Significance of radiation therapy in frontal glioblastoma patients and exploration of optimal treatment modality: a real-world multiple-center study based on propensity score matching

Glioblastoma (GBM) exhibits diffuse and invasive growth patterns, with a 5-year overall survival (OS) rate of 5-10%. In addition, approximately 40 percent of GBMs are localized in the frontal lobe, a region closely linked to essential life functions including cognition, so that it cannot be completely eradicated through surgical intervention, leading to very poor prognosis. Postoperative therapy is an essential treatment modality. The aim of this study is to explain the possible role of radiation therapy (RT) in the treatment of frontal GBM, providing more evidence for clinical application.
