DKK1 and chondrosarcoma: The potential association of deregulation of Wnt/β-catenin signaling with chondrosarcoma development provides the rationale for deeply exploring the underlying role of DKK1 and β-catenin in chondrosarcoma in vivo, and determines whether DKK1 and beta-catenin can be predictive for overall survival of patients with chondrosarcoma.
