1、大连医科大学硕士学位论文阴性,NAC前后表达变化没有统计学意义(P>O.05)。NAC前PR(+)为17例,NAC后PR(+)为19例;NAC前PR㈠为23例,NAC后PR(--)为21例,PR改变6例(15.0%),其中4例阴性转变为阳性,2例阳性转变为阴性,差异没有统计学意义(P>0.05)。NAC前h.67(+)为22例,NAC后l(i.67(+)为12例,NAC前ki.67(--)为18例,NAC后ki.67(--)为28例;ki.67改变18例(45.0%),其中4例阴性转变为阳性,14例阳性转变为阴性,差异有统计学意义(P<0.05)
2、。NAC前HER.2过度表达者为23例,、NAC后HER-2过度表达者25例,NAC前非过度表达者为17例,NAC后非过度表达者为15例,HER.2改变10例(25.O%),其中6例阴性转变为阳性,其中4例阳性转变为阴性,比较表达变化无统计学意义(P>0.05)。NAC可部分改变l(i.67的表达,而ER、PR、HER.2的表达不受NAC的影响。结论:FEC.T方案对于乳腺癌患者疗效肯定。NAC前ER、Ki.67表达可以预测NAC的疗效。NAC后飚.67表达降低,NAC可以改变Ki.67的表达水平,为肿瘤个体化治疗提供参考。关键词:新辅助化疗雌激
