• <Inclusion Criteria>
• Age: 1year~19years of age at diagnosis
• Patients who are newly diagnosed Pre-B ALL and meet one of the following criteria
  • High-risk group according to the National Cancer Institute (NCI)/Rome: Age greater than or equal to 10 years and less than 19 years at diagnosis, or white blood cell count greater than or equal to 50 x 10\^9/L at diagnosis
  • If extra-bone marrow lesions are identified at the time of diagnosis, Central nervous system involvement (CNS3) or testicular involvement
  • High-risk gene variants:
  • KMT2A rearrangement intrachromosomal amplification of chromosome 21 (iAMP21)
  • ● If subjects are under the age of 10 at the time of diagnosis and took steroids for more than 24 hours within two weeks before the diagnosis, the risk group will be determined by the presence of a whole blood test within three days before starting steroids. If a whole blood test is performed within three days before beginning steroids, the risk group will be assessed based on the white blood cell count in the test. If there is no whole blood test before starting steroids, subjects are classified as a high-risk group. If subjects are ten or older at diagnosis, pre-diagnosis steroid treatment will not affect the risk classification.
• Newly diagnosed T cell ALL
  • <Exclusion Criteria>

• Patients with Down syndrome
