Abstract
BackgroundIn patients with epidermal growth factor receptor (EGFR) mutated non–small-cell lung cancer (NSCLC), EGFR-tyrosine kinase inhibitor (TKI) interruption due to EGFR-TKI-induced interstitial lung disease (ILD) is a factor for shorter overall survival (OS). Several retrospective cohort studies have reported an OS-prolonging effect of the readministration of EGFR-TKIs. This study aimed to determine the safety of readministration of EGFR-TKIs after the onset of EGFR-TKI-induced ILD. MethodsThe PubMed, CINAHL, and Web of Science databases were systematically searched until May 30, 2023. The primary outcome was successful readministration of EGFR-TKIs after the onset of EGFR-TKI-induced ILD. ResultsA total of 690 patients were included in this meta-analysis. The initial EGFR-TKI-induced ILD rate was 13.6% (95% confidence interval [CI]:6.4-20.9). Readministration rate of EGFR-TKI after onset of EGFR-TKI-induced ILD was 40.2% (95% CI: 26.7-53.7). The successful readministration rate of EGFR-TKIs after onset of EGFR-TKI-induced ILD was 81.9% (95% CI: 73.8-90.0). Successful rate of EGFR-TKI readministration in patients with Grade 2 or higher adverse events post initial EGFR-TKI therapy was 76.1% (95% CI: 55.6-96.6). ConclusionsAlthough initial EGFR-TKI-induced ILD has a relatively high incidence, EGFR-TKI readministration after the onset of EGFR-TKI-induced ILD may be a viable treatment option.
