ABSTRACT
As the number of cancer survivors has increased significantly over the last decades due to aging of population and development of effective cancer therapies, side effects from cancer therapies have been increasingly recognized. High-dose anthracyclines, immunotherapies, and concurrent radiation, as well as traditional cardiovascular risk factors such as smoking, hypertension, diabetes, hyperlipidemia, and obesity increase risks for unintended cardiovascular toxicity. However, these factors do not fully explain why only a subset of patients develop adverse cardiovascular sequelae from cancer therapies. Recent studies demonstrate that genetics play a substantial role in susceptibility to development of cardiovascular toxicities from cancer therapies. Common single nucleotide polymorphisms in multiple genes involved in various cellular pathways including membrane transport, stress response, and sarcomeres are recognized to increase risks for these toxicities. Pathogenic variants in the genes encoding proteins that comprise sarcomeres also contribute to cardiomyopathy following cancer therapies. Furthermore, genetic manipulations of model systems indicate mechanisms by which cardiotoxicities emerge following cancer immunomodulatory therapies. Continued efforts are needed to enable insights into cardiovascular responsiveness to these multi-targeted therapies, improve risk stratification of patients, and enable therapeutic interventions that limit these unintended adverse consequences from life-saving cancer treatments.
