Objective: This study aims to investigate ectopic expression of histone deacetylase 6 (HDAC6) in diffuse large B-cell lymphoma (DLBCL).
Methods: This study analyzed patients with DLBCL (n=132) and reactive lymph node hyperplasia (n=32) diagnosed in our hospital from December 2007 to May 2016. Correlation between HDAC6 expression and clinical pathologic features was analyzed by χ2 test. The significant differences between the 5-year overall survival (OS) or progression-free survival (PFS) and high HDAC6 expression as well as DLBCL clinic-pathological features including age, International Prognostic Index (IPI) score, Eastern Cooperative Oncology Group score, lactate dehydrogenase (LDH), and germinal center B-cell-like were assessed by univariate and multivariate analyses.
Results: HDAC6 high-expression percentage in DLBCL was significantly higher than that in the control group. The proportion of IPI score of 0–2, 5-year OS, and PFS in the high-expression group, which had lower percentage of patients with increased LDH and β2-microglobulin, were significantly higher than those in the low-expression group. Moreover, HDAC6 mRNA expression in HDAC6 protein low expression was markedly lower than that in protein high expression. The multivariate analysis demonstrated that HDAC6 high expression was an independent prognostic factor for patients with DLBCL.
Conclusion: HDAC6 high expression might be a prognostic factor for DLBCL.
