Exclusion criteria
Exclusion criteria: •Progressive or recurrent glioblastoma documented by MRI earlier than 180 days after first surgery for glioblastoma and earlier than 90 days after completion of radiotherapy. •Any other prior treatment than temozolomide according to the schedule of the EORTC NCIC trial (Stupp et al.

| Main Objective: The aim of this study is to compare two regimens of dose-intensified temozolomide chemotherapy for patients with glioblastoma at first relapse or progression who have failed first-line treatment with radiotherapy plus concomitant or adjuvant temozolomide or both. Primary objective: Median time to treatment failure. Treatment failure is reached (i) upon tumor progression (ii) if treatment has to be terminated due to toxicity or (iii) if the patient dies for any reason. ;Secondary Objective: •PFS •Overall survival •Objective responses (CR and PR) •Outcome relative to MGMT promoter methylation in recurrent tumor •Outcome relative to duration of prior treatment •Outcome relative to interval from completion of prior TMZ chemotherapy treatment ( 3 months) •Toxicity •Expression of the mismatch repair genes MLH-1, MSH-2, MSH-6 und PMS2 in tumor tissue determined by immunohistochemistry •Changes in MGMT status in recurrent disease relative to initial tumor tissue if applicable •Changes in MGMT activity in peripheral blood during ongoing therapy will be assessed during the first cycle at days 1, 8, 15, 22, then MGMT activity will be investigated every 8 weeks •Quality of life determined by EORTC QoL-Brain 20 Neurotoxicity determined by MRI •Neurotoxicity determined by MMSE, MRI and NeuroCogFx neuropsychological examination •Outome relative to extent of resection •Screening for aberrant MGMT promoter methylation in peripheral blood ;Primary end point(s): Median time to treatment failure. Treatment failure is reached (i) upon tumor progression (ii) if treatment has to be terminated due to toxicity or (iii) if the patient dies for any reason. | — |
