Abstract

Aim: This multicenter, retrospective study evaluates the clinical benefit (CB) of bevacizumab, alone or in combination, in recurrent gliomas (RG). Patients & methods: The CB was measured as a reduction of corticosteroid dosage and an improvement ≥20 points in the Karnofsky Performance Status lasting ≥3 months. Results: We collected data of 197 RG patients. A CB was observed in 120, patients without significant differences between patients treated with bevacizumab alone or in combination. The rate of patients who achieved a CB and free from progression at 1 year was 21.5 versus 1.4% in patients who did not report CB. Conclusion: The majority of RG patients treated with bevacizumab reported CB. Moreover, patients with CB showed improved survival.
