PG - 535-41 AB - We performed a retrospective analysis on the human leukocyte antigen (HLA) data of 53 consecutive Chinese patients with high-risk childhood acute lymphoblastic leukemia (ALL) diagnosed from 1989 to 2003. A significantly higher frequency of HLA-B67 in the male relapse group of patients [OR, 23.08; 95% CI, 5.31-100.36; p = 0.0042; for statistical significance after Bonferroni correction (Bc) p (Bc) < 0.0083] was identified after Bonferroni correction. Although not surviving the Bonferroni correction, gender effects on the association were also observed with HLA-A11, HLA-A32, HLA-A33, and HLA-B22, which were however more prevalent in the female patients and particularly those developing relapse. Two patients with HLA-A29 and HLA-B7 revealed significantly shortened survivals, suggestive of their potential prognostic impacts. Notably, for the first time, we found a significant correlation of leukocyte count with HLA types, where HLA-A33 (p = 0.006) or HLA-B17 (p < 0.001) signifies higher leukocytosis at presentation. Taken together, our findings support the involvement of HLA in Chinese high-risk childhood ALL.
