以前的流行病学研究表明,与洋地黄药物相关的乳腺癌风险增加,尽管结果不一致。我们对现有的流行病学研究进行了系统回顾,以阐明洋地黄的使用与乳腺癌风险之间的关系。方法检索截至2016年5月在MEDLINE和EMBASE数据库中发表的研究,并辅以人工检索参考文献列表。对纳入研究的质量进行了评估,并使用随机效应和固定效应模型汇总了相对风险。结果共纳入3项病例对照研究和6项队列研究。在固定效应和随机效应模型中,荟萃分析得出的总相对风险为1.35(95%置信区间为1.24-1.46)。异质性检验表明各研究间异质性较低。漏斗图显示不存在发表偏倚。通过研究设计进行的亚组分析显示,仅从队列研究(相对风险= 1.39,95%可信区间1.27-1.52)而不是从病例对照研究中发现,使用洋地黄与乳腺癌风险增加有关。对吸烟或体重指数进行调整的研究得出的总体估计值低于未进行调整的研究。结论现有的流行病学证据表明洋地黄的使用与乳腺癌风险之间的关系仍不具有结论性,仍需要更多精心设计的研究。
IntroductionPrevious epidemiological studies have indicated an increased risk of breast cancer associated with digitalis medication, though results are inconsistent. We performed this systematic review of available epidemiological studies to clarify the association between digitalis use and the risk of breast cancer.MethodsA search of studies published through May 2016 in MEDLINE and EMBASE databases was performed, supplemented by manual searches of reference lists. The quality of the included studies was assessed, and relative risks were pooled using both random- and fixed-effect models.ResultsThree case–control studies and six cohort studies were identified. Meta-analysis generated a pooled relative risk of 1.35 (95% confidence interval 1.24–1.46) in both fixed- and random-effect models. The heterogeneity test suggested low heterogeneity across studies. The funnel plot suggested no existence of publication bias. Subgroup analysis by study design revealed an increased risk of breast cancer associated with digitalis use from cohort studies only (relative risk = 1.39, 95% confidence interval 1.27–1.52), rather than from case–control studies. Studies with adjustment for tobacco smoking or body mass index generated lower overall estimates than those not adjusted.ConclusionsExisting epidemiological evidence regarding the association between digitalis use and the risk of breast cancer remains inconclusive and more well-designed studies are still needed.
