Maintenance Treatment by Erlotinib and Toxic Cardiomyopathy: A Case Report

Abstract

Erlotinib maintenance treatment improves progression-free survival compared with observation after first-line chemotherapy in unselected advanced non-small cell lung cancer (NSCLC). Very few cardiac adverse effects have been observed in phase III studies on tyrosine kinase inhibitors (TKI). We report the case of a 71-year-old woman with metastatic NSCLC treated with cisplatin/pemetrexed and then erlotinib maintenance therapy. After 26 months of TKI therapy, she developed dilated cardiomyopathy. Despite symptomatic treatment, left ventricular ejection fraction decreased to 25%. Ischemic heart disease was excluded by coronary angiography and cardiac magnetic resonance imaging, and no other cause was found. Erlotinib was stopped, and cardiac resynchronization therapy by pacemaker was initiated. This case report highlights the possible cardiotoxic effects of long-term erlotinib and suggests the need for close clinical and echocardiographic follow-up of patients receiving long-term TKI therapy.

Cardiotoxicity

Cardiotoxicity refers to the muscle damage or dysfunction of heart electrophysiology caused by drug intake or due to disease complications. It is a well-known side effect of several cytotoxic drugs, especially of the anthracyclines and can lead to long term morbidity. Here is the latest research.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
