Bubbly drink trial 'to boost cancer therapy' - BBC News

Bubbly drink trial 'to boost cancer therapy' - BBC News



Citando:

"One reason thought to behind this is that cancers grow rapidly and their blood supply fails to keep up - leaving tumours with torturous, poorly-formed blood vessels that don't deliver oxygen-rich blood as well.

Prof Eleanor Stride, from Oxford University, says the lack of oxygen makes cancer cells "go into survival mode" making them more hardy and therefore less responsive to radiotherapy and drugs.

This is a particular problem for hard-to-treat cancers such as tumours of the pancreas, she says.

The team has already found that injecting oxygen in mice with cancer and then giving them chemotherapy leads to more successful treatments.

They recently carried out a small-scale trial of an oxygen-rich drink in mice.

The next stage is to repeat the mice experiments in much larger numbers, before human trials are considered.

But Prof Stride says: "I wouldn't suggest people rush out to buy any drinks claiming to be rich in oxygen."
