目的

分析幽门螺杆菌(Hp)感染与早期胃癌CYP2C19、白细胞分化抗原14(CD14)基因多态性的关系,并分析对内镜黏膜下剥离术(ESD)后短期复发的影响。

方法

回顾性选择2018年7月至2023年7月哈尔滨医科大学附属第一医院收治的行ESD治疗的早期胃癌患者201例,根据合并Hp感染情况分为Hp感染组(n=93)和非Hp感染组(n=108),聚合酶链反应-限制性片段长度多态性法检测CYP2C19、CD14基因多态性,分析Hp感染与早期胃癌患者ESD术后短期复发的关系,多因素Cox回归分析ESD术后短期复发的风险因素。

结果

Hp感染组PM型构成比明显高于非Hp感染组(P<0.05);Hp感染组TT基因型、T等位基因频率明显高于非Hp感染组(P<0.05);Hp感染组ESD术后短期复发率明显高于非Hp感染组(P<0.05);早期胃癌患者中,Hp感染(HR=2.783,95% CI 1.214~6.430)、CD14基因多态性(HR=2.894,95% CI 1.101~7.614)是ESD术后短期复发的风险因素(P<0.05)。

结论

CYP2C19、CD14基因多态性与早期胃癌患者Hp感染有关,CYP2C19基因PM型以及CD14基因TT基因型、T等位基因可能增加患者Hp感染风险,Hp感染、CD14基因多态性是影响早期胃癌患者ESD术后短期复发的危险因素。

Objective

To analyze the relationship between Helicobacter pylori (Hp) infection and gene polymorphisms of CYP2C19 and leukocyte differentiation antigen 14 (CD14) in patients with early gastric cancer and analyze its influence on short-term recurrence after endoscopic submucosal dissection (ESD).

Methods

A total of 201 patients with early gastric cancer who underwent ESD in the First Affiliated Hospital of Harbin Medical University were selected retrospectively between July 2018 and July 2023, and were divided into Hp infection group (n=93) and non-Hp infection group (n=108) according to Hp infection status. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the gene polymorphisms of CYP2C19 and CD14. The relationship between Hp infection and short-term recurrence of patients with early gastric cancer after ESD was analyzed, and multivariate Cox regression analysis was used to analyze the risk factors affecting the short-term recurrence after ESD.

Results

The composition ratio of PM in Hp infection group was significantly higher than that in non-Hp infection group (P<0.05). The frequencies of TT genotype and T allele were significantly higher in Hp infection group than those in non-Hp infection group (P<0.05). The short-term recurrence rate after ESD in Hp infection group was significantly higher compared with that in non-Hp infection group (P<0.05). In patients with early gastric cancer, Hp infection (HR=2.783, 95% CI: 1.214-6.430) and gene polymorphisms of CD14 (HR=2.894, 95% CI: 1.101-7.614) were risk factors affecting the short-term recurrence after ESD (P<0.05).

Conclusion

The gene polymorphisms of CYP2C19 and CD14 in patients with early gastric cancer are related to Hp infection. The PM of CYP2C19 gene and TT genotype and T allele of CD14 gene may increase the risk of Hp infection, and Hp infection, gene polymorphisms of CD14 are risk factors that affect the short-term recurrence of patients with early gastric cancer after ESD.
