  《肿瘤学年鉴》(Ann Oncol)近期发表的一项研究表明,贝伐珠单抗治疗与转移性结直肠癌动脉血栓栓塞形成(ATE)风险较高有关,但在老年患者或伴有ATE病史或血管风险因素的患者中,贝伐珠单抗的安全性并不显著更差。此外,研究未能在接受贝伐单抗的患者中证明阿司匹林对ATE的预防作用。

  该研究来自MAX研究的471例转移性结直肠癌患者的3、4或5级ATE事件和其他数据(包括年龄、基线心血管风险因素、ATE病史和阿司匹林使用情况)。

  结果显示,接受贝伐珠单抗治疗的患者3、4或5 级ATE的发生率为3.8%。 年龄>65岁的患者、有ATE病史的患者和伴心血管风险因素患者的ATE发生率分别为2.1%、5%和5%。年龄、ATE病史或心血管风险因素并没有增加ATE风险。阿司匹林使用者ATE发生率高于未使用者(8.9% 对 2.7%),但伴有心血管风险因素患者的比例较高。
