Preoperative Radiosurgery in High Grade Glioma: A Phase I Clinical Trial: The NeoGlioma Study
This phase I trial finds out the possible benefits and/or side effects of radiosurgery before surgery (preoperative) in treating patients with high grade glioma. Radiosurgery uses special equipment to position the patient and precisely give a single large dose of radiation to the tumor. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving pre-operative radiosurgery may improve the odds of brain tumor control and reduce treatment-related side effects.
• Age \>= 18 years
• Clear clinical and radiographic evidence of primary high grade glioma (HGG) as judged by the Mayo multidisciplinary neuro-oncology team (World Health Organization \[WHO\] grade III-IV, including glioblastoma) regardless of IDH and MGMT status
• Patients who underwent a previous biopsy confirming high grade glioma are eligible for enrollment
• Planned neurosurgical resection of tumor
• Judged to not be at risk of significant clinical risk (i.e. herniation) with radiation-induced edema prior to resection
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2
• Negative pregnancy test done =\< 14 days prior to registration, for women of childbearing potential only. Patients over 50 years of age who decline pregnancy testing are still eligible without a pregnancy test.
• Ability to complete questionnaire(s) by themselves or with assistance

• Willing to receive adjuvant radiotherapy at enrolling institution at the time of registration
• Willing to provide tissue and/or blood samples for correlative research purposes
