Bevacizumab alone at 5 mg/kg in an every-3-week schedule for patients with recurrent glioblastomas: a single center experience.

The use of bevacizumab is increasingly reported in neuro-oncology. The most common schedule is 10 mg/kg every 2 weeks. We retrospectively investigated the efficacy of a 3-week schedule of 5 mg/kg bevacizumab in patients with recurrent glioblastomas. Fourteen patients (median age, 46 years) were included in the study. The median number of bevacizumab cycles was 4 (range, 2-8). Five patients (36%) had a partial response, 7 (50%) had stable disease, and 2 (14%) had progressive disease. No grade III-IV toxicities were observed. The median progression-free and overall survival were 3.6 months and 6.4 months, respectively. Every-3-week low-dose single-agent bevacizumab showed substantial activity and a safe profile in patients with recurrent glioblastoma.
