Abstract
目的 探讨胸水沉渣包埋联合免疫组化方法在胸水转移性肺腺癌和胸膜恶性间皮瘤诊断及鉴别诊断中的应用价值.方法 采用常规细胞涂片法和沉渣包埋联合免疫组化法对比62例患者胸水,免疫组化选用CEA、TTF-1、mesothelial cell(MC)、calretinin(C R)、vimentin、AE1/AE3和CK7抗体进行染色.结果 常规涂片法诊断:转移性腺癌39例、恶性肿瘤细胞7例、可疑癌瘤细胞16例;沉渣包埋联合免疫组化法诊断:转移性腺癌54例、恶性间皮瘤8例.免疫组化示转移性腺癌CEA(81.5%)和TTF-1(81.5%)(+);恶性间皮瘤MC (87.5%)、CR(100%)和vimentin(100%)(+).结论 沉渣包埋联合免疫组化法在胸水转移性肺腺癌和胸膜恶性间皮瘤病理诊断分型方面明显优于常规细胞涂片法;CEA、TTF-1、MC、CR和vimentin抗体组合检测对胸水转移性肺腺癌与胸膜恶性间皮瘤的鉴别诊断具有重要意义.
