NR4A1 and neoplasm: On a multivariate Cox regression analysis, histologic grade (hazard ratio [HR], 2.12; 95% CI, 1.24 to 3.64; P = .006), four or more positive ALNs (HR, 2.02; 95% CI, 1.41 to 2.90; P < .001), hormone receptor status (HR, 1.82; 95% CI, 1.32 to 2.49; P < .001), and tumor size (HR, 0.62; 95% CI, 0.40 to 0.97; P = .037) were independent prognostic factors for DFS.
