Since June 2016, he had received treatments with four lines including anti-CD20 monoclonal antibody combined with chemotherapy, chemotherapy only and chimeric antigen receptor T cell (CAR-T). However, the disease relapsed or progressed after all treatments. Therefore, the patient had received 6 cycles of pola combined with rituximab since December 2019. Unexpected adverse events were not found during the treatment. The evaluation of clinical efficacy was complete remission after the end of treatment. The progression-free survival time was more than 13 months with follow-up until January 2021.Conclusion:Pola initially shows good efficacy and safety in treatment of patients with relapsed/refractory DLBCL.
