Global hotspots and future prospects of chimeric antigen receptor T-cell therapy in cancer research: a bibliometric analysis

Abstract

Aim: Our study aimed to analyze the characteristics of papers published on CAR T-cell in the field of cancer and explore the existing hot topics and prospects. Materials & methods: We explored the global hotspots and future prospects regarding CAR T-cell therapy in cancer research. Papers of CAR T-cell research were retrieved from the Web of Science database. Analysis was performed using VOSviewer, CiteSpace and Excel software. Results: A total number of 1994 papers related to CAR T-cell research of cancer were included. Molecular Therapy published the most papers (n = 85, 4.26%). A total of 9792 authors participated in the publication of all papers. 62 countries and 2065 institutions have participated in the publication of all papers. Conclusion: Research trends are to improve the immunosuppressive microenvironment of cancer, optimize the structure of CAR T-cells and develop ‘super CAR T-cell’ by using gene-editing technology.
