摘要 目的:通过检测晚期肺鳞癌组织中修复基因家族中ERCC1、RRM1和BRCA1的表达,探讨三者表达水平与GP两药联合方案化疗疗效的相关性及其临床意义。方法:应用免疫组化法检测入组病人肺鳞癌组织中ERCC1、RRM1及BRCA1蛋白表达。对明确诊断为ⅢB/Ⅳ期肺鳞癌且体能状态、体力状况ECOG评分、预生存期≥3个月的病人可入选本组研究。均进行GP方案化疗,再休息3周为1个周期,每2个周期行胸、腹部CT主体病灶做1次疗效评价,疗效评价按照实体瘤疗效评价标准1.1版(RECIST1.1),共4个周期。分析病人的性别、年龄、吸烟、化疗反应及预后与肿瘤组织中ERCC1、RRM1和BRCA1蛋白表达的关系。结果:ERCC1、RRM1、BRCA1不同表达水平与病人临床特征比较差异无统计学意义;纳入研究病人化疗总有效率38.6%,ERCC1、RRM1、BRCA1的表达三者均阴性晚期肺鳞癌病人,给以GP方案化疗有效率显著高于三者均阳性表达者。结论:修复基因ERCC1、RRM1、BRCA1可作为晚期肺鳞癌使用GP方案疗效的预测基因;组织中三者均阴性表达的肺鳞癌病人可能是选用GP化疗方案治疗的获益群体。
