Oral verrucous hyperplasia (OVH) is a critical oral potentially malignant disorder, yet biomarkers predicting its progression to oral cancer remain elusive. This study aimed to identify non-invasive biomarkers by isolating extracellular vesicles (EVs) from the saliva of OVH patients. Using liquid chromatography-mass spectrometry (LC-MS), we performed parallel proteomic and metabolomic analyses on EV fractions. Proteomic profiling identified three candidate proteins—Cystatin S, Cornulin, and Fibrinogen Gamma Chain—that effectively differentiated progressive from non-progressive OVH. Complementary metabolomic analysis revealed significant dysregulation in arachidonic acid metabolism and steroid biosynthesis pathways. Despite challenges related to low salivary EV yields, this dual-omics approach highlights specific EV-derived proteins and metabolites as promising indicators for the early risk assessment of oral squamous cell carcinoma (OSCC). These findings provide a vital foundation for future multi-omics integration to validate progression biomarkers.
