The brain is also one of the most sensitive organs to treatments used in pediatric oncology, even for cancers not related to the central nervous system. Therapeutic index is therefore a major issue in pediatric neuro-oncology. The efficacy of the therapy as well as its toxicity are difficult to measure using standard tests. In order to optimize therapies that could have an impact on the brain, and consequently on the quality of life of patients, it becomes crucial to optimize the means of evaluation.\n\nFew studies to date have focused on the various components of memory impacted following treatment of a posterior fossa tumour. However, supra-tentorial structures such as the hippocampus, which have long been described for their role in memory, are either partially irradiated (irradiated in their lower part due to their proximity to the target volume during irradiation of the posterior fossa) or completely irradiated (e.g. included in the prophylactic irradiation of medulloblastoma prior to dose supplementation in the posterior fossa). On the other hand, the cerebellum plays a central role in learning and procedural memory involved in motor and cognitive learning, as it enables automation and procedural retention such as reading (automation of the grapho-phonemic conversion procedure) or arithmetic (mental arithmetic).\n\nIMPALA study is aimed at investigating the impact of different irradiation doses received by children treated with radiotherapy on cognitive functions related to the hippocampus and to the cerebellum.\n\nThis exploratory study will thus provide elements enabling a better limitation of radiotherapy doses on regions linked to the development of cognition and memory. The project brings together researchers and clinicians with complementary expertise in oncology, neurology and imaging in both children and adults. This study will also provide a better understanding of the role of the cerebellum in memory and executive functions, and develop a method that can then be used in a prospective longitudinal multicentre form.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nFOR ALL PARTICIPANTS\n\n* Affiliation to or beneficiary of a social security scheme\n* French mother tongue\n* Sufficient visual, auditory (hearing aids permitted), speaking and writing skills for proper performance of neuropsychological tests\n* Written informed consent of the adult participant, or of the representatives of parental authority, if applicable\n\nFOR IRRADIATED PATIENTS\n\n* Patient treated before 18 years old\n* Patient considered cured after irradiation of a brain tumour (complete clinical and iconographic response at 5 years after the end of radiotherapy).\n* Patient who has received localized brain irradiation or craniospinal irradiation for a brain tumour whose treatment includes first-line radiotherapy (ependymomas, medulloblastomas, malignant germinal tumours)\n* Patient who received 54 or 59.4 Gy in a localized part of the posterior fossa or supra-tentorial brain; or patients who received 54 Gy over all or part of the posterior fossa and prophylactic irradiation of the entire brain\n\nFOR PATIENTS TREATED BY SURGERY AND/OR CHEMOTHERAPY\n\n* Patients resected from a posterior fossa tumour without radiotherapy (i.e., brain tumours whose treatment does not include first-line radiotherapy: low-grade gliomas including pilocytic astrocytomas)\n* Patient treated before 18 years old\n* Patient considered cured at 5 years after the end of treatment\n\nExclusion Criteria:\n\nFOR ALL PARTICIPANTS\n\n* Individual under legal protection of adults (judicial safeguard, guardianship, curatorship, institutionalized, or under a mandate for future protection)\n* Severe ataxia\n* Individual who participated in another research study that included treatment within the previous 3 years\n* Individual with a contraindication to MRI (i.e. in particular, cardiac pacemaker or defibrillator carriers, implanted equipment activated by an electrical, magnetic or mechanical system, carriers of haemostatic clips on intracerebral aneurysms, carriers of orthopaedic implants, claustrophobic)\n\nFOR HEALTHY VOLUNTEERS\n\n* Known neurological or psychiatric history\n* History of learning disability or neurodevelopmental disorder follow-up\n* Patients undergoing psychotropic treatment (methylphenidate, antidepressants, etc.).'}, 'identificationModule': {'nctId': 'NCT04324450', 'acronym': 'IMPALA', 'briefTitle': 'Memory Neuroimaging in Children, Adolescents and Young Adults Following Pediatric Cancer', 'organization': {'class': 'OTHER_GOV', 'fullName': 'Institut National de la Santé Et de la Recherche Médicale, France'}, 'officialTitle': 'Memory Neuroimaging in Children, Adolescents and Young Adults Following Pediatric Cancer', 'orgStudyIdInfo': {'id': 'C19-17'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Patients radiotherapy +', 'description': 'Patients cured of a brain tumour and who have received radiotherapy in childhood', 'interventionNames': ['Device: MRI', 'Behavioral: Cognitive assessment']}, {'type': 'EXPERIMENTAL', 'label': 'Patients radiotherapy -', 'description': 'Patients cured of a brain tumour and who have received surgery and/or chemotherapy but were not irradiated', 'interventionNames': ['Device: MRI', 'Behavioral: Cognitive assessment']}, {'type': 'EXPERIMENTAL', 'label': 'Healthy volunteers', 'description': 'Healthy volunteers (control group) matched in age, manual laterality, gender and parental education to "Patients radiotherapy +"', 'interventionNames': ['Device: MRI', 'Behavioral: Cognitive assessment']}], 'interventions': [{'name': 'MRI', 'type': 'DEVICE', 'description': 'The MRI protocol is composed of:\n\n* T1-weighted anatomical sequences\n* DTI sequences\n* resting functional MRI\n* 3D MR spectroscopic imaging', 'armGroupLabels': ['Healthy volunteers', 'Patients radiotherapy +', 'Patients radiotherapy -']}, {'name': 'Cognitive assessment', 'type': 'BEHAVIORAL', 'description': 'Battery of neuropsychological tests', 'armGroupLabels': ['Healthy volunteers', 'Patients radiotherapy +', 'Patients radiotherapy -']}]}, 'contactsLocationsModule': {'locations': [{'zip': '31024', 'city': 'Toulouse', 'country': 'France', 'facility': 'ToNIC / UMR1214', 'geoPoint': {'lat': 43.60426, 'lon': 1.44367}}], 'overallOfficials': [{'name': 'Anne LAPRIE', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'ToNIC / UMR1214'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Institut National de la Santé Et de la Recherche Médicale, France', 'class': 'OTHER_GOV'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
