Artificial intelligence has shown promise in pathology for years, but evidence from live clinical deployment has been scarce. The Articulate Pro study, led by Oxford's Nuffield Department of Surgical Sciences and published in NPJ Digital Medicine, is among the first evaluations of AI used in real time within NHS histopathology practice, assessing the Paige Prostate suite across Oxford University Hospitals, North Bristol and University Hospitals Coventry and Warwickshire NHS trusts.
More than 1,000 men's prostate biopsies were assessed with the AI working alongside expert histopathologists. The system identified suspected cancerous areas that were difficult to spot and in some cases prompted an amended grade of tumour aggressiveness; in a small number of cases this changed the clinical management options offered to patients. Some centres saw faster reporting turnaround, meaning results could reach patients a day sooner, alongside a measurable reduction in requests for immunohistochemistry staining.
Fewer staining requests matter for overstretched NHS laboratories, promising workflow relief and cost savings. The study was funded by the Department of Health and Social Care with the National Institute for Health and Care Research and the Accelerated Access Collaborative through the AI in Health and Care Awards, and involved people with lived experience of prostate cancer at every stage. Its authors argue the findings pave the way for large-scale adoption of AI-assisted diagnosis across the health service.
