Acute Lymphoblastic Leukemia (ALL) - Pediatric

Approximately 6,000 individuals are diagnosed with acute lymphoblastic leukemia (ALL) each year in the United States. Children and adolescents younger than 20 years comprise about 54% 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. [2] Research suggests that allogeneic HCT is recommended for pediatric ALL patients who experience primary induction failure, but subsequently achieve a first complete remission (CR1). Human leukocyte antigen (HLA) matched related and matched unrelated HCT provide equivalent outcomes.[3]

Outcomes 

Data in this section have been prepared by the CIBMTR® (Center for International Blood and Marrow Transplant Research®). The CIBMTR is a research collaboration between the National Marrow Donor Program® (NMDP)/Be The Match® and the Medical College of Wisconsin.

HCT Consultation Timing Guidelines  

The National Marrow Donor Program® (NMDP)/Be The Match® and the American Society for Transplantation and Cellular Therapy (ASTCT) have jointly developed guidelines for transplant consultation and referral timing based on disease characteristics. [4] The National Comprehensive Cancer Network Clinical Practice Guidelines (NCCN Guidelines®) were consulted when developing these guidelines and are a valuable tool in determining risk stratification. [5] 

Our 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. [4]

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)

Transplant Consultation Guidelines: Acute Lymphoblastic Leukemia (ALL) - Age 15-39 Years 

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

  • High/very high-risk CR1 including:
    • Philadelphia chromosome positive or Philadelphia-like 
    • iAMP21 
    • 11q23 rearrangement 
  • B-cell with poor-risk cytogenetics 
  • First relapse 
  • CR2 and beyond, if not previously evaluated

CAR-T Cell Therapy Video for Patients 

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] 

In this easy-to-understand video, Linda J. Burns, M.D., former Vice President, Health Services Research, and Scott Kerwin, R.N., M.N., C.C.R.C., C.C.R.N., former Clinical Trial Patient Education Specialist at the NMDP/Be The Match, 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. 

Clinical Trials Search and Support  

The NMDP/Be The Match offers the Be The Match® Jason Carter Clinical Trials Search and Support (CTSS) program, which can provide clinical trial navigation to your patients. The CTSS Program was created to help people with blood cancers or blood disorders and their families find and join clinical trials.
