摘要 目的观察盐酸埃克替尼治疗晚期非小细胞肺癌(NSCLC)的近期疗效和毒副反应。方法回顾性分析2009年3月至2012年1月间收治的晚期NSCLC患者59例,均口服盐酸埃克替尼单药治疗,评价其近期疗效和毒副反应。全组有25例患者行表皮生长因子受体(EGFR)基因检测,其中19外显子缺失突变13例,21外显子错义突变9例,20和21外显子双突变1例,EGFR野生型2例。结果59例NSCLC患者中,部分缓解27例(45.8%),疾病稳定17例(28.8%),疾病进展15例(25.4%),客观有效率为45.8%(27/59),疾病控制率为74.6%(44/59)。EGFR突变患者的客观有效率为73.9%(17/23),疾病控制率为95.7%(22/23)。59例患者中,有36例(61.0%)患者在治疗后有不同程度的症状缓解,主要缓解的症状为咳嗽、喘憋、疼痛和声嘶等。治疗相关毒副反应主要为皮疹21例(35.6%),其中I度18例,Ⅱ度2例,Ⅲ度1例;腹泻9例(15.3%),其中Ⅰ度7例,Ⅱ度2例;其他不良反应为皮肤干燥、恶心和胃部不适等。盐酸埃克替尼治疗的疗效与美国东部肿瘤协作组(ECOG)评分、治疗方式、吸烟史、EGFR突变、皮疹有关,差异有统计学意义(P〈0.05)。结论盐酸埃克替尼单药治疗晚期NSCLC近期疗效肯定,对于EGFR突变患者有效率更高,治疗相关的毒副反应较轻,患者耐受性好,为晚期NSCLC患者治疗的新选择。 Objective To explore the efficacy and side effects of icotinib hydrochloride in the treatment of patients with advanced non-small cell lung cancer (NSCLC). Methods The efficacy and side effects of ieotinib hydrochloride in treatment of 59 cases with stage 1V NSCIC and followed-up from March 2009 to January 2012 were retrospectively analyzed. Results Twenty seven patients (45.8%) showed partial response (PR) , 17 patients (28.8%) achieved SD, and 15 (25.4%) had progressive disease. The objective response rate (ORR) was 45.8 % ( 27/59 ), and disease control rate (DCR) was 74.6% (44/59). Among the 23 patients with EGFR mutation, ORR was 73.9 % ( 17/23 ), and DCR was 95.7% (22/23). Thirty six patients ( 61.0% ) achieved remission of symptoms to varying degrees. The main symptoms relieved were cough, asthmatic suffocating, pain and hoarseness. The major adverse events were mild skin rash (35.6%) and diarrhea (15.3%). Others were dry skin, nausea and stomach problems. The efficacy of icotinib hydrochloride were related to the ECOG performance status, smoking history, EGFR mutation and rash significantly ( P 〈 0. 05 ). Conclusions Monotherapy with icotinib hydrochloride is effective and tolerable for patients with advanced NSCLC, especially with EGFR mutation.
