J Thromb Haemost:直接口服抗凝药会增加脑肿瘤患者颅内出血风险吗?

2019年1月,发表于《J Thromb Haemost》上的一项研究,考察了脑肿瘤患者直接口服抗凝药(DOACs)的颅内出血(ICH)风险。

2019年1月,发表于《J Thromb Haemost》上的一项研究,考察了脑肿瘤患者直接口服抗凝药(DOACs)的颅内出血(ICH)风险。

概要:ICH在脑肿瘤患者中是常见的。研究者比较DOACs和低分子量肝素(LMWH)的ICH率。在原发性脑肿瘤中,DOACs与较低的ICH率相关。DOACs似乎对于脑肿瘤患者是安全的。

背景:DOACs能有效治疗肿瘤相关血栓,但在某些肿瘤中,同LMWH相比,能增加出血风险。DOACs是否会增加脑肿瘤患者的ICH率仍未被证实。

目的:在脑肿瘤和静脉血栓患者中,考察DOACs同LMWH相比的累积ICH率。

患者和方法:开展了一项回顾性队列研究。回顾所有ICH事件的影像学图像,主要终点是开始抗凝治疗后12个月时ICH累积发病率。

结果:172名脑肿瘤患者被评估(42名DOAC和131名LMWH)。在颅内原发肿瘤队列中(n=67),接受DOACs患者的任何ICH累积发生率是0%,相比较LMWH治疗的患者是36.8%(95%置信区间[CI],22.3~51.3%),主要ICH发生率是18.2%(95%CI,8.4~31.0)。在脑转移队列(n=105)中,同依诺肝素相比,DOACs不会增加任何ICH风险,发生率分别为27.8%(95%CI,5.5~-56.7%) vs 52.9%(95%CI,37.4~66.2%)。相同地,DOAC不会增加脑转移中主要ICH的发生率,累积发生率为11.1%(95%CI,0.5~40.6%)vs 17.8%(95%CI,10.2~27.2%)。

结论:在脑转移或原发性脑瘤患者中,DOACs相对于LMWH与ICH发病率增加无关。
