Context: Treatment of Pediatric-Type Diffuse High-Grade Gliomas
Children with inheritable biallelic mismatch repair deficiency have a very high mutational burden and neoantigen expression. These patients are at risk of developing a variety of cancers, including hematologic malignancies, gastrointestinal cancers, and high-grade gliomas. The high variant and neoantigen load have been associated with responsiveness to immune checkpoint inhibition. Early case reports have demonstrated clinical imaging responses in children who are treated with an anti-programmed death-1 inhibitor.[48]
