摘要 目的:探讨可溶性E-钙黏蛋白(soluble E-cadherin,sE-cadherin)在乳腺癌新辅助化疗效果及预后评估中的价值。方法:采用酶联免疫吸附试验检测80例乳腺癌患者(观察组)及30名健康体检者(对照组)的血清sE-cadherin水平。对临床分期为Ⅱ~Ⅲ期的乳腺癌61例患者进行化疗,按实体瘤疗效评价标准分为有效组(36例)和无效组(25例)。采用Kaplan-Meier法分析sE-cadherin水平与患者5年生存率的关系。结果:观察组血清sE-cadherin水平显著高于对照组(P<0.05)。血清sE-cadherin诊断乳腺癌的受试者工作特征曲线(receiver operating characteristic curve,ROC曲线)下面积(area under the curve,AUC)为0.762,糖类抗原153的AUC为0.654;血清sE-cadherin水平与乳腺癌临床分期、肿瘤大小、有无淋巴结转移和病理分级有关;乳腺癌61例患者化疗后血清sE-cadherin水平显著低于化疗前(P<0.05)。有效组化疗后血清sE-cadherin水平明显低于化疗前(P<0.05),而无效组化疗前、后血清sE-cadherin水平差异无统计学意义(P>0.05)。在化疗2个周期后,sE-cadherin低水平组有效率显著高于高水平组(P<0.05)。Kaplan-Meier生存分析显示,sE-cadherin低水平组5年生存率显著高于高水平组(P<0.05)。结论:血清sE-cadherin在乳腺癌新辅助化疗效果及预后评估方面有一定的临床意义。
