摘要 [目的]探讨食管癌中p16与survivin蛋白的表达及其与临床病理特征的关系。[方法]采用EnVision免疫组化法检测62例食管癌及其相应癌旁正常黏膜组织的p16与survivin蛋白的表达。[结果]癌旁正常黏膜中的p16与survivin蛋白的阳性表达率分别为91.9%和6.45%,而相应癌组织分别为32.3%和72.6%。两组间均有显著性差异(P<0.01)。食管癌中p16表达的缺失与组织学分级、临床分期和淋巴转移有关(P<0.05)。而survivin蛋白阳性表达则与淋巴转移有关(P<0.05),而与组织学分级、临床分期无关(P>0.05)。p16与survivin蛋白在食管癌中的表达呈负相关(r=-0.495,P<0.01)。[结论]p16表达的缺失与survivin蛋白的过度表达与食管癌的发生、进展和淋巴结转移密切相关,两者联合检测有助于食管癌病情的评估和预后判断。
