| Sumario: | In 2016 WHO classification of CNS tumors genotypic and phenotypic parameters were integrated to define a new nomenclature of diffuse gliomas on the basis of presence or absence of isocitrate dehydrogenase mutations. This resulted in more homogenous and narrowly defined categories with better accuracy of prognostic information, thus, playing a crucial role in patient management. Broadly, astrocytomas are now histologically and genetically distinct with IDH-mutant, ATRX-mutant, 1p/19q-intact and oligodendroglial tumors has IDH-mutant, ATRX-wildtype and 1p/19q-codeleted profile. Glioblastoma are now classified into primary and secondary on the basis of IDH mutations independent of clinical history. |
