The Role of Biomarkers to Evaluate Cardiotoxicity

Opinion statementModerate-level evidence suggests that cardiac troponin and natriuretic peptides are useful for risk stratification and early identification of anthracycline cardiotoxicity; however, many of these studies used older chemotherapy regimens, and thus, the applicability to current anthracycline treatment regimens is uncertain. Further research is needed to determine optimal timing and thresholds for troponin and natriuretic peptides in anthracycline-treated patients and evaluate these and other promising biomarkers for anti-HER2 therapies, thoracic radiation, anti-VEGF therapy, and fluoropyrimidine therapy –related cardiotoxicity. Risk tools that combine cardiac risk factors, cancer treatment variables, biomarkers, and imaging parameters are most likely to accurately identify individuals at highest risk for cancer therapy cardiotoxicity. Clinical trials focusing cardioprotective strategies on high-r isk individuals are more likely to result in clinically significant results compared with primary prevention cardioprotective approaches.
