cimpact-4

Pediatric low-grade gliomas were shown to be characterized by an array of distinct molecular aberrations. The cIMPACT-4 consensus proposed pediatric low-grade gliomas of the diffuse type to be characterized by distinct molecular changes rather than distinct histological features.

Fukuoka et al. described a small series of pediatric oligodendroglioma-like tumors with BRAF V600E mutations. Interestingly, they exhibited molecular changes usually associated with adult high-grade gliomas: chromosome instability, chromosome 7 gains, and chromosome 10 loss, but had an indolent natural history 1).
