摘要
The purpose of this study was to examine the association of the expression of Sox4 and β-catenin with the prognosis of osteosarcoma. A total of 108 cases of conventional osteosarcoma were involved in this study and 28 cases of osteochondroma served as controls. The expression of Sox4 and β-catenin was detected by using immunohistochemical staining and Western blotting. The results showed that Sox4 and β-catenin were over-expressed in 67（62.03%） and 62（57.41%） of 108 osteosarcoma cases, while in only 3（10.71%） and 5（17.86%） of 28 controls, respectively（P〈0.05 for all）. The expression of Sox4 and β-catenin was associated with the distant metastasis, pathological grade and Enneking stage of patients with osteosarcoma（P〈0.05 for all）. The mean overall survival time and the 5-year-survival rate in osteosarcoma patients with Sox4 and β-catenin over-expressed were significantly reduced as compared with those in Sox4 and β-catenin low-expression group（P〈0.05 for all）. Cox multifactor regression analysis revealed that the distant metastasis, Enneking stage, and the expression of Sox4 and β-catenin were independent risk factors of patients with osteosarcoma（P〈0.05 for all）. The findings indicated that overexpression of Sox4 and β-catenin is associated with a poor prognosis of osteosarcoma.
