阿来替尼治疗ALK基因融合重排NSCLC脑转移瘤的临床疗效分析

  目的  探讨阿来替尼治疗ALK融合重排非小细胞肺癌（non-small cell lung cance，NSCLC）脑转移患者的疗效及不良反应。  方法  回顾性分析2016年8月至2019年10月天津医科大学肿瘤医院34例以脑转移为首发的ALK基因融合重排NSCLC患者的临床资料，其中13例（38.2%）患者接受阿来替尼单药一线治疗。男性7例（53.8%），女性6例（46.2%），中位年龄51（35~72）岁。应用Kaplan-Meier分析其生存情况。  结果  阿来替尼治疗ALK基因融合重排肺癌脑转移瘤，颅内中位无进展生存期（median progression-free survival，mPFS）为24.5个月。药物不良反应较轻。  结论  在颅内可测量病灶得到局部治疗的基础上，阿来替尼作为ALK基因融合重排NSCLC脑转移患者的一线治疗方案，显著延长患者无进展生存期（progression-free survival，PFS）。 

Efficacy of alectinib for ALK-positive NSCLC brain metastases

  Objective   To investigate the effect of alectinib in the treatment of brain metastases from anaplastic lymphoma kinase(ALK)- positive non-small cell lung cancer (NSCLC).   Methods   Thirty-four cases of ALK-positive NSCLC in Tianjin Medical University Cancer Institute and Hospital, between August 2016 to October 2019, were retrospectively analyzed. Thirteen cases received first-line single drug therapy (600 mg PO bid) of Alectinib. 7 cases (53.8%) were male, 6 cases were female (46.2%), the median age was 51 (35-72). The Kaplan-Meier method was used to examine progression-free survival (PFS).   Results   The median progression-free survival (mPFS) of the alectinib group was 24.5 months, and the adverse drug reactions were mild.   Conclusions   The use of alectinibas first-line treatment after the local treatment of measurable intracranial lesions significantly increased the PFS of patients with brain metastases from ALK-positive NSCLC.
