Here’s our @Nature paper on v deep whole-genome sequencing of serial ctDNA and met tissue. @cherberts1, Matti, Joonatan et al applied new methods to give fascinating insight into temporal #ProstateCancer clonal complexity and evolution of resistance. 1/7 nature.com/articles/s4158… Image ctDNA is a composite of distinct cancer populations, with small contributions to total ctDNA from each metastasis. Intra-patient clones are typically similar but can exhibit startling differences in key features such as whole-genome doubling status or mutational signatures. 2/7 ImageImage
