Abstract： 目的探讨术前区域动脉灌注化疗对血管内皮生长因子(VEGF)蛋白表达及肿瘤血管生成的影响.方法通过免疫组织化学方法,检测术前区域动脉灌注化疗及根治手术的结直肠癌病例癌组织中微血管密度(MVD)和VEGF蛋白表达水平,并与同期未行术前动脉化疗而直接手术的31例病例作比较.结果术前动脉化疗组的MVD值为19 2±5 2,而对照组为42.4±1 8.4,两组间差异有显著性意义(P＜001).术前动脉化疗组VEGF表达亦明显低于非化疗组(P＜0.01).术前化疗组肿瘤的MVD与VEGF表达相关分析表明两者间存在正相关(r=0.788,P＜005),VEGF的表达与肿瘤Dukes分期相关且有统计学意义.结论结直肠癌术前区域动脉化疗可以通过抑制肿瘤细胞分泌VEGF蛋白,或直接作用于肿瘤血管,减少肿瘤的血管生成,减少肿瘤细胞的血供.从而改善结直肠癌患者的治疗效果和预后
