Objective: To study the expression of survivin and its relationship with clinical multidrug resistance in osteosarcoma. Methods: By using immunohistochemistry (S-P) method, the expression of Survivin in osteosarcoma, osteochondroma and normal osseous tissue, and the expression of P-glycoprotein in osteosarcoma was detected. Results: Survivin positive expression rate was 65.71% in osteosarcoma, but no expression of Survivin was detectable in osteochondroma and normal osseous tissue. The positive expression rate of Survivin was significantly associated with Enneking clinical stages and histological typing (WHO), but no relationship was found among Survivin expression and age, sex and tumor location. The positive expression rate of P-glycoprotein was 45.71%. There was a significant correlation between Survivin and p-glycoprotein. Conclusion: Survivin overexpression was significantly associated with clinical multidrug resistance in osteosarcoma. It could be a potential target for treatment of osteosarcoma.
