The role of IDH2, on the other hand, is limited to the mitochondria where it catalyzes the same reaction as part of the tricarboxylic acid cycle (TCA). No use, distribution or reproduction is permitted which does not comply with these terms. Lancet 390, 16451653. Oligodendrogliomas are a type of glioma that are believed to originate from the oligodendrocytes of the brain or from a glial precursor cell.

At the molecular level, 9p losses result in the loss of the cyclin-dependent kinase inhibitor CDKN2A gene, which normally inhibits cellular division. Around 60% of people have a seizure before being diagnosed. Neurol Med Chir (Tokyo). Science 324, 261265. PCV chemotherapy for recurrent oligodendrogliomas and oligoastrocytomas. 7, 205207. In the cytosol, the product of the reaction catalyzed by IDH1, alpha-KG, has been reported to be involved in multiple cellular pathways including hypoxia sensing, lipogenesis and epigenetic modification through its action on alpha-KG dependent dioxygenases such as TET and JmjC and other enzymes (Mason et al., 1996; Buckner et al., 2003; Abrey et al., 2006; Taliansky-Aronov et al., 2006). The most common sign of an oligodendroglioma is a seizure. (2016). Oncol.

Their good prognosis relative to other parenchymal tumors probably stems from inherently less aggressive biological behavior and a favorable response to radiation and chemotherapy. First, like most primary brain neoplasms in adults, this neoplasm is usually in the supratentorial brain, most commonly in the frontal lobes. Upon reanalysis of RTOG 9802 after molecular classification, AO patients with IDH-mutated tumors actually showed a survival benefit when treated with PCV chemotherapy (Cairncross et al., 2014).

Although one survey showed that 34% of neuro-oncologists suggested delaying XRT in patients with 1p19 co-deletions (Abrey et al., 2007), clinical trials addressing the efficacy of delayed XRT in this subset of patients are needed.
