摘    要:目的探讨Tenascin、CD34在胆管癌的发生、发展中的作用和意义。方法收集我院1995年-2003年期间切除的胆管癌标本33例和正常胆管组织4例,采用免疫组织化学S-P方法,检测其Tenascin、CD34的表达情况。结果Tenascin在胆管癌组织中的阳性表达率为81.8%(27/33),其中病理分级Ⅰ级、Ⅱ级、Ⅲ级的阳性率分别为71.4%、82.4%和88.9%,但无显著性统计学差异(P>0.05);在正常胆管组织中未检测到Tenascin表达。CD34在胆管癌组织中广泛表达,在正常胆管组织中仅有少量表达,两者相比具有显著统计学差异(P<0.05)。结论Tena-scin可以作为胆管癌的肿瘤标志应用于临床诊断,CD34可作为预测肿瘤转移的一项重要指标。

关 键 词:胆管癌  Tenascin  CD34  免疫组织化学

Abstract:Objecive To investigate the role of tenascin and CD34 in occurence and development of cholangiocarcinoma.Methods The expression of tenascin and CD34 were examined in 33 patients,16 males,17 femalse,ranged 32-70 years with cholangiocancinoma and in 4 cases of normal bile duct tissue by S-P immunohisto chemical technique.Results TN expression was located in the stroma of cholangiocarcinoma.The proportion of positive TN expression was 81.8%(27/33).The positive rate of pathologic grade Ⅰ,Ⅱ and Ⅲ were 71.4%,(82.4%) and 88.9%,respectively.There was no significant difference among the three graded groups.TN expression wasn't detected in normal tissues(P>0.05).CD34 showed widespread expression in cholangio-carcinoma tissues,but limited in normal bile duct,which showed significant difference(P<0.05).Conclusion TN was over expressed in cholangiocarcinoma compared with negative expression in normal tissues,which suggested the diagnostic value of TN for cholangiocarcinoma.The levels of MVD marked by CD34 were significantly higher in cholangiocarcinoma than that in normal tissue.What's more,there were significant correlation between MVD and pathologic grades and/or metastasis.
Keywords:cholangiocarcinoma  tenascin  CD34  immunohistochemistry
