Approximately half of patients with relapsed chemosensitive disease achieve robust responses with BEAM (BCNU, etoposide, cytarabine, and melphalan) and autologous stem cell rescue. The scarcity of comparative studies further limits alternative treatment protocols, such as the MITO/MEL (mitoxantrone, melphalan) protocol. In this retrospective multicenter study, we compared the BEAM and MITO/MEL regimens used before autologous hematopoietic stem cell transplantation (ASCT) in terms of efficacy and side effects in patients with Hodgkin lymphoma. Data met international accreditation rules. Before ASCT, 108 patients received the MITO/MEL, and 34 patients received the BEAM. The median follow-up time was 36 months in the MITO/MEL group (range, 3-178) and 23 months in the BEAM group (range, 4-99). After ASCT, the 3-year expected overall survival and disease-free survival rates were 86.1% and 86.1% for the MITO/MEL group and 91.3% and 76.5% for the BEAM group, respectively. Although 50% of patients developed febrile neutropenia attacks in the MITO/MEL group, this rate was 91.1% in the BEAM group. The grade II and higher rates of hepatic, renal, gastrointestinal, and cardiac toxicities were similar in both groups. However, the rate of pulmonary toxicity was determined to be 1.9% in the MITO/MEL group and 29.4% in the BEAM group (P < .001). The MITO/MEL conditioning regimen seems to be as effective as the BEAM regimen but has better tolerability in terms of pulmonary toxicity and may be used as an alternative option if necessary, depending on the comorbidity status of the patient.
