Abstract:

?目的:分析肺癌组织中toll样受体9(tlr9)表达与肺癌临床病理特征的关系及其对肺癌术后放疗结果的影响。方法:收集2007年3月至2011年12月经本院手术治疗的肺癌病史资料63例,采用免疫组化sp法检测癌组织中tlr9的表达,分析tlr9表达与肺癌临床病理特征的关系;通过对36例肺癌术后放疗患者进行kaplan-meier单因素生存分析和多因素cox回归分析,探讨tlr9表达在肺癌术后放疗生存中的意义。结果:正常肺泡细胞内未见tlr9蛋白阳性表达,而tlr9蛋白定位于肺癌组织的肿瘤细胞质中,阳性表达率为68.3%(43/63)。且随着肿瘤直径增加,tlr9表达阳性率增加(pppp结论:肺癌组织中tlr9表达阳性率升高,tlr9表达和淋巴结转移是肺癌术后放疗患者生存的独立危险因素,tlr9可能成为预测肺癌术后放疗生存的分子生物学指标。
