Abstract
BACKGROUND AND PURPOSE: Osteosarcoma is an aggressive malignant bone tumor in children and adolescents, which is more likely to recur and metastasize at the early stages. Cancer stem cells (CSC, CD133 is a biomarker of cancer stem cells), angiogenesis, and vasculogenic mimicry (VM) are closely related to tumor metastasis and recurrence. In this study, we investigated the associations among CD133, aldehyde dehydrogenase 1 (ALDH1), and VM in osteosarcoma, and their associations with clinical characteristics. METHODS: Positive rates of CD133, ALDH1, and VM in 96 whole osteosarcoma tissue samples were detected by immunohistochemistry (IHC) and histochemistry staining. Patients' clinical data were also collected. RESULTS: Positive rates of CD133, ALDH1, and VM were significantly higher in osteosarcoma tissues compared with the control tissues. Positive rates of CD133, ALDH1, and VM were positively associated with lymph node metastasis, distant metastasis, Enneking stages, and patients' overall survival (OS). A multivariate analysis indicated that the positive rates of CD133, ALDH1, and VM, as well as the Enneking stages were independent prognostic factors of osteosarcoma. CONCLUSION: The positive rates of CD133, ALDH1, and VM could represent potential biomarkers for metastasis and prognosis, which suggests these molecules might be promising therapeutic targets for osteosarcoma.
