The role of frameless stereotactic biopsy in contemporary neuro-oncology: molecular specifications and diagnostic yield in biopsied glioma patients.

A formally complete diagnosis according to 2016 CNS WHO was achieved in the majority of cases. The biopsy cohort showed a prognostically unfavorable distribution of diagnoses and molecular features. Frameless stereotactic biopsy seems to be confirmed as a useful diagnostic tool in contemporary neuro-oncology-however, certain potential limitations should be considered.
