Studies related to osteosarcoma and metabolism from 1990 to 2022: A visual analysis and bibliometric study

Background: Osteosarcoma is the most common primary bone tumor, its high incidence of metastasis and poor prognosis have led to a great deal of concern for osteosarcoma. In many cancer types, metabolic processes are important for tumor growth progression, so interfering with the metabolic processes of osteosarcoma may be a therapeutic option to stall osteosarcoma progression. A key mechanism of how metabolic processes contribute to the growth and survival of various cancers, including osteosarcoma, is their ability to support tumor cell metabolism. Research related to this field is a direction of great importance and potential. However, to our knowledge, no bibliometric studies related to this field have been published, and we will fill this research gap.

Methods: Publications were retrieved on January 1, 2023 from the 1990-2022 Science Citation Index of the Web of Science Core Collection. The Bibliometrix package in R software, VOSviewer and CiteSpace software were used to analyze our research directions and to visualize global trends and hotspots in osteosarcoma and metabolism related research.

Results: Based on the search strategy, 833 articles were finally filtered. In this area of research related to osteosarcoma metabolism, we found that China, the United States and Japan are the top 3 countries in terms of number of articles published, and the journals and institutions that have published the most research in this area are Journal of bone and mineral research, Shanghai Jiao Tong University. In addition, Baldini, Nicola, Reddy, Gs and Avnet, Sofia are the top three authors in terms of number of articles published in studies related to this field. The most popular keywords related to the field in the last 30 years are “metabolism” and “expression”, which will guide the possible future directions of the field.

Conclusion: We used Bibliometrix, VOSviewer, and Citespace to visualize and bibliometrically analyze the current status and possible future hotspots of research in the field of osteosarcoma metabolism. Possible future hotspots in this field may focus on the related terms “metabolism”, “expression”, and “migraation”.

Introduction

Abnormal metabolism is the main feature of cancer. Abnormal cancer metabolism, changes in the anabolic pathways of certain substances such as lipid metabolism, glutamine metabolism and glucose metabolism plays a crucial role in tumorigenesis, development and metastasis (1–6).The abnormal metabolism of cancer cells is the result of genetic mutations, and more importantly, it can also directly affect the signaling of tumor cells and the responses made by the final cells (7). In recent years there has been an increasing interest in the field of cancer metabolism in many basic experiments and clinical trials. Researchers are aiming to determine whether cancer development or progression can be halted by curbing the metabolic changes in cancer. Metabolism is also important in the development, progression and metastasis of osteosarcoma.

Osteosarcoma (OS) is the most common malignant bone tumor, occurring in children and adolescents, with an incidence of less than 5 per million (8, 9). Although treatment for OS includes a variety of treatments, including surgical resection and chemotherapy, overall survival remains poor (10). One of the main reasons for the poor prognosis is that the metabolic process of osteosarcoma is not well understood, and the development, progression, or metastasis of osteosarcoma is not well prevented. development or metastasis.

Bibliometrics is an emerging approach in recent years to provide an in-depth scientific qualitative and quantitative analysis and visualization of the published literature in a specific research area, which can provide a better and clearer understanding of the current status and future trends of a research area (11, 12).Unlike previous traditional systematic assessments, bibliometric analyses focus on author collaboration networks and national regions of the literature, and on the interconnectedness of different research institutions and individual journals publishing in the field (13).To the best of our knowledge, there are no bibliometric studies on the metabolism-related aspects of osteosarcoma research to date. Bibliometrics has been used in several disciplines, such as digestive (14), neurological (15), and cancer systems (16). Therefore, the purpose of this study was to provide an in-depth analysis and visualization of research on osteosarcoma metabolism from 1990 to 2022, as well as to assess the current state of research and future trends and hot spots in this area of osteosarcoma metabolism.

Methods and materials

Data collection and retrieval process

We searched the Web of Science (WoS) systematically for the period from January 1, 1990 to December 20, 2022. The WoS contains a huge number of journal categories and is the most frequently read database (17).Compared to other databases, the WoS database is more comprehensive, clearer, and broader (18),and is the most suitable database for bibliometric research (19–21).We also downloaded the data on January 1, 2023. Search terms included: TS = (osteosarcoma) and TS = (metabolism). After careful and multiple screening, only theses and review articles were retained, we removed literature that was not relevant to our study topic and restricted the language type to English only, extracted and saved in txt format, where these files were plain text files with full records and cited references retained for better visualization and bibliometric analysis of our study. Figure 1 can better demonstrate our process of screening the literature.

Presentation of the software and its tools for visualization and bibliometrics to be used in this study

VOSviewer (22)and CiteSpace (23) can display the collaborative network relationships and keywords between different authors, countries, and institutions of the published literature in a certain research area. In the results presented by the CiteSpace software, each point in the graph represents an element, which can be an author, a country, an institution or a keyword. The lines between the points represent the strength of their relevance or the frequency of collaboration and relationships (23, 24). The sets of elements in different kinds of colors indicate different clusters (25).

In addition, R language software (26) is required, of which the Bibliometrix R package provides a quantitative tool for bibliometric analysis studies.

Discussion

We have done considerable research analysis work to deeply analyze and visualize the authors, country regions, and journals of articles published in the field of research related to osteosarcoma metabolism between January 1, 1990 and December 20, 2022. Based on this, we tried to show the current status of research in this field and possible future hotspots and trends, contributing to the development of the field and further value creation. We used Citespace, VOSviewer and other software to make a visual analysis of the last 30 years of research in this field, we found that there are 833 articles in this field, of which 5 of the top 10 published institutions are Chinese universities, but the most cited institution is the University of Bologna. China is the most cited country in the field, while the United States is the most cited overall and Canada is the number one cited on average.

In terms of authors, we found that in addition to the previously described, Baldini, nicola also studied the relationship between osteosarcoma cell secretion and metabolism and nanoparticles (31) and also Hall, ih mainly studied some elements of multiple drugs in the field of osteosarcoma metabolism studies, such as in vitro studies of osteosarcoma cells (32) and anti-tumor studies of compounds (33–35).

From the results of our analysis, China and the United States are the absolute centers of research in the field of osteosarcoma metabolism, with 470 publications from these two countries, accounting for about half of the global number of publications in this field.

The keywords found in the results are “metabolism”, “expression”, “cancer”, “osteosarcoma”, and “growth”. and “growth” are the words that appear very frequently. These words also indicate roughly the hottest research directions in the field between 1990 and 2022.

In addition, we analyzed the outbreak terms that have emerged in the field over the past 30 years, a method unique to Citespace software. It is a term that mainly reflects whether there are significant changes in a research field during a specific period of time, and can indicate hot spots and future trends for researchers. In the field of osteosarcoma metabolism research, we found that the main outbreak words in recent years are “cancer cell”, “mesenchymal stem cell”, “ migration”, “cancer”, and “signaling pathway”, which will mostly emerge and explode in 2017-2022. This can also predict that the research field in osteosarcoma metabolism may revolve around these hot spots in the coming years.

Our study is the first bibliometric analysis and visualization of this research area of osteosarcoma metabolism. Of course, our bibliometric’s have limitations inherent to this type of study. It is difficult to achieve simultaneous use of multiple databases in a bibliometric study, so we used only the WoS database, but considering that the WoS database is the most widely used, recognized, and covered database in bibliometrics (36, 37), the results generated reflect the overall trend.

Conclusion

We conducted a bibliometric study and visualization of research in the field of osteosarcoma metabolism from 1990 to 2022 using several software such as VOSviewer and Citespace. From the results of our presentation, it is clear that metabolic research in the field of osteosarcoma is slowly becoming a hot direction in the field of osteosarcoma research with good prospects. baldini, nicola, Reddy, Gs, and Avnet, Sofia are the three authors with the highest number of publications in this field. China, USA and Japan are the three countries with the highest number of publications in this field. Shanghai Jiao Tong University, University of Bologna and Zhejiang University are the top 3 academic institutions in terms of number of publications. mesenchymal stem cell”, “migration”, “cancer”, and “signaling pathway” are the potential research hotspots in this field in recent years and in the future. This study is the first review of nearly three decades of research on relevant aspects of osteosarcoma metabolism through bibliometric analysis and provides a reference for future research.
