Abstract
PURPOSE To examine two competing hypotheses relating to intellectual loss among children treated for medulloblastoma (MB): Children with MB either: (1) lose previously learned skills and information; or (2) acquire new skills and information but at a rate slower than expected compared with healthy same-age peers. PATIENTS AND METHODS Forty-four pediatric MB patients were evaluated who were treated with postoperative radiation therapy (XRT) with or without chemotherapy. After completion of XRT, a total of 150 examinations were conducted by use of the child version of the Wechsler Intelligence SCALES: These evaluations provided a measure of intellectual functioning called the estimated full-scale intelligence quotient (FSIQ). Changes in patient performance corrected for age (scaled scores) as well as the uncorrected performance (raw scores) were analyzed. RESULTS At the time of the most recent examination, the obtained mean estimated FSIQ of 83.57 was more than one SD below expected population norms. A significant decline in cognitive performance during the time since XRT was demonstrated, with a mean loss of 2.55 estimated FSIQ points per year (P =.0001). An analysis for the basis of the intelligence quotient (IQ) loss revealed that subtest raw score values increased significantly over time since XRT, but the rate of increase was less than normally expected, which resulted in decreased IQ scores. CONCLUSION These results support the hypothesis that MB patients demonstrate a decline in IQ values because of an inability to acquire new skills and information at a rate comparable to their healthy same-age peers, as opposed to a loss of previously acquired information and skills.

Abstract
PURPOSE To test if methylphenidate (MPH) has an objective beneficial effect on immediate performance on tests of neurocognitive functions among learning-impaired survivors of childhood acute lymphoblastic leukemia (ALL) and malignant brain tumors (BT). PATIENTS AND METHODS From July 1, 1997 through December 31, 1998, 104 long-term survivors of childhood ALL or a malignant BT completed neurocognitive screening for learning impairments and concurrent problems with sustained attention. Eligibility criteria for the MPH trial included an estimated intelligence quotient greater than 50, academic achievement in the 16(th) percentile or lower for age in reading, math, or spelling, and an ability to sustain attention on a computerized version of the Conners' Continuous Performance Test (CPT) in the 16(th) percentile or lower for age and sex. Of the 104, 32 (BT, n = 25; ALL, n = 7) were eligible on the basis of these a priori criteria for a randomized, double-blinded, placebo-controlled trial of MPH. The patients ingested a placebo (lactose) or MPH (0.6 mg/kg; 20 mg maximum) and repeated selected portions of the screening battery 90 minutes later. RESULTS Compared to the 17 patients randomized to the placebo group, the 15 patients randomized to the MPH group had a significantly greater improvement on the CPT for sustained attention (errors of omission, P =.015) and overall index (P =.008) but not for errors of commission (indicative of impulsiveness) nor reaction times. A trend for greater improvement in the MPH group on a measure of verbal memory failed to reach statistical significance. No trend was observed for MPH effectiveness in improving learning of a word association task. No significant side effects from MPH were observed. CONCLUSION MPH resulted in a statistically significant improvement on measures of attention abilities that cannot be explained by placebo or practice effects.

Abstract
PURPOSE To test the hypothesis that inadequate development of normal-appearing white matter (NAWM) is associated with the relationship between young age at the time of craniospinal irradiation (CRT) and deficient neurocognitive performance in survivors of childhood medulloblastoma. PATIENTS AND METHODS Forty-two patients treated since 1985 participated in this cross-sectional study. All had been treated with CRT with or without chemotherapy and had survived 1 or more years after treatment. Neurocognitive evaluations were conducted with tests of intellect (intelligent quotient; IQ), verbal memory, and sustained attention. Quantitative magnetic resonance imaging, using a hybrid neural network, assessed the volume of NAWM. RESULTS Neurocognitive test results were below normal expectations for age at the time of testing. A young age at CRT was significantly associated with worse performance on all neurocognitive tests except that of verbal memory. An increased time from completion of CRT was significantly associated with worse performance on all neurocognitive tests except that of sustained attention. After statistically controlling for the effects of time from CRT, we examined the association of NAWM with neurocognitive test results. These analyses revealed that NAWM accounted for a significant amount of the association between age at CRT and IQ, factual knowledge, and verbal and nonverbal thinking, but not sustained attention or verbal memory. CONCLUSION The present results suggest that, at least for some cognitive functions, deficient development and/or loss of NAWM after CRT may provide a neuroanatomical substrate for the adverse impact of a young age at the time of CRT.

Abstract
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.

Abstract
Medulloblastoma is the most common malignant brain tumor in children, and approximately seventy percent of average-risk patients will achieve long-term survival. Craniospinal irradiation (CSI), combined with chemotherapy and surgery, is currently the mainstay of treatment but places children who survive at risk for serious neurocognitive sequelae. These sequelae are intensified with a younger age at treatment, greater elapsed time following treatment, and an increased radiation dose. Many newer treatment approaches have attempted to address this problem by reducing the dose of the CSI component of radiation therapy while maintaining the current survival rates. This study evaluates longitudinal MR imaging during therapy to assess the impact of the two CSI doses (conventional [36 Gy] and reduced [23.4 Gy]) on normal appearing white matter volumes (NAWMV) evaluated in a single index slice. Twenty-six children and young adults at least three years of age enrolled on an institutional protocol for newly diagnosed, previously untreated primary medulloblastoma had at least four MR examinations over a minimum nine month period following CSI. These serial volumes were evaluated as a function of time since CSI in three analyses: 1) all subjects, 2) subjects stratified by age at CSI, and 3) subjects stratified by CSI dose. The first analysis demonstrated that medulloblastoma patients treated with CSI have a significant loss of NAWMV in contradistiction to normally expected maturation. Stratifying the patients by age at CSI found no significant differences in the rate of NAWMV loss. The final analysis stratified the patients by CSI dose and revealed that the rate of NAWMV loss was 23% slower in children receiving reduced-dose. Serial quantitative MR measures of NAWMV may provide a neuroanatomical substrate for assessing functional impact of CSI on normal brain function following treatment for medulloblastoma.

Abstract
This is the eighth official document of the SIOP Working Committee on Psychosocial Issues in Pediatric Oncology, instituted in 1991. It deals with a topic discussed and approved by the SIOP Committee; namely, "Recognition, prevention, and remediation of burnout in health care professionals participating in the care of children with cancer." It is addressed to the Pediatric Oncology community and outlines: 1) the general definition of burnout as mental and physical exhaustion, indifference, sense of failure as a professional, and sense of failure as a person; 2) the causes of burnout from the nature of the work itself, the work environment, and the characteristics of the individual; 3) the prevention of burnout, changing the detrimental aspects of one's work environment and modifying one's own behavior; and accepting methods to remediate burnout when it occurs.

Abstract
Children surviving medulloblastoma have a high risk for chronic, treatment-related neurocognitive deficits. Neuropsychological testing provides important data regarding the comparative toxicities of various therapeutic approaches. However, such testing can be expensive and logistically difficult, especially if a consulting psychologist is not readily available at the treating institution. Our purpose was to investigate the usefulness of a health-related quality of life inventory that does not require a psychologist for completion. We assessed the concurrent validity of traditional intelligence (IQ) testing and levels on the Cognition attribute of the multi-attribute Health Utilities Index Mark 2 (HUI 2) in estimating academic achievement scores of 22 patients treated for medulloblastoma with craniospinal irradiation following surgical resection. The results demonstrated that the Cognition utility scores were significantly lower than scores from the other components of the HUI 2 (Sensation, Mobility, Emotion, Self-Care, Pain). Cognition scores were also significantly positively correlated with IQ and achievement scores. Furthermore, Cognition scores were significantly lower among children who had received special educational services when compared with those who had not received such services. Our results provide preliminary evidence of the potential usefulness of the HUI 2 Cognition attribute in estimating IQ, achievement and the likelihood of the need for special educational services among children treated for medulloblastoma.

Abstract
We have examined the influence of selected factors (gender, marital status, socio-economic status, co-morbid conditions, access to medical care, age at diagnosis, intensity of therapy and time since diagnosis) on subsequent health status and health-related quality of life (HRQL) of long-term survivors of pediatric solid tumors. Two hundred and twenty individuals who had survived a pediatric solid tumor 15 years or longer completed telephone and written assessments of their current status. Health status was assessed using the Late Effects of Normal Tissues toxicity scale. HRQL was investigated using the Ferrans and Powers Quality of Life Index-Cancer (QLIC) and the EORTC Quality of Life Questionnaire C30 (QLQ-C30). Results indicated that health status and HRQL were better in survivors treated with low-intensity therapy. One hundred and thirty respondents (59.1%) reported at least 1 serious toxicity. Dyspnea and fatigue were commonly reported in survivors of Hodgkin's disease. Correlational analyses showed that predictors of health status included socio-economic status, marital status and the presence of co-morbid factors. Mean HRQL scores for the 4 domains of the Ferrans and Powers QLIC and the functional scales of the EORTC QLQ-C30 indicated that most of the survivors were experiencing moderately good to excellent HRQL. One-third of survivors reported that their history of cancer had an adverse impact on their current financial status. Prediction models constructed for 3 of the domains from the 2 HRQL instruments are presented (health and functioning, global HRQL and financial impact). Within these 3 models, consistent predictors of HRQL outcomes included health status, presence of dyspnea or pain, marital status and socio-economic status.

Abstract
PURPOSE To provide evidence that radiation therapy alone in the form of craniospinal irradiation (CSI) and a boost to the primary site of disease provides effective disease control and limited additional morbidity for patients with CNS germinoma. METHODS AND MATERIALS Twelve patients with a median age of 12 years (range 9-16 years) with CNS germinoma were treated with CSI (median 25.6 Gy, range 23.4-32 Gy) and a boost to the primary site of disease (50.4 Gy, range 45-54 Gy) between January 1987 and June 1998. All patients were biopsied prior to radiation therapy and none received chemotherapy. No patients were lost to follow-up and the majority had long-term (> 45 month) pre- and postirradiation endocrine and psychology assessment. RESULTS All 12 patients are alive and no failures have occurred with a median follow-up of 69 months (range 14-143 months). Preirradiation endocrine deficiencies were present in 6 of 6 suprasellar tumors and 1 of 6 pineal tumors; with follow-up there was no substantial difference between age and gender adjusted pre- and postirradiation stature and weight. With long-term follow-up, there were no significant differences between pre- and postirradiation full-scale, verbal, and performance IQ scores. CONCLUSIONS This study confirms the ability of radiation therapy alone to achieve disease control with a high rate of success in pediatric patients and demonstrates that the treatment toxicity faced by these patients may be less than anticipated. Because these patients present with substantial preexisting morbidity at diagnosis and may be of an age where the potential for radiation-related side effects is relatively small, the superiority of treatment alternatives may be difficult to prove.

Abstract
PURPOSE To evaluate cognitive and academic functioning in survivors of pediatric bone marrow transplants (BMTs) at 1 and 3 years after a BMT. PATIENTS AND METHODS In a prospective, longitudinal design, patients underwent a comprehensive battery of neurocognitive measures before admission for transplantation and at 1, 3, and 5 years after a BMT. This article describes a cohort of 102 survivors with follow-up data available for 1 year after a BMT, including 54 survivors with follow-up available for 3 years. This represents the largest cohort of pediatric BMT survivors yet reported in a prospective study. RESULTS In the cohort as a whole, there were no significant changes on global measures of intelligence (intelligence quotient [IQ]) and academic achievement at either 1 or 3 years after a BMT, despite adequate power to detect an IQ change of three points or greater. Likewise, performance on specific tests of neuropsychologic function remained stable. No significant differences were observed between patients whose conditioning regimen included total-body irradiation (TBI) and those whose did not. The primary predictor of neurocognitive outcome was patient age, with younger patients more likely to show declines over time. The subset of patients who were less than 3 years of age at the time of transplantation seemed to be particularly vulnerable to cognitive sequelae. CONCLUSION The use of BMTs with or without TBI entails minimal risk of late neurocognitive sequelae in patients who are 6 years of age or older at the time of transplantation. However, patients who are less than 6 years of age at the time of transplantation, and particularly those less than 3 years of age, seem to be at some risk of cognitive declines.

Abstract
PURPOSE Young children treated for medulloblastoma are at especially high risk for morbidity and mortality from their disease and therapy. This study sought to assess the relationship, if any, between patient outcome and M stage. Neuropsychologic and endocrine outcomes were also assessed. PATIENTS AND METHODS Twenty-nine consecutively diagnosed infants and young children were treated for medulloblastoma at St Jude Children's Research Hospital between November 1984 and December 1995. All patients were treated with the intent of using postoperative chemotherapy to delay planned irradiation. RESULTS The median age at diagnosis was 2.6 years. Six patients completed planned chemotherapy without progressive disease and underwent irradiation at completion of chemotherapy. Twenty-three children experienced disease progression during chemotherapy and underwent irradiation at the time of progression. The 5-year overall survival rate for the entire cohort was 51% +/- 10%. The 5-year progression-free survival rate was 21% +/- 8%. M stage did not impact survival. All patients lost cognitive function during and after therapy at a rate of -3.9 intelligence quotient points per year (P =.0028). Sensory functions declined significantly after therapy (P =.007). All long-term survivors required hormone replacement therapy and had growth abnormalities. CONCLUSION The majority of infants treated for medulloblastoma experienced disease progression during initial chemotherapy. However, more than half of these patients can be cured with salvage radiation therapy, regardless of M stage. The presence of metastatic disease did not increase the risk of dying from medulloblastoma. All patients treated in this fashion have significant neuropsychologic deficits. Our experience demonstrates that medulloblastoma in infancy is a curable disease, albeit at a significant cost.

Abstract
Although previous studies have documented a significant risk of intellectual loss after treatment for childhood medulloblastoma (MED), the pathophysiology underlying this process is poorly understood. The purpose of this study was to test the hypotheses that (1) patients treated for MED in childhood have reduced volumes of normal white matter (NWM) related to their treatment with craniospinal irradiation with or without chemotherapy, and (2) deficits in NWM among patients surviving MED can at least partially explain deficits in their intellectual performance. Eighteen pediatric patients previously treated for MED were matched on the basis of age at the time of evaluation to 18 patients previously treated for low-grade posterior fossa tumors with surgery alone (mean difference, 3.7 months). Evaluations were conducted with age-appropriate neurocognitive testing and quantitative magnetic resonance imaging by using a novel automated segmentation and classification algorithm constructed from a hybrid neural network. Patients treated for MED had significantly less NWM (p < 0.01) and significantly lower Full-Scale IQ values than those treated for low-grade tumors (mean, 82.1 vs 92.9). In addition, NWM had a positive and statistically significant association with Full-Scale IQ among the patients treated for MED. We conclude that irradiation- or chemotherapy-induced destruction of NWM can at least partially explain intellectual and academic achievement deficits among MED survivors.

Abstract
Our objective was to test a hypothesis that subtle brain abnormality can be present in pediatric sickle cell disease (SCD) patients who are clinically free of stroke. We prospectively compared 50 patients with 52 healthy age-similar controls, using quantitative magnetic resonance imaging. A previously validated precise and accurate inversion-recovery method was used to measure T1 in a slice at the basal ganglia. We also used the Wechsler test to measure intelligence quotient (IQ) in a randomly selected subset of 27 patients. Brain T1 was significantly lower in patients in every gray matter structure evaluated but in none of the white matter structures. Regression suggests that T1 in caudate, nucleus pulvinares, and cerebral cortex was abnormal by age 4 years. Psychometric testing showed that 33% of patients were functioning in the range of mild mental deficiency (IQ, 50-70), compared with a published prevalence of 1.45% in inner-city black children. Thus, in our patients, SCD was associated with a 23-fold increase in the risk of mild mental deficiency. Full-scale IQ of SCD patients was a function of hematocrit (Hct), and when Hct was used to stratify patients, those with an Hct of less than 27% had significantly lower psychometric test scores, and significantly lower gray matter T1, than those with an Hct of 27 or more. Both cognitive deficits and subtle T1 abnormalities were associated with a low Hct, and both could be present when conventional magnetic resonance imaging findings were normal. Our findings suggest that chronic hypoxia of brain tissue can occur in SCD patients free of clinical stroke.

Abstract
This, the sixth official document of the SIOP Working Committee on psychosocial issues in pediatric oncology, develops another important and especially difficult topic: assistance for terminally ill children with cancer. This is provided for the pediatric oncology community as a useful set of guidelines. It should be always possible for a declining child to die without unnecessary physical pain, fear, or anxiety. It is essential that he or she receive adequate medical, spiritual, and psychological support, and that the child at no point feels abandoned. Palliative care, in the terminal phase of cancer, should be tailored to the different needs and desires of the child and the family, with the goal of providing the best possible quality of life for the days that remain.

Abstract
OBJECTIVE To determine whether abnormalities of the CNS are present in very young children with sickle cell anemia. STUDY DESIGN Thirty-nine children with hemoglobin SS between the ages of 7 and 48 months were examined with magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). No child had a history of clinical stroke, although 3 had a history of seizures (2 neonatal). Twenty-one patients underwent developmental testing with the Bayley or McCarthy Scales. RESULTS The overall prevalence of CNS abnormalities in asymptomatic children was 4 of 36 (11%, confidence interval 3, 26%). One patient had a silent infarct observed on MRI and a stenotic lesion on MRA; 3 other patients had stenotic lesions on MRA. The 3 patients who had a history of seizures all had lesions consistent with infarcts on MRI. Of the asymptomatic patients who had psychometric testing, 1 of 18 was developmentally delayed. One of 3 with a history of seizures had mild developmental delay. CONCLUSIONS Very young children with sickle cell anemia (and no history of clinical stroke) have infarction in the brain and/or stenosis of major cerebral arteries, similar to those reported in older children. These findings indicate a need for larger studies to define the incidence of CNS lesions in this age group and to determine the need for early therapeutic intervention to prevent CNS sequelae of sickle cell disease.

Abstract
PURPOSE The purpose of this study was to test the hypothesis that survivors of medulloblastoma who were younger at diagnosis and those who received standard-dose cranial irradiation (SRT) of 36 Gy would have a lower performance on standardized tests of cognitive function and achievement than children who were older and those treated with reduced-dose cranial irradiation (RRT) of 23.4 Gy. PATIENTS AND METHODS Eligible patients had been treated on Pediatric Oncology Group (POG) study 8631 for low-risk medulloblastoma that randomized patients to receive RRT or SRT after surgical resection. Those who were alive and free of progressive disease 6.1 to 9.9 years from completion of treatment were eligible for this study. Of the 35 eligible patients, 22 patients (13 SRT, nine RRT) participated in a battery of tests that included intellectual and academic development as well as ratings of health-related quality of life. RESULTS Patients were stratified by treatment group (SRT v RRT) and into younger (Y) and older (O) groups by the median age at diagnosis (8.85 years), which resulted in four groups that we hypothesized would show neuropsychologic test scores in the following order: Y/SRT less than Y/RRT less than O/SRT less than O/RRT. Evidence to support the hypothesized ordering of groups in terms of neuropsychologic toxicity was obtained with regard to Performance Intelligence Quotient (IQ), Full Scale IQ, Attention, Reading, and Arithmetic. CONCLUSION Children treated for medulloblastoma experienced less severe neuropsychologic toxicity when treated with 23.4 Gy instead of 36 Gy cranial irradiation. Older children experienced less toxicity than children who were younger at the time of irradiation.

Abstract
Conventional MRI (cMRI) has shown that brain abnormalities without clinical stroke can manifest in patients with sickle cell disease (SCD). We used quantitative MRI (qMRI) and psychometric testing to determine whether brain abnormalities can also be present in patients with SCD who appear normal on cMRI. Patients 4 years of age and older with no clinical evidence of stroke were stratified by cMRI as normal (n = 17) or abnormal (n = 13). Spin-lattice relaxation time (T1) of gray and white matter structures was measured by the precise and accurate inversion recovery (PAIR) qMRI method. Patient cognitive ability was assessed with a standard psychometric instrument (WISC-III or WISC-R). In all 30 patients with SCD, qMRI T1 was lower than in 24 age- and race-matched controls, in cortical gray matter (P < .0006) and caudate (P < .0009), as well as in the ratio of gray-to-white matter T1 (P < .008). In the 17 patients who were shown to be normal by cMRI, qMRI T1 was still lower than in controls, in both cortical gray matter (P < .02) and caudate (P < .004). Histograms of voxel T1 show that the proportion of voxels with T1 values intermediate between gray and white matter (ie, consistent with encephalomalacia) was 9% higher than controls in patients shown to be normal by cMRI (P < .05) and 15% higher than controls in patients shown to be abnormal by cMRI (P < .0005). The full scale intelligence quotient (FSIQ) of all patients with SCD was 75, compared to the FSIQ of 88 in a historical control group of patient siblings (P < .001). The FSIQ of patients shown to be normal by cMRI was 79, significantly lower than the FSIQ of patient siblings (P < .04). The FSIQ of 71 in patients shown to be abnormal by cMRI was significantly lower than both the patient siblings (P < .005) and the patients shown to be normal by cMRI (P < .04). Patients shown to be abnormal by cMRI scored lower than patients shown to be normal by cMRI, specifically on the subtests of vocabulary (P = .003) and information (P = .03). Cognitive impairment is thus significant, even in patients with SCD who were shown to be normal by cMRI, suggesting that cMRI may be insensitive to subtle neurologic damage that can be detected by qMRI. Because cognitive impairment can occur in children normal by cMRI, our findings imply that prophylactic therapy may be needed earlier in the course of SCD to mitigate neurologic damage.

Abstract
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.

Abstract
Outcomes from 42 studies of psychological interventions for children and adolescents with chronic medical conditions were analyzed using meta-analysis. Studies were divided into the four intervention categories suggested by LaGreca and Varni (1993), Disease Management, Emotional/Behavioral Problems, Health Promotion, and Prevention. Results supported overall effectiveness of psychological interventions, with an effect size (ES) of 1.12, as well as maintenance of treatment gains for at least 12 months posttreatment. Psychological interventions directed at disease-related or emotional/behavioral problems were both found to be effective, although too few studies of health promotion or disease prevention interventions were identified to be included in the analysis. Effectiveness of behavioral interventions, which were most heavily represented in the sample, demonstrated similar effects for disease management (ES = 1.20) and emotional/behavioral (ES = 1.03) problems. Although disease type, severity, and duration did not affect intervention effectiveness, some influences of patient age and gender were noted across studies. Recommendations for further intervention studies and improvements in study design are discussed.

Abstract
GOAL To determine whether children with sickle cell disease (SCD), but without clinical evidence of cerebrovascular disease, have vasculopathy shown by quantitative magnetic resonance angiography (MRA). METHODS In a retrospective review of MRA films, we compared 47 SCD patients with 49 control patients. Time-of-flight three-dimensional T1-weighted gradient-echo images were reconstructed, by maximum-intensity projection, to show the basilar artery in coronal view, and basilar volume was calculated from measurements made on films. Basilar volume was correlated with hematocrit and with results of cognitive testing. FINDINGS Mean basilar artery volume was 74% larger in SCD patients than in controls (P<.001). If the upper limit of normal is defined as mean adult volume +2 SD (< or =427 mm(3)), 2% (1 of 43) of controls but 37% (17 of 46) of SCD patients exceed this value (chi(2)=19.0; P<.001). Basilar volume correlated inversely with hematocrit (r=-.60; P<.0001), with full-scale IQ (r=-.62; P<.005), and with freedom from distractability (r=-.61; P<.006) in SCD patients. Analysis of basilar artery tissue from a 5-year-old SCD patient showed that basilar dilatation can be associated with pathological changes typical of hypertension. CONCLUSIONS Approximately 37% of a heterogenous group of pediatric SCD patients had ectasia of the basilar artery. Quantitative MRA is sensitive to subtle vasculopathy that can go undetected in the qualitative analysis more commonly done. Data suggest that there is a substantial elevation of arteriolar blood volume in pediatric SCD patients, and that such patients may share disease features in common with adult hypertension.

Abstract
OBJECTIVE To assess the psychological functioning of adolescent and young adult survivors of pediatric malignancy, and identify risk factors for maladjustment. DESIGN Patients age > or = 14.5 years (N = 161) receiving surveillance follow-up at a major pediatric cancer center completed the SCL-90-R, a self-report measure of psychological symptomatology. Comparisons were made with the normative standardization sample, and the relationship of selected demographic and medical variables with psychological distress was explored using logistic regression analyses. RESULTS Survivors mean scores on all SCL-90-R subscales were lower than those of the standardization sample, and the distribution of scores on the Anxiety, Psychoticism, Global severity Index, and Positive Symptom Total scales were significantly below normative values. No SCL-90-R subscale displayed an excessive frequency of clinically elevated scores. For patients who displayed clinical elevations on the SCL-90-R, three factors were identified which were associated with increased risk of maladjustment; older patient age at follow-up, more frequent disease relapse, and more severe functional impairment. CONCLUSIONS This cohort of childhood cancer survivors is characterized by very low levels of psychological distress and significantly better psychological health than would be expected according to normative data. These findings contrast with those of another study from the same institution in which a fourfold increase in social and behavioral problems was found amongst younger survivors, in the age range 7-15. The use of self-report vs. parent-report, and the potential influence of repressive adaptation on the self-reports of pediatric cancer survivors, are raised as possible explanations for these findings.

Abstract
This multi-institutional study investigated the association of behavioral/emotional adaptation among siblings of children with cancer with maternal general well-being, physical health, and resource use. One hundred seventy siblings and mothers completed standardized interviews and self-report measures 6 to 42 months after the cancer was diagnosed. As a group, mothers of children with cancer reported significantly lower levels of well-being than matched controls. When stratified according to the level of the sibling's behavioral/emotional adaptation, mothers of siblings in the Dysfunctional group (1) reported the lowest levels of well-being; (2) during the preceding year, were more likely to have sought professional services than mothers of children in the Resilient group; and (3) were least likely to have found social support helpful. Our results support an association between maternal well-being and sibling adjustment but show it is unlikely that nonspecific social support will improve adjustment. The rationale for problem-solving training for mothers is provided.

Abstract
Investigated the prevalence of anticipatory nausea and vomiting (ANV) among 59 pediatric cancer patients who had routinely received ondansetron (Zofran) antiemetic therapy and determined patient- and treatment-related factors associated with ANV. Of the sample, 59% indicated at least mild ANV symptoms, suggesting that a significant number of patients report ANV and are bothered by it, despite the use of Zofran. These children were compared to those reporting no ANV symptoms. Most ANV symptomatology was consistent with a traditional classical conditioning model although cognitive processes may also play a role. Children with greater expectations of severe postchemotherapy vomiting and those who were more distressed by nausea and vomiting were more likely to experience ANV symptoms. Implications for psychological and pharmacological treatments of ANV are discussed.

Abstract
We examined the influence of cognitive factors and conditioning variables on anticipatory nausea and vomiting symptoms (ANV) in 32 pediatric cancer patients with postchemotherapy nausea and vomiting (PNV) who received ondansetron. The patients were compared with 18 patients without ANV (NANV). Age, gender, history of motion sickness, aggressiveness of the chemotherapy, PNV severity, number of chemotherapy treatments, number, type, and efficacy of self-reported coping strategies, and expectations of severity of postchemotherapy symptoms failed to differentiate the ANV and NANV groups. The amount of subjective distress associated with nausea and vomiting was significantly greater in the ANV group. Among patients in whom ANV developed, level of distress and expectations of severity of postchemotherapy symptoms were positively correlated with the severity of ANV and PNV symptoms. Therefore, greater distress might increase the likelihood of ANV conditioning. Once ANV is conditioned, cognitive factors might influence the severity of symptoms.

Abstract
OBJECTIVE This seven-site study examined the overall health status, healthcare utilization, somatization, and health-risk behaviors of siblings of children with cancer compared to these factors in matched controls or normative data. The study also examined whether informants (i.e., siblings, parents, physicians) differed in their assessments of the above health domains. DESIGN Subjects were 254 siblings of children with cancer from seven different pediatric oncology treatment centers that participated in the Sibling Adaptation to Childhood Cancer Collaborative study group. Predictors of the siblings' health status, healthcare utilization, somatization, and health-risk behaviors were identified, and the relationship between these health domains and the siblings' resiliency vs. dysfunctionality were explored via interviews. RESULTS Overall, siblings were found to be moderately healthy, although siblings report significant problems with sleeping and eating. Healthcare utilization appears to be reduced for siblings. Most importantly, the parents of these siblings are less likely to seek medical help for a variety of conditions for which parents of control children would bring their children to a doctor. A pattern emerged of parental underreporting of sibling health variables when compared to what the siblings themselves reported. When the relationship between health outcomes and the siblings' adaptation to their sick sibling's illness was examined, the resilient and dysfunctional groups significantly differed from each other. It appears that health outcomes are related to sibling adaptation to the changes brought about by their sick sibling's cancer diagnosis and treatment. CONCLUSIONS The focus of care for families of children with cancer is often limited to the child with cancer. As indicated in this study, the "healthy" siblings may be overlooked in the process. While parents appear to recognize that their "healthy" children are complaining more about aches and pains, they may have little energy or time to attend to the needs of these other family members. It is the intent of this study to document what clinicians may expect and to highlight the need for evaluation of this otherwise neglected group.

Abstract
Nutritional problems often result from malignancies and aggressive multimodal treatment. Early identification of reliable risk factors associated with malnutrition and need for nutritional support is necessary for development of preventative approaches. Nutritional and treatment-related characteristics were examined for 173 pediatric oncology patients referred for nutritional support and a comparison sample of 43 patients matched on treatment protocol and/or diagnosis who had never been referred for nutritional support. Abnormally low serum albumin levels, poor oral intake, mucositis, prior radiation therapy, and increased gastrointestinal toxicity were significantly more frequent among referred than non-referred patients. A discriminant function analysis indicated that poor oral intake was the single best predictor of need for nutritional support. Patients with solid tumors were more nutritionally depleted at the time of referral; all bone marrow transplant patients received nutritional support. Patients with central nervous system (CNS) tumors required nutritional support for longer time periods. We conclude that routine documentation of poor oral intake (i.e., observation of change in a child's eating patterns) is the most reliable indicator of children who eventually require nutritional support and who may benefit from interventions that could delay or prevent nutritional problems. Prophylactic interventions should be tailored to meet the specific needs of individual diagnostic groups.

Abstract
The health-related beliefs and behaviors of long-term survivors of childhood cancer are important because of vulnerability to adverse late effects from their primary malignancy and its therapy. A health behavior survey was completed by 110 parents of long-term survivors ranging in age from 11-17 years, and by 40 adult long-term survivors of childhood cancer ranging in age from 18-29 years. The survey included questions on the former patient's frequency of alcohol and tobacco use, as well as diet, exercise, sleep, dental, and seatbelt habits. The reported prevalence of tobacco and alcohol use was less than 10% among those less than 18 years old. Among the adults, tobacco (17.5%) and alcohol (72.5%) use was greater, but problem drinking was infrequently reported. In order to assess their perceived vulnerability, we asked the parents and the young adult patients to rate the strength of their belief that it is more important for the patient to keep healthy compared to most other children or young adults. Contrary to our expectation, demographic factors such as the patient's gender, socioeconomic level, or time elapsed since completion of therapy exerted minimal influence on their responses. Over 80% of parents and 60% of young adult survivors believed that it was more important for the former patient to remain healthy compared to most other people. However, this shared belief in increased vulnerability was inconsistently expressed in the patient's health behaviors. These results suggest that specific changes are needed in the health assessment and education of long-term survivors of childhood cancer.

Abstract
The effect of perceived family environment as a determinant of adjustment in children undergoing bone marrow transplant (BMT) was assessed in a prospective, longitudinal study. Measures of patients' social competence, behavior problems, and self-esteem, along with perceived family conflict, cohesion, and expressiveness, were obtained before hospital admission for BMT and again in the period 6 to 12 months post-BMT. Significant declines were observed in post-BMT social competence and overall self-concept. Before BMT, perceptions of family conflict showed a moderate inverse correlation with patient adjustment, whereas family cohesion and expressiveness were unrelated or were weakly related with adjustment measures. In contrast, all pre-BMT family environment variables were highly predictive of adjustment post-BMT. Using a cross-lagged correlational approach, it was determined that perceived family cohesion and expressiveness act as protective factors, promoting resilience to the stresses of BMT, whereas family conflict acts directly as a risk factor that adversely affects adjustment regardless of stress level.

Abstract
We investigated the preference and perceived efficacy of coping strategies used to manage chemotherapy-induced nausea and emesis in 57 pediatric oncology patients. Over 85% of children preferred "Wishful Thinking," "Emotional Regulation," and "Distraction" to cope with nausea, and "Emotional Regulation" to manage emesis. Stepwise logistic regression analyses revealed that the coping strategy used and its perceived efficacy depended upon patient age and gender, severity of symptom distress, time elapsed from last chemotherapy, experience, and whether nausea or emesis was the identified problem. Successful copers, defined as those reporting high coping efficacy and minimal distress, composed only 25% of the sample. These children most often used "Problem Solving" combined with "Social Support" for symptom management. Successful coping was also associated with lower emetogenic potential of chemotherapy. The significance of these results is discussed for identifying high-risk children who may benefit from coping interventions.

Abstract
We investigated the epidemiology of pediatric anxiety and distress associated with magnetic resonance imaging procedures (MRIPs). Scores on the State-Trait Anxiety Inventory (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) and the State-Trait Anxiety Inventory for Children (Spielberger, Edwards, Lushene, Montuori, & Platzek, 1973), and subjective ratings of distress associated with MRIP were obtained from 55 pediatric oncology patients and their parents. Approximately 30% of children and their parents reported that MRIP produced significant distress. However, parents' ratings of their child's distress were significantly higher than children's self-ratings, and agreement between child and parent pairs was poor. Insertion of an intravenous line was identified as the most aversive component of MRIP by both parents (55%) and children (38%). The selective application of cognitive-behavioral interventions for noninvasive diagnostic procedures is suggested.

Abstract
Compared coping styles in children with cancer (n = 66) and a normative control group of healthy children (n = 414), using a newly designed instrument, the Children's Behavioral Style Scale (CBSS). We hypothesized that children in the oncology group would make greater use of an avoidant coping style (blunting) than controls. Results confirmed the primary hypothesis; children with cancer endorsed greater use of blunting or avoidant coping than did healthy children. A new conceptual model of coping style was introduced utilizing CBSS scores to identify children as Monitors, Blunters, Active, or Passive copers. Using this model, a similar proportion of Active and Passive copers were found in both groups, while the shift towards Blunting in the oncology group was accentuated. Within the oncology group, a positive relationship between Blunting scores and time elapsed since diagnosis was observed, suggesting that the increased Blunting in children with cancer is a reactive phenomenon, at least partly a response to the contingencies of cancer and its' treatment. These findings may provide an alternative interpretation to previous reports of increased defensiveness and repression in children with cancer.

Abstract
Investigated responses of siblings (N = 254) of children with cancer to structured interviews designed to elicit thoughts and feelings about effects of cancer on self and family. Siblings indicated distress about family separations and disruptions, lack of attention, focus of family on the ill child, negative feelings in themselves and family members, cancer treatments and their effects, and fear of death. Siblings also reported becoming more compassionate, families becoming closer, and having experiences they otherwise would not have had. Age and gender differences in responses indicated distinctive perceptions of and vulnerability to the cancer experience. Older siblings were far more likely to report positive effects than younger siblings suggesting that level of maturity can moderate the stress of an ill child within the family.

Abstract
PURPOSE To assess the salvage rate and long-term complications among children treated with an intensive regimen for isolated CNS relapse during first remission of acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS Twelve boys and eight girls, diagnosed at a median age of 4 years, had CNS relapse at a median age of 7 years. Five had CNS leukemia at presentation, while five completed treatment before relapse. First complete remission lasted a median of 22.5 months. Ten patients had received cranial irradiation plus intrathecal (IT) therapy, and the remainder had received high-dose intravenous and/or IT methotrexate (MTX) as CNS-directed treatment. Retrieval therapy consisted of a five-agent intensive reinduction regimen followed by continuation therapy with four rotating drug pairs. Triple-IT therapy was administered weekly for 4 to 5 weeks, then every 6 weeks until craniospinal radiation (cranium, 24 Gy; spine, 15 Gy; both sites, 1.5 Gy per fraction) was administered. RESULTS All 20 children achieved a second complete remission. The 5-year estimate of disease-free survival (mean +/- SE) was 70% +/- 11%. Thirteen patients remain in remission at 71+ to 126+ months (median, 104+), and 10 of 13 patients tested have normal IQ scores. Four patients have had a second relapse (one CNS and three non-CNS), and three have developed other malignancies. Prior cranial irradiation was associated with subsequent failure; only three of 10 patients who previously received radiotherapy, compared with all of the other 10 patients, remained in second remission. CONCLUSION This intensive retrieval therapy is effective and well tolerated by children with an isolated CNS relapse of ALL, especially those who have not received prior cranial irradiation. Most patients have no significant neuropsychologic impairment.

Abstract
PURPOSE An analysis of survival outcome following isolated central nervous system (CNS) relapse treated with craniospinal irradiation (CSI) and additional chemotherapy in children with acute lymphoblastic leukemia (ALL) was conducted. METHODS AND MATERIALS Eighteen of 344 pediatric patients with ALL who attained initial complete remission on the St. Jude Children's Research Hospital "Study XI" prospective protocol (1984-1988) developed a CNS relapse as first adverse event. Median interval to isolated CNS relapse was 7.5 months (range = 2-40 months) after achieving initial complete remission. At diagnosis, 14 of the 18 children were categorized as "high risk" for subsequent leukemic relapse. Preventive cranial irradiation [PCI (18 Gy)] was delivered as planned to one of the 14 "high-risk" children. The other 13 "high-risk" patients experienced a CNS relapse during the first year of continuation therapy prior to week 52 of planned PCI. All four "low-risk" patients experienced a CNS relapse beyond the first year of continuation therapy; none were scheduled to receive PCI. Following isolated CNS relapse, all 18 patients were treated on a prospective contingency of "Study XI" trial consisting of intensified reinduction chemotherapy, weekly intrathecal methotrexate/hydrocortisone/Ara-C x 4-6 injections, craniospinal irradiation (cranium to 24.0 Gy and spine to 15.0 Gy at 1.5 Gy/fraction) and maintenance systemic therapy for a minimum of 1 year. RESULTS Ten of 18 patients remain in continuous complete secondary remission at 17 to 50 months post-CNS relapse. Second sites of relapse in the remaining eight children were as follows: CNS in four, bone marrow in three, and bilateral testicular in one patient. Each of these eight patients died of progressive leukemia. At a median followup of 40 months post-initial CNS relapse, the 3-year secondary Kaplan-Meier survival and event-free survival are 72% and 56%, respectively. Minimal long-term neurotoxicity was associated with the treatment regimen. The most important prognostic factors predicting continuous secondary remission included white blood cell count at diagnosis (p = 0.05), and duration of initial remission (p = 0.04). CONCLUSION This trial demonstrates that more than one-half of patients may be successfully salvaged with intensified chemotherapy and craniospinal irradiation without significant morbidity following an isolated CNS relapse, despite previous multiagent chemotherapy though virtually no prior PCI in childhood ALL.

Abstract
PURPOSE A prospective assessment of neurocognitive performance was conducted in children with acute lymphoblastic leukemia (ALL) following isolated central nervous system (CNS) relapse to evaluate the impact of additional systemic/intrathecal (IT) chemotherapy and craniospinal irradiation (CSI) upon long-term intellectual function. METHODS AND MATERIALS Twenty-one children with ALL manifesting an isolated CNS relapse between 1984 through 1989 underwent serial evaluations of intellectual function. Neurocognitive function was measured by the full-scale intelligence quotient (FSIQ) as determined by the age-appropriate Wechsler Intelligence Scale and by achievement in reading, math, and spelling as assessed by the Wide Range Achievement Test (WRAT). Intelligence testing was initiated following isolated CNS relapse after clearance of cerebrospinal fluid (CSF) cytology but prior to CSI and continued at annual intervals for a minimum of 4 years postmeningeal failure. Protocol treatment for isolated CNS relapse consisted of reinduction and maintenance systemic therapy, intrathecal (IT) triple-agent chemotherapy, and early CSI (cranium to 24 Gy and spine to 15 Gy at 1.5 Gy/fraction) as outlined on the institutional "Total XI" trial. RESULTS All 21 children attained secondary CNS remission and underwent the planned additional systemic/IT chemotherapy and CSI. Fourteen of the 21 children remain in secondary continuous remission, while the remaining 7 experienced a second relapse and were removed from further neurocognitive assessment. For the eight female and six male long-term survivors, mean ages at original diagnosis and at CSI were 5.7 years (range = 0.6-16.2) and 7.0 years (range = 1.8-17.0), respectively. At a median follow-up interval of 4.6 years (ranges 1.7-6.8) post-CNS relapse, comparison of group mean initial to final FSIQs revealed no statistically significant difference between the two measures (94.5 vs. 95.9, respectively, n = 11, p = 0.52). None of the children are functioning in the mentally retarded range. Final FSIQ outcome directly correlated with initial FSIQ (p = 0.00005, n = 11), age at diagnosis (p = 0.009, n = 14), and age at CSI (p = 0.011, n = 14). In addition, change between initial and final FSIQ scores inversely correlated with age at diagnosis (p = 0.009) and age at CSI (p = 0.018) but not with baseline IQ score (p = 0.41). Initial FSIQ scores were not influenced by either age at diagnosis (p = 0.12) or age at CSI (p = 0.14). Final group mean (range) WRAT scores in reading, math, and spelling were measured to be 94.7 (68-132), 95.6 (69-126), and 93.7 (77-122), respectively (n = 13). Final reading and math scores directly correlated with both age at diagnosis (p = 0.01) and age at CSI (p = 0.009). Spelling outcome did not correlate with either age at diagnosis (p = 0.25) or age at CSI (p = 0.24). Nine children are placed in regular classrooms, while the remaining five require a mixed classroom environment. CONCLUSION In our study, children with ALL experiencing an isolated CNS relapse tolerated additional systemic/IT chemotherapy and CSI without apparent deterioration of group serial intellectual scores. However, longitudinal analyses of group intellectual measures obscured the independent impact of initial FSIQ, age at original diagnosis, and age at CSI upon individual neurocognitive outcome. Early and more intensive psychoeducational stimulation may be needed in very young children presenting with low initial FSIQ scores who are treated with CSI and additional chemotherapy following isolated CNS relapse in ALL.

Abstract
Eight infants with choroid plexus carcinomas were treated with surgery, prolonged postoperative chemotherapy and delayed radiation. The results suggest that some infants with choroid plexus carcinomas can be successfully treated with multimodality therapy, even allowing children with less than a gross total resection to have prolonged disease-free intervals.

Abstract
A multisite collaborative study assessed the frequency and intensity of emotional/behavioral distress in siblings of children with cancer. A sample of 254 siblings, aged 4 to 18 years, and their parents completed interviews and self-report measures 6 to 42 (average 22.5) months after diagnosis of cancer in a brother or sister. Matched controls were obtained from respondents to the Child Health Supplement of the National Health Interview Survey administered in 1988 (CHS88). Before diagnosis, the prevalence of parent-reported emotional/behavioral problems among siblings was similar to that in the general population (7.7% vs 6.3%; p = not significant). After diagnosis, prevalence rose to 18% among siblings. When siblings were grouped according to the presence or absence of problems exacerbated by and/or arising after diagnosis, four levels of adaptation, consistent with scores on the Behavior Problem Scales from the CHS88, emerged. This differentiation may help explain inconsistencies in sibling response reported previously and provides a framework for investigating factors that enhance adaptation.

Abstract
PURPOSE To evaluate survival and neurodevelopmental outcomes following radiation therapy in infants and young children with residual or progressive medulloblastoma after primary chemotherapy. PATIENTS AND METHODS Thirteen young patients (< or = 36 months old) with medulloblastoma were treated with preirradiation multiagent chemotherapy and maximal surgical resection. Patients were scheduled to receive radiation therapy at the time of documented disease progression or upon completion of chemotherapy with residual disease. All patients underwent neurodevelopmental evaluation at the time of diagnosis, before receiving radiation therapy, and at yearly intervals posttreatment. RESULTS Two patients completed the scheduled chemotherapy with residual disease and received delayed radiation therapy. The remaining 11 patients had either local or leptomeningeal progression during chemotherapy (median time to progression, 5 months). Six patients had a complete response (CR) to radiation therapy, and three of these children are alive 48 to 104 months postdiagnosis. Of the five patients who had progressive disease (PD) during radiation therapy or residual imaging abnormalities after treatment, only one is alive (with stable enhancing leptomeningeal abnormalities) 48 months postirradiation. Two additional survivors were rendered disease-free by surgical resection before radiation therapy and are without evidence of disease at 91 and 107 months after diagnosis. Thus, six of 13 patients are alive at 48 to 107 months postdiagnosis. Neurodevelopmental scores tended to be below age norms at diagnosis; scores improved during chemotherapy, but then decreased during posttreatment follow-up evaluation. CONCLUSION Radiation therapy appears to produce long-term disease-free survival in a proportion of very young patients who have progressive or residual medulloblastoma during or after primary chemotherapy. However, neurodevelopmental deficits are frequent among long-term survivors.

Abstract
In order to describe the status of long-term survivors of brain stem glioma, neuropsychological and behavioral measures were obtained a median of 2.5 (range 1.5-5.6) years after diagnosis from 16 survivors of 51 consecutively diagnosed children with brain stem glioma between 1983 and 1991. Among 11 children with dorsally exophytic tumors, 7 were treated with surgery alone (SRG) and 4 received conventionally fractionated local cranial radiation therapy (CFRT; 54-56 Gy) to the brain stem following surgery, 3 of these because of recurrent disease. Five others with diffusely infiltrative brain stem tumors received hyperfractionated radiation therapy (HFRT; 70.2 Gy) to the brain stem; 4 following biopsy or limited resection and 1 without prior surgery. IQs of children in the CFRT (mean 89, SD 24.4) and HFRT (mean 85, SD 12.7) groups were not significantly different. Children in the SRG group had significantly higher IQs (mean 100, SD 11.0) and fewer neurologic deficits than those who had received CFRT or HFRT. However, after statistically controlling for severity of neurologic deficits, treatment had no effect on IQ. The severity of residual neurologic deficits accounted for 42% of the variance in IQ scores; children with fewer neurologic problems scored higher. Additional studies are required to evaluate the potential neuropsychological benefits of equivalent total doses of HFRT compared to CFRT.

Abstract
We prospectively studied the efficacy and adverse effects of chlorpromazine (30 mg/m2 given intravenously) plus lorazepam (0.04 mg/kg given intravenously) versus chlorpromazine alone in a controlled, double-blind, randomized, parallel-design investigation in 25 children (1.5 to 17.3 years of age) with acute lymphoblastic leukemia. Response to other antiemetics in eight children refusing random assignment to treatment was also evaluated. All children were receiving intravenous infusions of teniposide plus cytarabine, the pharmacokinetics of which were characterized for each of the one to four courses. There were no differences between the 11 patients randomly assigned to receive chlorpromazine alone and the 14 randomly assigned to receive lorazepam plus chlorpromazine in the number of emesis episodes (6.0 vs 5.9; p = 0.53), frequency of dystonic reactions (3% vs 5%), or akathisia (13 vs 10%). The only serious adverse event, symptomatic hypotension, occurred in a boy receiving chlorpromazine plus lorazepam. An exploratory pharmacodynamic analysis revealed that the only variable that correlated with vomiting was cytarabine 1 1/2-hour plasma concentration (p = 0.007). Children who received either chlorpromazine plus lorazepam or chlorpromazine alone had fewer episodes of vomiting than those who received "conventional" antiemetic therapy (6.0 vs 8.6; p = 0.01). We conclude that the severity of emesis is related to the plasma concentration of cytarabine; that intravenously administered chlorpromazine is as effective as chlorpromazine plus lorazepam in preventing chemotherapy-induced vomiting; and that the potential for adverse effects with the addition of lorazepam may be a disadvantage.

Abstract
Children's and parent's subjective ratings of the frequency and severity of nausea and emesis were assessed among 33 children with acute lymphoblastic leukemia receiving identical chemotherapy. Parents were trained to record the frequency of the child's actual emesis episodes during chemotherapy. Although parent and child ratings of nausea were significantly correlated, children generally rated their nausea and emesis as more frequent and more severe than did their parents. Parent ratings showed inadequate external validity when compared with behavioral observations. Children with greater anxiety and higher subjective ratings subsequently exhibited more frequent episodes of emesis by observation, suggesting that their perceptions of symptoms based on previous chemotherapy experiences may predict emesis during different chemotherapy. In a stepwise multiple regression analysis, antiemetic regimen and the child's anxiety as rated by the parent combined to account for approximately 47% of the variance in number of episodes of emesis. These findings are discussed in the context of factors limiting validity of parent and child reports of children's symptomatology with implications for future epidemiologic and intervention research.

Abstract
We compared the cognitive functioning of seven children with left and seven children with right temporal lobe tumors one year or more following completion of medical intervention (surgical resection + radiation therapy). No differences were found between the two groups with respect to verbal IQ, performance IQ.full scale IQ, verbal minus performance IQ, or verbal comprehension, perceptual organization, or freedom from distractability factor scores. After adjusting memory test results for variance attributable to general intelligence, three children with left and four children with right temporal tumors exhibited specific auditory-verbal memory dysfunction; five of these children had concurrent visual-verbal memory dysfunction. Children receiving radiation therapy to the tumor were at significantly greater risk for verbal memory problems. Reading and spelling achievement were significantly correlated with verbal memory performance. Inconsistent association between cerebral hemisphere of tumor and type of cognitive deficit may be related to the relatively slow progression of the tumor and regional interventions such as radiation therapy. Nevertheless, the results of the present report suggest that the majority of children diagnosed with temporal lobe tumors are at increased risk for memory dysfunction and academic failure.

Abstract
BACKGROUND Among patients with malignant brain tumors, infants and very young children have the worst prognosis and the most severe treatment-related neurotoxic effects. Therefore, in 1986, the Pediatric Oncology Group began a study in which postoperative chemotherapy was given in order to permit a delay in the delivery of radiation to the developing brain. METHODS Children under 36 months of age with biopsy-proved malignant brain tumors were treated postoperatively with two 28-day cycles of cyclophosphamide plus vincristine, followed by one 28-day cycle of cisplatin plus etoposide. This sequence was repeated until the disease progressed or for two years in 132 children 24 months of age at diagnosis and for one year in 66 children 24 to 36 months of age at diagnosis. After this, the patients received radiation therapy. The response to the first two cycles of chemotherapy was measured in 102 patients with residual postoperative disease. RESULTS The first two cycles of cyclophosphamide and vincristine produced complete or partial responses in 39 percent of the 102 patients who could be evaluated. The response rates were highest among patients with medulloblastomas, malignant gliomas, or ependymomas. Patients with brain-stem gliomas or embryonal tumors (primitive neuroectodermal tumors) had little or no response. The progression-free survival rate was 41 percent at one year for children who were 24 to 36 months old at diagnosis and 39 percent at two years for those under 24 months of age at diagnosis. Multivariate analysis identified embryonal tumors as a significant adverse prognostic feature (relative risk, 2.2; 95 percent confidence interval, 1.4 to 3.4) and complete resection as a favorable feature (relative risk, 0.33; 95 percent confidence interval, 0.20 to 0.54). Complete responses to chemotherapy were associated with a progression-free survival rate approaching that achieved with gross total resection. A comparison of cognitive evaluations obtained at base line and after one year of chemotherapy revealed no evidence of deterioration in cognitive function. CONCLUSIONS Chemotherapy appears to be an effective primary postoperative treatment for many malignant brain tumors in young children. Disease control for one or two years in a large minority of patients permitted a delay in the delivery of radiation and, on the basis of preliminary results, a reduction in neurotoxicity. For patients who had undergone total surgical resection or who had a complete response to chemotherapy, the results are sufficiently encouraging to suggest that radiation therapy may not be needed in this subgroup of children after at least one year of chemotherapy.

Abstract
Compared the psychological adjustment of 81 children with brain tumors to that of 31 control children with various malignancies not involving the central nervous system. Both groups exhibited significantly increased frequencies of elevations on one or more age- and gender-corrected Social Competence and Behavior Problems scales of the Child Behavior Checklist (CBCL) relative to normative expectations. Comparison of the Brain Tumor and Cancer Control groups revealed no significant differences on any CBCL scale. Among children diagnosed with brain tumors, stepwise multiple regression analyses revealed that low child IQ, residence in a single-parent family, moderate to severe disfigurement, low SES, tumor location, and severe functional impairment were associated with decreased Social Competence scores. Elevated Behavior Problems scores were associated with younger maternal age at the child's birth, tumor location, and residence in a single-parent family. Results reinforce the need to consider complex relationships between demographic characteristics of the child's family, type of brain damage, and the cosmetic and functional status of the child in determining acute psychological adjustment of brain-damaged children.
