High-dose chemotherapy followed by autologous hematopoietic stem cell transplant (AHSCT) is a standard of care for patients with relapsed Hodgkin lymphoma. Different conditioning regimens before AHSCT have been used, with the 2 most common being BEAM (carmustine, etoposide, cytarabine, and melphalan) and BUCYVP16 (busulfan, cyclophosphamide, and etoposide). We retrospectively compared the outcomes of patients treated with BEAM (n = 128) or BUCYVP16 (n = 105) followed by AHSCT. After a median follow-up of 4.2 years for BEAM and 3.8 for BUCYVP16 from AHSCT, the 5-year cumulative incidence of relapse was 29% with BEAM compared with 56% with BUCYVP16 (P < .001). Median progression free survival (PFS) and overall survival (OS) were not reached with BEAM and were 2.0 and 7.8 years with BUCYVP16, respectively. Improved PFS (P < .001) and OS (P = .001) were observed with BEAM for patients who needed transplant within 24 months from diagnosis and for patients not in complete remission (non-CR; P = .001 and P < .001, respectively) at AHSCT. In this large retrospective comparison the use of BEAM conditioning before AHSCT resulted in a statistically significant improved PFS and OS and lower relapse compared with BUCYVP16. This supports the use of BEAM as a frontline conditioning regimen before AHSCT for early relapsed and non-CR Hodgkin lymphoma.Full Text
