High-grade glial tumors remain among the most aggressive and refractory malignancies, traditionally having a poor prognosis, few treatment options, and few ways to predict which ones might respond to treatment. ... Additionally, recent work has suggested that 1p/19q loss in lower grade oligodendrogliomas and mixed gliomas predicts better ...

Low-grade mixed gliomas have been historically treated with surgery, radiotherapy, or observation. A recent retrospective report of 106 patients with low-grade oligodendrogliomas (77 patients) and oligoastrocytomas (29 patients) concluded that there were no apparent survival differences between immediate and deferred treatment or among choices ...
