Epigenetic, genetic predisposition and epidemiological risk factors were suggested to be involved in the carcinogenesis of oral cancer. In this study, we focused on the associations of MET single-nucleotide polymorphisms (SNPs) to oral cancer susceptibility and clinicopathological characteristics. The MET SNPs rs41736, rs41739, rs1621, and rs33917957 in 1198 controls and 1318 male patients with oral cancer were analyzed with real-time polymerase chain reaction. Our results revealed that the cigarette smokers among the oral cancer patients who carried the
