Introduction: Cabozantinib is a multikinase inhibitor agent used in the treatment of hepatocellular, renal, and thyroid cancers. The development of heart failure after cabozantinib initiation is an extremely rare side effect, with only four case reports published in the literature. We describe a case of cabozantinib-induced cardiac failure in a patient with thyroid cancer refractory to standard treatment., Case Report: Fifty-seven-year-old woman had no history of cardiovascular disease. Echocardiography prior to chemotherapy revealed normal cardiac function. However, she developed pretibial edema and shortness of breath after 2 months of cabozantinib treatment. Ejection fraction was found to be 30% in the echocardiography of the patient, and global hypokinesia was detected in cardiac functions., Management and Outcome: Cabozantinib treatment of the patient was discontinued. After discontinuation of treatment, the patient's cardiac functions did not return to normal. Heart failure due to cabozantinib treatment was thought to be permanent., Discussion: There are only four cases on this subject in the literature. Although the use of cabozantinib rarely causes heart failure, this side effect can have extremely serious consequences. Even if it is a rare condition, cardiological evaluations should be performed before and after cabozantinib therapy because it can be reversible after discontinuation of the treatment., Competing Interests: Author contributionsThe authors listed below have contributed to study as stated in the list.SS contributed to the conception, revising, final approval of the version to be published, and agreed to be accountable for all aspects of the work.
