Outcome Measures

Primary Outcomes (1)

  • To find out distribution of genetic polymorphisms genes related to the pharmacodynamics of the ALL therapy

    * The distribution of each genetic polymorphism is descriped. * The differences in genetic polymorphism between risk groups (high vs. standard) are analyzed using the chi-square test or Fisher's exact test.

    up to 3 years from diagnosis

Secondary Outcomes (3)

  • To see the ethnic difference of genetic polymorphisms related to the chemotehrapeutic drugs of ALL

    whenever after diagnosis and genetic analysis (no time frame needed)

  • To find out relation of genetic polymorphisms and clinical outcome (relapse or survival)

    up to 3 years from diagnosis

  • To find out risk factors of relapse and death

    up to 3 years from diagnosis

Study Arms (1)

Pharmacogenetic analysis, ALL

Biospecimen

Retention: SAMPLES WITH DNA

1. Candidate genes exhibit polymorphisms and encodes proteins that are involved in the pharmacokinetics and pharmacodynamics of antileukemic agents * Priority was given to polymorphism that were demonstrated to be associated with phenotypes in both clinical and preclinical studies. * Candidate genes : CYP3A4\*1B, CYPA5\*3, GSTM1 deletion, GSTP1 313, GSTT1 deletion, MDR exon 21, MDR exon 26, MTHFR 677, MTHFR 1298, NR3C1 1088, RFC 80, TPMT-1 238, TPMT-1 460, TPMT-1 719, VDR intron 8, VDR FokI, ITPA 2. Blood sample at complete remission→DNA extraction 3. Total-Plex (multiplex) PCR amplification 4. Luminex system analysis
