Treatment-related calvarial lesions in pediatric brain tumor survivors.
Ontology highlight
ABSTRACT: Background
Despite improved survival, many pediatric brain tumor survivors receiving radiation therapy (RT) experience late effects.Procedure
To study calvarial lesions in this population, we retrospectively reviewed records of patients undergoing neurosurgical evaluation for calvarial bone lesions detected in posttreatment follow-up imaging at St. Jude Children's Research Hospital. Primary tumor diagnosis, treatment, imaging, surgical intervention, and histopathology from patients with radiographic evidence of lesions followed for ≥2 years post-RT were studied.Results
For 17 patients with 18 index lesions, median time to lesion manifestation was 2.34 years. Medulloblastoma patients developed lesions at a shorter interval from RT than ependymoma patients (P = .05). Twelve of 14 lesions requiring surgery were benign fibro-osseous or sclerotic. Two malignant lesions distinct from the primary tumor had genetic predisposition to malignancy.Conclusion
Most calvarial lesions arising post-RT are benign and fibro-osseous. Serial imaging is recommended, and high index of suspicion for malignant lesions is warranted for patients genetically predisposed to cancer.

Project description:ObjectiveBrain tumors during childhood may disrupt the development and maintenance of friendships due to the impact of disease- and treatment-related factors on functioning. The goal of this study was to determine if children treated for either a brain tumor or a non-central nervous system (CNS) solid tumor could name a friend and to evaluate the social information processes associated with the ability to name a friend.MethodYouth (ages 7-14) treated for either a brain tumor (n = 47; mean age = 10.51 years) or a non-CNS solid tumor (n = 34; mean age = 11.29) completed an assessment within 6 months of the conclusion of treatment that included asking participants to name a friend and completing measures of social information processing (SIP). Rates of self-reported friendship were compared between groups and correlates of being able to name a friend were evaluated.ResultsYouth treated for a brain tumor (61.7%) were significantly less likely to name a friend compared with youth treated for a non-CNS solid tumor (85.3%). Diagnosis type (brain vs. non-CNS), relapse status, attribution style, and facial affect recognition were significant predictors of being able to name a friend or not in a logistic regression model.ConclusionsYouth treated for a brain tumor and those who experienced a disease relapse are at risk for impairments in friendships; difficulties with SIP may increase this risk. Targeted screening and intervention efforts for children diagnosed with brain tumors and those who have relapsed could address difficulties with peers.

Project description:BackgroundPediatric brain tumor survivors (PBTS) are at risk of worse quality of life (QOL) due to the impact of neurotoxic treatments on the developing nervous system. Parenting factors such as protectiveness have been linked to worse QOL in childhood cancer survivors generally, but have yet to be explored for PBTS. We examined whether parenting behaviors moderated the association between neurotoxic treatment and QOL for PBTS.MethodsPBTS (n = 40; ages 10-25) and their caregivers (n = 47) completed measures of parenting behaviors including warmth (support/connectedness) and psychological control (protectiveness) and QOL. We divided the sample into moderate/high and low neurotoxicity groups based on chart review using the Pediatric Neuro-Oncology Rating of Treatment Intensity and examined moderator effects.ResultsSurvivor-reported primary caregiver warmth moderated the relationship between neurotoxicity and caregiver-reported QOL. Moderate/high neurotoxicity was associated with lower caregiver-reported QOL only when survivor-reported primary caregiver warmth was low, P = .02. Similar results were found for survivor-reported QOL. Caregiver-reported psychological control moderated the association between neurotoxicity and caregiver-reported QOL such that neurotoxicity only affected QOL at high levels of psychological control, P = .01.ConclusionsHeightened associations between parenting and QOL in the context of neurotoxic treatments underscore the need to better support PBTS. Findings are consistent with research suggesting that family factors may be particularly important for children with other neurological insults. Limitations include cross-sectional design and a small/heterogeneous clinical sample with low ethnic/racial diversity. Prospective studies are needed to refine evidence-based screening and develop psychosocial intervention strategies to optimize QOL for PBTS and their families.

Project description:PurposeThe neurocognitive outcomes of pediatric brain tumor survivors have been extensively studied but the risk and predictors for neurobehavioral impairment are less clearly defined. We systematically analyzed the rates of emotional, psychosocial, and attention problems in pediatric brain tumor survivors.MethodsPubMed, Web of Science, Embase, Scopus, and Cochrane were searched for articles published between January 2012 to April 2022. Eligible studies reported neurobehavioral outcomes for PBTS aged 2 to <23 years with a brain tumor diagnosis before 18 years of age. A random-effect meta-analysis was performed in R.ResultsThe search yielded 1187 unique publications, of which 50 were included in the quantitative analysis. The estimated risk of having emotional, psychosocial, and attention problems were 15% (95%CI 10-20%), 12% (95%CI 9-16%), and 12% (95%CI 9-16%), respectively. PBTS were more likely to have emotional difficulties (Hedge's g = 0.43 [95%CI 0.34-0.52]), psychosocial problems (Hedge's g = 0.46 [95%CI 0.33-0.58]), and attention problems (Hedge's g = 0.48 [95%CI 0.34-0.63]) compared to normal/healthy control subjects. There was no significant difference in the rates of neurobehavioral impairment between children with and without history of cranial radiotherapy.ConclusionsPBTS are at elevated risk of neurobehavioral impairment. Neurobehavioral monitoring should be considered as the standard of care for PBTS.

Project description:PurposeWith more children surviving a brain tumor, neurocognitive consequences of the tumor and its treatment become apparent, which could affect psychosocial functioning. The present study therefore aimed to assess psychosocial functioning of pediatric brain tumor survivors (PBTS) in detail.MethodsPsychosocial functioning of PBTS (8-18 years) with parent-reported neurocognitive complaints was compared to normative data on health-related quality of life (HRQOL), self-esteem, psychosocial adjustment, and executive functioning (one-sample t tests) and to a sibling control group on fatigue (independent-samples t test). Self-, parent-, and teacher-report questionnaires were included, where appropriate, providing complementary information.ResultsEighty-two PBTS (mean age 13.4 years, SD 3.2, 49 % males) and 43 healthy siblings (mean age 14.3, SD 2.4, 40 % males) were included. As compared to the normative population, PBTS themselves reported decreased physical, psychological, and generic HRQOL (d = 0.39-0.62, p < 0.008). Compared to siblings, increased fatigue-related concentration problems (d = 0.57, p < 0.01) were reported, although self-reported self-esteem and psychosocial adjustment seemed not to be affected. Parents of PBTS reported more psychosocial (d = 0.81, p < 0.000) and executive problems (d = 0.35-0.43, p < 0.016) in their child than parents of children in the normative population. Teachers indicated more psychosocial adjustment problems for female PBTS aged 8-11 years than for the female normative population (d = 0.69, p < 0.025), but they reported no more executive problems.ConclusionsPBTS with parent-reported neurocognitive complaints showed increased psychosocial problems, as reported by PBTS, parents, and teachers.Implications for cancer survivorsSystematic screening of psychosocial functioning is necessary so that tailored support from professionals can be offered to PBTS with neurocognitive complaints.

Project description:The purposes of this study were to determine the incidence of neurovascular events as late complications in pediatric patients with brain tumor and to evaluate radiation as a risk factor.Patients were ascertained using the tumor database of a pediatric tertiary care center. Included patients had a primary brain tumor, age birth to 21 years, initial treatment January 1, 1993, to December 31, 2002, and at least 2 visits with neuro-oncology. Radiation exposure included: whole brain, whole brain plus a focal boost, or focal brain. The primary outcome was stroke or transient ischemic attack.Of 431 subjects, 14 had 19 events of stroke or transient ischemic attack over a median follow-up of 6.3 years. The incidence rate was 548/100 000 person-years. Overall, 61.5% of subjects received radiation, including 13 of 14 subjects with events. Median time from first radiation to first event was 4.9 years. The stroke/transient ischemic attack hazard ratio for any brain irradiation was 8.0 (95% CI, 1.05-62; P=0.045); for the circle of Willis, radiation was 9.0 (95% CI, 1.2-70; P=0.035); and for focal noncircle of Willis, radiation was 3.4 (95% CI, 0.21-55; P=0.38).The incidence of neurovascular events in this population is 100-fold higher than in the general pediatric population and cranial irradiation is an important risk factor. By defining the incidence of this late effect, physicians are better able to counsel parents regarding treatment, monitor patients at risk, and target a population for primary stroke prevention in future studies.

Project description:ᅟ: Pediatric brain tumor survivors are at risk for significant difficulties related to social competence. Little research has examined factors that contribute to survivor social problems.PurposeThe current study is grounded in a model of social competence for youth with brain disorder and used qualitative and quantitative methods to obtain caregiver perspectives on survivor social competence and identify pertinent risk and resistance factors.MethodsThe study occurred in two phases, including focus groups with 36 caregivers of 24 survivors and confirmatory interviews with 12 caregivers of 12 survivors.ResultsQualitative content analyses resulted in three themes that were illustrative of the model of social competence. Themes included (1) the impact of survivor sequelae on social function; (2) the role of family in evaluating and promoting survivor social development; and (3) the match between the survivor's social context and developmental needs. Quantitative data supported the associations between survivor social skills, survivor executive function, and family functioning.ConclusionsOverall, findings underscore the influence of risk and resistance factors across different systems on survivor social competence and suggest directions for future research and intervention efforts.

Project description:ObjectiveSurvivors of pediatric brain tumors (SPBT) are at risk for social deficits, fewer friendships, and poor peer relations. SPBT also experience reduced brain connectivity via microstructural disruptions to white matter from neurological insults. Research with other populations implicates white matter connectivity as a key contributor to poor social functioning. This case-controlled diffusion-weighted imaging study evaluated structural connectivity in SPBT and typically developing controls (TDC) and associations between metrics of connectivity and social functioning.MethodsDiffusion weighted-imaging results from 19 SPBT and 19 TDC were analyzed using probabilistic white matter tractography. Survivors were at least 5 years post-diagnosis and 2 years off treatment. Graph theory statistics measured group differences across several connectivity metrics, including average strength, global efficiency, assortativity, clustering coefficient, modularity, and betweenness centrality. Analyses also evaluated the effects of neurological risk on connectivity among SPBT. Correlational analyses evaluated associations between connectivity and indices of social behavior.ResultsSPBT demonstrated reduced global connectivity compared to TDC. Several medical factors (e.g., chemotherapy, recurrence, multimodal therapy) were related to decreased connectivity across metrics of integration (e.g., average strength, global efficiency) in SPBT. Connectivity metrics were related to peer relationship quality and social challenges in the SPBT group and to social challenges in the total sample.ConclusionsMicrostructural white matter connectivity is diminished in SPBT and related to neurological risk and peer relationship quality. Additional neuroimaging research is needed to evaluate associations between brain connectivity metrics and social functioning in SPBT.

Project description:Intensified therapy with platinum-based regimens for pediatric brain tumors has dramatically increased the number of pediatric brain tumor survivors (PBTS) but frequently causes permanent sensorineural hearing loss (SNHL). Although neurocognitive decline in PBTS is known to be associated with radiation therapy (RT), SNHL represents a potential additional contributor whose long-term impact has yet to be fully determined.The neurocognitive impact of significant SNHL (Chang scale ? 2b) in PBTS was assessed through a retrospective cohort study of audiograms and neurocognitive testing. Scores for neurocognitive domains and subtest task performance were analyzed to identify specific strengths and weakness for PBTS with SNHL.In a cohort of PBTS (n = 58) treated with platinum therapy, significant SNHL was identified in more than half (55%, n = 32/58), of which the majority required hearing aids (72%, 23/32). RT exposure was approximately evenly divided between those with and without SNHL. PBTS were 6.7 ± 0.6 and 11.3 ± 0.7 years old at diagnosis and neurocognitive testing, respectively. In multivariate analyses adjusted for RT dose, SNHL was independently associated with deficits in intelligence, executive function, and verbal reasoning skills. Subtests revealed PBTS with SNHL to have poor learning efficiency but intact memory and information acquisition.SNHL in PBTS increases the risk for severe therapy-related intellectual and neurocognitive deficits. Additional prospective investigation in malignant brain tumors is necessary to validate these findings through integration of audiology and neurocognitive assessments and to identify appropriate strategies for neurocognitive screening and rehabilitation specific to PBTS with and without SNHL.

Project description:BackgroundThe purpose of this analysis is to report long-term health-related quality of life (HRQoL) among brain tumor survivors treated with proton therapy (PRT) at a very young age.MethodsFifty-nine children <4 years old received PRT between 2000 and 2011. Forty families participated. HRQoL was assessed by child self-report (CSR; age ≥5) and parent proxy report (PPR; age 2+) using the PedsQL Core.ResultsThe median age was 2.5 years (range, 0.3-3.8) at PRT and 9.1 years (5.5-18) at last follow-up. The most common diagnoses were ependymoma (n = 22) and medulloblastoma (n = 7). Median follow-up is 6.7 years (3-15.4). Follow-up mean CSR and PPR scores were: total core (78.4 and 72.9), physical (82.9 and 75.2), psychosocial (76.0 and 71.6), emotional (74.4 and 70.7), social (81.2 and 75.1), and school (72.4 and 69.9). Parent-reported HRQoL fell within a previously defined range for healthy children in 37.5% of patients, and for children with severe health conditions in 45% of patients. PPR HRQoL was stable from baseline to last follow-up among all domains except for social functioning. History of gastrostomy tube was significantly associated with poorer CSR and PPR HRQoL on multivariable analysis. Ninety percent of children functioned in a regular classroom, 14 (36%) used a classroom aid, 9 (23%) used an outside tutor, and 18 (46%) had an individualized education plan.ConclusionLong-term HRQoL among brain tumor survivors treated with PRT at a very young age is variable, with over a third achieving HRQoL levels commensurate with healthy children.Key points1. One third of survivors reported long-term HRQoL scores comparable to those of healthy children.2. Treatment for hydrocephalus or a feeding tube was associated with significantly lower HRQoL.3. Total core HRQoL scores remained stable from baseline to last follow-up.

Project description:BackgroundPediatric brain tumor survivors (PBTS) experience disease- and treatment-related sequelae. We aimed to investigate the occurrence of participation limitations, impairments in functioning, fatigue, and the association between patient, tumor- and treatment-related factors and these outcomes.MethodsChildren (4-18 years) after treatment for a brain tumor between 2005 and 2014 at the Erasmus Medical Center, Rotterdam, the Netherlands, were eligible. The parent-reported Child and Family Follow-up Survey developed to measure participation and impairments in functioning in youth with acquired brain injury, was used. Fatigue was assessed using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale. Associations with patient, tumor- and treatment-related factors were explored using univariable analyses.ResultsNinety-one PBTS (median age: 11.3 years [range: 9.5-14.1], time since treatment: 3.9 years [range: 4-6.2]) were included (response rate: 55%). Participation limitations were reported in 53% and were associated with impairments in functioning (15-67%) (P ≤ .01) and fatigue (P ≤ .03).Parent- and child-reported fatigue was increased compared to normative values (P ≤ .02). History of hydrocephalus was associated with increased fatigue (P ≤ .04). Younger age at diagnosis and longer time since diagnosis were associated with impairments in functioning and cognitive fatigue (P < .05).Participation limitations, impairments in functioning and fatigue were similar in PBTS who were <3 or ≥3 years since completion of treatment.ConclusionMore than half of PBTS reported limited participation ability, which is associated with impairments in functioning and fatigue. The complication hydrocephalus seems to lead to more fatigue. Participation limitations, impairments in functioning and fatigue appear not to diminish in the longer term.
