Life expectancy in glioblastoma patients who had undergone stereotactic biopsy: a retrospective single-center study.

Diagnostic and surgical advances related to GBM treatment mean that radical resections can be performed even in eloquent brain areas. However, patients not indicated for resection will experience a major reduction in life expectancy. Patients who underwent stereotactic biopsy and received some form of oncological treatment experienced slightly increased overall survival relative to patients with a natural disease course. Patients with favorable clinical factors reacted better to treatment.
