Abstract:
Objective:To investigate the efficacy and safety of sequential therapy of targeting CD19 and CD22 chimeric antigen receptor T-cell (CAR-T) following autologous stem cell transplantation (ASCT) in treatment of renal diffuse large B-cell lymphoma (DLBCL) with central nervous system (CNS) recurrence.Methods:The clinical data of 1 renal DLBCL patient with CNS recurrence admitted to Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology in May 2019 were retrospectively analyzed. The patient received sequential therapy of targeting CD19 and CD22 CAR-T following ASCT. The relative indicators of the primary disease remission at 1, 3, 6, 12, 18 and 24 months after therapy were analyzed, and relevant literature was reviewed.Results:The male patient aged 23 years had CNS recurrence after 8 courses of R-CHOP chemotherapy and then he received sequential therapy of targeting CD19 and CD22 CAR-T following ASCT. During the process of treatment, this patient developed grade 1 cytokine release syndrome and his condition was well controlled after active treatment. The white blood cell and platetes were successfully implanted. CNS symptoms along with immature cells in cerebrospinal fluid disappeared completely. Liquid biopsy was used to dynamically monitor the residue disease of the patient and the duration of remission period lasted 26 months. This patient developed tuberculosis one year after treatment and recovered from anti-tuberculosis agents.Conclusions:Sequential therapy of targeting CD19 and CD22 CAR-T following ASCT provides a novel therapeutic approach for renal DLBCL with CNS recurrence. Especially for patients who are neither sensitive to conventional chemotherapy nor CAR-T therapy alone, this regimen may improve remission rate and survival.
