Actionable molecular biomarkers in primary brain tumors.


ABSTRACT: Recent genome-wide studies of malignancies of the central nervous system (CNS) have revolutionized our understanding of the biology of these tumors. This newly gained knowledge provides a wealth of opportunity for biomarker driven clinical research. To date, however, only few of the available molecular markers truly influence clinical decision-making and treatment. The most widely validated markers in neuro-oncology presently are: 1) MGMT promoter methylation as a prognostic and predictive marker in glioblastoma, 2) co-deletion of 1p and 19q differentiating oligodendrogliomas from astrocytomas, 3) IDH1/2 mutations, and 4) select pathway-associated mutations. This article focuses on currently impactful biomarkers in adult and pediatric brain cancers and it provides a perspective on the direction of research in this field.
