This has an impact especially in cases of Acute Promyelocytic Leukemia (APL) that require urgent treatment. Integration of automated computational hematopathology into clinical workflows can improve the throughput of these services and reduce cognitive human error. However, a major bottleneck in deploying such systems is a lack of sufficient cell morphological object-labels annotations to train deep learning models. We overcome this by leveraging patient diagnostic labels to train weakly-supervised models that detect different types of acute leukemia. We introduce a deep learning approach, Multiple Instance Learning for Leukocyte Identification (MILLIE), able to perform automated reliable analysis of blood films with minimal supervision. Without being trained to classify individual cells, MILLIE differentiates between acute lymphoblastic and myeloblastic leukemia in blood films. More importantly, MILLIE detects APL in blood films (AUC 0.94 {$\pm$} 0.04) and in bone marrow aspirates (AUC 0.99 {$\pm$} 0.01). MILLIE is a viable solution to augment the throughput of clinical pathways that require assessment of blood film microscopy.}, author = {Manescu, Petru and Narayanan, Priya and Bendkowski, Christopher and Elmi, Muna and Claveau, Remy and Pawar, Vijay and Brown, Biobele J and Shaw, Mike and Rao, Anupama and Fernandez-Reyes, Delmiro}, keywords = {Acute lymphocytic leukaemia, Acute myeloid leukaemia, Computational science, Leukaemia, Pathology} }
