Abstract: Objective: Papillary thyroid carcinoma (PTC) is the most frequent
types of thyroid malignancies. Several genes may be involved in susceptibility
of thyroid cancer including Human Leukocyte Antigens (HLA). The association of
thyroid carcinoma with HLA alleles has been previously studied in other
populations and certain HLA alleles were shown to be either predisposing or
protective. The aim of this study was to determine the association between
HLA-DR and papillary thyroid carcinoma in an Iranian population. Design: HLA-DR antigen frequencies were determined in patients with papillary
thyroid carcinoma (N=70) and non-related healthy controls (N=180) using
PCR -SSP. Main Outcome: We found that HLA-DRB1*04 frequency was
significantly higher in our patients compared to the controls [P=0.02, OR;
1.9, 95% CI (1.04–3.57)]. Conclusions: Our results revealed
HLA-DRB1*04 as predisposing factor in papillary thyroid carcinoma in Iranian
population. This confirms the previous findings for associations between
HLA-DRB1 and differentiated carcinomas in other populations.
