摘要:

目的: 探讨重组人肿瘤坏死因子α诱导蛋白3(TNFAIP3)基因的遗传变异对食管鳞癌(ESCC)患者预后的影响。方法: 本研究纳入175例食管鳞癌根治术患者。在手术前收集患者的外周血5 mL用来提取基因组DNA,对rs583522位点进行基因分型,并对基因型和基线临床资料,以及患者的长期预后情况进行关联性分析。结果: 野生型AA型相对于AG/GG型患者者来说具有明显较晚的肿瘤分期(P<0.001)。AA型的患者更容易复发(P=0.022)。生存分析结果表明AA型患者相对于AG/GG型患者具有明显较差的总生存期(OS),两种基因型患者的中位OS分别为38.2和48.5个月(P=0.017)。结论: TNFAIP3多态性位点rs583522可能通过影响了该基因的功能,进而使得不同基因型的ESCC患者具有不同的恶性程度。因此TNFAIP3基因rs583522位点可以作为评价食管鳞癌患者预后的生物标记物。

Abstract:

AIM: To investigate the influence of genetic variation of tumor necrosis factor alpha induced protein 3 (TNFAIP3) on prognosis among esophageal squamous cell carcinoma patients. METHODS: A total of 175 patients underwent complete surgical resection of esophageal squamous cell carcinoma were included in this study. 5 mL peripheral blood specimen of the patient was collected. Genomic DNA were extracted and genotype of rs583522 were analyzed. The association between genotype and baseline clinical characteristics and prognosis were analyzed. RESULTS: Wild type AA genotypes showed advanced tumor stages compared with those of homozygous G-allele carriers (P<0.001). Patients with an AA genotype were significantly more likely to experience relapse (P=0.022). Survival analysis revealed a significant difference in overall survival between different genotype groups (P=0.017). CONCLUSION: rs583522 genotypes can be used as biomarkers to evaluate the prognosis of patients with esophageal squamous carcinoma.

Key words: esophageal squamous carcinoma, TNFAIP3, polymorphism, prognosis
