Furthermore, considering all histological subgroups of LGG, higher GPX7 was significantly correlated with poor OS in astrocytomas (HR = 2.6; Logrank p = 0.017) (Fig. 4b), oligoastrocytomas (HR = 5.8; Logrank p = 0.0085) (Fig. 4c) and oligodendrogliomas (HR = 3.1; Logrank p = 0.013) (Fig. 4d) and poor DFS in astrocytomas (HR = 2.2; Logrank p = 0.029) (Fig. 4b). This evidence concerns the gene GPX7 and oligodendroglioma.
