Although these observations are preliminary and constrained by the modest cohort size, they may offer an initial framework for exploring OVOL1 as a potential supportive diagnostic and prognostic biomarker. Further studies, including larger multi-institutional cohorts and mechanistic investigations, are needed to validate these preliminary results and to better establish the potential clinical applicability of OVOL1 in salivary gland tumors. This evidence concerns the gene OVOL1 and tumor of salivary gland.
