根据2015年欧洲癌症大会的观点,阿司匹林可使胃肠道癌症患者的生存几率翻倍。 


荷兰莱顿大学医学中心Martine Frouws博士领导的研究团队指出,他们有越来越多的证据表明阿司匹林可用于预防和治疗癌症,且效果卓著。 

上个月,Medical News Today报道了一项研究,表明阿司匹林可以降低民众患结直肠癌的风险。而一项最近的研究指出,阿司匹林可能有助于提高乳腺癌、皮肤癌和肠道癌症患者的治疗效果。
在他们的研究中,Frouws博士和他的同事着手探究阿司匹林是如何影响胃肠道(包括直肠、结肠、食道)肿瘤患者的生存状况。这是第一项同时评估不同部位的肠道肿瘤患者状况的研究项目。 

这项研究共选取了13715名在1998-2011年之间被诊断患有胃肠道肿瘤的患者。对他们的随访时长平均达48.6个月。在这些患者中,结肠癌患者占42.8%,直肠癌患者为25.4%,食道癌患者为10.2%。 

为了探究阿司匹林是如何影响胃肠道癌症患者的生存时长的,研究人员从荷兰的乌得勒支PHARMO研究所获取了病人相关的服药信息及数据。 

“在这项研究中我们仔细分析了每个病人的每张处方,我们希望借此能够更精确地估计阿司匹林对癌症患者存活率的影响。”Frouws博士指出。 

总的来说,大约30.5%的患者在胃肠道肿瘤诊断确立之前便服用阿斯匹林,8.3%的病人在诊断确立之后服用阿司匹林,61.1%的病人不服用阿司匹林。参与者的5年存活率平均为28%。结果表明,在癌症诊断确立之前便服用阿司匹林的患者的5年存活率是诊断确立之后服用阿司匹林及不服用阿司匹林的患者的2倍。

即便在排除了包括年龄、性别、癌症、肿瘤治疗方案和其他合并症之后,该结论既然成立。
但是研究人员对阿司匹林具有抗癌作用的确切机制尚不清楚,他们认为这可能是因为其具有抗血小板的特性。肿瘤细胞(CTC)通常采用血小板来保护自身使其免受机体免疫系统的吞噬和破坏。由于阿司匹林具有抑制血小板的功能,因此破坏了CTC细胞,抑制了肿瘤的进展和对机体的侵袭。
虽然癌症患者服用阿司匹林的最佳剂量和用药时间及其对胃肠道肿瘤的持续影响需要研究人员进行更进一步的研究,但研究人员认为他们已经发现了这是一个治疗癌症的可行治疗方案,并且激起了癌症患者的生存的信心和希望。 

考虑到肿瘤治疗药物往往较为昂贵,而阿司匹林价廉且治疗效果优异,研究人员认为,这可能是治愈肿瘤的突破口。当然,还需后续进一步研究来证实阿司匹林的巨大功能。

房颤的抗凝治疗

抗凝治疗最重要,华法林是主力军 房颤中心董建增教授告诉记者,“房颤(心房颤动)可能导致多种不良后果,最严重的是房颤引发的卒中。有效的抗凝治疗是预防和降低房颤相关卒中及其血栓栓塞事件发病率的关键。抗凝治疗让血液不容易凝固,减少心脏里面血栓的形成,也就减少了血栓脱落,从而减少脑卒中的发生。” 关于抗凝治疗也有一个误区,即大众普遍认为的阿司匹林可预防卒中。阿司匹林仅能预防动脉粥样硬化相关卒中

郭艺芳:近日心血管病领域的几个热点话题

近日,心血管病领域有以下几个话题值得关注:1.SPRINT研究引起的震荡SPRINT研究的提前结束,在国内外学术界以及大众媒体引起空前关注,并再次激起了已经纠结多年的降压治疗目标值的问题。一时间,人们纷纷争论究竟应该把血压控制在140 mm Hg还是120 mm Hg。实际上,这种争论不会有结果,即便再有几项、甚至几十项研究也不会得出明确结论,因为不会有一个适合于所有高血压患者的理想目标值。不同特

PLoS One:氯吡格雷联合阿司匹林与单独应用阿司匹林对卒中的预防:meta分析

背景和目的:抗血小板治疗广泛应用与卒中的一级和二级预防。尽管氯吡格雷作为传统的抗血小板治疗的药物,但也有很多人应用氯吡格雷联合阿司匹林进行抗血小板治疗。研究人员对此进行meta分析,系统综述联合应用药物与单独应用阿司匹林单一治疗对患者卒中预防的差异。方法:在PubMed(1996.05月,2015),EMBASE(1947.05月,2015),CENTRAL(1948.05月,2015),ICTR

Int J Stroke:急性卒中或TIA患者阿司匹林或替卡格雷抗血小板治疗与预后(试验设计)

背景:缺血性卒中和短暂性脑缺血发作(TIA)急性期时,患者易再发缺血。阿司匹林是指南推荐用药,但是更加强化抗血小板的治疗可能是合理的。目的:研究人员旨在评估非严重缺血性卒中或者高危TIA发生24h后,与应用阿司匹林相比,替卡格雷是否能减少重大血管事件发生的风险。替比格雷是一种阻断P2Y12这种不需要代谢活性受体的药物。设计:应用阿司匹林或替卡格雷治疗急性卒中或者TIA患者以及患者预后(SOCRAT

阿司匹林或将被推荐用于预防癌症,但争议很大

阿司匹林或将被推荐用于预防癌症,但争议很大美国预防医学工作组(USPSTF)推荐使用低剂量的阿司匹林用于预防50-59岁老人心血管疾病及结直肠癌的发生。该建议草案仅适用于存在10%及以上10年心血管疾病风险而不会增加其出血风险的人群以及那些接受每日服用低剂量的阿司匹林,坚持至少10年而且可以生存那么久的人群。对于60-69岁存在10%以上10年心血管疾病发病风险的老人来说,可能因此会获得一个比较小
