  Purpose

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.

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]
  • 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. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Compare epigenetic modifications of chromatin. Cells will be rapidly fixed and chromatin will be prepared in order to directly probe protein-DNA complexes by [ChIP-seq]chromatin immunoprecipitation or [ChIP-chip analysis] chromatin immunoprecipitation [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Perform protein analysis. Tumor cells will be rapidly frozen for subsequent isolation of total protein or specific fraction of cellular proteins (i.e. nuclear, cytoplasmic, membrane proteins). [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Perform immunohistochemical and FISH analysis of neuroblastoma, osteosarcoma, retinoblastoma, ESFT and soft tissue sarcomas. Tissue microarrays will be prepared from samples collected in this study. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Cell isolates obtained from primary and metastatic tumor specimens will be used to establish cell lines and orthotopic xenografts in immunocompromised mice. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Perform analysis of cell growth, metastasis and sensitivity to chemotherapy. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Evaluate the extent of immune cell infiltration and their functional status in pediatric solid tumors utilizing flow cytometric analysis of fresh tumor samples. [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Evaluate tumor-associated macrophages (TAMSs) post-therapy to locate gene expression patterns, markers and functional correlates of the tissue repair properties of macrophages in the post-therapy microenvironment. [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Tumor tissue - Tumor tissue will be obtained from patients with a diagnosis of neuroblastoma, retinoblastoma, osteosarcoma, Ewing sarcoma or soft tissue sarcoma at some or all of the following time points: initial biopsy, primary tumor resection, time of disease recurrence. Whole blood - 5 ml of whole blood will be collected from each patient and be used as a matched control. Bone marrow aspiration - 5ml of bone marrow will be taken at the time a patient is having a bone marrow aspirate performed and processed to remove only tumor cells.

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.
