Ki-67 index and FOXM1 protein expression in WHO grade I meningioma with GTR. Comparison of Ki-67 index based on each variable (A: driver gene mutation, B: tumour location, C: subgroups). Comparison of FOXM1 protein expression based on each variable (D: driver gene mutation, E: tumour location, F: subgroups). G: hematoxylin eosin (WHO grade I meningioma in supratentorial lesion with NF2 mutation, scale bar: 50 µm). H: Ki-67 index (WHO grade I meningioma in supratentorial lesion with NF2 mutation, scale bar: 50 µm). I: FOXM1 protein expression (WHO grade I meningioma in supratentorial lesion with NF2 mutation, scale bar: 50 µm). J: FOXM1 protein expression (WHO grade III anaplastic meningioma, scale bar: 100 µm). K: FOXM1 protein expression (brain metastasis from lung cancer, scale bar: 50 µm). FOXM1: forkhead box protein M1; WHO: World Health Organization. GTR: gross total resection; PFS: progression-free survival
