摘要 目的:研究周期蛋白B1(cyclin B1)在Barrett食道、Barrett食道合并不典型增生和食道腺癌中的表达,评定在Barrett食管中周期蛋白B1作为肿瘤进展标记物的临床价值,同时通过检测在Barrett食道粘膜肠上皮化生-不典型增生-腺癌序列不同阶段该指标的表达探讨其与肿瘤发生发展的关系。方法:应用免疫组化法测定周期蛋白B1,实验样本取自Barrett食管25例,其中18例合并单纯肠化(SE),7例合并不典型增生(DY),食管腺癌(CA)12例,10例正常食道粘膜组织作为对照。结果:周期蛋白B1在研究组检测样本中均有高的表达率,而对照正常食管粘膜组织均无表达,相比差异有显著性,且在SE组、DY组、CA组的组织中周期蛋白阳性细胞逐渐增多,差异显著。结论:Cy-clinBl可能作为一肿瘤进展标记物来评估患者进展为腺癌的危险性,并可能在食管腺癌进程中起一定作用。
