Characterization of molecular pathways for targeting therapy in glioblastoma.
Chin Clin Oncol
Glioblastoma remains the most common malignant brain neoplasm in adults. The available therapies for treatment have only modestly extended survival. Traditional chemotherapy agents have shown only slight effectiveness in controlling this disease. The use of molecular profiling has allowed personalized medicine options to be explored for the care of these individuals. Targeted therapies have shown significant benefit in numerous other cancer types with survival being extended significantly. In glioblastoma, several promising markers have been identified including vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), and programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1). These targets have been shown to play a critical role in glioblastoma formation and proliferation. The pathways of these receptors have been elucidated in detail. This level of understanding has led to the a more robust understanding of possible mechanism of pathway modification. The targeting of these specific markers has led to the development of several selective therapies with additional therapies being evaluated. The clinical trials validating these markers have been promising but have yet to show a clear benefit in brain tumors. This identification of alternative methods to address these markers or identify additional targets may be the key to the fight against this disease. The molecular targeting of glioblastoma pathways may have significant impact on disease control and patient survival.
