Pediatric Autologous Hematopoietic Stem Cell Transplantation (PDQ®): Treatment - Health Professional Information [NCI]

This information is produced and provided by the National Cancer Institute (NCI). The information in this topic may have changed since it was written. For the most current information, contact the National Cancer Institute via the Internet web site at http://cancer.gov or call 1-800-4-CANCER.

Collection and Storage of Autologous Hematopoietic Stem Cells

Collection and Storage of Autologous Hematopoietic Stem Cells

Autologous hematopoietic stem cell transplantation (HSCT) procedures require collection of growth-factor–mobilized peripheral blood stem cells (PBSCs) from patients using leukapheresis. Bone marrow can be used for autologous transplants, but PBSCs lead to quicker blood count recovery, resulting in less transplant-related toxicity.

Patients being considered for autologous HSCT are generally given chemotherapy to determine tumor responsiveness and minimize the risk of tumor contamination in their bone marrow. After a number of rounds of chemotherapy, patients undergo the leukapheresis procedure, either as their blood counts recover from chemotherapy or during a break between chemotherapy treatments. Growth factors such as granulocyte colony-stimulating factor are used to increase the number of circulating stem and progenitor cells (CD34+ cells). Collection centers monitor the CD34-positive number in the patient and product each day to determine the best time to begin collection and when collection is complete. Patients with low numbers of CD34-positive cells before collection can often have their cells successfully collected using alternative mobilization approaches (e.g., addition of plerixafor).[1] The collected PBSCs are cryopreserved for later use. After completion of an intensive preparative regimen using high-dose chemotherapy, which varies according to the tumor type, the PBSCs are administered to the patient at the time of transplant.

General Indications and Considerations for Autologous Procedures

General Indications and Considerations for Autologous Procedures

Autologous HSCT Indications for Solid Tumors and Lymphomas

In pediatrics, the most common autologous HSCT indications are for the treatment of some solid tumors and lymphomas.

Autologous transplants have also been used to reset the immune system in patients with severe autoimmune disorders and to enable engraftment of genetically modified autologous hematopoietic stem cell progenitors to correct or ameliorate inherited disorders (e.g., immunodeficiencies, metabolic disorders, and hemoglobinopathies). These indications are not covered in this summary.

Indications for HSCT vary over time as risk classifications for a given malignancy change and the efficacy of primary therapy improves. It is best to include specific indications in the context of complete therapy for any given disease.

With this in mind, links to sections in specific PDQ summaries that cover the most common pediatric autologous HSCT indications are provided below.

  1. Neuroblastoma.
    • Refer to the Treatment of High-Risk Neuroblastoma and Recurrent Neuroblastoma in Patients Initially Classified as High Risk sections in the PDQ summary on Neuroblastoma Treatment for more information.
  2. Brain tumors. Indications for young patients to reduce or eliminate cranial radiation therapy; indications for responsive tumors at relapse.
    • Refer to the Treatment of Childhood High-Grade Astrocytomas and Treatment of Recurrent Childhood High-Grade Astrocytomas sections in the PDQ summary on Childhood Astrocytomas Treatment for more information.
    • Refer to the Treatment of Childhood CNS Atypical Teratoid/Rhabdoid Tumor section in the PDQ summary on Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment for more information.
    • Refer to the Treatment of Childhood Medulloblastoma, Treatment of Childhood Pineoblastoma, and Treatment of Recurrent Childhood Medulloblastoma and Other CNS Embryonal Tumors sections in the PDQ summary on Childhood Medulloblastoma and Other Central Nervous System Embryonal Tumors Treatment summary for more information.
  3. Germ cell tumors (GCTs) (intracranial and extracranial).
    • Refer to the Nonstandard Treatment Options for Recurrent Malignant GCTs in Children section in the PDQ summary on Childhood Extracranial Germ Cell Tumors Treatment for more information.
    • Refer to the Treatment Options for Recurrent Childhood CNS GCTs section in the PDQ summary on Childhood Central Nervous System Germ Cell Tumors Treatment for more information
  4. Retinoblastoma.
    • Refer to the Treatment of CNS Disease, Treatment of Synchronous Trilateral Retinoblastoma, Treatment of Extracranial Metastatic Retinoblastoma, and Treatment of Progressive or Recurrent Extraocular Retinoblastoma sections in the PDQ summary on Retinoblastoma Treatment for more information.
  5. Hodgkin lymphoma.
    • Refer to the Treatment of Primary Refractory or Recurrent Hodgkin Lymphoma in Children and Adolescents section in the PDQ summary on Childhood Hodgkin Lymphoma Treatment for more information.
  6. Non-Hodgkin lymphoma.
    • Refer to the Treatment options for recurrent or refractory Burkitt lymphoma/leukemia, Treatment Options for Recurrent or Refractory Lymphoblastic Lymphoma, Treatment Options for Recurrent or Refractory Anaplastic Large Cell Lymphoma, Treatment options for lymphoproliferative disease associated with primary immunodeficiency, Treatment options for peripheral T-cell lymphoma, and Treatment options for cutaneous T-cell lymphoma sections in the PDQ summary on Childhood Non-Hodgkin Lymphoma Treatment for more information.

For autologous transplants to result in cure of malignancies, the following must apply:

  • A dose-intensified chemotherapy regimen (with or without radiation therapy) with hematopoietic stem cell support is used to achieve a significantly higher cell kill than could be achieved without the use of hematopoietic stem cell support. This approach may include increased tumor kill in areas where standard-dose chemotherapy has less penetration (central nervous system).
  • Meaningful percentages of cure or long-term remission from the disease must occur without significant nonhematopoietic toxicities that would otherwise limit the therapeutic benefit achieved.

The tumor-specific activity and intensity of agents used for autologous regimens have been shown to be important in improving survival.

The contamination of the collected stem cell product by persistent tumor cells is one concern with autologous approaches for these and other tumor types. Although many techniques have been developed to remove or purge tumor cells from products, studies have shown no benefit to tumor purging.[1]
