dc.description.abstract | Activated B-cell like subtype of diffuse large B-cell lymphoma (DLBCL) is characterized by chronic active B-cell receptor signaling and a constitutive activation of the nuclear factor kappa B pathway. As a driving force of nuclear factor kappa B overactivity, myeloid differentiation primary response gene 88 (MYD88) L265P mutation occurs in activated B-cell like DLBCL. However, the MYD88 L265P mutation has not yet been studied in conjunction with MYD88 protein expression in DLBCL cases. Thus, we investigated MYD88 expression in 124 DLBCL specimens by immunohistochemistry. In addition, the MYD88 L265P mutation was examined by polymerase chain reaction and direct DNA sequencing. MYD88 was overexpressed in 38.7% (48/124) of DLBCL cases. MYD88 was expressed in the cytoplasm of lymphoma cells. MYD88 overexpression was associated with older age (P=.016) and tumor recurrence (P=.007). In univariate analysis, MYD88 overexpression was correlated with shortened disease-free survival (DFS) of DLBCL (P=.013) and non germinal center B-cell like DLBCL (P=.034). In multivariate analysis, MYD88 overexpression was an independent factor for reduced DFS (P=.025). MYD88 L265P mutation was found in 6.5% (8/124) of DLBCL cases. All but 1 case were of non germinal center B-cell like subtype. The MYD88 L265P mutation was not associated with MYD88 expression (Spearman rho=-0.074) and clinicopathologic parameters of DLBCL. The data indicate that high MYD88 expression is significantly associated with tumor recurrence and shortened DFS in patients with DLBCL. In addition, the incidence of MYD88 L265P mutation in Korea is much lower than previously reported. Thus, MYD88 may be crucial for lymphoma progression, independent of MYD88 L265P mutation.
