摘　　要：目的探索药代动力基因单核苷酸多态性(SNP)与食管鳞癌患者术后无病生存期的关系,用于评估手术患者预后。方法以77例食管鳞癌术后患者为研究对象,选择ATP结合盒亚家族B成员1(ABCB1)rs1045642、rs2032582、rs3213619,ATP结合盒亚家族G成员2(ABCG2)rs2231137、rs2231142,ATP结合盒亚家族C成员1(ABCC1)rs246221和ATP结合盒亚家族C成员2(ABCC2)rs3740066这7个SNP行基因测序,采用Cox回归模型评估遗传变异和无病生存之间的关系,并采用半贝叶斯收缩方法对多次检验和小样本量进行校正。结果在显性基因模型下,ABCC2 rs3740066的次要等位基因与无病生存期缩短有关[粗HR(95%CI)为4.623(1.111~19.241),P=0.035;校正HR(95%CI)为4.290(1.010~18.215),P=0.048]。结论药物代谢动力学基因ABCC2 rs3740066单核苷酸多态性与食管鳞癌患者术后无病生存期有关。Objective To explore the relationship between single nucleotide polymorphism(SNP)of pharmacokinetic genes and postoperative disease-free survival in patients with esophageal squamous cell carcinoma,and to evaluate the prognosis of patients undergoing surgery.Methods Seventy-seven patients with esophageal squamous cell carcinoma were selected in the study.Seven SNPs-ATP binding cassette subfamily B member 1(ABCB1)rs1045642,rs2032582,rs3213619,ATP binding cassette subfamily G member 2(ABCG2)rs2231137,rs2231142,ATP binding cassette subfamily C member 1(ABCC1)rs246221 and ATP binding cassette subfamily C member 2(ABCC2)rs3740066 were sequenced,and the relationship between genetic variation and disease-free survival was evaluated by Cox regression model.Semi-Bayesian shrinkage method was applied to correct for multiple comparison and small sample size issues.Results With the dominant genetic model,the minor allele of ABCC2 rs3740066 was significantly associated with shorter disease-free survival[crude hazard ratio(cHR)95%CI=4.623(1.111-19.241),P=0.035,adjusted hazard ratio(aHR)95%CI=4.290(1.010-18.215),P=0.048].Conclusion The SNP rs3740066 of pharmacokinetic gene ABCC2 is associated with postoperative disease-free survival in patients with esophageal squamous cell carcinoma.
