摘要 目的探讨外周血miRNA-1246对前列腺癌患者临床、病理特征的影响及对预后判断的价值。方法选取88例行手术治疗的前列腺癌患者作为前列腺癌组,同时选取62例单纯性前列腺增生患者及60例健康志愿者分别作为增生组和健康对照组,采用反转录实时荧光定量PCR检测外周血miR-1246的表达水平,并进行随访。统计分析miR-1246表达水平与患者临床、病理特征和生存期的影响。结果与增生组、健康对照组比较,前列腺癌组的外周血miR-1246表达水平较高,差异有统计学意义(P<0.05)。miR-1246表达水平对患者Gleason评分、T分期、N分期、M分期、危险因素分级有明显的不良影响(P<0.05)。miR-1246低表达水平与高表达水平患者的总体生存率比较,差异无统计学意义(P=0.232),但低表达组患者的无生化复发生存期显著高于高表达组(P<0.05),Cox多因素分析显示,miR-1246表达水平也是影响患者无生化复发生存期的独立性危险因素(P<0.05)。结论miR-1246的高表达对前列腺癌患者的临床病例特征有一定的不良影响,且与患者的生化复发密切相关。
