A recent study using the Cox model reported that CTSZ, EFEMP2, ITGA5, KDELR2, MDK, MICALL2, MAP2K3, PLAUR, SERPINE1, and SOCS3 were related to the prognosis of glioblastoma multiforme and LGG, while the same dataset (TCGA) was used in this study [58]. This evidence concerns the gene KDELR2 and glioblastoma.
