Six databases (PubMed, Google Scholar, Scopus, Embase, ArXiv, and IEEE) were screened for publications without any time limitation. The QUADAS-2 tool was utilized to assess quality.

On QUADAS-2 assessment, only three studies had a low risk of bias across all applicability domains. For segmentation studies, 0.97 was reported for accuracy, 0.97 for sensitivity, 0.98 for specificity, and 0.92 for Dice. For classification studies, accuracy was reported as 0.99, sensitivity 0.99, specificity 1.0, Dice 0.95, F1 score 0.98, and AUC 0.99.

Patients exhibiting high ANXA5 expression in these cells demonstrated poor differentiation, aggressive invasion patterns, and heightened lymph node metastasis risk, contributing to poorer postoperative outcomes. Remarkably, ANXA5 in fibroblast-like cells emerged as an independent risk factor impacting survival in OSCC patients. Gene set enrichment analysis (GSEA) highlighted ANXA5's involvement in key pathways like epithelial-mesenchymal transformation (EMT), TGF-beta signaling, and hypoxia, which correlated with adverse clinical outcomes in OSCC.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>ANXA5 emerges as a significant prognostic biomarker for OSCC, potentially influencing its metastasis via the EMT pathway.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16588,"journal":{"name":"Journal of Oral Pathology & Medicine","volume":"53 8","pages":"538-543"},"PeriodicalIF":2.7,"publicationDate":"2024-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141468790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recruited 76 OSCC patients to analyze METTL5 mRNA and protein expression using RT-qPCR and western blot. Additionally, we analyzed METTL5 expression and its correlation with clinical features, patient prognosis, immune cell infiltration, and biological pathways using the TCGA-HNSCC dataset, which primarily consists of OSCC samples.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Our findings revealed significant overexpression of METTL5 in OSCC tissues compared to normal tissues. The high expression of METTL5 is associated with advanced cancer stages, higher tumor grades, nodal metastasis, and poorer patient outcomes, indicating its involvement in cancer progression. In silico functional analysis revealed that METTL5 plays a role in multiple biological pathways, highlighting its importance in cancer biology. Moreover, METTL5 has complex relationships with immune regulatory genes, suggesting its potential role in shaping the tumor immune microenvironment.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>METTL5 is a promising candidate for the prognosis and therapeutic intervention of OSCC. Its overexpression in cancer tissues, association with clinical features, and intricate links to immune regulatory networks underscore its significance in this malignancy. This study contributes to a deeper understanding of the complex factors influencing OSCC, and provides a foundation for future research and potential clinical applications.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16588,"journal":{"name":"Journal of Oral Pathology & Medicine","volume":"53 8","pages":"521-529"},"PeriodicalIF":2.7,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141468792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
