Outcomes
Primary outcome [1] 3105 0
Progression Free Survival (PFS) - PFS is the time interval between the date of randomization and the date of disease progression or death, whichever comes first. If neither event has been observed, then the patient is censored at the date of the last follow up examination.

Summary
Brief summary
A randomized study to demonstrate a difference in progression-free survival (PFS) for primary treatment with temozolomide in order to assess: whether PFS and OS can be prolonged by primary chemotherapy with
temozolomide, whether the incidence of late toxicity can be decreased by using primary chemotherapy, the toxicity profile of the two treatments and the quality of life of the patients
The impact of 1p deletions in low-grade gliomas: prognostic effect of tumors with deletion on PFS overall and by treatment group. Benefit for patients with LGGs and deletions treated with TMZ compared to
radiotherapy alone with respect to survival. Interaction between treatment and cytogenetic features.
