With almost 12 years of follow-up, patients harboring tumors with 1p19q co-deletions showed an improved survival when treated with PCV and RT as compared to RT alone (EORTC26951: 157 vs. 50 months; RTOG9402: 14.7 vs. 7.3 years).

Douglas E Ney, MD Associate Professor of Neurology and Neurosurgery, Director of Neurology Residency Program, University of Colorado School of Medicine 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). Recently, immunotherapy has been explored as a potential treatment modality. 56-64. Oligodendroglioma is a molecularly defined diagnosis requiring demonstration of both: Unbalanced translocation between chromosome 1 and 19, resulting in whole arm loss of 1p and 19q chromosomal material (1p / 19q codeletion), Incomplete or partial deletions are not compatible with oligodendroglioma diagnosis, Often absent in teenagers with oligodendroglioma (, Loss of H3K27 trimethylation by immunohistochemistry (. 129, 19. In a recent case report by Yu et al. However, upon multivariate analysis there was no significant difference in overall survival (OS). TERT mutations in glioma are often found within the promoter region. 17, 15161525. Click. 24, 27072714.

The wildtype (WT) TERT group was associated with good prognosis only in IDH1/IDH2 WT (IDH-WT) grade II/III astrocytomas. Procarbazine, CCNU, vincristine (PCV) chemotherapy for benign oligodendroglioma. Lately, IDH 1 and 2, which are known to generate nicotinamide adenine dinucleotide phosphate (NADPH), have been heavily observed. 21(13):2525-8. This tumor, previously diagnosed as GBM-O, WHO grade IV featured mostly cells resembling astrocytoma (, Example where molecular reclassification does not affect tumor grade.
