miRNA-31和STAT-3在舌鳞状细胞癌中的表达及临床意义
|
Abstract:
摘要 目的:探讨miRNA-31和STAT-3在舌鳞状细胞癌中的变化及相关性。方法:收集137例舌鳞状细胞癌患者组织标本,利用荧光原位杂交法检测miRNA-31在组织中的表达情况,利用SP免疫组化法检测STAT-3在组织中表达情况,分析miRNA-31和STAT-3在不同分化程度舌鳞癌组织中表达,利用Kaplan-meier法分析miRNA-31和STAT-3表达与生存期的关系。结果:miRNA-31在低分化、中分化和高分化组织中阳性表达率分别为(80.6±14.3)%、(58.5±15.7)%和(23.7±9.4)%,STAT-3分别为(85.9±12.7)%、(51.7±16.3)%和(17.6±9.1)%,差异均具有统计学意义(P<0.05);Spearman等级相关分析显示,舌鳞癌组织中miRNA-31和STAT-3表达呈正相关(r=0.614,P<0.05);生存分析显示,miRNA-31高表达组患者中位生存期37个月,低表达组患者中位生存期65个月,STAT-3高表达组患者中位生存期38个月,低表达组患者中位生存期66个月,差异均具有统计学意义(P<0.001)。结论:miRNA-31和STAT-3舌鳞癌组织中表达与组织分化程度有关,且miRNA-31和STAT-3呈正相关,高表达可影响患者预后
