Current first-line therapy for
anaplastic astrocytoma is surgery followed by treatment with temozolomide.

Expression level of miR-124a was significantly decreased in
anaplastic astrocytoma and GBMs, when compared to normal brain tissue [77], and also in oligodendroglioma [78].
(1, 5) When increased cellularity, mitosis, and nuclear atypia are present, it is classified as
anaplastic astrocytoma (WHO grade III).
Further, for the treatment of adult patients with newly diagnosed glioblastoma multiforme concomitantly, Temozolomide Capsules are noted along the radiotherapy and also as maintenance treatment and for adult patients with refractory
anaplastic astrocytoma who have intimate disease progression on a drug regimen containing nitrosourea and precarbazine.
Jake's mom, 38-year-old Malini Mayerhauser, has a form of brain cancer called
anaplastic astrocytoma Grade 3.
Transformation of intracranial
anaplastic astrocytoma associated with neurofibromatosis type I into gliosarcoma: case report.
[36], who reported significant increase of IL-10 serum levels in patients with
anaplastic astrocytoma and glioblastoma.
The most widely used system is the World Health Organization (WHO) classification (1979, 1993, 2000, and 2007) that grades astrocytomas (I-IV) based on cytological atypia, mitotic activity, vascular proliferation, and necrosis: pilocytic astrocytoma (grade I), diffuse astrocytoma (grade II),
anaplastic astrocytoma (grade III), and glioblastoma (grade IV).
Malignant gliomas include WHO grade III:
anaplastic astrocytoma, anaplastic oligodendroglioma and anaplastic oligoastrocytoma, and WHO grade IV: glioblastoma and gliosarcoma.
