1、摘要目的:本课题拟研究Ku70、Ku80和DNA.Pkcs在食管腺癌及其癌前病变,食管鳞癌及其癌前病变中的表达情况,并探讨Ku70、Ku80和DNA.Pkcs可能对食管肿瘤发生、发展所起的作用。方法:收集石河子大学医学院第一附属医院2001.2008年123例胃镜活检食管腺癌、Barrett食管、正常食管胃交界处贲门黏膜石蜡标本;21l例胃镜活检食管鳞癌、鳞状上皮内瘤变、正常鳞状上皮组织石蜡标本。首先进行光镜观察,再免疫组织化学法检测Ku70、Ku80和DNA.Pkcs在上述组织中的表达情况。最后使用SPSSl3.0对实验结果进行f检验。结果:K
2、u70、Ku80和DNA.Pkcs在食管腺癌、Barrett食管、正常食管胃交界处贲门黏膜中均有表达,三组表达的两两相比较具有统计学意义(P<0.0125)。Ku70、Ku80和DNA.Pkcs在食管鳞癌、鳞状上皮内瘤变、鳞状上皮单纯增生中均有表达,Ku70、Ku80在食管鳞癌、鳞状上皮内瘤变、鳞状上皮单纯增生中的表达各间均有差异,有统计学意义(P<0.0125)。DNA—Pkcs在食管鳞癌、鳞状上皮内瘤变两组间差异表达无意义(P>0.0125),而在鳞状上皮内瘤变、鳞状上皮单纯增生两组间差异表达有意义(氏O.0125),在食管鳞癌、鳞状上皮单纯
