摘要 [目的]探讨胃癌患者血清中Dickkopf-1(DKK1)的表达及其临床意义。[方法]酶联免疫吸附夹心法和化学发光免疫法分别检测160例胃癌患者术前血清DKK1、CA19-9、CEA水平,以及52例胃良性疾病患者和40名正常体检者的DKK1水平,并观察其中123例患者根治术后血清DKK1变化。[结果]胃癌患者血清DKK1水平[(5.89±1.77)ng/ml]明显高于健康体检组[(3.18±1.12)ng/ml](Р<0.0001)和胃良性疾病组[(3.57±1.05)ng/ml](Р<0.0001);分层分析发现,随着疾病的进展,血清DKK1水平逐渐升高,Ⅲ期和Ⅳ期血清DKK1水平均高于Ⅰ期(Р<0.001),有淋巴结转移及肝脏转移者的血清DDK1水平升高更为明显(Р=0.006、0.028)。根治术后血清DKK1水平[(4.21±1.27)ng/ml]比术前[(5.64±1.56)ng/ml]明显降低(Р<0.001)。此外,血清DKK1水平对胃癌诊断的灵敏度和准确率均高于CA19-9和CEA。[结论]胃癌患者血清DKK1水平明显高于健康体检组和胃良性疾病组,且血清DKK1的表达水平与胃癌患者的TNM分期以及淋巴结转移、肝脏转移有关。血清DKK1表达水平可作为反映胃癌生物学行为和术后随访、监测的参考指标。
