Overall Status
Core binding factor (CBF) positive acute myeloid leukemia (AML) consist of 15% of patients in overall AML, expected to harbor a favorable prognosis. However, around a half of cases relapses. Accordingly, more sophisticated classification in CBF positive AMLs is essential to achieve further improvement in the treatment outcome. The current study is designed to evaluate CBF positive AML patients with genome-wide SNP array and KIT mutation study in CBF positive AML patients diagnosed at the Samsung Medical Center and Hwasun Chonnam National University Hospital, Korea between 1994 and 2008.

1. Construction of the CBF positive AML patient cohort: clinical database establishment (including treatment outcomes and prognosis) and extraction/storage of tumor cell DNAs from marrow samples, then processing of Affymetrix SNP array 6.0.

2. Construction of prognostic predictive model using pharmacogenomics with the results of genotypes and copy number variations (CNVs).

3. Detection of hidden microscopic cytogenetic lesions with SNP array technique, and correlation with clinical outcomes in CBF positive AML.

4. Detection of KIT, FLT3/ITD, and NPM1 gene mutation and its correlation with clinical outcomes in CBF positive AML.

The current study attempts to analyze genetic data of core binding factor (CBF) positive acute myeloid leukemia (AML) using genome wide SNP array technique with tumor DNAs collected at the time of diagnosis.

1. To detect microcytogenetic lesions and will analyze its prognostic significance

2. To analyze genome-wide genotypes and copy number variations (CNVs) using pharmacogenetic approach and will construct a prognostic predictive model

3. To detect KIT, FLT3/ITD and NPM1 mutation and evaluate its prognostic significance. The present study will establish individualized therapy for CBF positive AML, will provide a basis for molecular marker guided clinical trial in CBF positive AML.
