Protective Role of Enalapril in Anthracycline-Induced Cardiotoxicity: A Systematic Review

Current Status and Trends of Research on Anthracycline-Induced Cardiotoxicity from 2002 to 2021: A Twenty-Year Bibliometric and Visualization Analysis

Anthracyclines constitute the cornerstone of numerous chemotherapy regimens for various cancers. However, the clinical application of anthracyclines is significantly limited to their dose-dependent cardiotoxicity. A comprehensive understanding of the current status of anthracycline-induced cardiotoxicity is necessary for in-depth research and optimal clinical protocols. Bibliometric analysis is widely applied in depicting development trends and tracking frontiers of a specific field. The present study is aimed at revealing the status and trends of anthracycline-induced cardiotoxicity during the past two decades by employing bibliometric software including R-bibliometric, VOSviewer, and CiteSpace. A total of 3504 publications concerning anthracycline-induced cardiotoxicity from 2002 to 2021 were collected from the Web of Science Core Collection database. Results showed significant growth in annual yields from 90 records in 2002 to 304 papers in 2021. The United States was the most productive country with the strongest collaboration worldwide in the field. Charles University in the Czech Republic was the institution that contributed the most papers, while 7 of the top 10 productive institutions were from the United States. The United States Department of Health and Human Services and the National Institutes of Health are the two agencies that provide financial support for more than 50% of sponsored publications. The research categories of included publications mainly belong to Oncology and Cardiac Cardiovascular Systems. The Journal of Clinical Oncology had a comprehensive impact on this research field with the highest IF value and many publications. Simunek Tomas from Charles University contributed the most publications, while Lipshultz Steven E. from the State University of New York possessed the highest H-index. In addition, the future research frontiers of anthracycline-induced cardiotoxicity might include early detection, pharmacogenomics, molecular mechanism, and cardiooncology. The present bibliometric analysis may provide a valuable reference for researchers and practitioners in future research directions.

Prevention of anthracycline-induced cardiotoxicity: a systematic review and network meta-analysis

Background Anthracycline based chemotherapy is commonly used in many malignancies. While life expectancy increases with the use of this medication, cardiac toxicity causes a risk for patients' health due to anthracyclines. Objective This systematic review and meta-analysis emphasizes on prevention of anthracycline-associated cardiotoxicity in breast cancer and lymphoma patients. Methods We conducted a systematic review of electronic databases including PubMed, Medline, EMBASE, ClinicalTrials.gov, Web of Science, and the Cochrane Library from inception to June 2019 collecting published articles on primary prevention of anthracycline-associated cardiotoxicity in breast cancer and lymphoma patients. We conducted a network meta-analysis and a pairwise meta-analysis in order to compare direct and indirect cardiac agents group with control group calculate left ventricular ejection fraction change. Primary studies results were pooled using random effects model, frequent network meta-analyses, and performed pairwise meta-analysis using netmeta and meta packages respectively in R software version 3.5.1. Results Twelve studies reported left ventricular ejection fraction outcome among 526 patients in the cardiac agent group and 508 in the control group. Based on Surface Under the Cumulative Ranking cure result, spironolactone was the best in left ventricular ejection fraction change and based on meta-analysis, cardiac group had 1.98 unit left ventricular ejection fraction more than the control group (MD = 1.98, 95% CI 0.15-3.81, p value = 0.03). Conclusions The amount of left ventricular ejection fraction used by cardiac agents in anthracycline-based chemotherapy was reduced to a lesser extent. The effective and ineffective drugs were spironolactone and metoprolol, respectively.
