摘要 目的通过流式细胞仪(FCM)测定胸腔积液脱落细胞细胞核的脱氧核糖核酸(DNA)含量,并将此方法与传统的病理学方法、肿瘤标志物癌胚抗原(CEA)的检测相比较,以鉴别胸腔积液的良、恶性。方法病例选自2005年3月至2009年8月淮安市肿瘤医院的住院患者,留取新鲜的胸腔积液标本,以肝素抗凝,荧光染料染色后,用流式细胞仪检测细胞核DNA倍体,分析细胞的增殖能力。结果根据临床检查将胸腔积液分为良性和恶性两组,在恶性胸腔积液组中,87.5%的标本可以检测到DNA异倍体,在良性胸腔积液中,90%的标本表现为二倍体。结论流式细胞仪DNA倍体测定使得病理诊断有了可依据的客观指标,是病理学检查的有益补充,与CEA联合测定可以提高恶性胸腔积液的检出率。
