This study suggests that HLA-DQB1*03 and DRB1*07 alleles may influence the immune response to HPV16 infection and increase the risk of CSCC among the Uighurs and Hans in China.
In this study, the HLA-A, -B, and -DRB1 alleles among 100 southern Chinese women with cervical squamous cell carcinoma (SCC) were compared to 254 controls.
Most multilocus results were similar for SCC that contained HPV16; a notable exception was A*0101-B*0801-Cw*0701-DRB1*0301-DQB1*0201 and its subsets, which were associated with HPV16-positive SCC (odds ratio, 0.5; 95% confidence interval, 0.3-0.9).
In conclusion, our meta-analysis confirms the apparent association between certain HLA-DRB1 allele families and alleles and CSCC, suggesting that oncogenesis in this disease may be related to defects in immunoregulation.
Increased risks of SCC were associated with DRB1*0401-DQB1*0301 (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.1-2.7) and DRB1*1101-DQB1*0301 (OR, 2.5; 95% CI, 1.4-4.5), and decreased risks were associated with DRB1*0301-DQB1*02 (OR, 0.7; 95% CI, 0.5-1.0) and DRB1*13-DQB1*06 (OR, 0.6; 95% CI, 0.4-0.9) haplotypes.
