SURG-30. CLINICAL COURSE OF IDH-MUTATED LOW-GRADE GLIOMAS DURING THE POSTSURGICAL ACTIVE MONITORING PHASE: ASYMPTOMATIC PATIENTS, WELL CONTROLLED SEIZURES, BUT CONTINUOUS GROWTH OF TUMOR RESIDUES

INTRODUCTION Postponing adjuvant treatment after resection in IDH-mutated low-grade glioma (LGG) seems appropriate in selected patients. Here we describe the clinical course of these patients during post-resection active monitoring with MRI scans, as literature on this topic is scarce. METHODS We included IDH-mutated LGG patients that underwent surgery between 2003–2016, with clinical follow-up including MR scans available. Samples were...
