This study aimed to analyze and construct a model to assess scientific publications on the relationship between COPD and lung carcinomas.Patients and Methods: A literature search of the Web of Science database was performed for publications until November 2, 2021. Microsoft Excel and CiteSpace software were used to perform bibliometric and visual analysis of source journals, countries/regions, institutions, authors, research areas, and hot topics of selected publications.Results: A total of 2175 publications on the relationship between COPD and lung carcinomas were identified. The annual number of papers published and the total annual citation frequency in the field of COPD and lung carcinoma show an upward trend, and the current research hot topics are health, disease risk factors, disease burden, prevention and serious complications. The top three countries/regions with the number of published articles are the United States, China, and the United Kingdom. The author with the most signatures was Castaldi PJ of USA, followed by Xian JF of China. The lack of multinational/regional multi-center research illustrated that the distribution of research forces is unbalanced.Conclusion: According to this study, researchers can identify hot topics and explore new research directions in research of the relationship between COPD and lung carcinomas.Keywords: lung neoplasms, lung carcinoma, chronic obstructive pulmonary disease, bibliometrics, visualization analysis |
