CANCER EPIDEM BIOMAR:每天服用低剂量阿司匹林或降低胰腺癌风险

2016-12-23 生物探索 生物探索

导读 这两个月,科学家们找对了阿司匹林对抗癌症的多项证据。继科学家们证实,阿司匹林减缓结肠癌和胰腺癌细胞扩散的作用与血小板有关后,一项基于中国人的研究表明,每天服用低剂量的阿司匹林可能会降低患胰腺癌的风险。

导读 这两个月,科学家们找对了阿司匹林对抗癌症的多项证据。继科学家们证实,阿司匹林减缓结肠癌和胰腺癌细胞扩散的作用与血小板有关后,一项基于中国人的研究表明,每天服用低剂量的阿司匹林可能会降低患胰腺癌的风险。


12月20日,发表在Cancer Epidemiology, Biomarkers & Prevention上的一项新研究表明,每天服用低剂量的阿司匹林可能会降低患胰腺癌的风险。

尽管这项基于中国人的研究不能证明因果关系,但领导该研究的Harvey Risch博士表示,证据显示,使用阿司匹林降低心血管疾病或结肠直肠癌风险的人能够感觉到积极的作用,即,使用阿司匹林可能也降低了患胰腺癌的风险。

具体来说,2006-2011年间,这一研究追踪了上海被诊断为胰腺癌的761名患者,并将他们与794名未患癌症的参与者进行比较。所有的参与者都被询问是否定期服用低剂量的阿司匹林。其中,18%的非癌症患者报告他们会定期使用低剂量阿司匹林;在胰腺癌患者中,这一比例为11%。

在调整了他们的统计后,研究人员估计,阿司匹林可能降低了46%的胰腺癌风险。研究小组强调,这一研究并没有证明阿司匹林直接导致了更低的胰腺癌风险。但对一些其它研究的分析发现了相似的结果。研究人员分析了过去20年里其它18项调查阿司匹林使用与胰腺癌风险的研究,结果发现,随着阿司匹林使用增加,胰腺癌风险显著降低。

在美国癌症研究协会一份新闻稿中,Risch表示:“对一些人来说,定期服用阿司匹林也会导致并发症,因此,使用阿司匹林要咨询医生的建议。”

此外,肿瘤学家Tony Philip博士认为,这项研究仅表明,定期服用阿司匹林可能降低生活在中国的人的胰腺癌发病率,不能作出超出这一结论的任何推断。仅基于这一数据,他不会建议他的患者每天服用低剂量的阿司匹林。“但这一发现可作为未来进一步研究的基础。” Philip补充道。



阿司匹林“抗癌”的其它证据

除上述成果外,近阶段,科学家们还找到了使用阿司匹林能够对抗癌症的其它证据。11月30日,发表在American Journal of Physiology - Cell Physiology上的一项研究中(论文:Aspirin therapy reduces the ability of platelets to promote colon and pancreatic cancer cell proliferation: implications for the oncoprotein c-MYC),来自俄勒冈健康与科学大学的研究人员发现,阿司匹林能够减缓某些类型结肠癌和胰腺癌细胞的扩散。【详细

同日,发表在PLOS ONE杂志上的一项研究中(论文:The Long-Term Benefits of Increased Aspirin Use by At-Risk Americans Aged 50 and Older),南加州大学(USC)的研究人员发现,对具有高心脏病风险的老年美国人来说,每天服用低剂量的阿司匹林能够降低心脏病发作的风险,预防某些癌症和癌症相关死亡,并延长寿命,挽救患者的生命。【详细

4月26日,发表在Hepatology上一项研究中(论文:Aspirin use and the risk of cholangiocarcinoma),梅奥诊所的一个研究小组发现,阿司匹林的使用与患胆管癌的风险显著降低有关。【文献

4月20日,发表在PLOS ONE杂志上的一项研究(论文:Aspirin in the Treatment of Cancer: Reductions in Metastatic Spread and in Mortality: A Systematic Review and Meta-Analyses of Published Studies)考察了癌症治疗中低剂量阿司匹林的作用。研究人员回顾了47项相关研究的数据,结果显示,结直肠癌、乳腺癌和前列腺癌的治疗过程中服用低剂量阿司匹林的患者,死亡率降低了15-20%,转移发生率也有所降低。【详细
