Supramarginal Resection in Glioblastoma
Glioblastoma
About this trial
This is an interventional treatment trial for Glioblastoma focused on measuring Neurosurgical procedures
Eligibility Criteria
Inclusion Criteria:
- A suspected diagnosis of supratentorial glioblastoma by MRI.(A)
- Indication for surgical treatment and where supramarginal resection is considered possible according to the preoperative imaging. This consideration needs to be verified by two specialists in neurosurgery.
- Negative work-up for other primary tumor(B)
- Karnofsky performance status of 70 - 100.
A) If randomized to supramarginal surgery, intraoperative frozen section must conclude with "high-grade glioma" to be able to proceed. Surgery in two sessions is also possible in supramarginal group if there is no intraoperative frozen section available or frozen section indicate another diagnosis, but final histopathology reveals a glioblastoma. In case of surgery in two session, there must be no more than 30 days between procedures. See flow-chart in attachment 1.
B) No suspected primary tumor seen on CT chest, abdomen and pelvis. If relevant symptoms/clinical suspicion also supplement with mammography, dermatologist exam, relevant endoscopies etc.
Exclusion Criteria:
- Not willing to be randomized.
- Informed consent not possible (e.g. language barriers, aphasia, cognitive severely impaired).
- Contrast enhancement volume bilateral OR involving corpus callosum.
- Contrast enhancement along the ependymal lining of ventricles (contact is however not an exclusion criteria).
- Contrast enhancement involving several lobes.
- History of major psychiatric disorder such as psychosis, schizophrenia and/or mood disorder (e.g. depression and bipolar disorder) in need of hospitalization
- Unfit for participation for any other reason judged by the including physician

Arms of the Study
Arm 1
Arm 2
Active Comparator
Experimental
Conventional surgery
Supramarginal surgery
Aim of gross total resection (i.e. removal of contrast enhancing tumor) according to institutional practice. No limit in use of technical adjuncts in this arm.
Aim of supramarginal resection, where a margin of at least 10 mm is considered feasible prior to surgery. The resection is guided by the T2 volume (i.e. zone of edema) where removal of as much as possible of this zone (or beyond) is attempted as long as considered safe
