HLA-DRB1 and diffuse large B-cell lymphoma: More specifically, Alcoceba et al. (Alcoceba et al., 2013) compared 250 DLBCL cases to 1940 controls of European origin and found that the phenotypic frequency of HLA-DRB1*01 was higher (29% vs. 19.5%, OR = 1.69, p-value = 0.0008) in DLBCL patients than in the control group.
