目的:探讨抗血管生成药物安罗替尼联合立体定向放射外科（stereotactic radiosurgery，SRS）治疗非小细胞肺癌脑转移的有效性和安全性。方法:纳入2017年10月至2019年6月北京大学第三医院接受SRS的46例非小细胞肺癌脑转移患者。按照治疗方式的不同分为联合治疗组（n n=21）和单独SRS组（n n=25）。联合治疗组（33处病灶）接受安罗替尼联合脑部SRS，单独SRS组（35处病灶）仅接受脑部SRS。比较分析两组患者颅内高压缓解率、颅内病灶治疗有效率、放射性脑坏死发生率及颅内无进展生存情况。记录联合治疗组安罗替尼用药情况及不良反应。n 结果:联合治疗组的颅内高压缓解率为71.4%（15/21），高于单独SRS组的12.0%（3/25）（n P<0.001）。两组患者颅内病灶治疗有效率分别为80.9%（17/21）和60.0%（15/25），差异无统计学意义（n P=0.289）。联合治疗组的放射性脑坏死发生率为3.0%（1/33），低于单独SRS组的20.0%（7/35，n P=0.030）。联合治疗组颅内无进展生存期为（13.9±2.4）个月，长于单独SRS组的（11.4±1.8）个月（n P<0.001）。联合治疗组安罗替尼用药时间为6（6，18）周。有1例患者发生Ⅰ级高血压，1例患者发生Ⅰ级手足皮肤反应，药物相关不良反应发生率为9.5%（2/21）。n 结论:安罗替尼联合SRS能够有效缓解脑水肿，降低放射性脑坏死的发生率，不良反应发生率较低。“,”Objective:To investigate the efficacy and safety of anti-vascular drug anlotinib in combination with stereotactic radiosurgery (SRS) for the treatment of brain metastases from non-small cell lung cancer (NSCLC).Methods:A total of 46 patients diagnosed with NSCLC brain metastases and treated with SRS in Peking University Third Hospital were included from October 2017 to June 2019. Of these, 21 patients (33 lesions) received anlotinib combined with SRS (combined treatment group), while 25 patients (35 lesions) only received SRS (SRS-alone group). The data of combined treatment group and SRS-alone group were compared, including remission rate of intracranial hypertension, response rate (RR) of local control of intracranial lesions, incidence of radiation-induced brain necrosis and intracranial progression-free survival (iPFS). The medication and adverse reactions of anlotinib in the combined treatment group were recorded.Results:The remission rate of intracranial hypertension in the combined treatment group was 71.4% (15/21), which was significantly higher than that in the SRS-alone group [12.0% (3/25), n P<0.001). However, the RR of combined treatment group and SRS-alone group was 80.9% (17/21) and 60.0% (15/25), respectively, with no statistically significant difference (n P=0.289). The incidence of radiation-induced brain necrosis in the combined treatment group was 3.0% (1/33), which was significantly lower than that in the SRS-alone group [20.0% (7/35), n P=0.030]. The iPFS of the combination treatment group was (13.9±2.4) months, which was significantly longer than that in the SRS-alone group [(11.4±1.8) months, n P<0.001]. The medication time of anlotinib in the combined treatment group was 6 (6, 18) weeks. One patient developed grade Ⅰ hypertension and one patient developed grade Ⅰ hand-foot syndrome. The incidence of drug-related adverse reactions was 9.5% (2/21).n Conclusions:Anlotinib in combination with SRS may relieve brain edema, reduce the rate of radiation-induced brain necrosis, and the rate of drug-related adverse reactions were low.
