目的:探讨乳腺癌组织中乳腺癌耐药蛋白(breast cancer resistance protein,BCRP)和Ki-67的表达与新辅助化疗疗效之间的关系。方法:回顾性分析我科2012年10月至2014年8月收治的Ⅱ-Ⅲ期乳腺癌新辅助化疗患者65例,采用免疫组化方法检测BCRP和Ki-67的表达,分析BCRP、Ki-67的表达水平与新辅助化疗疗效的关系。结果:原发性乳腺癌组织中BCRP的阳性表达率为67.7%。BCRP的表达水平与新辅助化疗后病理组织学反应有关,组织学显著反应组(病理反应4~5级)BCRP的表达水平明显低于非显著反应组(病理反应1~3级),差异有统计学意义(χ~2=12.77,P=0.001)。化疗前Ki-67高表达组临床缓解率明显高于低表达组(χ~2=17.72,P<0.00)。结论:联合检测乳腺癌组织中BCRP和Ki-67的表达水平对新辅助化疗疗效有一定的预测价值。
【英文摘要】
Objective: To investigate whether the expression of BCRP and Ki-67 expression in breast cancer could predict the efficacy of neoadjuvant chemotherapy. Methods: This research retrospectively analyzed 65 patients,who were diagnosed as invasive ductal carcinomas in stage Ⅱ-Ⅲ admitted in the breast cancer center in our hospital and accepted NAC from October 2012 to Augest 2014. Immunohistochemical assay was used to detect the BCRP and Ki-67 protein levels of 65 breast cancer tissues obtained by core needle biop...
