Regional reproducibility of immune expression programs in glioblastoma and implications for single-biopsy assessment
Tissue immune measurements can guide immunotherapy only if one biopsy represents the rest of the tumor. We quantified this in a secondary analysis of public data from 75 magnetic resonance imaging (MRI)-localized glioblastoma (GBM) biopsies from 19 patients. Fourteen transcriptomic modules scored supportive, inhibitory, and checkpoint programs. The intraclass correlation coefficient (ICC) gave…
