WT1 and thyroid gland carcinoma: In addition, higher WT1 expression predicted worse survival time in thyroid cancer patients (Fig. 2J), and the AUC of the ROC curve reached 0.8, 0.8, 0.66 and 0.69 at 1 year, 2 years, 4 years and 8 years, respectively, indicating a superior predictive performance of WT1 for thyroid cancer patients (Fig. 2K).
