摘要 目的检测非小细胞肺癌(NSCLC)患者癌组织中的切除修复交叉互补基因1(ERCC1)、表皮生长因子受体(EGFR)和原癌基因Kirsten-Rous肉瘤病毒(K-ras)表达,探讨其与患者预后的关系。方法应用免疫组化法检测97例NSCLC患者癌组织(观察组)及30例癌旁组织(对照组)的ERCC1、EGFR、K-ras表达,比较三者表达与患者生存时间的关系。结果观察组ERCC1、EGFR、K-ras表达阳性率分别为29.9%、22.7%、32.0%,均高于对照组的0、3.3%、0(P均<0.05);且EGFR与K-ras呈负相关(r=-0.371,P<0.01)。NSCLC化疗组ERCC1阳性者的生存时间有低于阴性者的趋势(P>0.05),而非化疗组ERCC1阳性者的生存时间长于化疗组(P<0.05);EGFR阳性而K-ras阴性表达者的生存时间长于EGFR阴性而K-ras阳性表达者(P<0.05)。结论 ERCC1、EGFR、K-ras表达与NSCLC发生、发展有关,是评估患者疗效和预后的重要指标。
