High-dose chemotherapy supported by autologous stem cell support/transplantation (HDT/ASCT) has been a standard of care over the last two decades in patients with relapsed or refractory(R/R) diffuse large B-cell lymphoma (DLBCL), which is sensitive to salvage chemotherapy. HDT/ASCT for high-risk DLBCL in upfront setting remains controversial, so it is not recommended for clinical practice. Various promising salvage chemotherapy regimens have been reported in phase 2 studies; however, two large randomized phase 3 studies showed similar efficacy of R-ICE vs. R-DHAP and R-GDP vs. R-DHAP. Since the registry data shows feasibility and efficacy of HDT/ASCT in elderly R/R DLBCL patients, older age (> 65 years) itself is not a contraindication for HDT/ASCT. Rituximab maintenance failed to demonstrate a significant benefit compared with observation only after HDT/ASCT. While sensitive R/R DLBCL might be cured by HDT/ASCT even in third-line therapy, the prognosis of insensitive R/R DLBCL is extremely poor. Further study to establish treatment strategies for high-risk patients defined by prognostic factors or biomarkers, and insensitive patients is warranted.
