Genome-wide gene expression profiling on pre-chemotherapy biopsies of osteosarcoma patients who developed metastases within 5yrs (n=34) and patients who did not develop metastases within 5yrs (n=19)

GSE21257 Homo sapiens Expression profiling by array 53 samples Submitted 2011/02/11 Platform GPL10295
Summary
High-grade osteosarcoma is a malignant primary bone tumor with a peak incidence in puberty. Overall survival of patients with metastatic disease is approximately twenty percent. Mechanisms behind the development of metastases in osteosarcoma are unknown. To identify gene signatures that play a role in metastasis, we performed genome-wide gene expression profiling on pre-chemotherapy biopsies of osteosarcoma patients who developed metastases within 5yrs and patients who did not develop metastases within 5yrs.
