Backgroud. Osteosarcoma is a primary malignant tumor with a high tendency to form metastasis and poor prognosis. Consequently, finding effective early indicators of metastases is crucial for identifying and treating high-risk patients. CXCR4 and MMP-2 have been found to strongly correlate with invasion and metastasis of malignant tumors, including osteosarcoma. Materials and Methods. Our study evaluated CXCR4 in conjunction with MMP- 2 as an important clinicopathological prognostic predictor for metastasis and overall survival of osteosarcoma. 73 patients' clinical data and pathological samples were retrieved for the study. A median time of 36 months follow-up was performed to evaluate for tumor metastasis and patient survival. CXCR4 and MMP-2 proteins in tumor tissues were detected by immunohistochemistry on paraffin-embedded tissue sections. Results. The positive expression rate of CXCR4 and MMP-2 was 68.5% and 54.8% respectively, and of the 45 patients who developed distal metastasis, 33 and 28 patients had positive expression of CXCR4 and MMP-2 respectively. The median metastasis-free survival was 72.00 months in the CXCR4-negative group and 14.00 months in the CXCR4 positive group. Furthermore, median overall survival was 73.77 and 24.00 months in these same two groups. Further, the median metastasis-free survival was 66.51 months in the MMP-2 negative group and 9.00 months in the MMP-2 positive group. The median overall survival was 75.07 and 19.00 months in these same two groups. MMP2 and metastasis remained the significant and independent prognostic factors for metastasis-free survival and overall survival by using the COX regression model adjusted for the multivariate predictors of survival. Conclusion. Our results suggest that metastasis and MMP- 2 are both independent prognostic indicators for metastasis-free and overall survival of osteosarcoma patients.
