The invention relates to the technical field of medical diagnostics, in particular to the field of tumor diagnosis. By analyzing the concentration of small-molecule metabolites in blood of a normal person, blood of a person before a lung cancer operation is carried out, and blood of a person after the lung cancer operation is carried out, multiple metabolism markers which can be used for monitoring the lung cancer curative effect and multiple metabolism markers which can be used for lung cancer diagnosis are screened out. The method has the advantages of being high in sensitivity and flux, and applicable to lung cancer screening and auxiliary diagnosis. |
