Bibliometric and visual analysis of photodynamic therapy for lung cancer from 2010 to 2022.

Abstract

A growing body of research shows that photodynamic therapy (PDT) has become an important mode of treatment in the field of lung cancer (LC) in recent years. Although numerous papers related to PDT in LC have been published, no bibliometric studies have been conducted to summarize the research prospects and highlight the research trends and hotspots in this field. This bibliometric analysis was conducted to investigate and provide a systematic understanding of the development of PDT research for LC over the past 13 years with the aim of providing a reference for new directions and strategies in the field of PDT for LC. In May 2023, relevant publications from the Web of Science Core Collection were downloaded, and CiteSpace and VOSviewer were used to conduct the scientometrics analysis in this study.Results: A total of 2,932 articles and reviews that met the inclusion criteria were retrieved, with China dominated the volume of publications from 2010 to 2022 and the most prolific institution was Shanghai Jiao Tong University. PDT can be utilized for the diagnosis and treat LC. Bronchoscopic fluorescence diagnosis using photosensitizers helps to detect tumor changes in the large bronchial mucosa. In the future, we should actively explore the use of new photosensitizers, including the development of nanomaterials, in addition, PDT combined with other treatments can significantly prolong survival. This combination therapy may also be the direction of future research.
