PhD student Esme analysing tissue samples
A new partnership involving our clinicians is testing an artificial intelligence-based system to see if it could help to more quickly diagnose one of the most aggressive forms of breast cancer.
The project aims to develop computer 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.
The partnership is between Guy’s and St Thomas’, King’s College London and the software company Owkin. The research will involve historical samples from consenting breast cancer patients at Guy’s and St Thomas’.
Up to a quarter of all breast cancer cases are HER2-positive breast cancer, 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 assessing HER2 levels involves careful analysis by specialised pathologists. At present, pathologists analyse tissue sample slides to detect the presence of HER2 proteins.
The new AI models being built will be ‘trained’ on hundreds of historical tissue samples. It is hoped that this will help the system detect the over-expression of HER2. It is hoped that in the future, these might be tested to see whether they aid in assessing and triaging patients for treatment.
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.”
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.”
