Oral diseases, such as periodontitis, salivary gland diseases, and oral cancers, significantly challenge health conditions due to their detrimental effects on patient's digestive functions, pronunciation, and esthetic demands. Delayed diagnosis and non-targeted treatment profoundly influence patients' prognosis and quality of life. The exploration of innovative approaches for early detection and precise treatment represents a promising frontier in oral medicine.

Background and Aims:Hepatocellular carcinoma(HCC)cases with small nodules are commonly treated with radi-ofrequency ablation(RFA),but the recurrence rate remains *** study aimed to establish a blood signature for identifying HCC with metastatic traits ***:Data from HCC patients treated between 2010 and 2017 were retrospectively collected.A blood signature for meta-static HCC was established based on blood levels of alpha-fetoprotein and des-γ-carboxy-prothrombin,cell-free DNA(cfDNA)mutations,and methylation changes in target genes in frozen-stored plasma samples that were collected before RFA *** HCC blood signature was validated in patients prospectively enrolled ***:Of 251 HCC patients in the retrospective study,33.9% experienced recurrence within 1 year *** HCC blood signature identified from these patients included des-γ-carboxy-prothrombin≥40mAU/mL with cfDNA mutation score,where cfDNA mutations occurred in the genes of TP53,CTNNB1,and TERT *** signature effectively predicted 1-year post-RFArecurrence of HCC with 92% specificity and 91% sensitivity in the retrospective dataset,and with 87% specificity and 76% sensitivity in the prospective dataset(n=32 patients).Among 14 cases in the prospective study with biopsy tissues available,positivity for the HCC blood signature was associated with a higher HCC tissue score and shorter distance between HCC cells and ***:This study established an HCC blood signature in pre-RFA blood that potentially reflects HCC with metastatic traits and may be valuable for predicting the disease’s early recurrence post-RFA.
