摘要 目的探讨蛋白激酶C-α(PKC-α)、细胞周期蛋白D1(CyclinD1)在大肠癌组织中的表达及与预后的关系。方法应用免疫组化SP法对47例大肠癌组织,21例腺瘤组织及15例正常大肠组织中PKC-α,CyclinD1的表达进行检测。随访,记录患者的临床病理参数和生存资料。结果PKC-α在大肠癌组织中阳性表达31/47(66.0%)与正常组织3/15(20.0%)及腺瘤10/21(47.6%)相比差异有显著性(P<0.05),与大肠癌分化程度、Dukes分期、淋巴结转移及CEA水平明显相关(P<0.05)。CyclinD1在大肠癌中阳性表达分别为26/47(55.5%),与正常组织中2/15(13.3%)及腺瘤组织中8/21(38.1%)相比呈递增趋势(P<0.05)。CyclinD1阳性表达与肿瘤分化程度、Dukes分期、淋巴结转移呈正相关(P<0.05),而与CEA水平关系不大(P>0.05);PKC-α,CyclinD1阳性大肠癌患者术后5年生存率分别为48.4%,46.2%,明显低于阴性患者81.3%,76.2%(P<0.05)。结论大肠癌发生过程中PKC-α,CyclinD1表达异常,PKC-α,CyclinD1高表达与患者预后差密切相关,对大肠癌预后评估具有重要意义。
