Lay Summary The Pediatric Brain Tumor Consortium Study, PBTC-N13, sampled 100 archived patient samples from four different pediatric, malignant brain tumor categories. Each sampled was tested for PD-1 and PD-L1 expression and then had more extensive immune profiling. This enables learning how the immune landscape differs among tumors in order to better understand the potential for individual tumor immune profiling to be considered in patient-directed care.
