Other prognostic factors that were significantly associated with DFS in the univariate analyses were age (P < 0.0001), tumor size (P = 0.0205), malignancy grade (P = 0.0300), menopausal status (P = 0.0104), and hormone receptor status (P = 0.0034), which is in accordance with previous findings [15]. Here, NR4A1 is linked to neoplasm.
