FIGO stage (log − rank = 13.084, P < 0.001), tumor diameter (log − rank = 14.211, P = 0.001), depth of invasion (log − rank = 6.108, P = 0.047), degree of differentiation (log − rank = 13.084, P = 0.001), lymph node metastasis (log − rank = 39.522, P < 0.001), vascular invasion (log − rank = 25.180, P < 0.001), CHI3L1 expression (log − rank = 24.431, P < 0.001, as shown in Figure 2(c)), and MVD expression (log − rank = 8.522, P = 0.004, as shown in Figure 2(d)) were correlated with PFS prognosis (P < 0.05). The gene discussed is CHI3L1; the disease is metastatic malignant neoplasm in the lymph nodes.
