ABSTRACT
BACKGROUND:
Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are used to treat patients with non-small cell lung cancer (NSCLC) and EGFR driver mutations. Although some patients discontinued these treatments because of adverse events, it is unclear whether switching EGFR-TKI because of adverse events provides a benefit.METHODS:
This retrospective study evaluated data from 22 patients with EGFR mutation-positive NSCLC who received at least two EGFR-TKIs that were switched because of adverse events (March 2011 to September 2017). Progression-free survival 2 (PFS2) was defined as the time from starting of the first EGFR-TKI treatment to disease progression during the second EGFR-TKI treatment.RESULTS:
Seventeen patients received gefitinib as the first EGFR-TKI treatment, while four patients received afatinib and one patient received erlotinib. The median time to failure of the first EGFR-TKI treatment was 1.6 months. The EGFR-TKIs were switched because of hepatotoxicity (n = 16), interstitial lung disease (n = 3), and other reasons (n = 3). The median washout period was 1.1 months. Seventeen patients received erlotinib as the second EGFR-TKI treatment, while three patients received gefitinib and two patients received afatinib. The median PFS for the second EGFR-TKI treatment was 15.2 months. The median PFS2 was 17.7 months and the median overall survival was 32.8 months.CONCLUSIONS:
Switching EGFR-TKIs because of adverse events provided a clinical benefit for patients with EGFR mutation-positive NSCLC. Appropriate judgment regarding switching from one EGFR-TKI to another may improve the performance status and prognosis of patients with EGFR mutation-positive NSCLC.Palavras-chave
