Perspectives of Personalized Chemotherapy of Gliomas Based on Molecular Tumor Profiling.

Perspectives of Personalized Chemotherapy of Gliomas Based on Molecular Tumor Profiling. Prog Neurol Surg. 2018;31:168-179 Authors: Soffietti R, Franchino F, Magistrello M, Pellerino A, Rudà R Abstract Histopathological typing and grading are the cornerstones of the World Health Organization classification of the central nervous system tumors. It provides clinicians with information on the natural course of the disease and thus guides therapeutic choices. Nonetheless, patients with histologically identical tumors may have different outcomes and response to therapy. In recent years, extensive research has been done on three molecular markers in adult gliomas, namely MGMT promoter methylation, 1p/19q co-deletion, and IDH1/IDH2 mutations. These markers may have either a prognostic or a predictive value, differentiation of which is often difficult as both can coexist. At present, MGMT promoter methylation is considered as a predictive marker for response of glioblastoma to chemotherapy with temozolomide, particularly in elderly patients, 1p/19q co-deletion is a molecular signature of oligodendroglial tumors and predictive marker for response of anaplastic gliomas to PCV chemotherapy, and IDH1/IDH2 mutations have a strong favorable prognostic value across all glioma histopathological grades.
