Abstract: AI for medical imaging: what is missing to make it work?
AI is a promising field in medical imaging and has led to high expectations. However, some pitfalls and challenges have slowed down the development and implementation of these solutions, leading at worse to disappointment or distrust. We will go over the reasons for the difficulties in the practical implementation of AI solutions. At the training level, quality and quantity of data is the main challenge, including the relevance of the available data. At the validation level, there remain many questions on how these solutions should be validated to allow using them reliably and confidently. Finally, the implementation in the clinical workflow is a challenge in itself, both in technical and in clinical terms.

Abstract: AI, Radiomics and Pathomics for Precision Oncology
Traditional biology generally looks at only a few aspects of an organism at a time and attempts to molecularly dissect diseases and study them part by part with the hope that the sum of knowledge of parts would help explain the operation of the whole. Rarely has this been a successful strategy to understand the causes and cures for complex diseases. The motivation for a systems based approach to disease understanding aims to understand how large numbers of interrelated health variables, gene expression profiling, its cellular architecture and microenvironment, as seen in its histological image features, its 3 dimensional tissue architecture and vascularization, as seen in dynamic contrast enhanced (DCE) MRI, and its metabolic features, as seen by Magnetic Resonance Spectroscopy (MRS) or Positron Emission Tomography (PET), result in emergence of definable phenotypes. At the Center for Computational Imaging and Personalized Diagnostics (CCIPD) at Case Western Reserve University, we have been developing computerized knowledge alignment, representation, and fusion tools for integrating and correlating heterogeneous biological data spanning different spatial and temporal scales, modalities, and functionalities. These tools include computerized feature analysis methods for extracting subvisual attributes for characterizing disease appearance and behavior on radiographic (radiomics) and digitized pathology images (pathomics). In this talk I will discuss the development work in CCIPD on new radiomic and pathomic approaches for capturing intra-tumoral heterogeneity and modeling tumor appearance. I will also focus my talk on how these radiomic and pathomic approaches can be applied to predicting disease outcome, recurrence, progression and response to therapy in the context of prostate, brain, rectal, oropharyngeal, and lung cancers. Additionally I will also discuss some recent work on looking at use of pathomics in the context of racial health disparity and creation of more precise and tailored prognostic and response prediction models.

Abstract: Artificial Intelligence In Digital Pathology: A Roadmap To Routine Use In Clinical Practice
Histopathology has undergone major changes, first with the introduction of immunohistochemistry, and latterly with genomic medicine. We argue that a third revolution is underway: artificial intelligence (AI). Coming on the back of digital pathology, the introduction of AI has the potential to both challenge traditional practice and provide a totally new realm for pathology diagnostics. Here, we stress the importance of certified pathologists having learned from the experience of previous revolutions, being willing to accept such disruptive technologies, and being ready to innovate and actively engage in the creation, appl ication and validation of technologies, and oversee the safe introduction of AI into diagnostic practice.
Pathology has experienced the adoption of several major disruptive technologies, beginning with the introduction of immunohistochemistry, and recently with genomic medicine. Suggested to be “the third revolution in pathology”, artificial intelligence (AI) has the potential to challenge the traditional paradigm, especially with regard to routine molecular diagnostic assessment of biomarkers, which can be troublesome and time consuming to evaluate. It is essential that certified pathologists embrace and engage with these disruptive technologies. The advent and adoption of digital pathology is the ideal conduit for the creation and validation of AI applications for diagnostic histopathology practice. The development of robust AI tools requires stringent quality control to rigorous standards. The hybrid nature of our laboratory in the Precision Medicine Centre of Excellence at Queens University Belfast provides an ideal proving ground for AI development, and its application to research and clinical practice. Our state of the art UKAS accredited laboratory houses the Molecular Diagnostic NHS service, compliant to ISO:15189 standards, as well as integrated Genomics, Bioinformatics and Tissue Hybridisation & Digital Pathology groups, where the creation of bespoke AI tools can be generated, tested and applied across a translational environment. We believe our end-to-end workflows; from initial high quality tissue resources, through automated staining and scanning, to specialist pathologist annotation and bespoke deep learning models, represent a stringent roadmap for the generation of AI tools with significant research and clinical applications.

Biography
Yinyin Yuan leads the Computational Pathology and Integrated Genomics team at the Institute of Cancer Research, London. Building on 15 years of experience in machine learning and 10 years in digital pathology, she aims to deliver practical solutions and machine learning innovations for histopathology and genomics.
Her research focuses on the emerging concept that tumours are complex, evolving ecosystems with dynamic crosstalk between cancer and normal cells. By combining computational pathology and genomics, her team collaborates closely with pathologists, clinicians and biologists to understand how cancer cells evolve genetic diversity and drug resistance within the tumour microenvironment.
Abstract: Reproducible AI for digital pathology: From early detection to cancer treatment
One of the fundamental questions in cancer biology is how cancer evolves. Tumours are complex, evolving ecosystems with dynamic crosstalk among cancer and normal cells. Measuring spatial heterogeneity in the tumour microenvironment is a critical first step towards understanding the spatial context in which cancer develops and evolves. I will discuss quantitative spatial histology measures of immune response as a result of deploying machine learning and spatial statistics widely used in ecology. Geospatial variation in the immune microenvironment can have profound clinical implications, both for early diagnosis and in cancers with low immunogenicity, such as estrogen-receptor positive breast cancer. I will also share our recent progress on studying the geospatial complexity of tumour microenvironment in the TRACERx study of lung cancer evolution. Our AI based image-omics techniques to integrate digital pathology and omics data shed light on the genetics that co-evolves with immune ecological environment to drive immune evasion.
