摘 要:目的本研究旨在评价埃克替尼在复治晚期肺腺癌患者的近期疗效与安全性。方法回顾性分析2011年8月~2012年2月在浙江省肿瘤医院就诊的51例曾经接受过一线或一线以上化疗方案治疗失败的Ⅳ期的肺腺癌患者,给予埃克替尼治疗(125mg口服,每日3次)直至疾病进展。卡方检验比较不同因素在缓解率及疾病控制率方面有无差异,Kaplan—Meier法进行生存分析和比较。结果51例患者中12例患者达到部分缓解(partialresponse,PR)(23.5%),27例患者达到疾病稳定(stabledisease,SD)(52.9%),客观缓解率(objectiveresponserate,ORR)达到23.5%,疾病控制率(diseasecontrolrate,DCR)达到76.5%。患者中位无进展生存期(medianprogression—freesurvival,mPFS)为5.13个月(95%CI:0.41~9.90),自服用埃克替尼直至死亡的中位生存期(medianoverallsurvival,mOS)为12.47个月(95%CI:10.06—14.88)。常见的不良反应为皮疹和腹泻,大部分为轻到中度。结论埃克替尼可以有效治疗复治晚期肺腺癌患者,且耐受性良好。Objective To evaluate the efficacy and side effects of icotinib on patients with advanced adenocarcinoma lung cancer. Methods Totally 51 patients with advanced adenocarcinoma lung cancer who had progressed after chemotherapy receiving icotinib (125rag po tid) were retrospectively analyzed from August, 2011 to February, 2012. Kaplan - Meier was used to analysis survival and comparison. Results Among the 51 patients, 12 patients got partial response (23.5%) , 27 stable disease(52.9% ). The objective re- sponse rate was 23.5% and disease control rate including both tumor response and stable disease was76.5% ,and progression -free sur- vival (PFS) was 5.13 month (95% CI:0.41 -9.90). The overall survival (OS) of patients starting the treatment of icotinib was 12.47 month(95% CI:10.06- 14.88). The main toxicity of icotinib was skin toxicity(rash) and diarrhea. Most of drug- related adverse event were mild. Conclusion Icotinib demonstrates significant antitumor activity and a favorable tolerability profile in adenocarcinoma lung cancer.
