摘要 目的检测胃肠道肿瘤患者外周血Survivin及其剪接变体△EX3 mRNA的表达水平,探讨其在胃肠道肿瘤的发生、发展及预后判断中的临床应用价值。方法采用RT-PCR方法检测40例胃肠道肿瘤患者和20例健康体检人员外周血Survivin及其剪接变体△EX3 mRNA的表达情况。结果 40例肿瘤患者检测到35例Sur-vivin mRNA表达、29例Survivin-△EX3 mRNA表达,20例健康体检人员检出1例Survivin mRNA表达,未检出Survivin-△EX3 mRNA表达,两者差异有统计学意义;Survivin mRNA在胃肠道肿瘤患者外周血表达的阳性率与临床病理特征无相关性,但其相对表达水平与淋巴结转移及临床病理分期密切相关。Survivin-△EX3 mRNA在胃肠道肿瘤患者外周血表达的阳性率和相对表达水平与分化程度、淋巴结转移及临床病理分期均密切相关。结论外周血中Survivin mRNA、Survivin-△EX3 mRNA的阳性表达与胃肠道肿瘤关系密切;胃肠道肿瘤患者外周血Survivin mRNA、Survivin-△EX3 mRNA的表达及肿瘤分化程度、淋巴结转移和临床病理分期有一定关系。
