Due to a variety of environmental changes, including aging, health threat relevant to lung cancer and death may also be will increase.Root According to cytology and origin of cell, lung cancer can be divided into multiple subspecies classes.Main Types include non-small cell carcinoma (NSCLC) and Small cell carcinoma (SCLC).
Although radiology, surgery and chemotherapy obtain progress, 5 years survival rates of Past 30 Years lung cancer do not have substantially It changes, only 15% patient 5-year Survival or 5 years or more after initial diagnosis.These low survival rates mainly by The diagnosis of early stage is hampered in some simultaneous illnesss, limits the effect of therapy intervention.
Current small throughput diagnostic method includes sputum smear, chest x-ray and CT scan.These methods are only when patient has Characteristic symptom, such as long-term cough, spit, hemoptysis, uncomfortable, pain or loss of weight, and hospital is gone to just to use when seeing the doctor, Thus these methods are not appropriate for carrying out high flux examination to a large amount of crowds.In addition, these methods false positive with higher, it must Subsequent invasive means, such as bronchoscope or tissue biopsy must be cooperated, made a definite diagnosis.Cytology detection is based on cell shape State, structure and anatomy, can be used hematoxylin and eosin dyeing is handled.The means are widely used in medical diagnosis, And by the gold standard as screening for cancer biopsy.Then hematoxylin uses the solution counterstain of eosin Y, daybreak to nuclear targeting Red Y is dyed to cytoplasm fraction, generally includes intracellular and extracellular protein.The colouring method can be used for critical tumorogenic egg White in-site detecting;Such as epithelial growth factor receptor (EGFR), Cyclin D1 or K-Kas.Anticancer egg is directed to these The relevant ligase of white antibody, such as horseradish peroxidase (HRP) or alkaline phosphatase (AP) or fluorescent dye such as fluorescein It can be used for finding the amount or cell position of any oncogene in biopsy.Similarly, using tumor inhibitor antibody, such as p53 Or Retinoblastoma Protein (pRB), it can be used for finding the cell position of weak sign or change;Such methods can mention A possibility that showing canceration is increasing.Although such methods comparative maturity, speed are slower, it is impossible to be used in extensive high-throughput sieve It looks into.
Many methods wish to more effectively diagnosing.For example, for the nucleic acid that can encode albumen, using specific Primer or probe carry out diagnosing, and numerical value is believed to state (i.e. phosphatidylinositols-glycan specificity of instruction lung cancer Phospholipase D;GPLD1).However, it is this use albumen as the method for pulmonary cancer diagnosis biomarker there are no commercialized elder generations Example.It is any to be difficult to detect early stage using the method that blood is detected since the early stage of lung cancer is scattered in the different location of lung Lung cancer because blood usually reflect be the entire circulatory system situation.Therefore, it is necessary to research and develop a kind of inexpensive and effective side Method is used for quick diagnosis, and is easy to be commonly used.
In view of this, the present invention is specifically proposed.
