The successful treatment of cancer has seen significant advancements in recent years, with a growing emphasis on precision medicine. However, some cancer treatments, particularly certain chemotherapeutic agents and targeted therapies, can be associated with cardiotoxic side effects that may compromise the cardiovascular health of cancer patients. In response to this challenge, cardioprotective therapies are being developed and integrated into cancer care [1]. This article explores the importance of biomarkers in identifying and monitoring cardiotoxicity in cancer patients and evaluates the role of these biomarkers in guiding the use of cardioprotective therapies.
The intersection of cancer treatment and cardiotoxicity
Cardiotoxicity refers to the adverse effects of cancer treatments on the heart and cardiovascular system. It can manifest as various cardiovascular conditions, including heart failure, arrhythmias and ischemic heart disease. Several cancer therapies, such as anthracyclines, tyrosine kinase inhibitors and immune checkpoint inhibitors, have been associated with cardiotoxicity [2]. Understanding the risk factors and monitoring mechanisms is crucial to prevent and manage these side effects.
The role of cardioprotective therapies
Cardioprotective therapies aim to mitigate the cardiotoxic effects of cancer treatments. These interventions can include medications like beta-blockers and angiotensin-converting enzyme (ACE) inhibitors, lifestyle modifications and the use of liposomal formulations of chemotherapy drugs. Cardioprotective therapies are used both for the prevention of cardiotoxicity in patients at risk and for the management of cardiotoxicity when it occurs [3]. Identifying individuals who are at a higher risk of cardiotoxicity is crucial for early intervention.
The need for biomarkers
Biomarkers are measurable indicators that can provide insights into a patient's health or the effects of a specific treatment. In the context of cancer treatment, biomarkers can serve as predictive tools, identifying individuals at a higher risk of cardiotoxicity. Biomarkers are also valuable for monitoring the progression of cardiotoxicity during cancer treatment. Changes in biomarker levels can signal the development of cardiac issues and prompt timely intervention.
Prominent cardiotoxicity biomarkers
Cardiac troponins, particularly troponin I and troponin T, are wellestablished biomarkers for myocardial damage. Elevated levels of cardiac troponins can indicate myocardial injury and are associated with cardiotoxicity. Natriuretic peptides, such as brain natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), are released in response to cardiac stress or strain. These biomarkers can help identify early signs of heart failure. Advanced cardiac imaging techniques, such as echocardiography, magnetic resonance imaging (MRI) and nuclear imaging, can provide imaging biomarkers to assess cardiac function and detect structural abnormalities [4]. Inflammatory biomarkers, such as C-reactive protein (CRP) and interleukin-6 (IL-6), may play a role in identifying inflammation-induced cardiotoxicity, which can occur with certain immunotherapies.
The clinical utility of biomarkers
Biomarkers can stratify patients into risk categories, allowing oncologists and cardiologists to tailor their treatment plans. Patients at higher risk may benefit from early intervention with cardioprotective therapies. Biomarkers can also track a patient's response to cardioprotective therapies. Improvements or worsening of biomarker levels can indicate the effectiveness of the intervention [5]. The integration of biomarkers in cancer care enables a more personalized approach, where the risk of cardiotoxicity is assessed for each patient and treatment strategies are adjusted accordingly.
Challenges and future directions
The standardization of biomarker testing and interpretation is crucial to ensure consistent results across different healthcare settings and laboratories. Ongoing research aims to identify new and more specific biomarkers for cardiotoxicity, enhancing our ability to predict and monitor these side effects. Combining multiple biomarkers and imaging techniques can provide a more comprehensive assessment of cardiotoxicity and its management.
The intersection of cancer treatment and cardiotoxicity highlights the significance of identifying and managing the cardiovascular side effects of cancer therapies. Biomarkers play a vital role in this process, serving as tools for risk assessment, early detection and personalized intervention. The integration of cardioprotective therapies with biomarker-guided care represents a significant advancement in cancer treatment, ultimately aiming to improve patient outcomes and enhance the overall quality of cancer care. As research continues to evolve, the clinical utility of biomarkers in the context of cardiotoxicity is expected to expand, leading to more effective and tailored approaches to cancer treatment.
