This phase II study of B cell NHL and HL examined the safety and efficacy of BuCyE.
Individually adjusted busulfan was based on preconditioning PK.
BuCyE outcomes were compared with contemporaneous recipients of BEAM registry data.
BuCyE provided adequate disease control and safety in B cell NHL patients ≤ 65 years.
BuCyE produced worse PFS in HL patients when compared with BEAM.
