Data collection arrangements
We plan to continue building a mammographic image research database that is representative of the population. The existing database comprises mammograms from approximately 188,000 women, performed as part of the NHS Breast Screening Programmes at Cambridge and Norwich between 2011 to 2022. Extension of the database will include Cambridge and Norwich, as well as other NHSBSP within the UK, up until 2030. This database will be an essential resource for the testing of algorithms as well as the creation and development of new algorithms.
All data will be collected from pre-existing records at each of the participating sites, and the National Health Service Breast Screening Programme. The database will contain both mammographic images and the clinical data that corresponds to the image (e.g. if a cancer is present, which side is the cancer and what is the type of cancer present).
Identifiable data will be stored separately and will remain at Cambridge University Hospitals NHS Foundation Trust under information governance procedures with the Data Controller, who is also part of the direct care team. Only de-identified data will be used for research and will be stored at the University of Cambridge.Research programme
Advancements in computer algorithms to perform tasks at the same level or better than humans could provide an alternative approach to reading mammograms, assisting readers with the high volume of scans as well as improving cancer detection and predicting a patient’s overall breast cancer risk. The studies conducted using the database will benchmark the performance of computer algorithms for comparison between similar algorithms. Ensure only algorithms that perform highly proceed to further expensive testing. As well as create and develop new algorithms that can help improve cancer detection. The database will be stored, and a Database Access Committee will be formed at the University of Cambridge / Cambridge University Hospitals NHS Foundation Trust. Academic institutions (e.g. Universities) and commercial companies will apply to the Database Access Committee for use of the database. Approved access will allow primarily for algorithms to be tested, developed and created at University of Cambridge / Cambridge University Hospitals NHS Foundation Trust with research staff. In certain strictly controlled circumstances academic institutions and commercial companies might be given access to part of the de-identified database for specific agreed research purposes. Research contracts will be put in place with all external organisations seeking use of the database.
