Risk-Based Classification System of Patients with Newly Diagnosed Acute Lymphoblastic Leukemia

Overview

About this study

This research study is developing a risk-based classification system for patients with newly diagnosed acute lymphoblastic leukemia. Gathering health information about patients with acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Patient has newly diagnosed acute leukemia:
    • > 25% blasts on a bone marrow (BM) aspirate or
    • If a BM aspirate is not obtained or is not diagnostic of acute leukemia, the diagnosis can be established by a pathologic diagnosis of acute leukemia on a BM biopsy or
    • A complete blood count (CBC) documenting the presence of at least 1,000/uL circulating leukemic blasts
  • Adequate samples must be provided to the reference and/or COG-approved cytogenetics laboratories to allow completion of the studies needed for risk-stratification
    • If a BM aspirate is not performed, or adequate material cannot be obtained, peripheral blood (PB) can be substituted for BM if there are at least 1,000 circulating blasts/uL (i.e., a white blood cell [WBC] count of 10,000/uL with 10% blasts or a WBC count of 5,000/uL with 20% blasts)
    • If an adequate BM aspirate cannot be obtained and there are fewer than 1,000/uL PB blasts, the patient is not eligible for AALL08B1 or a frontline COG ALL clinical trial
  • Patient has suspected ALL:
    • Patients whose blast morphology is obviously myeloid, or whose blasts are myeloperoxidase positive, should not be enrolled on AALL08B1; however, patients with true biphenotypic or bilineage leukemia (i.e., patient presents with blasts with significant expression of multiple lymphoid and myeloid markers such that assignment to a single lineage is not possible) are eligible to enroll in AALL08B1 for cell banking
  • Samples must be sent to a COG-approved cytogenetics laboratory, and COG Reference Laboratory studies
  • All patients and/or their parents or legal guardians must sign a written informed consent
  • All institutional, Food and Drug Administration (FDA) and National Cancer Institute (NCI) requirements for human studies must be met

Exclusion Criteria:

  • Patient must not have received prior cytotoxic therapy except for steroids or intrathecal chemotherapy
  • Patient must not have secondary ALL that developed after treatment of a prior malignancy with cytotoxic chemotherapy
