Several meta-analyses of randomized controlled trials (RCTs) reported no association between the use of statins and the risk of cancer. However, they included open-label RCTs, which did not use placebo as a control group. This study aimed to evaluate the effect of statins on cancer risk using a meta-analysis of randomized, double-blind, placebo-controlled trials (RDBPCTs).
We searched PubMed, EMBASE, and the Cochrane Library in March 2016. Two individual authors reviewed and selected RDBPCTs based on selection criteria.
Out of 676 retrieved articles, a total of 21 RDBPCTs with 65,196 participants (32,618 in the statin group and 32,578 in the placebo group) were included in the meta-analysis. Overall, we found that there was no significant association between the use of statins and the risk of cancer (relative risk 0.97, 95% confidence interval 0.92-1.02, I = 0.0%) in a fixed-effect meta-analysis. In addition, in the subgroup meta-analyses, no beneficial effect of statins was observed when analyzed by statin type, country, follow-up period, methodological quality, underlying diseases/population, and type of cancer.
The current meta-analysis of RDBPCTs found that there was no association between the use of statins and the risk of cancer.
多项随机对照试验（RCT）的荟萃分析报告称，他汀类药物的使用与癌症风险之间没有关联。然而，这些分析纳入了开放标签的RCT，其未将安慰剂作为对照组。本研究旨在通过对随机、双盲、安慰剂对照试验（RDBPCT）进行荟萃分析，评估他汀类药物对癌症风险的影响。
我们于2016年3月检索了PubMed、EMBASE和Cochrane图书馆。两位独立作者根据选择标准对RDBPCT进行了审查和筛选。
在检索到的676篇文章中，共有21项RDBPCT纳入荟萃分析，涉及65196名参与者（他汀类药物组32618名，安慰剂组32578名）。总体而言，我们发现在固定效应荟萃分析中，他汀类药物的使用与癌症风险之间没有显著关联（相对风险0.97，95%置信区间0.92 - 1.02，I² = 0.0%）。此外，在亚组荟萃分析中，按他汀类药物类型、国家、随访期、方法学质量、基础疾病/人群和癌症类型分析时，未观察到他汀类药物有有益作用。
当前对RDBPCT的荟萃分析发现，他汀类药物的使用与癌症风险之间没有关联。
