Targeted therapy with anlotinib for a H3K27M mutation diffuse middle glioma patient with PDGFR-α mutation: a case report.

H3K27M-mutant diffuse midline glioma (H3K27M-mt DMG) was a novel entity, which was defined by K27M mutations in H3F3A or HIST1H3B/C in the 2016 WHO updated fourth edition of the central nervous system (CNS) tumor classification. There is an urgent need for effective therapeutic strategies. Anlotinib is a multitarget tyrosine kinase inhibitor, which has not been reported for H3K27M-mt DMG treatment. Here, we firstly reported an adult multifocal H3K27M-mt DMG patient benefiting from anlotinib. This report provides a promising treatment option for H3K27M-mt DMG patients.
