Outline of Final Research Achievements |
The “CellSearch” is widely used to detect circulating tumor cells (CTCs), but provided only modest sensitivity in capturing CTCs in lung cancer patients. In the current study, we employed a variety of CTC-detection systems including a novel microfluidic device (“CTC-chip”) in which any antibody to capture CTCs is easily conjugated. In experimental studies using tumor cell lines, the “CTC-chip” provided a similar efficiency to the “CellSearch” in capturing PC-9 cells with EpCAM expression. When MESO-4 cells without EpCAM expression were spiked in the blood, approximately 80% of tumor cells were captured with the “CTC-chip”, whereas few tumor cells were captured with the “CellSearch”.
