• Patients with MDS and with blasts > 10% (RAEB-II) are eligible.
• Patients with extramedullary relapse only (i.e., leukemia cutis or other extramedullary site) are eligible as long as disease can be monitored.

Patients with fungal lung infections must have had treatment for at least one month and have proof of regression prior to enrollment. Patients may be on antimicrobials at the time of therapy.

• Initial required laboratory values:

  • Total Bilirubin \< 2 X upper limit of normal.
  • AST \& ALT \< 3 X upper limit of normal (if elevated liver enzymes thought likely due to Leukemic infiltrate discuss with the Principal Investigator and the BrUOG Central Office).
  • Creatinine \< 2 mg/dl.
  • \< 15,000 K/uI blast count-Hydroxyurea can be used to decrease count if more than 15,000 K/ul.
• Patients must have an ECOG performance status of 0-2.
• Patients must receive and sign a full informed consent.
• Patients should not have co-existing medical illnesses which would limit survival \< 12 weeks.
• No known history of HIV.
• The safety of decitabine in human pregnancy is unknown. Based on animal studies, decitabine may cause fetal harm when administered to a pregnant woman. Therefore, it is important that you do not become pregnant or father a child while receiving study medication and for 2 months afterwards because the drugs in this study may affect an unborn baby.
• If you are a woman capable of becoming pregnant (not surgically sterile or post-menopausal), you must have a negative pregnancy test before beginning treatment.

If you do become pregnant, suspect you are pregnant, or if your partner becomes pregnant while you are on this study, you must notify your study doctor immediately. If you become pregnant, you will be taken off this study.

In addition, you must not breast feed at any time you are on this study since any drugs you are taking may also affect the child.

If you are capable of giving birth to or fathering a child, you must agree to use a form of birth control (examples of effective birth control are: a condom or a diaphragm with spermicidal jelly; oral, injectable, or implanted birth control; or abstinence) that is medically acceptable to your study doctor while taking part in this research study.
