摘要(Abstract):
目的:探讨谷胺甘肽S-转移酶、脱氧核糖核酸拓扑Ⅱ的表达与晚期宫颈癌化疗的关系。方法:应用免疫组化S-P法检测28份晚期宫颈癌组织化疗前后GST-π和DNATopoⅡ的表达。结果:化疗前28份宫颈癌组织中GST-π过表达17份(60.71%),DNA TopoⅡ低表达16份(57.14%);化疗后GST-π过表达24份(85.71%),DNA TopoⅡ低表达18例(64.28%)。化疗前后GST-π的表达差异有显著性(P<0.05),DNA TopoⅡ的表达差异无显著性(P>0.05),二者表达有相关性(P=0.019)。GST-π过表达和DNATopoⅡ低表达与患者的化疗反应呈负相关(P=0.014,P=0.038)。结论:GST-π过表达与宫颈癌内在性耐药和获得性耐药有关,DNA TopoⅡ低表达只与宫颈癌内在性耐药有关。GST-π和DNA TopoⅡ的表达均能很好地预测晚期宫颈癌患者的化疗耐药与反应。
