Multiple studies have discussed the associations between drugs affecting the renin-angiotensin-aldosterone
system and the cancer risk, but their consequence s were conflicting. A meta-analysis of nested case-control studies
published regarding this subject was conducted in our study, aims to estimate the association between ACEI/ARB and
the cancer risk. Pubmed database was searched up to February, 1 2016 to identify eligible nested case-control studies,
and we used Newcastle-Ottawa Scale (NOS) to assess quality of the studies. Pooled odds ratio (OR) and 95% confidence
intervals (CIs) were calculated (with fixed effect model: Mantel-Haenszel). Publication bias and heterogeneity were
evaluated before the calculation. Subgroup analysis and sensitivity analysis were also performed. Seven studies
contributed to the analysis. Overall, ACEI/ARB use was not associated with the risk of cancer (OR=0.99, 95% CI 0.97-
1.01), nor in long-term use patients (OR=0.97, 95% CI 0.92-1.01). ACEI may decrease cancer risk (OR=0.90, 95% CI
0.82-0.99). We observed no significant publication bias. In conclusion, ACEI/ARB use was not associated with cancer
risk, nor in long-term use patients, but ACEI use may decrease cancer risk. More researches are needed to confirm these
findings. |
