摘要

Evidence regarding the efficacy and safety of DeVIC (dexamethasone, etoposide, ifosfamide, and carboplatin) therapy for relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL) is critically lacking. This retrospective study analyzed 78 patients with r/r DLBCL who received DeVIC therapy at a single institution. The overall response rate was 37.2%, comprising 21.8% complete and 15.4% partial responses. A total of 15 (19.2%) patients proceeded to transplantation or cellular therapy. The 3-year overall survival and progression-free survival were 28.2 and 18.0%, respectively. Multivariable analyses identified refractoriness to prior therapy and elevated serum lactate dehydrogenase (LDH) levels as significant predictors of poor response and survival. Decision tree models confirmed these findings, revealing that relapsed cases with low LDH had the most favorable outcomes. Hematological toxicities were frequent, with febrile neutropenia in 52.6% and infection-related mortality in 3.8% of patients. Those with central nervous system involvement had a dismal prognosis, underscoring the need for novel therapeutic approaches. These findings highlight the potential role of DeVIC therapy in selected patients with r/r DLBCL and provide insights into optimizing bridging strategies and subsequent immunocellular therapies.
