摘要 目的研究癌胚抗原(CEA)、肝素酶(Hpa)、多巴脱羧酶(DDC)、基质金属蛋白酶7(MMP-7)、磷酸丝氨酸磷脂酶(PSPH)与胃癌早期转移之间的关系。方法利用RT-PCR检测方法对80例胃癌患者及16例胃良性病变患者及20例健康体检者的血清进行检测,检测胃癌患者外周血中CEA mRNA、Hpa mRNA、DDC mRNA、MMP-7 mRNA、PSPH mRNA的表达。结果胃癌组较胃良性瘤组及健康组外周血CEA mRNA、Hpa mR-NA、DDC mRNA、MMP-7 mRNA、PSPH mRNA表达阳性率明显增高(P<0.05);在胃癌组中,五种标志物阳性率中CEA mRNA最高,差异有统计学意义(P<0.05);胃癌组CEA mRNA、Hpa mRNA、DDC mRNA、MMP-7 mRNA、PSPH mRNA这五种指标在肿瘤部位、临床分期、组织学类型、pTNM、淋巴结转移及肝转移间阳性率比较均有统计学差异(P<0.05);随着临床分期的增加,这些肿瘤标志物的表达率也明显升高。结论胃癌患者外周血中存在CEA mRNA、Hpa mRNA、DDC mRNA、MMP-7 mRNA、PSPH mRNA表达,CEA mRNA阳性率最高,该五项指标能预测外周血微转移和判断预后。
