ABSTRACT
<p><b>OBJECTIVE</b>To explore the influence of BCL6, MYC, P53 genes abnormalities can on the prognosis of diffuse large B-cell lymphoma (DLBCL), and to identify independent prognostic factors for DLBCL in order to facilitate clinical prognosis and selection of stratification treatment for the patients.</p><p><b>METHODS</b>Sixty five newly diagnosed DLBCL pathological specimens were collected from 2009 to 2012. Interphase fluorescence in situ hybridization technique (I-FISH) was used to detect the status of BCL6, MYC and P53 genes. Clinical factors were combined with immunohistochemical results for multiple-factor survival analysis.</p><p><b>RESULTS</b>The rates of BCL6 gene rearrangement, P53 gene deletion and MYC rearrangement were 21.5% (14/65), 35.4% (23/65) and 7.7% (5/65), respectively. BCL6 rearrangement group has obviously poorer overall survival (OS)(P< 0.05). COX proportional hazards model analysis showed that gender, BCL6 protein, BCL6 rearrangement, Ki67 index were prognosis factors independent of international prognostic index (IPI).</p><p><b>CONCLUSION</b>BCL6 can influence the prognosis of patients with DLBCL at gene and protein levels and both are independent prognostic factors for DLBCL.</p>
