摘要 目的探讨细胞周期素-E(Cyclin-E)在宫颈鳞癌、宫颈上皮瘤变(cervical intraepithelial neoplasia,CIN)中的表达及意义。方法应用免疫组化S-P法检测20例宫颈鳞癌、58例CIN及10例正常宫颈组织中Cyc-lin-E的表达,采用图像分析技术并以阳性单位(positive unit,PU)定量表达免疫组化阳性反应结果。结果 Cyc-lin-E在CIN及宫颈鳞癌中表达的PU值分别为18.67±2.25及25.80±2.62,而正常宫颈组织中无表达,3组比较差异有统计学意义(P<0.001)。在CINⅠ、CINⅡ及CINⅢ中Cyclin-E表达的PU值分别为8.17±2.35、18.48±1.75及29.20±3.74,3组间比较差异有统计学意义(P<0.01);在高分化、中分化及低分化宫颈鳞癌中Cyclin-E表达的PU值分别为22.15±1.06、25.06±1.28及30.41±1.13,3组间比较差异有统计学意义(P<0.01)。结论宫颈鳞癌及CIN的发生与Cyclin-E的过度表达相关,Cyclin-E的过度表达与宫颈鳞癌细胞分化程度相关。
