Abstract
Intracranial tumors in the first year of life are rare and, in this age group, are the second most common type of pediatric cancer after leukemias. As the more common solid tumor in neonates and infants, they present some peculiarities such as the high incidence of malignancies. Routine ultrasonography made easier to detect intrauterine tumors, but diagnosis can be delayed due to the lack or scarcity of recognizable symptoms. These neoplasms are often very large and highly vascular. Their removal is challenging, and there is a higher rate of morbidity and mortality than seen in older children, adolescents, and adults. They also differ from older children with respect to location, histological features, clinical behavior, and management. Pediatric low-grade gliomas represent 30% of the tumors in this age group and comprise circumscribed and diffuse tumors. They are followed by medulloblastoma and ependymoma. Other non-medulloblastoma embryonal neoplasms, former known as PNETS, are also commonly diagnosed in neonates and infants. Teratomas have an expressive incidence in newborns but decline gradually until the end of the first year of life. Immunohistochemical, molecular, and genomic advances are impacting the understanding and targeting of the treatment of some tumors, but, despite all these advances, the extent of resection remains the most important factor in the prognosis and survival of almost all types of tumors. The outcome is difficult to estimate, and 5-year survival ranges from one-quarter to three-quarters of the patients.

The Influence of Socioeconomic Status (SES) and Processing Speed on the Psychological Adjustment and Wellbeing of Pediatric Brain Tumor Survivors. Cancers (Basel) 2022; 14:cancers14133075. [PMID: 35804846 PMCID: PMC9264789 DOI: 10.3390/cancers14133075] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 06/20/2022] [Accepted: 06/21/2022] [Indexed: 01/27/2023] Open
Abstract
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.

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.

Abstract
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.

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
BACKGROUND Pediatric central nervous system (CNS) tumor survivors are at high risk for numerous late effects including decreased health-related quality of life (HRQOL). Our objective was to summarize studies describing HRQOL in pediatric CNS tumor survivors and compare HRQOL outcomes in studies that included a comparison group. PROCEDURE EMBASE, MEDLINE, and PsychINFO were used to identify relevant articles published until August, 2016. Eligible studies reported outcomes for pediatric CNS tumor survivors diagnosed before age 21, at least 5 years from diagnosis and/or 2 years off therapy and used a standardized measure of HRQOL. All data were abstracted by two reviewers. Random-effects meta-analyses were performed using Review Manager 5.0. RESULTS Of 1,912 unique articles identified, 74 were included in this review. Papers described 29 different HRQOL tools. Meta-analyses compared pediatric CNS tumor survivors to healthy comparisons and other pediatric cancer survivors separately. HRQOL was significantly lower for CNS (n = 797) than healthy comparisons (n = 1,397) (mean difference = -0.54, 95% confidence interval [CI] = -0.72 to -0.35, P < 0.001, I2 = 35%). HRQOL was also significantly lower for CNS (n = 244) than non-CNS survivors (n = 414) (mean difference = -0.56, 95% CI = -0.73 to -0.38, P < 0.00001, I2 = 0%). CONCLUSIONS Pediatric CNS tumor survivors experience worse HRQOL than healthy comparisons and non-CNS cancer survivors. Future HRQOL work should be longitudinal, and/or multisite studies that examine HRQOL by diagnosis and treatment modalities.

Abstract
INTRODUCTION Infantile brain tumours (age < 1 year) are increasingly being diagnosed due to advances in prenatal and perinatal diagnostic imaging. We present here our retrospective study of 64 infant brain tumours that brings to the fore the epidemiology, clinical presentation, pathology and outcome of this unique subset of paediatric brain tumours presenting to two tertiary referral centres in Kolkata in India and Lille in France between the years 1999 and 2014. METHODS Data was retrospectively collected from Kolkata (n = 30) and Lille (n = 34) for patients presenting with infant brain tumours and analysed for factors such as age at presentation, clinical features, gender, location of tumour, pathology, management and outcome. Follow-up was available for all patients. RESULTS Mean age at presentation was 6.8 months at Kolkata and 6.3 months at Lille. More than two-thirds of tumours in both the groups were supratentorial and presented with signs of raised intracranial pressure. There was also a similar proportion of tumours presenting as congenital tumours. At Kolkata, germ cell tumours (n = 7) were the most common while low-grade gliomas (n = 11) formed the largest group at Lille. Kolkata had a higher incidence of high-grade gliomas (n = 5) and PNETs (n = 4) while ATRT (n = 3) and choroid plexus carcinoma (n = 4) were more common at Lille. Surgery was the mainstay of treatment at both centres. CONCLUSION Brain tumours in infants presenting to tertiary centres in Europe and India are challenging to manage and usually have dismal prognosis. These tumours differ markedly in the pathology and, therefore, overall outcome. Surgery forms mainstay of treatment. Radiotherapy is best avoided in this age group.

Abstract
The survival of childhood brain tumors has improved in the past 30 years, but acquired brain injury due to damage caused by tumor invasion and side effects of different treatment modalities frequently occurs. This study focused on residual impairments, health-related quality of life (HRQoL), and emotional and behavioral problems in 2 cohorts of survivors diagnosed and treated for various types of brain tumors. Survivors in the 2004 cohort visited the Erasmus Medical Centre for standardized follow-up between 2003 and 2004, and in the 2014 cohort, between 2012 and 2014. Data of neurologically impairments of all children were extracted from medical records. Parents and survivors filled out questionnaires on quality of life and emotional and behavioral problems. In both cohorts, approximately 55% of the survivors displayed neurologic impairments. In comparison with the healthy reference group, a reduced parent-reported quality of life was found on the Motor, Cognition, and Autonomy (Cohort 2004) scales. Comparison between the cohorts showed that parents in the 2004 cohort reported a higher HRQoL on the Motor and Cognitive functioning scales. In the 2014 cohort, children reported less negative emotions than healthy children. No increase in emotional or behavioral problems were reported by children in both cohorts, whereas parents reported problems in social functioning and isolation related to a delay in emotional development. Children surviving brain tumor treatment have a reduced quality of life. The authors therefore recommend regular screening of HRQoL and emotional and behavioral problems and referral to specific aftercare.

Abstract
Pediatric high-grade astrocytomas (pHGA) and diffuse intrinsic pontine gliomas (DIPG) are devastating malignancies for which no effective therapies exist. We investigated the therapeutic potential of PARP1 inhibition in preclinical models of pHGA and DIPG. PARP1 levels were characterized in pHGA and DIPG patient samples and tumor-derived cell lines. The effects of PARP inhibitors veliparib, olaparib, and niraparib as monotherapy or as radiosensitizers on cell viability, DNA damage, and PARP1 activity were evaluated in a panel of pHGA and DIPG cell lines. Survival benefit of niraparib was examined in an orthotopic xenograft model of pHGA. About 85% of pHGAs and 76% of DIPG tissue microarray samples expressed PARP1. Six of 8 primary cell lines highly expressed PARP1. Interestingly, across multiple cell lines, some PARP1 protein expression was required for response to PARP inhibition; however, there was no correlation between protein level or PARP1 activity and sensitivity to PARP inhibitors. Niraparib was the most effective at reducing cell viability and proliferation (MTT and Ki67). Niraparib induced DNA damage (γH2AX foci) and induced growth arrest. Pretreatment of pHGA cells with a sublethal dose of niraparib (1 μmol/L) before 2 Gy of ionizing radiation (IR) decreased the rate of DNA damage repair, colony growth, and relative cell number. Niraparib (50 mg/kg) inhibited PARP1 activity in vivo and extended survival of mice with orthotopic pHGA xenografts, when administered before IR (20 Gy, fractionated), relative to control mice (40 vs. 25 days). Our data provide in vitro and in vivo evidence that niraparib may be an effective radiosensitizer for pHGA and DIPG.

Abstract
BACKGROUND Cognitive problems can have a negative effect on a person's education, but little is known about cognitive problems in young childhood cancer survivors (survivors). This study compared cognitive problems between survivors and their siblings, determined if cognitive problems decreased during recent treatment periods and identified characteristics associated with the presence of a cognitive problem in survivors. METHODS As part of the Swiss Childhood Cancer Survivor Study, a questionnaire was sent to all survivors, aged 8-20 years, registered in the Swiss Childhood Cancer Registry, diagnosed at age <16 years, who had survived ≥ 5 years. Parent-reported (aged 8-15 years) and self-reported (aged 16-20 years) cognitive problems (concentration, working speed, memory) were compared between survivors and siblings. Multivariable logistic regression was used to identify characteristics associated with cognitive problems in survivors. RESULTS Data from 840 survivors and 247 siblings were analyzed. More often than their siblings, survivors reported problems with concentration (12% vs. 6%; P = 0.020), slow working speed (20% vs. 8%; P = 0.001) or memory (33% vs. 15%; P < 0.001). Survivors from all treatment periods were more likely to report a cognitive problem than were siblings. Survivors of CNS tumors (OR = 2.82 compared to leukemia survivors, P < 0.001) and those who had received cranial irradiation (OR = 2.10, P = 0.010) were most severely affected. CONCLUSION Childhood cancer survivors, even those treated recently (2001-2005), remain at risk to develop cognitive problems, suggesting a need to improve therapies. Survivors with cognitive problems should be given the opportunity to enter special education programs.

Abstract
Diphtheria toxin-like ADP-ribosyltransferases 1 and 5 (ARTD-1, ARTD-5) are poly ADP-ribose enzymes (PARP) involved in non-homologous end-joining (NHEJ), which is the major pathway of double-strand break (DSB) repair. In addition, ARTD-5, or Tankyrase (TNKS), is a positive regulator of the WNT signaling implicated in the development and biological behavior of many neoplasms, such as Medulloblastoma (MB), in which radiotherapy is an essential part of the treatment. The use of radiosensitizing agents may improve the therapeutic index in MB patients by increasing the efficacy of radiotherapy, while reducing toxicity to the neuroaxis. ARTD-5 seems to be a good molecular target for improving the current treatment of MB. In this study, we used the small molecule XAV939, a potent ARTD-5 inhibitor with a slight affinity for ARTD-1, in different human MB cell lines. XAV939 inhibited the WNT pathway and DNA-PKcs in our MB cells, with many biological consequences. The co-administration of XAV939 and ionizing radiations (IR) inhibited MB cells proliferation and clonogenic capacity, decreased their efficacy in repairing DNA damage, and increased IR-induced cell mortality. In conclusion, our in vitro data show that XAV939 could be a very promising small molecule in MB treatment, and these results lay the basis for further in vivo studies with the aim of improving the current therapy available for MB patients.

Neurosurgical treatment of brain tumors in the first 6 months of life: long-term follow-up of a single consecutive institutional series of 30 patients. Childs Nerv Syst 2015; 31:2283-90. [PMID: 26174616 PMCID: PMC4642591 DOI: 10.1007/s00381-015-2792-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2015] [Accepted: 06/09/2015] [Indexed: 11/24/2022]
Abstract
OBJECT The aim of this study is to delineate the long-term results for patients going through surgery for pediatric brain tumors in the first 6 months of life. METHODS Thirty consecutive children (1-182 days old) who underwent primary resection for a brain tumor during the years 1973-2012 were included in this retrospective study on surgical morbidity, mortality rate, academic achievement, and/or work participation. Gross motor function and activities of daily life were scored according to the Barthel index. RESULTS Of the 30 patients, 11 children had surgery in the first 3 months of life (1 to 88 days) and 19 were aged 3 to 6 months (94-182 days) at the time of surgery. The male/female ratio was 1.0 (15/15). No patients were lost to follow-up. Two patients died in the postoperative period (30 days). Another eight patients died during the follow-up. Twenty patients are alive, with follow-up times from 2 to 38 years, median 13 years. Among the 28 children who survived the primary resection, eight underwent repeat surgery from 6 months to 5 years after the first operation. Two children were operated three times, and one of these also a fourth time. Gross total resection (GTR) was achieved in 20 of the primary resections, subtotal resection (STR) in 6, and in the last 4, only a biopsy or a partial resection was performed. Nine children received adjuvant chemotherapy and three of these also radiotherapy (in the years 1979-1987). Among the 20 survivors, the Barthel index is normal (100) in 18 patients, 40 in one, and 20 in the last one. Eight tumors were located to the posterior fossa, and 22 were supratentorial. Eighteen tumors were histologically low-grade (WHO grade I-II), most of these were plexus papillomas (7) or astrocytomas (7), and 12 were high-grade (WHO grade III-IV); PNET/medulloblastomas (6), ependymoma (2), glioblastoma (2), teratoma, and plexus carcinoma. CONCLUSION Infants with brain tumors may clearly benefit from surgical resection with favorable results even for prolonged periods of time. Ten children died, two of them with prolonged survival for 9 and 29 years. Among the 20 survivors, a stable very long-term result appears obtainable in 18 also when it comes to quality of life. Four of the survivors have been treated for highly malignant tumors with a follow-up of 5, 11, 14, and 26 years. One of our infant patients treated for GBM in 1982, lived for 29 years, however, with a progressive decline in the quality of life probably due to postoperative whole-brain radiation.

Abstract
OBJECTIVES An appraisal of pediatric cancer-specific quality-of-life (QOL) instruments revealed a lack of clarity about what constitutes QOL in this population. This study addresses this concern by identifying the concepts that underpin the construct of QOL as determined by a content analysis of all patient-reported outcome (PRO) instruments used in childhood cancer research. METHODS A systematic review was performed of key databases (i.e., MEDLINE, CINAHL, PsychINFO) to identify studies of QOL in children with cancer. A content analysis process was used to code and categorize all items from generic and cancer-specified PRO instruments. Our objective was to provide clarification regarding the conceptual underpinnings of these instruments, as well as to help inform the development of theory and contribute to building a conceptual framework of QOL for children with cancer. RESULTS A total of 6,013 English language articles were screened, identifying 148 studies. Ten generic and ten cancer-specific PRO instruments provided 957 items. Content analysis led to the identification of four major domains of QOL (physical, psychological, social, and general health), with 11 subdomains covering 98 different concepts. While all instruments reflected items relating to the broader domains of QOL, there was substantial heterogeneity in terms of the content and variability in the distribution of items. CONCLUSIONS This systematic review and the proposed model represent a useful starting point in the critical appraisal of the conceptual underpinnings of PRO instruments used in pediatric oncology and contribute to the need to place such tools under a critical, yet reflective and analytical lens.

Abstract
OBJECTIVE Health-related quality of life (HRQoL) has become an increasingly important measure of research and treatment outcomes across all medical specialties. However, to date, there has not been an in-depth review of research relevant specifically to HRQoL in the populations of children and adolescents with cancer. In this review, the authors examine the effects of cancer on HRQoL from diagnosis to remission/survivorship and the end of life. DESIGN A literature search was conducted using Medline and PsycINFO for articles published from 2002 to 2011. Studies included patients from diagnosis to remission and also the terminally ill. Twenty-nine studies specifically addressing HRQoL were selected after reaching consensus and study quality check. RESULTS Children who are newly diagnosed with cancer and are undergoing treatment or are terminally ill have impaired HRQoL. Survivors of childhood cancer have high HRQoL (with the exception of those who experienced medical comorbidity or PTSD). The authors found that demographic differences, cancer types, and treatment regimens, all significantly influence the negative impact of cancer on patients' HRQoL. CONCLUSIONS There are specific and identifiable impacts of childhood cancer on patients' HRQoL that are significant and complex across the span of the illness. There is a need for continued research in many areas related to this population, especially related to those with terminal illness in order to improve patient care.

Abstract
There is ample evidence that many children treated for brain tumors experience long-term neurocognitive deficits. The severity of those deficits is determined by a complex interaction of the child's genetic make-up and age, neuroanatomical damage caused by tumor and surgery, radiotherapy and chemotherapy, the psychosocial environment, and the intensity of targeted rehabilitation. The consequences of neurocognitive deficits are moderated by the number and severity of other deficits, including neurological and endocrine impairments, and this wider context must be considered. The impact of intellectual decline on academic functioning is evident, and underlies, for example, poor reading, writing, and mathematical skills. The effects of early brain damage on development are cumulative as more functions are expected to mature. Many survivors of CNS tumors can be expected to grow into deficits that have far-reaching consequences not only for academic achievement but also for their psychological and social development and their ability to be self-sufficient. Because the problems typically only become apparent over time, surveillance for their detection is an essential prerequisite for early educational and other interventions to support learning and successful transition to independent adult life.

Abstract
Poly ADP-ribose polymerase (PARP) is a protein involved in single strand break repair. Recently, PARP inhibitors have shown considerable promise in the treatment of several cancers, both in monotherapy and in combination with cytotoxic agents. Synthetic lethal action of PARP inhibitors has been observed in tumors with mutations in double strand break repair pathways. In addition, PARP inhibition potentially enhances sensitivity of tumor cells to DNA damaging agents, including radiotherapy. Aim of this study is to determine the radiosensitizing properties of the PARP inhibitor Olaparib in childhood medulloblastoma, ependymoma and high grade glioma (HGG). Increased PARP1 expression was observed in medulloblastoma, ependymoma and HGG, as compared to non-neoplastic brain tissue. Pediatric high grade glioma, medulloblastoma and ependymoma gene expression profiling revealed that high PARP1 expression is associated with poor prognosis. Cell growth inhibition assays with Olaparib resulted in differential sensitivity, with IC50 values ranging from 1.4 to 8.4 μM, irrespective of tumor type and PARP1 protein expression. Sensitization to radiation was observed in medulloblastoma, ependymoma and HGG cell lines with subcytotoxic concentrations of Olaparib, which coincided with persistence of double strand breaks. Combining PARP inhibitors with radiotherapy in clinical studies in childhood high grade brain tumors may improve therapeutic outcome.

Abstract
OBJECTIVE Intracranial tumors are rare in the first year of life. This study evaluates survival rates and functional outcomes of survivors at least 5 years after diagnosis and the predictors of this outcome. METHODS A retrospective chart review of all infants with a primary intracranial tumor was carried out. Radiology and pathology were re-reviewed. Outcome was assessed at 5 years or more after diagnosis using Bloom's categories (Bloom 1-2 = good outcome, the rest = poor outcome) and late effects severity scoring. Age, tumor location, size, extent of tumor resection, type of adjuvant therapy given, and WHO grade of tumor histology were evaluated as predictors of outcome. RESULTS Among 35 infants, 20 (57%) survived, with 12 (34%) having a good outcome. Deficits among the survivors included neurological dysfunction in 14 (70%), visual impairment in 9 (45%), endocrine dysfunction in 5 (25%), and auditory disability in 3 (15%). Ten of the 20 survivors were either attending regular school or were engaged in a skilled job. At presentation, older age and an infratentorial location of the tumor are predictors of poor outcome. After histopathological diagnosis, the WHO grading of tumor is the only independent predictor of survival (p = 0.002) and functional outcome (p < 0.001). CONCLUSION About a third of the infants diagnosed with brain tumors (34%) had a good functional outcome and approximately a quarter of them (28%) were able to attend regular school or take up a skilled job. After tissue diagnosis, histological grade of tumor is the only independent predictor associated with outcome.

Abstract
In addition to the usual developmental challenges, children and adolescents with chronic physical illness face psychosocial challenges that affect their quality of life. This review describes different aspects of coping with chronic physical illness in childhood and the empirical evidence examining the usefulness of cognitive-behavioral therapy (CBT) for the treatment of children and adolescents with chronic physical illnesses and related psychological comorbidities. Four diseases (diabetes, inflammatory bowel disease, cancer, and sickle cell disease) were chosen as model illnesses to demonstrate key CBT findings in more detail. Future research recommendations in this challenging population are also addressed.

Abstract
PURPOSE To evaluate the incidence of infant brain tumors and survival outcomes by disease and treatment variables. METHODS AND MATERIALS The Surveillance, Epidemiology, and End Results (SEER) Program November 2008 submission database provided age-adjusted incidence rates and individual case information for primary brain tumors diagnosed between 1973 and 2006 in infants less than 12 months of age. RESULTS Between 1973 and 1986, the incidence of infant brain tumors increased from 16 to 40 cases per million (CPM), and from 1986 to 2006, the annual incidence rate averaged 35 CPM. Leading histologies by annual incidence in CPM were gliomas (13.8), medulloblastoma and primitive neuroectodermal tumors (6.6), and ependymomas (3.6). The annual incidence was higher in whites than in blacks (35.0 vs. 21.3 CPM). Infants with low-grade gliomas had the highest observed survival, and those with atypical teratoid rhabdoid tumors (ATRTs) or primary rhabdoid tumors of the brain had the lowest. Between 1979 and 1993, the annual rate of cases treated with radiation within the first 4 months from diagnosis declined from 20.5 CPM to <2 CPM. For infants with medulloblastoma, desmoplastic histology and treatment with both surgery and upfront radiation were associated with improved survival, but on multivariate regression, only combined surgery and radiation remained associated with improved survival, with a hazard ratio for death of 0.17 compared with surgery alone (p = 0.005). For ATRTs, those treated with surgery and upfront radiation had a 12-month survival of 100% compared with 24.4% for those treated with surgery alone (p = 0.016). For ependymomas survival was higher in patients treated in more recent decades (p = 0.001). CONCLUSION The incidence of infant brain tumors has been stable since 1986. Survival outcomes varied markedly by histology. For infants with medulloblastoma and ATRTs, improved survival was observed in patients treated with both surgery and early radiation compared with those treated with surgery alone.

Abstract
Brain tumors in infants (under the age of 1 yr) are mercifully rare. Nonetheless, neonatal tumours present a treatment challenge to those involved. Surgery can be technically challenging, if possible at all, and the sensitivity of the developing nervous system to the side-effects of radio- and chemotherapy has limited their utility as adjunctive treatments. The risk/benefit equation in the planning of treatment of neonatal tumours using these modalities is further complicated by the fact that these tumours are often histologically benign, of large dimensions, but are often situated in locations that lead to a fatal outcome. This review article seeks to provide guidance on the management of neonatal patients and infants up to 1 year of age with brain tumours based on evidence from the literature.

Abstract
INTRODUCTION One seventh of pediatric brain tumors are diagnosed in the first year of life. With more widespread and accessible neuroimaging, these lesions are being diagnosed earlier, but there remains scant literature about their natural history. METHODS A retrospective review was performed of brain tumor patients presenting to the Children's Hospital of Eastern Ontario (CHEO) through the last 34 years. Patients presenting in the first year of life, including symptoms, management features, and functional outcome, were analyzed using ANOVA and chi (2) statistics. RESULTS Eighteen cases of brain tumors in the first year of life were identified: 12 suptratentorial, eight with benign histology, and six infratentorial all with malignant histology. Median age of presentation differed by lesion location (p = 0.05) and glial tumors were most common. Raised intracranial pressure was more than twice as prevalent with posterior fossa lesions (p < 0.01) with equivalent likelihood of increasing head circumference (p = 0.74), whereas seizures were more frequent with supratentorial tumors (p = 0.04). Gross total resection was achieved in 47% of patients, cerebrospinal fluid diversion was more frequently necessary among infratentorial lesions (p = 0.02), and adjuvant therapy was more utilized for infratentorial lesions (p < 0.01). Among eight surviving infants, seven had supratentorial tumors, five survived to adulthood, and six are functionally independent. CONCLUSIONS Brain tumors in the first year of life represent 4.8% of patients treated at CHEO. Mode of presentation, utilization of adjuvant therapy, and survival depend on tumor location and histology, with worse prognosis for infratentorial lesions. One third of patients had acceptable functional outcome requiring no special assistance.

Abstract
Acquired brain injury (ABI) in children and adolescents can result from multiple causes, including trauma, central nervous system infections, noninfectious disorders (epilepsy, hypoxia/ischemia, genetic/metabolic disorders), tumors, and vascular abnormalities. Prediction of outcomes is important, to target interventions, allocate resources, provide education to family or caregivers, and begin appropriate planning for the future. Researchers have identified several factors associated with better or worse outcomes after ABI, including variables related to the injury itself, postinjury factors related to intervention or trajectory of recovery, and preinjury or demographic factors. When examining the scientific literature, it is important to identify how "outcome" is defined, as the predictors may change depending on the outcome studied. In addition, key variables may be specific to the etiology of injury. Therefore, predictors of outcome cannot be generalized across the various etiologies of ABI, and this review will discuss predictors within the context of multiple etiologies of ABI. This article reviews the current literature on predicting outcomes after pediatric ABI, and areas in need of further research are discussed.

Abstract
OBJECTS To study the long-term outcome of surgically treated low-grade cerebellar astrocytomas in children. MATERIALS AND METHODS We followed 31 consecutive patients under 16 years of age who were diagnosed between 1980 and 2005 in a single institution. In 21 of 31 survivors (median follow-up time 7.9 years; range 5.6-27.4 years) who agreed to participate, tumor control, neurological and cognitive complications, and their impact on behavioral and emotional adjustment and health-related quality of life (HRQoL) were comprehensively assessed qualitatively and quantitatively. RESULTS Neurological sequelae were found in 43%. However, age-appropriate ability to perform daily life activities was normal in all patients. Remarkably, cognitive deficits leading to significant school problems occurred in 19% and behavioral and emotional adjustment disturbances in 27%. In comparison with healthy controls, the survivors rated their HRQoL similarly or even higher. CONCLUSION Childhood low-grade cerebellar astrocytomas have an excellent cure rate by tumor surgery alone. When compared with other pediatric brain tumors, the risk of neurological, cognitive, emotional, and behavioral complications is relatively small. HRQoL is similar to that of healthy controls.
