摘　　要：目的探讨新疆地区汉族鼻咽癌患者人类白细胞抗原(HLA)A2基因型表达差异与临床特征的关联性,比较HLA-A*02阳性和阴性患者的近期疗效和远期疗效的差异。方法收集新疆医科大学附属肿瘤医院2007年1月-2014年1月接受全程IMRT放疗的初治汉族鼻咽癌患者143例的外周血标本,采用聚合酶链反应/序列特异性引物的方法提取DNA样本,进行HLA-A分型的检测,并将患者分为HLA-A*02阳性组和阴性组,比较两组患者一般临床特征和近、远期疗效。结果 143例汉族鼻咽癌患者共检出HLA-A基因型13个,HLA-A*02表达患者94例,基因频率为38.7%,构成比为42.66%(122/286)。HLA-A*02阳性组和阴性组患者的年龄、性别、病理类型、TNM分期、近期疗效差异无统计学意义。两组患者的5年总生存率(OS)、无瘤生存率(DFS)及无远处转移生存率(DMFS)分别为84.43%和76.53%(χ2=0.22,P=0.637)、82.79%和90.18%(χ2=0.09,P=0.762)、71.23%和85.90%(χ2=0.09,P=0.759),差异无统计学意义,HLA-A*02阳性组患者的5年生存率略低于阴性组患者。结论新疆汉族鼻咽癌的HLA-A基因型中,HLA-A*02仍为优势基因。HLA-A*02基因型可能不能作为估计鼻咽癌患者预后的独立因素,需要联合其他因素进行综合分析。Objective To analysis the relationship between the different human leukocyte antigen （HLA）A genotype and the clinical characteristics,in Han nasopharyngeal carcinoma（NPC）patients,also analyse the differences of the outcome between the HLA-A＊02 and other genotype.Methods Collect One hundred and forty-three Han newly diagnosed NPC patients who received the whole IMRT at the Affiliated Tumor Hospital of Xinjiang Medical University between January 2007 and 2014.Blood samples were taken before treatment,polymerase chain reaction/sequence specific primers method was used to extract DNA,tested the HLA-A genotype, and divided the patients into 2 groups, HLA-A＊02 positive and negative, compared the differences between the clinical characteristics of these two groups,compared the difference between the recent curative effect.Results In all 143 patients,13 HLA-A alleles had been tested,and a 〈br〉 total of 94 cases were detected 122 HLA-A＊02 gene,the gene frequency was 38.7%,the proportion was 42.66% （122/286）.Age,gender,pathological pattern,TNM stages and the short-termtheropeutic effect of the patients of HLA-A＊02 positive and negative groups in the general clinical characteristics were seen no obvious distribution differences ,with the recent curative effect is also did not see obvious difference. Five years of two groups of patients with OS,DFS,DMFS,（Kaplan-Meier method was used to analyse two groups of patients 5-year overall survival （OS）,disease-free survival （DFS）,no distant metastasis and survival rate （DMFS）,compared two groups of survival differences）.Respectively,84.43% and 76.53%（χ2=0.22,P =0.637）,82.79% and 90.18% （χ2=0.09,P =0.762）,71.23% and 85.90% （χ2=0.09,P=0.759）,those differences were no obvious difference,statistical analysis of HLA-A＊02 positive patients survival rates was lower than negative one.Conclusion The Han nationality in Xinjiang HLA-A genotype of nasopharyngeal carcinoma,HLA-A＊02 is still the dominant genes.HLA-A＊02 genotype cannot e
