Molecular Analysis Of Solid Tumors
St. Jude Children's Research Hospital
1,000 participants

OBSERVATIONAL
Conditions
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.
Eligibility
Inclusion Criteria5
- 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 biopsy, 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 informed consent 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 Criteria1
- Patient is known to be Hepatitis B, Hepatitis C and/or HIV positive.
