Overview

NCI Definition: A diffusely infiltrating, WHO grade III astrocytoma with focal or dispersed anaplasia, and a marked proliferative potential. It may arise from a low-grade astrocytoma, but it can also be diagnosed at first biopsy, without indication of a less malignant precursor lesion. It has an intrinsic tendency for malignant progression to glioblastoma. (WHO) [1]

Anaplastic astrocytomas most frequently harbor alterations in TP53, IDH1, ATRX, EGFR, and CDKN2A [2].

Most Commonly Altered Genes in Anaplastic Astrocytoma

TP53 Mutation, IDH1 Mutation, IDH1 Codon 132 Missense, TP53 Missense, and TP53 c.217-c.1178 Missense are the most common alterations in anaplastic astrocytoma [2].
