Glioma : Oligodendroglioma or Astrocytoma

The precise positioning of the emerging group of pharmacological inhibitors of mutant IDH enzymes remains to be refined by further studies and defined in national and international guidelines. The present study shall help to close this important knowledge gap when trying to define the role of mutant IDH inhibitors in the treatment algorithms for patients with IDH-mutant WHO grade 3 gliomas. Safusidenib is a novel, oral, potent, brain penetrant inhibitor of mutant IDH1. It has shown high blood brain barrier penetration in both pre-clinical and clinical studies and demonstrated anti-tumor activity with complete or partial responses. We aim at demonstrating the efficacy of safusidenib in patients with newly diagnosed IDH1-mutant CNS WHO grade 3 oligodendroglioma and astrocytoma, measured by progression-free survival at12 months.

A vision-language model using preoperative MRI and clinical variables has been developed to simultaneously predict three key molecular markers in midline gliomas: H3K27M, IDH, and 1p/19q. This prospective multicenter study will validate the model's accuracy in preoperative molecular subtyping and its value in prognostic assessment and clinical decision-making across multiple neurosurgical centers.
