在2013年7月1日在线出版的《临床肿瘤学杂志》(Journal of Clinical Oncology)上,我国台湾地区台湾大学肿瘤医学研究所的杨志新教授等人公布了LUX-Lung 3临床试验的最新研究成果,该研究通过一项针对阿法替尼或顺铂/培美曲塞的随机临床III期试验,对患者报告的症状及与健康相关的生活质量(QoL)获益情况进行了考察。

研究人员按2:1的比例,对345例表皮生长因子受体(EGFR)突变呈阳性的晚期肺腺癌患者进行了随机分配,患者分别接受每日40mg的阿法替尼或共计6个周期的顺铂/培美曲塞治疗。根据欧洲癌症研究与治疗组织的C30生活质量问卷调查及肺癌13问卷调查内容,每21天对患者肺癌症状及健康相关QoL进行一次评价,直至患者出现病情进展。研究还预设了针对咳嗽、呼吸困难及疼痛等方面的分析,其中包括经治疗后得到改善的患者比例、症状恶化时间以及症状随时间的变化情况等。

该问卷调查的患者依从性较高。研究发现,与化疗相比,阿法替尼可显著延缓咳嗽(风险比[HR], 0.60; 95% CI, 0.41至0.87; P = .007)及呼吸困难(HR, 0.68; 95% CI, 0.50至0.93; P = .015)症状的恶化时间,但并不能延缓疼痛(HR, 0.83; 95% CI, 0.62至1.10; P = .19)的恶化时间。与化疗患者(50%)相比,阿法替尼组(64%)中有更多患者的呼吸困难评分得到了改善(P = .010)。经过一定时间治疗后,与化疗组相比,阿法替尼组在咳嗽(P < .001)及呼吸困难症状(P < .001)的平均评分结果方面明显较好。并且经过一定时间治疗后,与化疗组相比,阿法替尼组患者在总体健康状况/QoL (P = .015)及体质 (P < .001)、功能(P = .004)及认知功能(P = .007)平均评分结果方面也明显较好。化疗组患者中,疲劳及恶心症状较为严重,而阿法替尼组中腹泻、吞咽困难及口腔发炎的症状较为严重(所有P < .01).。

研究人员最终认为,尽管存在EGFR突变的肺腺癌患者通过阿法替尼治疗可出现较为严重的腹泻、吞咽困难及口腔发炎症状,但与化疗相比,阿法替尼一线治疗与较好的咳嗽及呼吸困难控制间存在关联。同时经过一定时间的治疗后,与化疗相比,阿法替尼可改善患者的总体健康状况/QoL。

阿法替尼是一种口服、不可逆转的ErbB家族阻滞剂,能阻滞EGFR(ErbB1)、人类表皮生长因子受体2(HER2 ;ErbB2)和ErbB4的信号传导。在LUX-Lung 6研究中,结果证实与吉西他滨/顺铂方案相比,阿法替尼能显著改善患者的无进展生存期和肿瘤对治疗的反应率,同时该治疗方案的安全性也更佳。在本文中,研 究者将进一步报道该研究中患者自我结局报告(PROs)情况。研究共纳入了364名受试
