JAMA Intern Med:华法林可大幅降低50岁以上人群的肿瘤风险!

2017-11-13 zhangfan MedSci原创

研究认为对于50岁以上人群华法林具有广泛的抗肿瘤活性,这一发现可能对需要抗凝治疗的患者的药物选择具有重要意义

临床前研究显示,低于抗凝剂量的华法林可抑制AXL受体酪氨酸激酶依赖性肿瘤的发生并增强抗肿瘤免疫反应。近日研究人员对华法林的抗肿瘤效果进行大规模的人群队列研究。

研究在挪威开展,1924-1954年间出生的1256725人参与。队列分为2组,华法林使用组或未使用组,服用华法林治疗心房颤动或心房扑动者患者单独进行考察。定义华法林使用者为至少服药6个月且在肿瘤诊断前2年开始服药。研究的主要终点是试验期间的肿瘤发生率。

所有参与者中,男性占48.3%,10.6%的患者发生肿瘤,7.4%的参与者定义为华法林使用者。华法林使用者年龄较大,平均年龄为70.2岁,男性比例较高(61.7%)。研究发现,相比于未使用者,华法林组参试人员,所有肿瘤的年龄和性别调整后发病率降低(IRR,0.84; 95% CI,0.82-0.86),部分特异组织肿瘤发病率降低。(肺,0.80 [95% CI,0.75-0.86]; 前列腺,0.69 [95% CI,0.65-0.72]以及乳腺,0.90 [95% CI,0.82-1.00]),但结肠癌的发病率无显著变化 (IRR,0.99;95% CI,0.93-1.06)。亚组分析显示,接受华法林治疗的心房颤动或心房扑动者患者所有肿瘤(IRR, 0.62; 95% CI,0.59-0.65)和部分位点特异性肿瘤(肺,0.39 [95% CI,0.33-0.46];前列腺,0.60 [95% CI,0.55-0.66];乳腺,0.72 [95% CI,0.59-0.87];结肠,0.71 [95% CI,0.63-0.81])的发病率降低。

研究认为对于50岁以上人群华法林具有广泛的抗肿瘤活性,这一发现可能对需要抗凝治疗的患者的药物选择具有重要意义。
