This multi-center prospective phase 3 clinical trial will enroll 369 patients with newly diagnosed glioblastoma. Patients will be randomly allocated with 1:1:1 to three groups: Control Group, standard-dose photon radiotherapy (60 Gy); Study Group A, standard-dose proton radiotherapy (60 GyE); Study Group B, standard-dose proton radiotherapy (60 GyE) plus induction carbon-ion radiotherapy boost (15GyE/3F). All patients will receive concurrent and adjuvant temozolomide according to the Stupp protocol. The primary endpoint is overall survival (OS). The secondary endpoint is progression-free survival, side effect and quality life.
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).
