摘要 目的探讨Cyclin D1、p21WAF1在结直肠癌(CRC)组织中的表达及其临床意义。方法选择40例CRC患者的肿瘤切除标本(CRC组)及癌旁组织(癌旁组)、12例CRC癌前病变(癌前组)、10例正常结直肠黏膜组织(正常组),应用流式细胞术检测各组Cyclin D1、p21WAF1表达。结果与癌旁组、癌前组及正常组比较,CRC组Cyclin D1表达率升高,p21WAF1表达率降低(P均<0.01);正常组Cyclin D1表达率明显低于癌前组、癌旁组(P均<0.05)。相关回归分析显示,Cyclin D1和p21WAF1表达率呈负相关(r=-0.257,P<0.01)。CRC组Cyclin D1、p21WAF1表达率与Dukes分期及肿瘤分化程度有关(P<0.01)。结论 Cyclin D1、p21WAF1在CRC演变过程中起重要作用,可作为CRC早期诊断和预后评定的重要指标。
