Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
238 patients were recruited between October, 2002 and June, 2008.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
238 patients were enrolled on the study. This report is based on results for 223 patients. 15 patients were excluded for the following reasons: 7 were switched to lymphoid-directed therapy shortly after enrollment, 6 were determined to be ineligible shortly after enrollment (wrong diagnosis), and 2 were not randomized.

  Outcome Measures
  Show All Outcome Measures

1.  Primary:   Minimal Residual Disease (MRD).   [ Time Frame: Day 22 MRD measurement ]

2.  Secondary:   Proportion of Minimal Residual Disease (MRD)+ Patients Who Become MRD- After One Course of Gemtuzumab Ozogamicin (GO)   [ Time Frame: Consolidation I ]

3.  Secondary:   Proportion of MRD Reduction After One Course of Cytarabine + Daunomycin + Etoposide (ADE) + GO   [ Time Frame: Induction II ]

4.  Secondary:   Proportion of Patients Experienced Toxicity of Cytarabine + Daunomycin + Etoposide (ADE) + GO.   [ Time Frame: Induction II ]

5.  Secondary:   To Estimate the Overall Event-free Survival (EFS) of AML Patients Who Undergo Risk-adapted and Genotype-directed Therapy   [ Time Frame: Five Year ]

6.  Secondary:   To Assess Whether Inhibition of DNA Synthesis is Greater After High-dose Ara-C (HDAC) Than After Low-dose Ara-C (LDAC) Therapy   [ Time Frame: Measurements were assessed in Induction I chemotherapy ]

7.  Secondary:   Relationship of Inhibition of DNA Synthesis and Clinical Response   [ Time Frame: Measurements were assessed in Induction I chemotherapy ]
