Neuro-oncology: Implications of the molecular era.

The field of neuro-oncology has recently experienced a renaissance in the understanding of the molecular underpinnings and pathophysiology of glioma. Genetic markers have significant implications regarding treatment responsiveness and prognosis and are now the primary basis for classification. This article gives an updated understanding of the pathogenesis and mechanisms of resistance of glioma via discussion of 4 molecular and genetic markers: MGMT, IDH , 1p/19q, and TERT .
