abstract：:Osteosarcomas are primary tumors of bone that most often develop in adolescents. They are characterized by complex genomic changes including amplifications, deletions, and translocations. The chromosome region 17p11.2p12 is frequently amplified in human high grade osteosarcomas (25% of cases), suggesting the presence ...
