BACKGROUND: The aim of this study was to investigate the biology of laryngeal squamous cell carcinoma (SCC) to develop effective novel treatment modalities. METHODS: Serum concentrations of interleukin (IL)-10, IL-12, and transforming growth factor-β (TGF-β) were evaluated in 50 patients with laryngeal SCC and 15 controls. Results were compared according to tumor-node-metastasis (TNM) classification criteria. RESULTS: IL-12 and TGF-β levels were not different between the early- and late-stage patients and controls. Tumor classification or nodal involvement was not associated with IL-12 and TGF-β levels. Patients with laryngeal SCC had significantly more detectable serum IL-10 levels than those of controls, given that IL-10 could be detected in only 1 early-stage and 9 late-stage patients, but not in the control group (p = .003). IL-10 was increasingly detectable with advanced T classification (p = .009) and nodal involvement (p = .008). CONCLUSIONS: Serum IL-12 or TGF-β levels were not affected with disease activity and classification; however, serum IL-10 levels were correlated with both parameters.
