title: Carboplatin and teniposide concurrent with radiotherapy in patients with glioblastoma multiforme: a phase II study.
abstract: BACKGROUND
  The outcome after treatment for glioblastoma remains poor. Therefore, the authors evaluated the long term efficacy and toxicity of treatment with radiotherapy and concurrent carboplatin plus teniposide followed by three cycles of carmustine in patients who underwent resection for glioblastoma.
  
  
  METHODS
  Fifty-six newly diagnosed patients with glioblastoma underwent radiotherapy (1.8-2 gray [Gy]/day, 5 days a week using limited fields up to 60 Gy), and concurrent chemotherapy with carboplatin (350 mg/m2) on Days 1, 22, and 43, and teniposide (50 mg/m2) on Days 1, 2, 3, 22, 23, 24, 43, 44, and 45. Four weeks after the end of radiotherapy, patients were given carmustine (200 mg/m2) every 8 weeks for 3 cycles. Treatment then was suspended, but if disease progression was found, treatment was resumed using different drugs.
  
  
  RESULTS
  All 56 patients were evaluated for time to progression (TTP) and median survival time (MST). The TTP was 7.5 months and the MST was 12.5 months. Toxicity manifested as thrombocytopenia and in most cases was acceptable. Four patients (7.1%) had radiation necrosis at 2, 2, 7, and 9 months, respectively, from the end of radiotherapy.
  
  
  CONCLUSIONS
  The results obtained in the current study with concurrent radiochemotherapy in patients with glioblastoma are comparable to the best results reported using radiotherapy alone followed by chemotherapy with nitrosoureas.
