Autoimmune gastritis studies and gastric cancer: True renaissance or bibliometric illusion

World Journal of gastroenterology 2024年第32期30卷 3783-3790页

A bibliometric analysis of studies dedicated to autoimmune gastritis(AIG)recently published demonstrated a noteworthy surge in publications over the last three *** can be explained by numerous publications from different regions of the world reporting the results of several studies that stimulated reassessment of our view of AIG as a precancerous ***-up studies and retrospective analyses showed that the risk of gastric cancer(GC)in AIG patients is much lower than expected if the patients ever being infected with Helicobacter pylori(***)were *** low prevalence of precancerous lesions,such as the incomplete type of intestinal metaplasia,may explain the low risk of GC in AIG patients because the spasmolytic polypeptide-expressing metaplasia commonly observed in AIG does not involve clonal reprogramming of the gastric gland and can be considered as an adaptive change rather than a true precancerous ***,changes in gastric secretion due to the progression of gastric atrophy during the course of AIG cause changes in the gastric microbiome,stimulating the growth of bacterial species such as streptococci,which may promote the development of precancerous lesions and ***,Streptococcus anginosus exhibited a robust proinflammatory response and induced the gastritis-atrophy-metaplasia-dysplasia sequence in mice,reproducing the wellestablished process for carcinogenesis associated with *** studies in ***-naïve patients evaluating gastric microbiome changes during the long-term course of AIG might provide an explanation for the enigmatic increase in GC incidence in the last decades in younger cohorts,which has been reported in economically developed countries.

MicroRNAs(miRNAs)are recognized for their involvement in the regulation of gene expression and exhibit significant potential in both the prognostic assessment and treatment of hepatocellular carcinoma(HCC).HCC,like other tumors,seldom occurs in isolation;instead,it evolves within a microenvironment featuring oncogenic and tumor-suppressive *** combined with suitable delivery vehicles,miRNA technology provides the capability to directly engage with these elements,thereby hindering tumor formation and *** research in this domain holds the promise of enabling a more efficacious and multi-modal treatment approach for HCC in the near future.
