| 摘 要： | 目的 研究SEL1L和p63蛋白在食管鳞状细胞癌和癌前病变中的表达.方法 应用免疫组化EnVision二步法分别检测食管鳞状细胞癌(鳞癌组,n=60)、上皮内瘤变(高级别组n=32,低级别组n=13)和正常食管黏膜(对照组,n=33)SEL1L和p63蛋白的表达.结果 鳞癌组及上皮内瘤变高级别和低级别组SEL1L蛋白的阳性表达率分别为96.7%、90.6%、61.5%,p63蛋白的阳性表达率分别为100.0%、100.0%、92.3%,与对照组SEL1L和p63蛋白的阳性表达率(6.1%和51.5%)比较差异均有统计学意义(P<0.01);Pearson相关分析显示,SEL1L和p63的表达与患者性别、年龄及肿瘤位置、大小、分化程度、浸润深度、淋巴结转移、临床分期均无明显相关性(P>0.05),但二者在高级别上皮内瘤变中的表达呈显著正相关(r=0.361,P<0.05).结论 SEL1L和p63在食管鳞癌演进过程中呈递增性过表达.提示二者可能参与食管鳞癌的发生机制并具有一定的协同作用.
