Summary
Brief summary (as posted)
Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma。The majority of refractory patients have PD-L1 expression due to P53 mutations, some of which account for about 10% of DLBCL.Our department has found that in refractory DLBCL with high PD-L1 expression, cedilizumab monotherapy is also more effective and has reversed chemotherapy resistance.The aim of this study was to determine whether the addition of sindilizumab to the R-CHOP regimen could improve the objective efficiency of DLBCL patients with P53 mutation with PD-L1 expression and to see if it could prolong patient survival.
