Difference of Bcl-6 and c-myc gene translocation between Xinjiang Uygur and Han diffused large B-cell lymphoma subtypes / 中国肿瘤临床

ABSTRACT

Objective:To investigate the clinical significance of Bcl-6, c-myc gene abnormalities in Xinjiang Uygur and Han dif-fused large B-cell lymphoma (DLBCL) subtypes. Methods:Bcl-6, c-myc gene was detected by fluorescence in situ hybridization in 233 patients with DLBCL . A relationship was observed among Bcl-6, c-myc gene translocation, and clinical data in DLBCL patients. In addition, a difference was observed among Bcl-6, c-myc gene translocation, and different ethnic groups in different subtypes of DLB-CL. Results:Among the 233 patients, 51 cases (21.89%) had rearranged Bcl 6 gene, and 39 cases (16.74%) had rearranged c-myc gene. Bcl-6 gene translocation and expression was related with age, gender, disease location, clinical stage, and LDH levels (P>0.05), but was not related with nationality , international prognostic index score, extranodal involvement, B symptoms, DLBCL subtypes, and recent efficacy (P0.05), but was not related with nationality, IPI score, extranodal involvement, B symptoms, and recent effica-cy (P0.05). By con-trast, in the Uygur and Han non-GCB groups, Bcl-6, c-myc gene translocation showed significant difference (P>0.05). Conclusion:Bcl-6, C-myc gene translocation was related with age, gender, disease location, clinical stage, and LDH levels. Bcl-6 gene translocation was also correlated with different subtypes of DLBCL.
