摘要 目的探讨在评价肿瘤新生血管和手术患者预后方面,CD105的作用及其是否优于CD34。方法选取原发性肝癌根治切除术的石蜡包埋标本100例,每例标本取两个肿瘤组织点位和一个癌旁非肿瘤组织点位,构建孔径为1.1 mm,15×10排列的组织芯片块两块,连续切片后分别用CD105、CD34、VEGF单克隆抗体进行免疫组化染色,进行CD105标记的微血管密度(MVD-CD105)和CD34标记的微血管密度(MVD-CD34)定量计数、VEGF的半定量计数,并与相应患者的临床病理学参数和无病生存期进行统计学分析。结果肿瘤内MVD-CD105数值随VEGF表达的增强而升高,有直线相关关系(r=0.227,P<0.05),但MVD-CD34与VEGF表达强度无相关(r=0.172,P>0.05)。肿瘤内MVD-CD105与有无静脉侵犯有关(P<0.05),但MVD-CD34与之无关(P>0.05)。将肿瘤组织内MVD值的均数做为分界,高MVD-CD105组较低MVD-CD105组的无病生存期降低有统计学意义(P<0.01),而高MVD-CD34组和低MVD-CD34组相比,无病生存期则差异无显著性(P>0.05)。另外癌旁非肿瘤组织CD105阳性组的无病生存期也较阴性组明显降低(P<0.05)。结论CD105在标记肝癌新生血管方面优于CD34,肿瘤内MVD-CD105在判断原发性肝癌术后患者预后方面也优于MVD-CD34,癌旁非肿瘤组织内CD105的阳性表达与患者肿瘤早期复发,转移有关。
