@@@@Background:Nowadays, the research of the pathogenesis of osteosarcoma is becoming intensive. BMI-1 gene, as a popular element in the research of carcinogene, has a lot of research evidences in the recent malignant tumors studies. However, it has few evidences in the osteosarcoma research comparatively. Objective:To explore the expressions of BMI-1 gene in bone tumors and their clinical correlations. M Methods:Adopting immunohistochemical staining to detect the expression of BMI-1 protein in 80 cases of bone tumor tissues and 20 cases of non-tumorous bone tissues. Of the 80 cases of bone tumor, there were 30 cases of osteosarcoma (including En-neking stage I, II, and III), 20 cases of osteochondroma, another 20 cases of chondrosarcoma, and 10 cases of Ewing's sarcoma. Then compare the main clinical data within the osteosarcoma cases, and use the Chi-square test in its statistical processing. Results:The positive expression rates of the BMI-1 protein were all relatively high in the osteosarcoma, chondrosarcoma and Ewing's sarcoma cases, there were no statistical differences between them. While that rates were significantly low in the osteochondroma and non-tumorous bone tissues cases, there existed statistical differences. The statistical differences also ex-isted in the positive expression rates of the benign bone tumors and the malignant bone tumors. While there were no statisti-cal differences between each two of the positive expression rates of BMI-1 protein in the Enneking I, II, III stage of osteosar-coma;Nor statistical differences among different ages, sexes, tumor locations or postoperative metastasis. But a higher posi-tive expression rate of BMI-1 protein was more likely to be found in younger patients, and the rise of the that rate could pre-dict a tendency of the osteosarcoma metastasis. Conclusions:BMI-1 gene can be one of the molecular targets of the osteosarcoma, it has the potential to be a reference in-dex in judging the developing of the osteosarcoma and its prognosis. Revealing its molecular mechanism in osteosarcoma will be helpful in explore the pathogenesis of osteosarcoma.
