Human leukocyte antigen associations in basal cell carcinoma.
Basal cell carcinoma is the most common form of skin cancer and is one in which both host and environmental factors are thought to play a role in its pathogenesis. For an investigation of the role of human leukocyte antigen (HLA)-associated variations in genetic susceptibility, thirty-one patients with multiple basal cell carcinomas were typed for HLA-A, B, C, and DR antigens. Patients were compared with both local and appropriate ethnic group controls. No statistically significant association with HLA-A, B, or C antigens was noted in any group. However, a significant increase in HLA-DR1 was noted in non-Irish, non-Ashkenazi patients. A tendency toward a decrease in HLA-DR3 was also noted among patients of Irish or Ashkenazi Jewish descent. The role of HLA-associated genetic factors in this form of skin cancer needs further investigation.
