title: Serum Levels of IL-1b, IL-6, TNF-a, sTNF-RI and CRP in Patients with Oral Cavity Cancer.
abstract: Pro-inflammatory cytokines, such as interleukin-1b (IL-1b), interleukin-6 (IL-6) and tumor necrosis factor- (TNF-a) play an essential role in the regulation of immune response to, and may have prognostic significance in, cancer. The aim of this study was to examine the relationship between the serum levels of IL-1b, IL-6 and TNF-a as well as the concentrations of soluble TNF receptor I (sTNF-RI) and C-reactive protein (CRP) in patients with squamous cell carcinoma of oral cavity. Results obtained were confronted with squamous cell carcinoma antigen (SCC) concentrations. IL-1b IL-6 and TNF-a serum levels as well as sTNF-RI and CRP concentrations were higher in patients than in controls. The increased serum levels appeared to be related to the clinical stage of disease. There was a correlation between IL-1b and sTNF-RI. IL-6 and IL-1b correlated with CRP levels. The mean concentrations of SCC were also elevated. IL-6 and sTNF-RI seemed to be the most sensitive parameters in early stages and may be used as additional markers in oral cancer.
