The global status of research in breast cancer liver metastasis: a bibliometric and visualized analysis

Abstract

This study aimed to investigate the distribution laws and research frontiers of international literature, so as to present a holistic bibliometric evaluation of the studies on breast cancer liver metastasis(BCLM). Data were collected from the Web of Science Core Collection database, including publications, year, country, journal, author and keywords. The software VOSviewer and CiteSpace were used for bibliometric coupling, co-authorship, co-citation and co-occurrence analysis. In total, 1,031 publications were analyzed from 2004 to 2020 on BCLM. The year with the highest number of publications was 2006, with 103 papers. The United States, followed by China and Germany were the leading countries on BCLM, accounting for 59% of the whole. The journals that published about BCLM were mainly located in Q1/Q2. Keywords co-occurrence analysis divides BCLM into five clusters:‘basic research’, ‘auxiliary diagnosis and therapy’, ‘liver resection’, ‘clinical trial’ and ‘prognosis’. Main treatment therapies were the latest focus. Burst detection indicated that the trends in BCLM concentrated on subtype and SEER. There is apparently brighter perspective for BCLM research in the coming years, especially in liver resection, subtype and bioinformatics. The consequence of our study as the exclusive scientific evaluation offered an integral overview of BCLM, particularly for research focus and future directions, which can further accurately guide scholars on diagnosis, treatment, and personalized prevention.

Bibliometric Analysis of Global Research on Cancer Photodynamic Therapy: Focus on Nano-Related Research

“…Journal analysis is a common step of bibliometric analysis that could provide important information for researchers to choose the proper journals for submitting their studies. In previous bibliometric studies, journal analysis is usually an essential part ( Ahn and Hwang, 2020 ; Wu et al, 2021a ; Gu et al, 2021 ; Shi et al, 2021 ). Therefore, the characteristics of the most popular journals in this field were analysed.…”

“…Generally, keywords and references analysis are the essence of academic papers, which could reflect the current research focus, help to understand the evolution trend, and predict the research prospect and hotspot in the future ( Gu et al, 2021 ; Shi et al, 2021 ). In this part, we have used two kinds of bibliometric software to allow for comprehensive analysis.…”

“…At present, as a burgeoning method, it has been widely applied on numerous medical fields ( Wu et al, 2021a ; Wu et al, 2021b ). Take the field of oncology as an example, numerous previous studies have analyzed the publication trend and research hotspots of various types of tumors though bibliometric approaches ( Ahn and Hwang, 2020 ; Gu et al, 2021 ; Shi et al, 2021 ). In recent years, along with the development of various interventional techniques for malignant tumors such as chimeric antigen receptor (CAR)-based immunotherapy ( Pouliliou et al, 2020 ; Ou et al, 2022 ), programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors treatment ( Sun et al, 2021 ; Liu et al, 2021 ); molecular targeted therapy ( Sheahan et al, 2018 ), monoclonal antibodies ( Kho and Brouwers, 2012 ), etc .…”

The global status of research in prostate cancer bone metastasis: A bibliometric and visualized analysis

“…It helps researchers find research partners, optimize research topics, and monitor new scientific and technological activities. Shi et al ( 11 ) summarized the main treatment therapies through bibliometric analysis of breast cancer liver metastasis, which was of great significance.…”

“…Recently, Shen et al ( 12 ) collected more than 20 years of literature and published a global bibliometric analysis of artificial intelligence in PCa. In addition, Shi et al ( 11 ) conducted a bibliometric evaluation of liver metastasis in breast cancer. However, no bibliometric articles on PCa bone metastasis have been published.…”
