RAGE与RECK在涎腺多形性腺瘤复发及恶变中的表达及意义
|
Abstract:
摘要 目的:检测RAGE、RECK在涎腺多形性腺瘤 (pleomorphic adenoma,PA)初发、复发和恶变中的表达情况及临床意义。方法:免疫组化法分别检测正常13例,PA初发36例、复发8例,恶变10例涎腺组织RAGE及RECK的表达情况,分析其表达的差异性,并探讨其相关性。结果:RAGE在正常、初发、复发及恶变标本中阳性表达率分别为:15.40％、41.70％、62.50％、90.00％,呈逐渐升高的趋势,并且在阳性率和表达强度比较发现,正常、初发组均明显低于复发及恶变组,差异具有统计学意义(P<0.05)。RECK在正常、初发、复发及恶变标本中阳性表达率分别为:76.90％、55.60％、37.50％、20.00％,呈逐渐降低的趋势,并且在阳性率和表达强度比较发现,正常、初发组均明显高于复发及恶变组,差异具有统计学意义(P<0.05)。RAGE和RECK在各组中的表达呈负相关性(r=-0.512,P＜0.05)。结论:本研究结果可能进一步阐述多形性腺瘤复发及恶变的发病机制,为辅助预测患者预后及为患者的综合治疗提供参考
