title: [The prognostic role of Ki-67 in childhood low-grade glioma].
abstract: Gliomas currently represent a group of uncommon diseases originating from glial elements. According to their biologic features they can be distinguished in low-grade gliomas--not very aggressive and with a poor tendency to progression--and high-grade gliomas--with a greater proliferative drive and aggressiveness. Such definitions outline two distinct disease types, which profoundly differ as for epidemiological, clinical, diagnostic and molecular features. The introduction of biomolecular techniques has provided a deeper knowledge of low-grade gliomas: the use of new molecular markers, such as Ki-67, makes it possible to study peculiar features of the neoplasm, with strong prognostic implications. Nonetheless, in the literature there is still no agreement on their role, nor on their prognostic validity in pediatric age, also because the criteria that are currently used for adult patients haven't still been codified for pediatric age.
