Morbidity and transplant-related mortality of CBV and BEAM preparative regimens for patients with lymphoid malignancies undergoing autologous stem-cell transplantation

Abstract

CBV and BEAM are the two most frequently used regimens for patients with lymphoma undergoing autologous hematopoietic stem-cell transplantation (ASCT). This study compared their morbidity and transplant-related mortality (TRM) in 113 patients with non-Hodgkin's lymphoma (69) and Hodgkin's disease (44) undergoing ASCT between 1990 – 2004. CBV (cyclophosphamide, 6000 mg m⁻²; VP-16, 750 mg m⁻²; and high-dose BCNU, 800 mg m⁻²) was administered to 75 patients and 38 received BEAM (BCNU, 300 mg m⁻²; VP-16, 800 mg m⁻²; cytarabine, 800 mg m⁻²; melphalan, 140 mg m⁻²). Patients in the BEAM group had a significantly higher median age (p = 0.002) and were more heavily treated before ASCT (p = 0.003). More patients showed active disease at transplant in the BEAM group (p = 0.04). Sinusoidal obstruction syndrome (SOS) was more frequent in the CBV group (11% vs 0%, p = 0.048). There were 20 (18%) transplant-related deaths, 18 in the CBV and two in the BEAM group. Infectious complications (12 patients, seven with pneumonia) and SOS (four) were the most frequent causes of death. The cumulative incidences of TRM were 25% in the CBV and 7% in the BEAM group (p = 0.02). CBV thus produced a higher incidence of SOS and TRM than BEAM in this series.
