Brief summary

This is a study to determine the safety and effectiveness of high-dose radiation therapy (RT) with concurrent temozolomide in patients with newly diagnosed glioblastoma.

Detailed description

After analysis demonstrated the improved prognostic value of identifying both hypercellular tumor (TVHCV) based on high b-value diffusion-weighted magnetic resonance imaging (DW-MRI) and hyperperfused tumor (TVCBV) based on dynamic contrast-enhanced MRI (DCE-MRI), the study was amended and later-enrolled patients boosted to both TVHCV and TVCBV.

Interventions

Radiation will be delivered once daily for a total of 30 fractions, five days per week.

DRUGTemozolomide

Patients will receive concurrent temozolomide (75 mg/m\^2 daily for 6 weeks). Adjuvant temozolomide will be given at 150-200 mg/m\^2, D1-5 every 28 days for a minimum of six cycles and will be started approximately four weeks following completion of radiotherapy.

Inclusion criteria

Median Progression-free SurvivalMedian follow-up time was 26 monthsFrom start of RT until disease progression or death, or until date of last imaging follow-up, estimated using Kaplan-Meier. Progression is defined by any of the following: \>= 25% increase in sum of the products of perpendicular diameters of enhancing lesions (compared with baseline if no decrease) on stable or increasing doses of corticosteroids; a significant increase in T2/FLAIR non-enhancing lesions on stable or increasing doses of corticosteroids compared with baseline scan or best response after initiation of therapy, not due to comorbid events; appearance of any new lesions; clear progression of non-measurable lesions; or definite clinical deterioration not attributable to causes other than tumor, or to decrease in corticosteroid dose. When pathologic confirmation was unavailable, progression was defined as worsening enhancement based on imaging with or without adjunctive advanced imaging including perfusion MRI or magnetic resonance spectroscopy, when clinically indicated.

EORTC QLQ-C30 is a 30-item questionnaire to assess the overall quality of life in cancer patients. EORTC QLQ-C30 includes functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting), and other (dyspnea, appetite loss, insomnia, constipation/diarrhea, and financial difficulties). Most questions used 4-point scale (1 'Not at All' to 4 'Very Much'); 2 questions used 7-point scale (1 'Very Poor' to 7 'Excellent'). Scores are averaged, and transformed to 0-100 scale; higher score=better level of physical functioning.

High Dose Chemoradiation
Patients will receive high dose radiation based in part on advanced imaging, and concurrent temozolomide. Four weeks after the completion of chemoradiation, patients will receive adjuvant temozolomide. High Dose Radiation: Radiation will be delivered once daily for a total of 30 fractions, five days per week. Temozolomide: Patients will receive concurrent temozolomide (75 mg/m\^2 daily for 6 weeks). Adjuvant temozolomide will be given at 150-200 mg/m\^2, D1-5 every 28 days for a minimum of six cycles and will be started approximately four weeks following completion of radiotherapy.
