Study summary

This study will prospectively characterize the molecular, cellular and genetic properties of primary and metastatic neuroblastoma, osteosarcoma, retinoblastoma, Ewing sarcoma family of tumors, soft tissue sarcomas, adrenocortical tumors and liver malignancies. These cell isolates will be used for gene expression array analysis, genomic analysis by [SNP] single nucleotide polymorphism chip, array [CGH] comparative genomic hybridization and next generation sequencing, and [TEM] transmission electron microscopy analysis. Additionally cell lines and orthotopic xenografts will be created from the obtained tumor specimens.

The specificity of TCRs will be examined by comparing paired TCR from peripheral blood and tumor infiltrating CD4+ and CD8+ T cells. Epigenetic studies will be performed looking at the methylation profile of these cells and to investigate the anti-tumor T cell response both pre- and post-PD1 inhibition.

Read the detailed description

Each year approximately 2,200 children in the United States are diagnosed with neuroblastoma, osteosarcoma, Ewing sarcoma family of tumors (ESFT), retinoblastoma, soft tissue sarcomas, adrenocortical tumors and liver malignancies. These aggressive pediatric solid tumors are developmental tumors that initiate during periods of tissue growth and morphogenesis in the neural crest, bone and soft tissues. The overall survival rate of these tumors in the advanced stage is less than 30%. Despite intensive efforts over the past three decades using multiple therapeutic modalities including chemotherapy, surgery, radiation, autologous bone marrow transplant and biological agents there has been modest improvement in the long-term survival of these advanced stage pediatric solid tumors. A better understanding of the molecular, cellular and genetic changes that occur in the developing tissues as tumors form could improve the treatment of these devastating cancers. In particular, chemotherapeutic agents may be more effectively targeted to key regulatory enzymes or proteins if the study had a better understanding of the pathways that are disrupted as cells progress from preneoplastic lesions to metastatic disease. The specific aim of this proposal is to identify the changes in gene expression that occur in neuroblastoma, retinoblastoma, osteosarcoma, Ewing sarcoma family of tumors [ESFT] and soft tissue sarcoma cells and to correlate these changes with genetic and cellular changes in the tumor cells. [RNA] ribonucleic acid and genomic [DNA] deoxyribonucleic acid will be isolated from neuroblastoma, retinoblastoma, osteosarcoma, ESFT [Ewing sarcoma family of tumors] and soft tissue sarcomas (both primary and metastatic lesions) following surgery or bone marrow aspiration of previously untreated patients. Additional testing will be conducted on tumor samples at any point during or following therapy in which a surgical specimen is obtained. When there is sufficient tumor sample remaining after pathological analysis and banking, fresh primary tumor cells will be used to prepare orthotopic xenografts and to establish models of each disease that recapitulate the advanced forms of neuroblastoma, osteosarcoma, Ewing sarcoma family of tumors [ESFT], retinoblastoma and soft tissue sarcomas. For a small group of these excess samples, this study will perform fixation for electron microscopy and process the samples for [TEM] transmission electron microscopy analysis. These studies will complement our active research program characterizing the molecular, cellular and genetic features of genetically engineered mouse models of each of these diseases. Biological samples from the cohort of patients treated at St. Jude Children's Research Hospital will be complemented with samples collected and processed by collaborating institutions around the world. Samples collected from international collaborators will be used for analysis of [DNA] deoxyribonucleic acid and [RNA] ribonucleic acid to complement the St. Jude Children's Research Hospital cohort. Through this collaboration the study anticipates that they will be able to obtain enough fresh tumor samples to improve their understanding of multistage tumorigenesis in pediatric solid malignancies.

Study population

Patients identified at St. Jude Children's Research Hospital and collaborating institutions with a suspected or known diagnosis of neuroblastoma, osteosarcoma, retinoblastoma, Ewing sarcoma or soft tissue sarcoma based initial diagnostic workup and evidence of gross disease amenable to excision.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Must have a suspected or known diagnosis of neuroblastoma, osteosarcoma, Ewing sarcoma family of tumor or soft tissue sarcoma based on the initial diagnostic workup and evidence of gross disease amenable to excision. Specimens may be collected at some or all of the following time points: initial , bone marrow aspiration procedures, tumor resection, and at time of possible relapse.
  • Patients with a diagnosis of retinoblastoma based on initial diagnostic workup and who require enucleation may be enrolled if there is no active therapeutic or biologic protocol for retinoblastoma.
  • The patient or his/her legal guardian, as appropriate, must provide written within 30 days of the removal of the first collection of tissue/bone marrow/blood sample for this protocol.
  • The patient is being seen at St. Jude Children's Research Hospital or at a collaborating institution.
  • Patients must be less than or equal to 25 years old at the time of enrollment.

Exclusion criteria

Exclusion Criteria:

  • Patient is known to be , and/or positive.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. Perform analysis of gene expression profiles. [RNA] ribonucleic acid will be isolated from fresh frozen tumor specimens and hybridized to Affymetrix gene expression arrays.

    Time frame: 5 years

Secondary outcomes

  1. Perform analysis of large chromosomal alterations such as amplifications and deletions. [DNA] deoxyribonucleic acid isolated from the tumor and blood samples will be hybridized to array [CGH] comparative genomic hybridization chips.

    Time frame: 5 years

  2. Perform analysis of focal alterations in the genome including amplification, deletion and loss of heterozygosity (LOH). DNA isolated from the tumor and blood samples will be hybridized to [SNP] single nucleotide polymorphism chips.

    Time frame: 5 years

  3. Perform analysis of point mutations. DNA isolated from the tumor and blood samples will be sequenced using next-generation sequencing technology to determine the sequence of the entire genome.

    Time frame: 5 years

  4. Perform analysis of cell morphology. Tissue samples will be fixed in a buffer suitable for transmission electron microscopy and processed for [TEM] transmission electron microscopy analysis.

    Time frame: 5 years

  5. Compare micro RNAs in tumors. Micro RNAs will be isolated from the total [RNA] ribonucleic acid left over from the gene expression analysis described above. These samples will be used for micro [RNA] chip analysis or deep sequencing.

    Time frame: 5 years

  6. Compare epigenetic modifications of [DNA] deoxyribonucleic acid. Genomic DNA will be isolated and DNA methylation will be analyzed across the genome to determine if this epigenetic process is altered in the tumor samples.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 12, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
