摘要 目的 探讨HPV E6/E7 mRNA与高危型孔头瘤病毒(HR-HPV) DNA在宫颈病变筛查中的应用价值.方法 对301例宫颈病变疑似病例进行宫颈脱落细胞取样,分别检测慢性宫颈炎、宫颈癌前病变、宫颈鳞状细胞癌中HPV E6/E7 mRNA与HR-HPV DNA的表达,比较二者在不同年龄组及病变程度中表达的差异.结果 在宫颈癌前病变及宫颈鳞状细胞癌患者中HPV E6/E7 mRNA的特异性和阳性预测值高于HR-HPV DNA(P均<0.05),敏感性低于HR-HPV DNA(P <0.05).30岁以下与30~39岁受检者中HPV E6/E7 mRNA的阳性率低于HR-HPV DNA(P均<0.05).CIN2、CIN3及宫颈癌患者HPV E6/E7 mRNA阳性率高于慢性宫颈炎患者,且CIN3者高于CIN2者(P均<0.05),CIN1、CIN2、CIN3及宫颈癌患者HR-HPV DNA阳性率高于慢性宫颈炎患者(P均<0.05).结论 对于宫颈癌及癌前病变,HPV E6/E7 mRNA的阳性率及其诊断的特异性高于HR-HPV DNA,可作为筛查和随访的指标.
