About this study

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.
