摘要 目的探讨宫颈浸润性鳞状细胞癌(ISCC)、宫颈上皮内瘤变(CIN)中HPV 16/18感染与ki-67、P16INK4a蛋白的表达及其在宫颈鳞癌发生、发展中的作用与相关性,以利于宫颈癌的防治和早期诊断。方法采用免疫组织化学方法对116例宫颈组织标本进行ki-67、P16INK4a的检测,同时应用原位杂交技术检测HPV16/18。结果(1)HPV原位杂交结果:ISCC组、CIN组、宫颈尖锐湿疣组、分别与正常宫颈组相比,HPV阳性表达有显著性差异,且阳性率从CINⅠ到CINⅢ到ISCC呈上升趋势;(2)免疫组化结果:与正常宫颈组相比,Ki-67、P16INK4a的阳性表达在ISCC组、CIN组均有显著性差异;(3)在宫颈浸润性鳞癌组织中表达的相互关系:ki-67、P16INK4a与HPV16/18间的表达具有相关性。结论ki-67、P16INK4a在宫颈鳞癌中的高度表达与HPV16/18感染有关,它们均可能作为有价值的诊断指标应用于宫颈癌高危人群筛查。
