Patients with low-grade gliomas can be conventionally stratified into high risk and low risk categories, with risk referring to risk of tumor progression or recurrence. [QxMD MEDLINE Link]. (2018). Another factor that increases probability of survival in low-grade gliomas is a high performance status. Overexpression of PDGF system components, particularly the subtype receptor (PDGFR), was detected in Southern and Fluorescence in situ hybridization (FISH) analyses 4/41 AO. 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).

Treatments are decided by the patients healthcare team based on the patients age, remaining tumor after surgery, tumor type, and tumor location. (2017). Oligodendroglioma: pathology, molecular mechanisms and markers For nearly a century, the diagnosis and grading of oligodendrogliomas and oligoastrocytomas has been based on histopathology alone. Filipski, K.; Braun, Y.; Zinke, J.; Roller, B.; Baumgarten, P.; Wagner, M.; Senft, C.; Zeiner, PS. [Full Text]. Oligodendrogliomas usually appear as a single tumor with well-defined borders. Treatment is with surgery, when possible. Interestingly, an in vitro treatment of cells with D-2HG also induced a similar methylation pattern (Lu et al., 2012) which further supports the vital role of this metabolite in epigenetic alteration and tumor formation.

Another DNA-binding protein found mutated in AO is FUBP1. Another currently ongoing phase I study (NCT04135807) is assessing the efficacy of an implantable microdevice in the brain before tumor resection is initiated. As for the clinical relevance of these molecular markers, inactivating mutations affecting FUBP1 have correlated with a shorter time to recurrence and CIC mutations have been associated with worse prognosis, especially in those patients with 1p/19q co-deleted oligodendrogliomas (Chan et al., 2014; Michaud et al., 2018). 9, 860864.
