Description
Summary:# Introduction Diffuse large B-cell lymphoma (DLBCL) is the most common neoplasm of the lymphatic system. Treatment and clinical management are difficult in the relapsed/refractory (R/R) setting. Chimeric antigen receptor (CAR) T cells are genetically engineered using autologous patient lymphocytes and have shown very promising results in the treatment of relapsed and refractory cases of DLBCL. # Methods A 64-year-old male patient with refractory DLBCL and central nervous system (CNS) involvement after 9 lines of therapy was treated with CD19-specific CAR T cell therapy at the Department of medical oncology and hematology at the University Hospital of Zurich and followed-up for 10 weeks. # Results Autologous lymphocytes were successfully harvested and transfected/expanded for CAR T cell production. Conditioning chemotherapy and CAR T infusion was well tolerated. Post-infusion side effects were mild (cytokine release syndrome \[CRS\] grade 1–2), with limited signs of neurotoxicity. Ten weeks after CAR T cell therapy, an excellent response could be documented via PET-CT. The CNS lesion disappeared as assessed via cranial MRI. # Conclusion CD19-targeted CAR T cell therapy is a revolutionary treatment option for heavily pretreated R/R DLBCL even in the setting of CNS involvement.
