摘要 目的:探讨DNA倍体分析在宫颈病变筛查中的作用。方法:选取2012年在无锡妇幼保健院同时行DNA倍体分析及液基薄层制片检查(TCT)的1 179例进行数据分析,其中122例进行病理活检。结果:在TCT为正常、炎性改变、非典型鳞状上皮(ASCUS)、低度病变(LSIL)、高度病变(HSIL)及鳞状细胞癌(SCC)中,对应的DNA倍体阳性率分别为3.7%、25.5%、81.0%、91.3%、100%。以病理活检结果为金标准,DNA倍体分析ROC曲线下面积(0.879)大于TCT ROC曲线下面积(0.799),DNA倍体分析及TCT的敏感性分别为89.4%和68.4%,特异性分别为76.2%和85.7%,阳性预测值分别为63.0%和68.4%,阴性预测值分别为94.1%和85.7%,其中敏感性差异有统计学意义(P<0.05)。对于少量DNA倍体异常细胞,联合TCT结果可以提高诊断的准确性。结论 :DNA倍体分析是一种有效的宫颈病变筛查方法。
