In the last decades, many advances have been made in the field of genetic abnormalities of glial and glioneuronal brain tumors. In the 2016 World Health organization (WHO) Classification of Tumors of the Central Nervous System, the concept of "integrated" diagnosis emerged: histological and genetic/molecular features now define many entities. Since 2016, six updates have been published by the c-IMPACT-NOW (the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy- Not Official WHO) to develop and clarify the "integrated" diagnosis. In the future WHO 2021 Classification of Tumors of the Central Nervous System, "integrated" diagnoses will take up even more importance. Even if they can have similar histological features, gliomas of children are very different from the "adult" gliomas in the molecular mechanism of oncogenesis. The histomolecular features of adolescents/young adults (AYAs) can have similarities with "pediatric-type" or "adult-type" gliomas, but few studies have focused specifically on the histomolecular profiles of gliomas in AYAs. The investigators would like to study the cohort of patients treated for a glial and glioneuronal tumor diagnosed under the age of 25 in the Amiens University Hospital between 2008 and 2020. The investigators would like to compare the histomolecular profiles of gliomas in children (0-14 years) and AYAs (15-25 years).

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT04916015 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
