On 22 July, most of the authorship group of COGNO’s Expert Position Statement on the management of adults with IDH-mutant gliomas will come together for a two-hour case-based webinar, working through three clinical scenarios spanning grade 2 to grade 4 disease. The cases cover the questions that generate the most debate in practice: when to treat versus watch, the role of vorasidenib after resection, PCV versus temozolomide in oligodendroglioma, and the Stupp versus CATNON approach in grade 4 astrocytoma. Emerging trials including VIGOR, SIGMA, and LUMOS-2 will also be discussed.
