摘要 目的探讨富半胱氨酸(Cyr)61、纤溶酶原激活物抑制剂(PAI)-1、miR-155对老年子宫内膜癌(EC)诊断及评估复发的应用价值。方法老年EC患者108例作为观察组,另选取同期子宫内膜增生患者105例作为对照1组,健康体检者105例作为对照2组。比较3组、不同临床特征患者血清Cyr61、PAI-1、miR-155水平,评价各指标对老年子宫内膜良恶性病变的鉴别诊断价值及与临床特征的关系。随访1年,统计老年EC患者复发情况,比较复发与未复发患者血清Cyr61、PAI-1、miR-155及肿瘤标志物[糖类抗原(CA)125、癌胚抗原(CEA)、CA199]水平,分析各指标与肿瘤标志物及复发相关性。结果观察组血清Cyr61、PAI-1、miR-155水平显著高于对照1组、对照2组(P<0.05);受试者工作特征(ROC)曲线分析,血清Cyr61、PAI-1、miR-155联合诊断曲线下面积(AUC)为0.898,95%CI为0.850~0.936,P<0.001,诊断敏感度为77.78%,特异度为84.76%,明显优于三者单独诊断;不同临床分期、分化程度、肌层浸润、有无淋巴结转移患者血清Cyr61、PAI-1、miR-155水平相比,差异有统计学意义(P<0.05);Spearman相关性分析,血清Cyr61、PAI-1、miR-155与临床分期、肌层浸润、淋巴结转移呈正相关,与分化程度呈负相关(P<0.05);随访1年,复发患者血清Cyr61、PAI-1、miR-155水平显著高于未复发患者,CA125、CEA、CA199显著高于未复发患者(P<0.05);Pearson相关性分析,血清Cyr61、PAI-1、miR-155与CA125、CEA、CA199呈正相关(P<0.05);多元线性逐步回归分析,将肿瘤标志物、临床分期、分化程度、肌层浸润、淋巴结转移等其他因素控制后,血清Cyr61、PAI-1、miR-155仍与复发显著相关(P<0.05)。结论血清Cyr61、PAI-1、miR-155联合检测对老年EC具有可靠辅助诊断价值,且与临床分期、肌层浸润、淋巴结转移、分化程度及肿瘤标志物密切相关,还有助于为临床评估复发提供参考依据。
