摘要 目的探讨干细胞特异性基因OCT-4在各亚型乳腺浸润性导管癌发生、发展中的作用。方法采用免疫组化法检测120例四种不同亚型乳腺浸润性导管癌组织中的OCT-4表达情况,并分析其与患者淋巴结转移及雌激素受体(ER)、孕激素受体(PR)、原癌基因人类表皮生长因子受体-2(HER-2)表达的关系。结果 OCT-4主要表达于细胞核,总阳性率为19.17%(23/120),其中Luminal A型、Luminal B型、Basal-like型、HER-2过表达型OCT-4表达阳性率分别为17.39%(8/44)、19.23%(5/26)、18.75%(6/32)、25.00%(4/16),两两比较P均>0.05(χ2=0.61);Luminal B型、HER-2过表达型中有局部淋巴结转移者OCT-4表达阳性率显著低于无局部淋巴结转移者(P<0.05);OCT-4表达与ER、PR、HER-2的表达均无明显相关性(P>0.05)。结论 OCT-4表达可能影响乳腺浸润性导管癌的浸润、转移及预后,但在各亚型间的作用无显著差异。
