Objective To investigate the association of human leucocyte antigen-DRB1 alleles and expression of HLA-DR antigen with Hepatocellular carcinoma(HCC) in Han population of Jilin area. Methods HLA-DRB1 alleles in 61 patients with chronic hepatitis B, 44 patients with hepatic cirrhosis, 62 patients with HCC, and 50 healthy controls were analyzed by using polymerase chain re-action/sequence specific primer technique. Meanwhile the expression of HLA-DR antigen in HCC tis-sues, tissues adjacent to HCC and nomal liver tissues was detected with immunohistochemical method. Results The frequency of HLA-DRB1 * 1201-3 allele in chronic hepatitis B group was higher than that in healthy control group(17. 21% vs. 8. 00% ,P=0. 0427, RR=2. 391). The frequency of HLA-DRB1 * 0701 allele in chronic hepatitis B group, hepatic cirrhosis group and HCC group was markedly higher than that in healthy control group(11. 48% vs. 2. 00%, P=0. 0066, RR=6.35; 12.50% vs.2.00%, P=0.0046, RR=7.00; 11.29% vs. 2.00%, P=0.0073, RR=6.236). The frequency of HLA-DRB1 * 1501-5 allele in HCC group was higher than that in healthy control group(18. 55% vs.9.00%, P=0. 0423, RR= 2. 303). The expression of HLA-DR antigen was negative in hepatocytes of nomal liver tissues and tissues adjacent to HCC, while 34.2% of HCC tissues expressed DR antigen which distributed on the cytomembrane and/or in cytoplasm intensively. Expression of DR antigen in HCC was not associated with tumor size, tumor lymphocyte infiltration and tumor metastasis(P>0.05) ,but it was associated with histological grade. The rate of HLA-DR antigen expression in well-differenciated cases was higher than that in poorly-differenciated ones(P<0. 05). Conclusions Alleles of HLA-DRB1 * 1201-3 and HLA-DRB1 * 0701 were closed associated with chronic hepatitis B. HLA-DRB1 * 0701 was also closed associated with hepatic cirrhosis. Alleles of HLA-DRB1 * 1501-5, HLA-DRB1 * 0701 and expression quantity of HLA-DR antigen were associated with HCC in Han popula-tion of Jilin area.
