Proton and Heavy Ion Beam Radiation vs. Photon Beam Radiation for Newly Diagnosed Glioblastoma.

This is a multi-center prospective phase 3 clinical trial to explore the efficacy and side effects of standard-dose photon radiation versus standard-dose proton radiation versus carbon ion boost plus standard proton radiation for newly diagnosed glioblastoma. The patients enrolled will be randomly allocated with 1:1:1 to three group: Control Group, standard-dose photon radiotherapy; Study Group A, standard-dose proton radiotherapy; Study Group B, standard-dose proton radiotherapy plus induction carbon-ion radiotherapy boost. The primary endpoint is overall survival (OS).
