Abstract:

目的研究血清骨桥蛋白(OPN)在非小细胞肺癌中的表达,探讨OPN与非小细胞肺癌预后相关因素之间的关系。方法收集2007年5月-2009年8月宁夏医科大学总医院呼吸内科、心胸外科非小细胞肺癌患者126例,12例患者病例资料不完整失访,随访截至2010年8月31日,共随访完整资料患者114例,采用ELISA法测定非小细胞肺癌患者血清OPN。采用卡方检验、Kaplan-Meier法分析血清OPN与非小细胞肺癌患者生存时间的关系,绘制生存曲线,并用Cox比例风险模型进行影响因素分析。结果114例患者中血清OPN水平高于中位数组的共60例,平均生存时间(14.33±9.79)个月,血清OPN水平低于中位数组的共54例,平均生存时间(12.71±7.89)个月,差异无统计学意义(P>0.05)。血清OPN水平高于中位数组与低于中位数组患者的1、2、3年的生存率比较差异无统计学意义(P>0.05),而血清OPN水平的高低与临床分期、淋巴结转移及远处转移比较差异有统计学意义(P均0.05);临床分期是影响生存时间的危险因素(P0.05)。结论非小细胞肺癌患者血清OPN水平的高低与其临床分期、淋巴结转移、远处转移呈正相关,但单一指标不能作为判断非小细胞肺癌患者临床预后转归的依据。
