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

Secondary Outcome Measures:
  • Genome-wide associations [ Designated as safety issue: No ]
  • Genomic regions associated with osteosarcoma [ Designated as safety issue: No ]
  • Functional implications of promising genetic variants associated with osteosarcoma [ Designated as safety issue: No ]

Estimated Enrollment: 1000
Study Start Date: January 2009
Detailed Description:



  • Conduct a large-scale candidate gene-association study in patients with osteosarcoma using cases from clinical trials COG-P9851 and COG-AOST06B1.


  • Conduct a genome-wide association study of osteosarcoma.
  • Fine-map genomic regions associated with osteosarcoma to identify putative functional loci.
  • Investigate the functional implications of promising genetic variants associated with osteosarcoma.

OUTLINE: This is a multicenter study.

Blood samples undergo polymorphism analysis of common single-nucleotide polymorphisms and haplotypes to examine genetic variation, gene-gene interactions, and the population structure.
