About this trial
Because of their prolonged survival, patients with 1p/19q-codeleted low-grade oligodendrogliomas treated with RT + PCV are at risk of neurocognitive deterioration. We make the hypothesis that withholding radiotherapy until tumor progression could reduce the risk of neurocognitive deterioration without impairing overall survival.
Eligibility criteria
Qualifiers
Tumor is co-deleted for 1p and 19q based and IDH-mutant (IDH1 or IDH2) according to local diagnosis

Age ≥ 18 years
Patients with one or several prior surgical procedure for a low-grade oligodendroglioma and who undergo a resurgery are eligible if they have not received prior radiotheray or chemotherapy and if the last histological diagnosis is a low-grade oligodendroglioma prior use of specific HDI prohibitions is permitted
