ObjectivesTo compare the efficacy and side effects of salvage chemotherapy between etoposide, methylprednisolone, cytarabine and cisplatin (ESHAP) and ifosfamide, carboplatin and etoposide plus dexamethasone (DICE) for relapsed or refractory diffuse large B-cell lymphoma (DLBCL).MethodsMedical records of patients with relapsed or refractory DLBCL receiving second-line ESHAP or DICE chemotherapy with or without rituximab from January 2007 to November 2022 were retrospectively reviewed. The primary objective was progression-free survival (PFS). The secondary objectives were overall survival (OS), overall response rate (ORR) and adverse events (AEs).ResultsSeventy patients were enrolled including 21 patients who received ESHAP and 49 patients who received the DICE regimen. Six patients (28.6%) and 19 patients (38.8%) in the ESHAP and DICE groups underwent ASCT, respectively. The ORR was 47.6% for ESHAP and 53.1% for DICE (p = .67). The two-year PFS was 14.3% for ESHAP and 26.5% for DICE (p = .33) with median PFS of 5 months and 14 months, respectively (hazard ratio 0.74; 95% CI 0.39-1.36, p = .330). The two-year OS was 14.3% for ESHAP and 26.5% for DICE (p = .37) with median OS of 8 months and 19 months, respectively. Patients in ESHAP group have more all-grade renal impairment than DICE group (23.8% vs. 6.1%, p = .047).Discussion And ConclusionsEfficacy between ESHAP and DICE regimens as salvage chemotherapy for relapsed or refractory DLBCL was not significantly different in terms of two-year PFS, two-year OS and ORR. DICE regimen had less renal AE than ESHAP.
