Abstract:
OBJECTIVE:To investigate the efficacy of multiple protein expressions and clinical features on the threapeutic effect and prognosis of patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).
METHODS:The clinical data of 68 DLBCL patients were collected and analyzed retrospectively. The clinical staging was performed according to Ann Arbor staging; the risk grading was performed by IPI index; the DLBCL typing (germinal center and non-germinal center) was performed according to B cell source; the expression of Ki67，BCL-2, BCL-6, C-MYC, MUM1 and CD10 protein was detected by immunohistochemistry method; the patients were divided into R-CHOP group(50 cases) and CHOP group(18 cases) according to chemotherapy regimen of using rituximab or not; finally, the related factors affecting the prognosis of patients(PFS and OS) were analysed statistically by using SPSS 22.0 software according to sex, age, erythrocyte sedimentation rate (ESR), lactate dehydrogenase(LDH) and use of rituximab or no, as well as the above-mentioned clinical indicators.
RESULTS:IPI grade high-risk, elevated LDH, positive expression of BCL-2 protein and negative expression of BCL-6 protein were independent prognostic factors for progression-free survival (PFS); elevated LDH and negative expression of BCL-6 protein were independent prognostic factors for overall survival time (OS); multivariate analysis showed that elevated LDH and positive expression of BCL-2 protein were independent prognostic factors for progression-free survival (PFS). The overall survival time (OS) associated with ESR, IPI classification and BCL-6 protein expression.
CONCLUSION:The expression of BCL-2 and BCL-6 protein and some clinical features can be used as predictors of clinical efficacy for DLBCL. Choosing the treatment regimen combined with ritu-ximab can further improve the survival and prognosis of DLBCL patients.
