摘要 目的研究胰岛素样生长因子结合蛋白2(IGFBP-2)在原发性肝细胞癌(HCC)中的表达及其与临床病理特征的关系。方法选取67例HCC手术切除的新鲜标本和16例正常肝组织。应用EnVision^TM二步染色免疫组化法,利用兔抗人IGFBP-2多克隆抗体对组织切片进行染色,并对IGFBP-2在HCC中的表达及其临床病理特征的关系进行研究。结果IGFBP-2在HCC组织中的阳性率为56.72%,明显高于正常肝组织的12.5%(P〈0.01),IGFBP-2在低分化的HCC组织中的表达明显高于中分化与高分化HCC组织(P〈0.01)。IGFBP-2在肿块体积≥5cm的HCC组织中表达明显高于肿块体积〈5cm的HCC组织(P〈0.01)。结论IGFBP-2促进HCC的发生发展,可能与IGFBP-2在HCC生长过程中有较强的致有丝分裂原活性,抑制HCC细胞分化与凋亡有关。
