摘要
目的:探讨新辅助化疗前后Survivin、MRP1在宫颈鳞癌组织中的表达及其与化疗敏感性的关系。方法:采用免疫组化SP法对38例宫颈鳞癌患者新辅助化疗(NACT)前后MRP1、Survivin的表达水平进行检测。结果:NACT前Survivin的阳性表达率(63.16%)显著高于NACT后(39.47%)(P<0.05),且NACT前Survivin表达阴性者化疗有效率(92.86%)高于表达阳性者(62.50%)(P<0.05)。Survivin的表达水平与宫颈鳞癌的分化程度相关(P<0.05),但与年龄、临床分期不相关(P>0.05)。新辅助化疗前后MRP1在宫颈鳞癌中的阳性表达率分别为84.21%和92.11%,两者间无显著性差异(P>0.05),且化疗前MRP1表达阴性者与表达阳性者化疗有效率分别为83.33%、71.88%,两者间无显著性差异(P>0.05)。MRP1的表达与宫颈癌的临床分期、分化程度、年龄均不相关(P>0.05)。结论:Survivin、MRP1在宫颈鳞癌组织中均有较高的表达水平,但只有Survivin的表达水平与NACT疗效具有显著的相关性,Survivin的表达水平可作为预测宫颈鳞癌对化疗敏感性的指标。
Objective: To investigate the expression of Survivin and multiple resistance - associated protein - 1 ( MRP1 ) in cervical squamous cancer before and after neoadjuvant chemotherapy(NACT) and its relation with tumor chemosensitivity and related clinical pathological factors. Methods:The specimens of 38 patients with cervical squa- mous cancer before and after NACT were examined by SP immunohistoehemistry. The correlation between Survivin and MRP1 expression and therapeutic effect was analyzed. Results:Survivin positive expression rate in cervical squamous cancer before NACT was 63.16% , which was significantly higher than that after NACT (39.47%) (P 〈 0.05 ). The effective rate of patient with Survivin negative expression before NACT was 92.86% , which was significantly higher than of patient with Survivin positive expression( 62.50% ) ( P 〈 0.05 ). Survivin expression levels were negatively re- lated to the differentiation of the tumor( P 〈 0.05 ), but not related to age and clinical stages( P 〉 0.05 ). MRP1 posi- tive expression rates in cervical cancer before and after NACT were 84.21% and 92.11% respectively and the differ- ence was not significant( P 〉 0.05 ). The effective rates of patient with MRP1 negative expression in cervical squa- mous cancer before chemotherapy were 83.33% and 71.88% respectively and the difference was not significant( P 〉 0.05 ). MRP1 expression levels were not related to clinical stages, differentiation of the tumor or age ( P 〉 0.05 ). Conclusion:The expression levels of Survivin, MRP1 were higherin cervical squamous cell carcinoma,but only Sur- vivin expression levels are significantly associated with response to chemotherapy and it can be used as a predictive marker of the sensitivity to NACT in patients with cervical squamous cancer.
