| Outline of Final Research Achievements |
Prognosis of primary lung cancer patients is not satisfactory, which is mostly caused by frequent development of distant metastasis. Although Circulating Tumor Cell (CTC) is useful for a surrogate marker of distant micro-metastasis, the CellSearch which is the only machine for CTC detection for clinical use, is insufficient sensitivity. Therefore, we developed a new microfluidic chip system of domestic, to improve sensitivity, and evaluated its basic performance. Newly developed CTC-chip not only EpCAM that have been targeted up to now showed good capture ability for other cell surface antigens. In addition, it was possible genetic analysis of the captured cells.
