In contrast 3 years OS had no statistically significant differences concerning CTSK expression (P = 0.154), tumor grade (P = 0.162), tumor histologic type (P = 0.418), TNM stage (P = 0.140), tumor site (P = 0.25), and gender variables (P = 0.059, Fig. 6). The gene discussed is CTSK; the disease is neoplasm.
