In line with the current literature, patients’ age at diagnosis showed a statistically significant difference (p < .05) with the IDH1 mutant group having a younger mean age than the IDH1 wild one.23 Concerning pathology, the majority of glioblastomas were IDH1 wild type, while the majority of anaplastic astrocytomas were IDH1 mutant, as expected. This evidence concerns the gene IDH1 and anaplastic astrocytoma.
