In Myelodysplastic syndrome, epigenetic treatments such as Azacitidine and Decitabine have been highlighted in phase 3 studies. However, as the 1st line treatment, it has not been evaluated the head to head comparison of two drugs. This study is a retrospective study to compare the efficacy of two drugs.

Primary Outcome Measures:
  • Response rate [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Compare Azacitidine and Decitabine's treatment response rate in MDS patients

Secondary Outcome Measures:
  • Efficacy [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To compare hematologic improvement between Azacitidine and decitabine

  • Survival rate [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To compare survival rate between Azacitidine and decitabine

  • Number of participants with non-hematologic toxicities [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    To compare toxicity between Azacitidine and decitabine

  • infection rate [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    To compare infection rate between Azacitidine and decitabine

Enrollment: 300
Study Start Date: January 2011
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
200 MDS patients taking Azacitidine will be assessed
100 MDS patients taking Decitabine will be assessed

Detailed Description:

Among 300 MDS patient, 200 of them have been taking Azacitidine and 100 of them have been taking Decitabine. Medical chart of these patients will be reviewed to assess the efficacy and safety between two agents.
