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.

Rockburst prediction and prevention in underground space excavation

The technical challenges associated with deep underground space activities have become increasingly significant.Among these challenges,one major concern is the assessment of rockburst risks and the instability of rock masses.Extensive research has been conducted by numerous scholars to mitigate the risks and prevent occurrences of rockburst through various assessment methods.Rockburst incidents commonly occur during the excavation of hard rock in underground environments,posing severe threats to personnel safety,equipment integrity,and operational continuity.Thus,it is crucial to systematically document real cases of rockburst,allowing for a comprehensive understanding of the underlying mechanisms and triggering conditions.This understanding will contribute to the advancement of rockburst prediction and prevention methods.Proper selection of an appropriate rockburst assessment method is a fundamental aspect in underground operations.However,there is a limited number of studies that summarize and compare different prediction and prevention methods of rockburst.This paper aims to address this gap by analyzing global trends using CiteSpace software since 1990.It discusses rockburst classification and characteristics,comprehensively reviews research findings related to rockburst prediction,including empirical,simulation,mathematical modeling,and microseismic monitoring methods.Additionally,the paper presents a compilation of current rockburst prevention measures.Notably,the paper emphasizes the significance of control strategies,which provide key insights into the effective utilization of stored energy within rock.Finally,the paper concludes by suggesting six directions for implementing intelligent management techniques to mitigate hazards during underground operations and reduce the probability of rockburst incidents.
