Using a Pre-Radiation Window to Identify Potentially Active Cytotoxic Agents in Adults with Newly Diagnosed Glioblastoma

Therapies shown to improve outcomes in patients with recurrent cancers are commonly used in the neoadjuvant setting to optimize surgery, reduce radiation fields, and treat micro-metastatic disease. While pre-radiation chemotherapy (PRC) use has flourished in systemic cancers, it has not in glioblastomas. This review documents these trajectories and highlights the potential of PRC to rapidly and safely screen cytotoxic drugs for efficacy in patients with newly diagnosed glioblastoma.
