Guy's and St Thomas' NHS Foundation Trust and King’s College London are working with AI startup Owkin to develop an AI model to speed up the diagnosis of one of the most aggressive forms of breast cancer.
The partnership is developing deep learning models to predict patients whose breast cancer tests positive for a gene called HER2, a signature that plays an important role in the progression of aggressive forms of breast cancer.
Up to a quarter of all breast cancer cases are HER2-positive, affecting up to 14,000 women in Britain every year. This type of cancer is more responsive to certain treatments. It is hoped that using AI will allow quick and accurate assessment of the presence of HER2, ensuring the thousands of women who are diagnosed with HER2-positive breast cancer every year receive targeted treatment as soon as possible.
The use of anti-HER2 therapies has dramatically improved survival rates for breast cancer patients. However, accurately quantifying HER2 levels remains a challenge for doctors. At present, human pathologists analyze tissue sample slides to detect the presence of HER2 proteins. The new AI models being built will use deep learning trained on hundreds of retrospective tissue samples to effectively detect the over-expression of HER2. The trust, which is one of the biggest in the country, plans to use this research to build an AI tool that could accurately pre-screen breast cancer patients for HER2, with the potential for it to be rolled out across the NHS.
Thomas Clozel, Co-Founder and CEO of Owkin and former clinical onco-hematologist, said:
While breast cancer treatment has been transformed in recent decades, the disease still takes three quarter of a million lives every year. By using AI to better spot some of the most aggressive forms of the cancer, it has the potential to radically improve outcomes for patients across the NHS and beyond.
Dr Sheeba Irshad, breast cancer medical oncologist at Guy’s and St Thomas’ said:
Anti-HER2 therapies are a class of medicines used to treat all stages of HER2-positive breast cancer, from early-stage to metastatic. HER2 evaluation is a complex and evolving field. This is an exciting partnership between Owkin, King’s College London and Guy’s and St Thomas’ to help understand if artificial intelligence methods such as deep learning algorithms have the potential to facilitate clinical decision-making in the breast cancer patient pathway.
In November, Owkin became a ‘unicorn’ – a startup valued at more than $1 billion – through a new $180 million investment from French pharmaceutical giant Sanofi. It aims to supercharge cancer research through federated learning, a novel framework for building AI models that allows the masses of data stored in hospitals and pharmaceutical companies to be securely analyzed by AI models without the data leaving the source.
