LTHT Case Study: Can AI help diagnose cancer better?
NPIC is a digital pathology program. We’re using new scanners that allow us to digitize patients biopsies in order to diagnose cancer digitally. A piece of tissue that might be one or two centimetres in size can generate an absolutely enormous digital image. If you print them, they can be the size of a tennis court or a squash court. We can share those images more quickly for second opinions around our own hospital or around the country, and we can also use those images to develop artificial intelligence algorithms that can help us diagnose cancer better.
We’re doing this project at a time when artificial intelligence is becoming very powerful, so when we work with artificial intelligence companies, we can create artificial intelligence that works for every patient across every scanner across the NHS. The best example of that is in childhood tumours. There are only 50 pathologists in the UK that are able to diagnose cancer in children, and they’re in short supply, so our network will allow those pathologists to get second opinions from the experts around the country more rapidly, and that means that people waiting for a diagnosis will get it faster, and they’ll also get a more specialized diagnosis quicker in the course of their treatment.
Part of the work we do is understanding the technology and helping other hospitals to use it. It’s quite a big undertaking to put scanners into a laboratory and start diagnosing cancer digitally, so we have a training centre here at the NPIC centre to ensure that we don’t just deploy the technology across lots of hospitals; we actually help people to use it successfully and safely. One of the research products that we’re undertaking with the infrastructure we built is scanning all the patients who are part of the hundred thousand genomes product organized by genomics England.
18 000 of them have had cancer, and we’re taking all their slides from 80 hospitals across the country, bringing them into the NPIC centre, and scanning them to create an enormous resource of pathology images to allow cancer research and to improve the foreign national program with their substantial amount of scanners being deployed in the north of England, but also two national networks to support children’s Cancer and soft tissue and bone cancers across the country. I started training as a pathologist in 1997.
The idea that you would be able to train an artificial intelligence algorithm to diagnose cancer would have been unthinkable, and the idea that now just over 20 years later we are actually seriously talking about digitizing the entire NHS pathology service with many petabytes of finished data being created per year is unbelievable but also very exciting, so it really is a revolution in how we diagnose cancer in labs.
Can AI help diagnose cancer better?
Artificial Intelligence (AI) has been predicted to help treatment responses. Through Image analysis and other data, AI algorithms can help identify cancer at an early stage. The NPIC digital pathology programme is using new technology to diagnose cancer digitally.
Through Collaboration and partnership
Working with various Artificial Intelligence companies, it is possible to create AI that works for all patients and scanners across hospitals and the NHS. These partnerships will help create specialised diagnosis in a faster and efficient manner.
The Impact of Technology
With the continuous improvement in AI, the impact of this technology has the potential to boost productivity, information and knowledge sharing and revolutionise the way healthcare professionals diagnose, care, treat and manage cancer in a cost-effective manner.
Improving cancer research
While AI has shown the potential to improve cancer detection, NPIC research has built a digital scanner that can identify and predict the risk of cancer development in children, bone, and soft tissues.
Are the AI tools used by NPIC ready for the real world?
One of NPIC’s key roles is understanding the technology and being able to transfer the knowledge to other healthcare professionals. While scanners are being set up in laboratories and hospitals, NPIC has created a training centre.
