Overview
Brief Summary
This study is to evaluate efficacy and safety of Imatinib in two groups of patients; all patients should be diagnosed less than 3 months as chronic myeloid leukemia in a chronic phase. The group A, the reference group, will have 10% or less than 10% of the BCR-ABL level after three month dosing and be maintained their dose of 400mg/day. On the other hand, the group B, will have more than 10% and the dose will be increased from 400mg/day to 600mg/day. The superiority of the group B will be proved by evaluating the MMR rate of these two groups after 12 months of administeration of Imatinib.

Outcomes
Primary Outcomes
MMR rate at 12 months in two groups
Time Frame: 12 months
MMR rate at 12 months in two groups will be compared. Group A is consisted of patients with equal or less than 10% of BDR-ABL, Group B is consisted of patients with more than 10% of BDR-ABL.
Secondary Outcomes
- CMR in group A and B(12 months)
- Survival rate in group A and B(12 months)
- MMR in group A and B(12 months)
- CCyR in group A and B(12 months)
- Progression rate to AP/BC in group A and B(12 months)
- the actual administration(12 months)
