The most common diagnosis was glioblastoma IDH wild type with 596 cases (49.2%), followed by oligodendroglioma grade 2 (n = 109; 9.2%), astrocytoma grade 3 (n = 108; 8.9%), oligodendroglioma grade 3 (n = 76; 6.4%), astrocytoma grade 2 (n = 66; 5.4%), IDH 1/2 mutated astrocytoma WHO grade 4 (n = 45; 3.7%), and diffuse midline glioma, H3K27M- or FGFR1-mutated (n = 15+1; 1.3%) (Table 2). This evidence concerns the gene FGFR1 and astrocytoma (excluding glioblastoma).
