PG - 109-114 LID - S0003-9969(17)30180-2 [pii] LID - 10.1016/j.archoralbio.2017.06.003 [doi] AB - OBJECTIVES: The aim of this study was to identify the possible association between TLR polymorphisms and an increased risk of developing head and neck cancer, including oral (OSCC) and laryngeal squamous cell carcinoma (LSCC), and oral potentially malignant disorders, such as oral lichenoid disease (OLD), including oral lichen planus (OLP) and oral lichenoid lesions (OLL). DESIGN: This case-control study included 40 OSCC, 35 LSCC, 175 OLD (129 OLP and 46 OLL) patients and 89 healthy controls, all of them from the Basque Country, Spain. Genetic polymorphisms in TLR1, TLR2, TLR4, TLR6, TLR9, and TLR10 were genotyped by TaqMan((R)) assays or pyrosequencing. RESULTS: The chi-square analysis showed that the variant A of the SNP TLR2-rs4696480 polymorphism significantly increased the risk of OSCC (p=0.03) and OLL (p=0.02). CONCLUSIONS: The TLR2-rs4696480 polymorphism may be relevant to OSCC and OLL susceptibility in this population encouraging further studies on the TLR2 pathway and its possible association with this group of oral potentially malignant disorders and oral cancer. This may also prove the use of TLR polymorphisms as risk markers for oral and laryngeal cancer. CI - Copyright (c) 2017 Elsevier Ltd. All rights reserved.
