Abstrakt: Introduction: The use of osimertinib is associated with the risk of cancer therapy-related cardiac dysfunction (CTRCD) for EGFR-mutated non-small cell lung cancer (NSCLC) patients. In this study, we aimed to clarify the clinical features of patients with CTRCD associated with osimertinib.
Methods: A total of 183 cases of advanced EGFR-mutated NSCLC who received osimertinib monotherapy from January 2014 to December 2019 were evaluated. Longitudinal changes in LVEF were evaluated in 58 patients by serial echocardiography before and after osimertinib administration.
Results: Of 58 patients, 16 patients (8.7%) had decreased LVEF of 10 units or more and 8 patients (4.4%) met the CTRCD criteria. Overall, LVEF significantly decreased after osimertinib treatment from a mean value of 69% (range, 52-82%) at baseline to 66% (26-75%) (p < 0.001). During osimertinib treatment, LVEF remained low but did not decline any further. Discontinuation, dose reduction, or switching to another EGFR tyrosine kinase inhibitors resulted in recovery in 6 out of 8 CTRCD patients. Multivariate analysis showed that history of heart disease was a significant predictor of CTRCD (ORR, 4.97; 95% confidence interval [CI], 1.26-19.6; P = 0.022).
Conclusions: Osimertinib was associated with the risk of CTRCD, which is dose-independent and reversible with drug withdrawal.
