  • Efficacy and safety of salvage therapeutic regimens for the relapsed/refractory diffuse large B cell lymphoma: a network meta-analysis

    ObjectiveTo analyze the efficacy and safety of various treatment strategies for patients with refractory/recurrent diffuse large B-cell lymphoma (r/r-DLBCL) by network meta-analysis. MethodsThe PubMed, EMbase and Cochrane Library databases were searched to collect randomized controlled trials (RCTs) and clinical controlled trials related to the objectives of the study from inception to November 16th, 2022. After two investigators independently screened the literature, extracted data and evaluated the risk of bias of the included studies, a network meta-analysis was performed using R 4.2.2 software. ResultsA total of 8 RCTs and 11 non-randomized controlled trials were included, involving 2 559 cases. The treatment regimen included chemotherapy, immunochemotherapy, chemotherapy combined with ADC, immunochemotherapy combined with ADC, ASCT based regimen, CAR-T based regimen, ASCT combined with CAR-T, immunomodulators, small molecule inhibitors, and rituximab combined with small molecule inhibitors. The ranking probability results showed that the top three complete remission (CR) rates among all schemes were ASCT combined with CAR-T, chemotherapy combined with ADC, and immune modulators; The top three overall response rates (ORR) were chemotherapy combined with ADC, ASCT combined with CAR-T, and ASCT. The CAR-T regimen had a higher rate of severe neutropenia; The severe thrombocytopenia rate of ASCT regimen was relatively high; There was no significant difference in the incidence of SAEs among the other options. ConclusionASCT combined with CAR-T and chemotherapy combined with ADC have the best therapeutic effects on r/r-DLBCL. However, the specific protocol to be adopted requires clinical doctors to combine actual conditions, comprehensively consider the efficacy and side effects, and develop personalized treatment strategies for r/r-DLBCL patients.
