Abstract

Objective: To analyze the distribution of HLA-DRB1 and HLA-DQB1 alleles and its correlation with IFN-γ, IL-2, IL-6, IL-10 in HPV16 infected women with advanced cervical carcinoma.

Methods: We collected 137 blood samples of cervical carcinoma patients diagnosed by pathology as cervical cancer in stage IIb-IVb before the treatment, and we gathered 175 blood samples of healthy women living in the local. We determined the genetic subtypes of HLA-DRB1 and HLA-DQB1, and we measured the concentration of IFN-γ, IL-2, IL-6 and IL-10. We compared the difference of cytokines in patients with different clinical stages and the healthy in the control group. According to genetic subtypes of HLA-DRB1 and HLA-DQB1, we also compared the concentration of cytokine (CK) in different genetic subtypes.

Results: Eight HLA-DRB1 alleles and four HLA-DQB1 alleles were found. There were not significant differences between each allele in the concentration of IFN-γ, IL-2, IL-6, and IL-10.

Conclusion: HLA-DRB1*07, HLA-DQB1*02 and HLA-DQB1*03 were the differentially expressed gene in HPV16 infected patients with advanced cervical cancer. There may be correlations between the occurrence, development of cervical cancer and IFN-γ, IL-2, IL-6, IL-10.
