About

Myelodysplastic syndrome (MDS) is widely recognized as a clonal hematopoietic stem cell disorder. Decitabine has been approved for the treatment of all subtypes of myelodysplastic syndrome (MDS). However, the use of decitabine is often limited by its severe toxicity represented by myelosuppression even at relatively low doses. In lower-risk patients (including IPSS low and int-1 risk groups), treatment mainly aims at improving cytopenias, especially anemia. However, although several drugs may improve anemia, sometimes durably, most of lower risk MDS eventually require red blood cell (RBC) transfusions during their disease course. Long term RBC transfusions lead to iron overload mainly due to an increase in reticulo-endothelial iron recycling.Cardiac, liver and endocrine (diabetes mellitus) dysfunction due to iron overload and often leading to fatal outcome has been reported in heavily transfused lower risk MDS patients. To date, the optimal regimen for decitabine treatment is not well established. In this study, we perform a prospective analysis to explore the decitabine schedule for the treatment of lower risk myelodysplastic syndrome patients with transfusion dependent.

Full description

The investigators are undertaking a single-center, single-arm study of 50 lower risk myelodysplastic syndrome patients with transfusion dependent from Shandong University Qilu Hospital . All the participants are selected to receive ultra small dose decitabine treatment (given intravenously at a dose of 3.5mg/m2, qd x 5d, every four weeks for one cycle). A routine blood examination is performed twice every week. Bone marrow (BM) is examined with routine aspirate smear and G-banding analysis every 1-2 treatment courses to evaluate responses.Adverse events are also recorded throughout the study.
