GroupInterventionDescription
Cohort ALumber PunctureCohort A will consist of newly diagnosed patients with Glioblastoma. Eligibility for enrollment prior to pathology diagnosis will be determined by a consensus diagnosis of high grade glioma based on clinical and radiographic evidence between neuroradiologist, neurosurgeon and study PI.
Cohort BLumber PunctureCohort B will consist of patients with a histologically confirmed diagnosis of IDH WT glioblastoma.

Overall Survival6 months

Overall survival will be calculated as the time from pathological diagnosis to the date of death due to any cause (prior to analysis cut-off) or last follow-up
