Abstract: Objective To study the molecular genetic characteristics and immunophenotype of diffuse large B -cell lymphoma (DLBCL),thus to provide evidence in further research.Methods 92 patients with DLBCL were selected.Immunophenotype was classified by Hans method,bcl -2 and bcl -6 were detected by fluorescence in situ hybridization(FISH).The relationship between immunophenotype and genes expression was analyzed by SPSS 19.0. Results There were GCB with 28 cases(30.43%)and non GCB with 64 cases(69.57%).Bcl -2 gene abnormality was more found in GCB(χ2 =38.39,P <0.05),there was no difference of bcl -6 abnormality between GCB and non GCB(χ2 =0.56,P >0.05).There was no correlation between bcl -2 translocation and bcl -6 translocation(r =0.095,P >0.05),but there was significant correlation between bcl -2 amplification and bcl -6 translocation(r =0.750,P <0.01).There were no correlations between the location and immunophenotype,bcl -2,bcl -6(r =0.174, r =0.205,r =0.188,all P >0.05 ).Conclusion Bcl -2 gene abnormality was more found in GCB,but the relationship between bcl -2 and bcl -6 is not clear.There may be no correlation between location and molecular genetic.
