Diagnosis and management of Cancer therapeutics-related cardiac dysfunction is of crucial importance in breast cancer (BC) patients. The role of advanced echocardiographic techniques, such as deformation imaging, in the diagnosis and characterization of patients receiving cancer therapy has so far involved relatively small studies in the research setting. Therefore, we conducted a meta-analysis and systematic review of observational studies evaluating myocardial changes during chemotherapy detected through conventional echocardiographic parameters, such as 2D left ventricular ejection fraction (2D LVEF), and 2D Speckle tracking echocardiography (STE). The literature search retrieved 487 research works, articles, of which 17 were found to be pertinent with this topic. After full article review, 16 studies were considered suitable for the present analysis. Two separate analyses, one for the anthracyclines-based therapeutic regimen and one for the trastuzumab based therapeutic regimen, were performed. A significant reduction in 2D LVEF and 2D STE parameters during cancer therapy was found in both the investigations. Peak systolic global longitudinal strain demonstrated to be the most consistent 2D STE parameter in detecting early myocardial changes among all the studies. Thus, we confirmed the role of 2D STE for the early detection of myocardial damage, suggesting its crucial role in monitoring BC patients and eventually driving the introduction of cardioprotective treatment.

Abstract

Diagnosis and management of Cancer therapeutics-related cardiac dysfunction is of crucial importance in breast cancer (BC) patients. The role of advanced echocardiographic techniques, such as deformation imaging, in the diagnosis and characterization of patients receiving cancer therapy has so far involved relatively small studies in the research setting. Therefore, we conducted a meta-analysis and systematic review of observational studies evaluating myocardial changes during chemotherapy detected through conventional echocardiographic parameters, such as 2D left ventricular ejection fraction (2D LVEF), and 2D Speckle tracking echocardiography (STE). The literature search retrieved 487 research works, articles, of which 17 were found to be pertinent with this topic. After full article review, 16 studies were considered suitable for the present analysis. Two separate analyses, one for the anthracyclines-based therapeutic regimen and one for the trastuzumab based therapeutic regimen, were performed. A significant reduction in 2D LVEF and 2D STE parameters during cancer therapy was found in both the investigations. Peak systolic global longitudinal strain demonstrated to be the most consistent 2D STE parameter in detecting early myocardial changes among all the studies. Thus, we confirmed the role of 2D STE for the early detection of myocardial damage, suggesting its crucial role in monitoring BC patients and eventually driving the introduction of cardioprotective treatment.
