In a subgroup analysis, oligodendroglioma diagnosis was a favorable prognostic factor resulting in increased overall and progression-free survival; however, oligodendrogliomas were classified histologically in this study, not by 1p/19q status.

Oligodendroglioma: pathology, molecular mechanisms and markers Oligodendrogliomas are primary glial brain tumors that are divided into grade 2 and grade 3 tumors, with grade 3 tumors showing anaplastic features such as microvascular proliferation, necrosis, and increased mitotic rate; distinction between the two grades can be pathologically difficult. doi: 10.3171/JNS/2008/109/11/0835, Sherr, C.

Pathophysiology Cell of origin is unknown, although the commonality of IDH mutation across IDH mutant astrocytoma and oligodendroglioma suggests a common histogenesis in these tumors; similarly, single cell sequencing of IDH mutant gliomas suggests this as well ( Acta Neuropathol 2009;118:469, Science 2017;355:eaai8478 ) Etiology Missing chromosomes (parts of your genes) can cause cells to grow into a tumor. 2015;22:5058.

The European Organization for Research and Treatment of Cancer study 26951 (EORTC26951) and RTOG9402 showed an increase in OS and PFS when PCV is added to radiotherapy (RT) in patients with 1p19q co-deleted oligodendrogliomas (Cairncross et al., 2013; van den Bent et al., 2013a).
