简要总结
The purpose of this study is to determine the safety and feasibility of conditioning with fludarabine, busulphan and thymoglobuline in patients with myelodysplastic syndrome (MDS), myelodysplastic/myeloproliferative disorders (MDS/MPD) or acute myeloid leukaemia (AML) undergoing haematopoietic stem cell allograft with granulocyte colony-stimulating factor (G-CSF)-mobilised peripheral blood stem cells (PBSC) (or bone marrow) from HLA compatible sibling donors.

- •Age >18 years
- •Myelodysplastic Syndromes with IPSS Intermediate-2 or High.
- •Poor risk acute myeloid leukaemia, de novo or transformed from MDS
