Observational studies examining the relationship between hypertension and breast cancer risk have reported conflicting findings. We conducted this systematic review and meta-analysis to summarize the evidence regarding the association between hypertension and risk of breast cancer. Eligible studies were identified through a comprehensive literature search of PubMed, EMBASE, and the Cochrane library until August 2016. We included observational studies that reported relative risks (RR) with corresponding 95% confidence intervals (CIs). Results from individual studies were pooled by using a random-effects model. 29 articles of 30 studies, with totally 11643 cases of breast cancer, were eligible for inclusion in the meta-analysis. We observed a statistically significant association between hypertension and increased breast cancer risk (RR: 1.15; 95% CI: 1.08, 1.22). In the subgroup analysis, we found a positive association between hypertension and breast cancer incidence among postmenopausal women (RR: 1.20; 95% CI: 1.09, 1.31). In contrast, hypertension was not associated with risk of breast cancer among premenopausal women (RR: 0.97; 95% CI: 0.84, 1.12) and Asian population (RR: 1.07; 95% CI: 0.94, 1.22).This meta-analysis collectively suggests a significantly association between hypertension and breast cancer risk, specifically for postmenopausal hypertensive women.
观察性研究检查了高血压与乳腺癌风险之间的关系,报道的结果相互矛盾。我们进行了这项系统综述和荟萃分析,以总结高血压与乳腺癌风险之间关联的证据。通过对 PubMed、EMBASE 和 Cochrane 图书馆进行全面的文献检索,确定了符合条件的研究。我们纳入了报告相对风险(RR)和相应 95%置信区间(CI)的观察性研究。使用随机效应模型汇总来自各个研究的结果。纳入荟萃分析的 29 篇文章来自 30 项研究,共包括 11643 例乳腺癌病例。我们观察到高血压与乳腺癌风险增加之间存在统计学显著关联(RR:1.15;95%CI:1.08,1.22)。在亚组分析中,我们发现高血压与绝经后妇女的乳腺癌发病率之间存在正相关(RR:1.20;95%CI:1.09,1.31)。相比之下,高血压与绝经前妇女(RR:0.97;95%CI:0.84,1.12)和亚洲人群(RR:1.07;95%CI:0.94,1.22)的乳腺癌风险无关。这项荟萃分析总体表明高血压与乳腺癌风险之间存在显著关联,特别是对于绝经后高血压妇女。
