About this study

This pilot research trial studies blood brain barrier differences in patients with brain tumors undergoing surgery. Studying samples of tissue and blood from patients with brain tumors in the laboratory may help doctors to understand how well drugs get into different parts of a brain tumor. This may help them to determine which types of drugs may be best for treating brain tumors.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria:

  • Clinical and radiographic evidence suggesting CNS malignancy
  • Suspected newly diagnosed, local, or intracranial recurrence of primary brain tumor OR previously untreated or treated brain metastasis
  • Willing to undergo a neurosurgical resection of CNS lesion at Mayo Clinic Rochester
  • Able to have magnetic resonance imaging (MRI) imaging with gadolinium contrast (e.g. no cardiac pacemaker, defibrillator, renal failure)
  • Provide written informed consent
  • Willing to provide tissue and blood samples for research purposes

Exclusion Criteria:

  • Vulnerable populations: pregnant women, prisoners, mentally handicapped
  • Unable to undergo a biopsy of CNS lesion
  • Documented drug allergy to cefazolin or levetiracetam, or other contraindication to use these drugs in the pre-operative setting (e.g., patient is already on another anti-seizure medication which precludes the clinical indication for pre-operative levetiracetam)
