Non-steroidal anti-inflammatory drugs are a risk factor for cisplatin-induced nephrotoxicity: A meta-analysis of retrospective studies

Background/Aim: Previous reports have demonstrated that non-steroidal anti-inflammatory drugs (NSAIDs) are a risk factor for cisplatin-induced nephrotoxicity (CIN). Here, the results of these previous studies were comprehensively assessed via a meta-analysis. Materials and Methods: After a database search to select eligible studies, a meta-analysis was performed using a forest plot, followed by an assessment of the heterogeneity and publication bias and a subgroup analysis. Results: Seven studies were extracted as candidates. All were retrospective studies and evaluated the effect of NSAIDs on CIN as a secondary endpoint. According to the meta-analysis, total odds ratio was 1.88 (95% confidence interval=1.44-2.45). Further, high heterogeneity and publication bias were not observed. A subgroup analysis of the chemotherapy evaluation period revealed that CIN tended to be enhanced in the first course group (evaluation in only 1 course) and was significantly enhanced in the total course group (evaluation in 1 or more courses) by NSAIDs coadministration. Conclusion: NSAIDs co-administration could be a risk factor for CIN.
