Characteristics and research status among clinical trials in cardio‐oncology by bibliometric and visualized analysis

Abstract

AbstractBackgroundWe aim to establish the characteristics of published cardio‐oncology research of clinical trials by bibliometric analysis and to talk about the prospects and difficulties facing the development of cardio‐oncology.MethodsSearch of data related to clinical trials in cardiac oncology from 1990 to 2022 from the Web of Science core collection. Using CiteSpace to perform co‐citation analysis of authors, countries (regions) and institutions, journals and cited journals, cited authors and cited literature, and keywords.ResultsOf the 607 clinical trial studies, the number of papers published per year has increased over time. The regions with the greatest influence were North America (especially the United States) and Europe. Multicenter research has always been the focus of cardio‐oncology research, but cross‐regional cooperation was still lacking. Myocardial toxicity caused by anthracyclines has received the earliest attention and has been studied for the longest time. Meanwhile, the efficacy and cardiotoxicity of new anticancer drugs always came into focus, but at a slow pace. Few studies on myocardial toxicity were related to the treatment of tumors except breast cancer. Risk factors, heart disease, adverse outcomes, follow‐up, and intervention protection were the major hotspots revealed by co‐citation cluster.ConclusionsThere is great potential for the development of clinical trials in cardio‐oncology, especially in multicenter cooperation across different regions. Expansion of tumor types, myocardial toxicity of different drugs, and effective interventions in the research direction and design of clinical trials are necessary.
