Key result

Cardiac troponin detects early cancer therapy cardiotoxicity effectively, though differential diagnosis remains challenging.

Figures

Why the study?

Troponin levels can increase across numerous scenarios in cardio-oncology, making differential diagnosis challenging despite its clinical value as a biomarker of myocardial damage.

Key Points

To review the pathological conditions, cellular mechanisms, and clinical utility of elevated cardiac troponin levels in patients with malignancies.
Literature review analyzing molecular and cellular mechanisms of cardiac troponin release, differences between troponin T and troponin I isoforms, and clinical guidelines in cardio-oncology.
Cardiac troponin release reflects both cancer therapy-associated cardiotoxicity and direct tumor effects, with unbound cytosolic reserves (approximately 5% for cTnI and 8% for cTnT) mediating rapid early release after cardiomyocyte membrane injury.
Troponin T and troponin I exhibit distinct kinetics and diagnostic limitations, as cTnT clearance depends on renal function and can be elevated during skeletal muscle injury or immune checkpoint inhibitor-induced myositis without myocardial involvement.

Structured PICO

P

Population

Patients with malignancies, particularly those undergoing potentially cardiotoxic oncological therapies.

Understanding the diverse cellular and molecular mechanisms of troponin release is crucial for optimizing cardio-oncological care and interpreting biomarker elevations in cancer patients.

Limitations

Lack of consensus regarding optimal cut-off values, specificity, and sensitivity of troponin in cancer patients.
Limited evidence comparing the performance of cTnT and cTnI in cardiotoxicity.
Potential for false-positive elevations due to skeletal muscle disease, analytical cross-reactivity, or macrotroponin.
Lack of consensus regarding optimal cut-off values, specificity, and sensitivity of troponin in cancer patients
Troponin's role in oncology is not yet fully established despite 30 years of diagnostic use
Scarce literature on the significance of macrotroponin confounding differential diagnosis in this cohort

Implication

Troponin monitoring may inform cardiotoxicity surveillance in oncology; leaves open standardization of assays and thresholds across therapies.

Abstract

Recent advances in oncological therapies have significantly improved cancer survival rates. However, these therapies have also led to an increased risk of cardiovascular alterations. Cardiac troponin, which is well-known for its role in diagnosing myocardial damage, is gaining recognition as a biomarker in the field of cardio-oncology. Despite its clinical value, differential diagnosis remains challenging, as troponin levels can increase in numerous scenarios, particularly in cardio-oncology. While the most recognized cause is the cardiotoxicity associated with cancer therapy, malignant tumors may also directly impact the myocardium. Furthermore, different cardiac troponins, such as troponins T and I, may have distinct biomarker roles, adding to diagnostic complexity. This review aims to summarize the pathological conditions that cause elevated serum cardiac troponin levels in patients with malignancies. We explore the underlying mechanisms at the molecular and cellular levels and discuss potential clinical applications. We also highlight existing gaps in the current evidence and outline future research directions in this rapidly evolving field.
