摘要 目的探讨周围型肺癌CT征象及病理表现与p53、VEGF异常表达的关系。方法搜集本院经术后病理证实的周围型肺癌65例,患者术前均行胸部螺旋CT扫描,对病灶部位加做高分辨力薄层CT扫描,其中28例行增强扫描,术前均未行放疗和化疗。对65例癌组织病理蜡块分别进行p53、VEGF免疫组织化学检测,并与其CT征象进行统计分析。结果周围型肺癌中p53、VEGF蛋白表达与病理类型无关(P>0.05),与病理分级相关(P<0.05)。周围型肺癌p53、VEGF异常表达与肿瘤大小、CT征象中深分叶征、纵隔淋巴结转移、胸膜凹陷征相关(P<0.05),而与毛刺征、空泡征无相关性(P>0.05)。周围型肺癌p53、VEGF表达与CT强化程度相关(P<0.05)。结论周围型肺癌p53、VEGF异常表达与CT征象相关,表明p53、VEGF是其形成的分子生物学基础。
