2、间比较采用Mann-WhitneyU检验;计数资料两组间比较采用必检验;相关分析采用SPearman相关性检验;DeLong检验匕饰亦同受试者工作特征曲线(ROC曲线)下面积(AUC)的差异结果与胆总管结石组比较,胆管癌患者胆汁中钙卫蛋白水平升高4795.50(2286.7920179.73)ng/mLvs411.16(67.031991.88)ncmL,3=5.572,P0.05胆汁钙卫蛋白水平与胆汁白细胞计数、血红蛋白、乳铁蛋白水平具有相关性(值分别为0.316、0.353、0.464,产值均0.05)。RoC曲线结果示胆H钙卫蛋白(敏感度79.4%,特异度75.6%)、血CA19-9水平
3、(敏感度82.4%,特异度78.2%)以及两者联合(敏感度88.2%,特异度73.1%)对诊断胆管癌具有良好的敏感性和特异性.结论胆管癌患者胆汁中钙卫蛋白水平升高,可能成为胆管癌诊断的生物标志物。关键词:胆管肿瘤;胆总管结石病;白细胞L1抗原复合物基金项目:安徽省自然科学基金青年项目(2008085QH415)ClinicalsignificanceofdeterminingthelevelofbiliaryCalprotectininpatientswithCholangiocarcinomaorCholedocholithiasisJlTingting,BAIBingqing,CUIYuf
