STIL and metastatic malignant neoplasm in the lymph nodes: In the multivariate analysis, high sTIL (HR: 0.664, P = 0.019 for DFS; HR: 0.608, P = 0.005 for OS) was identified as independent better prognostic factor, and lymph node metastasis (HR: 1.950, P = 0.010 for DFS; HR: 2.118, P = 0.004 for OS) and clinical stage (HR: 2.040, P = 0.004 for DFS; HR: 2.119, P = 0.002 for OS) were identified as independent worse prognostic factors as shown in Table 2.
