The invention provides a biomolecular marker and
system for diagnosing non-
small cell lung cancer and application of the biomolecular marker and
system, and belongs to the field of
biomedicine. Related samples of non-
small cell lung cancer patients, populations with
lung benign diseases and healthy populations are analyzed through
proteomics, and eight biomarkers capable of predicting whether a detected object suffers from the non-
small cell lung cancer or not are found; combining the new markers, and further screening to obtain a combination which has the most accurate prediction result and contains five biomarkers; then, on the basis of the marker combination, a
machine learning method is used for developing an optimization model formula, and the
disease risk of a predicted patient is obtained through calculation, so that the non-small
cell lung cancer is conveniently and efficiently diagnosed, a golden
window period of intervention is mastered for high-risk people, the economic burden is relieved for low-risk patients, and clinical requirements are met.
