Firstly, they involve the assessment of many individual biomarkers of many types, with both genomic and proteomic markers requiring assessment for complete profiling. Secondly, the interpretation of one biomarker is often critically dependent on the presence or absence of other biomarkers. And finally, this vast array of testing must be delivered often on very small samples.

Many more pathology-oriented AI tools, with a variety of uses across the patient pathway, are on the horizon and include the possibility of multimodal integration. However, for AI in pathology to be used effectively and its benefits realized, there needs to be widespread ‘business as usual’ use of digital laboratory workflows and digital reporting.

In this article, we provide an update on the current progress of AI development in histopathology including the AI tools currently available and potential future applications.
