Abstract
Aim: A recent study shows that YB-1-related biomarkers affect the prognosis of patients with natural killer/T-cell lymphoma (NKTCL). The aim of this study was to determine whether there is an association between YB-1 expression and the prognosis of patients with early-stage extranodal nasal-type NKTCL. Materials & methods: To clarify the roles of YB-1 in early-stage extranodal nasal-type NKTCL, we used immunohistochemical studies to examine YB-1 expression in 36 early-stage extranodal nasal-type NKTCL specimens. Results: Subsequently, YB-1 expression was correlated with clinicopathologic parameters. Higher expression of YB-1 was associated with an increased potential for relapse, poor disease-free survival and reduced overall survival. Discussion: Higher expression of YB-1 could be an independent risk factor for poor prognosis in patients with early-stage extranodal nasal-type NKTCL. Understanding the biology of YB-1-mediated pathways may lead to novel therapeutic strategies for early-stage extranodal nasal-type NKTCL.
