Core Tip

Core tip: The potent utilities of circulating tumor cells and cell-free nucleic acids have recently attracted attention toward their clinical application in therapeutic management of cancer patients. The concept of “liquid biopsy” can allow for repeated samplings and real-time monitoring of tumor dynamics in each individual patient and consequently would facilitate the development of “tailor-made” cancer management programs. Before translating this novel diagnostic and prognostic assay into the clinical settings, further large-scale studies with well-established methods are required to validate its clinical relevance.
