Breast Cancer Res:“神药”阿司匹林的又一大有益功效被证实

一项由希望市主导的研究发现,使用低剂量阿司匹林(81mg)降低了加州教师研究中妇女乳腺癌的风险。本研究首次提出低剂量阿司匹林降低乳腺癌风险 - 由希望市早期检测和预防生物标志物教授和主任莱斯利伯恩斯坦博士提名,在线刊登在乳腺癌研究杂志上。

一项由希望市主导的研究发现,使用低剂量阿司匹林(81mg)降低了加州教师研究中妇女乳腺癌的风险。本研究首次提出低剂量阿司匹林降低乳腺癌风险 - 由希望市早期检测和预防生物标志物教授和主任莱斯利伯恩斯坦博士提名,在线刊登在乳腺癌研究杂志上。

伯恩斯坦和她的同事们观察到,在报告每周至少使用低剂量阿司匹林三次的女性中,总共降低了16%的乳腺癌风险。这种经常的低剂量阿司匹林的使用使雌激素或孕激素受体阳性的风险降低了20%,HER2阴性乳腺癌是最常见的乳腺癌亚型。

来自加利福尼亚癌症预防研究所的首席研究人员克里斯蒂娜·克拉克博士,M.P.H.博士说:“研究发现低剂量阿司匹林和乳腺癌之间有趣的保护性关联。 “我们并没有发现乳腺癌与其他止痛药物如布洛芬和对乙酰氨基酚有关联,我们也没有发现它与常规阿司匹林有关联,因为这种类型的药物偶尔服用于头痛或其他疼痛,而不是每天用于预防心血管疾病“。

这项研究与其他研究阿司匹林和癌症风险的研究不同,因为它集中在阿司匹林妇女服用的剂量水平,并跟踪使用低剂量阿司匹林而不是常规阿司匹林的频率。它也能够详细地查看乳腺癌的亚型。

伯恩斯坦说:“我们已经知道,阿司匹林是一种微弱的芳香酶抑制剂,我们用更强的芳香酶抑制剂治疗乳腺癌妇女,因为它们减少了绝经后雌激素在血液中循环的数量。 “我们认为如果阿司匹林可以抑制芳香酶,那么应该减少乳腺癌发展的可能性,而且一旦不再服用更有效的芳香酶抑制剂,它也可以成为改善乳腺癌患者预后的有效途径。”伯恩斯坦补充说:“阿司匹林还可以减少炎症,这可能是阿司匹林定期服用降低乳腺癌发展或复发的风险的另一种机制。”

作为研究的一部分,研究人员分析了加利福尼亚“教师研究”中57,164名妇女提交的问卷调查数据。 2005年,参与者回答了有关癌症家族史和其他病症,使用阿司匹林和其他非甾体抗炎药(NSAIDS),月经和生殖史,使用激素,体重和身高,生活环境,饮食,酒精使用等问题。在接下来2013年之前,这些参与者中有1,457人发展成侵袭性乳腺癌。

研究人员团队选择专注于低剂量的“宝宝”阿司匹林,因为它不仅价格便宜,而且作为预防手段容易获得,而且因为已有很多人已经采取预防其他疾病,例如心脏病甚至结肠癌

现在我们有一些低剂量阿司匹林的数据,可以进行更详细的研究,以了解低剂量阿司匹林对预防乳腺癌的全部价值。“克拉克说。
