The purpose of this study was to evaluate the contribution ofSHISA3promoter methylation to laryngeal squamous cell carcinoma (LSCC).SHISA3promoter methylation status and expression were determined using methylation-specific polymerase chain reaction (MSP) and quantitative real-time PCR (qRT-PCR) in 93 paired LSCC and adjacent normal tissues, respectively. Furthermore, the regulatory function of theSHISA3promoter fragment was analyzed using a luciferase reporter assay. The results reveal that there is a significant increase inSHISA3methylation in LSCC tissues compared with corresponding nontumor tissuesP=4.58E-12. The qRT-PCR results show a significant association betweenSHISA3methylation and expression in LSCCP=1.67E-03. In addition, the area under the receiver operating characteristic curve was 0.91. Consequently, a log-rank test and multivariate Cox analysis suggest thatSHISA3promoter hypermethylation is a predictor of poor overall survival for LSCC (log-rankP= 0.024; HR = 2.71; 95% CI = 1.024–7.177;P= 0.047). The results indicate thatSHISA3promoter hypermethylation might increase the risk of LSCC through regulation of gene expression and is a potential diagnostic and prognostic biomarker for LSCC.
