    Improvements in genomic and molecular methods are expanding the range of potential applications for circulating tumour DNA (ctDNA), both in a research setting and as a ‘liquid biopsy’ for cancer management. Proof-of-principle studies have demonstrated the translational potential of ctDNA for prognostication, molecular profiling and monitoring. The field is now in an exciting transitional period in which ctDNA analysis is beginning to be applied clinically, although there is still much to learn about the biology of cell-free DNA. This is an opportune time to appraise potential approaches to ctDNA analysis, and to consider their applications in personalized oncology and in cancer research.We would like to acknowledge the support of The University of Cambridge, Cancer Research UK (grant numbers A11906, A20240, A15601) (to N.R., J.D.B.), the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013)/ERC Grant Agreement n. 337905 (to N.R.), the Cambridge Experimental Cancer Medicine Centre, and Hutchison Whampoa Limited (to N.R.), AstraZeneca (to R.B., S.P.), the Cambridge Experimental Cancer Medicine Centre (ECMC) (to R.B., S.P.), and NIHR Biomedical Research Centre (BRC) (to R.B., S.P.).

    International audienceColorectal cancer is one of the leading cause of death by cancer worldwide in both men and women. Liquid biopsy belongs nowadays to the landscape of cancer management biological tools. In this chapter, we will describe and discuss the actual, potential and future applications of cfDNA analysis in plasma of patients with colorectal cancer in early or metastatic stage. During the last decade, the development of molecular biology assays like digital PCR or next-generation sequencing made the analysis of cfDNA in plasma possible with an excellent sensitivity and applications like early detection, diagnosis, prognosis, response to treatment, monitoring of an emerging resistance, mapping of the disease molecular landscape or evaluation of the residual disease are now feasible. cfDNA detection has several promising applications in the management of patients with colorectal cancer, but prospective randomised clinical trials are still lacking to make liquid biopsy ready for prime-time
