摘要 目的探讨乳腺浸润性导管癌动态增强磁共振成像(DCE-MRI)的影像特征及其与癌组织nm23、P53表达的关系。方法对58例乳腺癌患者于手术治疗前行DCE-MRI检查,分析病灶形态、边缘、内部增强情况,绘制时间—信号强度曲线。术中留取肿瘤组织,采用免疫组化法检测nm23、P53;对乳腺癌DCE-MRI影像特征(病灶形态、边缘类型、内部强化特征、时间—信号强度曲线类型)与癌组织中nm23、P53表达的关系进行分析。结果DCE-MRI共发现病灶65个。病灶形态(圆形或椭圆形、分叶状、不规则形)、病灶边缘(光滑、不规则、毛刺状)、内部强化特征(均匀、不均匀、环形强化)与nm-23、P53表达无显著关联性(P均>0.05);时间—信号强度曲线类型与nm-23表达有关(r=0.31P均<0.05)。结论乳腺浸润性导管癌DCE-MRI的时间—信号强度曲线类型与癌组织中nm23的表达有关,Ⅲ型曲线者肿瘤侵袭性可能更强。
