This suggests that TCF12 alterations play a role in dictating an aggressive phenotype in AO. Gliomas are tumors that arise from the glial, or supportive cells of the brain. Sci. Although 9p losses can be found in many gliomas, they more commonly occur in higher grade tumors (grades 3 and 4), which make the CDKN2A gene or p16 protein (CDKN2A product) potential players involved in the malignant progression and anaplastic transformation of low-grade gliomas into higher grades (He et al., 1995; Ueki et al., 1996; Watanabe et al., 2001).

Their good prognosis relative to other parenchymal tumors probably stems from inherently less aggressive biological behavior and a favorable response to radiation and chemotherapy. Better prognosis compared to astrocytic tumors. For patients with astrocytic tumors, EORTC26951 and RTOG9402 did not show any benefit of PCV with RT. (1995). In this review article, we describe the clinical management of AO and summarize the different molecular pathways that drive the development, maintenance, and treatment response of these tumors. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press. Nat. The interim report from the RTOG0131 trial suggests that combination therapy with TMZ and XRT is well tolerated in patients with AO being treated with neoadjuvant TMZ for 6 months, followed by TMZ and concurrent XRT (Tork and Atkinson, 2020). This means it begins in the brain or spinal cord. To establish the diagnosis of AO, a pathological sample is crucial.

In a population of patients with oligodendroglial tumors, four cases exhibited absent CIC expression with no detectable mutations, suggesting that alterations affecting CIC could occur through other unidentified mechanisms (Chan et al., 2014). Oligodendrogliomas have a fried egg appearance under the microscope with sheets of round nuclei surrounded by clear cytoplasm. Acta Neuropathol. 2019 Sep 23. This transition to an integrated morphological and molecular diagnosis may result in the disappearance of oligoastrocytoma as an entity, but brings new challenges as well.
