Abstract: 【Abstract】ObjectiveTo detect the expression levels of multiple serum chemokines including IFNinducible T cell chemoattractant (ITAC), Fractalkine, macrophage inflammatory protein(MIP)3α, IL8, MIP1α, MIP1β in patients with lung cancer and explore their association with the clinical characteristics of lung cancer as well as the correlations among these chemokines. MethodsForty newly diagnosed patients with lung cancer and thirty healthy controls were enrolled for detection of the serum levels of 6 kinds of chemokines by Luminex technology. The correlations of clinical characteristics of lung cancer with these chemokines and the correlations among these chemokines were analyzed by SPSS 17.0 software. ResultsThe serum levels [M(QR)] of IL8, Fractalkine and MIP3α in patients with lung cancer were 5.16(4.74), 128.45(141.89), 10.31(8.88) respectively, and 2.01(0.95), 61.46(74.81), 8.08(5.87) respectively in control group, with significant differences (Z=-4.783, P<0.001; Z=-4.046, P<0.001; Z=-3.105, P=0.002). The expression of MIP1β in lung adenocarcinoma was significantly higher than that in squamous carcinoma [18.32(12.27) vs. 13.72(7.31), Z=-2.212, P=0.027], and of ITAC in squamous carcinoma was significantly higher than that in small cell lung cancer [24.51(22.48) vs. 9.28(4.85), Z=-2.460, P=0.014]. The expressions of MIP3α and Fractalkine were positively correlated in the two groups (r=0.619, P<0.001; r=0.766, P<0.001). ConclusionThe expressions of IL8, Fractalkine and MIP3α increase significantly in lung cancer patients, and they are may play important roles in metastatic lung cancer.
