摘要 目的研究细胞周期素E(Cyclin E)、p27kipl和Ki67在大肠癌的表达及临床病理意义。方法应用免疫组化Power Vision两步法检测137例大肠癌及其邻近正常黏膜组织中Cyclin E、p27kipl和Ki67的表达,并分析它们与大肠癌临床病理特征的关系。结果大肠癌组织中Cyclin E及Ki67表达水平显著高于邻近正常黏膜组织,并与原发肿瘤浸润深度、区域淋巴结转移及TNM分期显著正相关。大肠癌组织中p27kipl表达水平显著低于邻近正常黏膜组织,并与原发肿瘤浸润深度、区域淋巴结转移及TNM分期显著负相关。大肠癌组织中Cyclin E与p27kipl表达水平显著负相关;Cyclin E和Ki67表达水平显著正相关;大肠癌组织中p27kipl与Ki67表达水平呈显著负相关。结论Cyclin E和p27kipl是大肠癌的发生及侵袭转移的正性因子和负性因子,联合检测Cyclin E、p27kip1和Ki67有助于判断大肠癌的恶性程度及生物学行为,并判断预后,为大肠癌的个体化治疗提供依据。
