Scientists have developed a drug that destroys brain tumours. Cancerous cells are wiped out as the drug passes through the blood-brain barrier that protects neurons from foreign invaders.
Experiments found the small molecule killed them all, while leaving healthy tissue alone. Results were described as "very promising". The mice were cured - with no relapse after more than six months.
It works in combination with chemotherapy. Tumours quickly returned in peers given only the latter - and spread rapidly. Improved therapies are urgently needed for glioblastomas - which are often incurable.
