“…The FLAG and FLAG‐idarubicin (Ida) regimens, which combine fludarabine (FDR), high dose cytosine arabinoside (ara‐C) and granulocyte colony stimulating factor (G‐CSF) with or without Ida, have recently been used with encouraging results in poor risk acute myeloid leukaemia (AML), MDS and refractory or relapsed acute lymphoblastic leukaemia (ALL) (Estey et al , 1994; Visani et al , 1994; Clavio et al , 1996; Nokes et al , 1997; Parker et al , 1997; Deane et al , 1998; Fleischhack et al , 1998; Montillo et al , 1998; Ferrara et al , 1999; Steinmetz et al , 1999; Jackson et al , 2001). The toxicity of this combination regimen was also found to be low.…”
