It is believed that an individual's hereditary factors may be involved in the development of esophageal cancer (EC). The present study recruited 721 esophageal squamous cell carcinoma (ESCC) cases and 1208 controls and explored the roles of single nucleotide polymorphisms (SNPs) in the interleukin-4 (IL-4), IL-10, and herpesvirus entry mediator (HVEM) genes in contributing to ESCC risk. IL-4, IL-10, and HVEM SNPs were analyzed by employing an SNPscan method. After adjustment for body mass index (BMI), smoking, drinking, age and gender, we identified that the rs2070874 T>C locus in IL-4 gene decreased the risk of ESCC (CC vs. TT: P=0.008; CC vs. TT/TC: P=0.010). After a stratified analysis, we suggested that the IL-4 rs2070874 T>C variants might be a protective factor for ESCC in male, ≥63 years old, never smoking, drinking and BMI < 24 kg/m2 subgroups. In addition, we identified that the rs2243263 G>C polymorphism in IL-4 gene was a risk factor for ESCC development in the BMI ≥ 24 kg/m2 subgroup (GC vs. GG: P=0.030 and GC/CC vs. GG: P=0.018). We identified an association of the IL-4 rs2070874 T>C SNP with the decreased susceptibility of ESCC in stage I/II subgroup. Finally, we found an association of the IL-10 rs1800872 T>G SNP with a worse differentiation (TG vs. TT: P=0.048 and GG/TG vs. TT: P=0.032). In conclusion, the findings indicate a potential importance of IL-4 rs2070874 T>C, IL-4 rs2243263 G>C and IL-10 rs1800872 T>G SNPs in the development of ESCC.
据信,个体的遗传因素可能与食管癌(EC)的发展有关。本研究招募了 721 例食管鳞状细胞癌(ESCC)病例和 1208 例对照,探讨了白细胞介素-4(IL-4)、白细胞介素-10(IL-10)和疱疹病毒进入介体(HVEM)基因中的单核苷酸多态性(SNP)在 ESCC 风险中的作用。采用 SNPscan 方法分析 IL-4、IL-10 和 HVEM SNP。在调整体重指数(BMI)、吸烟、饮酒、年龄和性别后,我们发现 IL-4 基因中的 rs2070874 T>C 位点降低了 ESCC 的风险(CC 与 TT:P=0.008;CC 与 TT/TC:P=0.010)。分层分析后,我们提示 IL-4 rs2070874 T>C 变体可能是男性、年龄≥63 岁、从不吸烟、饮酒和 BMI<24 kg/m2 亚组中 ESCC 的保护因素。此外,我们发现 IL-4 基因中的 rs2243263 G>C 多态性是 BMI≥24 kg/m2 亚组中 ESCC 发展的危险因素(GC 与 GG:P=0.030;GC/CC 与 GG:P=0.018)。我们发现 IL-4 rs2070874 T>C SNP 与 I/II 期亚组 ESCC 易感性降低有关。最后,我们发现 IL-10 rs1800872 T>G SNP 与分化程度较差有关(TG 与 TT:P=0.048;GG/TG 与 TT:P=0.032)。总之,这些发现表明 IL-4 rs2070874 T>C、IL-4 rs2243263 G>C 和 IL-10 rs1800872 T>G SNP 可能在 ESCC 的发展中具有重要作用。
