Fig. 2. Clinical applications of basic and advanced deep-learning (DL) image analysis in histopathology.
DL pathology can be applied to tumour detection and identification of subtype (basic applications) or to predict clinical features of interest (advanced application). Published studies (indicated by reference number) are classified according to the level of evidence (monocentric (internally approved), multicentric (externally approved) or FDA approved). a Basic image analysis tasks, including tumour detection, grading and subtyping. b Advanced image analysis tasks, including those that exceed pathologists’ routine capacities, such as prediction of mutation, prognosis and response.
