Megjegyzések:	Oral squamous cell carcinoma (OSCC) is the 6th most common malignancy worldwide. Regrettably Hungary occupies top places of statistics regarding OSCC incidence, therefore there is a high need for developing sensitive and specific biomarkers to improve early detection. The saliva as a biological fluid for the detection of diagnostic and prognostic biomarkers has become increasingly important. Different research groups used saliva and potential salivary biomarkers specific for different countries were identified. In this study 14 proteins previously reported in the literature as significantly elevated in saliva of OSCC patients were examined. Collection of human saliva is a simple, non-invasive and cost-effective approach for screening large populations. A targeted proteomics method was developed and optimized for catalase, thioredoxin, S100A9, galectin-3 binding protein, cytokeratin 21, profilin, CD44 and CD59. Moreover the relative amounts of these proteins was determined in the saliva of OSCC patients and controls. In case of IL-1?, IL-1?, IL-6, IL-8, TNF-? and VEGF, the salivary concentrations were determined using Luminex-based multiplex immunobead assay.Based on our results, the levels of protein S100A9, thioredoxin, IL-6 and TNFa were significantly altered in OSCC patients compared to controls. The ROC analysis revealed the S100A9, thioredoxin and IL-6 as potential OSCC biomarkers applicable for the Hungarian population. In order to verify the results obtained by Luminex and SRM analyses, ELISA experiments were carried out on a multi centric study from the patients of the four University Medical Centers (Debrecen, Budapest, Pécs and Szeged) in Hungary. The salivary concentrations of IL-6, protein S100A9 and thioredoxin were determined. Based on our results the IL-6 seem to be useful biomarkers for OSCC detection in the Hungarian population.This research was supported by the Hungarian Scientific Research Fund OTKA K105034.
