Background: The 2016 WHO classification of CNS tumors included molecular parameters in addition to histology to redefine many tumor entities. Low-grade glioma (LGG) are divided into isocitrate dehydrogenase (IDH) wild type or mutant. Absence of IDH mutation is a rare event in LGG, and IDH wild type are considered a provisional entity. The technique used to assess IDH mutation is essential to determine the real impact of this tumor type. Methods: The observation of a particularly favorable outcome in a group of 42 patients with a diagnosis of IDH wild type LGG (OS= 93.7 months) led us to retest IDH mutation with a more sensitive technique. Next Generation Sequencing (NGS) was used to retest IDH status in tumor samples, the results of NGS assay were compared with previous finding

Abstract

Background: The 2016 WHO classification of CNS tumors included molecular parameters in addition to histology to redefine many tumor entities. Low-grade glioma (LGG) are divided into isocitrate dehydrogenase (IDH) wild type or mutant. Absence of IDH mutation is a rare event in LGG, and IDH wild type are considered a provisional entity. The technique used to assess IDH mutation is essential to determine the real impact of this tumor type. Methods: The observation of a particularly favorable outcome in a group of 42 patients with a diagnosis of IDH wild type LGG (OS= 93.7 months) led us to retest IDH mutation with a more sensitive technique. Next Generation Sequencing (NGS) was used to retest IDH status in tumor samples, the results of NGS assay were compared with previous finding
