摘要 目的探讨免疫细胞化学和形态学分析在胸腹水细胞学鉴别诊断中的意义。方法选取河北北方学院附属第一医院消化内科,呼吸内科的良、恶性胸腹水患者各30例,应用免疫细胞化学SP法检测癌胚抗原(CEA)、上皮膜抗原(EMA)、波形蛋白的表达,同时应用计算机图像分析系统定量测定其脱落细胞的核面积、质面积、核质比、细胞周长、平均直径、圆度和形状因子。结果 1恶性胸腹水中腺癌细胞(B组)CEA表达均阳性,EMA部分阳性,波形蛋白均阴性;增生性间皮细胞(A组)EMA和波形蛋白部分阳性,CEA均阴性。CEA单独诊断的敏感性、特异性、阳性预测值、阴性预测值均最好,联合检测EMA+波形蛋白组合的敏感性和特异性较好。2良恶性标本的细胞形态学测量结果显示:良性组标本的面积、周长等效直径、长径、短径与恶性标本间存在明显差异,良性组明显低于恶性组(P<0.05);变异系数在两组间比较显示良性组标本的面积、周长等效直径、长径、短径与恶性标本间存在明显差异,良性组明显低于恶性组(P<0.05)。结论 1免疫细胞化学在良恶性胸腹水鉴别诊断中有重要作用,CEA单独诊断以及EMA+波形蛋白联合检测均可获得较好的敏感性、特异性;2形态学定量分析可为鉴别诊断提供参考,二者综合分析是提高胸腹水细胞学阳性诊断率的有效途径之一。
