报告简介  Abstract

Statistical learning models have been utilized in analysis of omics based molecular signatures predictive of disease risk and patient outcomes. Harnessing the power of big data and statistical science has brought huge benefit to patients, although the vision of precision medicine and data science is far from realized. I will introduce statistical developments and then three real studies published in the last decade. First is on a 10-year study on patient survival outcome of advanced head and neck cancer after chemotherapy evolving from high dimensional genomic data to a panel of biomarkers predictive of survival. The second case study is to assess clinical outcomes of multiple myeloma patients receiving immunotherapy where none of the biomarkers are predictive of progression survival but it is how the immune-response change over time that is predictive of patient outcome utilizing a sophisticated functional model. The last one is to predict the risk of developing Alzheimer early using metabolomics analysis. Statistical learning algorithms have played an important role in these studies. To realize the potential of current experimental and real world data, greater collaboration among researchers from multiple disciplines is necessary. (This work is a collaboration of biologists, physicians and biostatisticians and bioinformaticians)
