Summary
Patients with glioblastoma face a grim prognosis. Despite recent advancement in neurosurgical technology and neuro-oncology glioblastomas almost invariably progress or recur after a median of 4-8 months. The strategy to repeat tumor resection at recurrence in order to minimize tumor load and thus to facilitate subsequent second-line therapy has been shown to be feasible and safe. However, evidence for a survival benefit of surgery for recurrent glioblastoma is scarce and relies entirely on retrospective analyses. While most retrospective analyses report an apparent survival benefit, an EORTC meta-analysis on second-line therapies found no survival difference in patients with or without surgery at recurrence. With regard to the risks and costs inherent to surgery for glioblastoma, a randomized controlled trial is required. The purpose of the study is to compare the effect of craniotomy and tumor resection followed by adjuvant second-line therapy to no surgery followed by second-line therapy on overall survival, neurological status, and quality of life. Analysis of overall survival will be used to improve sample size estimation of a subsequent phase III trial for craniotomy and tumor resection of glioblastoma recurrence in cooperation with the EORTC.

Interventions
Surgery: Surgery must take place between day 1 and 14 after study inclusion and within 21 days from the MRI on which recurrence was diagnosed. The modalities of surgery and the choice of pre- and intra-operative technical adjuncts is at the treating neurosurgery discretion. Surgery must take place between day 1 and 14 after study inclusion and within 21 days from the MRI on which recurrence was diagnosed. The modalities of surgery and the choice of pre- and intra-operative technical adjuncts is at the treating neurosurgery discretion. However, some form of intra-operative resection control (iMRI or intra-operative fluorescence) and function control (electrophysiology) should be available to the surgeon and used when warranted. Adjuvant second-line therapy: Patients will be seen after surgery by the treating neurooncologist. Modalities of adjuvant second-line therapy are individually defined according to local guidelines and are not stipulated by study protocol.
Patients randomized to the non-surgical cohort receive second-line therapy according to local guidelines. Modalities thereof are not stipulated by study protocol.
