摘　　要：Background： Increased level of serum macrophage inhibitory cytokine- 1 （MIC- 1 ）, a member oftransfonning growth thctor-β superfamily, was found in patients with epithelial tumors. This study aimed to evaluate whether serum level of MIC-I can be a candidate diagnostic and prognostic indicator for early-stage nonsmall cell lung cancer （NSCLC）. Methods： A prospective study enrolled 152 patients with Stage I-II NSCLC, who were followed up after surgical resection. Forty-eight patients with benign pulmonary disease （BPD） and 105 healthy controls were also included in the study. Serum M IC- 1 levels were measured using an enzyme-linked immunosorbent assay, and the association with clinical and prognostic features was analyzed. Results： In patients with NSCLC, serum protein levels of M IC-I were significantly increased compared with healthy controls and BPD patients （all P 〈 0.001 ）. A threshold of 1000 pg/ml ofM IC-1 was found in patients with early-stage （Stage 1 and II） NSCLC, with sensitivity and specificity of 70.4% and 99.0%, respectively. The serum levels ofMIC- ] were associated with age （P = 0.001 ）, gender （P = 0.030）, and T stage （P = 0.022）. Serum MIC-1 threshold of 1465 pg/ml was found in patients with poor early outcome, with sensitivity and specificity of 72.2% and 66.1%, respectively. The overall 3-year survival rate of NSCLC patients with high serum levels of MIC-1 （〉I 465 pg/ml） was lower than that of NSCLC patients with low serum MIC-1 levels （77.6% vs. 94.8%）. Multivariate Cox regression survival analysis showed that a high serum level ofMIC- 1 was an independent risk factor lbr reduced overall survival （hazard ratio - 3.37, 95% confidential interval： 1.09-10.42, P = 0.035）. Conclusion： The present study suggested that serum M1C-I may be a potential diagnostic and prognostic biomarker ~cbr patients with early-stage NSCLC.Background： Increased level of serum macrophage inhibitory cytokine- 1 （MIC- 1 ）, a member oftransfonning growth thctor-β superfamily, was found in patients with epithelial tumors.
