title: Mafosfamide (ASTA-Z-7654) in vitro treatment of bone marrow does not eradicate Philadelphia-positive cells in chronic myeloid leukaemia.
abstract: Bone marrow from 9 patients with Ph1+CML was treated in vitro with varying concentrations of Mafosfamide in order to test the hypothesis that selective pharmacological killing of Ph1-positive cells in CML is feasible. A marked difference in sensitivity to Mafosfamide of CFU-GM was observed, but at all concentrations 100% persistence of Ph1+ cells was noticed. We conclude that, in classical cases of Ph1-positive CML, Mafosfamide purging of bone marrow will not be effective.
