The Cancer Drugs Fund in England was a "huge waste of money" and may have caused patients to suffer unnecessarily from the side effects of the drugs, according to UK researchers.
The fund ran from 2010 to 2016, costing £1.27bn, following an election promise made by the Conservatives to pay for cancer drugs the NHS was not funding.
The researchers found only one in five of the treatments was of benefit.
Of the drugs where there was some evidence of benefit, the average was an extra 3.2 months of survival
