Ministers have cut millions of pounds of funding for potentially life saving AI cancer technology in England, which cancer experts warn will increase waiting times and could cause more patients to die.
Contouring is used in radiotherapy to ensure treatment is as effective and safe as possible. The tumour and normal tissue is “mapped” or contoured on to medical scans, to ensure the radiation targets the cancer while minimising damage to healthy tissues and organs.
Normally, this is a slow, manual process that can take doctors between 20 and 150 minutes to complete. AI auto-contouring takes less than five minutes and costs around £10-£15 per patient.
Research shows that AI contouring can cut waits for radiotherapy by more than five days for breast cancer patients, up to nine days for prostate cancer patients and three days for lung cancer patients.
In May 2024, the Conservative government announced £15.5m over three years to fund AI auto-contouring for all hospitals providing radiotherapy. Work continued on the scheme after the general election, with online webinars and follow-up calls for radiotherapy departments held in September.
The 51 trusts offering radiotherapy continued to work on installing the cloud-based technology, with a number using it early, in the belief the funding was secured.
But in February, in an email seen by the Guardian, Nicola McCulloch, the deputy director of specialised commissioning at NHS England, said the funding had been cancelled “due to a need to further prioritise limited investment”. There would no longer be a centrally funded programme to support implementation of the technology, she said.
The decision means many radiotherapy departments face a return to manual contouring, prompting accusations that the government is ditching digital and going back to analogue cancer care.
Analysis by Radiotherapy UK has calculated that removing funding for AI contouring in England will add up to 500,000 extra days to waiting lists for breast, prostate and lung cancer alone and leave each of the 51 trusts with a £300,000 shortfall.
The chair of Radiotherapy UK, Prof Pat Price, said: “The government cannot laud the advent of AI in one breath, and allow this to happen. Far from moving from an analogue to digital NHS, when it comes to radiotherapy it feels like the opposite is happening. This wrong-footed decision will exacerbate the impact of severe staff shortages.”
The leading oncologist urged ministers to intervene. “Some departments are so short-handed that they’re shutting machines down because no one is there to operate them and nationally, radiotherapy vacancy rates are running at 8%. This investment in AI could have alleviated some of these pressures. Without it, cancer patients will wait longer than necessary for treatment, potentially costing their lives.”
