摘要 目的探讨自噬基因Beclin-1、凋亡基因Bax、Bcl-2在食管鳞癌中的表达及意义。方法采用免疫组化SP法检测45例食管鳞癌组织中Beclin-1、Bax和Bcl-2的表达水平,并分析其与临床病理因素的关系。结果食管鳞癌中Beclin-1表达水平低于正常食管组织(P<0.05);Beclin-1表达随食管鳞癌的组织分化程度、T分期、N分期的升高而下调(P均<0.05)。在正常食管组织中Bax微弱表达,Bcl-2未见表达,两者在食管鳞癌中的表达均显著上调。Bax蛋白表达随食管鳞癌组织分化程度的增加而增加,Bcl-2的表达则相反(P均<0.05)。结论自噬基因Beclin-1、凋亡基因Bax及Bcl-2在食管鳞癌的发生、发展中起协调作用,对其联合检测有助于食管鳞癌的早期诊断和预后判断。
