Abstract

BACKGROUND: Icotinib is the first self-developed small molecular drug in China for targeted therapy of lung cancer. Compared to the other two commercially available epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, gefitinib and erlotinib, icotinib is similar to them in chemical structure, mechanism of activity and therapeutic effects. To explore the efficacy and side effects of icotinib hydrochloride in the treatment of the advanced non-small cell lung cancer (NSCLC) patients with EGFR mutation and wild-type.
METHODS: Patients with advanced NSCLC who were treated with icotinib hydrochloride in Beijing Chest Hospital were retrospective analyzed from March 2009 to December 2014.
RESULTS: The clinical data of 124 patients (99 with EGFR mutation and 25 with wild type) with advanced NSCLC were enrolled in this study. The patients' overall objective response rate (ORR) was 51.6 % and the disease control rate (DCR) was 79.8%; The patients with EGFR mutation, ORR was 63.6%, DCR was 93.9%. The ORR was 4.0% and the DCR was 24.0% in the wild-type patients. Median progression-free survival (PFS) with icotinib treatment in EGFR mutation patients was 10.5 months and 1.0 month in wild-type patients. The major adverse events were mild skin rash (30.6%) and diarrhea (16.1%).
CONCLUSIONS: Monotherapy with icotinib hydrochloride is effective and tolerable for the advanced NSCLC EGFR mutation patients.

目前,肺癌的发病率和死亡率在世界范围内居癌症之首。据《中国2011年恶性肿瘤登记年报》报告,2011年我国肺癌发病率为48.32/10万,死亡率为39.27/10万。发病率和死亡率均居恶性肿瘤的首位[。其中80%-85%为非小细胞肺癌(non-small cell lung cancer, NSCLC),且多数患者确诊时已处于晚期(Ⅲb期或Ⅳ期)。化疗是晚期NSCLC的主要治疗手段,但疗效已达平台期。近年来,越来越多的与肺癌相关的驱动基因被发现,相关的靶向药物被应用于临床,小分子靶向治疗药物的出现对NSCLC的治疗具有里程碑性的意义,它使NSCLC的治疗进入了个体化治疗模式。吉非替尼及厄洛替尼现已广泛应用于晚期NSCLC的治疗,并取得较好的效果。盐酸埃克替尼是一种高效特异性的表皮生长因子受体(epidermal growth factor receptor, EGFR)酪氨酸激酶抑制剂(tyrosine kinase inhibitor, TKI),是我国第一个具有自主知识产权的小分子靶向抗癌新药,与吉非替尼和厄洛替尼相比,在化学结构、分子作用机理、疗效等方面类似,但具有更好的安全性,适用于晚期NSCLC患者的治疗[。我们应用盐酸埃克替尼治疗124例EGFR突变明确的晚期NSCLC患者,并分析其临床疗效及药物相关的毒副反应。

材料与方法

临床资料

选取2009年3月-2014年12月首都医科大学附属北京胸科医院肿瘤科收治的晚期Ⅲb期或Ⅳ期NSCLC患者,所有患者均经组织学证实为NSCLC,具有完整资料。治疗前患者的血常规、肝肾功能及心功能均正常; 有可测量的临床病灶; 在治疗期间未同时行其他全身抗肿瘤治疗。

EGFR基因突变检测

全组患者均进行了肿瘤组织的EGFR基因突变检测,检测方法为扩增突变阻滞系统。EGFR基因检测时间均为一线治疗前。

治疗方法

全组患者均口服盐酸埃克替尼125 mg,3次/日,一直服用至疾病进展或毒副反应不能耐受为止。

评价标准

按照实体瘤疗效评价标准(Response Evaluation Criteria in Solid Tumors, RECIST)1.1版进行疗效判定,按照美国国立癌症研究所通用毒性标准4.0版评价毒副反应。疗效分为完全缓解(complete response, CR)、部分缓解(partial response, PR)、疾病稳定(stable disease, SD)和疾病进展(progressive disease, PD)。ORR包括CR和PR患者,DCR包括CR、PR和SD患者。

随访

124例患者均获得随访,通过门诊或电话随访获得患者的PFS,末次随访时间为2015年3月1日。PFS指患者自开始埃克替尼治疗到明确疾病进展的时间。

统计学方法

应用SPSS 22.0统计软件进行数据处理及统计分析,组间疗效和不良反应率比较应用χ2检验,Kaplane-Meier法分析患者的PFS,P < 0.05为差异有统计学意义。

讨论

EURTAC[、OPTIMAL[、WJTOG3405[等多项大型的国际多中心随机对照临床研究均证实对于EGFR敏感突变的晚期NSCLC患者,EGFR-TKI治疗的PFS及ORR均优于传统细胞毒药物的化疗。盐酸埃克替尼作为第一代小分子的EGFR-TKI,在治疗晚期NSCLC方面,与吉非替尼和厄洛替尼相同,EGFR突变状态是其独立的疗效预测因素。ICOGEN研究[显示,埃克替尼和吉非替尼均可明显改善NSCLC患者的生活质量,且差异无统计学意义; 但埃克替尼总不良反应发生率低于吉非替尼。本组124例患者均已知EGFR突变状态,99例突变患者的ORR为63.6%,DCR为93.9%,中位PFS为10.5个月,与ICOGEN研究中埃克替尼治疗突变患者的亚组分析结果(ORR:62.1%,DCR:86.2%,中位PFS为7.8个月)相似。本研究中25例野生型患者选择埃克替尼治疗的原因是患者及家属拒绝化疗、PS评分无法耐受化疗或在EGFR基因检测结果尚未回报时已经开始治疗,ORR为4.0%,DCR为24.0%,PFS仅1.0个月,ICOGEN研究中吉非替尼及埃克替尼治疗EGFR野生型患者的ORR分别为:5.1%和3.8%,BR21研究[中,厄洛替尼治疗EGFR野生型患者的ORR为7.0%,结果均相似。在既往的临床研究中,有极少部分EGFR野生型患者应用EGFR-TKI治疗有效,可能与肿瘤异质性、检测的假阴性或化疗后EGFR突变状态的改变及可能同时存在其他少见的未知EGFR-TKI敏感性分子生物学机制有关。 19外显子缺失和21外显子L858R错义突变约占EGFR总体突变的85.0%,是EGFR-TKI的敏感突变[。WJTOG3405[、ICOGEN[及IPASS[研究结果显示19外显子缺失突变的患者接受EGFR-TKI治疗时疗效好于外显子21L858R突变的患者,本组得到同样结果,两组的ORR差异有统计学意义(P=0.012),虽然两组的PFS的差别未达到统计学差异,但19外显子缺失的PFS明显长于21外显子点突变的PFS(14.0个月vs 6.0个月)。Lee等[在2015年发表了一篇meta分析,关于化疗与EGFR-TKI一线治疗EGFR突变的晚期非小细胞肺癌的疗效比较,纳入了NEJ002、EURTAC、LUXLUNG6在内的8个临床研究,共计1, 649例患者,亚组分析结果显示:19外显子缺失突变较21外显子L858R突变有更长的PFS(11.8个月vs 10.0个月),差异有统计学意义(HR=1.39; 95%CI: 1.10-1.76; P=0.006),19外显子缺失突变人群更能从EGFR-TKI治疗中获益,可能对肿瘤信号传导通路的不同作用相关。韩国学者[对306例EGFR突变患者中复合突变的发生率及EGFR-TKI的疗效进行研究,结果显示复合突变的发生率在7.3%,19外显子缺失突变与21外显子L858R错义突变的复合突变疗效最好(ORR:74.8%,PFS:11.9个月),复合突变中包含有19外显子缺失突变或21外显子L858R错义突变者次之(ORR:68.8%,PFS:8.1个月)。日本的一项研究[显示复合突变发生率为9.0%,19外显子缺失突变与21外显子L858R错义突变的复合突变应用吉非替尼治疗ORR为86.0%,中位PFS达16.5个月。本研究中有3例患者为复合突变(3.0%),1例为19外显子缺失突变和21外显子L858R点突变,1例为20外显子S768I点突变和21外显子L858R点突变,两例疗效均为PR,PFS都超过10.0个月,1例20和21外显子复合突变的PFS为4.0个月,与日韩的研究结果相似。 既往多项研究证实针对EGFR突变人群,EGFR-TKI初治和复治的疗效相近,埃克替尼上市后的ISAFE临床研究[的亚组分析显示,在EGFR突变人群中,一线治疗与复治的ORR无统计学差异(P=0.215)。本组结果虽然一线与复治相比ORR、DCR及PFS均无统计学差异,但一线治疗的ORR及PFS均好于复治患者(70.9% vs 52.4%;12.9个月vs 7.5个月),考虑可能与本组EGFR突变检测均为一线治疗前,二线及二线以上患者未行疾病进展后的复测,EGFR基因的突变状态可能在化疗后及疾病进展过程中发生变化有关。本组针对已知突变人群的PFS的单因素分析显示,腺癌与非腺癌相比,PFS的差异较大(10.8个月vs 4.0个月),但尚未达到统计学差异,与非腺癌患者病例数较少相关,需要进一步进行相关研究。 INFORM研究[和SATURN研究[确立了EGFR-TKI在晚期NSCLC维持治疗中的地位。本研究中,一线化疗后维持治疗的2例患者,一线化疗的疗效均为SD,维持治疗的疗效为PR,其中1例为20外显子S768I点突变和21外显子L858R点突变,到随访结束PFS已经达到39.5个月,现仍服药中,提示埃克替尼在EGFR突变敏感人群中维持治疗有较好疗效,但病例数较少,仍需进一步研究证实。 本研究显示,盐酸埃克替尼治疗后,患者临床症状有所改善,症状缓解中位起效时间多为10 d-14 d,缓解程度较明显,主要缓解的症状为咳嗽、喘憋、疼痛和声嘶等。 本组盐酸埃克替尼的主要不良反应为皮疹和腹泻,发生率分别为:30.6%和16.1%,均为Ⅰ度和Ⅱ度。其他少见不良反应为转氨酶升高、恶心、轻度胃部不适、皮肤瘙痒、干燥和甲沟炎等,以上不良反应的发生率及严重程度与ICOGEN研究[及近期的研究[数据相似,其发生率及皮疹的严重程度均低于吉非替尼[,更低于厄洛替尼[,埃克替尼的不良反应较轻,耐受性较好。 综上所述,盐酸埃克替尼治疗EGFR敏感突变的晚期NSCLC疗效肯定,可应用于各线治疗及维持治疗。盐酸埃克替尼治疗后患者症状缓解快,缓解程度明显,治疗相关的毒副反应较轻,患者耐受性好。
