Cannabis effective in treating brain tumors

Scientists have managed to shrink one of the most aggressive brain cancers both in the lab and in mice by combining cannabinoids with radio therapy. Experts have shown that when certain parts of cannabis are used to treat cancer tumours alongside radio therapy treatment the growths can virtually disappear.

A research by specialists at St George’s, University of London, studied the treatment of brain cancer tumours in the laboratory and discovered that the most effective treatment was to combine active chemical components of the cannabis plant which are called cannabinoids. Two of these called tetrahydrocannabinol (THC) and cannabidiol (CBD) were tested as part of the research into brain cancer which is particularly difficult to treat and claims the lives of about 5,200 each year, researchers said.

It also has a particularly poor prognosis as the rate of survival after five years of patients’ diagnosis is around 10 per cent. Cannabinoids are the active chemicals in cannabis and are also known more specifically as phytocannabinoids. There are 85 known cannabinoids in the cannabis plant. The new research is the first to show a drastic effect when combining THC and CBD with irradiation. Tumours growing in the brains of mice were drastically slowed down when THC/CBD was used with irradiation. Also Read – This potential drug combination can treat fatal childhood brain cancer

‘The results are extremely exciting. The tumours were treated in a variety of ways, either with no treatment, the cannabinoids alone, and irradiation alone or with both the cannabinoids and irradiation at the same time,’ Dr Wai Liu, Senior Research Fellow and lead researcher on the project, said. ‘Those treated with both irradiation and the cannabinoids saw the most beneficial results and a drastic reduction in size. In some cases, the tumours effectively disappeared in the animals. This augurs well for further research in humans in the future. At the moment this is a mostly fatal disease,’ said Liu.

‘The benefits of the cannabis plant elements were known before but the drastic reduction of brain cancers if used with irradiation is something new and may well prove promising for patients who are in gravely serious situations with such cancers in the future,’ Liu added. The research team are discussing the possibility of combining cannabinoids with irradiation in a human clinical trial.

The research was published in the Molecular Cancer Therapeutics journal.
