摘要 目的探讨抗VEGF抗体Bevacizumab对人胆管癌移植瘤裸鼠模型的抗血管生成作用。方法建立人胆管癌裸鼠移植瘤模型55只。将55只荷瘤鼠随机分为对照组15只、药物1组及药物2组各20只。药物1组及药物2组分别予Bevacizumab 5、10 mg/kg腹腔注射,对照组腹腔注射等量生理盐水,均每周2次,连续给药4周。治疗结束后处死小鼠,测量肿瘤体积,免疫组化SP法检测瘤组织中VEGF表达水平,CD34标记微血管染色,计算微血管密度(MVD)。结果药物1组及药物2组肿瘤体积明显小于对照组(P<0.05),但两组比较无统计学差异;药物1组及药物2组VEGF阳性细胞百分比均低于对照组,但无统计学差异;药物1组及药物2组MVD均显著低于对照组(P<0.05),但两组间无统计学差异。结论 Bevacizumab可抑制胆管癌血管生成,其机制可能为抑制VEGF表达。
