Purpose
Fotemustine is a nitrosourea compound used for the treatment of malignant gliomas, especially in France. Recently, an EORTC-NCIC study has shown that a concomitant combination of radiotherapy plus temozolomide (an oral cytotoxic drug) improved survival in glioblastoma patients. We set out to test a concurrent combination of radiotherapy and fotemustine for newly malignant gliomas.
Methods
A prospective single-center phase II study opened for accrual in September 2004. Patients over 18 years of age able to give informed consent and with histologically proven, newly diagnosed supratentorial malignant gliomas were eligible. All patients were treated by a standard cranial irradiation (conformal irradiation, tumor bulk plus a margin of 2.5 cm) and concomitant daily administration of 10 mg/m2 of fotemustine (5 days per week, 6 weeks, 1 h 30 min before radiation therapy). Adjuvant chemotherapy, fotemustine, was administered at tumor progression as standard and classic regimen.
Results
Twenty-two patients were enrolled, 16 men and 6 women, median age 56 years (range 32–74), median Karnofsky performance status 70 (range 60–90). Histology included 16 glioblastomas, 3 anaplastic astrocytomas, 2 anaplastic oligodendrogliomas and 1 mixed glioma. Eight patients underwent surgery (three total resections). Fourteen patients had a stereotactic biopsy. The concurrent radiotherapy–fotemustine combination was well tolerated: toxicity was mild and three hematologic toxicities grade 3–4 were observed. Median survival from the initial diagnosis was 9.9 months, two patients are currently alive. Median survival was 11 months for surgery and 9 months for stereotactic biopsy.
Conclusions
Concomitant radiotherapy–fotemustine combination is safe and well tolerated. Overall survival of over 10 months for the whole population compares favorably with other reports.
