A Phase II Study of Multiparametric MR-Guided High Dose Adaptive Radiotherapy With Concurrent Temozolomide in Patients With Newly Diagnosed Glioblastoma
This study will investigate whether or not intensified radiation therapy adapted during the radiation treatment course to high-risk, treatment-resistant tumor regions will improve overall survival in patients with newly diagnosed glioblastoma (GBM) compared to conventional chemoradiotherapy.
• Provision of signed and dated informed consent form
• Stated willingness to comply with all study procedures and availability for the duration of the study
• Newly diagnosed, histologically-confirmed supratentorial WHO grade IV gliomas including glioblastoma (all variants) and gliosarcoma. Prior low-grade glioma without prior RT, now with malignant progression are eligible.
• Karnofsky performance status \>=70
• Minimal life expectancy of 12 weeks
• Adequate bone marrow reserve (Hemoglobin ≥ 10 g/dL, absolute neutrophils ≥ 1500/mm3, platelet count ≥ 100,000/mm3), acceptable liver function (total bilirubin ≤ 2 x upper limit of normal (ULN) (unless elevated bilirubin is related to Gilbert syndrome), and ALT/AST ≤ 5 x ULN) and renal function (serum creatinine ≤ 2.0 mg/dL) within 14 day prior to registration. Eligibility level for hemoglobin may be reached by transfusion.
• Maximal contiguous diameter of tumor based on high b-value diffusion MRI and DCE perfusion MRI ≤5 cm
• Patients must be registered within 6 weeks of most recent resection
• Females of child-bearing potential must have a negative pregnancy test within 14 days prior to registration. Patients with reproductive potential must agree to use an effective contraceptive method during treatment and study participation.
