High-dose CEB vs BEAM with autologous stem cell transplant in lymphoma.

ABSTRACT

Between January 1996 and July 2002, 72 patients with non-Hodgkin's lymphoma or Hodgkin's disease underwent high-dose chemotherapy with autologous stem cell transplant conditioned with either cyclophosphamide, etoposide, carmustine (CEB) or carmustine, etoposide, cytarabine, melphalan (BEAM) at a single institution. In all, 52 patients received CEB and 20 patients received the BEAM regimen. Patient characteristics that were significantly different between the two groups are tumor grade and extranodal involvement (P = 0.0196, 0.0341, respectively). Regimen-related toxicities examined yielded only diarrhea occurring at a higher rate in the BEAM group (81 vs 51%, P = 0.0026), although cases were milder (92 vs 57%). Patients treated with CEB developed mucositis at a slightly higher rate (79%) than patients treated with BEAM (75%), but this difference did not reach statistical significance. However, the mucositis that occurred within the BEAM group was predominately mild (67%) in contrast to the predominance of moderate to severe cases in the CEB group (74%). In addition, patients treated with CEB required growth factor support for a longer time than patients treated with BEAM (P = 0.0399). Response rates were high in both groups, with trends favoring the BEAM group. Overall survival was higher after treatment with BEAM than with CEB (84 vs 60%).
