烟碱乙酰胆碱受体是吸烟行为和烟草致癌的重要调节因子。我们研究了中国人群中 CHRNB3-A6 变异 rs13280604 与食管鳞状细胞癌 (ESCC) 的关系。进行了两项独立的病例对照研究。第一项病例对照研究由来自中国北方的 866 名 ESCC 患者和 1621 名健康对照组成,第二项病例对照研究由来自中国南方的 853 名 ESCC 患者和 860 名无关对照组成。使用逻辑回归模型评估 rs13280604 与癌症风险的关联。我们发现,在北方[比值比(OR),1.42,95%置信区间(CI),1.19-1.70,P = 1.1×10(-4)]和中国南方(OR,1.56,95% CI,1.26-1.93, P = 5.2×10(-5)),以及两项研究的合并人群(OR,1.44,95% CI,1.26-1.65,P = 8.7×10(-8))。我们的结果表明,这种 CHRNB3-A6 变异赋予 ESCC 风险的易感性。然而,未来需要更大规模的研究来验证我们的发现。
Nicotinic acetylcholine receptors are important regulators of smoking behavior and tobacco carcinogenesis. We studied the association of the CHRNB3-A6 variant rs13280604 in relation to esophageal squamous cell carcinoma (ESCC) in Chinese populations. Two independent case-control studies were conducted. The first case-control study, consisted of 866 ESCC patients and 1621 healthy controls from Northern China, and the second case-control study consisted of 853 ESCC patients and 860 unrelated controls from Southern China. A logistic regression model was used to evaluate the associations of rs13280604 with cancer risk. We found that Rs13280604 GG/AG genotypes were significantly associated with increased risk for ESCC in both case-control studies from Northern [odds ratio (OR), 1.42, 95% confidence interval (CI), 1.19-1.70, P = 1.1×10(-4)], Southern China (OR, 1.56, 95% CI, 1.26-1.93, P = 5.2×10(-5)), and the combined population of both studies (OR, 1.44, 95% CI, 1.26-1.65, P = 8.7×10(-8)), respectively. Our results suggest that this CHRNB3-A6 variant confers susceptibility to ESCC risk. However, future larger studies are needed to validate our finding.
