Dr. Jacky Lam is the Assistant Professor of the Department of Chemical Pathology and an honorary associate consultant at the Prince of Wales Hospital. Dr. Lam obtained his medical degree in 2007 and received his Ph.D. in Chemical Pathology from the Chinese University of Hong Kong in 2020. His research interests are on the biological features of plasma DNA and its potential clinical application in noninvasive cancer detection. He is involved in a large-scale prospective clinical study using plasma Epstein-Barr virus DNA for screening of nasopharyngeal carcinoma. This study laid the foundation for the clinical utility of plasma Epstein-Barr virus DNA analysis for cancer screening. Based on this study, he has further investigated the distinct molecular features of plasma Epstein-Barr virus DNA in nasopharyngeal cancer. Such discoveries have led to the development of novel diagnostic assays which allows better differentiation of patients with nasopharyngeal cancer and non-cancer subjects in the context of screening.
