Refractory DLBCL was defined in this study as the first-line standard immunochemotherapy regimen 4 cycles of treatment failed to achieve PR; 2). Relapsed DLBCL refers to re-progression after>= 2 lines of treatment, or after autologous stem cell transplantation to stabilize the disease (whether the high-risk patients with recurrence within 6 months are included is at the discretion of the investigator); 3). Diffuse large B patients with follicular transformation are allowed to enroll 4. At least one measurable lesion according to Lugano 2014 criteria 5. Bone marrow hematopoietic function is basically normal, blood routine: white blood cell count> 3000/uL, absolute neutrophil count >= 1.5x10 9 /L (granulocyte colony-stimulating factor is allowed), platelet count >= 75x10 9 /L (blood transfusion is allowed to reach The minimum platelet count)), hemoglobin >= 8.0g/dL (permit pre-transfusion of red blood cells or use of recombinant human erythropoietin). If the peripheral blood index is abnormal due to lymphoma invading the bone marrow or spleen, the investigator can judge whether it is suitable for enrollment; 6.
