title: Plasmatic cytokine network in patients with laryngeal carcinoma after surgical treatment.
abstract: Alterations in host immunity, inflammation, angiogenesis and metabolism are all prominent clinical features in patients with laryngeal squamous cell carcinoma (LSCC). Although the origin of the signals and mechanisms underlying these responses are not well understood, their local and systematic nature suggest that squamous cell carcinoma-produced cytokines with proinflammatory and immunoregulatory activity may contribute to the pathogenesis of LSCC. In order to gain a better insight into the roles and relationships of the cytokines, we investigated serum IL-6, IL-10 and IL-12 concentrations in LSCC patients under baseline conditions and after surgery. In comparison with controls, all the patients had higher plasma IL-10 concentrations before surgical treatment (T0), while plasma IL-6 and IL-12 concentrations were higher in 22 (84.6%) and 24 patients (92.3%). The differences in plasma IL-6, IL-10 and IL-12 concentrations at T0 and T1 were statistically significant (p<0.001, p<0.0046 and p<0.011). Our finding suggest that plasma cytokines are overexpressed in LSCC patients. There was an independent increase in plasma IL-6 levels before and after surgical treatment. Furthermore, the up- and down-regulation of plasma IL-10 and IL-12 suggest a regulatory relationship between them.
