Brief Summary
Recent experiments are giving researchers insight into the changes (mutations) that occur in an individual brain tumor cell compared to a normal cell. Currently, we do not have enough knowledge about how uniform these changes are throughout a single brain tumor and if different regions of a brain tumor have different groupings of changes. By obtaining multiple samples of the tumor from various regions during surgery, it will allow researchers to better understand these changes, with the hope that they will lead to new discoveries in the diagnosis and treatment of brain tumors.

Outcome Measures
Primary Outcomes (1)
Feasibility, as measured by percentage of the sample deemed viable by flow cytometry
Flow cytometry will be performed to quantify viable cells in a cell suspension. This will be reported as a percentage of live cells of the population
1 year
Other Outcomes (3)
Number of somatic mutations per region
1 year
Gene expression in tumor regions
1 year
DNA methylation status in tumor regions
1 year
Study Arms (1)
Tissue Preservation System (TPS)
EXPERIMENTALTumor tissue will be obtained, processed, and then transported remotely to undergo multiple tests, including gene panel DNA sequencing, DNA methylation array, and bulk as well as single-cell transcriptome analyses (RNA-seq)
Interventions
Tumor tissue will be obtained by the NICO Myriad and Tissue Preservation System (TPS) via an automated, standardized methodology
Eligibility Criteria
You may qualify if:
- Participants who have the appearance of high grade glioma on MR imaging are allowed to consent and will undergo the procedure if the frozen is consistent with World Health Organization Grade IV glioma (glioblastoma or gliosarcoma) OR
- Participants with a history of histologically-confirmed diagnosis of World Health Organization Grade IV glioma (glioblastoma or gliosarcoma) that are undergoing repeat resection of a recurrent tumor as identified on preoperative MR imaging
- Contrast-enhancing tumor volume of at least 15 cc on the preoperative, volumetric MRI within 1 month prior to surgery
- Karnofsky performance status of 70 or higher
- The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
- Screening/Baseline laboratory values must meet the following criteria within 1 month prior to surgery:
- Hematological
- Absolute neutrophil count (ANC): ≥ 1500/µL
- Platelets ≥100 000/µL
- Hemoglobin ≥ 9.0 g/dL or ≥5.6 mmol/L ----Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.
- Renal
- Creatinine OR Measured or calculated creatinine clearance (glomerular filtration rate (GFR) can also be used in place of creatinine or CrCl) ≤ 1.5 × ULN OR ≥30 mL/min for participant with creatinine levels \>1.5 × institutional ULN
- Creatinine clearance (CrCl) should be calculated per institutional standard.
- Coagulation
- International normalized ratio (INR) OR prothrombin time (PT). Activated partial thromboplastin time (aPTT) ≤ 1.5 × upper limit of normal (ULN) unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
- +2 more criteria
You may not qualify if:
- Has a history or current evidence of any medical condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
- Is pregnant.
