Circulating tumour cells (CTCs) might be representative of the tumour burden and might also provide information on tumour cell biology. As such, these cells hold promise in the prediction and monitoring of response to anticancer therapy. In this Review, the authors highlight the challenges of monitoring treatment response in metastatic castrate-resistance prostate cancer and discuss the developments in CTC analyses that have increased the value of these cells as potential biomarkers in this disease.
