Thus, to determine whether DKK1 level and β-catenin accumulation could be predictive for the prognosis of 63 cases of chondrosarcoma patients, the Kaplan-Meier analysis was performed, and showed that DKK1 level had a significant effect on the overall survival (P = 0.015, Figure 3A). Here, DKK1 is linked to chondrosarcoma.
