Abstract: | Esophageal cancer is one of the ten most common cancers in the world and has poor prognosis. Apoptosis is considered a fundamental component in cancer pathogenesis. We conducted a hospital-based case–control study to evaluate the genetic effects of 16 apoptosis associated single nucleotide polymorphisms (SNPs) on esophageal cancer development. A total of 380 esophageal squamous cell carcinoma (ESCC) cases and 380 controls were recruited for this study. Genotypes were determined using a custom-by-design 48-Plex SNPscan? Kit. The caspase8 (CASP8) rs1035142 G>T polymorphism was associated with increased risk of ESCC by heterozygote comparison, homozygote comparison, a dominant genetic model and a recessive genetic model. However, no significant association was detected between the other 15 SNPs and ESCC risk. Stratified analyses indicated a significantly increased risk of ESCC associated with CASP8 rs1035142 G>T polymorphism was evident among all subgroups. These findings indicated that the functional polymorphism CASP8 rs1035142 G>T might contribute to ESCC susceptibility. |
