Abstract
BACKGROUND
The recent advent of the cyclin-dependent kinase (CDK) 4/6 inhibitors has considerably evolved hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer treatment. Palbociclib, an orally administered pyridopyrimidine derivative, was the first CDK4/6 inhibitor to be introduced into daily clinical practice in combination with classic endocrine backbone, based on progression-free survival (PFS) benefit assessed in the pivotal PALOMA series of randomized clinical trials. Regarding its safety profile, neutropenia and leukopenia are the most common and well-defined adverse effects, while cardiac complications are rather scarce.
CASE REPORT
We present the rare case of a middle-aged female patient with HR+/HER2- metastatic breast cancer, without prior exposure to cardiotoxic antineoplastic agents, who developed Takotsubo cardiomyopathy (TTC) in the context of systemic therapy with palbociclib plus letrozole combination.
CONCLUSIONS
Pharmacovigilance and experimental studies are warranted to confirm any causative relationship and to explore the underlying pathophysiology, respectively.
