This study is a prospective (the study follows a group of individuals over time), open label (all people involved know the identity of the intervention), multicenter, single arm (one group of patients receiving the same treatment), observational study to observe the response rate and safety of decitabine when treating patients with myelodysplastic syndrome with decitabine. Decitabine is to be administered as long as there is evidence of clinical benefit. It will be assessed if the treatment duration could be prolonged by appropriate toxicity management such as an active antibiotic prophylaxis or dose and schedule modification, and whether this leads to potentially increased clinical benefits such as higher response rate, longer time to Acute Myeloid Leukemia, and prolonged overall survival. For safety evaluation, adverse events and peripheral blood findings will be collected. The patient will receive decitabine intravenous injection 20mg/m2 once a day for 5 consecutive days every 4 weeks.
The purpose of this study is to investigate the overall response rate (ORR) and safety when treating patients with myelodysplastic syndrome with decitabine. Decitabine is to be administered as long as there is evidence of clinical benefit.
