简介：客观：在乳癌学习P-glycoprotein(P-gp)的临床的意义。方法：在乳癌的60种情况中的P-gp的表示被immunohistochemistry检验。到化疗的P-gp表示和反应比较地与变形乳癌在19个病人被调查。结果：P-gp在乳癌的60个案例中的48.3%个中是积极的。P-gp表示不与病人的年龄，月经地位，包含的腋的淋巴节点的数字，临床的阶段，组织学的类型，和神经质的受体地位有关(P>0.05)。转移(62.1%)和死亡(51.7%)的频率比在否定情况中在P-gp积极案例中是更高的(16.1%对12.9%，P<0.005)。P-gp积极案例(48.3%)的5年的幸存率比否定案例(87.1%)的显著地低(P<0.05)。在收到了辅助化疗的病人，远转移比在P-gp否定案例(57.1%)(P=0.0468)中更经常发生在P-gp积极案例(94.7%)中。更多的P-gp否定病人(7/9)对化疗(P=0.0055)比积极病人(1/10)应答。结论：P-gp表示的Immunohistochemical检查在在乳癌病人预言反应到化疗和预后是有用的。P-gp确实与差的预后被联系。
