Risk and Incidence of Infection with Bevacizumab in Non-Small-Cell Lung Cancer Patients: A Meta-Analysis

Abstract

Background: A previous meta-analysis suggested that use of bevacizumab is associated with an increased risk of infection in cancer patients. With the continuous accumulation of evidence in non-small-cell lung cancer (NSCLC), we performed a new, focused meta-analysis of randomized controlled trials (RCTs) to quantify the relative risk (RR) and incidence of infectious complications in those individuals treated with bevacizumab. Methods: Electronic databases were searched, including PubMed, Embase, and Cochrane databases. Eligible studies were prospective randomized clinical trials of NSCLC patients treated with bevacizumab with toxicity data on infectious complications. RR, overall incidence rates, and 95% confidence intervals (CI) were calculated using fixed- or random-effects models, depending on the heterogeneity of the included studies. Results: A total of 4,545 patients from 14 prospective RCTs were included in the meta-analysis. Treatment with bevacizumab was not associated with an increased risk of all-grade (RR 1.12, 95% CI: 0.84-1.49) or high-grade (RR 1.11, 95% CI: 0.86-1.41) infections, respectively. The summary incidences of all-grade and high-grade infections in patients receiving bevacizumab in the treatment group were 16.4% (95% CI: 15.7-17.2%) and 4.3% (95% CI: 3.0-6.1%), respectively. Conclusions: The use of bevacizumab is not associated with a significantly higher risk of infections in NSCLC patients. These data provide reassurance regarding the risk of infection in patients with NSCLC receiving bevacizumab.
