Background: Although bispecific antibodies (BsAbs) hold promising therapeutic prospects in solid tumors, there is scarce bibliometric analysis on this field. This study aimed to systematically map the research landscape, identify key trends, and highlight future directions for BsAb research in solid tumors. Methods: Literature of BsAb development for solid tumors was retrieved from Web of Science Core Collection published between 2006 and 2025. Publication distribution, research trends and hotspots were analyzed and visualized by VOSviewer, CiteSpace and the R package “bibliometrix”. Results: Overall, we identified 3632 publications stemming from a fast-growing field currently strongly influenced by the United States and China, with Memorial Sloan Kettering Cancer Center and National Cancer Institute the most productive research centers, Front Immunol the most productive journal and J Clin Oncol the most cited. The dominant research topics that appeared from keyword analysis are bispecific antibody, immunotherapy, targeted therapy, non-small cell lung cancer, and EGFR. Conclusion: This study documents the evolution of BsAb research, from basic science to clinical translational research in solid tumors. The research in this field is highly mature at this point, with emphasis on the targeting of specific tumor types and specific antigens. In order to further push forward the frontier, greater international and subfield collaborations, as well as larger-scale clinical trials targeting broader indications, overcoming resistant mechanisms and combination strategies are necessary.
