DNA Biomarkers in Tissue Samples From Patients With Osteosarcoma
Therapeutically Applicable Research to Generate Effective Treatments (TARGET) for Osteosarcoma

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes the occur in DNA and identify biomarkers related to cancer. DNA analysis of tumor tissue may also help doctors predict how well patients will respond to treatment.

PURPOSE: This research study is studying DNA biomarkers in tissue samples from patients with osteosarcoma.


  • To comprehensively detect genomic, epigenomic, and transcriptomic aberrations in tissue samples from patients with osteosarcoma that may play a role in chemoresistance and metastasis using high-resolution genome-wide technologies.
  • To identify recurrent genetic mutations involved in the pathogenesis of osteosarcoma, especially for the development of chemoresistance and metastatic tumors.
  • To identify and validate these biomarkers for new therapeutic targets for patients with osteosarcoma, especially those with metastatic disease and whose tumors are resistant to standard chemotherapy.

OUTLINE: This is a multicenter study.

Archived tumor tissue and peripheral blood DNA specimens are analyzed for DNA copy number profiling, gene expression profiling, DNA methylation profiling, microRNA profiling, and genomic resequencing. Clinical data including demographics; date of diagnosis, surgery, chemotherapy, recurrence, progression, and death; imaging; toxicity; and pathologic data elements associated with the specimens are also collected and analyzed.
