Journal of Hematology Oncology 2011 4 31 http content 4 1 31 JOURNAL OF HEMATOLOGY ONCOLOGY RAPID COMMUNICATION Open Access High nuclear expression of STAT3 is associated with unfavorable prognosis in diffuse large B-cell lymphoma Wu ZL1 Song YQ1 Shi YF2 and J Zhu1 Abstract Background The purpose of the study was to investigate the expression and prognostic value of STAT3 in diffuse large B-cell lymphoma DLBCL . Methods Seventy-four DLBCL patients from 2001 to 2007 were reviewed in the study. The STAT3 expression in their tumor tissues was examined using the immunohistochemistry IHC method and evaluated for its association with clinicopathological parameters. Results Strong nuclear staining of STAT3 and phosphorylated-STAT3tyr705 P-STAT3 were observed in 19 cases and 24 cases respectively and the expression levels were highly consistent between them P . The high nuclear expression of STAT3 was more frequent in the non-germinal center B cell-like non-GCB DLBCL than that in the GCB subtype but not reaching significance P . The high nuclear expression of STAT3 was found to be correlated with poor overall survival OS P . Multivariate Cox regression analysis showed that the STAT3 expression was an independent prognostic factor for DLBCL patients regardless of CHOP or R-CHOP regimen used as the first-line therapy. Conclusion STAT3 is more frequently expressed in non-GCB DLBCL than that in GCB subtype and its strong nuclear expression is correlated with poor OS in DLBCL. Introduction Diffuse large B-cell lymphoma DLBCL is defined by the World Health Organization WHO Classification as a heterogeneous entity encompassing morphologic and genetic variants and variable clinical presentations and outcomes 1 . It accounts for 80 of aggressive lymphomas 2 . International Prognostic Index IPI is currently used to predict the prognosis in DLBC 3 but its role is limited 4 . Molecular subtypes of germinal center B cell-like GCB
