摘　　要：目的探讨进展期胃癌化疗前后血清巨噬细胞抑制因子-1(MIC-1)水平的变化及其临床意义。方法回顾性分析2013年1月~2015年1月在丽水市中心医院住院的进展期胃癌患者61例,应用酶联免疫吸附测定双抗体夹心法检测其化疗前、化疗2个周期后血清MIC-1水平,采用电化学发光免疫分析仪检测上述胃癌患者血清标本癌胚抗原(CEA)、糖类抗原(CA199)浓度,分析化疗前后血清肿瘤标志物水平的变化与临床资料的关系。结果化疗后MIC-1、CEA、CA199水平均明显低于化疗前,差异均有统计学意义(P<0.05)。MIC-1水平与临床分期及分化程度相关(P<0.05)。MIC-1联合CEA、CA199三者作为一个肿瘤标志物,化疗前其表达与临床分期、分化程度及化疗疗效相关(P<0.05),与腹水高度相关(P<0.01);化疗后其表达与腹水、分化程度、化疗效果均相关(P<0.01)。结论 MIC-1在诊断进展期胃癌方面有较高的研究价值,同时联合CEA、CA199检测可以更好地评价胃癌患者的化疗效果,对于判定胃癌患者预后及预示复发有一定的预测价值。MIC-1作为一种新的肿瘤标志物具有良好的应用前景及研究价值。Objective To investigate the changes and the clinical significance of serum macrophage inhibitory cytokine（MIC-1） levels before and after chemotherapy in advanced gastric cancer. Methods The clinical data of 61 patients with advanced gastric cancer admitted to Lishui Central Hospital from January 2013 to January 2015 were retrospective analyzed. Double antibody sandwich ELISA method was applied to detect the serum MIC-1 levels before chemotherapy and after 2 cycles of chemotherapy. The carcinoembryonic antigen（CEA） and cancer antigen-199（CA199） concentration in serum samples of the gastric cancer were detected by electrochemiluminescence immunoassay analyzer. Relationship between the levels of serum tumor marker before and after chemotherapy and the clinical data were analyzed.Results After chemotherapy, the levels of MIC-1, CEA and CA199 were all significantly lower than those of before chemotherapy, with statistically significant differences（P〈0.05）. The level of MIC-1 was correlated with the clinical stage and the degree of differentiation, with statistically significant differences（P〈0.05）. MIC-1 combined with CEA and CA199 as one tumor marker, before chemotherapy, the expressions were correlated with the clinical stage, the degree of differentiation and the chemotherapy efficacy（P〈0.05）, and was highly correlated with ascites（P〈0.01）. After chemotherapy, the expressions were highly correlated with ascites, differentiation and chemotherapy efficacy（P〈0.01）. Conclusion This study suggests that MIC-1 has high research value in the diagnosis of advanced gastric cancer. MIC-1 combine with CEA and CA199 can better evaluate the chemotherapy efficacy in patients with gastric cancer and has certain prognostic value for determining the prognosis and the occurrence. As a new tumor marker, MIC-1 has good application prospect and research value.
