Study Details

Study Description

Brief Summary

The purpose of this study is to confirm the safety and the therapeutic effect of Decitabine in the treatment of elderly Acute Myeloid Leukemia (AML) patients.

Condition or Disease	Intervention/Treatment	Phase
Untreated Adult Acute Myeloid Leukemia Effect of Drugs Drug Safety	Drug: Decitabine	Phase 3

Detailed Description

The outcome of the elderly AML patients is very poor. No obvious progress was achieved in this field. Decitabine is a kind of specific DNA methylation shift enzyme inhibitor. It can reverse the DNA methylation and induce the differentiation and apoptosis of the tumor cells. Recent studies about decitabine in the treatment for elderly AML patients had achieved inspiring results and indicated that low dose decitabine maybe a good choice for elderly AML patients. So in this research the investigators plan to evaluate the safety and the therapeutic effect of decitabine in the treatment of elderly AML patients.

Arms and Interventions

Arm	Intervention/Treatment
Other: Decitabine, CR rate,OS,EFS,RFS Therapeutic effect and safety of 10 days of decitabine. Acute myeloid leukemia,no acute promyelocytic leukemia.	Drug: Decitabine Number of Cycles: 4 cycles. Dose and drug delivery(decitabine): The 1st cycle: 20 mg/m2, (iv,>1 hour) d1-10 of each 28 day cycle. The 2nd-4th cycle:If bone marrow blast cells≥5%, the following cycle is the same as the 1st cycle. If bone marrow blast cells<5%, the following cycle:decitabine 20 mg/m2, (iv,>1h) on d1-5 of each 28 day cycle. If Grade 4 neutropenia（<0.5×10E9/L）come arise after 5 days' cycle of decitabine and lasts more than 14 days in last cycle,the next cycle will decrease dose to 4 days(20 mg/m2, IV ,>1h, on d1-4 of each 28 day cycle).If Grade 4 neutropenia（<0.5×10E9/L）come arise after 4 days' cycle of decitabine and lasts more than 14 days in last cycle,the next cycle will decrease dose to 3 days(20 mg/m2, IV,>1h, on d1-3 of each 28day cycle).
