IDH Mutant Lower-Grade Gliomas

The goal of this observational study is to better define the molecular profile of rare brain tumors (gliomas) based on the levels of their metabolites and transcripts (the intermediate step between DNA information and proteins). The main question it aims to answer is to identify new brain tumour subgroups of clinical relevance that might explain the very different history these patients might follow. Additionally, studies on gliomas require cellular cultures and animal models for the development of new medications, but these models are still scarce and rudimental for many types of gliomas. The second aim of this study is to implement better models for these tumors, for a more effective development of new medications. Patients enrolled in this study will not undergo any additional procedures with respect to those necessary for gold-standard management of these brain tumors. A small sample of the resected tumour will be used for advanced analyses investigating the metabolic and transcriptomic profile and used for temptative establishment of cellular cultures and animal models of these pathologies.
