Objective: Despite all the recent advancements, larynx cancer has shown no improvement in survival rates. The aim of this study was to investigate the expressions of toll-like receptor (TLR)-2,-3, and-4 genes, and determine any relationships with the histopathologic characteristics of the disease.Methods: This retrospective study included 50 subjects who underwent total or partial laryngectomy with an open surgical method for larynx squamous cell carcinoma. Measurements of TLRs-2,-3, and-4 expression values were taken with quantitative real time-polymerase chain reaction in normal tissue and tumor tissue samples of the patients.Results: Evaluations were made of TLR-2,-3, and-4 mRNA expressions according to 2- increment increment CT calculations in 50 subjects with larynx cancer. When the tumor tissue was compared with the healthy tissue from the same subjects, reductions were determined in TLR expression in 86%, 84%, and 82%, respectively. This reduction in each gene expression was statistically significant (p<0.001). No statistically significant correlation was determined between the change in TLR-2,-3, and-4 expression and the histopathologic characteristics of the disease.Conclusion: The data obtained in this study demonstrated that TLR-2,-3, and-4 expressions were reduced in larynx squamous cell cancer. The results of further studies targeting these genes would be useful in the diagnosis and treatment of the disease.
