Liquid biopsy in 2016

Circulating tumour cells and cell-free DNA in gastrointestinal cancer

The challenge to obtain needle biopsy samples from patients with cancer has steered the development of new blood-based diagnostics called 'liquid biopsy'. In 2016, major advances have been made in the use of circulating tumour cells and cell-free DNA for monitoring tumour evolution in patients with cancer of the gastrointestinal tract, with a focus on colorectal cancer.
