Original Article


Osteosarcoma is a highly aggressive bone disease with a tendency to metastasize to the lung. The 5-year survival of patients with metastatic osteosarcoma is only 20 %. Many studies have demonstrated SDF-1/CXCR4 and MMP9 play important roles in the metastasis of malignant tumors, including osteosarcoma. The aim of this study was to investigate the association of CXCR4 and MMP9 expression with clinicopathological features and pulmonary metastasis in osteosarcoma. Using tumor tissue microarrays, we analyzed the expression of CXCR4 and MMP9 among 34 primary osteosarcomas with pulmonary metastasis and 62 primary osteosarcomas without metastasis. A median time of 57.5 months (range: 6 to 171 months) follow-up was performed to evaluate tumor metastasis and the patient survival. The prognostic values were determined by univariate Kaplan-Meier survival analysis and multivariate Cox proportional hazard model analysis. The accuracy of oncologic outcome prediction was evaluated by receiver-operating characteristics (ROC) curves (AUC). The expression of CXCR4 and MMP9 was significantly correlated in tumor tissues (P = 0.026). Both CXCR4 and MMP9 were independent predictors for overall survival and metastasis-free survival by Cox multivariate analysis, and high expression for both CXCR4 and MMP9 were even more significant and better biomarkers for osteosarcoma metastasis and survival. The combination of CXCR4 and MMP9 high expression is very likely to be a valuable independent predictor of lung metastasis and survival in osteosarcoma patients.
