A therapy that would once have been considered a feat of science fiction has reversed aggressive and incurable blood cancers in some patients, doctors report.

The treatment involves precisely editing the DNA in white blood cells to transform them into a cancer-fighting "living drug".

The first girl to be treated, whose story we reported in 2022, is still free of the disease and now plans to become a cancer scientist.

Now eight more children and two adults with T-cell acute lymphoblastic leukaemia have been treated, with almost two thirds (64%) of patients in remission.

For those on the trial, chemotherapy and bone marrow transplants had failed. Apart from the experimental medicine, the only option left was to make their death more comfortable.

And costs go down when you treat more people. There is considerable risk so it makes sense to only use it on patients when it's a choice of a more comfortable death or cure.
