“…The best conditioning regimen before AHCT in patients with relapsed/refractory lymphoma is an undefined issue. Commonly used regimens in this scenario are BEAM (BCNU, etoposide, cytarabine, and melphalan) [8,9], BEAC (BCNU, etoposide, cytarabine, cyclophosphamide) [9], high-dose ICE (hICE; ifosfamide, carboplatin, and etoposide) [10], CMV (cyclophosphamide, melphalan, and etoposide) [11], CBV (cyclophosphamide, BCNU, and etoposide), combination regimens including total body irradiation (TBI) [12], and rituximab or I131-tositumomab combined with BEAM [13]. Few studies were reported comparing conditioning regimens in terms of toxicity and efficacy [9,13,14,15,16].…”
