Abstract
Purpose of review: A number of molecular characteristics are essential for accurate diagnosis and prognostication in glioma.
Recent findings: The 2021 WHO classification of brain tumors and recent Food and Drug Administration (FDA) pathology agnostic drug approvals highlight the importance of molecular testing in the management of glioma. For diffuse gliomas, it is important to identify IDH mutations, given the favorable clinical behavior and potential for using FDA approved IDH inhibitors in the near future. MGMT promoter methylation testing is the most established molecular marker for response to temozolomide in IDH wild-type glioblastoma and in turn impacts overall survival. Moreover, identification of certain mutations and molecular markers, such as BRAF V600E, hypermutation or elevated tumor-mutational burden and NTRK fusions allow for the use of FDA approved agents that are tumor-agnostic. Finally, molecular testing opens options for clinical trials that are essential for diseases with limited treatment options like gliomas.
期刊介绍：
This journal aims to review the most important, recently published clinical findings in the field of oncology. By providing clear, insightful, balanced contributions by international experts, the journal intends to serve all those involved in the care of those affected by cancer.
We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas, such as cancer prevention, leukemia, melanoma, neuro-oncology, and palliative medicine. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An international Editorial Board reviews the annual table of contents, suggests articles of special interest to their country/region, and ensures that topics are current and include emerging research. Commentaries from well-known figures in the field are also provided.
