Research Collaboration Aims To Improve Breast Cancer Diagnosis Using Ai

Mammogram

A new project to explore how artificial intelligence (AI) could improve breast screening could potentially lead to more accurate detection of cancers.

The project will see a consortium of leading breast cancer experts, clinicians and academics partner with leaders in artificial intelligence (AI) research to explore whether AI could help detect and diagnose breast cancers more effectively.

Led by Imperial College London, the consortium will be based at the Cancer Research UK Imperial Centre.

Clinicians and radiologists from the Centre will work on the research with technical partners at DeepMind Health and the AI health research team at Google, alongside the Cancer-Research UK funded OPTIMAMmammography database at the Royal Surrey County Hospital NHS Foundation Trust.

Breast cancer is the most common cancer in women worldwide, with 1.6 million women around the world diagnosed every year.

In the UK alone, over 150 patients are diagnosed with breast cancer every day, and despite medical advances, it still kills around 11,000 women in this country each year, and 500,000 people globally.

If these initial trials prove successful, AI could make screening services for cancer far more efficient and improve outcomes

– Professor Ara Darzi

Director of the Cancer Research UK Imperial Centre

While early detection and treatment is shown to lead to better outcomes for women with cancer, accurately detecting and diagnosing breast cancer remains highly challenging. Mammograms (an X-ray of the breasts) are used by clinicians to identify cancers early, but breast screening is not perfect.

Thousands of cases are not picked up by mammograms each year, including 30% of cancers that develop between screenings, while false alarms and cases of overdiagnosis are also common.

The new collaboration aims to understand if machine learning tools can help doctors to address these challenges. Machine learning is a form of artificial intelligence in which computer algorithms can learn and improve without being explicitly told how.

Towards increased accuracy

The team believes it has the potential to increase the accuracy of breast screening interpretation, improving the ability to detect breast cancers on mammograms.

The project may also provide women with a better estimate of their risk of breast cancer, which could help guide them in taking actions to prevent it.

As part of this project, machine learning technology from DeepMind Health and the AI health research team at Google will be applied to historic ‘de-identified’ mammograms from around 7,500 women provided by the Cancer Research UK-funded OPTIMAM database at the Royal Surrey County Hospital NHS Foundation Trust.

Harnessing the power of artificial intelligence could enable us to address some of the biggest challenges in breast cancer research

Cancer Research UK’s Executive Director of Research and Innovation

These digital images have been stripped of any information which could be used to identify patients and have been available to research groups around the world for a number of years.

Through this research, the team hope to explore whether it is possible to train computer algorithms to analyse these images, to spot signs of cancerous tissue and alert radiologists more accurately than current techniques allow.

It is hoped that further international research partners will join the project over the next 12-months so that this research, if successful, could eventually lead to technology that will help clinicians around the world to make more accurate diagnoses, leading to earlier detection and intervention for patients.

Professor Ara Darzi, Director of the Cancer Research UK Imperial Centre, said: “This partnership marks an exciting exploration of the potential for artificial intelligence in healthcare.”

He added: “Ultimately, we want this kind of technology to benefit patients and it may be a number of years until this kind of approach is used, but if these initial trials prove successful, AI could make screening services for cancer far more efficient and improve outcomes.”

Dr Iain Foulkes, Cancer Research UK’s Executive Director of Research and Innovation, said: “Harnessing the power of artificial intelligence could enable us to address some of the biggest challenges in breast cancer research, including improving the accuracy of detection.

“Too many cancers are detected at a late stage when they are more difficult to treat. This is why Cancer Research UK is building capacity, forging new partnerships, and supporting a community for early detection research so that more people might survive their disease.”

Dominic King, Clinical Lead, DeepMind Health, said: “We set up DeepMind because we wanted to use artificial intelligence to help solve some of society’s biggest challenges – challenges exactly like breast cancer. For that reason, we’re incredibly excited to be part of this collaboration, working alongside leading researchers to try and tackle this problem, and bring real benefits for cancer patients across the world, and the clinicians who treat them.”

Professor Anne Mackie, Director of Programmes for the UK National Screening Committee at Public Health England, commented: “Mammography is a key service for the NHS in the early detection of breast cancer. Exploring innovative new technologies such as machine learning has the potential to increase the efficiency of these services and make better use of the resources available to NHS screening programmes.”

Dr Nicola Strickland, President of the Royal College of Radiologists and Consultant Radiologist at ICHNT, said: “Image-based population screening to pick up cancer early, when it is still curable, is becoming more and more important. The use of machine learning in medical imaging is still in its infancy, but this exciting research approach could help boost our diagnostic capacity and potentially increase our diagnostic accuracy, as well as speed up the detection of early cancers, which would be of immense benefit to patients.”

Frequently Asked Questions

WHY IS THE RESEARCH BEING CARRIED OUT?The purpose of this research is to explore whether cutting-edge machine learning (a form of artificial intelligence) could help clinicians detect and diagnose breast cancers more effectively than current techniques allow.

Breast cancer is the most common cancer in women worldwide. In the UK alone it is estimated that more than 150 patients are diagnosed with breast cancer every day. Despite advances in treatment, it still kills around 11,000 women in the UK each year, and 500,000 people globally.

Doctors use X-rays of the breast, called mammograms, to spot cancers in breast tissue, but the screening is not perfect. Thousands of cases are not picked up by mammograms each year, including 30% of cancers that develop between screenings, while false alarms and cases of overdiagnosis are also common.

WHAT DATA IS BEING SHARED FOR THIS RESEARCH?The researchers will use X-ray images of the breast (mammograms) from the Cancer Research UK-funded OPTIMAM database, based at the Royal Surrey County Hospital NHS Foundation Trust. DeepMind Health will be provided with secure access to historic, HRA-approved, de-identified mammograms from around 7,500 women. All of these digital images have been stripped of any personal information which could be used to identify a patient.

DID THE PATIENTS HAVE TO GIVE THEIR CONSENT FOR THEIR DATA TO BE USED?The Health Research Authority (HRA), which governs research practices involving NHS data, has approved the project. The HRA approval and DeepMind’s agreement for access to the OPTIMAM database make it clear that data used in this research is not personally identifiable.

When research involves working with this type of data, which is de-identified and with no way for researchers to identify individual patients, explicit consent from patients for their data to be used in this way is not required.

More information about this can be found on the Information Commissioners Office’s website.

HOW LONG IS THE PROJECTED EXPECTED TO LAST?DeepMind’s agreement with Cancer Research Technology Limited, Cancer Research UK’s commercial arm, and the Royal Surrey County Hospital NHS Foundation Trust lasts for twelve months initially, but the parties can agree to extend it.

WHAT WILL HAPPEN WITH THE RESULTS?As with all academic studies, the researchers aim to publish their results following the peer-review process.

WHY ARE GOOGLE AND DEEPMIND BOTH INVOLVED IN THIS PROJECT?Imperial is partnering with Google and DeepMind to ensure the project will benefit from their combined world-leading expertise and Google’s super computing infrastructure, regarded as one of the best in the world.

It is hoped that by bringing together some of the best minds in applied AI from across these two organisations, and partnering them with leading academics and breast cancer clinicians from across the NHS, we might achieve more impactful results on patient care.
