T1 mapping may be sensitive to radiation-related changes in human brain tissue T1. WM T1 appears to be unaffected by RT at doses less than approximately 20 Gy; GM T1 does not change at doses less than 60 Gy. However, tumor appears to have an effect upon adjacent GM, even before treatment. Conformal RT may offer a substantial benefit to the patient, by minimizing the volume of normal brain exposed to greater than 20 Gy.

A clinical profile to predict decision making, risk behaviors, clinical status, and health-related quality of life for cancer-surviving adolescents. Part 1

The purpose of this two-part series is to describe a multifactorial model of clinical factors predicting decision-making quality, risk behaviors, clinical status, and health-related quality of life for cancer-surviving adolescents. This model was developed as a clinical profile to help health professionals in better identifying cancer-surviving adolescents at highest risk for substance use. Findings in the literature and results from the program of research by the author are presented to support the conceptualization of the model. In part 1, support for the antecedent predictors, both primary and secondary factors, is presented. Part 2 addresses decision making as a mediator, risk motivation as a moderator, and the expected outcomes related to risk behaviors, clinical status, and quality of life. In addition to describing the first part of the clinical profile in part 1, the background, theoretical basis of the model, and definitions of the model constructs also are provided.

Social problem solving in children with acquired brain injuries

OBJECTIVES

To assess the performance of children with acquired brain injuries (ABIs) on a measure of social problem solving and to examine the relationships between participant characteristics and performance on the Social Knowledge Interview (SKI) and between parent-reported child behavior and performance on the SKI.

DESIGN

Between-group comparisons using correlational analyses, matched pairs t-tests, and analysis of covariance (ANCOVA).

PARTICIPANTS

Thirty-one children 6-12 years old with ABI and 31 control participants, matched on age and sex.

MAIN OUTCOME MEASURE

The SKI, a measure of social problem-solving skills.

RESULTS

Using matched pairs t-tests and ANCOVA, groups were compared on several SKI measures, including the number of unique responses generated for each problem scenario, the quality of those responses, and the ability to select the best response from a set of alternatives. When equated for socioeconomic status (SES), ABI and control participants performed similarly on the SKI; however, a trend for children with ABI to generate more assertive responses was observed. Performance on the SKI was positively correlated with IQ and related to parent-reported adaptive behavior. In children with ABI, performance was also related to primary lesion location and treatment regimen.

CONCLUSIONS

Children with ABI are as capable of judging the appropriateness of behavior and generating response options on an analog measure of social problem solving as were their typically developing peers. However, those individual children with ABI who are more likely to have social problems may be identified by the qualitative aspects of their responses on analog tasks. These findings have implications for the identification of children with social skills deficits following ABI and for the development of effective rehabilitation strategies.

Psychological outcome in children treated for brain tumor

The cognitive and psychosocial functions of 16 children with brain tumor, treated with wholebrain or local radiotherapy, were studied. Fifteen nonirradiated children with acute lymphatic leukemia (ALL) served as a comparison group. Mean Wechsler Intelligence Scale for Children--Revised Full Scale IQ score and mean Visual-Motor Integration Test (Beery VMI) standard score were significantly decreased in the brain tumor group. The Achenbach checklists were filled in by mothers (Child Behavior Checklist, CBCL) and teachers (Teacher's Report Form). Overall adjustment was rated lower in the children with brain tumor. Although most of the children in the ALL group were well adapted, one third of them had low CBCL Social Competence scores relative to nonclinical norms. On a visual analog scale a significantly decreased tempo was assessed by mothers and teachers in the children with brain tumor, and low speed and hypoactivity seemed to limit the majority of these children in school and daily life activities.

A hybrid neural network analysis of subtle brain volume differences in children surviving brain tumors

In the treatment of children with brain tumors, balancing the efficacy of treatment against commonly observed side effects is difficult because of a lack of quantitative measures of brain damage that can be correlated with the intensity of treatment. We quantitatively assessed volumes of brain parenchyma on magnetic resonance (MR) images using a hybrid combination of the Kohonen self-organizing map for segmentation and a multilayer backpropagation neural network for tissue classification. Initially, we analyzed the relationship between volumetric differences and radiologists' grading of atrophy in 80 subjects. This investigation revealed that brain parenchyma and white matter volumes significantly decreased as atrophy increased, whereas gray matter volumes had no relationship with atrophy. Next, we compared 37 medulloblastoma patients treated with surgery, irradiation, and chemotherapy to 19 patients treated with surgery and irradiation alone. This study demonstrated that, in these patients, chemotherapy had no significant effect on brain parenchyma, white matter, or gray matter volumes. We then investigated volumetric differences due to cranial irradiation in 15 medulloblastoma patients treated with surgery and radiation therapy, and compared these with a group of 15 age-matched patients with low-grade astrocytoma treated with surgery alone. With a minimum follow-up of one year after irradiation, all radiation-treated patients demonstrated significantly reduced white matter volumes, whereas gray matter volumes were relatively unchanged compared with those of age-matched patients treated with surgery alone. These results indicate that reductions in cerebral white matter: 1) are correlated significantly with atrophy; 2) are not related to chemotherapy; and 3) are correlated significantly with irradiation. This hybrid neural network analysis of subtle brain volume differences with magnetic resonance may constitute a direct measure of treatment-induced brain damage.

Psychiatric sequelae in seriously ill children and their families

Going through a life-threatening illness as a child or adolescent is a tremendously stressful experience for the entire family. Although the majority of survivors do go on to adjust and function well, some have ongoing problems. These problems include evidence of posttraumatic stress, learning difficulties, depression, and anxiety. Their parents appear to be even more severely affected, possibly because they had a better appreciation at the time of the true dangers posed by the illness and the treatment. Little is yet known about their siblings, although it is clear that the acute stage of illness and treatment effects the entire family. Areas needing study include the long-term sequelae on siblings of survivors, as well as a better understanding of the precipitants and mediators of the problems noted in survivors and parents. Only then can interventions and preventative measures be undertaken and tested. Also needed is a better understanding of the impact of cultural differences on precipitants, mediators, and symptoms.
