Abstract:
8548 Background: High-dose chemotherapy (HDT) followed by autologous stem-cell transplantation (ASCT) is considered standard in the treatment of patients with relapsed or refractory aggressive peripheral T-cell lymphoma (PTCL). However, the optimal salvage regimen before ASCT has not yet been established. Methods: We retrospectively analyzed 31 patients with relapsed or refractory aggressive PTCL after anthracycline based first-line chemotherapy who received either DexaBEAM (n=16) or ICE (n=15) regimen as first salvage chemotherapy followed by HDT and ASCT between 1996 and 2009. The median patient age was 46 years (range, 18-66) in the DexaBEAM group and 40 years (range, 17-59) in the ICE group. Patients were included independent of WHO stage and IPI score. Results: The overall response rate (OR) was significantly higher for patients treated with DexaBEAM (69%) as compared to the ICE group (20%; P=0.01), with higher complete response (CR; 38% vs. 7%) as well as partial response (PR; 31% vs. 13%) rate. Changing regimen due to failure of the first salvage therapy, 12 patients initially receiving ICE still achieved an OR of 58% (33% CR, 25% PR) with DexaBEAM as second salvage therapy, whereas in 3 patients receiving ICE after DexaBEAM failure only 1 patient achieved an OR (1 PR). Median progression-free survival (PFS) was significantly higher in the DexaBEAM group (6.4 vs. 2 months; P=0.01). Median overall survival (OS) was not different between the two groups (22.8 vs. 29.8 months; P=0.72), most likely due to the good response rate of patients to DexaBEAM as 2nd salvage regimen after failure of ICE chemotherapy. Major adverse event in both groups was myelosuppression with higher but tolerable treatment-related toxicity for patients in the DexaBEAM group. Conclusions: In this retrospective comparison DexaBEAM salvage chemotherapy was superior to ICE for patients with relapsed or refractory aggressive PTCL for remission induction prior to autologous transplantation, with higher but manageable treatment-related toxicity.
