Variability in host immunogenetic background is important in determining the overall cellular immune response to HPV infections. Objective: To determine whether the HLA-DQ or HLA-DR genes, or others in their vicinity, are associated with cervical cancer. Methods: Markers covering the entire HLA region were genotyped in a large sample of CIN and cervical cancer patients and in controls (311 CIN, 695 cervical cancer, 115 family controls, and 586 unrelated controls). Results: Two markers were associated with susceptibility to cervical neoplasia, G511525 and MICA. G511525, close to the region containing the HLA-DQ and HLA-DR genes, was most strongly associated, showing a decrease in frequency of allele 221 from 6.7% to 3.3% in patients with squamous cell cancer (SCC). An association was found for MICA (allele 184) with SCC (odds ratio (OR)β€Š=β€Š1.31 (95% confidence interval, 1.13 to 1.53); homozygotes, ORβ€Š=β€Š1.48 (1.06 to 2.06)). No associations were observed with adenocarcinoma or CIN. Conclusions: There is an association of the region containing the HLA-DQ and HLA-DR genes with the risk of developing squamous cell carcinoma. An increased risk was observed for carriers of allele 184 at the MICA locus, in particular for homozygotes, suggesting a recessive effect. ER -
