Artificial intelligence (AI), particularly machine learning (ML), is set to revolutionize cancer research and clinical care by speeding up research, improving diagnostics, and enabling personalized treatment plans. This is especially promising for colorectal (CRC) adenocarcinoma, where specific algorithms have been developed. Digitizing pathology processes within the NHS enhances benefits for CRC patients, allowing pathologists to work remotely and collaboratively. The main benefits include improved workflow and the creation of teaching datasets for ML technology, leading to more reproducible and objective analyses with faster turnaround times. ML can alleviate the workload crisis in clinical pathology by flagging cases for further investigation and providing detailed analysis. Digital pathology represents the future, integrating ML into current care pathways to improve diagnostics and prognostics. This study aims to demonstrate that ML algorithms can run alongside routine pathology, providing timely diagnostic and prognostic information without delaying treatment decisions. It also seeks to evaluate the impact of these algorithms on clinical decision-making. Oxford-based research groups have developed ML algorithms to enhance treatment pathways for CRC patients, leveraging the digitization of clinical pathology to improve diagnostics and prognostication. The PACES study will explore how these algorithms can support or change clinical treatment decisions. As AI in the form of ML is a new and untested healthcare technology, this study aims to determine its use by clinicians and integration into existing care pathways with accredited algorithms. PACES is a clinical utility study focused on care pathways and the potential impact on treatment decisions. To avoid bias, clinicians will receive algorithm results only after making treatment decisions.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

01 Oct 2024 01 Oct 2026

Pseudonymous digital images of histological slides generated as part of routine NHS care will be obtained with participant consent. Images will then be run through three different machine learning algorithms; different algorithm outputs relate to different recommendations in colorectal cancer diagnosis and/or treatment. After a decision on real-life diagnosis/treatment has been made by the participant's medical team, algorithm outputs will be sent to clinicians who will be asked if their recommendation of diagnosis/treatment would have changed if they had received algorithm outputs earlier (e.g., during MDT meetings).


NHS patients aged 18 years old and over with clinical suspicion or confirmed diagnosis of colorectal adenocarcinoma of any stage scheduled for anti-cancer treatment

You can take part if:



You may not be able to take part if:


1. Any other significant disease or disorder which, in the opinion of the investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant’s ability to participate in the trial. 2. Treatment with chemoradiotherapy prior to diagnostic biopsy related to the cancer under study in the past 12 months.


Below are the locations for where you can take part in the trial. Please note that not all sites may be open.

  • Oxford University Hospitals NHS Foundation Trust
    John Radcliffe Hospital Headley Way Headington
    Oxford
    OX3 9DU

Participants will not directly benefit from taking part, however, information gathered from participants in this study may help others with similar conditions in the future. Additionally, data from this study will help us learn how new technologies could be used in real-world clinical settings to help doctors and their patients make better, personalised decisions on cancer treatment in the future. Overall, participation in this study is considered very low risk, as all procedures follow well-established standard NHS processes.
