These genes were also shown to be overexpressed and may be involved in osteosarcoma tumorigenesis. COPS3<\/jats:italic> encodes a subunit of the COP9 signalosome implicated in the ubiquitination and ultimately degradation of the P53 tumor suppressor. To determine the relation between COPS3<\/jats:italic> amplification, P53<\/jats:italic> mutation, and patient outcome in osteosarcoma, tumors from a large cohort of patients with high\u2010grade osteosarcoma and long\u2010term clinical follow\u2010up were examined.<\/jats:p><\/jats:sec>METHODS.<\/jats:title>Quantitative real\u2010time polymerase chain reaction (PCR) was performed to detect copy number changes for COPS3<\/jats:italic>, as well as additional genes (NCOR1<\/jats:italic>, TOM1L2<\/jats:italic>, and PMP22<\/jats:italic>) from the 17p11.2 amplicon, in 155 osteosarcomas from a prospective collection of tumors with corresponding clinical data. Univariate and multivariate analyses were performed to assess differences in survival between groups.<\/jats:p><\/jats:sec>RESULTS.<\/jats:title>Amplification of COPS3,<\/jats:italic> detected in 31% of the osteosarcomas, was strongly associated with large tumor size (P<\/jats:italic> = .0009), but was not associated with age at diagnosis, site, sex, and tumor necrosis. COPS3<\/jats:italic> amplification was significantly correlated with a shorter time to metastasis with an estimated hazard ratio (HR) of 1.61 (95% confidence interval [CI], 1.02\u20132.55) in univariate analysis (log\u2010rank test, P<\/jats:italic> = .042). However, in an a priori multivariate Cox model including the other clinical parameters, the HR for COPS3<\/jats:italic> amplification decreased to 1.32 (95% CI, 0.82\u20132.13, P<\/jats:italic> = .25), mainly due to the strong correlation with tumor size. COPS3<\/jats:italic> amplification and P53<\/jats:italic> mutation frequently occurred in the same tumors, suggesting that these are not mutually exclusive events in osteosarcoma. Although not statistically significant, patients whose tumors exhibited both molecular alterations tended to be more likely to develop metastasis compared with patients with either COPS3<\/jats:italic> amplification or P53<\/jats:italic> mutation alone.<\/jats:p><\/jats:sec>CONCLUSIONS.<\/jats:title>COPS3<\/jats:italic> is the likely target of the 17p11.2 amplicon. COPS3 may function as an oncogene in osteosarcoma, and an increased copy number may lead to an unfavorable prognosis.
