Zusammenfassung:New therapies for relapsed/refractory diffuse large B-cell lymphoma (r/rDLBCL) have emerged in recent years, but there have been no comprehensive quantitative comparisons of the efficacy of these therapies. In this study, the efficacy characteristics of 11 types of treatment strategy and 63 treatment regimens were compared by model based meta-analysis. We found that compared with monotherapy, association therapy had significant benefits in terms of overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). However, whereas treatment regimens involving chemotherapy contributed to significant improvements in ORR and PFS, OS was not improved. In terms of treatment strategy, we identified chemotherapy in association with immunotherapy sequential autologous stem cell transplantation (ASCT), the association of two different types of immunotherapies, chemotherapy sequential ASCT, chemotherapy in association with immunotherapy, and chemotherapy in association with two types of immunotherapies as showing better efficacy. With respect to specific treatment regimens, we found that the following had better efficacy: rituximab in association with inotuzumab ozogamicin; rituximab in association with carmustine, etoposide, cytarabine, and melphalan sequential ASCT (R-BEAM+ASCT); lenalidomide in association with rituximab, etoposide, cisplatin, cytarabine, and methylprednisolone; iodine-131 tositumomab in association with BEAM sequential ASCT; and chemotherapy sequential chimeric antigen receptor T-cell immunotherapy, with median OS of 48.2, 34.2, 27.8, 25.8, and 25 months, respectively. Moreover, with respect to association therapy, there was a strong correlation between the 6-month PFS and 2-year OS. The findings of this study provide the necessary quantitative information for clinical practice and clinical trial design for the treatment of r/rDLBCL. [Display omitted]
