Oral squamous cell carcinoma (OSCC) shows low 5-year survival; early treatment greatly reduces mortality and morbidity. Saliva is a non-invasive sample, with good potential to discover biomarkers for early detection.NanoLC-MS/MS served to analyze saliva proteome from control subjects (n=35) and OSCC patients T1 (n=29), T2 (n=36), T3 (n=14) and T4 (n=21) stages. Identified biomarkers were verified by Western blot and ELISA assays.NanoLC-MS/MS analysis of salivary proteins between 10 and 15kDa identified S100A8, hemoglobin delta and gamma-G globin in T3 and T4 stage OSCC as well as S100A7 in T1 and T2 stage OSCC. Western blot and ELISA indicated positive correlation between salivary S100A8 increment and tumor size stage. High level of S100A8 appeared in 3.4, 13.9, 92.9, and 100
