摘要 目的:评价细胞DNA定量分析及液基细胞学两种检查方法对宫颈病变筛查的诊断价值。方法:通过对门诊6 793例妇女用宫颈刷取材,液基薄层制片2张,1张进行巴氏染色作TBS诊断,另1张进行Feulegn染色,并经全自动DNA图像分析系统做DNA倍体分析,以病理结果为金标准,比较两种方法阳性检出率、敏感性及特异性。结果:液基细胞学阳性检出率9.48%,显著低于DNA定量分析阳性检出率12.95%(P<0.05);宫颈检出液细胞和(或)DNA定量检测阳性者宫颈活检共1 043例,病理证实CIN1及其以上级别病变共183例中,以少量DNA倍体异常细胞作为活检标准,DNA定量分析方法敏感性97.81%,特异性为18.49%;以中量DNA倍体异常细胞作为活检标准,则该方法的敏感性89.62%,特异性为84.19%;若以LSIL作为活检标准,液基细胞学方法筛查敏感性72.13%,特异性90.47%。结论:DNA定量分析法和液基细胞学方法均可早期、有效筛查宫颈癌及癌前病变,DNA定量分析法较液基细胞学方法灵敏度高,但特异性则低于液基细胞学方法,故两者结合可更有利于宫颈病变的筛查和诊断,可有效提高诊断高级别宫颈上皮内瘤变和宫颈癌的敏感性和特异性。
