摘要 目的观察乳腺癌组织中Delta样配体4(DLL4)、血管内皮生长因子(VEGF)的表达变化,并探讨其临床意义。方法采用免疫组化法检测122例浸润性导管癌组织(导管癌组,其中Ⅰ级33例,Ⅱ级40例,Ⅲ级49例)和28例导管原位癌组织(原位癌组)中的DLL4、VEGF,分析两指标间及与乳腺癌临床病理参数的相关性。结果导管癌组Ⅰ级、Ⅱ级、Ⅲ级及原位癌组DLL4阳性率分别为48.5%、75.0%、91.8%、21.4%,VEGF阳性率分别为42.4%、72.5%、91.8%、17.9%,两组比较,P均<0.05;DLL4、VEGF的表达与乳腺癌肿瘤直径、TNM分期、淋巴结转移有关(P均<0.05);乳腺癌组织中DLL4和VEGF表达呈正相关(r=0.208,P=0.011)。结论 DLL4在乳腺癌组织中的表达上调与VEGF有关,两者可能共同调控肿瘤血管生成并与乳腺癌的发展及预后相关,可作为预测乳腺癌预后的重要参考指标。
