摘要 目的探讨细胞周期调节基因(RGCC基因)在胃癌发生、发展中的作用。方法选择胃癌患者65例,取其保存完整的胃癌组织及配对癌旁组织标本,采用实时定量PCR法检测RGCC mRNA相对表达量。采用单因素方差分析RGCC表达与胃癌患者临床病理参数的关系,以胃癌组织中RGCC mRNA相对表达量的平均值为界,将患者分为高表达组和低表达组,比较两组5年生存率。结果胃癌组织RGCC mRNA相对表达量为2.505±0.502,癌旁组织为1.068±0.107,RGCC基因在胃癌组织中的表达明显高于癌旁组织(P<0.01)。BorrmannⅢ/Ⅳ型、弥漫型生长、分化程度低、浸润程度深、存在脉管癌栓、淋巴结分期晚的患者胃癌组织RGCC mRNA表达明显升高(P<0.05或<0.01),不同性别、年龄、癌灶大小及部位者胃癌组织RGCC mRNA表达均无统计学差异(P均>0.05)。高表达组5年生存率为31.0%,低表达组为64.2%,两组比较有统计学差异(P<0.01)。结论 RGCC基因在胃癌组织中表达升高,与肿瘤的恶性生物学行为和患者预后不良有关。
