Abstract

背景与目的吉非替尼和培美曲塞均是晚期非小细胞肺癌(non-small cell lung cancer, NSCLC)二线治疗的药物,但直接对比两者二线治疗的研究数据有限。本研究旨在比较吉非替尼和培美曲塞二线治疗晚期非鳞型NSCLC的疗效、安全性及对生活质量的影响。方法将46例一线含铂双药化疗方案(不含培美曲塞)治疗失败的晚期非鳞型NSCLC患者随机分为两组,每组23例,分别给予吉非替尼口服(吉非替尼组),或静脉滴注培美曲塞(培美曲塞组),比较两组的疗效和安全性及治疗对生活质量的影响。结果培美曲塞组的客观缓解率(objective response rate, ORR)为13.0%(3/23),疾病控制率(disease control rate, DCR)为30.4%(7/23),中位无进展生存时间(median progression-free survival, mPFS)为3.1个月;吉非替尼组的ORR 17.3%(4/23),DCR 39.1%(9/23),mPFS 4.4个月;两组的ORR、DCR和mPFS均未见统计学差异(P > 0.05)。培美曲塞最常见的不良反应为中性粒细胞减少(n=9, 39.13%)和乏力(n=8, 34.78%);吉非替尼最常见的不良反应为皮疹(n=8, 34.78%)和腹泻(n=4, 17.39%)。和治疗前基线相比,培美曲塞组和吉非替尼组治疗后生活质量评分均有不同程度的改善,吉非替尼组在情绪,活动能力及肺癌附加关注的其它因素方面较培美曲塞组改善更明显(P < 0.05)。结论吉非替尼和培美曲塞二线治疗晚期非鳞型NSCLC的疗效相似,不良反应各异;两者均能改善患者的生活质量,但是吉非替尼改善更明显。
