Advances and key focus areas in gastric cancer immunotherapy:A comprehensive scientometric and clinical trial review(1999-2023)

BACKGROUND Gastric cancer(GC)is the sixth most common cancer and third leading cause of cancer-related deaths worldwide.Current treatments mainly rely on surgery-and chemotherapy-based systemic;however,the prognosis remains poor for advanced disease.Recent studies have suggested that immunotherapy has significant potential in cancer therapy;thus,GC immunotherapy may improve quality of life and survival for patients with this disease.AIM To provide a comprehensive overview of the knowledge structure and research hotspots of GC immunotherapy.METHODS We conducted a bibliometric analysis of publications on immunotherapy related to GC in the Web of Science Core Collection database.We analyzed 2013 publications from 1999 to February 1,2023,using the VOSviewer and CiteSpace software.We assessed publication and citation distributions using the WoS platform and explored research countries,institutions,journals,authors,references,and keywords(co-occurrence,timeline view,and burst analysis).In addition,we examined 228 trials on immunotherapy,137 on adoptive cell therapy,274 on immune checkpoint inhibitors(ICIs),and 23 on vaccines from ClinicalTrials.gov and the International Clinical Trials Registry Platform.The Impact Index Per Article for the top ten high-cited papers collected from Reference Citation Analysis(RCA)are presented.RESULTS Our bibliometric analysis revealed that the study of immunotherapy in GC has developed rapidly in recent years.China accounted for almost half the publications,followed by the United States.The number of publications in recent years has been growing continuously,and most institutions and authors with the most publications are from China.The main keywords or clusters identified were“tumor microenvironment”,“adoptive immunotherapy”,“dendritic therapy”,and“microsatellite instability”.CONCLUSION Our analysis of 2013 publications indicated that immunotherapy for GC has led to several new developments in recent years.Considerable progress has been made in vaccinations,immune checkpoint therapy,and adoptive cellular therapy.In particular,ICIs and chimeric antigen receptor T-cells are novel options for the treatment of GC.We suggest that the combination of ICIs,chemotherapy,targeted therapy,and other immunotherapies should be the primary research direction in the future.

A Scientometric Study of Digital Literacy,ICT Literacy,Information Literacy,and Media Literacy

Purpose:Digital literacy and related fields have received interests from scholars and practitioners for more than 20 years;nonetheless,academic communities need to systematically review how the fields have developed.This study aims to investigate the research trends of digital literacy and related concepts since the year of 2000,especially in education.Design/methodology/approach:The current study analyzes keywords,co-authorship,and cited publications in digital literacy through the scientometric method.The journal articles have been retrieved from the WoS(Web of Science)using four keywords:"Digital literacy,""ICT literacy,""information literacy,"and"media literacy."Further,keywords,publications,and co-authorship are examined and further classified into clusters for more in-depth investigation.Findings:Digital literacy is a multidisciplinary field that widely embraces literacy,ICT,the Internet,computer skill proficiency,science,nursing,health,and language education.The participants,or study subjects,in digital literacy research range from primary students to professionals,and the co-authorship clusters are distinctive by countries in America and Europe.Research limitations:This paper analyzes one fixed chunk of a dataset obtained by searching for all four keywords at once.Further studies will retrieve the data from diverse disciplines and will trace the change of the leading research themes by time spans.Practical implications:To shed light on the findings,using customized digital literacy curriculums and technology is critical for learners at different ages to nurture digital literacy according to their learning aims.They need to cultivate their understanding of the social impact of exploiting technology and computational thinking.To increase the originality of digital literacy-related studies,researchers from different countries and cultures may collaborate to investigate a broader range of digital literacy environments.Originality/value:The present study reviews research trends in digital literacy and related areas by performing a scientometric study to analyze multidimensional aspects in the fields,including keywords,journal titles,co-authorship,and cited publications.

Infrastructure of Scientometrics: The Big and Network Picture

A network is a set of nodes connected via edges,with possibly directions and weights on the edges.Sometimes,in a multi-layer network,the nodes can also be heterogeneous.In this perspective,based on previous studies,we argue that networks can be regarded as the infrastructure of scientometrics in the sense that networks can be used to represent scientometric data.Then the task of answering various scientometric questions related to this data becomes an algorithmic problem in the corresponding network.

The need to develop tailored tools for improving the quality of thematic bibliometric analyses: Evidence from papers published in Sustainability and Scientometrics

Purpose: The aim of this article is to explore up to seven parameters related to the methodological quality and reproducibility of thematic bibliometric research published in the two most productive journals in bibliometrics, Sustainability(a journal outside the discipline) and Scientometrics, the flagship journal in the field.Design/methodology/approach: The study identifies the need for developing tailored tools for improving the quality of thematic bibliometric analyses, and presents a framework that can guide the development of such tools. A total of 508 papers are analysed, 77% of Sustainability, and 23% published in Scientometrics, for the 2019-2021 period.Findings: An average of 2.6 shortcomings per paper was found for the whole sample, with an almost identical number of flaws in both journals. Sustainability has more flaws than Scientometrics in four of the seven parameters studied, while Scientometrics has more shortcomings in the remaining three variables.Research limitations: The first limitation of this work is that it is a study of two scientific journals, so the results cannot be directly extrapolated to the set of thematic bibliometric analyses published in journals from all fields.Practical implications: We propose the adoption of protocols, guidelines, and other similar tools, adapted to bibliometric practice, which could increase the thoroughness, transparency, and reproducibility of this type of research.Originality/value: These results show considerable room for improvement in terms of the adequate use and breakdown of methodological procedures in thematic bibliometric research, both in journals in the Information Science area and journals outside the discipline.
