Abstract
Background: Anthracyclines are highly effective anticancer medication prescribed for the treatment of breast
cancer. Nevertheless, the use of anthracyclines as chemotherapeutic agents involves a risk for development of
cardiac toxicity which may cause restrictive and dilated cardiomyopathy. Currently, genetic predisposition is not
considered as a risk factor for cardiotoxicity associated to the use of anthracyclines.
Case presentation: We report the case of a 37-years old Panamanian female patient diagnosed with breast cancer who
developed clinical signs of severe heart failure after treatment with doxorubicin. A diagnosis of anthracycline induced
cardiomyopathy was made and treatment was initiated accordingly. A whole exome sequencing study performed to the
patient showed the presence of a missense mutation in LMNA gene, which codifies for lamin A/C. Our results points to a
correlation between the LMNA variant and the anthracycline cardiotoxicity developed by the woman. Improvement of
the clinical symptoms and the left ventricle ejection fraction was observed after proper treatment.
Conclusions: This case report suggests for the first time a potential genetic predisposition for anthracyclines induced
cardiomyopathy in patients with mutations in LMNA gene. Perhaps chemotherapies accelerate or deliver the “second-hit”
in the development of DCM in patients with genetic mutations. More data is needed to understand the contribution of
LMNA variants that predispose to DCM in patients receiving cardiotoxic therapies.

Background
Anthracyclines, such as doxorubicin and epirubicin, are
highly effective and frequently used antineoplastic drugs pre-
scribed for a variety of malignancies, including breast cancer
[1, 2]. These drugs inhibit the enzyme topoisomerase II, lead-
ing to disruption in DNA replication and transcription,
which in turn impedes multiplication of cancer cells.
Furthermore, they promote the production of Reactive
Oxygen Species (ROS) which damage proteins, DNA and
cell membranes of the fastest-dividing human cancer cells
[2]. Anthracycline-based chemotherapy for the treatment of
breast cancer is very effective, reducing the annual mortality
in women with breast cancer by 20–38%; nevertheless, the
increased risk of cardiotoxicity in patients from anthracycline
use has been very well described and analyzed in the medical
literature [1–3]. The use of anthracyclines as chemothera-
peutic agents involves an evident risk for development of
cardiac toxicity generating restrictive and dilated cardiomy-
opathy resulting in congestive heart failure in approximately
16–20% of the treated patients [4]. The current assumptions
indicate that anthracycline-induced cardiomyopathy is the
result of complex multifactorial processes affecting cardio-
myocytes such as inhibition of protein and nucleic acid
