Glioma Malignant Glioma Recurrent Glioma Recurrent Malignant Glioma | Procedure: Biospecimen Collection Procedure: Diagnostic Imaging Procedure: Magnetic Resonance Imaging | Early Phase 1 |
PRIMARY OBJECTIVES:
I. Construct and test a novel multinuclear Na+-H+ metabolic MRI sequence with sensitivity to Sodium (Na+) concentration, Potential of Hydrogen (pH), and oxygen (O2).
II. Correlate Na+-, pH-, and O2-weighted MR image measurements with sodium-proton exchanger isoform-1 (NHE1) immunohistochemistry (IHC), bioenergetics, and gene expression using stereotactic image-guided biopsies from human brain tumors.
III. Quantify changes in Na+-, pH-, and O2-weighted MR images after neoadjuvant anti-PD-1 immunotherapy in recurrent glioblastoma (GBM) and explore associated changes in tumor biology.
OUTLINE:
AIM 1: Previous scan data from healthy subjects is collected and analyzed.
AIM 2: Patients undergo MRI. Patients also undergo collection of tissue samples for IHC analysis.
AIM 3: Patients undergo multinuclear metabolic imaging before and after immunotherapy and prior to surgical resection.

- Total sodium concentration [ Time Frame: Up to 5 years ]Will calculate NaT using standard methodology and normalize it to ocular Na+ concentration, a constant 135 mmol/l. Will then test whether healthy tissue has a coefficient of variance (COV) of < 10% across all 20 subjects.
- NHE1 expression [ Time Frame: Up to 5 years ]Will create a comprehensive map of genes/pathways and unique cell subsets associated with NHE1 expression.
- Tumor metabolism [ Time Frame: Up to 5 years ]Will examine the correlation between baseline tumor metabolism and change in metabolism with respect to overall survival using Cox multivariable regression.
