IDH-wildtype diffuse astrocytomas that contain TERT promoter mutations, chromosome 7 gain/10 loss, and/or EGFR amplification, correspond to a WHO grade IV diagnosis and should be classified as Diffuse astrocytic glioma, IDH-wildtype, with molecular features of glioblastoma, WHO grade IV (DAG-G)...
Most WHO grade 2 astrocytomas harbour IDH mutations. Gemistocytic astrocytoma is a distinct variant of IDH-mutant astrocytoma, WHO grade 2. Maximal surgical resection, if safely feasible, is the best initial therapeutic approach84. Watch-and-wait strategies without the establishment of an integrated...
hyperintense lesion involving the left temporal lobe, left insula, and inferior left frontal lobe. (Bottom) T1WI after contrast administration shows no contrast enhancement of this low-grade astrocytoma.
Results: 63 initial diagnosed IDH-mutant diffuse astrocytomas including 46 patients with grade 2-3 and 17 patients with uncertain grade. While, 5.2% of GBM (9/174) harbored IDH1/2 mutation which should be redefined as diffuse astrocytoma, IDH-mutant, WHO 4 grade. And these patients had a...
They were absent in the 17 grade II and III astrocytomas in children, and the 34 pilocytic astrocytomas. ATRX alterations closely overlapped with mutations in IDH1/2 (p TP53 (p p IDH1/2 and TP53 mutations. Combined alteration of these genes may contribute to drive the neoplastic ...

Grade 2–3 astrocytoma, we also assessed the model’s ability in classifying these two categories (task 3). In these two subgroups, our model achieved high performance with AUCs ranging from 0.935 to 0.984 in all cohorts, as shown in Fig.4i–land Table1. On the other hand, the IDH-...
