服用阿司匹林对乳腺癌患者生存获益的Meta分析(1)
摘 要:目的 采用Meta分析探讨服用阿司匹林是否改善乳腺癌患者的预后。方法 检索PubMed、EMBASE、CNKI等中外数据库中关于服用阿司匹林与乳腺癌预后关系的文献,时间截止至2018年3月,提取全因死亡及乳腺癌特异死亡的相关结果进行效应量的合并,对纳入的数据进行敏感性分析、发表偏倚分析等。所有统计分析均采用Stata12.0软件完成。结果 共纳入11篇文献,其中包括9篇队列研究及2篇巢式病例对照研究,共计乳腺癌患者36862例。Meta分析结果显示,诊断前服用阿司匹林的乳腺癌患者与未服用的患者相比,无论是总死亡率(HR=1.06,95%CI=0.78~1.43)还是肿瘤特异死亡率(HR=1.06,95%CI=0.66~1.69)均无显著改善。诊断后服用阿司匹林并不能降低乳腺癌患者的总死亡率(HR=0.84,95%CI=0.64~1.11),但可降低肿瘤特异死亡率(HR=0.73,95%CI=0.55~0.98)。对纳入文献进行敏感性分析,结果显示,诊断后服用阿司匹林并不能降低肿瘤特异死亡率(HR=0.95,95%CI=0.85~1.06)。结论 服用阿司匹林对改善乳腺癌患者的死亡率无显著作用。

Abstract:Objective To investigate whether taking aspirin improves the prognosis of breast cancer patients by meta-analysis. Methods The literatures on the relationship between aspirin and breast cancer prognosis in PubMed,EMBASE,CNKI and other Chinese and foreign databases were searched.The results of the combination of all-cause death and breast cancer-specific death were combined until March 2018.The data is subjected to sensitivity analysis,publication bias analysis,and the like.All statistical analyses were performed using Stata 12.0 software.Results A total of 11 articles were included,including 9 cohort studies and 2 nested case-control studies,with a total of 36,862 breast cancer patients.Meta analysis showed that there was no significant improvement in total mortality(HR=1.06,95%CI=0.78~1.43)or tumor specific mortality(HR=1.06,95%CI=0.66~1.69)in patients with breast cancer who took aspirin before diagnosis compared with those who did not.Taking aspirin after diagnosis did not reduce the overall mortality of breast cancer patients(HR=0.84,95%CI=0.64~1.11),but reduced tumor-specific mortality(HR=0.73,95%CI=0.55~0.98).Sensitivity analysis of the included literature showed that taking aspirin after diagnosis did not reduce tumor-specific mortality(HR=0.95,95%CI=0.85~1.06). Conclusion Taking aspirin has no significant effect on improving mortality in breast cancer patients.

乳腺癌(breast cancer)是女性常见的恶性肿瘤,是影响人类健康的重大公共卫生问题。自从20世纪90年代以来,中国乳腺癌发病率的增长速度达到了全球增长速度的2倍,已居于我国女性恶性肿瘤发病率第一位[1,2],全世界每年死于乳腺癌的人数居女性恶性肿瘤死亡人数的第二位,每年有超过50万名女性死于乳腺癌,其中中國占9.6%[1,3]。过去的30年间,越来越多的研究表明,阿司匹林可以降低结直肠癌、乳腺癌、食管癌、胃癌和子宫内膜癌等多种癌症的发病率和死亡率[4-6],2016年4月12日,美国预防服务工作组(USPSTF)发表新的指南中,将阿司匹林作为心血管疾病和结直肠癌的一级预防药物,但对于使用阿司匹林是否改善乳腺癌患者预后的研究结果目前尚未统一,有相关研究表明诊断后口服阿司匹林能够降低乳腺癌死亡率[7-9],相反,有研究显示诊断前服用阿司匹林能增加乳腺癌死亡率[10]。阿司匹林是经典的非甾体类抗炎药(NSAID),主要用于解热、镇痛、抗炎,目前还被广泛应用于预防心脑血管疾病。对于阿司匹林抗肿瘤机制目前并不十分明确,其中最被认可的机制是抑制体内环氧化酶(COX)活性[11],COX是合成前列腺素(PG)的关键酶,通过降低PG合成,进而抑制乳腺癌细胞增殖、浸润转移及肿瘤新生血管形成[12]。此外,阿司匹林还能有效抑制血小板聚集,改善肿瘤患者的血液高凝高黏状态,预防血栓形成,降低肿瘤患者发生栓塞的危险性。因此,本研究通过Meta分析的方法,探讨服用阿司匹林是否改善乳腺癌患者的预后。, 百拇医药(张艳萍 曹玉 孙国平)
