Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In newly diagnosed glioblastoma patients aged 70 years or older who are suitable for concurrent temozolomide, the optimal dose of radiation therapy is controversial . The purpose of this study is to compare conventional radiotherapy of 60 Gy (6 weeks) versus hypofractionated radiotherapy of 40 Gy (3 weeks) in terms of overall survival as the primary endpoint along with progression-free survival, toxicity, quality of life, and prognostic biomarkers.
