Analysis of circulating tumour components using liquid biopsy approaches holds considerable promise to improve the detection and treatment of cancer. In this Review, Alberto Bardelli and colleagues outline how different forms of liquid biopsy, and particularly the assessment of circulating tumour DNA, can be exploited to guide patient care, and discuss the progress made to date in integrating such analyses into the clinic.
