Method The serum of 9 advance lung cancer were collected before application of Gefitinib, and by SELDI-TOF-MS(surface-enhanced laser desorption/ionization time-of-flight mass spectrometry) technique and CM10 proteinchip, these serum proteomic fingerprints were memorized. According to the Response Evaluation Criteria In Solid Tumor(WHO,1979), 9 patients who had took Gefitinib for 1 month were divided into 2 groups, efficacy group(4 cases, CR+PR) and inefficacy group(5 cases , SD+PD). The detected data were analyzed by Biomarker Wizard Software. Results The
