Context

 

About 90% of cancer mortality today are associated with metastases. These metastases are due to a small number of circulating tumour cells (CTC), which escape the primary tumour, travel in the blood, and contaminate distant organs in multiple locations. In the process, these CTC often undergo modifications that make them more resistant to treatment than the primary tumours. Being able to characterize and study them would thus be essential for treatment optimization, but so far their rarity (typically one per ml blood) has limited such studies.
