title: Allogeneic transplantation after a conditioning regimen with ifosfamide, carboplatin and etoposide (ICE).
abstract: Successful allogeneic hematopoietic transplants require conditioning regimens with sufficient immunosuppression to allow acceptance of the allograft. Cyclophosphamide, in combination either with TBI or with chemotherapeutic drugs, is the keystone of commonly used regimens. The toxicities of TBI and tumor resistance to cyclophosphamide create a niche for alternative, chemotherapy-based conditioning regimens. We report successful allogeneic stem cell transplantation after an ifosfamide-based regimen with ifosfamide 20 g/m2, carboplatin 1.8 g/m2 and etoposide 3 g/m2 (ICE) in divided doses over 6 days. Engraftment was prompt with neutrophils > or = 20 x 10(9)/l on day +10 and platelets > 20 x 10(9)/l on day +18. Engraftment of donor cells was documented by chromosome analysis and by VNTR analysis. An ifosfamide-based regimen provides sufficient immunosuppression for hematopoietic allograft acceptance in the absence of cyclophosphamide or of TBI.
