NDC80 and metastatic malignant neoplasm in the lymph nodes: As shown in Table 2, the following univariate analysis indicates NDC80 expression, tumor invasion, lymph node metastasis, and distant metastasis were significant prognostic factors for CSS (P < 0.001, P = 0.001, P < 0.001, P < 0.001), whereas NDC80 expression, tumor differentiation, tumor invasion, lymph node metastasis, and distant metastasis were for DFS (P < 0.001, P = 0.018, P < 0.001, P < 0.001, P < 0.001).
