Research Hotspots of Interferon Gamma in the Treatment of Lung Cancer: A Bibliometric Analysis Based on CiteSpace.

Interferon-gamma (IFN-γ) is an important cytokine associated with antitumor immunity and has been implicated in the pathogenesis and progression of lung cancer. Nevertheless, no bibliometric analyses have been published in this field to date, and thus we aim to address this gap in knowledge. A search of the Web of Science (WOS) for literature related to the treatment of lung cancer with IFN-γ was conducted from 2002 to 2024. The extracted information from the included articles was subjected to visual analysis, and network diagrams were generated using software such as CiteSpace and VOSviewer. In total, 589 articles related to the treatment of lung cancer with IFN-γ were included in WOS between 2002 and 2024. The number of articles and citation frequency generally showed an increasing trend year by year. The United States and the University of California are the countries and institutions with the largest number of articles. The researcher who made the largest contribution to this field was Xin Cai from China (6). The published the largest number of relevant papers in the field (16 papers, IF = 12.469). The research hotspots in the field of immune escape in recent years have been IFN-γ, mechanism, immune checkpoints, and microtumor inhibitors. The field of IFN-γ treatment of lung cancer is evolving at a rapid pace. The current research focus within this field is on elucidating the mechanism of IFN-γ treatment of lung cancer, investigating the role of immune checkpoint inhibitors, and examining the tumor microenvironment and other pertinent topics.
