Oligodendroglioma is genetically defined as a tumor confirmed to harbor either an IDH1 or IDH2 mutation along with co-deletion of chromosome arms 1p and 19q. A randomized clinical trial is currently in progress to compare the efficacy of PCV or TMZ when combined with RT in 1p19q co-deleted tumors (CODEL: NCT00887146). IDH1 Arg-132 mutant promotes tumor formation through down-regulating p53. Bello MJ, Vaquero J, de Campos JM, et al. (2011). Oligodendrogliomas account for approx 5% of all gliomas.

All of the cases have completed central pathological review and met the PLNTY criteria of the following: 1) infiltrative and nodular growth pattern; 2) invariable presence of oligodendroglioma-like cellular component with more or less polymorphic cellular elements including pleomorphic and spindle cells; 3) intense immunolabeling for cluster of (2013). It has therefore been suggested that complete 1p/19q codeletion be required for the diagnosis of 'canonical oligodendroglioma'. Sci.

It is believed that anaplastic oligodendroglioma (AO) can progress from a lower grade oligodendroglioma after the acquisition of specific genetic alterations (Youssef and Miller, 2020). (Jan 2013).

For instance it needs to be sorted out how (histopathological) criteria for grading of 'canonical oligodendrogliomas' should be adapted, how pediatric oligodendrogliomas (known to lack codeletions) should be defined, which platforms and cut-off levels should ideally be used for demonstration of particular molecular aberrations, and how the diagnosis of oligodendroglioma should be made in centers/countries where molecular diagnostics is not available.
