Circulating tumor cells: Blood-based detection, molecular biology, and clinical applications
31 Jul 2025
Abstract excerpt
Circulating tumor cells (CTCs) are cancer cells, shed from primary tumors or metastases into the bloodstream. The first non-invasive "liquid biopsy" for cancer monitoring, CTCs have been largely surpassed by circulating tumor DNA (ctDNA) for clinical applications, given the ease of DNA sequencing without specialized cell isolation methods. However, emerging rare cell capture technologies that can process larger...
