Abstract

背景与目的晚期非小细胞肺癌(non-small cell lung cancer, NSCLC)患者根据指南应接受一线和二线的标准治疗,但出现疾病进展后的三线及三线以上治疗没有推荐,医师根据自己的经验给予治疗。本研究观察了长春瑞滨联合异环磷酰胺在晚期NSCLC三线及三线以上治疗的疗效和不良反应。方法回顾近4年北京协和医院住院使用长春瑞滨联合异环磷酰胺治疗的患者,满足以下条件:经细胞学或组织病理学证实的NSCLC,既往至少2个化疗或分子靶向治疗后进展,临床上有可测量病灶,美国东部肿瘤协作组(Eastern Cooperative Oncology Group, ECOG)体能状态评分(performance status, PS)0分-2分,无血液系统、肝肾功能异常。按照世界卫生组织(World Health Organization, WHO)标准评价患者近期疗效,根据不良事件分级标准(Common Terminology Criteria for Adverse Events, CTCAE)V4.03标准评价不良事件,随访无疾病进展时间及生存期。结果符合条件患者41例,共进行150周期化疗,其中23周期(15.3%)出现用药推迟或剂量调整。部分缓解3例(7.3%),病情稳定25例(61.0%)。中位无进展生存时间5.5个月,中位生存期为10.5个月。血液学异常是最常见的不良反应,3度/4度中性粒细胞下降10.7%,白细胞下降8.7%,血红蛋白下降8.7%。3度/4度非血液学不良反应少见。所有不良反应可以控制,无相关死亡事件。结论长春瑞滨联合和异环磷酰胺方案在晚期NSCLC三线及三线以上治疗中安全性较好,同时多数患者可获得一定疗效,但需要进一步大样本的临床试验来证实可否延长总生存期。
