摘要 目的:比较乳腺癌新辅助化疗前后Ki-67的变化情况,探讨Ki-67的改变与临床疗效之间的关系。方法:II﹣III期浸润性乳腺癌女性患者70例,术前接受新辅助化疗;应用免疫组织化学法(IHC)检测在化疗前巴德针穿刺的活检组织和乳腺癌改良根治术后或保乳术后标本中的Ki67表达情况,比较新辅助化疗前后Ki-67的变化情况与临床疗效的关系。结果:70例乳腺癌新辅助化疗前后对比结果显示,新辅助化疗前后Ki-67表达变化有统计学意义(P<0.05),Ki-67的变化率为82.85%;应用WHO标准评价,Ki-67下降组中临床缓解率分别为PCR(完全病理缓解)7例(10%),CR(完全临床缓解)6例(8.57%),PR(部分缓解)25例(35.71%),SD(疾病稳定)10例(14.28%),PD(疾病进展)1例(1.43%),Ki-67表达变化与临床缓解率间相互关联,具有统计学意义(P<0.05),提示Ki-67的表达下降越明显,临床缓解率相对较高。结论:乳腺癌的新辅助治疗中,Ki-67可作为预测新辅助化疗临床疗效的一个敏感指标,对临床用药和化疗结局有一定的指示作用。
