Klinički i imunološki faktori prognoze kod bolesnika sa B difuznim krupnoćelijskim nehočkinskim limfomom

Patients with diffuse large B cell non Hodgkin lymphoma (DLBCL) have a very heterogeneous clinical course and prognosis. There is a constant need to find new prognostic factors to assess risk in patients. Immunohistochemical biomarkers correlated with clinical and biochemical parameters, as well as prognostic scores may be predictors of risk patients. The main aim of this study was to analyze the survival of patients with diffuse large B- cell non Hodgkin lymphoma according to clinical prognostic factors and expression of proteins involved in the activation of immune response, cell cycle regulation and programmed cell death (Ki-67, Bcl-2, Bcl-6 , CD10, CD5, CD138, MUM1 and the presence of mutations L265P MyD88), by classifying patients according to current prognostic scoring systems comparing the clinical and immunological factors prognosis in patients with DLBCL, make a proposal for a prognostic scoring system that would unite the two groups of parameters. All patients was determined by clinical stage of the disease. During the study were collected and processed by clinical and laboratory parameters, that are known to have a prognostic value and that it was possible to collect for all patients included in the study. It is about gender, age, Ann Arbor clinical stage of disease, extranodal number of cities affected processes, performance status, presence of "B" symptoms, hemoglobin, platelet count, erythrocyte sedimentation rate, C-reactive protein levels, beta 2 microglobulin, serum albumin and serum LDH. Histopathological material consisted of 68 paraffin blocks. From immunohistochemical parameters were analyzed: CD5, CD10, Ki- 67, Bcl-2, Bcl-6, MUM1 by EnVision procedure. Molecular-genetic study of gene polymorphism MyD88 L265P was used genomic DNA isolated from fixed tissue in paraffin patients with DLBCL. Polymerization chain reaction were amplified by DNA segments within which the SNP is tested gene MyD88 L265P. Statistical analyzes included the use of nonparam
