Asking those who know their needs best: A framework for active engagement and involvement of childhood cancer survivors and parents in the process of psychosocial research-A workshop report.

BACKGROUND: Patient and public involvement and engagement (PPIE) in healthcare research is crucial for effectively addressing patients' needs and setting appropriate research priorities. However, there is a lack of awareness and adequate methods for practicing PPIE, especially for vulnerable groups like childhood cancer survivors. AIMS: This project aimed to develop and evaluate engagement methods to actively involve pediatric oncological patients, survivors, and their caregivers in developing relevant research questions and practical study designs. METHODS AND RESULTS: An interdisciplinary working group recruited n = 16 childhood cancer survivors and their caregivers to work through the entire process of developing a research question and a practicable study design. A systematic literature review was conducted to gather adequate PPIE methods which were then applied and evaluated in a series of three workshop modules, each lasting 1.5 days. The applied methods were continuously evaluated, while a monitoring group oversaw the project and continuously developed and adapted additional methods. The participants rated the different methods with varying scores. Over the workshop series, the participants successfully developed a research question, devised an intervention, and designed a study to evaluate their project. They also reported increased expertise in PPIE and research knowledge compared to the baseline. The project resulted in a practical toolbox for future research, encompassing the final workshop structure, evaluated methods and materials, guiding principles, and general recommendations. CONCLUSION: These findings demonstrate that with a diverse set of effective methods and flexible support, actively involving patients, survivors, and caregivers can uncover patients' unmet disease-related needs and generate practical solutions apt for scientific evaluation. The resulting toolbox, filled with evaluated and adaptable methods (workbook, Supplement 1 and 2), equips future scientists with the necessary resources to successfully perform PPIE in the development of health care research projects that effectively integrate patients' perspectives and address actual cancer-related needs. This integration of PPIE practices has the potential to enhance the quality and relevance of health research and care, as well as to increase patient empowerment leading to sustainable improvements in patients' quality of life.

The oracle of D-A-Ch - Results of a Delphi Survey for the development of the evidence- and consensus-based tool "My Logbook".

OBJECTIVE: The present report describes the results of four delphi surveys conducted within the quality improvement project "My Logbook" which aims to translate evidence-based standards for psychosocial care in pediatric oncology into a practical consensus-based tool. METHODS: In four consecutive delphi surveys a total of n=153 international, multi-disciplinary experts rated the content, method, and design of the different booklets of "My Logbook" which a local expert group had conceptualized. After each survey, the feedback was incorporated, and the changes were evaluated in a final consensus vote by the quality assurance panel of the PSAPOH. RESULTS: While some surveys led to a review on a page level, most booklets as a whole reached the consensus-level of approval. Over the course of the surveys, any revisions and comments were incorporated in the booklets, and approval rates increased steadily. DISCUSSION: The delphi surveys ensured the integration of multi-disciplinary, international expertise, uncovering issues such as language barriers and the need for a user manual that would not have been evident in first line . The incorporation of the input led to a continuous improvement of the tool, reflected in steadily increasing acceptance rates in the consecutive survey rounds. CONCLUSION: The incorporation of the expert input as well as the additional development of a user manual resulted in a final version of the "My Logbook" apt for the interdisciplinary application in pediatric oncology in the entire DACH-region.

Sustained Survival Benefit in Recurrent Medulloblastoma by a Metronomic Antiangiogenic Regimen: A Nonrandomized Controlled Trial.

Importance: Medulloblastoma recurrence in patients who have previously received irradiation has a dismal prognosis and lacks a standard salvage regimen. Objective: To evaluate the response rate of pediatric patients with medulloblastoma recurrence using an antiangiogenic metronomic combinatorial approach (Medulloblastoma European Multitarget Metronomic Anti-Angiogenic Trial [MEMMAT]). Design, Setting, and Participants: This phase 2, investigator-initiated, multicenter nonrandomized controlled trial assessed 40 patients with relapsed or refractory medulloblastoma without a ventriculoperitoneal shunt who were younger than 20 years at original diagnosis. Patients were enrolled between April 1, 2014, and March 31, 2021. Interventions: Treatment consisted of daily oral thalidomide, fenofibrate, celecoxib, and alternating 21-day cycles of low-dose (metronomic) oral etoposide and cyclophosphamide, supplemented by intravenous bevacizumab and intraventricular therapy consisting of alternating etoposide and cytarabine. Main Outcomes and Measures: The primary end point was response after 6 months of antiangiogenic metronomic therapy. Secondary end points included progression-free survival (PFS), overall survival (OS), and quality of life. Adverse events were monitored to assess safety. Results: Of the 40 patients (median [range] age at treatment start, 10 [4-17] years; 25 [62.5%] male) prospectively enrolled, 23 (57.5%) achieved disease control after 6 months of treatment, with a response detected in 18 patients (45.0%). Median OS was 25.5 months (range, 10.9-40.0 months), and median PFS was 8.5 months (range, 1.7-15.4 months). Mean (SD) PFS at both 3 and 5 years was 24.6% (7.9%), while mean (SD) OS at 3 and 5 years was 43.6% (8.5%) and 22.6% (8.8%), respectively. No significant differences in PFS or OS were evident based on molecular subgroup analysis or the number of prior recurrences. In patients demonstrating a response, mean (SD) overall 5-year PFS was 49.7% (14.3%), and for patients who remained progression free for the first 12 months of treatment, mean (SD) 5-year PFS was 66.7% (16.1%). Treatment was generally well tolerated. Grade 3 to 4 treatment-related adverse events included myelosuppression, infections, seizures, and headaches. One heavily pretreated patient with a third recurrence died of secondary acute myeloid leukemia. Conclusions and Relevance: This feasible and well-tolerated MEMMAT combination regimen demonstrated promising activity in patients with previously irradiated recurrent medulloblastoma. Given these results, this predominantly oral, well-tolerated, and outpatient treatment warrants further evaluation. Trial Registration: ClinicalTrials.gov Identifier: NCT01356290.

Bridging the gap: A quality improvement project to implement psychosocial care standards into clinical practice in pediatric oncology.

BACKGROUND: Psychosocial guidelines and standards systematically describe stressors and resources in particularly challenging situations and hence serve as a basis for interventions to achieve defined psychosocial goals. Despite fundamental principles and guidelines for psychosocial methods, the quality of provided care varies considerably depending on setting, provision, and profession. The purpose of the present protocol is to illustrate the development and evaluation of the standardized psychological intervention "My Logbook", a practical guide accompanying children through all stages of treatment by directly translating current quality standards of psychosocial care into practice. METHODS: In an evidence-based set-up, using face-to-face discussions and telephone conferences, a multi-professional team of local experts decide on critical disease-related issues, structure, content (information and intervention elements) and design of the quality improvement tool. Via delphi surveys an extended expert team is asked to rate the content, method, and design of all booklets which is concluded by a final agreement by the specialist group for quality assurance of the psychosocial working group in the Society for Pediatric Oncology (PSAPOH). The developed tools are piloted in an international multicenter study to evaluate the patient-reported outcome and feasibility and to integrate practical views of patients, as well as psychosocial and interdisciplinary professionals into the further development of the "My Logbook". DISCUSSION: The iterative development of the "My Logbook" including local and international experts as well as the patient and practical perspective allow for the design of a process-oriented, consensus - and evidence-based tool directly translating the S3-Guideline into clinical practice. Feasibility and applicability are fostered through an iterative process of constant evaluation and adaptation of the tool by international experts and through the clinical experience gathered in the multi-centered pilot study. Furthermore, the systematic evaluation of the tool by patients, psychosocial, and interdisciplinary professionals enables the identification of persisting gaps between evidence-based standards and clinical practice, discrepancies between the various stakeholders' perspectives as well as regional differences in feasibility, thereby directly linking practice and research. The preliminary results emphasize that psychological support can be standardized, enabling an evaluation and optimization of psychosocial care which future studies need to assess in multicenter clinical randomized controlled trials.

Embracing paediatric palliative care in paediatric oncology from diagnosis onwards.

Paediatric palliative care aims to support children and young people with life-limiting or life-threatening conditions, and their families, from the time of diagnosis. Early integration within oncology has been recognised as having benefits for all involved, whatever the outcome may be. Through improved communication and advance care planning, it enables user-centred care, where concerns about quality of life, preferences and values are given the same relevance as cutting-edge therapy. Challenges to the integration of palliative care within paediatric oncology include raising awareness and providing education, whilst searching for the best care model and adapting to an ever-changing therapeutic scenario.

Good to know - This is PPIE! Development of a training tool for public and patient involvement and engagement in pediatric oncological research.

BACKGROUND: Public and Patient Involvement and Engagement (PPIE) in research is still a poorly understood and infrequently practiced concept, although the literature stresses clear benefits for quality of care and research as well as patient satisfaction and empowerment. AIM: The presently described project aimed at using different PPIE methods to evaluate the current state of knowledge about and attitude toward PPIE in research among different stakeholders of pediatric oncology in Europe. Based on the findings a tailored training tool directed toward the different stakeholders will be designed. METHODS AND RESULTS: An interdisciplinary steering group developed a mixed-method 3-stage process to (1) investigate the current knowledge and attitudes about PPIE using a Europe-wide cross-sectional online survey directed toward health care professionals (n = 134) and the patient group (patients, survivors, family members, …) (n = 168). The results were analyzed quantitatively, focusing on group comparisons (t-tests, X2 tests). (2) In a live workshop with n = 36 participants (HCPs and patient group) dual moderation teams (HCPs and patient experts) guided the exploration of effective ways for practicing PPIE. Despite classifying PPIE as relevant, both HCPs and patients indicated a low level of knowledge about the concept and terminology (patients: t(334) = -2.82, p = .004; HCPs: t(270) = -2.88, p = .004). While HCPs assumed to already be involving patients in many research areas, this was not perceived by the patient group (X2 (1, N = 304) = 42.70, p < .001). HCPs and patients named similar obstacles for implementing PPIE in research, though numerous creative solutions were found during the workshop (engagement). (3) The outcomes were integrated into a training tool (White-Board movie). CONCLUSION: Although HCPs and patients acknowledge the benefit of PPIE, the presented results highlight the lack of awareness about the concept, and the need for effective tools for researchers to integrate PPIE throughout the entire research process, thereby contributing to a sustainable change within the scientific culture.

Initial Evidence for Positive Effects of a Psychological Preparation Program for MRI "iMReady" in Children with Neurofibromatosis Type I and Brain Tumors-How to Meet the Patients' Needs Best.

To provide an effective alternative to sedation during MRI examinations in pediatric cancer and NF1 patients, the aims of the present study were to (1) exploratively evaluate a behavioral MRI training program, to (2) investigate potential moderators, as well as to (3) assess the patients' well-being over the course of the intervention. A total of n = 87 patients of the neuro-oncology unit (mean age: 6.83 years) underwent a two-step MRI preparation program, including training inside the scanner, and were recorded using a process-oriented screening. In addition to the retrospective analysis of all data, a subset of 17 patients were also analyzed prospectively. Overall, 80% of the children receiving MRI preparation underwent the MRI scan without sedation, making the success rate almost five times higher than that of a group of 18 children that opted out of the training program. Memory, attentional difficulties, and hyperactivity were significant neuropsychological moderators for successful scanning. The training was associated with favorable psychological well-being. These findings suggest that our MRI preparation could present an alternative to sedation of young patients undergoing MRI examinations as well as a promising tool for improving patients' treatment-related well-being.

A Psychosocial Support Program for Young Adult Childhood Cancer Survivors in Austria: a Qualitative Evaluation Study.

Many adolescents and young adult (AYAs) childhood cancer survivors face disease- or therapy-related late-effects, which limit their participation in various areas of daily life. AYAs are often left alone in our health care system, and many worry about their ability to cope with long-term sequelae, and some are even lost to follow-up. Therefore, in the present study, a targeted aftercare program was developed and evaluated with the goal of facilitating three important "life skills": (1) self-perception, (2) social interaction and conflict management, and (3) self-conscious communication of support needs. A total of n = 13 participants (19.2-30.2 years, mean age 22.8 years) completed a 3-day aftercare seminar, at the end of which each participant wrote a reflection letter ("letter to my future self"), elaborating on observed effects of the seminar, applicability of the given information in daily life, and the direct impact of the seminar on their individual circumstances. The reflection letters were analyzed using qualitative content analysis. All target life skills were mentioned in the reflection letters. The participants reported individual benefits from the program especially with respect to self-perception and self-confidence, giving and taking feedback, and acceptance of personal strengths and weaknesses. Moreover, the feeling of "not being alone" was associated with the survivors' experience of emotional and social support. This evaluation highlights the potential of a one weekend aftercare seminar to address important life skills that are known to positively influence health behavior in AYAs. The detailed description of the seminar can serve as a basis for making this kind of aftercare accessible for other people in similar circumstances.

Sociocultural variables have a major impact on participation in patients treated for paediatric posterior fossa tumours.

BACKGROUND: This study investigates the severeness of participation barriers in patients surviving paediatric posterior fossa tumours (PFT) many years after treatment. In the past, aetiological studies on adverse outcome have primarily focused on pathobiological risk factors. The current analysis aims to investigate the importance of environmental variables. METHODS: On average, 10 years after diagnosis, educational and social difficulties of 42 patients surviving paediatric PFT (mean age 17 years) were inquired using a self-constructed questionnaire following the Psychosocial Resource-Orientated Assessment (PREDI). Educational or social participation barriers were defined by self- and/or proxy-reported difficulties in school or in peer relationships. Accordingly, the children and adolescents were categorized into groups of adequate and limited participation. Subsequently, the study identified potential pathobiological (treatment type, hydrocephalus, tumour relapse, gender, age at diagnosis, seizures and cerebellar mutism) and environmental (parental and maternal education, siblings, main language, discrepancies between personal and environmental values, regular physical activity and private living space) risk factors and investigated whether patients with adequate and limited participation differed in the number of risk factors. RESULTS: Almost one decade after treatment, two thirds of patients experienced educational and/or social difficulties. Patients with limited participation were more frequently associated with environmental factors such as low maternal education degree, siblings, main language other than German, discrepancies between societal and personal values and irregular physical activity, as well as the pathobiological risk factors treatment type, hydrocephalus, tumour relapse, cerebellar mutism and seizures. These variables significantly discriminated between patients with and without limited participation. CONCLUSIONS: Limited participation in patients treated for paediatric PFT is common. Next to pathobiological, also environmental risk factors play a major role in educational and social participation barriers. This highlights the fact that solely considering pathobiology is not sufficient when investigating risk factors for the emergence of late sequelae. Future aetiological studies must adopt a biopsychosocial perspective.

Evaluating the diagnostic validity of the cerebellar cognitive affective syndrome (CCAS) in pediatric posterior fossa tumor patients.

Background: The aim of this case-control study was to investigate the severity of the cerebellar cognitive affective syndrome (CCAS) in patients treated for pediatric posterior fossa tumors (PFT) and evaluate its diagnostic validity and predictive value for long-term effects. Methods: Using neuropsychological test data from 56 patients with PFT (average age: 14 years), the severity of deficits in the CCAS core areas (executive functions, verbal functions, visuospatial abilities and emotions/behaviour) was examined. Neuropsychological and academic long-term outcomes of patients with CCAS were compared to two control groups of PFT patients (treated with either surgery or surgery followed by radio-/chemotherapy) without the syndrome. Risk factors associated with various deficits were considered. Results: All but one PFT patient suffered from slight to severe impairments in at least one CCAS domain, while complete CCAS occurred in 35.7%. Seven years after tumor diagnosis CCAS patients performed worse in information processing, logical reasoning, verbal functions, visuospatial skills, and executive functioning and required more special educational support compared to the control groups. CCAS patients performed equally poor as patients treated with chemo-/radiotherapy in tasks measuring information processing speed. Risk factors were significantly associated with deficits in information processing speed but not CCAS emergence. Conclusions: Deficits in the core CCAS domains are commonly found in PFT patients, but varying in severity, which suggests the syndrome to be continuous rather than dichotomous. However, the validity of CCAS diagnosis was low and unspecific. The exclusion of relevant functions typically impaired in PFT patients (eg, information processing) resulted in difficulties being overlooked.

Impact of childhood cerebellar tumor surgery on cognition revealed by precuneus hyperconnectivity.

Background: Childhood cerebellar pilocytic astrocytomas harbor excellent overall survival rates after surgical resection, but the patients may exhibit specific cognitive and behavioral problems. Functional MRI has catalyzed insights into brain functional systems and has already been linked with the neuropsychological performance. We aimed to exploit the question of whether resting-state functional MRI can be used as a biomarker for the cognitive outcome assessment of these patients. Methods: We investigated 13 patients (median age 22.0 years; range 14.9-31.3) after a median interval between surgery and examination of 15.0 years (range 4.2-20.5) and 16 matched controls. All subjects underwent functional 3-Tesla MRI scans in a resting-state condition and battery neuropsychological tests. Results: Patients showed a significantly increased functional connectivity in the precuneus compared with controls (P < .05) and at the same time impairments in various domains of neuropsychological functioning such as a lower mean Wechsler Intelligenztest für Erwachsene (WIE) IQ percentile (mean [M] = 48.62, SD = 29.14), lower scores in the Trail Making Test (TMT) letter sequencing (M = 49.54, SD = 30.66), worse performance on the WIE subtest Digit Symbol Coding (M = 38.92, SD = 35.29), subtest Symbol Search (M = 40.75, SD = 35.28), and test battery for attentional performance (TAP) divided attention task (M = 783.92, SD = 73.20). Conclusion: Childhood cerebellar tumor treated by resection only strongly impacts the development of precuneus/posterior cingulate cortex functional connectivity. Functional MRI has the potential to help deciphering the pathophysiology of cerebellar-related cognitive impairments in these patients and could be an additional tool in their individual assessment and follow-up.

Awake brain surgery for language mapping in pediatric patients: a single-center experience.

OBJECTIVE: The goal of this study was to evaluate the feasibility, benefit, and safety of awake brain surgery (ABS) and intraoperative language mapping in children and adolescents with structural epilepsies. Whereas ABS is an established method to monitor language function in adults intraoperatively, reports of ABS in children are scarce. METHODS: A retrospective chart review of pediatric patients ≤ 18 years of age who underwent ABS and cortical language mapping for supratentorial tumors and nontumoral epileptogenic lesions between 2008 and 2019 was conducted. The authors evaluated the global intellectual and specific language performance by using detailed neuropsychological testing, the patient's intraoperative compliance, results of intraoperative language mapping assisted by electrocorticography (ECoG), and postsurgical language development and seizure outcomes. Descriptive statistics were used for this study, with a statistical significance of p < 0.05. RESULTS: Eleven children (7 boys) with a median age of 13 years (range 10-18 years) underwent ABS for a lesion in close vicinity to cortical language areas as defined by structural and functional MRI (left hemisphere in 9 children, right hemisphere in 2). Patients were neurologically intact but experiencing seizures; these were refractory to therapy in 9 patients. Compliance during the awake phase was high in 10 patients and low in 1 patient. Cortical mapping identified eloquent language areas in 6/10 (60%) patients and was concordant in 3/8 (37.5%), discordant in 3/8 (37.5%), and unclear in 2/8 (25%) patients compared to preoperative functional MRI. Stimulation-induced seizures occurred in 2 patients and could be interrupted easily. ECoG revealed that afterdischarge potentials (ADP) were involved in 5/9 (56%) patients with speech disturbances during stimulation. None of these patients harbored postoperative language dysfunction. Gross-total resection was achieved in 10/11 (91%) patients, and all were seizure free after a median follow-up of 4.3 years. Neuropsychological testing using the Wechsler Intelligence Scale for Children and the verbal learning and memory test showed an overall nonsignificant trend toward an immediate postoperative deterioration followed by an improvement to above preoperative levels after 1 year. CONCLUSIONS: ABS is a valuable technique in selected pediatric patients with lesions in language areas. An interdisciplinary approach, careful patient selection, extensive preoperative training of patients, and interpretation of intraoperative ADP are pivotal to a successful surgery.

Self-Care Strategies and Job Satisfaction in Pediatricians: What We Can Do to Prevent Burnout-Results of a Nationwide Survey.

Introduction: Working in the clinical field can be a demanding experience. While reports indicate escalating burnout rates among physicians, further investigation about what physicians can do to prevent burnout is necessary. Our objective was to assess self-care levels among pediatricians and the correlation with job satisfaction in order to subsequently identify protective factors. Methods: In this nationwide, cross-sectional study, a web-based survey was distributed to all Austrian pediatricians via a mailing list of the Austrian Society of Pediatrics. Self-care was measured with a modified Professional Self-Care Scale (PSCS), which consisted of nine items on a four-point Likert scale (from 1, "totally disagree," to 4, "totally agree"). Additional items addressed job satisfaction, peer support, and access to professional coaching. Results: The survey was distributed to 1,450 mailing list contacts, a total of 309 Austrian pediatricians completed the survey (21%). "Family" (M = 3.3) and "Friends" (M = 3.1) were the most highly rated self-care strategies. We found significant differences between pediatricians under 35 years and those aged 50 years and above (z = -4.21, p < 0.001). Peer support appeared to impact job satisfaction substantially. We found differences between pediatricians who frequently talk to colleagues about difficult situations, those who sometimes do so, and those who never do (p < 0.001), with a linear trend indicating increased job satisfaction with more frequent peer support (p < 0.001). Conclusions: Among all self-care strategies, a stable network of family and friends was highest rated, followed by balanced nutrition. Younger, male pediatricians working in hospital showed to be a vulnerable group with regard to overall self-care. Moreover, higher self-care values were found among those pediatricians who reported to receive peer support on a regular basis. We suggest combined organizational and individual interventions to promote pediatricians' well-being. Organizations should provide the possibility to select a well-balanced diet as well as space and time to consume food and cultivate a work environment that enables communication among peers and facilitates professional coaching. On the personal level, we want to encourage pediatricians to talk to trusted colleagues in challenging clinical situations and to consider working with a professional coach.

TIS - Talking in Symbols. Development of a Tool for Nonverbal Communication after Language Barriers in Pediatric Oncology.

Language barriers have been reported to have a detrimental effect on various outcomes in paediatric care, such as therapy adherence, and may even cause medical treatment errors. To address this issue, we developed a set of 63 cards with which a wide range of specific messages can be conveyed nonverbally in a clinical context. The conceptualization of the tool involved multiple phases. In Study 1, we held a workshop with 11 children and adolescents between 8 and 19 years that had received treatment for oncological conditions to gain an understanding of the specific challenges. In Study 2, we presented a first prototype to 3 children and 14 adults; participants were asked to rate the cards on multiple dimensions. Based on information from the previous trials, we developed a second prototype and asked 10 children and 7 adults to rate the cards on multiple dimensions. In this multidisciplinary approach in addition to our experts of clinical psychology we involved patient advocators and graphic designers in the process to achieve high feasibility and comprehensibility; based on the workshop, expert consensus surveys, data gathered in evaluation, all prototypes and the final card set were developed in close collaboration. Participants had little difficulty interpreting the cards and rated the information content as adequate. Importantly, a majority of participants indicated that they would keep using the tool during their stay at the hospital. Overall, the evaluation implied high acceptance and usability. The final card set is a promising communication tool in clinical paediatric settings with various language barriers. Further research should address how patient outcomes are impacted by using the tool.

Cerebellar pilocytic astrocytoma in childhood: Investigating the long-term impact of surgery on cognitive performance and functional outcome.

OBJECTIVE: Previous studies differ regarding the long-term effects of surgically removed pediatric cerebellar pilocytic astrocytomas (CPA). Thus, the aim of this study was to investigate the long-term impact on neurocognitive and functional outcome and to analyze age as an influencing factor. METHODS: Fourteen CPA patients were compared to the age norm and to a group of 14 high-achieving peers regarding cognitive functioning, health-related quality of life (HRQoL), and stress regulation. Mean follow-up time after diagnosis was 13.29 years (range: 3-21 years). RESULTS: Patients showed satisfactory academic achievement and did not differ from the norm except for the bodily dimension of HRQoL. However, there were marked differences in specific neurocognitive functions between patients and high achievers. Age at diagnosis did not influence neurocognitive outcome. CONCLUSION: CPA patients treated with surgery only seem to have a favorable long-term outcome, yet, in comparison with high achievers specific cognitive impairments become apparent.

From Symptom to Diagnosis-The Prediagnostic Symptomatic Interval of Pediatric Central Nervous System Tumors in Austria.

BACKGROUND: Children with central nervous system (CNS) tumours may present with a multitude of symptoms, ranging from elevated intracranial pressure to focal neurological deficit. In everyday practice, some signs may be misleading, thereby causing prolonged prediagnostic symptomatic intervals. Prediagnostic symptomatic intervals are longer for pediatric brain tumors than for other childhood malignancies. This study evaluated prediagnostic symptomatic intervals and parental and diagnostic intervals for pediatric patients with CNS tumours in Austria. It also considered socioeconomic factors. METHODS: Patients ≤ 19 years of age treated at the Medical University of Vienna and diagnosed during the years 2008 to 2013 were included. Patients diagnosed incidentally or by screening were excluded. RESULTS: Two hundred twelve consecutive patients were included in the study. They reflected the expected spectrum of CNS tumors. Patients presented with a median of five symptoms at diagnosis, most frequently with signs of elevated intracranial pressure. The median prediagnostic symptomatic interval was 60 days (0 days to seven years), the median parental interval was 30 days (0 days to 6.7 years), and the median diagnostic interval was three days (0 days to 6.5 years). In spinal tumors alone (n = 7), the median prediagnostic symptomatic interval was 70 days (ten days to seven years), and three of seven patients had a prediagnostic symptomatic interval longer than 320 days. Young age, higher tumor grade, and ataxia were associated with a shorter prediagnostic symptomatic interval. Localization in the supratentorial midline, histology of craniopharyngioma, and endocrine symptoms prolonged the prediagnostic symptomatic interval. There was a clear trend for longer prediagnostic symptomatic interval in non-native speakers. CONCLUSIONS: Results are comparable to other industrialized countries. However, long delays in diagnosis of central nervous system tumors still occur, urging increased awareness.

Do we still need IQ-scores? Misleading interpretations of neurocognitive outcome in pediatric patients with medulloblastoma: a retrospective study.

Over the past decades, many studies used global outcome measures like the IQ when reporting cognitive outcome of pediatric brain tumor patients, assuming that intelligence is a singular and homogeneous construct. In contrast, especially in clinical neuropsychology, the assessment and interpretation of distinct neurocognitive domains emerged as standard. By definition, the full scale IQ (FIQ) is a score attempting to measure intelligence. It is established by calculating the average performance of a number of subtests. Therefore, FIQ depends on the subtests that are used and the influence neurocognitive functions have on these performances. Consequently, the present study investigated the impact of neuropsychological domains on the singular "g-factor" concept and analysed the consequences for interpretation of clinical outcome. The sample consisted of 37 pediatric patients with medulloblastoma, assessed 0-3 years after diagnosis with the Wechsler Intelligence Scales. Information processing speed and visuomotor function were measured by the Trailmaking Test, Form A. Our findings indicate that FIQ was considerably impacted by processing speed and visuomotor coordination, which leaded to an underestimation of the general cognitive performance of many patients. One year after diagnosis, when patients showed the largest norm-deviation, this effect seemed to be at its peak. As already recommended in international guidelines, a comprehensive neuropsychological test battery is necessary to fully understand cognitive outcome. If IQ-tests are used, a detailed subtest analysis with respect to the impact of processing speed seems essential. Otherwise patients may be at risk for wrong decision making, especially in educational guidance.

Neuronal correlates of cognitive function in patients with childhood cerebellar tumor lesions.

While it has been shown that cerebellar tumor lesions have an impact on cognitive functions, the extent to which they shape distant neuronal pathways is still largely undescribed. Thus, the present neuroimaging study was designed to investigate different aspects of cognitive function and their neuronal correlates in patients after childhood cerebellar tumor surgery. An alertness task, a working memory task and an incompatibility task were performed by 11 patients after childhood cerebellar tumor surgery and 17 healthy controls. Neuronal correlates as reflected by alterations in functional networks during tasks were assessed using group independent component analysis. We were able to identify eight networks involved during task performance: default mode network, precuneus, anterior salience network, executive control network, visual network, auditory and sensorimotor network and a cerebellar network. For the most 'basic' cognitive tasks, a weaker task-modulation of default mode network, left executive control network and the cerebellar network was observed in patients compared to controls. Results for higher-order tasks are in line with a partial restoration of networks responsible for higher-order task execution. Our results provide tentative evidence that the synchronicity of brain activity in patients was at least partially restored in the course of neuroplastic reorganization, particularly for networks related to higher-order cognitive processes. The complex activation patterns underline the importance of testing several cognitive functions to assess the specificity of cognitive deficits and neuronal reorganization processes after brain lesions.

Applying the International Classification of Functioning-Children and Youth Version to Pediatric Neuro-oncology.

Given the increased survival rates in patients with pediatric central nervous system tumors, late effects such as treatment- and/or illness-related neurologic sequelae as well as neuropsychological deficits and social difficulties have moved into focus in follow-up care. In order to provide personalized treatment recommendations for pediatric brain tumor survivors, it is crucial not only to assess cognitive impairments but also to measure a patient's functional deficiencies, for example, restricted participation in everyday social activities. Thus, this article introduces the International Classification of Functioning-Children and Youth version (ICF-CY) as a conceptual framework for quantifying functional limitations and informing long-term care in pediatric neuro-oncology. A standardized self-report and proxy-report questionnaire for measuring participation is briefly discussed and specific recommendations based on so-called core sets for clinical practice in pediatric neuro-oncology are provided.

Strategies to improve the quality of survival for childhood brain tumour survivors.

BACKGROUND: Tumours of the central nervous system (CNS) are the most frequent solid tumours and the second most frequent type of cancer in children and adolescents. Overall survival has continuously improved in Germany, since an increasing number of patients have been treated according to standardised, multicentre, multimodal treatment recommendations, trials of the German Paediatric Brain Tumour Consortium (HIT-Network) or the International Society of Paediatric Oncology-Europe (SIOP-E) during the last decades. Today, two out of three patients survive. At least 8000 long-term childhood brain tumour survivors (CBTS) are currently living in Germany. They face lifelong disease- and treatment-related late effects (LE) and associated socioeconomic problems more than many other childhood cancer survivors (CCS). METHOD: We review the LE and resulting special needs of this particular group of CCS. RESULTS: Despite their increasing relevance for future treatment optimisation, neither the diversity of chronic and cumulative LE nor their pertinent risk factors and subsequent impact on quality of survival have yet been comprehensively addressed for CBTS treated according to HIT- or SIOP-E-protocols. Evidence-based information to empower survivors and stakeholders, as well as medical expertise to manage their individual health care, psychosocial and educational/vocational needs must still be generated and established. CONCLUSION: The establishment of a long-term research- and care network in Germany shall contribute to a European platform, that aims at optimising CBTSs' transition into adulthood as resilient individuals with high quality of survival including optimal levels of activity, participation and acceptance by society.
