Age, menopause, clinical stage, tumor grade, tumor type, tumor size, lymph node metastasis and CTHRC1 level were correlated with the overall survival (p = 0.039, 0.011, < 0.001, 0.001, 0.025, 0.014, < 0.001 and 0.004, respectively; Table 2). Here, CTHRC1 is linked to metastatic malignant neoplasm in the lymph nodes.
