Refractory recurrence of patients with diffuse large B cell lymphoma inclusion/exclusion standard subjects in a signed written informed consent, according to the results of genotyping, divided the patients into MCD, TP53, BN2, EZB, ST2, NOS, N1, a total of 7 kinds of types. New targeted drugs were added based on typing results: Etoposide for MCD and BN2, Decitabine for TP53, Chidamide for EZB, Tofacitinib for ST2, and pomalidomide for N1 and NOS. Patients with stable disease (SD) and disease progression (PD) were withdrawn from the trial. Patients with partial response (PR) and complete response (CR) were treated for another course of treatment. After 3 courses of treatment, PET-CT was used to evaluate the efficacy. Patients with CR/PR, aged ≤65 years, qualified and willing for transplantation, were treated with autologous hematopoietic stem cell transplantation (ASCT); Patients who did not meet the above requirements or failed to collect autologous hematopoietic stem cells were placed on new targeted drug maintenance therapy for up to 12 months; If patients were evaluated as SD and PD after 3 cycles, they were dropped out of the trial and treated with other regiments. New targeted drugs combined with R-ICE and ASCT were evaluated every 3 months in the first year and every 6 months in the second and third years after treatment.
A single-center, open, single-arm clinical study of the efficacy and safety of a novel targeted agent in combination with R-ICE in the treatment of relapsed and refractory diffuse Large B-cell lymphoma.
