Acute Lymphoblastic Leukemia (ALL) - Pediatric

Approximately 6,000 individuals are diagnosed with acute lymphoblastic leukemia (ALL) each year in the United States. Children comprise about 60% of these cases, making ALL the most common type of pediatric cancer. [1]

ALL is the most common indication for allogeneic hematopoietic cell transplantation (HCT) in patients <18 years with hematological malignancies, according to CIBMTR® (Center for International Blood and Marrow Transplant Research®), our research program. [2]

 

Advances

Recent research in pediatric ALL, including an evidence-based review [3], provides new data for clinical decision-making and supports the following recommendations:

  • Allogeneic HCT is recommended for pediatric ALL patients who experience primary induction failure, but subsequently achieve a first complete remission (CR1)
  • Allogeneic HCT and intensive chemotherapy with imatinib have equivalent early outcomes for Ph+ ALL in CR1
  • HLA-matched related and unrelated donors provide equivalent outcomes
  • Myeloablative total body irradiation containing conditioning regimens are recommended

Numerous clinical research studies have definitely shown that minimal residual disease (MRD) has a clear prognostic impact in pediatric ALL, and clinicians are increasingly using it for disease risk stratification. [4,5]

Chimeric antigen receptor T cell (CAR-T) therapy for treating relapsed/refractory pediatric and young adult patients with B-cell ALL received FDA approval in 2017. [6]

Outcomes

Review outcomes for allogeneic transplantation in children with ALL below. View additional ALL slides showing demographic data and transplant trends.

Data in this section have been prepared by CIBMTR.

Referral Timing Guidelines

These guidelines highlight patient and disease characteristics that put patients at risk for disease progression and who should be referred for a consultation for allogeneic transplantation. [7]

Transplant Consultation Guidelines: Acute Lymphoblastic Leukemia (ALL) - Age <15 years

High-resolution HLA typing is recommended at diagnosis for all patients

  • Infant at diagnosis
    • unfavorable genetics
    • age <3 months with any WBC, or <6 months with WBC>300,000 at presentation
  • Primary induction failure
  • Presence of measurable (also known as minimal) residual disease after initial therapy
  • High/very high-risk CR1, including:
    • Philadelphia chromosome positive slow-TKI responders or with IKZF1 deletions; Philadelphia-like
    • iAMP21
    • 11q23 rearrangement
  • First relapse
  • CR2 and beyond, if not previously evaluated
  • Chimeric Antigen Receptor Therapy (CAR-T)

    • Philadelphia chromosome positive or Philadelphia-like
    • iAMP21
    • 11q23 rearrangement
    • B-cell with poor-risk cytogenetics

CAR T Cell Therapy Video for Patients

In this easy-to-understand video, Linda J. Burns, M.D., Vice President, Health Services Research, and Scott Kerwin, R.N., M.N., C.C.R.C., C.C.R.N., explain what CAR T cell therapy is, who it may help, what the treatment is like, potential risks and benefits, questions to ask your doctor, and more. View the video and share it with patients and caregivers who are looking for information on CAR T therapy as a treatment option.
