The 11th International Conference on Biomedical Engineering and Biotechnology (ICBEB 2022)

Abstract: Since the inception of virtual microscopy in the 1990's, histology image analysis has migrated from optical microscope to visual inspection over digital histological images that were scanned and generated at high resolution. Detection of cancer and estimation of its prognosis are tedious process from the digital whole slide images because of its sheer area and complexity. Recently, by the efforts of multi-disciplinary research, artificial intelligence methods especially computer vision, object recognition, deep learning and XAI have become popular aids to grading and staging of cancer diagnoses and prognosis, by automatically analyzing over digital histopathology images. It was claimed that AI has helped pathologists to lower down the assessment errors by magnitude. Most of the research literature reports about identifying the cell types, segmenting the tumour and the cells. Current trend has it that the recognition of cells is done by deep learning due to its effectiveness in learning the features of the cells and recognizing them by their features. However, the accuracy and certainty of those histological deep learning methods are bottle-necked at the image level. Recognition rate is never perfect from solely the images. Lately it is discovered that the tumour immune microenvironment (TME) consists of many heterogeneous cell types that engage in extensive crosstalk among the cancer, immune and stroma tissues. In addition to just the cell types, the spatial organization of these different cell types in TME are observed as biomarkers for predicting metastasis, prognosis and drug responses via scRNAseq and spatial transcriptomics technologies. It opens up a new arena where AI can extend its power in analyzing the localization of cells, types of cells and their interactions, as a whole for further improving the prediction accuracy. In this talk, we will narrate the brief history, the current practices and future prospect of applications of AI on histological image analysis. This speech puts the future of AI research over histological images into a perspective that extra dimensions of analysis are in need for inferring more insights from histological image analysis. Novel models in this perspective are introduced. Future opportunities by integrating digital histopathology images with molecular omic data, spatial information, as well as meta-level analysis will be discussed for better understanding of a tumour ecosystem. During the keynote speech, our lab principal researcher, Dr. Gloria Li, will demonstrate several deep learning applications which are the cornerstone AI techniques over histopathological image analysis.
