Method for screening early-stage lung tumor in assisting mode through bronchoalveolar lavage fluid

Abstract

The invention relates to a method for screening early-stage lung tumor in an assisting mode through bronchoalveolar lavage fluid. Prior-art constraints of conventional lung outside sampling specimens and operation sampling lung specimens are broken through, normal saline is poured into the lung of a patient through a fiber bronchoscope and drawn out to form the bronchoalveolar lavage fluid, M2-PK monoclonal antibodies and second M2-PK antibodies are added, and the concentration of M2-PK in the bronchoalveolar lavage fluid is measured with the enzyme-linked immunosorbent assay method and compared with a critical value 18.68 U / ml; as the fiber bronchoscope can go deep into the lung of the patient, the bronchoalveolar lavage fluid is formed in the mode that alveolus pulmonis of the patient is directly washed and comprises alveolus pulmonis secreta, the lesion characteristics of the lung of the patient can be most reflected, the bronchoalveolar lavage fluid serves as an assistant judgment basis of the early-stage lung tumor, screening of the early-stage lung tumor is more accurate, and in addition, operation is not required, trauma is not generated, the method is safer and more reliable, and cost is also low.

Description

technical field [0001] The invention relates to a medical detection method, in particular to a method for assisting screening of early lung tumors by using alveolar lavage fluid. Background technique [0002] The large group of smokers and laborers who work in harsh air environment for a long time are mostly suspicious objects of lung tumors. However, the diagnosis of lung tumors is difficult at present. If patients are not diagnosed and treated in time, they will continue to deteriorate , and even life-threatening serious consequences. [0003] At present, various methods for early lung tumor screening have considerable limitations. [0004] For example, although cytological examination of pleural effusion exfoliation is the simplest and most specific examination method, its positive rate is low, and many cases with cytological examination of pleural effusion are often misjudged as suspicious for malignancy. [0005] Another example is that the positive rate of percutaneo...

Problems solved by technology

[0006] In recent years, medical thoracoscopy has been carried out more and more. Although its diagnostic efficiency is relatively high, many primary hospitals currently do not have this technology. Compared with routine examinations, the examination costs are high and traumatic. It is not suitable for patients with weak constitution, thus limiting its popularization and application

[0007] To sum up, the current screening methods for early lung tumors are not accurate enough. Some methods are relatively accurate, but they are expensive and traumatic, and are not suitable for patients with weak constitutions.
