摘要:

目的 探讨肿瘤坏死因子β(TNF-β)基因+252位点多态性和幽门螺旋杆菌(Helicobacter pylori, Hp)感染对非贲门型胃癌易感性的影响。方法 选取2015年3月至2018年12月在福建医科大学附属第一医院住院的非贲门型胃癌患者215例为病例组,以同期215例健康体检者为对照组。按Lauren标准将胃癌患者进行病理分型,分析各TNF-β基因+252位点多态性基因型分布与Hp感染、非贲门胃癌临床病理学特征之间的关系。结果与Hp感染阴性者相比,Hp感染阳性者患胃癌的危险度更高(OR=1.881, 95%CI 1.277~2.770)。与G/G基因型相比,G/A和A/A型患者患胃癌危险度更高[OR值分别为1.950(1.151~3.303)、2.226(1.260~3.932)]。在对照组中,Hp感染阴性和阳性患者基因型差异无统计学意义(χ2=2.801, P=0.246)。在病例组中,Hp感染阳性患者G/A、A/A比例高于Hp感染阴性患者(χ2=6.265, P=0.044)。肠型胃癌患者中G/A+A/A基因型频率相比对照组增加(χ2=11.325, P=0.003)。携带TNF-β基因+252位点A等位基因与Hp感染存在交互作用。结论TNF-β基因+252位点G/A基因型和A/A基因型与非贲门型胃癌的易感性有关, TNF-β基因与Hp感染存在交互作用。

Abstract:

Objective To evaluate the association of tumor necrosis factor-β (TNF-β) +252 gene polymorphisms and H.pylori (Hp) infection with the susceptibility to non-cardiac gastric cancer. MethodsA total of 215 patients with non-cardiac cancer and 215 healthy control subjects were recruited from the First Affiliated Hospital of Fujian Medical University between March, 2015 and December, 2018. Pathological typing of gastric cancer was performed according to Lauren’s criteria, and the correlation of TNF-β+252 genotypes and Hp infection with the clinicopathological characteristics of the patients was analyzed. ResultsCompared with Hp-negative patients, Hp-positive patients had a significantly increased risk for gastric cancer (OR=1.881, 95%CI: 1.277-2.770). Compared with G/G genotype of TNF-β +252, the genotypes G/A and A/A were associated with significantly increased risks for gastric cancer [OR=1.950 (1.153-3.303) and 2.226 (1.260-3.932), respectively]. In the control group, no significant difference was found in the genotype distribution between the Hp-negative and Hp-positive subjects (Chi-square=2.801, P=0.246). In the case group, the proportion of G/A and A/A genotypes was significantly greater in Hp-positive patients than in Hp-negative patients (Chi-square=6.265, P=0.044). The G/A+A/A genotype frequencies were significantly higher in patients with intestinal gastric cancer than in the control group (Chi-square=11.325, P=0.003). There was an interaction between the allele A in TNF-β gene +252 and Hp infection. ConclusionHp infection increases the susceptibility to non-cardiac gastric cancer, which is also associated with TNF-β gene +252 G/A and A/A genotypes
