  • European Organisation for Research and Treatment of Cancer 22845 randomised trial.

A European study of 314 patients with low grade gliomas randomised to receive either early radiotherapy after surgery or deferred radiotherapy until the time of progression. The main findings were that early radiotherapy did not increase the overall survival but did improve the seizure control. Lancet 2005; 366: 985-90

  • NCOG 6G61 randomised phase III trial.

A North American trial of post-radiation chemotherapy in 148 patients with high grade gliomas with either carmustine alone or combination therapy with PCV. The latter was found to be associated with significantly longer survivals. Int J Radiat Oncol Biol Phys 1990; 18(2): 321-4 and J Neurosurg 1985; 63(2): 2: 18-23

The RCGP covers this topic in statement 12 of the RCGP curriculum, Care of People with Cancer and Palliative Care.

  • Macmillan Cancer Support Clear information on gliomas, their treatment and how to get help, especially useful for patients.
