Significant correlations were observed between SUMF1 overexpression and various factors including IDH status (wild-type or mutant), 1p/19q codeletion, age (≤60 or >60), histological type (astrocytoma, oligoastrocytoma, oligodendroglioma, or glioblastoma), OS event (alive or deceased), DSS event (alive or deceased), and PFI event (alive or deceased). Here, SUMF1 is linked to oligoastrocytoma.
