OBJECTIVE: New chemotherapy and immunotherapy agents have revolutionized cancer treatment, significantly improving patient survival rates and quality of life while extending lifespans. However, these therapies often come with severe side effects, particularly cardiotoxicity. Over the past few decades, this field has seen steady growth. To better understand current trends, research hotspots, and collaborative networks in this area, a bibliometric analysis of relevant literature was conducted. METHODS: A comprehensive search was performed in the Web of Science for articles on cardiotoxicity induced by chemotherapy and immunotherapy in cancer treatment, published in SSCI and SCI-EXPANDED up to October 21, 2024. Using software tools such as GraphPad Prism, CiteSpace, and VOSviewer, we analyzed various parameters including publication year, countries, institutions, journals, authors, and references. Additionally, co-occurrence analyses, cooperation relationship assessments, co-citation networks, keyword maps, clustering analyses, and keyword emergence evaluations were conducted. RESULTS: As of October 21, 2024, a total of 5290 articles from 5674 institutions and 27,528 authors across 114 countries and regions were collected. The annual publication frequency and rate steadily increased. The United States emerge as the leading country in terms of publication volume, with the University of Texas System being the most prolific and frequently cited institution. "Breast Cancer Research and Treatment" was among the journals with revelant publications. Notable contributors included Ky bonnie and Thavendiranathan Paaladinesh, while Cardinale D achieved the highest average citation count per publication. Current research hotspots included echocardiography, trastuzumab, doxorubicin, radiotherapy, myocarditis, and 5-fluorouracil. The trend suggests that cardiotoxicity is expected to play an increasingly critical role in chemotherapy and immunotherapy for cancer treatment. CONCLUSION: This study provides a bibliometric visualization analysis of cardiotoxicity induced by chemotherapy and immunotherapy in the cancer treatment. It highlights current developments, collaborative efforts, and research hotspots within this field, offering essential scientific reference value for Cardio-Oncology.
