Description of the Invention: [Technical Field of the Invention] The present invention relates to a kit and method for capturing tumor cells in a body fluid sample or a + a serum sample. In particular, the kits and methods of the invention are used to capture circulating tumor cells. [Prior Art] Cancer is the result of cumulative multi-gene mutations that inactivate carcinogenic genes and/or inactivated money. Cancer remains the global mortality rate = the main reason. Despite advances in diagnosis and treatment, overall survival has not improved significantly over the past several years. There is still a need to achieve more (4) tumor diagnosis methods. Most cancer deaths are not due to primary tumors. In fact, death is caused by metastasis (i.e., multiple widely distributed tumor groups, from malignant cells that are detached from the original tumor site and often travel through the body to the distal site:). If a primary tumor is detected as early as possible, surgery, Korean injection, chemotherapy, or some combination of these treatments can often be eliminated. What is embarrassing is that the transfer of group materials is difficult to detect and eliminate, and it is impossible to successfully treat all transfer groups. Because of &, the clinical point of view ^, the decisive factor in the progression of cancer. In addition, the metastatic ability is a property that can be used to catalyze evil and sexual tumors. Cancer metastasis includes the following - a series of complex continuous events: 1. Expanding from the primary site to the surrounding tissue; 2. Penetrating into the body cavity and blood vessels; 3. Release the tumor cells to the distal site via the circulatory system; 4 • Re-invade the tissue at the stagnant site; 纟, 5 adapt to the new environment to promote tumor cell survival, angiogenesis and tumor growth. Based on the complexity of cancer and cancer metastasis and the frustrations in treating cancer patients over the years, there have been numerous attempts to develop detection tests for the development of metastasis and early relapse. Circulating tumor cells (CTCs) are cancer cells that are detached from a primary tumor or a metastases circulating in peripheral blood. Although metastasis is the direct cause of death for most cancers, CTC can constitute the cause of the metastasis and can indicate the extent of the disease. When CTC is extremely rare (per milliliter to most CTCs), identifying CTCs can indicate cancer, or even indicate precancerous growth before significant clinical symptoms appear. The potential for LTC detection in peripheral blood has been shown for the first time more than a century ago, but then it has subsided because the number of CTCs in the sample is extremely small, so it is difficult to detect by conventional methods. The challenge for identifying and characterizing rare tumor cells circulating in the blood is to develop a method that combines high sensitivity with high specificity to distinguish tumor cells from normal epithelial cells and white blood cells. Circulating tumor cell detection can contribute to cancer prognosis, diagnosis of minimal residual disease, sensitivity assessment of tumor anticancer drugs, and personalization of anticancer therapies. The high sensitivity and specificity of CTC can also be applied to the early diagnosis and screening of invasive cancers. Molecular techniques for PCR-based amplification of tumor-specific abnormalities based on DNA or RNA have contributed to the detection of concealed (hidden) tumor cells. PCR-based assays capable of detecting tumor cells in a conventional manner in one million normal cells have been developed to identify circulating tumor cells in various types of cancer. For example, Smith B. et al. developed a reverse transcriptase-polymerase chain reaction to detect melanoma cells in peripheral blood (Lancet, 338. 1236 14li593.doc 201122479). However, the method can effectively activate tumor cells. Because of the cell, I expanded ~ ^ Μ - ^/r Μ - during the extraction, it was destroyed, so this method jj and magnetic · 5 * m 忐 hindered the analysis of cell morphology and phenotype, in detail, it may not be possible The difference between the material that is directly detached from the hang, and the material that is directly detached from the tumor, is also detected by the method of the helmet f+ ...' 丌..., the method detects some related changes in the same cell. Immunofluorescence microscopy can be used to analyze the cell morphology and to directly identify the tumor cells that can be identified by using the appropriate antibody to immunolabel the cells (4). However, since there have been no antibodies against tumors so far, (iv) has been given antigens to (4) CTCs. In addition, the detection of CTC clusters in patients with colorectal cancer has also been developed and evaluated for immunomagnetic cell separation using immunocytochemical markers (Clinical Cancer earch, 2001, Vol. 7, No. 4〇8〇_4〇) 85 pages). W0 2006050352 provides a cell separation device with an improved cell adhesion matrix ("CAMj") and an improved isolated stem cell (such as tumor cells, cells, cells, and angiogenic cells from blood or other tissue fluid samples) Furthermore, WO 2009051734 discloses a device for capturing circulating, non-hematopoietic tumor cells comprising a microfluidic channel bound to a tumor-specific binding agent and a continuous, unidirectional shear stress of 0.1 to 20 dyn/cm 2 in the channel. However, none of the above techniques are effective in detecting CTCs. It is apparent that, especially in the early stages of cancer, there is a great need for a method for identifying cells that have metastatic potential in circulation prior to secondary tumor formation and/or [Invention] 145593.doc 201122479 An object of the present invention is to provide a method for capturing tumor cells in a body fluid sample or a serum-containing sample, comprising the steps of: (a) endothelium-like cells Or epithelium-like cells attached to a solid support; (b) induced with one or more inflammatory inducing agents (a) (c) attaching a white blood cell to the cell of (a); and (d) adding a body fluid sample or a serum-containing sample to the solid support, thereby using 'white ball and endothelial-like cells or epithelial-like cells The cell captures a tumor cell sample or a tumor cell contained in a serum-containing sample.
