Neurosurgical and neuro-oncological outcomes of confirmatory brain biopsies in patients with glioblastoma: a real-life monocentric experience.

Unmethylated MGMT status, KPS≤70, tumor proximity to the internal capsule and absence of motor hemisyndrome at symptoms onset emerged as possible risk factors.

Biopsied glioblastoma patients had an 11% complication rate and exhibited a dismal short-term prognosis, with a median survival of 4.7 months.
