Allogeneic hematopoetic stem-cell transplantation for patients with relapsed or refractory lymphomas: comparison of high-dose conventional conditioning versus fludarabine-based reduced-intensity regimens.

Background: Allogeneic hematopoetic stem-cell transplantation (alloHSCT) has curative potential for poor risk lymphoma patients due to the graft-versus-lymphoma effect. High non-relapse mortality with conventional high-dose conditioning indicates the necessity for less toxic transplant strategies.

Patients And Methods: Between 1992 and 1999, 25 patients [median age 37 (20-60) years] with relapsed or refractory non-Hodgkin's lymphoma (NHL, n = 20) or Hodgkin's disease (HD, n = 5) received an alloHSCT in our institution.
