Abstract

Cisplatin has been associated with an increased risk of arterial thromboembolic events (ATEs). However, because this association is mostly based on case reports and retrospective studies, we conducted a systemic review and meta-analysis of randomized controlled trials evaluating the incidence and risk of ATEs associated with cisplatin. Eligible studies included prospective randomized phase II and III trials evaluating cisplatin-based vs non-cisplatin-based chemotherapy in patients with solid tumors, which were identified from PubMed articles published between 1990 and 2010. Incidence rates, relative risks (RRs), and 95% confidence intervals (CIs) were calculated using a random effects model. A total of 8216 patients from 38 trials were included. Among patients treated with cisplatin-based chemotherapy, the summary incidence of ATEs was 0.67% (95% CI = 0.40% to 0.95%), and the RR of ATEs was 1.36 (95% CI = 0.86 to 2.17; P = .19). No increase in ATEs was detected in any prespecified subgroup.
