Abstract AIMS: Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decade of life. Evaluation of prognosis of patients with osteosarcoma is limited to clinical parameters whereas molecular markers of tumor aggression have not yet been identified. Inhibition of apoptotic cell death could play a role in the development or progression of neoplasia. Survivin is a member of the inhibitor of apoptosis (IAP) protein gene family and is expressed both during normal fetal development and in human cancer. METHODS: The localization and distribution of survivin was investigated immunohistochemically in high-grade osteosarcomas by an indirect immunoperoxidase method. RESULTS: Survivin was detected in the cytoplasm in 23/40 and in the nucleus in 20/40 cases of osteosarcoma. Nuclear localization of survivin expression was significantly correlated with a prolonged survival (P=0.0347) but cytoplasmic staining showed no correlation with patient outcome. CONCLUSIONS: The results of this study indicates that the evaluation of survivin expression might be a useful prognostic marker in osteosarcoma. Patients with osteosarcoma exhibiting nuclear survivin expression could potentially benefit from stratification of neoadjuvant chemotherapy.
