About this study
Official title: Establishing Continuous Cell Lines and Xenografts From Pediatric Cancers for Biological and Pre-Clinical Therapeutic Studies
This laboratory study is collecting and storing tissue, blood, and bone marrow samples from young patients with cancer. Collecting and storing samples of tissue, blood, and bone marrow from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.
Read the detailed description
PRIMARY OBJECTIVES:
- Establish and bank cell lines and/or xenografts from pediatric patients with cancer.
II. Establish continuous cell lines, under carefully controlled conditions, from pediatric patients with cancer.
III. Establish transplantable xenografts in immunocompromised mice from tumor cells that are difficult to establish as continuous cell lines in vitro.
IV. Create a bank of cell lines and generate sufficient vials of cryopreserved cells for distribution to investigators with approved COG biology protocols. V. Characterize cell lines from childhood cancers with respect to DNA short tandem repeat molecular profile as a "fingerprint" of original cell line identity.
VI. Characterize cell lines for the ability for sustained growth in tissue culture and/or as mouse xenografts.
VII. Characterize cell lines for mycoplasma contamination. VIII. Characterize cell lines for expression of molecular makers that confirm the tumor-type of the cell line and the immortal nature of the cells (telomerase) and the expression of molecular markers that may correlate with drug resistance.
OUTLINE: This is a multicenter study.
Specimens are stratified according to disease (acute lymphoblastic leukemia vs acute myeloid leukemia vs lymphoma vs osteogenic sarcoma vs Ewing family of tumors vs rhabdomyosarcoma vs primitive neuroectodermal tumor vs glioma vs astrocytoma vs rhabdoid tumors vs hepatoblastoma vs retinoblastoma vs Wilms tumor vs germ cell tumors vs other diagnoses).
Leftover tissue from diagnostic procedures and/or surgery is cryopreserved and banked. Blood and/or bone marrow are also collected and banked. Cell lines are established and characterized via reverse-transcriptase polymerase chain reaction and/or flow cytometry for biomarkers and by DNA fingerprinting. Markers to be identified may include the following:
NEUROBLASTOMA: tyrosine hydroxylase, protein gene product (PGP) 9.5, GD2, HLA class I, and HSAN 1.2 antigens
EWING FAMILY OF TUMORS: EWS-FLI1, EWS-ERG, and PGP 9.5
RETINOBLASTOMA: interphotoreceptor retinoid-binding protein
ACUTE LYMPHOBLASTIC LEUKEMIA: immunophenotype
ALVEOLOR RHADOMYOSARCOMA: PAX3-FKHR, PAX7-FKHR, and MyoD1
ALL CELL TYPES: telomerase expression including hTR and hTERTMutations of TP53 gene are detected by flow cytometry and/or immunocytochemistry.
No results of these tests are provided to the patient, the patient's physician, or the patient's medical records.

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia, run by Children's Oncology Group at 68 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 24 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 68 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Establishment and banking of cell lines and/or xenografts from pediatric patients with cancer (time frame: Up to 14 years). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 May 2025.
