Limited advances in therapy of glioblastoma trigger re-consideration of research policy.

Glioblastoma (GB - WHO grade IV) is the most frequent and lethal primary brain tumour with median overall survival of 7-15 months after diagnosis. As in other cancer research areas, an overwhelming amount of pre-clinical research acquisitions in the GB field have not been translated to patients' benefit, potentially due to inappropriate treatment schedules and/or trial designs in the clinical setting. The recent failure of promising anti-VEGF bevacizumab to improve GB patients' overall survival recapitulates this sense of frustration. The following measures are proposed.
