Since the 1990s, the standard of care for the treatment of relapsed/refractory diffuse large B-cell lymphoma (DLBCL) had been salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (HDT-ASCT) in patients with a chemotherapy-sensitive remission.

However, promising results from the recent TRANSFORM and ZUMA-7 trials evaluating the efficacy of CAR T-cell therapy versus HDT-ASCT for second line relapsed/refractory DLBCL have sought to challenge this standard of care. While these studies have established a new standard for the treatment of early relapsed and primary refractory DLBCL, significant differences in the trial design between these studies and limitations with the timing of randomization during the disease course warrant a thoughtful interpretation of the results.

Additionally, the financial burden and logistic challenges of CAR T-cell administration and limited access to these therapies continue to be ongoing issues. Despite the encouraging results from these trials, HDT-ASCT continues to have a role in the treatment of DLBCL, especially in disease relapsing 12 months after initial therapy, and in chemo sensitive disease with a good response to salvage chemotherapy.

Ongoing studies evaluating novel salvage regimens for use prior to HDT-ASCT, and future studies evaluating the role of CAR T-cell therapy in chemo sensitive disease will help determine the continued role of HDT-ASCT for relapsed/refractory DLBCL.
