New paper on detecting and quantifying subclonal selection in cancer sequencing data by CDB's Marc Williams and Chris Barnes
30 May 2018
Tumour growth is an evolutionary process.
This work, published in Nature Genetics by Marc Williams and Chris Barnes, and in collaboration with Andrea Sottoriva (Institute of Cancer Research) and Trevor Graham (Barts Cancer Institute), describes a new mathematical modelling approach to understand DNA sequence data from human cancer biopsies. Combining simple mathematical models of growing populations and Bayesian statistics, the authors are able to infer how a tumour has evolved and for the first time quantify important aspects of the dynamics including mutation rate and fitness changes. In the long-term, such models could be used to predict a tumour's future growth within a patient and guide therapeutic strategies.
