Abstract

A total of 488 articles on ferroptosis in lung cancer were analyzed from 2014 to October 2023.

Publications on ferroptosis in lung cancer have shown significant exponential growth from 2019 to 2023.
The most influential research in this area was published in high-impact journals, with Scott J. Dixon's works being the most cited.
Four primary research themes were identified: Lung Cancer Specifics, Biomarker Identification and Prognosis, Cellular Death Mechanisms and Metabolic Regulation, and Cancer Stem Cells and Therapeutic Resistance.
Recent studies have increasingly focused on the immune microenvironment and mitochondrial dysfunction.
The analysis revealed a global collaborative effort in the field, particularly from researchers in China, the USA, and Germany.

BACKGROUND: Lung cancer, a major cause of cancer-related mortality globally, necessitates innovative therapeutic strategies. Ferroptosis, an iron-dependent, non-apoptotic cell death form, has risen as a crucial therapeutic target. This study aims to conduct a comprehensive bibliometric analysis of ferroptosis in lung cancer, highlighting principal research trends, influential publications, and prospective future directions.

METHODS: This study utilized bibliometric tools such as VOSviewer, CiteSpace, and the R package "bibliometrix" to thoroughly analyze 488 articles on ferroptosis in lung cancer from 2014 to October 2023. Data from the Web of Science Core Collection were analyzed to determine spatial and temporal trends, identify prominent authors and seminal works, and uncover emerging hotspots and frontiers of the field. The literature was segmented into coherent thematic groups through cluster analysis.

RESULTS: Our analysis revealed a significant exponential growth in publications from 2019 to 2023, mirroring the increasing interest in this area. Predominantly, the influential research was published in high-impact journals, with Scott J. Dixon's works being the most cited. The study identified four primary research themes: Lung Cancer Specifics; Biomarker Identification and Prognosis; Cellular Death Mechanisms and Metabolic Regulation; and Cancer Stem Cells and Therapeutic Resistance. Recent studies have increasingly focused on areas such as the immune microenvironment and mitochondrial dysfunction. Furthermore, the analysis highlighted the field's global collaborative nature, with significant contributions from China, the USA, and Germany.

CONCLUSION: This extensive bibliometric analysis emphasizes the growing importance of ferroptosis in lung cancer research. The identified themes and emerging topics underline the field's complexity and suggest new research avenues. This study promotes a holistic research approach, advocating for the exploration of innovative ferroptosis-targeting therapies that could revolutionize lung cancer treatment.
