Osimertinib induced cardiomyopathy: A case report
Rationale:
Cardiotoxicity related to osimertinib, including cardiac failure, QT prolongation, and atrial fibrillation, has been reported as an extremely rare incidence in patients with advanced non-small cell lung cancer (NSCLC). However, little is known about the occurrence of osimertinib-induced cardiomyopathy.
Patient concerns:
A 76-year old woman was treated with afatinib (40 mg/day) as the 1st line treatment due to recurrence after surgical resection for pulmonary adenocarcinoma. However, she experienced recurrence with positive T790 M, and osimertinib (80 mg/day) was administered as the 2nd line therapy.
Diagnosis:
Four months after osimertinib initiation, she complained of fever and progressive dyspnea, and a diagnostic endomyocardial biopsy confirmed non-specific cardiomyopathy, indicating osimertinib-induced cardiomyopathy.
Interventions and outcomes:
She was treated with furosemide, carvedilol, and enalapril, and her cardiac function, her symptoms, and condition improved 3 weeks after the withdrawal of osimertinib.
Lessons:
Physicians should be alert of the cardiomyopathy-causing potential of osimertinib in advanced NSCLC patients.
