ABSTRACT
Objective To identify new serum biomarkers of lung adenocarcinoma.Methods Serum samples from 31 patients with lung adenocarcinoma and 31 healthy individuals were applied to SAX-2 protein chips to generate proteomic spectra by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry(SELDI-TOF-MS).The spectra were analyzed with Ciphergen Biosystems software and biomarker patterns software.Results The software identified 102 peaks and m/z 14 022.9 and 3 735.99 were used to construct the classification tree.The classification tree separated adenocarcinoma of lung effectively from healthy individuals,achieving a validity of 100%.The blind test challenged the model with a sensitivity of 100%and a specificity of 100%.Conclusions The results suggest that SELDI-TOF-MS technique can distinguish lung adenocarcinoma patients from healthy individuals and shows great potential for the development of a screening test for the detection of lung cancer.
