Eligibility Criteria

Age 18+ · All Participants · 10 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
To be eligible for the study, patients must submit at least 1 block of tumor tissue
The patient has a histologically proven diagnosis of glioblastoma (WHO grade IV) that has been confirmed by a central review
will be collected and snap frozen Tumor tissue that is found to have enough quantity for analysis of O6-methylguanin-DNA-methyltransferase (MGMT) status will be collected and frozen.
Within 28 days prior to step 2 registration, the individual must have a history/physical examination.
Prior to Step 1 Registration, you will need to complete the following: 1
A contrast-enhanced MRI of the brain must be performed postoperatively within 72 hours of surgery; if the tumor is 5 cm or less in diameter, the patient is eligible for the trial.
The GBM tumor must be located in the top part of the brain only
and prior to any study-related procedures
