Expression of CTHRC1 was positively correlated with patient tumor size (P < 0.001), lymph node metastasis (P < 0.001), and clinical stage (P < 0.001), and there was no significant correlation between CTHRC1 expression and patients’ age, gender, or distant metastasis (P > 0.05) in patients with thyroid cancer (Table 5). The gene discussed is CTHRC1; the disease is thyroid cancer.
