Myocardial Deformation Imaging by Speckle Tracking Echocardiography for Assessment of Cardiotoxicity in Children During and After Chemotherapy: A Systematic Review and Meta-analysis. J Am Soc Echocardiogr 2022; 35:629-656. [PMID: 35149208 DOI: 10.1016/j.echo.2022.01.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 01/24/2022] [Accepted: 01/26/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND Childhood cancer patients and childhood cancer survivors (CCS) are at risk of developing chemotherapy-induced cardiomyopathy. Myocardial deformation imaging has shown potential in the early detection of subclinical myocardial damage with implications on therapeutic interventions and improvement of outcomes. We aimed to perform a systemic review and meta-analysis of literature on the assessment of left (LV) and right ventricular (RV) myocardial deformation by speckle tracking echocardiography (STE) at rest and during stress in childhood cancer patients during and in survivors after chemotherapy. METHODS A systematic review was performed through searching MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, and Scopus. Search hedges were created to cover the concepts of childhood cancer, chemotherapy, radiotherapy, anthracycline, cardiotoxicity, speckle tracking, myocardial strain, and myocardial deformation. Two independent investigators reviewed the eligibility of the articles for inclusion. Weighted mean difference in ventricular strain between pre-and post-chemotherapy treatment and that between long-term CCS and healthy subjects were estimated by random-effect models with 95% confidence intervals. Heterogeneity and publication bias were assessed by I2 statistics and Egger test, respectively. RESULTS Of the total of 8703 records initially identified, 42 studies with a total of 430 childhood cancer patients were included. Of these 42 studies that showed heterogeneities, 9 assessed early myocardial injury during chemotherapy, 30 assessed late myocardial injury after chemotherapy with no publication bias, and 3 studied myocardial mechanics during stress. The main findings were 1) impairment of LV systolic deformation in childhood cancer patients during the initial treatment phase and among long-term CCS, while data on changes in RV deformation are limited and inconclusive, 2) the predictive value of early reduction of myocardial strain imaging in forecasting subsequent development of cardiotoxicity is unknown as it has not been studied, 3) limited data suggest possibility of impaired LV contractile mechanics during stress in CCS, and 4) cumulative anthracycline dose and chest-directed radiotherapy are consistently identified as factors associated with impaired myocardial deformation.results CONCLUSIONS: Myocardial strain imaging by STE unveils early evidence of myocardial injury in childhood cancer patients and long-term CCS. To support its adoption for clinical use, more data are required for the better understating of myocardial deformation parameters in the risk stratification of childhood cancer patients and prediction of development of cardiomyopathy among CCS.

Circulating high-sensitivity troponin T and microRNAs as markers of myocardial damage during childhood leukaemia treatment. Pediatr Res 2021; 89:1245-1252. [PMID: 32634817 DOI: 10.1038/s41390-020-1049-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Revised: 05/23/2020] [Accepted: 06/23/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND We investigated whether plasma high-sensitivity cardiac troponin T (hs-cTnT) and circulating heart-associated microRNA (miRs) are increased in children with leukaemias during anthracycline-based chemotherapeutic treatment. METHODS In vitro human pluripotent stem cell (hPSC)-derived cardiomyocyte model showed that miR-1, miR-133a, miR-208a, miR-208b, and miR-499 are released from cells into culture medium in a time- and dose-dependent manner on doxorubicin exposure. Left ventricular (LV) myocardial deformation and circulating heart-associated miRs and plasma hs-cTnT during and after completion of chemotherapy were determined in 40 children with newly diagnosed acute leukaemia. RESULTS Significant reduction of LV global longitudinal strain and strain rates were found within 1 week after completion of anthracycline therapy in the induction phase of treatment (all p < 0.05). Hs-cTnT level peaked and miR-1 increased significantly at this time point. Log-transformed hs-cTnT correlated negatively with LV global systolic longitudinal strain (r = -0.38, p < 0.001). Receiver operating characteristic analysis revealed that area under the curve for changes in plasma hs-cTnT from baseline and plasma miR-1 levels in detecting a reduction in ≥20% of global longitudinal strain were respectively 0.62 (95% CI 0.38-0.87) and 0.62 (95% CI 0.40-0.84). CONCLUSION Plasma hs-cTnT and circulating miR-1 may be useful markers of myocardial damage during chemotherapy in children with leukaemias. IMPACT Heart-associated miRNAs including miR-1, miR-133a, miR-208a, miR-208b,and miR-499 were increased in the culture medium upon exposure of hPSC-derived cardiomyocytes to doxorubicin. Only miR-1 increased significantly during anthracycline-based therapy in paediatric leukaemic patients. In paediatric leukaemic patients, plasma hs-cTnT and circulating level of miR-1 showed the most significant increase within 1 week after completion of anthracycline therapy in the induction treatment phase. The study provides the first evidence of progressive increase in circulating miR-1 and plasma hs-cTnT levels during the course of anthracycline-based therapy in children with leukaemias, with hs-cTnT level also associated with changes in LV myocardial deformation.

Abstract
Background: Anthracyclines are widely used to treat childhood cancers; however, they cause cardiotoxicity. To address the paucity of clinical data from Asian populations, this study investigated the epidemiology of pediatric anthracycline-induced cardiotoxicity, during and after chemotherapy, in a multiethnic Asian population. Procedure: This was a single-center, retrospective analysis of 458 anthracycline-treated pediatric oncology patients at KK Women's and Children's Hospital, a tertiary children's hospital in Singapore from 2005 through 2015. We investigated cardiotoxicity (defined as left ventricular fractional shortening <28% on echocardiography) and its risk factors using univariate logistic regression as well as survival estimates through the Kaplan-Meier method to compare survival distribution between patients with and without cardiotoxicity. Results: Over a follow-up period of almost 4 years, we found that 7% (32/458) of the cohort developed cardiotoxicity, with 37.5% (12/32) of these manifesting as clinical heart failure, whilst the rest were asymptomatic. The cardiotoxic cohort demonstrated a significantly higher mortality rate compared to the non-cardiotoxic group at 46.9 vs. 19.2% (p < 0.001), of whom 3 (9.4%) died from end-stage heart failure. We found that traditional predictors such as female sex, age at diagnosis, and cumulative doxorubicin equivalent dose were not predictors of cardiotoxicity. Conclusion: Our study reaffirms that freedom from symptoms does not ensure normal heart function and suggests that children with abnormal ventricular systolic function have higher mortality risk compared to those with normal systolic function. The findings contribute to improved understanding of the Asian burden to aid development of measures to prevent or reduce the risk of cardiotoxicity.

Abstract
PURPOSE Survivorship in children with cancer comes at a cost of developing chronic treatment-related complications. Yet, it is still an under-researched area in Asia, which shares the largest proportion of the global childhood cancer burden given its vast population. This systematic review summarizes existing literature on clinically ascertained health outcomes in Asian survivors of childhood cancer. METHODS A search was conducted on Ovid Medline and EMBASE for studies that focused on survivors of childhood cancer from countries in East and Southeast Asia; adopted post-treatment clinical ascertainment of organ-specific toxicities or/and secondary malignancy. Studies were excluded if health outcomes were assessed during the acute treatment. RESULTS Fifty-nine studies, enrolling a total of 13,442 subjects, were conducted on survivors of leukemia (34%), CNS tumor (14%), and cohorts of survivors with heterogeneous cancer diagnoses (52%). The studies used different medical evaluation methods to assess cardiovascular (15%), metabolic and infertility (32%), and neurological/neurocognitive (20%) outcomes in survivors. The collective findings suggest potential differences in the prevalence of certain late effects (e.g., secondary malignancy and obesity) among Asian and non-Asian populations, which may reflect differences in treatment regimens, practice, genetic variations, or/and socioeconomic disparity. CONCLUSIONS We recommend developing collaborative initiatives to build a regional repository of systematically assessed health outcomes and biospecimens to investigate treatment, social-environmental and genetic predictors, and interventions for late effects in this population. IMPLICATIONS FOR CANCER SURVIVORS The existing types of chronic health problems identified in this review suggest the need for active screening, better access to survivorship care, and promotion of protective health behavior in Asia.

Abstract
OBJECTIVE Anthracyclines are widely used to treat solid and hematologic malignancies, but are known to cause cardiotoxicity. As more childhood cancer survivors reach adulthood due to improvements in oncologic treatments, they become susceptible to late and progressive anthracycline-induced cardiotoxicity. Nonetheless, diagnostic criteria for early detection of cardiac dysfunction are not well defined in children, adolescent, and young adults (CAYA, ages 1-40 years). We present a natural history of the changes in myocardial deformation in CAYA patients after anthracycline therapy. METHODS We performed a literature review search between 2001 and 2016 using PubMed with the following search terms: strain (or deformation), torsion (or twist), children (or adolescent or young adult), cardiotoxicity (or dysfunction), and anthracyclines (or doxorubicin). A total of 23 articles were reviewed. Fourteen articles were incorporated in the meta-analysis. RESULTS Strain abnormalities are observed at both short-term and long-term follow-up. Global longitudinal strain (GLS) abnormalities are common during or early after chemotherapy, whereas changes in global circumferential strain (GCS) are more significant and consistent on long-term follow-up. Although global radial strain and torsional parameters are also often abnormal late after chemotherapy, there are few studies evaluating these parameters. CONCLUSION There are significant abnormalities in GLS and GCS following anthracycline therapy acutely and late after treatment. The prognostic value of these strain abnormalities warrants further investigation.

Abstract
This article provides an overview of studies addressing effects of ionizing radiation on the heart. Clinical studies have identified early and late manifestations of radiation-induced heart disease, a side effect of radiation therapy to tumors in the chest when all or part of the heart is situated in the radiation field. Studies in preclinical animal models have contributed to our understanding of the mechanisms by which radiation may injure the heart. More recent observations in human subjects suggest that ionizing radiation may have cardiovascular effects at lower doses than was previously thought. This has led to examinations of low-dose photons and low-dose charged particle irradiation in animal models. Lastly, studies have started to identify non-invasive methods for detection of cardiac radiation injury and interventions that may prevent or mitigate these adverse effects. Altogether, this ongoing research should increase our knowledge of biological mechanisms of cardiovascular radiation injury, identify non-invasive biomarkers for early detection, and potential interventions that may prevent or mitigate these adverse effects.

Acta Paediatr 2015; 104:313-9. [PMID: 25393922 DOI: 10.1111/apa.12862] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Revised: 10/26/2014] [Accepted: 11/10/2014] [Indexed: 11/26/2022]
Abstract
AIM The role that plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponins T (cTnT) and I (cTnI) play in supplementing imaging to screen for cardiac late effects remains controversial and the impact of high-sensitivity cTnT and troponin-specific autoantibodies (cTnAAbs) remains unexplored. We studied the role of cardiac biomarkers as indicators of the late effects of anthracyclines among childhood cancer survivors. METHODS We measured NT-proBNP, cTnT, high-sensitivity cTnT, cTnI and cTnAAbs in 76 childhood cancer survivors at a median of 9 years after primary diagnosis. The survivors underwent conventional and real-time three-dimensional echocardiography and 62 underwent cardiac magnetic resonance imaging (MRI). RESULTS Of the survivors, four (5.3%) without risk factors for cardiotoxicity were cTnAAb-positive with an impaired cardiac function in MRI. Another four (5.3%) had an abnormal NT-proBNP level associated with an abnormal cardiac function and risk factors for cardiotoxicity. None showed measurable cardiac troponins, determined by the three different methods, with even the high-sensitivity cTnT-levels remaining normal. CONCLUSION Elevated plasma NT-proBNP or cTnAAbs indicated that childhood cancer survivors benefitted from being evaluated with modern imaging, despite normal function in conventional echocardiography. However, troponins did not seem to provide additional information on the late cardiotoxicity of anthracyclines.
