Risk of fatal pulmonary events in patients with advanced non-small-cell lung cancer treated with EGF receptor tyrosine kinase inhibitors: a comparative meta-analysis

Abstract

ABSTRACT  We performed a meta-analysis of fatal pulmonary events associated with erlotinib, gefitinib or afatinib in patients with non-small-cell lung cancer (NSCLC). Eligible studies included randomized trials of patients with NSCLC on the three drugs describing events of high-grade pulmonary events. The relative risk of high-grade interstitial lung disease, pneumonitis, pneumonia, pulmonary embolism and hemoptysis were 4.18 (95% CI: 2.49–7.01; p < 0.00001), 1.94 (95% CI: 0.93–4.06; p = 0.08), 1.28 (95% CI: 0.92–1.77; p = 0.14), 1.6 (95% CI: 0.81–3.18 p = 0.17), 1.00 (95% CI: 0.14–7.08 p = 0.35), respectively. Our meta-analysis has demonstrated that erlotinib, gefitinib and afatinib are associated with an increased risk of high-grade interstitial lung disease in patients with NSCLC.
