| 摘 要： | 目的探讨联合检测细胞表面黏附分子(CD44v6)和癌胚抗原信使核糖核酸(CEA-mRNA)在恶性胸腔积液鉴别诊断中的应用价值。方法选取90例胸腔积液患者,其中良性疾病组患者39例,恶性疾病组患者51例。采用ELISA法检测胸腔积液CD44v6含量,荧光定量聚合酶链反应(FQ-PCR)方法检测恶性胸腔积液CEA-mRNA,并比较这两种物质在良、恶性胸腔积液中的阳性率。结果 CD44v6和CEA-mRNA在恶性胸腔积液组中阳性率明显高于良性胸腔积液组,联合检测敏感性和特异性高于单项检测。结论 CD44v6被认为是肿瘤的特征性和早期指标,与肿瘤的生长、侵袭和转移有关;CEA-mRNA几乎只存在于某些肿瘤细胞内,细胞之外不能存在游离的CEA-mRNA,在胸腔积液内检测到CEA-mRNA,提示胸腔内发生了能表达CEA-mRNA的肿瘤细胞的胸腔转移。两者联合检测,对于诊断和鉴别胸腔积液的性质有重要的临床意义。
