Brief summary

Patients with 1p/19q-codeleted anaplastic gliomas treated with RT + PCV are at risk of neurocognitive deterioration. Treating these patients with PCV alone (could reduce the risk of neurocognitive deterioration without impairing overall survival.

Detailed description

Multicentric, Randomized phase III study (1:1), Population: newly diagnosed 1p/19-codeleted anaplastic gliomas, Primary objective: To determine whether treating newly diagnosed 1p/19q-codeleted anaplastic gliomas with PCV alone can increase overall survival without neurocognitive deterioration Control group: radiotherapy followed by 6 cycles of PCV chemotherapy. Experimental group: 6 cycles of PCV chemotherapy (radiotherapy being deferred at the time of progression). Number of centres participating: the 33 centers of the POLA network Recruitment duration: 7 years, the accrual rate being 40 patients per year, and patients are followed-up until the end of the trial.

Interventions

DRUGPCV chemotherapy alone

PCV cycles are 6 weeks long PCV chemotherapy is given as: Day 1: CCNU 110 mg/m2 orally; Days 8 and 29: vincristine 1.4 mg/m2 IV; Days 8 to 21: procarbazine 60 mg/m2 orally
