[Current status and future prospects of diffuse large B-cell lymphoma treatment].

R-CHOP therapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) has been used as the standard treatment regimen for patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL), since the introduction of rituximab in the early 2000s. Recently, polatuzumab vedotin and anti-CD19 chimeric antigen receptor T-cell (CAR-T) therapy have been introduced as potential treatment options for relapsed or refractory DLBCL. The effectiveness of polatuzumab vedotin, rituximab, cyclophosphamide, doxorubicin, and prednisone for newly diagnosed CD20-positive DLBCL, except for the low-risk group of the international prognostic index, was reported in 2022. Bispecific antibodies such as epcoritamab, mosunetuzumab, and glofitamab, anti-CD19 antibody drug tafasitamab combined with lenalidomide, CD19 antibody drug conjugate loncastuximab tesirine, oral selective inhibitor of nuclear export selinexor, and several new agents have been investigated for DLBCL. For non-germinal center B-cell type DLBCL, R-CHOP combined with acalabrutinib is being evaluated. This review summarizes the current standard of care for DLBCL and outlines the recently introduced therapeutic agents or those that are under development in Japan.
