There's only one, very expensive drug available that can penetrate into the brain and attack the most aggressive tumours there, and nothing new on the horizon.
For these patients, the outlook is as bleak as it can get.
But ten years ago, researchers discovered that the out-of-fashion antidepressant drug clomipramine has apparently remarkable anti-tumour properties.
What's more the treatment costs pennies, not hundreds or thousands of pounds.
Yet these scientists have struggled to find anyone to back their research.
And many patients are being given the drug without the scientific proof it is really helping them.
Why is such a promising treatment going to waste? Gerry Northam investigates.
An old antidepressant has unexpected anticancer properties, but no-one is developing it.
