Backtracking Leukemia-Typical Somatic Mutations in Cord Blood

OBJECTIVES:

Primary Aim 1: To obtain stored cord blood and dried bloodspots of pediatric leukemia patients in Project:EveryChild.

Secondary Aim 2: To conduct preliminary backtracking and characterization of ALL- and AML-typical somatic mutations in cord blood and dried bloodspots.

OUTLINE:

Accrue patients with ALL and AML who indicate having banked cord blood at birth through the APEC14B1 intake questionnaire

Inclusion criteria

• The patient must have a diagnosis of acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML).
• Stored diagnostic pre-treatment samples corresponding to the patient's original diagnosis of leukemia must be available for request from either the COG Biopathology Center or a treating institution
• The patient must be enrolled on APEC14B1 with consent to future contact and indicate that cord blood was stored at birth in the APEC14B1 registry intake data.
• The patient must also have been registered with COG by a North American (limited to the U.S. and Canada) member institution.
• ≤ 25 years old at the time of original diagnosis with ALL or AML
• The patient must be able to understand written and spoken English or Spanish
• All patients must provide their consent/assent, as appropriate, and for patients under the age of majority at least one parent or legal guardian must provide consent as well
• All institutional, FDA, and NCI requirements for human studies must be met

Exclusion criteria

• Patients who responded that cord blood was not stored at birth are excluded. Patients without stored diagnostic, pre-treatment leukemia samples at either the COG Biopathology Center or their treating institution are excluded.
